Through the use of approximate expessions in the form of quadratic equations for the sum as well as the difference of principal stresses along any definite vertical line in foundation soil subjected to triangular and trapezoidal loading due to earth embankments. the author has derived formulas for critical load corresponding to the condition that plastic zone developed it tangential to the vertical line under consideration. Based on studies of the developed plastic zones in the foundation soil due to such a triangular and trapezoidal loading. it is proposed, that the criterion for determining the critical load on the foundation roil is that the developed plastic zone is tangential to a vertical line at one quater base width from the center line. Special considerations are given to the cases for convenient soil as well at for saturated clay of zero degree of consolidation. Charts convenient for pratical use are also prepared. Finally, numerical examples are presented which show that the proposed formulas are quite in conformity with field observations in engineering practice.

This is one of a series of reports on study of tandem-propeller performance. The report describes the influence of some important parameters of the tandempro-peller on their performance, such parameters including axial spacing ratio, angular spacing, diameter difference between fore and after propellers, pitch distribution of fore and after propellers and its pitch match each other, blade outline and shape of blade sections, etc.The performance charts of two sets of tandem-propeller CLB 4-40-2 and CLB4-55-2 are given. And further, the block diagram for design tandem-propeller with charts using digital computer is given. According to the test results, the comparison of the tandem-propeller with the single conventional B-series propeller of nearly the same disc ratio has shown that, under the condition of optimum diameter themselves and Bp≥4, the efficiency of tandempropeller is a little higher than the conventional propeller and the optimum diameter may be decreased by morethan 4%, however, under the condition of restricted diameter and Bp≥4, the efficiency of tandem-propeller is higher than conventional one and its increment of efficiency is increased when the Taylor's power coefficient Bp increased or Taylor' s speed coefficient 6 decreased.

本文是作者关于串列螺旋桨方面的研究报告之一,它探讨了串列浆的重要参数(包括桨距比、叶错角以及前后桨的直径、螺距分布和配合、叶型和叶轮廓等)对其性能的影响,发表了两组串列螺旋桨系列试验图谱CLB4-40-2和CLB4-55-2,并给出了用图谱方法设计串列螺旋桨的框图。 对于直径不受限制的情况:在(1/2)B_p≥4时,串列桨的效率比相近盘面比的普通桨略高,最佳直径减少4%以上;对于直径受限制的情况:在(1/2)B_p≥4时,串列桨效率皆较相近盘面比的普通单桨为高,其效率增加量随功率系数(2/1)B_p的增大或直径系数δ的减小而增加。

The effect of small amount of dichloethane in the feed was examined and the suitability of the proposed equations to the feed containing 7.7% carbon dioxide was also confirmed....

On studying the Kinetics of ethylene oxidation reaction with feed containing 4.0-4.4% ethylene and 6.0~6.7% oxygen at 190—230℃ and 10 atm on the YL—016 silver containing catalyst mentioned in the preceding paper, the following reaction scheme was proposed. and the individual rate equations with their kinetic parameters was determined. The effect of small amount of dichloethane in the feed was examined and the suitability of the proposed equations to the feed containing 7.7% carbon dioxide was also confirmed. The results of this study may be used for the scale-up of chemical reactors.
