与齿缝张开程度相当的液柱压力,是蒸气通过泡罩塔塔板压力降的主要组成之一。本文就空气-水系的实验,证实了前人提出的、根据孔口流出原理来计算齿缝张开程度与空气流速关系的理论公式;并得出孔口流出系数与Re准数间的函数关系,藉此可使该公式能普遍应用於常用操作条件的范围内。

Normal paraffins obtained from urea-adducts could be oxidized to alcohols only after they were free from residual aromatic hydrocarbons. Various factors influencing oxidation were examined: 1.Reducing the air supply instead of inert-gas dilution of air could get proper yield of alcohols; 2.Formation of alcohols was favored by raising reaction temperature; 3.Moderate increase of the quantity of boric acid accelerated the formation of alcohols; 4.Dehydration of boric acid before oxidation increased...

Normal paraffins obtained from urea-adducts could be oxidized to alcohols only after they were free from residual aromatic hydrocarbons. Various factors influencing oxidation were examined: 1.Reducing the air supply instead of inert-gas dilution of air could get proper yield of alcohols; 2.Formation of alcohols was favored by raising reaction temperature; 3.Moderate increase of the quantity of boric acid accelerated the formation of alcohols; 4.Dehydration of boric acid before oxidation increased the reaction-rate as well as the propor- tion of alcohols; 5.To prolong reaction time favored the formation of more acids than alcohols. Better conditions of oxidation were: temperature,200℃,air-flow,150 liter/kg·hr,and with boric acid anhydride as catalyst.

The paper begins with a theoretical analysis of potential flow for the two-di- mensional conduit inlet,and after the boundary curve of constant pressure is obtained, it is transformed to the case of axial symmetry.It is hoped that the pressure along the new boundary,be nearly constant.The method of transformation is mainly that for equal distance ratios(i.e.,distance divided by entrance width in the two-dimen- sional case and that divided by entrance diameter in the axially symmetrical case), area ratios(i.e.sectional area divided by entrance area in both cases)are equal. The pressure distribution along the curved wall of an axially symmetric inlet so obtained was calculated by the relaxation method,and that of another was measured from an air-flow model test.The results as given in Figures 10 and 13 of the paper show that although the pressure along the wall is not constant,the variation is not great.The paper finally suggests that as for to reduce the possibility of cavitation, the forms of the axially symmetric inlets given by Equations(5)and(6)of the paper may be considered as adequate for practical cngineering use,with the restriction that the value of k which appears in the two equations not be greater than 0.05,in order to prevent the possible separation of flow from the inlet wall.

文中给出了隧洞进水口曲线为等压的二元分析结果,然后将此二元进水口的曲线形式转变为轴对称进水口的曲面形式。所用的转变方法是:当 x/D=(x_1)/B时,d/D=(b/B)~(1/2),其中 d、x和 D 分别为轴对称进水口段中某断面的直径,由起始断面至该断面的距离和起始断面的直径;b、x 和 B 分别为相应二元情形的某断面的宽度,由起始断面至该断面的距离和起始断面的宽度。对用这种方法得到的一个轴对称进水口曲面上压力分布,进行了松弛法计算,还对另一个进行了气流模型试验。结果如文中图10及图13指明,曲面上压力虽然不是等值的,但变化不大。文中建议,就减蚀的意义而言,式(5)和式(6)所给轴对称进水口曲面的形式是可以考虑来作为实际工程上应用的,但为了避免可能发生水流从边壁上脱离的现象,式中 k 值应取小于或等于0.05。
