critical flow rate 中文意思是什麼
critical flow rate
解釋
臨界流量-
The results of this experiment showed that pressure drop and flow velocity are related in quadratic function ; the effects of opening rate of distributor sad bed height on critical fluidization velocity are rather slight, while the effect of particle size on critical fluidization velocity is very obvious
得出結論：分佈板壓降和流速成二次函數關系；以木屑為原料，分佈板開孔率和床層高度對臨界液化速度的影響不大，粒徑分佈對臨界流化速度隨粒徑的增大而增加。 -
Critical rate of flow
臨界流率 -
The experimental results indicate that when the air flow rate is determined, the key problem for energy saving is how to keep the indoor thermal comfort at a suitable level and reduce the difference between the internal and external temperature of the room. a formula is gained for calculating the critical values of air exchange rate. when ventilating rate is greater than the value, radiating heating is the better way for energy saving, or else, convection method in heating is more suitable
實測還指出，當通風量一定時，如何保證人體熱舒適度不變而減少室內外氣溫差將成為大通風量房間節約採暖能耗的關鍵，本文結合圍護結構傳熱機理，在對三種方式的能耗狀況進行理論分析的基礎上，提出了換氣次數的節能臨界值，若換氣次數高於此值，則輻射供暖是較好的選擇，否則，散熱器供暖是較好的方法。 -
Ann is a adaptive and non - linear dynamic system made from superposition of many simple components which we call neuron. the question for computation of d _ ( cmax ) belongs to incipient motion of sediment in essence, which is the same question with two different sides, because computation of critical condition ( including critical velocity critical shear stress critical power ) for a grain size under a bed - load condition is equal to computation of a grain size during incipient motion under the bed - load condition and the water flow condition given before. and computation of gross bed - load transport rate has great relationship with standard of incipient motion
對于d _ （ cmax ）的推求，在本質上還是泥沙的起動問題，因為尋求某種床沙條件下某級泥沙的起動條件（如起動流速、起動切應力、起動功率）和尋求某種水流和床沙條件下的起動粒徑是同一問題的兩個方面而已；而對于推移質總輸沙率推求也和泥沙起動問題中的起動標準選擇緊密相關。 -
Technically, the optimum perforated degree of well is defined as its critical flow rate is equal to its flow rate
從純技術上考慮，臨界產量與油井產量相等時的射開程度即為油井的最佳射開程度。 -
The minimum requirement for supersonic separator to accomplish its basic function is that the flow inside the separator must be at the critical state at the laval nozzle throat and its flow rate must be equal to its critical flow rate, or the dehydration performance will deteriorate
改進旋流器的設計，使其摩阻盡量小，從而使激波向遠離laval噴管喉部方向移動，可以有效改善分離管的工作性能。在目前所設計的三個旋流器中，旋流器a的 -
Measuring the mass flow rate in relation to outlet pressure, the critical pressure ratio is defined as the criterion for whether the choking phenomenon takes place
此時，其流速和流量將保持一致且不受后續管路條件不同的影響，從而可起到均化噴煤量的作用。 -
The critical flow rate of well decreases with the increase of perforated degree, while the flow rate of well increase with the increase of perforated degree
由於油井的臨界產量隨射開程度的增大而減小，油井的產量隨射開程度的增大而增大，因此存在一個最佳射開程度的問題。
