Atmospheric processes

The replacement of SF6 by refrigerant is under development. For example, R143a by AMC and FK by 3M Co. used as protection gas are both classified as HFC with short atmospheric lifetime and are easily to be decomposed into hydrofluoric acid, carbon monoxide and fluoric carbon monoxide at room temperature.

目前发展中的替代性保护气体以冷媒类为主，如澳洲AMC所采用的R134a及美国3M公司所开发的FK气体，两者都属於氟氢碳化合物，不过其半衰期短，即使在常温下，仍极易分解成氢氟酸、CO、COF2等，其中氢氟酸为有害物质，但因含量很少，且在高温下易与镁液反应，故对人体的为害很小。

Fluoroform is one of the most significant stable molecules of greenhouse gas in atmospheric physics. The Global Warming Potential of this molecule has risen to prominence. It has been of great interest to physicists and chemists.

CHF_3是大气物理温室气体中最重要的分子之一，它的全球变暖潜能非常突出，受到物理学家和化学家的高度重视。

A series of reactions may occur when the nitrous acid and naphthalene inside the atmospheric aqueous phases is exposed to sunlight. This article devotes to investigating from a microscopic angle the reaction mechanism and kinetics of this system using laser flash photolysis technique with an excitation wavelength of 355nm. The main research results are listed as below:(1) The OH quantum yield FOH for the photolysis of HNO2 in the aqueous phase was determined to be 0.234 and the absorption spectrum of OH radical was recorded as well.

本文以激光闪光光解为主要研究手段，考察了大气液滴中的HNO2及HNO2+萘体系经355nm紫外光照射后发生的微观反应及其机理，结果表明：(1)液滴中的HNO2经355nm光照产生OH自由基的量子产额为FOH=0.234；以瞬态技术记录了水相中的OH自由基的吸收光谱。

The effects of anti fatigue and oxygen deficient durable under normal atmospheric pressure of Fomes Officinalis Ames were observed in the fatigue test and oxygen deficient durable experiment in mice.

本研究采用抗应激实验的方法，观察新疆药用层孔菌对小鼠抗疲劳能力以及耐常压缺氧能力的影响，比较给药组与对照组小鼠存活的时间，对测试结果的方差分析及多重比较表明，药用层孔菌具有很好的补益作用，能增加小鼠的抗应激能力，同样条件下能延长小鼠的存活时

Kitazato indicated that he was surprised by the abundance of foraminifera in the deep water because the pressure there is 1100 times greater than normal atmospheric pressure at the surface.

Hiroshi Kitazato表示，他对那儿有如此多的有孔虫感到吃惊。由于水的深度，那儿的压力大约是一般大气压的1100倍。

Pure DCP was obtained by fractional distillation in an atmospheric column with 20 theoretical stages.

This study shows that the occurrence of these seiches is likely the result of coupling and resonance between atmospheric perturbation and free mode oscillation of the bay, which has the oscillation of off-shore surface wave as an intermediate media.

研究认为，假潮的发生很可能是大气扰动通过外海表面波作为中间机制，与港湾自由态振动之间产生耦合共振的结果。
