The refrigerated truck entering the urban area has always been a problem to be solved. It requires the green pass of the urban area. The current traffic management policy sets many restrictions and obstacles for the operation of the freight refrigerated truck , and it is for the enterprises engaged in the production and sales of cold chain food. It's troubled and burdened. Many customers are unable to complete the city's green pass. Not only is the qualification review of the documents cumbersome, but the truck's pass is issued on a pro-rata basis. In response to this problem, members of municipalities and municipalities also participated in the project and actively used policy guidance to improve the existing management model. It was mentioned that “urban distribution and refrigerated trucks have public attributes and are part of public transport, and the marketability of the logistics industry should be restored. Market-oriented and service-based." The municipal traffic commissions have commissioned relevant departments to carry out optimization research on the city’s road traffic management policies. Based on this, they have coordinated with the public security and other relevant administrative departments to further adjust and optimize the management system for issuing freight passes.
At present, there have been many acts of forging counterfeit passes. China has never issued a unified "Green Pass Pass". Any freight vehicle that enjoys the "Green Passage" policy for the transport of fresh agricultural products must not use the "Green Pass" Pass as a living item. For the certification of agricultural product transport vehicles, the preferential policies must be obtained by loading the goods or manifests and passing through the toll gate according to the prescribed lanes. Any vehicle that is obviously illegally loaded, refuses to pass a lane or refuses to accept inspections will no longer enjoy the "green channel" preferential policy. Drivers and drivers need to pay attention: 1. Not all highways in the provinces and cities have green passages, and some newly built expressways do not have any, so please consult in advance before you travel. 2. The free passage of the green passage is not to exceed the limit. The limits that cannot be exceeded are different for each province and city. Some do not exceed 10%, and some may be less. There are many types of fresh produce, seafood is also included, and frozen pork is not. In addition to meeting the requirements of the product, the green channel must be driven according to the prescribed route.
Picosecond Laser
Picosecond pulsed diode Laser features with integrated electronics, narrow pulse duration, high repetition frequency and easy operation. It is widely used in fluorescence excitation, time resolve spectrum, high sensitive absorption spectroscopy, etc.
Picosecond laser has uperior beam quality, best reliability, mode-locked & picosecond Pulsed Laser, pulsed duration could be less than 20 ps. Housed in compact packages, are the perfect choice for design in and integration into OEM instrumentation and systems and also for end user applications in research and development.
