4. APC training certification: with the advent of the information age, enterprise managers in Europe and the United States and other developed countries soon find that the knowledge and skills originally learned by enterprise staff are rapidly out of date or even out of date, thus realizing that the knowledge and skills possessed by employees themselves are also a kind of resource (that is, human resource), and a kind of consumable resource. This kind of resource can only be regenerated and reused through continuous development, otherwise it will be consumed with time. The main way to realize human resources is training and development. The training is mainly aimed at the knowledge and skills required by the existing positions of employees, while the development is focused on the future development direction of employees. In China, the development of human resources started late. APC company, which provides end-to-end AC and DC power supply protection and management solutions for "network uninterrupted", has realized the importance of its own human resource development earlier, and set up the APC training & Development Department, which also arouses the attention of partners and channel dealers to the training of their own engineers and sales personnel. This is a very important reason why APC company can be invincible in the fierce market competition. This paper introces APC's leading training certification system. In terms of training content, APC company subdivides the whole proct technology course into several subjects, and the technical personnel of dealers and end customers can freely choose according to their own situation. At the same time, in order to enable students to keep up with the trend of network and globalization of APC company, the course of basic knowledge of Network UPS is graally developed. At the same time, in order to improve the professional quality of students, APC company will continue to set up personal management and business management courses. APC divides proct technology courses into three levels: Act (APC certified technician), ACE (APC certified engineer) and ACC (APC Certified Technical Consultant). Act is an open and popular certification level, which aims to improve the mass base of APC Network UPS Technology and provide more and better successor talents for APC and its partners; Ace certification is divided into two categories: ACE power and ACE network management. The former is for professionals in the power instry, while the latter is for technicians engaged in network construction and maintenance in the IT instry. The purpose is to help technicians with a certain level grasp more professional and advanced power technology knowledge, and improve their comprehensive technical strength in their jobs; The purpose of ACC certification is to train and develop expert and consultant level technical talents in UPS field (especially in the field of Network UPS), and point out the long-term and further development direction for ACE certified engineers (as shown in the figure). The training mode is flexible and advanced. In terms of training mode, APC company adopts advanced teaching equipment and experimental equipment, and adopts the teaching means of combining self-study, classroom teaching, laboratory teaching and advanced e-learning (electronic teaching), so as to maximize the teaching quality and learning efficiency. At the same time, APC plans to build six training centers in Beijing, Shanghai, Guangzhou, Cheng, Xi'an, Shenyang and other cities, so as to maximize the convenience of study and work arrangement for the technical personnel of dealers and end customers. There are two ways of act certification training: students can obtain knowledge through the Internet at any time and any place. If they pass the online examination, they can obtain act certificate. The homepage of the certification examination system is http:// www.apcc.com.cn/atnd Alternatively, students can take part in the test of APC power management in the certification training of APC global partners, such as Microsoft, HP, Cisco and other companies. If they pass the test, they will get act + network management certificate. Ace certification is for technical or sales personnel with considerable level in it and power supply instry. If the trainees have passed act certification, APC training and development department will help them acquire more professional and advanced technical knowledge and master more accurate instry development trend. Such training not only provides training and development opportunities for indivials, but also helps their companies enhance their technical strength. Students who participate in ace certification can participate in APC intermediate training courses in various training centers, and obtain the certificate after passing the computer examination and experimental examination. The validity period of ACE certificate is 2 years. After the expiration, you need to take the renewal course and pass the examination before you can replace the new annual ace certificate. In compiling Chinese textbooks, APC Greater China training and development department takes practicality as the basic principle. In view of the differences between China's power system and Europe and the United States, APC has made necessary adjustments to many experimental courses, and made corresponding adjustments to the contents of teaching materials according to the different students. In addition, APC also cooperates with the training centers of APC's global strategic partners such as Microsoft, Cisco, IBM, HP, etc. to help students develop more comprehensive training plans and provide sufficient human resources reserves for students and the future of the company. With the rapid development of APC company and its partners in the business, both dealers and end customers put forward higher and higher requirements for APC training courses in content and form. With the advent of the 21st century, the training and development service department is redoubling its efforts to make a breakthrough in training content, training form and training quality, so that at & D can become a human resource training and development consulting expert among the global network UPS experts, and APC's training will enter a new era. In the past three and a half years, APC's Greater China training and development department (at & D) has trained nearly 3000 technical and sales personnel from distributors and end customers in nearly 50 cities in China. Nearly 300 people have passed the examination and obtained the ace certificate of APC certification, and more than 900 people have obtained the act certificate by participating in the certification training of Microsoft, Cisco and HP. These engineers, salesmen and it personnel from various distribution channel agents have increased their proct knowledge and improved their technical level through training, which has played an important role in promoting the business development of various companies, and has also established an indelible contribution to the promotion and popularization of APC's procts in China; Technical personnel from various network UPS proct users are familiar with the proct performance and use methods through training, so that they can more skillfully operate and handle various emergency events in operation, and ensure the continuous and stable operation of the network system.

