In China, the high rise structures load code is used for the large span spatial structures, only the first frequency is taken account for the wind vibration analysis, which is not reasonable.
我国现在仍是采用高耸或高层结构的荷载规范，只取结构的第一阶频率计算风振系数，按此方法进行大跨空间网格结构的风振分析是很不合理的。
One way to improve beam quality is that the frequency having high nonlinear gain should be filtered by spatial filter pinhole.
改善的方法之一就是利用空间滤波器小孔将非线性增长很快的部分滤掉。
Numerical simulation shows that the spatial resolution is enhanced by four times using the frequency-domain deconvolution algorithm with high temperature accuracy.
理论仿真结果表明，采用频域反卷积算法可以在不降低光源脉冲宽度的情况下，将空间分辨率提高四倍。
High spatial frequency terms of the turbulent spectrum are sampled and low spatial frequency terms are revised using this treatment.
该算法既可对湍流的高频谱抽样，亦可对湍流的低频谱进行修正。
It follows, that where the igneous basement is concealed by a sediment cover, the gravity anomaly may contain a high spatial frequency signal corresponding to the morphology of the buried basement.
意思就是说重力异常中频率比较高的信号可能与沉积层覆盖下的基底的起伏有关。
