Firstly, the condensation heat transfer of steam-air mixture on the outside of a horizontal smooth tube and four square thread tubes is studied experimentally, and then, the condensation heat transfer on axisymmetrical surfaces as well as vertical plates of any kind of vapors containing noncondensable gases is analyzed theoretically.

本文作者先实验研究含空气的水蒸汽管外冷凝时水平光滑圆管和强化换热圆管的传热特性，实验时控制主流混合气体的压力和空气的质量成分，并探讨建立实验关联式的方法；然后对含不凝气体的蒸气在竖直平板和轴对称壁面上冷凝换热进行理论分析。

Its. OH scavenging activity was nonsensitive to high-temperature and sensitive to oxygen. But treatment of 75 ℃ for 30 min could highly decrease its sensitivity to oxygen.

其清除OH的能力耐高温，但对空气敏感，但75℃、30 min处理可以显著降低葡萄伤流液对空气的敏感度。

By experiments of difference air filtration media's disposal, we analyse the functional change at waterproof、oilproof and photocatalysis for filter material after disposal, and discuss the feasibility of nano-sized photocatalysis material's application in air filtration media's disposal.

本研究为合理实施改善室内空气卫生环境提供了参考数据，3种降低室内空气微生物的方法各有其效和特点，使用时应根据具体情况选定

The experts also simulated the phenomenon of natural fire in Luo Maozai's home: the phosphoreted mineral was decomposed into the gas of phosphoreted hydrogen under the condition of bacteria. The gas of phosphoreted hydrogen burns spontaneously under given conditions of moist air and then ignites the methane in the air which comes from the mouse holes.

专家组成功地模拟了罗家的&自燃&现象：含磷的矿物质在有细菌和具备还原性条件下分解成磷化氢气体，而磷化氢气体在一定潮湿的空气环境下自燃，继而引发空气中通过老鼠洞挥发出来的甲烷体燃烧。

A new desulfurization apprach for pulverized coal combustion is introduced in this paper; pulverized coal is first burn in a precombustion furnace under oxygen deficient condition (about 30% air needed in boiler is provided for precombustion), in precombustion moust of sulfur in coal is decomposed and oxidized, and evolved, the sulfur evolved is trapped in a desulfurizing fluidized bed by calsuim, and then the char and gas are introduced to the boiler furnace for complete combustion.

本文提出了一种煤粉燃烧脱硫新方案，利用煤中硫优先氧化分解释出的原理，用少量的空气（大略为锅炉实际空气用量的30％），在一前置燃烧室中，使煤粉中硫的绝大部分被分解氧化，释放出来，释放出来的硫在脱硫流化床中被石灰脱硫剂脱除，未燃烧的炭粒与烟气再吹进锅炉膛中完全燃烧。

We sample from indoor air using silonite coated canisters, preconcentrate low level samples utilizing three stages focuser,analyze VOC in indoor air with GC/MS equipment.
