apex angle

基本解释

Taking cordierite and topaz for example, the specific cone-apex angle values are given, a…
并以堇青石和黄玉为例给出了具体的锥顶角数值大小，分析了锥顶角很小的原因。
Rotating the disc of the compound rest with an angle equal to half the apex angle of the cone.
将复式刀架盘旋转一个等于圆锥体顶角一半的角度。通过摇动复式刀架操纵柄手动提供进给。
It is also indicated that decreasing either the apex angle of transmitter or receiver makes the detecting of the weak scattering more difficult while other parameters remain the same.
而增加发射机的发散角则基本不影响接收到的信号功率。在其他参数不变的情况下，增大接收机或者发射机的仰角都减小了接收机的探测到的信号功率。
