现在通用的几种电子笔绘地震仪中,拾震器的标定问题以及它的误差问题,值得讨论研究。本文就此发表些粗浅意见,不当之处,敬请批评指正。将全套电子笔绘地震仪分成两部分来标定这就是通常的“分段标定法”。此法中,摆(拾震器)作为一部分单独标定。摆在使用时常需要标定的常数有周期T_1,空气(机械)阻尼D_(10)电流常数P_1(或电动常数G_1),中肯电阻a_1,电压灵敏度S_(10)等。上述常数中较重要也较难标定的要算P_1,G_1和a_1了。下面就谈谈它们的标定方法和误差问题,从而涉及到方法的选择问题。
Now several common electronic pen-painted seismograph, the calibration of the pickup and its error problems, it is worth discussing. This article published some superficial opinions, inappropriate, please correct me criticism. The full set of electronic pen-painted seismograph is divided into two parts to be calibrated This is the usual “staging method.” In this method, the pendulum (pickup) is calibrated separately as a part. The constants to be calibrated often have period T_1, air (mechanical) damping D_ (10) current constant P_1 (or electric constant G_1), medium resistance a_1, voltage sensitivity S_ (10) and so on. Among the above constants, the more important and the more difficult to calibrate are P_1, G_1 and a_1. Now talk about their calibration methods and error problems, which involves the choice of methods.
