As regards environmental protection, WMO's Global Atmospheric Watch monitors the chemical composition of the atmosphere including greenhouse gases, the ozone layer and ultra-violet radiation, as well as long-range transport of pollutants, aerosols, reactive gases and radioactive isotopes.

在环境保护方面，WMO的全球大气监视网对包括温室气体在内的大气化学成分，臭氧层和紫外辐射以及污染物、气溶胶、再活化气体和辐射同位素的长期距离传输进行监测。

This thesis proposes a kind of soft firing technology , which combines interior ballistics with atmospheric pressure transmission theory , utilizing the energy of advancing primer ignition of piston promoting pill to counteract the counterforce of firing pill , utilizing unilateral valve on the piston to adjust automatically the gas pressures of two connected chamber in series in front and at the back of the piston, thus achieving the goal of reducing composition of forces of gun bore and increasing initial velocity of pill.

本论文提出一种软发射技术，是将气压传动理论和经典内弹道学相结合，利用活塞推动弹丸前冲击发的能量来抵消发射弹丸所产生的反作用力，利用活塞上的单向阀自动调节活塞前后两个串联药室的气体压力，从而达到减小炮膛合力和提高弹丸初速的目的。

The present ice ages are the most studied and best understood, particularly the last 400,000 years, since this is the period covered by ice cores that record atmospheric composition and proxies for temperature and ice volume.

Besides, the data of n observed at perigees are used to roughly estimate the altitudes of the turbopause Zt and their variations according the two distinct vertical distributions of atmospheric composition in low and upper atmospheres: the homogeneous mixing and the diffusive separation.

采用近地点上的n观测资料，根据大气数密度在低层内均匀混合和高层内扩散分离的不同垂直分布特征，粗略地估算出湍流层顶的高度Zt及其变化。

Experiments on gasification of Shenhua, Longkou and Datong coals in the rig with the agents of air and steam at atmospheric pressure and different operation conditions were carried out. The effects of operation condition, such as type of coal, coal feed rate, steam/coal ratio and air/coal ratio on gas composition, calorific value, carbon conversion and gasification efficiency are analyzed.
