Uterine spontaneous contraction and the irregular responses of uteri towards same doses of pituitary extract were very often encountered in the uterus method for pituitary bioassay.The rate of successful experiments was variable.It was found that uteri obtained from rats in proestrus stage gave much better results than those in either diestrus or estrus.Experiments employing ovarietomised rats treated or untreated with hexoestrol dipropionate also showed that uteri from rats in artificial diestrus gave disappointing results but uteri in artificial proestrus were as good as those in normal proestrus(Table Ⅰ). Table Ⅰ.Rate of Successful Experiments of Pituitary Assay Using Rat Uterus Method on Uteri in Different Stages of Estrous Cycle Rats(120—230g) Groups No.of Animals Used Rate of Successful Experiments Normal Diestrus 10 2/10 Proestrus 10 10/10 Estrus 10 6/10 Ovariectomised Treated with Hexoestrol dipropionate(artificial proestrus) 5 5/5 Untreated(artificial diestrus) 5 0/5 Reports on using diestrus uteri in rat uterus method for pituitary assay in previous literature are therefore proved to be not well founded. The possibility and problems involved in employing artificial proestrus uteri in pituitary assay are discussed.

1.利用大白鼠子宫法来测定脑垂体后叶时,以采用在前情期的动物可以得到最高的成功率.研究中所用的十个动物得到完全成功的结果,在经常检定工作中亦证实了此点.因此对大白鼠法提供了通过阴道涂片选择动物的改进方法.2.实验结果否定了关于过去文献介绍应用间情期动物的记载.3.讨论了雌性激素处理过的大白鼠(人工前情期)应用于脑垂体后叶检定的可能性,和可能影响检定结果的因素.

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。

In order to rectify the existing acoustic defects of the lecture hall of Wen-Yuan Building in our university, a series of acoustic measurements were carried out, and analysis and a scheme of reconstruction was proposed therefrom, After completing the alteration according to the new designs in the summer of 1956, the hearing conditions of the hall were found to be greatlly improved. The author pointed out, however, that due to the lack of experience in this kind of work and to the insufficiency of acoustic instruments, there are still certain defects, the remedy of which would require further research work. Ⅰ. Introduction Ⅱ. A general description and analysis of the lecture hall before alteration. Ⅲ. Analysis and improvement from the view of geometrical acoustics. Ⅳ. Reverberation time. Ⅴ. Sound intensity distribution after alteration. Ⅵ. Noise reduction. Ⅶ. Some unsolved defects and problems.

为改善本校文远楼大讲堂内的音质缺陷,我们曾进行了一系列的音质测定和分析工作,并作了改建设计。1956年暑改建完毕以后,基本上已能符合听讲的要求,听者一般都感到清晰和满意。由于声学仪器和实际经验的不足,工作中尚存在着一些缺点和问题,在本报告中亦一一提出,以待今后继续加以研究解决。Ⅰ.绪言。Ⅱ.现况介绍和分析。Ⅲ.从几何声学上加以分析和改进。Ⅳ.混响时间的改进。Ⅴ.改建后的声强分布。Ⅵ.降低噪声的措施。Ⅶ.工作中存在的问题和缺点。
