查询词典 mean difference

What's the difference between Beijing time and Greenwich Mean Time?

According to the difference of Doppler spectra of meteor trail echo and clutter of ground and sea, a FIR high-pass filter is designed to filter out clutter and so the meteor trail echo becomes obvious. Then a smart threshold is obtained from the minimum mean of different segments of background noise and used to detect the meteor trail echo. Finally the phase discontinuity of clutter from the meteor trail echo suppression is eliminated by substituting the data at echo positions with clatter.

该文根据地海杂波与流星干扰在多普勒谱上的差别，提出了用FIR型高通滤波器滤除杂波使流星干扰凸显出来；再根据流星干扰的分布特点分段计算背景噪声均值，求取流星干扰检测门限；最后用杂波信号来插值流星干扰位置上的数据，消除因去除干扰造成的杂波相位不连续。

为此， 运用有限元法对稳态温度场作了计算，求得管板、筒体等部件的平均温度、内外壁温差，并将这些参数作为应力场分析的热载荷；将废热锅炉离散为由板壳元和杆单元组成的空间结构，对自重、压力、温度组合的4 种工况进行计算，得到管板、筒体等部件的应力场分布规律。

The polymorphism information content were 0.6674, 0.6035, and 0.5615, respectively. The total mean of litter size of genotype LSCV043 107 bp/123 bp was significantly higher than that of genotype 110 bp/123 bp. The liner size of the first lambing for genotypes BMS2508 154 bp/154 bp, 154 bp/170 bp and 154 bp/200 bp were significantly higher than that of genotype 170 bp/170 bp (P.05). Furthermore, total litter size for BMS2508 170 bp/170 bp was the lowest in all the genotypes within this locus (P.05). No significant difference was detected in other genotypes.
