Both the mathematic models of air brake system and vehicle are very complicated since many differential equations need to be solved and many parameters may be correlated with each other, especially the parameters for the key components, such as brake valve, relay valve and pipelines.

This paper validates this inference, and concludes that the crowding-out effect of tourism over other industries is small in areas with larger tourism scale such as Beijing which is either historical and cultural city, or political and economic center, with an emphasize on tertiary industry development; while the crowding-out effect of tourism over other industries is the largest in areas with smaller travel size, which is either landlocked but rich in tourism resources, or lacks of tourism resources but plays the key position of foreign trade.
Thus, massive material and human resources have been invested to develop diverse tourism industry.
With the increase of investment in tourism, the total output increases despite the impact of the investment on other industries. 3.1.2 With regard to areas with slowly-developing and smaller-scale tourism, they are either landlocked and inaccessible while rich in tourism resources, such as Anhui and Inner Mongolia, or located in coastal areas such as Guangdong Province and Liaoning Province, although lacking tourism resources, but with developed traffic and key position for foreign trade.
Tourism industry is a systematic engineering, demanding mutual promotion and development with transportation, communications, commerce, catering, and financial and other related industries.

Forging method is suitable for mass production due to simple tooth, stripping easy, forging directly in the mold of straight bevel gears, and can shorten the preparation time of gear production and saving material, but forging method requires an expensive mold, and different size specifications of straight bevel gears requires a corresponding mold.

We conduct an intersectant experiment and the status is same, so we can conclude it should be CD material is destroyed
And the up-draw resistor is the key element on the I2C structure, changing the value of the resistor can change the stability and performance of the I2C bus [4].

Several nanocomposite materials have been shown to be 1000 times harder than the bulk component materials.
Applications of nonmaterial's as biosensors have also advanced to a great extent e.g. they represents the integration of biotechnology, molecular engineering, material science, and chemistry.
