The conception of "inversion curve" is usually introduced in the discussion of the temperature effect for adiabatic throttling process of gases. However, the general features of an inversion curve are rarely discussed. It is the purpose of this paper to clarify the incorrect statements in certain text-books. As the results of such an analysis, the following conclusions are presented: 1. It is the following pair of equations that serves as the equation of an inversion curve: It is not exact to consider that the second equation of this pair of equations itself is the very equation of tile inversion curve. 2. The inversion temperature cannot be simply represented by v ( ). 3. The higher inversion temperature decreases with tile increase of pressure, while the lower inversion temperature increases with the increase of pressure. The higher inversion temperature and the lower inversion temperature must be treated seperately. 4. It is not correct to say that the lower inversion temperatures are all in the liquid region.

讨论气体绝热节流过程中的温度效应时,一般要引入“转变曲线”这一概念。但关于转变曲线的实质。在一般热力学书中则讨论得较少,并因此而使一些有失概念他得不到完善的理解。本文分析了转交曲线的实质,讨论了转交曲线的方程式,给出了转变曲线在p-v-T空间内的形状,并就转变温度随压力而改变的情况,澄清了由某些书中的错误阐述所引起的疑问。

An experimental observation on stimulated emission of radiation at liquid nitrogen temperature is reported. The paramagnetic material is synthetic ruby with about 0.1% chromium in Al2O3. The pumping frequency lies at X-band range while the signal freqe-ncy is set at S-band. The dependence of saturation factor on pumping power is measured . The negative temperatuve effect on population distribution is observeb with a pumping power about 10-2 Watt. The ratio of population inversion is 0.44.

In this paper the lifetime of the terminal energy level has been considered in the rate equations of the fast Q-Switched four-level laser. Computer solutions are pre-sented. The effects of the terminal energy level lifetime, the initial inversion popula-tion density, the stimulated emission cross-section and the cavity length on the behavior of giant laser pulses and multipulses have been studied in detail. The optimization and miniaturization of electro-optically Q-Switched lasers are discussed.
