A method for preparing the high acid-consuming-capacity dried aluminium hydroxide powder by the use of alum and soda or other alkali substance as raw material is described. 1) The best results were obtained by using soda as raw material for preparing the alkali solution. 2) The alum solution was added to the alkali solution until pH 5.5-6.5 was reached. 3) The sulfate was removed almost completely by washing with potassium bicarbonate solution(0.4%) before drying. 4) The aluminium hydroxide gel can be dried completely under 100-105℃(ca. 6 hrs.) without influencing the antacid activity. 5) The highest acid-consuming-capacity of the dried powder of aluminium hydroxide gel(free from any free alkali) was determined to be 315.9 ml, i.e. one gram dried sample will neutralize 315.9ml 0.1N HCl.

High percentage of chlamydospore germination of Neovossia horrida (Tak.)P.& K.with abundant basidiospore production was obtained by placing moistenedspores in a Petri dish with limited supply of water,the dish-cover being inkedblue to insure a favordable light condition.Moistened spores applied on the sur-face of kernels of a growing rice head enclosed in a paraffin paper bag was alsofound to germinate by producing a very short basidium and a large number ofbasidiospores.It is,therefore,concluded that not only light but also oxygen isrequired for normal germination of the spores of the rice kernel smut. Results of a series of inoculation experiments conclusively show that thefungus infects rice kernels during the milky dough stage.Basidiospore inoculationgives higher percentage of infection than chlamydospore inoculation. Field observation indicates that the incidence of high percentage of infectionis coincident with the excessive application of nitrogenous fertilizer.Fluctuationof the amount of infection from year to year is probably determined chiefly by theduration of high moisture period from heading to dough stage.There are someevidences of varietal difference in the susceptibility of rice to the kernel smut.

The absorption spectra of cadmium sulphide single crystals were observed with natural light and polarized light, one piece of the crystals having a thickness of about 0.1 mm and another about 0.05 mm. At room and liquid air temperatures, the absorption spectra observed with natural light indicate that the wavelength of the long wavelength limit of Cd S depends upon the thickness and the temperature of the crystals. A change of the wavelength of the absorption edge which depended upon the orientation of the electric vector of the polarized light produced by a polaroid plate placed between the crystal and the slit of the spectrograph was observed.

利用CdS单晶体,一块约厚0.1毫米,另一块约厚0.05毫米,观察它们在天然光及偏振光下的吸收光谱。在室温及液态空气温度下,天然光的吸收指示CdS晶体长波吸收边波长随厚度及温度而改变。在光谱仪狭缝前放一偏振片观察到长波吸收边波长随晶体C轴与偏振光电矢量间介角的改变。 在液态空气温度下观察CdS晶体对偏振光的吸收情况,发现在晶体本徵吸收边出现由七条强而锐的谱线组成的一个类氢光谱系。 测量结果发现每条谱线的波数满足下列公式: v_k=20270-11754/k~2(厘米)~(-1),式内k=3,4,5,…9;k=2的线未在光谱中发现。从此式推出的CdS晶体能级的系限加以温度较正为2.41电子伏,与前人用其他方法所得2.42电子伏是很相近的。激子的等价质量与电子质量之比为4.3。 CdS晶体与ZnS晶体结构相似,常数数值相近,由此可以猜测CdS晶体能级的满带可能是属于S-离子。所观察到的激子光谱类氢系可能是S-离子的激发态。
