查询词典 critical pressure

The Automatic Control Valves ABS is ABS for short, which is based on the conventional brake system security technologies to enhance improved by controlling the brake hydraulic flaps to achieve control of the wheel locking, the braking process , only when the wheels tend to be controlled when locking, ABS will tend to locking of the wheels anti-lock brake pressure regulation; in the control wheel was not tended to locking, the braking Butterfly Valves process and the conventional system exactly the same dynamic system, the braking process, its work process is actually locking - release - Locking - release cycle of the working process, the vehicle is always in the critical state of locking of the roll gap.

而ABS是制动防抱死系统的简称，它是在常规制动装置基础上的加强改进的安全技术，通过控制刹车油压的收放，来达到对车轮抱死的控制，在制动过程中，只有当被控制车轮趋于抱死时，ABS才会对趋于抱死车轮的制动压力进行防抱死调节；在被控制车轮还没有趋于抱死时，制动过程与常规制动系统的制动过程完全相同，其工作过程实际上是抱死—松开—抱死—松开的循环工作过程，使车辆始终处于临界抱死的间隙滚动状态。

Using Field single ignition experiments of the four unconfined volume dispersion and small dosage solid FAE and TNT bombs experiments, we got the peak overpressures of solid FAE at different distances. Compared with TNT, The overpressure of FAE is 1.14~1.6 times higher than that of the TNT. Based on the theory of the air shock wave overpressure, the FAE relativity TNT mass is evaluated. At the edge of the explosive field, the number is 3.88. Pictures of high speed photography indicate that the duration and the most effect area of the FAE and TNT. Compared with TNT, obviously the FAE has more advantages. And, based on the theory of the critical concentration of dust explosion, the radius of dust explosive zone is evaluated. The phenomenon that the overpressure decays rapidly with distance is analyzed. It is suggested that the explosive temperature should be increased as the main approach to improve the FAE explosive capability in the condition when the over pressure is invariable.
