迭加的的英文
superposed
例句与用法
- The wind loading of a tracking radar antenna , for example , results from a mean velocity component that varies with time plus superimposed random gusts
例如跟踪雷达天线的风力负载是由一个随时间变化的平均速度成分与迭加的随机阵风组成的。 - At input end , symmetric - to - asymmetric transformation ( sat ) is implemented before transmitting and transform symmetric signal into asymmetric signal . but additive symmetrical distributed noise is vanishes through odd - order cumulant
在输入端先采用对称?反对称变换，将对称信号变换为非对称信号，但对于信道上迭加的对称性噪声，通过奇数阶累积量运算后会抵消。 - The reason that the noise is lower with inclining tongue is : 1 ) both the radius of the tongue and the gap between the tongue and the blade are changed across the wideth ; 2 ) the phase angle between blade and the tongue is changed across the wideth , therefore the peak value of the noise do not appear at the same time , so the peak value of the noise with inclining tongue is much lower than the straight one . the influence of the expanded angle of the shell of the fan on the noise was invested experimentally , and the optimal angle was got
倾斜蜗舌降噪的主要原因是：一是改变了从气流入口侧到风机轮盘的蜗舌间隙和蜗舌半径；二是改变了叶轮与蜗舌非定常相互作用的相位差，使其产生噪声也有相位差，迭加的结果进一步降低了噪声。另外，试验研究了不同蜗壳扩张角对风机噪声及效率的影响规律，蜗壳扩张角选择当否，对效率和噪声影响较大。 - Abstract : the maximum tube distribution numbers in tube sheet limited circle for fixed tube sheet heatexchanger have been determinded by used of the superposition method with computer based on c language programming . it is characterized by determination the maximum tube distribution number according to the even number or singular number of center tube distribution . the method is simply and quickly , and can be used for the design and process calculation of heatexchangers
文摘:采用迭加的方法，使用c语言编程在微机上实现管板布管限定圆最大布管数的确定.该方法可根据中心布管数是奇排列还是偶排列来确定最大布管数，简便易行，计算速度快，对换热器的设计及工艺计算具有实用价值
