Normal sound absorption coefficients of some Chinese acoustical materials as measured by the tube method were tabulated and problem of conversion to random coefficients was discussed. Our results: most of the prefabricated units showed low absorption efficiency especially at low frequencies.

本报告首先列举用驻波分析法所测得的若干国产吸声材料——包括纤维板,木屑板,木丝板,玻璃绵砖,毛毡及棉絮等等——的声波垂直入射的吸声系数,并对于吸声系数的定义以及几种不同吸声系数间的转换问题也作了简单的讨论。测量结果指出:许多产品吸声效率都很低,特别是在低频。(某些产品作为“薄板吸声”来控制室内音质是可以的,但不宜当作多孔性材料来使用。某些厂家在广告中注以“隔声”和“隔热”等名词尤其是不恰当的。) 其次,对于(1)材料粉刷,涂漆,和穿孔的影响,(2)有效厚度和流阻的关系,以及(4)薄板,薄的多孔性材料,和穿孔吸声结构的吸声性能等,都作了测量,并附以必要的理论说明。对于穿孔吸声结构阐述较多,主要是由于这种吸声结构应用的范围可以很广泛而目前国内使用得还远不够多。 最后作者们根据所测定的结果,对国内吸声材料的使用和制造提出了一些初步的建议。

The effect of the anomalous magnetic moment of the nucleon on the value of the internal conversion coefficient is investigated.The parts played by the sealer and tho longitudinal photons in the process of the internal conversion are first discussed. The retarded interaction between the charged particles with anomalous magnetic moment is derived by the correspondence method. The results obtained is then verified by the quantum electrodynamical treatment. The retarded interaction thus obtained is then applied to the calculation of the internal conversion coefficient. It turns out, that the anomalous magnetic moment of the nucleon has negligible influence upon the coefficient of the magnetic conversion and the coefficient of the electric conversion induced by the proton transition. However, the anomalous magnetic moment of the nucleon does cause considerable modification of the coefficient of the electric conversion induced by tho neutron transition, contrary io the conclusion arrived a,t by various authors~[4,6]. The problem of the gauge transformation is discussed and the errors contained in the treatment given by these authors are pointed out.

本文讨论核子的反常磁矩对于内转换系数数值的影响。首先讨论了纵光子和标量光子在内转换过程中所起的作用。然后用对应的方法推导出具有反常磁矩的荷电粒子之间的推迟相互作用。又用量子电动力学推导推迟相互作用,得到完全相同的结果。这一推迟相互作用被用来计算内转换系数。结果指出:核子的反常磁矩对于磁多极内转换系数以及由于质子跃迁导致的电多极内转换系数的影响微不足道。但是和某些作者的结论相反,核子的反常磁矩对于由于中子跃迁而导致的电多极内转换系数产生显著的影响。讨论了计算中所用的规范问题,从而指出这些作者处理本问题时所引入的错误。
