The first national traffic management website goes online

At the time of the "National Traffic Safety Day" on December 2nd, 122 traffic was on the Internet. This is China's first nationwide traffic management and traffic safety professional website, and it is also another new measure for public convenience introduced by the public security traffic control department.

The person in charge of the Traffic Management Bureau of the Ministry of Public Security introduced the website, which is a traffic management portal approved by the Ministry of Public Security and organized by the Road Traffic Safety Research Center of the Ministry of Public Security, and is used by national traffic participants, especially private car owners, passenger and freight vehicles, and hazardous chemicals vehicles. Drivers, minors and other key groups are the target of service, and traffic safety education and convenience services are the core content.

Through this website, the majority of netizens can obtain various kinds of traffic safety knowledge, inquire about traffic violation information, consult traffic safety related issues, learn traffic safety laws and regulations, understand traffic management hot events, participate in traffic management discussions, and interact with the traffic control department. You can enjoy all convenience services without leaving home.

In the initial phase of the traffic network line, it will focus on creating the nation’s first quiz platform for traffic management and traffic safety, and the nation’s key information products for motor vehicle and driver traffic violation information search platforms, with the help of news and information, safe travel, vehicle safety, and policies and regulations. , Service Hotline, and Traffic Vientiane 6 Channels, widely disseminate hotspot events, warning works, travel tips, driving tips, service guides and other kinds of information.

According to the introduction, after the 122 online traffic line, it will take full advantage of China’s massive traffic management business data information, public security traffic management departments at all levels, and 270,000 traffic police and other industry resources to start improving public safety awareness and improve traffic management service efficiency. Further implement the service concept of "letting data run errands and let the masses less run", implement the specific requirements of mass line education practice activities, and raise the level of public security traffic management in our country and the quality of national transportation safety to a new height.

High Precision Machining is defined as a process of changing the dimensions or the performance of workpiece with machining facilities. 

According to the temperature of the workpiece while in machining, high precision machining can be divided into cold working and hot working. Usually, machining under indoor temperature, and won't change cause chemical change or phisical phase change is named cold working. On the other hand, if under temperature, higher or lower than room temperature, which will lead to chemical changes or phase changes, it will be called as hot working.

For high precision machining, the machining tolerance can be up to 0.0001-0.001mm, the surface finish Ra can be 0.02-0.1um.

Machining precision is to describe the actual geometrical parameter of the part after machining, such as the size, the form, the position, comparing with the theoretical geometry parameter.  The difference from these two parameters is the machining tolerance. The number of the difference show the machining accuracy, the bigger, the lower of the machining precision, the smaller, the higher machining precision.
