目前各野外模拟小队所用的大线都是30芯50米管一道或100米管两道。插头为28脚两排,除了24芯用于排列和2芯用于通讯道外,还剩下4芯2脚没有用上。只要把大线焊接稍为变动一下(原燃料化学工业部六四六厂一九七二年八月出版的《地震勘探基本知识》放线技术部分已有介绍——本刊注),见图1。另外,再焊接一个简易多路转换开关箱,见图2。便可达到仪器车每停放一站连续接收三炮的目的。这样,仪器车就不必每一点都开进去,只需每300米停一站。
At present, the field lines used by all the field simulation teams are 30-core 50-meter pipe or two 100-meter pipe. Plug 28 feet for two rows, with the exception of 24 core for the arrangement and 2 core for communication channel, leaving 4 core 2 feet left unused. As long as the large wire welding a little change (Original Fuel Chemical Industry Ministry, 46 plants in August 1972 published “basic knowledge of seismic exploration” technology has been introduced - this printout), see Figure 1 . In addition, soldering a simple multi-channel switch box, see Figure 2. It can achieve the purpose of receiving three guns continuously for each stop of the instrument vehicle. In this way, the instrument car does not have to go into every point, just stop every 300 meters.
