volatile
organic
compounds
common pollution sources include vehicle exhaust, instrial exhaust, petroleum fuel combustion, organic solvent use, etc. It has the characteristics of penetration, fat solubility and volatilization, so it is easy to cause harm to human body through skin contact and inhalation system. Recently, this kind of organic compounds is suspected to be the cause of cancer
the activated carbon itself can not remove heavy metals, but when the activated carbon in 3M is processed, some polymer materials are added, so that the heavy metals in water can be removed. In addition, calcium and magnesium in the water are retained,
the pre filter element should be replaced in about 6 months,
the post filter element should be replaced in 1.5-2 years,
这种方式适合在安装操作系统的时候进行设置,
点击 Tab,打开kernel启动选项,
增加内核参数: net.ifnames=0 biosdevname=0
输入完成之后回车正常安装操作系统就好了
第二种方式
修改网卡配置文件中的 DEVICE= 参数的关于 eth0
[root@ansheng ~]# cd /etc/sysconfig/network-scripts/
[root@ansheng network-scripts]# vi ifcfg-eno16777728
TYPE=Ethernet
BOOTPROTO=dhcp
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
IPV6_FAILURE_FATAL=no
NAME=eno16777728
UUID=8a3eade8-005c-46df-81f2-6e2598457bac
#DEVICE=eno16777728
DEVICE=eth0
ONBOOT=yes
网卡配置文件名称改为 ifcfg-eth0
[root@ansheng network-scripts]# mv ifcfg-eno16777728 ifcfg-eth0
因 CentOS7 采用 grub2 引导,还需要对 grub2 进行修改,编辑 /etc/default/grub 配置文件,在 GRUB_CMDLINE_LINUX 这个参数后面加入 net.ifnames=0 biosdevname=0
[root@ansheng network-scripts]# vi /etc/default/grub
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="rd.lvm.lv=centos/root rd.lvm.lv=centos/swap rhgb quiet net.ifnames=0 biosdevname=0"
GRUB_DISABLE_RECOVERY="true"
用 grub2-mkconfig 命令重新生成GRUB配置并更新内核
[root@ansheng network-scripts]# grub2-mkconfig -o /boot/grub2/grub.cfg
Generating grub configuration file ...

1 Meet the needs of users as much as possible
the reason why users choose to customize software services is that the software on the market can not fully meet their own needs, so they need to customize personalized software, and as a software development company, they should be able to meet the needs of users as much as possible. Maybe you will meet some users who don't understand the principles of software, and then mention some functions that can't be realized. As a software developer, you should patiently explain the reasons why you can't realize them, and provide appropriate solutions to convince users instead of saying that you can't realize them. Only such a software development company is better and can be favored by users
2, high development efficiency
once the user has the demand to choose a software development company to customize the software, it shows that this software is urgently needed for him at present, and he hopes to be able to complete the development and put into use in a relatively short time. So a good software development company after confirming the user needs, should let the professional personnel to carry out software development, and timely communicate with users, in a short period of time to develop the software that makes users satisfied
3. There are quite successful cases
usually, many software development companies need to pay for software development after confirming the demand with users and quoting, that is to say, the payment is before the software is developed. At this time, how can users believe that the company can develop procts that satisfy them
Choose a reliable third-party E-contract deposit platform
how to choose the third party E-contract deposit platform According to the "Internet Finance indivial network lending E-contract security specification", the third-party E-contract deposit platform should have ISO 27001 certification, Ministry of public security information security protection level 3 or higher certification, to ensure the security of E-contract data
Fada E-contract certificate storage platform has obtained ISO27001 authentication of information security management body and three-level authentication of information security level protection. Ov SSL certificate is adopted to realize data encryption transmission and real identity authentication of website affiliated units. At the same time, every E-contract signed on the Fada E-contract deposit platform will be backed up by Alibaba cloud and Microsoft cloud to ensure data security
2. Look at the legal effect of E-contract on the third party E-contract deposit platform
the third party E-contract deposit platform not only provides the functions of E-contract signing, E-contract storage, E-contract verification, E-contract management, but also needs to have reliable electronic signature, time stamp, identity authentication and other technical means to ensure the legal effect of E-contract
the Fada E-contract deposit platform adopts the national authority authentication technology to ensure the true identity of the signing subject of Fada E-contract; The original electronic document data is solidified by using international common hash value technology to easily identify whether the document has been tampered with; Third party timing technology is adopted to accurately record the signing time. Through the above three points, we can effectively ensure that the electronic contract on the legal da da da electronic contract deposit platform has the same legal effect as the paper contract
When there is a judicial dispute, in order to protect the legitimate rights and interests of the online loan platform and all parties, the third-party E-contract deposit platform should be able to provide users with legal and effective identification reports or efficient solutions to contract disputes The Fada E-contract deposit platform can provide users with legal services such as judicial expertise, certificate issuing report and online arbitration, and jointly with Guangzhou Arbitration Commission to launch a "one-stop" online arbitration service system, which is based on the block chain deposit technology and uses the anti usurpation features of the block chain to solidify electronic evidence, providing a strong evidence guarantee for online arbitration. At the same time, Fada is the earliest electronic contract service provider with one key arbitration case and recognized by the court in China. Fada has high legal effect and is easy to be accepted by judges. Once there is a post loan dispute, the online lending platform, borrowers and investors can apply for arbitration through Fada's "online arbitration service system", and the award can be issued in 7 working days at the fastest and 15 working days on average. Compared with traditional arbitration, Fada network arbitration service system is more efficient, which can save users a lot of time and cost4. Look at the contract signing amount of the third-party E-contract deposit platform
