最强的返回信号来自云层。
返回信号的强度提供了云和粒子的特征信息。
The strength of the returning signal provides information about the characteristics of the clouds or particles.
发射出信号并接受返回信号的天线是直接指向飞机的。
The aerial which sends out the signal and receives the reflected signal is pointed straight at the aircraft.
其他四名返回旨在促进辅助返回信号监测，不分配给群。
The other four returns are designed to facilitate monitoring of aux return signals and do not assign to subgroups.
要做到这一点，设计者必须掌握电流的实际流向和返回信号源的路径。
To do this, the designer must be certain of the actual path that the return current takes in getting back to the signal source.
不过，由于输出信号不规则，它必须进行更多的的数据处理以匹配返回信号。
But because the outgoing signal is not known it takes more processing to match it to the return.
semflg值是在返回信号量集标识符之前对访问权限进行验证时设置的。
The semflg value is set while creation is verified for the access permissions before returning semaphore set identifier.
一个接近性传感器通常会发出电磁或静电场，或电磁辐射光束(例如红外)，以及在外地或返回信号的变化看。
A proximity sensor often emits an electromagnetic or electrostatic field, or a beam of electromagnetic radiation (infrared, for instance), and looks for changes in the field or return signal.
在SHEL的最初测试中，ABL飞机使用安装在“大乌鸦”飞机上的激光信标模拟实际导弹目标会产生的返回信号。
On this initial test of the SHEL, ABL made use of beacon lasers installed on Big Crow to simulate the targeting return it would receive from a live missile target.
不过，如果程序不使用gethostbyname或者任何其他在同一对象中返回信息的函数，或者如果它每次使用时都会阻塞信号，那么就是安全的。
However, if the program does not use gethostbyname or any other function that returns information in the same object, or if it always blocks signals around each use, you're safe.
