【摘要】 <正> 地震前,泉水、井水的温度变化已有较多报道。有人曾用热敏电阻或铂电阻温度传感器进行地热前兆观测,方法虽简便,但是灵敏度低,稳定性不够好。 我们于1982年研制成功了以石英晶体做测温传感器的SZW-1型数字式钻孔温度计,下面对该温度计的原理作一简单介绍。更多还原

【Abstract】 In this paper, the quartz thermometer which is used in seismological work is described. The digital linearization processor the authors have designed provides a solution to the problems of scattered and nonlinear characteristics of the domestic Y-cut quartz crystal, so that the automatic digital measurement of temperature with high accuracy,high resilusion and high stability within a wide temperature range from 0℃ to 100℃ is realized. The thermometer can be also used to observe the geothermal precursors, to accurately monitor environmental temperature and to measure temperature gradients.更多还原
