Zhengzhou airport to Zhengzhou Central Station

1. It's about 50 kilometers from Zhengzhou Xinzheng airport to Zhengzhou Central Station. If there is no traffic jam on national highway 107 or take the ring expressway, it may take about 40 to 50 minutes, nearly an hour.
the bus from central station to Nanyang takes half an hour, and it may take longer in the evening, but it's available 24 hours, and the bus fare may be about 80.
if you don't sit at the station, You can take a taxi directly from the airport to the intersection of Qilihe Expressway and wait for the bus. All the cars in Nanyang get on the expressway from there, and the price will be cheaper.
if you don't take a high-speed bus, you can take a taxi from the airport to lujiaqiao. It's not far from the airport, and it's not a high-speed bus to wait beside 107 National Road.
but it's still recommended that you go to the station to buy a ticket in the evening, It's cold to wait for a bus on the road, and it's easy to be cheated outside. Although the bus at the long-distance bus center station is a little more expensive than other stations, there are more buses.
I'm from Nanyang, and it's worth it to help you. I've been studying in Zhengzhou for four years, and I've been to Xinzheng airport to meet my classmates twice

There are only ten National Forensic centers recognized in China, among which there are three universities: Institute of forensic science and technology, Southwest University of political science and law, forensic center of Sun Yat sen University, forensic center of the Supreme People's Procuratorate, forensic center of the Ministry of public security, forensic center of Beijing public security, forensic center of Southwest University of political science and law, forensic center of Sun Yat sen University, forensic center of the Supreme People's Procuratorate, forensic center of the Ministry of public security, forensic center of Beijing public security Shanghai public security forensic center,

Guangdong public security forensic center, Beijing State Security Bureau forensic center, Institute of forensic science and technology forensic center, forensic science and technology Forensic Institute of the court of the University of law, forensic science center of Sun Yat sen University, Southwest University of Political Science and law forensic center

forensic institutions refer to the institutions that accept the client's appraisal entrustment in litigation activities, follow the ways, methods, steps and relevant rules and standards stipulated by law, use science and technology or expertise to identify and judge the specialized issues involved in litigation, and provide appraisal opinions

In other words, forensic institutions refer to the special units that accept the entrustment of judicial organs or parties, apply professional knowledge and technology, and make identification and judgment activities according to legal proceres in the process of litigation. After accepting the appraisal entrustment, the judicial appraisal institution shall appoint the judicial appraisers in the institution who are qualified for the appraisal

In the process of litigation, judicial expertise refers to a kind of activity in which the judicial organ or the party entrusts the legal appraisal unit to judge and identify the special problems in the case according to the legal procere by using professional knowledge and relevant science and technology

can be specifically divided into: document forensic, trace forensic, trace forensic, computer forensic, audio-visual forensic, forensic pathology, forensic clinical, forensic psychiatry, forensic physical evidence, forensic toxicology, forensic accounting, intellectual property forensic

extended materials:

in China's judicial practice, judicial expertise is an important means to master evidence. There are many kinds of judicial expertise, including forensic expertise, forensic psychiatric expertise, and criminal technology expertise

There are five principles of forensic expertise: the subject of forensic expertise is legal; The identification materials are legal; The appraisal procere is legal; The identification steps, methods and standards are legal; The result is legal

When the evidence based on which the facts of the case can not be determined, judicial expertise can be done. The parties to a civil or administrative case, the criminal suspect, the defendant, the victim, the plaintiff of the incidental civil procere, and other participants in the proceedings, in order to protect their legitimate rights and interests, make a request for judicial authentication to some specialized issues involved in the case to the investigating organ and other departments. p>

3. According to the speed of the two, judge the movement of the object relative to the belt or the movement trend of the object relative to the belt (for example, the belt is moving at the beginning, when we put an object at a speed less than the belt, the object relative to the belt will have a movement trend opposite to the belt speed direction, The friction force is the same as the belt's moving direction...) so we can judge the friction force! In addition, a relative motion proces dynamic friction, that is, f = UN. A relative motion proces static friction, the size of which can only be obtained by force analysis according to the specific situation of the object

4. When the block starts to stand still and put on the belt, the sliding friction to the right starts to accelerate, and the belt receives the opposite friction. When the block speed is increased to the same speed as the belt speed, there is no friction between the two.

5. The force that hinders the relative motion (or tendency) of an object is called friction. The direction of friction is opposite to the direction of relative motion (or relative motion trend)
friction is divided into static friction, rolling friction and sliding friction.
