锁定

It locks the frequency of the carrier-wave at 35MHz.The stabilization of the carrier-wave can be 4×10-5,the accuracy can be 3×10-5.The frequency modulation and the confection of the carrier-wave are realized by the capacity-changing diode V149 and the integration voltage-control oscillator MC1648 chip.The end power amplifier uses the audion 2SC1970 to make it work in the third magnifying state,it improves the efficiency of the magnifier and the power of the output reaches the design demand.

发射部分采用锁相环式频率合成器技术， MC145152和MC12022芯片组成锁相环，将载波频率精确锁定在35MHz，输出载波的稳定度达到4×10-5，准确度达到3×10-5，由变容二极管V149和集成压控振荡器芯片MC1648实现对载波的调频调制；末级功放选用三极管2SC1970，使其工作在丙类放大状态，提高了放大器的效率，输出功率达到设计要求。

Locked on to the GMU's frequency now, Miriya and Bela began to relax some; but as they approached the ten-wheeled battlewagon and its support cluster, they saw something that delivered them to the edge of panic: both the vehicle's launch doors were wide open, and local space was littered with VTs and Logans, even half-a-dozen reconfigured Hovertanks.

米莉娅和贝拉现在已经锁定了GMU的通讯频率，她俩刚刚松了口气；但当她们接近这驾十轮战车以及车下的支撑圆球群时，眼前的景象将她们推向惊恐的边缘：战车的发射门全都洞开，周围空间散布着变形机和摇石机，还有五六个改装后的气垫坦克。
