查询词典 approximates

The finite difference time-domain method is stable and easy to be used, but due to the fact that it approximates the space derivatives in Maxwells curlequations by central difference, FDTD usually requires more than 20 grids perwavelength to achieve acceptable accuracy. As a contrast, pseudospectraltime-domain method approximates the space derivatives by pseudospectralmethod, which guarantees the accuracy, theoretically requiting only 2 grids perwavelength.

传统的电磁场数值算法——时域有限差分法稳定而易于实现，但由于FDTD采用中心差分近似Maxwell旋度方程的微分，每个波长上需要取的网格数通常较多，而时域伪谱法采用伪谱法求微分，理论上每个波长只需要取两个网格便可以达到较高的精度。

There are 13.944335 synodic months in a full moon cycle, the 251-month cycle approximates the full moon cycle to 13.944444 synodic months and the 767-month cycle approximates the full moon cycle to 13.9454545 synodic months .

一个满月周期相当于13.944335交点月，251个月（18个周期）的周期接近13.944444交点月，而767个（55个周期）月的周期使满月周期对应为13.9454545焦点月。

By use of bipartition, the entropy of each wavelet block approximates to the target bit rate of one. 5. An efficient algorithm is presented for constructing quantization tables of wavelet blocks with optimal bit allocations for a given image. The algorithm uses wavelet coefficient distribution statistics in a novel way, and pays attention to the traits of HVS.

该算法首先根据每个小波块所含能量的多少和到每个小波块实际编码所用的比特数，给其分配不同的码率；然后根据二分法，通过调整各小波块的量化因子使得各小波块的熵逼近它的目标比特率。