the contract signing amount represents the overall data processing capacity and stability of the server. The larger the quantity, the lower the failure rate, which means that the more assured and stable the proct is
as of the first quarter of 2018, the number of third-party E-contract platform users exceeded 73 million, the total number of platform contracts signed reached 500 million, and the average daily number of contracts signed reached 2.7 million. Alibaba, Microsoft (China), uni President Group, Ctrip, Tongcheng travel, Zhong'an insurance, meituan.com, Longhu group, digital China, 51 social security, Kingdee cloud home, building block box, touna.com, zhenai.com, renrenche.com, tujia.com, SAIC datong.com, fango.com and many other well-known platforms have reached in-depth cooperation with Fada E-contract deposit platform
under the general trend of online loan supervision, online loan platforms need to recognize the importance of E-contract certificate keeping, carefully consider and choose the E-contract certificate keeping platform that can really protect themselves, so as to help them stand out from the current severe supervision situation
You can remove it in the settings of Huawei mobile phone, and the removal methods are as follows:
1. Open the mobile phone, find the settings, and click enter to find the security and privacy,
1. After opening the Huawei application market, click "management" above
1. First, Download Kuaiya from Huawei mobile phone and open it
< H2 > extended data
precautions
1. Huawei mobile files can be transferred to the file manager to find the cache file and then transferred through fasttooth. Because the video files are relatively large, it is faster to use fasttooth. If fasttooth is used, it can be found in the synchronous push and then downloaded. Synchronous push is a legitimate resource software game
2. Downloading videos from Huawei mobile phones depends on the ROM size of the mobile phone. Generally, 4GB is the smallest, and the old version of Huawei is not excluded. Downloading Youku, Tudou or other video software can cache them. Generally, adding a bar with a downward arrow is the cache symbol, and it does not rule out that the version right can not cache them
1. The battery has been in standby for a long time, but once it is used, it will power down quickly. One charge is only enough for one day. However, when the card is not inserted, and it is almost not used, it has been discharged for three days, and nearly half of the power is left. But it's OK. The charge is fast. It's full in two hours
2. The privacy space is useless and hard to use. After setting the privacy user, when switching, it must be in the case of information screen, that is, when the screen is on, it cannot be switched. What's more, when switching, there will be a text prompt "switch to * * user". For people who want to see your mobile phone in front of you, what's the privacy??? In addition, if you set up a privacy user, you can also find the option of privacy user in the settings. Anyone who gets your mobile phone or who knows a little about Huawei mobile phone can find this option. What privacy is there??? In addition, the privacy of users and the normal user interface, with a complete set of software, this is really necessary? Waste of space does not mean that the key is in what scenario? Have you ever considered Huawei mobile phones for users? There are also some software, such as backup software, which can't be used in the privacy user interface. Therefore, for the applications installed in the privacy user interface, it's also a problem to save and backup the application data. In fact, the privacy system users need is to hide some of the software they installed, so that others can't find it or see it. Why bother
3. Many details in the settings are not user-friendly. Huawei officially advertises that every operation is completed in three steps. I don't realize it at all. For a simple example, when deleting a short message, you can only choose to delete one by one, or delete the entire folder together. As for some short messages in a conversation box that you want to delete, You can only choose to delete one by one. You can't first select all the messages you want to delete, and then delete them at one time. I haven't used Huawei mobile phones before, but when I see so many people using them, I think it must be very mature, but to be honest, it's really not as good as the rumor. When you enter some passwords, you can only use the built-in input method. When you click the button, you often get feedback, sometimes you don't get feedback, but you often get the illusion that you haven't entered...
4, but it's really good to take photos, but you have to set your own parameters to take good photos
5, the signal is OK, a little stronger than my previous mobile phone, but the WiFi speed is not good. My previous 1000 yuan mobile phone has two WiFi signals, and this one has only one, which is obviously different. There is no volte
6. The overall sound quality is not bad. The sound is loud, but it's a little sharp and uncomfortable when driving to the maximum. In addition, the standard earphone always falls off and doesn't fit properly
7, the screen can only be said to be general and regular
8. I think if the camera is worth more than 2000, the price is still in the past. Otherwise, it is not worth it, and the 4 + 64 3899 is even less. Speaking of this, let's talk about the memory. In the process of using 6G memory, the remaining memory is generally between 3-3.5g
9, Android 7 system is very new, but some things are not perfect. For example, I need to use helium backup and switch to PTP mode, but the mobile phone just can't switch. Although this item can be selected in settings and drop-down menu, it is actually invalid. The system can only operate in charging mode or MTP mode. I call Huawei Technology Department, Their reply is that this is the new version of Google 7.0. Huawei system can't realize this function for the time being, and will add a patch later.
