n-Butyl benzoate is proposed as a new medium for the falling drop method of determination of deuterium oxide in a sample of dilute heavy water. It is suitable for analysis in the concentration range of 0—10.5 mol% D_2O at working temperatures 22—33.5℃. A mixed medium composed of n-butyl and iso-butyl benzoate in about 1:1 ratio can be applied to analysis for 0—7 mol% D_2O at working temperatures 21.5—26.5℃. iso-Butyl benzoate can be used at 20.5℃ for analysing 0—4 mol% D_2O. Calibration curves for these media...

n-Butyl benzoate is proposed as a new medium for the falling drop method of determination of deuterium oxide in a sample of dilute heavy water. It is suitable for analysis in the concentration range of 0—10.5 mol% D_2O at working temperatures 22—33.5℃. A mixed medium composed of n-butyl and iso-butyl benzoate in about 1:1 ratio can be applied to analysis for 0—7 mol% D_2O at working temperatures 21.5—26.5℃. iso-Butyl benzoate can be used at 20.5℃ for analysing 0—4 mol% D_2O. Calibration curves for these media are shown in Fig. 9 and 10~* (in Chinese text). The relative error of determination is about 0.1%.These media are each subjected to a 500-drop stability test. They possess different periods of adaptation prior to reaching a stable state (Fig. 3). Such a "prior-period" effect can be eliminated through previously saturating the medium with water (compare the third and fourth curves in Fig. 3).ο-Fluorotoluene is a stable medium, a result differing from the observations of Krell et al., wh onsider it to be "very unstable".The varying amounts of the residual water on the tip of a micropipet in the form of a spherical segment as a result of releasing previous drops with different sizes are studied. Such variations cause errors in timing the fall of the next drop, which is intended to possess an exactly measured volume. Such a "residual-liquid" effect can be minimized by the design of a fine tip, say 1.4 mm in outer diameter. In this way, the next drops, say 8.00 μl in size, fall with speeds constant within±0.1%.

This paper presents the results of the remanent magnetic stability test of some orientated Lower Sinian sandstone samples collected in Hsiuning district, Anhwei province. Demagnetization procedure has been carried out on all specimens by alternating magnetic field, and the results show that the natural remanent magnetism of the formation is stable. The direction of the intensity of the mean remanent magnetism is determined as D_r=311° and I_r=76°. Thus, the position of the palaeomagnetic north pole at this age is inferred to be 90°E and 45°N, and the former latitude of the sampling site is 90°-p=63°. On the basis of the results some suggestion on the climatic condition in Hsiuning district during early Sinian period is made.

This paper gives the result of a special study of the stability sliding in rock mass on the right abutment of certain reservoir. The breaking face in landslide mass is assumed to be inclined. The ultimate equilibrium of wedge shaped mass is used to calculate the position of breaking face and the sliding force. Through the present calculation of rock mass stability, it is considered that the angle 6 between the force acting on the breaking face and the normal direction of the face would be more appropriate to take the angle of internal friction of rock. Finally, the method of equatorial horizon projection is used to analyze and calculate the sliding force and the resisting force in space. Based upon the, results of present calculation, appropriate measures have been proposed, and accordingly are adopted by the engineering projects. To the further verification of these assumptions and results of calculation, plane model stability tests of rock mass consisting of blocks, which stipulated the engineering geological condition of this project have been made. It is fully proved from the test results that the proposed assumptions and method of calculation are close to reality.

此文是某水库右坝肩岩体稳定专题工作成果;提出了滑坡体内破裂面是倾斜的假定,并用楔形体极限平衡计算破裂面位置及滑动力。通过对目前稳定岩体的计算,认为内破裂面作用力与法线夹角δ值取岩石内摩擦角比较合适。最后运用赤平极射投影进行空间滑动力与阻抗的分析计算。根据计算成果,提出了相应的处理措施,为生产单位采用。 在工地做了符合本工程地质情况的块状岩体稳定平面实验,试验成果证实了提出的假定和计算方法是符合实际的。
