查询词典 essential resistance

Constant Flow Valve and the constant flow regulating valve are different: there is only one fixed flow valve valve from the valve directly feel before and after the differential pressure valve, the implementation of change in valve resistance action can be "direct action type variable resistance valve "It should not regulate the flow line, so the use of Constant Flow Valve can not be implemented to change the total flow of energy to run, and this set the flow valve as there are no imports of expensive, in the past, domestic heating systems seldom used, and only at some central air conditioning system to see.

定流量阀和恒流量调节阀不同的是：定流量阀只有一个阀瓣，由这个阀瓣直接感受阀门的前后差压，执行改变阀门阻力的动作，可成为"直动式变阻力阀"，它不能在线调节流量，因此使用定流量阀无法实施改变总流量的节能运行，而且这种定流量阀国内没有，进口的价格昂贵，以往国内的供暖系统很少采用，只有在一些中央空调系统中见到。

Constant Flow Valve and the constant flow regulating valve are different:there is only one fixed flow valve valve from the valve directly feel before and after the differential pressure valve,the implementation of change in valve resistance action can be"direct action type variable resistance valve",闸阀;It should not regulate the flow line,so the use of Constant Flow Valve can not be implemented to change the total flow of energy to run,and this set the flow valve as there are no imports of expensive,in the past,domestic heating systems seldom used,and only at some central air conditioning system to see.

订流量阀和恒流量调节阀不同的是：定流量阀只需一个阀瓣，由这个阀瓣直接感受阀门的后后佳压，执行转变阀门阻力的动做，否成为"直动式变阻力阀"，facebook外白板，它没有能在线调节流量，研建课，因己运用定淌量阀无法实施改变合流量的节能运行，而且这种定流量阀海外不，入口的价钱昂贵，以来国内的供暖体系很少采用，只需在一些中央空调系统内见到。

The traditional smoke theory considers that the smoke particles will sedimentate due to gravity after forming of smoke screen, and then the particles reach a final sedimentation velocity thanks to the effect of air-resistance and buoyancy, and the equation can be solved by the Stokes pellet resistance theory and often used to analyze the performance of smoke.

传统烟幕理论认为，在烟幕形成后，烟幕微粒受到重力的作用开始沉降，同时受到空气阻力和浮力的作用，最后使烟幕微粒达到终端沉降速度，这个速度方程可以通过Stokes圆球阻力理论求得，并被用来分析烟幕的性能。
