Measurement of the intensity of total scattering of x-rays by a number of polyatomic gases was made for scattering angles between 15° and 130 ° using an ionization method of recording the scattered intensity. Balanced filters of ZrO2, and SrO were used to separate the MoKa rays and Soller slits were placed in front of the ionization chamber to obtain a definite scattering angle. The gases studied are CL2, CO2, N2O, H2S, CC14 and CHCl3. In each case the absolute values of the scattered intensity were determined...

Measurement of the intensity of total scattering of x-rays by a number of polyatomic gases was made for scattering angles between 15° and 130 ° using an ionization method of recording the scattered intensity. Balanced filters of ZrO2, and SrO were used to separate the MoKa rays and Soller slits were placed in front of the ionization chamber to obtain a definite scattering angle. The gases studied are CL2, CO2, N2O, H2S, CC14 and CHCl3. In each case the absolute values of the scattered intensity were determined by comparison with the scattering from oxygen, the results of Wollan for the latter gas being taken as correct. The experimental results are actually compared with Woo's theory of the scattering of x-rays by polyatomic gases and the agreement seems to be satisfactory.

吴有训氏最近对于多原子气体散射线之理论,曾作详尽的探讨。吴氏得到一个公式,表示由多原子气体所散射之强度,其中一部为相干的散射,另一部为不相干的散射。 以前关于多原子气体散射X-线之实验,为数甚少,且为定性的结果。最近美人Wollan,对于由O_2及N_2(双原子气体)所散射钼的K_3α线之强度,曾作绝对的度量。Wollan的结果,与吴有训氏的理论,甚属相符。本篇目的,在测定由 Cl_2,CO_2,N_2O,H_2S,CCl_4及 CHCl六种气体所散射X-线之强度,每一实验,均与由0_2者互相比较,根据Wollan的结果,每种气体所散射之绝对强度,皆一一量得。所用之入射X-线为钼之Kα线,系藉Ross的平衡过滤法分出。强度之测量,系用一游离方法。散射角度的范围,自15度至130度。每种气体的实验结果,均与吴氏的理论,互相比较,证明理论与实验,甚属相符。在计算时,原子的“构造因数”,系由Hartree的方法算得,一分子中两原子的相隔距离,则由带光谱的结果推得。

In this paper a modified method is recommended for the determination of rubber hydrocarbon present in kok-saghyz rubber by means of bromination.This method is rapid and accurate.A conversion factor of 0.298 is obtained for con- verting rubber bromide content to rubber hydrocarbon content for kok-saghyz rubber.The conversion factor agrees well with the theoretical value.

本文报告了用重量溴化法测定青橡胶草生胶中橡胶烃的各种适宜条件,并求得了由溴化橡胶换算为橡胶烃的换算因数为0.298。三氯甲烷可用来防止溴化橡胶的结膜,同时并可防止溴与橡胶的置换反应。每10毫升橡胶液应加溴化溶液2毫升。溴化反应可在常温进行。三氯醋酸可使橡胶容易溶解,对分析结果无显著影响,用或不用均可。溴化法无论在分析时间上和精确度上,均较直接抽提法和间接测定法为优。

在电力线路上使用的载波频带中,除带滤波器式宽频带阻波器中电感的分布电容必须加以考虑,在设计时,L_1的分布电容可以并入并联的电容C_1中,而表示L_2的分布电容的自然谐振频率f0成为设计参数之一。为了保证在给定截止频率f2′和f_1′范围内输入阻抗大于KR,采用了和f2′与f1′稍有差别的设计用的截止频率f2和f1,按照f2和f1进行设计,就可使在f2′和f1′时的输入阻抗电阻部分等于R。f2—f1比f2′—f1大些。这两个频率可以从给定的f2′、f1′、f0′和电感电容的功率因数中求出。f0一般可以采用在1.5f2′和2f2′间的数值为宜,大于2f2′的f0会使扼阻频带中的颠值阻抗降抵,小于1.5f2′f的f0会使扼阻频带外的输入阻抗降低得太快。末端电阻KR中的K以采用1和0.95间的数值为宜,如果K小于0.95,扼阻频率带中的最低阻抗KR变得太小;如果K大于1,在给定的f2′—f1′情况下所需频宽f2 f1变得大些,这就提高强流线圈的电感L_1,使所需采用的有色金属多些。