5. 1. APC
(average
propensity
to
consumption)
average consumption propensity: refers to the proportion of consumption in the income, if expressed by the formula: APC = C / y< MPC (marginal
propensity
to
consumption)
marginal propensity to consume: the ratio between the increased consumption fee and the increased income, that is, the ratio of the increased consumption part in the income of one unit added by knowledge, is expressed in a fair formula: MPC = DC / dy.

6. It should be aps-c. Since the original film machine used the ordinary film size of 36mm x 24mm, it is customary to call the digital SLR machine with the size of the photosensitive element about 36mm x 24mm full frame machine. In order to save cost, the manufacturer also introced a machine with smaller photosensitive elements than the whole frame: APS-C machine. The length and width of the sensor is only 1 / 1.5 (Nikon, Pentax, Sony) or 1 / 1.6 (Canon) of the full frame. Therefore, there is the problem that the equivalent focal length of an APS-C frame camera with a lens needs to be multiplied by a factor of 1.5 or 1.6. Any questions are welcome to add!

7.

APC average propensity to consume: refers to the proportion of consumption in income. If expressed by formula, APC = C / y

APS average propensity to save: refers to the proportion of savings in income. If expressed by formula, APC = s / y

MPC marginal propensity to consume: the ratio between increased consumption and increased income, That is, the ratio of the increased consumption part of 1 unit of income is expressed by the formula: MPC = DC / dy

MPs marginal propensity to save: the ratio between the increased savings and the increased income, that is, the ratio of the increased savings part of 1 unit of income, The formula is: MPC = DS / dy

the relationship between consumption function and saving function. Total income can be divided into consumption and saving, and total income increment can be divided into consumption increment and saving increment. Therefore, the sum of average consumption tendency and average saving tendency is equal to 1, and the sum of marginal consumption tendency and marginal saving tendency is equal to 1. That is: APC + APS = 1, MPC + MPs = 1

extended data:

average propensity to consume, also known as propensity to consume, refers to the proportion of consumption in income. If expressed by formula, it is: APC = C / Y

for example, a social income is 2 trillion yuan, consumption expenditure is 1.5 trillion yuan, and average propensity to consume is 0.75 (1.5 / 2)

It is a concept relative to accumulation tendency. In the long run, consumption tendency is relatively stable, so the influence of income on consumption structure is subject to the relationship between income level and consumption structure

the change law of APC and MPC:

the average propensity to consume APC and the marginal propensity to consume MPC are decreasing, that is, because of the increase of income, consumption also increases, but the growth rate of consumption is smaller than the growth rate of income (APC decreasing), and smaller and smaller (MPC decreasing). The decline of APC and MPC is an important viewpoint of Keynes, which is one of the three laws of Keynes to explain the lack of effective demand

MPC is the slope of the consumption curve C = C0 + by, and the slope of each point on the consumption curve should be equal, but in the long run, the slope of the consumption curve is getting smaller and smaller

APC> MPC, because even if the income is zero, there will be basic consumption C0. Therefore, 0 & lt; MPC< 1

The relationship between consumption and income can be divided into three situations:

C & gt; Y，APC> 1

C< Y，1> APC> 0

C = y, APC = 1

marginal propensity to consume refers to the ratio of the change of consumption amount to the change of consumer income for a certain proct or a certain type of proct. Marginal propensity to consume is used to describe the extent of change in the amount of consumption of a proct e to changes in income

the marginal propensity to consume is always greater than 0 but less than 1

(1) the marginal propensity to consume is positive when the consumption of procts and the income of consumers increase or decrease at the same time

(2) the marginal propensity to consume is negative when the consumer's consumption is opposite to the consumer's income

(3) when the consumption of a proct does not change, no matter how much the income changes, the marginal propensity to consume does not change

8. The representative is ah, ooh, oppopo, Mopo, Mopo, Mopo, Mopo, Mopo, Mopo, Mopo, Mopo, Mopo, Mopo, Mopo, Mopo, Mopo, Mopo, Mopo, Mopo, Mopo, Mopo. You can try to think of words that can be made up of Pinyin.

9. AC is the average cost, APC is the average propensity to consume

10. Activated prothrombin complex concentrate
it is used to treat hemophilia a bleeding which proces inhibitors, and the effective rate is 40% - 60%. Side effects: the incidence of thrombosis is 1% - 2%, repeated use, liver disease, antithrombin deficiency prone to occur, such as use 3-4 times after invalid, should not be used.
