beam cutoff 中文意思是什麼
beam cutoff
解釋
射束截止-
The following principles are proved : increasing cfp adhesive length will release the concentrating of shear stress near the cutoff point, this will lead to the increment of loading - bear capacity of concrete beams ; increasing the thickness of cfp will improve the transition of load from concrete beam to cfp, this is useful to exert the potential of cfp ; in creasing the anti - shear modulus of adhesive will result enhance the concentrating of shear stress, this is harmful to the effect of cfp reinforced concrete beams
本文的理論分析結果可以表明：增加碳纖維板的粘結長度可以緩解碳纖維板端部界面上的剪應力集中，改善混凝土梁結構的加固效果；增大碳纖維板的粘結厚度可以增大界面上的剪應力，改善混凝土樑上載荷向碳纖維板的傳遞效果，有利於充分發揮碳纖維布的潛能；如果粘結膠層的抗剪模量過大會加劇剪應力的集中，從而對碳纖維加固的效果不利。 -
The results also indicate that, in a piece of gain medium, the cutoff frequency, " the most quickly growing frequency " and the integral exponential gain are variables of the beam intensity, medium gain coefficient and propagation distance
在考慮了介質的增益后，截止空間頻率、最快增長頻率以及最大增長因子不再像原始b - t理論中那樣保持不變，它成了和光強、介質增益系數及傳播距離有關的一個量。
