Both sectorphotometer and microphotometer analyses were carried out on the Hg spectrum transmitted by papers popularly used as window materials in Chinese homes. The intensity distribution of transmitted radiation, after normal incidence, through samples of nine different kinds of paper have been studied, and the total transmission calculated for various wavelengths.

以水银灯为光源,正射於纸上,其透射部份,用分光摄影法定量。以分圆光度计(Sectorphotometer)及显微光度计(microphotometer)量出九种窗户纸之紫外线透射性。并实验各种纸之断强度及其纤维之构造等,俾得相当之评价。 通常窗户纸对於具有最高生理效用之紫外线(波长2967A.U.)之透射量可居百分之十九至四十一;我国南部之壳片窗亦可透射百分之二十。至於玻璃窗,其透射量则等於零。外国虽有特备之玻璃能透射百分之二十至八十之此种紫外线,但其价值殊昂,不能使其遍普应用,可见两者反不若我国之窗户纸为佳矣。 窗户纸中以平粉连纸透紫外线最多,如将纸上桐油,则可视线及紫外线之透射力,皆有可观之增加,同时亦可去潮湿以致易破之影响。倘以普通之豆油油之,则其易於变黄,并减低其紫外线透射力,甚不适宜也。 如欲得较完全之讨论,请参考陈尚义之硕士论文,现存於燕京大学图书馆。

Chang Shan, the subterranean portion of Dichroa febrifuga Lour. (family Hydrangeaceae), and Shu Chi, the leafy tops of the same plant, have been used in Chinese medicine more than two thousand years, but their antimalarial action has been scientifically proved and constituents investigated only in recent years. A brief account of their history, botanical source, plant habit, cultiva-tion and collection and a detailed description of their sensory, macroscopical and microscopical characters are given. The important diagnostic features of Chang Shan are:-vessels with long oblique end-plates having well-marked scalariform perforations and often containing tyloses; septate xylem-fibres; idioblasts containing bundles of acicular crystals embedded in mucilage; thick-walled pericyclic fibres; the deep-seated origin of the cork. A well-marked medullary sheath of thick-walled, lignified and pitted parenchyma occurs in the pith of both the stem and rhizome. The important diagnostic features of Shu Chi are:-thick-walled, warty, unicellular trichomes; paracytic (rubiaceous) stomata; epidermal cells with pitted anticlinal walls and finely striated cuticle; water-pores in the teeth of the leaf; idioblasts with bundles of acicular crystals em-bedded in mucilage; droplets of fixed oil in most of the cells of the leaf; thick-walled pericyclic fibers from the stem as well as deep-seated cork and characteristic vessels as seen in the subterranean organs. The significance of some of the microscopical findings as a further illustration of the connexion between anatomy and taxonomy is also discussed.

In order to determine the workability of cast iron with spheroidal graphite,the following tests have been conducted on this material in the as-cast and annealed condition:tensile tests,compression tests,Charpy impact tests,impacttensile tests,twisting tests,upsetting tests under the drop hammer and small-scaledrolling tests.Results from these tests show that the best hot-working temperature rangeof this material varies somewhat with the stress system applied and the speed ofworking,and in general lies between 700° and 1100℃.Within this temperaturerange,the maximum amount of working permissible for a single working operationvaries considerably with the stress system applied.Under tensile stresses,thismaximum amount of working lies between 28 and 57.6%;under predominentlycompressive stresses,it lies between 58.5 and 72.9%;while in the small-scaledrolling tests,the maximum reduction in thickness permissible for a single passlies between 38.6 and 44.3%.The maximum amount of working permissible is alsoaffected by the speed of working,being greater at lower speeds.Tests on industrial scale show that the upsetting and small-scaled rollingtests give results nearest to those from industrial tests.Charpy impact tests,impacttensile tests,upsetting tests and small-scaled rolling tests show more prominentlythe best hot-working temperature range than the other tests conducted.Results of the present research also indicate that cast iron with spheroidal graphitehas a higher strength and workability when subjected to compressive stresses thanto tensile stresses,that a brittle temperature range has been recorded between200° and 650℃,which varies with the speed of test.Judging from the variationof the resistance to deformation with the change of temperature and the speedeffect,this phenomenon is associated with blue brittleness.
