The "NVIS"(Near-Vertical Incidence Sky wave) antenna is set on the horizon, which can clear up the dead zone of short-wave communication, and a ferrite loading spiral coil antenna is installed on the rocker projectile to receive the short wave signal.

在地面设置近垂直入射天波传播"NVIS"天线，消除短波通信静区，弹上安装铁氧体加载螺旋线圈天线接收短波信号，利用原有弹载计算机进行数据处理。

In addition, effects of weld heat input on microstructure and performance of the weldjoints are analyzed. The test results indicate that by controlling weld heat input about 16kJ/cm and practicingmulti-layer weld process, the coarse austenitic grains in the weld metal and lumpish ferrite in the heat affectedzone can be avoided so that the microstructure and performance of the weld joints can be ensured.

结果表明，采用多道焊焊接工艺，严格控制焊接线能量在16 kJ/cm左右，可以防止T91钢焊缝区奥氏体晶粒粗大，避免在热影响区出现块状铁素体组织，从而保证焊接接头区具有良好的组织性能。
