apex angle

基本解釋

Taking cordierite and topaz for example, the specific cone-apex angle values are given, a…
并以堇青石和黃玉為例給出了具體的錐頂角數(shù)值大小，分析了錐頂角很小的原因。
Rotating the disc of the compound rest with an angle equal to half the apex angle of the cone.
將復式刀架盤旋轉一個等于圓錐體頂角一半的角度。通過搖動復式刀架操縱柄手動提供進給。
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.
而增加發(fā)射機的發(fā)散角則基本不影響接收到的信號功率。在其他參數(shù)不變的情況下，增大接收機或者發(fā)射機的仰角都減小了接收機的探測到的信號功率。
