The practice and experiments for many years have proved that the calibration of the gravimeter varies with temperature and has great effect on observed values. So it is necessary to find the temperature coefficent of the calibration and to correct the calibration of the observation datao。In this article, the calibration of all gravity data in Bejing, Tianjin and Tangshan regions has is corrected in another way. After the correction, the annual variation of gravity values at various stations is obviously eliminated, and has been calculated pre-earthquake gravity anomaly inTangshan. From April, 1974 to March, 1976, the cumulative gravity increased by 1.30μgal and the short-term anomaly approached 200μgal。The obtained results show that. the pre-earthquake gravity variation may bt due to the density anomaly at deep levels of the earth's crust。

多年来的工作实践及实验证明了重力仪格值随温度变化而改变,而且对观测值的影响极大,以致造成虚假异常。本文对京津唐地区重力资料进行格值改算,再计算唐山地震前,唐山测点自74年4月至76年3月累积重力上升了130微伽,由76年3月到7月短期异常近200微伽。根据异常范围、形态、量值计算震前在莫氏界面断裂处有一个密度异常区。

The catalytic system Sc~(3+)-NH_4Cl-Cupferron (Cup)-diphenylguanidine (DPG) suggested by Yao et al gives a sensitive derivative wave in single sweep polarograph. The linear relationship between the wave hights Hw and the conoentration of Sc~(3+) in the range of 10~(-7)~10~(-6)M has been used successfully in the ores analysis for Sc. We compared the waves in single sweep polarograph with that in the de polarograph and applied several electrochemical methods to investigate the mechanism of this wave. The experiments...

The catalytic system Sc~(3+)-NH_4Cl-Cupferron (Cup)-diphenylguanidine (DPG) suggested by Yao et al gives a sensitive derivative wave in single sweep polarograph. The linear relationship between the wave hights Hw and the conoentration of Sc~(3+) in the range of 10~(-7)~10~(-6)M has been used successfully in the ores analysis for Sc. We compared the waves in single sweep polarograph with that in the de polarograph and applied several electrochemical methods to investigate the mechanism of this wave. The experiments of electrooapillary curves, variation of the height of the mercury column and the time of the rest period before scanning, the temperature coefficent, cyclic voltammetry etc. indicated that the wave is adsorptive complex in nature and the ligand-Cupferron in the complex is catalytically reduced but not the cation Sc~(3+), therefore we call such catalytic wave as "adsorptive-complex wave". By applying the equation derived in our previous work, the composition of the adsorptive complex Sc~(3+): Cl~-: Cup: DPG is determined to be 1:2:1:1 with the conditional stability constant ;β=1.22×10~7 and the structural formula The electrode processes are described with the following steps: (1) complex formation of Sc~(3+) with Cup and DPG; (2) adsorption of the complex on the surface of the electrode; (3) dissociation of the complex and the reduction of Cup on the surface of the electrode: (4) repeat of the steps 1 to 3 to yield the adsorptive-complex catalytic wave.
