Upper air visibility and vertical visibility are different from horizontal far distance visibility. They have special signifigance in aviation.In this paper the atmospheric extinction coefficieat, the upper air visibility and vertical visibility are calculated by observing the polit balloons and radiosonde balloons.The principle of visibility instrument is used that is making use of optical wedge, photoelectric cell etc, to carry out the measurement. Foitzik 1947, Duntley 1948, and some other scientists have disscnsed the problem of vertical visibility. Their method is to carry out the calculation with given atmospheric extinction coefficient, while in practical application this calculation is the second step, what we need to find out first is the atmospheric extinction coefficient. In Duntley's paper, he assumes that within the limit of discussion, the intensity of sky light is constant. But this can only be true within a very thin layer of atmosphere, as to the atmosphere which is kilometres thick, it has to consider the attenuation of light by the atmosphere. Furthermore he assumes that the anisotropy of atmosphere's scattering function is invariant with height and then it is considered as a molecular atmosphere. But this has been proved by several authors in theory and in experiment to be not true, especially in the lower atmosphere. Certainly, Duntley's calculation is not accurate and is limited in application.A correction has been given to the above mentioned assumptions in this paper. Finally, the problem of light of source visibility in night and some other materials on observation are being discussed.

The present paper reports investigations of thin layer chromatography for the identification of ergot alkaloids, using alumina without binder. As dictated by the physico-chemical properties of ergot alkaloids and the usual characteristics of thin layer chromatography, studies on factors influencing R_f values and shape of spots of ergometrine, ergotamine, and ergotoxine have been carried out. Good separation was obtained with acidic, neutral as well as weakly basic alumina. Alumina with particle sizes of 120—160, 160—200 and below 200 mesh were compared, the best result being obtained with the last size, producing round and sharp spots. Mixtures with various ratios of petroleum ether-benzene-absolute alcohol and of benzene-chloroformabsolute alcohol were used and mixture of benzene-absolute alcohol (10:0.5) was found to be the best, with R_f values 0.10, 0.33 and 0.50 for ergometrine, ergotamine, and ergotoxine respectively. The composition of this solvent mixture is rather simple and amenable to ready recovery. The angle of inclination made by the plate had no great influence, although the most suitable was found to be between 8—16°. "Edge effect" may be avoided by tightly covering the container for 10 minutes to assure saturation with the solvent vapours before immersing the lower end of the plate. According to these results, a thin layer chromatographic method for the identification of ergot alkaloids has been proposed, which gave identical results as paper chromatography when tested with eight ergot samples.

本文研究了影响麦角新碱、麦角胺和麦角毒碱的氧化铝薄层层离的各种因素.实验结果表明,酸性、中性和弱碱性氧化铝均能使三种麦角生物碱分离.氧化铝细度以小于200号筛的层离效果最好,莹光点圆而集中.苯-无水乙醇(10:0.5)是较为理想的推进剂,不仅分离效果好,而且其组成简单,容易处理和回收.层离板的斜度对层离效果影响不大,但以8—16°角较合适.层离槽放入溶剂后,必须先密闭放置10分钟,才能进行层离,否则容易产生边缘效应.根据以上研究桔果,制订了鉴定麦角中三种主要生物碱的方法.

本文讨论了:(1)用阳极氧化法在硅片表面去层的技术;(2)用四探针测量扩散层面电导的方法;(3)用阳极氧化去层及四探针测量面电导方法求得扩散层精细杂质分布。 文中着重讨论了实验技术中的实际问题,如如何在阳极氧化过程中取得精细而均匀的去层(300—1500);如何控制及测量去层厚度;测量面电导及杂质分布时的误差来源及减小误差的措施。 以典型的磷在硅中扩散的杂质分布测量为例:扩散深度为4.9μm,测量间距为400—1600,面电导测量误差估计小于3%,杂质分布误差估计小于20%。简单地提出了一些测量中尚待进一步解决的问题。
