It is taken the first which helicopter tail rotor dynamic sign is analysed,the reson for failure was analysed from affecting dynamic characteristic side,the reson for failure has been confirmed when it combined with fault tail rotor checking in further.

Through adopting a new special control loop that composed of hydraulic components,can find a simple and reliable way to achieve the latch-control between explosion-proof hydraulic hoist and hosting signal system.

This paper outlined working characteristics,composition,application and improvement of CGW intelligent CH 4 sensor,which not only measures and shows CH 4 instantaneous density,out-bounder warning,but also outputs frequencies being direct ratio to the content of the measured CH 4 or constant electric current sign.
