文章以质量、动量和能量三大守恒方程和状态方程为基础，考虑了流动气柱的动能损失以及井筒和地层中复杂的传热机理，推导出计算单相气流在井筒不同部位压力和温度的方法。

Aiming at the deficiency,the type of YHK-2 sliding nozzle is developed.The down nozzle adopts rotary-type,and gas springs are arranged to the both sides of a spring box in the structure of the sliding nozzle,then the question of bleeding out is solved and the life of gas spring is lengthened,and the cost of the production can be decreased by 138 Yuan per heat.

针对其不足，开发了YHK-2型滑动水口，把下水口改为旋紧方式，气体弹簧布置在滑动水口机构的两侧弹簧箱内，解决了下水口和下滑板间的穿漏钢问题并提高了气体弹簧的使用寿命，使每炉钢生产费用降低138元以上。

Boyle's law that the density of a gas is proportional to its pressure and Charles' law that the volume is proportional to the temperature, would be exact if gas molecules were points which had no volume and did not attract one another.

假如 气体没有量且彼此不相互吸引的话，玻意耳关于气体密度与压力成正比的定律以及查尔斯关于气体的量与温度成正比的定律就是正确的。

Because gas is free to be entered through air inlet duct ceaselessly in infusion bottle, aeriform quality is increasing ceaselessly, and the basis in solving Boyle's law, ignored this mensurable applicable condition, to the gas of certain quality.

因为输液瓶中不断有空气通过进气管进入，气体质量在不断增加，而解答中根据玻意耳定律，忽视了该定律的适用条件，对一定质量的气体。

TiO2 is known to exist in three distinct structures: two tetragonal phase for anatase and rutile and a third orthornombic phase for brookite. Rutile has the most stable structure and physical and chemical properties. In rutile structure oxygen cavities move quickly so that rutile has better gas sensing respond and become a chief material use for oxygen gas sensors.

其中金红石结构是最为稳定的晶型，不但具有最为稳定的物理、化学性能，而且在金红石结构中，晶格中氧空位的迁移率较高，因而TiO_2金红石结构气敏响应效应较好，从而使金红石结构TiO_2氧化物材料成为氧敏传感器的首选材料之一。

Deliveries of gas may be added to bulk storage tanks containing the same gas from previous deliveries.

一个样品的结果上必须标明已送气体质量是合格的，例如，样品可以是这样：气体在输送前；或加入和混合之后的半成品储罐。

The invention of this technology is pioneer in China, leader in the world, filing the blank in the gas treatment of coal preparation plants in China; 2. Effectively treat the amassing of gas in the bunker in the coal preparation; 3. It can substitute the commonly used axial fans, which can bring in the considerable economic benefit and social benefit.
