一、半自动门坎值调节器由于本工区浅层反射能量过强,我们采用了在同一张记录上前后使用两个门坎值的办法加以解决(前段为低门坎值,后段为高门坎值)。根据本区T_4层在1.1～1.2秒,T_7、T_9在1.6秒以后的实际情况,把高低门坎值转换的时间控制在1.1～1.5秒之间。具体方法是:在公控中保留原有调节门坎的10K电位器不动,再另加一个10K电位器组成两个门坎调节系统。两者可分别调成低、高不同的门坎值,以实现浅层低灵敏度,中深层
First, the semi-automatic threshold value regulator As the area shallow reflection energy is too strong, we use the same record before and after the use of two threshold values to be resolved (the previous paragraph for the low threshold value, the latter part of the high threshold value). According to the T_4 layer in this area 1.1 ~ 1.2 seconds, T_7, T_9 after 1.6 seconds in the actual situation, the high and low threshold value conversion time control between 1.1 to 1.5 seconds. The specific method is: retain the original regulation in the public control of the 10K potentiometer does not move, plus another 10K potentiometer composed of two threshold regulating system. The two can be adjusted to low, high threshold different values in order to achieve shallow low sensitivity, the middle and deep
