标准物质在产品质量监督检测中的应用

近年来，随着技术监督事业的发展，标准物质在产品质量检测中应用越来越广泛。标准物质有哪些作用？在产品质量监督检测中，如何使用标准物质来保证和控制检测质量以及需要注意的事项，笔者的体会是：标准物质的基本作用：标准物质按其定值方法、准确度、均匀性、稳定性分为一级标准物质和二级标准物质，广泛应用于各领域部门，可谓种类多、用途广。其基本作用是：第一，保存和传递物质的化学成份与特征量值、建立测量的溯源性。标准物质被国家定为依法管理的计量器具，它和国家确定的其它计量器具一样具有可溯源到国际单位制基本单位的准确…     

Stability analysis of tactical missile autopilots based on vector margin

A novel stability computation approach for tactical missile autopilots is detailed. The limi- tations of traditional stability margins are exhibited. Then the vector margin is introduced and com- pared with sensitivity function to show their essential relationship. The longitudinal three-loop auto- pilot for tactical missiles is presented and used as the baseline for all the available linear autopilots. Ten linear autopilot topologies using all the measurable feedback components are given with the iden- tical closed-loop characteristic equation and time-domain step response. However, the stability of the ten autopilots differs when considering the actuator dynamics, which limits their application. Then vector margin method is adopted to compute and evaluate the stability of all available autopi- lots. The analysis and computation results show that the vector margin method could better evaluate autopilot stability.     

Strapdown Homing Guidance System Design for Some Ammunition

The guidance is one of the main development di-rections of conventional ordnance.Strapdown homingis one of the main measures for ammunition guidancebecause of the li mitation of mass,volume,cost andlaunch overload.Such guided ammunition couldn’tdirectly use the conventional proportional guidancelawasthe strapdownseeker could only providethein-formation of line-of-sight angles in body coordinates,which could be used in attitude pursuit guidance sys-tem[1].It is well known that the attitude pur…
