The residual gas pressure in an electron tube can be measured when the tube itself is operated as a hot cathode ionization gauge.Usually,its sensitivity K is determined by the method of gauge calibration.In this paper,author try to determine the sensitivity K by ca- lculation.The formulae for this purpose have be found out,and are used for both plate and cylindrical electrode systems.

把电子管接成热阴极电离计的工作形式，用来测量管内残气压强时，其灵敏度如何计算的问题在本文中作了讨论，给出了平板形电极系统和圆柱形电极系统的灵敏度解析式，对式中各量的计算作了详细介绍；并指出四极管中电子在电离区的平均渡越次数的表示式与三极管中的完全不同。

At the close of the war this problem will at once become acute and will involve finding means of taking care, not only of the millions of soldiers and sailors, but also of workers in munition factories and others wlhose occupations have been diverted from their normal course.

Some scientists now say GMT should be replaced by International Atomic Time — computed outside Paris — because new technologies have allowed atomic time to tick away with down-to-the-nanosecond accuracy.

现在有些科学家说，应该用在巴黎近郊1家科学机构）计算出来的「国际原子时间」取代「格林威治标准时间」，因新的技术能使原子时计达到以奈米秒计时的准确程度。

I.! y P,{7 v: R; O0 D INTRODUCTIONIn most of the previous studies like [1-3], the effect of SRS in DWDM fiber opticsystems has been treated under various assumptions like undepleted pump approximation, wavelength independent fiber loss coefficient, triangular approximation of Raman gainprofile, negligible loss of energy whenever a short wavelength photon is transformed into a long wavelength photon (i.e., l i / l k ~ 1), equal power loading in all the wavelength channels and equal channel spacing.

P _ W/ I 在以往的绝大多数研究中，如[1-3]，人们都认为， SRS 在 DWDM 光纤系统中的影响是在诸多假设，如未衰减泵近似值，波长依赖光纤损耗系数，喇曼增益表的三角近似值，当短波光子被转变为长波光子时(i.e。， l i / l k ~ 1可忽略不计的能量损耗，各波长通道均等的动力负载以及均等的信道的频率间隔。
