When capacitance influence fuze was used to full-bore rocket projectile,aerodynamic heat is still a problem to think about, so the heat resistant measure must be adopted, double-deck false cap is an effective measure to prevent from aerodynamic heat, but it is the first time to be used in capacitance influence fuze.
双层风帽是解决气动热的有效措施 ,但用于电容引信尚属首次 ,于是对双层风帽在电容引信上的应用进行了分析和讨论 ,指出了双层风帽设计时应注意的两个一般原则 ,并用试验验证了双层风帽在电容引信上的可行性。

This paper studies the natural vibration feature of orthogonal two-layer cable net in circular roof,gets the approximate solutions of two-layer cable net\'s natural vibration with Galerkin principle and L-P method,and analyzes the impact of temperature,amplitude and other factors to the natural vibration.
研究了圆形屋盖正交双层索网支承体系的非线性固有振动特性,采用Galerkin原理及L-P法求得了正交双层索网支承体系非线性固有振动的近似解。
补充资料：双层θ网环
分子式：
CAS号：
性质：一种高效实验室散装填料。用双层金属丝网制成的θ网环。其结构、特点与θ网环相同，但由于用双层丝网制成，因而增加了机械强度。
