一、简述基式仪是中长周期光记录地震仪,该仪器性能稳定,图象清晰,数据可靠。为进一步提高观测质量及对外资料交换水平,我们对记录器上的固定记录相纸接头的有机玻璃压条进行了革新试验,自79年11月9日改装后,对40天来的记录进行观察,消除了有机玻璃压条边缘造成记录图上的类似时分号的白点影响,同时没有发生图纸松脱,记录器停走之类的事故,试验已获得成功。现将无压条记录法的革新意义、想法及做法等介绍如下,供同志们参
First, a brief description The basic type instrument is a medium-long period optical recording seismometer, the instrument performance is stable, the image is clear, the data is reliable. In order to further improve the quality of observations and the level of exchange of information with foreign countries, we conducted a revolutionary experiment on the plexiglass bead of the fixed recording paper connector on the recorder. After 40 days of refitting on November 9, 79, we observed the records of 40 days. Elimination of the effect of the white point on the record similar to the time-sign caused by the edge of the plexiglass bead and the successful conclusion of an accident such as loose drawing and logger stop. The innovative meaning, ideas and practices of no-pressure recording method are as follows for reference
