Rail transit has long been used as public transport in cities. It plays an increasingly important role. Economic developed countries urban traffic development history tells us that only by large passenger traffic system of urban rail transit (metro and light rail), is an effective way to fundamentally improve the urban public traffic

The spare parts of the car usually remain expensive and whenyou purchase these parts from the mechanic then they would charge thecommission on the spare parts and  will increase the cost of its actual cost.Thus, you should always buy the spare parts  from the office, shop or you canalso order online. But if you have proper repair and  maintenance company online then they will not charge high prices because they want  to build the relationship with customers by providing them excellent services at a  chea pprice and make contracts  with them for a whole year of repairing andmaintenance work in the car.
The rapid development of air filters is closely related to the development of military industry and electronic industry. In the first world war, the use of various chemical agents, asbestos fibre filter paper as the smoke filter layer of military gas masks came into being. The glass fiber filter medium is used in air filtration to obtain a patent in the United States in October 1940. In the 1950s, the United States studied the production process of glass fiber filter paper, and the air filter was improved and developed. In the 1960s, HEPA filters came out; In the 1970s, the filter paper of fine glass fiber was used as the HEPA filter of filter medium, and the filtration efficiency of particle size of 013 micron particle diameter was 99.9998%. Since the eighty s, with the emergence of new test method, use evaluation to improve and to improve the filtering performance requirements, found the HEPA filter there is a serious problem, and he had a higher ULPA filter performance. Countries are still working on it and expect more advanced air filters soon
