Therefore, fish's predatory control on zooplankton is higher in shallow lakes, resulting in less possibility of grazer control of algae by the Cladocera.

下行效应在浅水湖泊中可能更为重要，因此浅水湖泊中滤食性鱼类对浮游动物的捕食控制可能更强，导致枝角类几乎不可能通过牧食控制藻类的生长。

By adding an equivalent harmonic impedance in the branch circuit of power grid, this HAPF could force all the harmonic currents flow into passive power filters, which resulting in eliminating harmonic contamination more effective. And using the capacitive feature of PPF in the fundamental frequency, this HAPF could compensate fixed-capacity reactive power without increasing APF's burden. Moreover, in order to decrease APF's cost, the fundamental voltage will largely be endured by capacitor in view of the series resonance circuit tuned at the fundamental frequency, so the APF just bears little harmonic voltages.

其基本工作原理是：有源部分等效于在电网支路中串联了一个谐波阻抗，该谐波阻抗对基波电流不起作用，而对谐波电流产生很大阻碍作用，迫使谐波电流流入无源滤波器，从而达到滤除谐波的目的；同时新型注入式混合有源滤波器还充分利用了无源滤波器的无功补偿功能，在不增加有源部分容量的前提下，可以提供一定容量的无功功率；由于有源部分承受的电网基波电压不大，也没有基波电流流入，因此逆变器容量小，初期投资较小。

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.

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。

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.

Defatted wheat germ was micronized by comibmed method of hammer mill and colloid mill in order to increase the extraction rate of protein, followed by steps of alkali extraction and ultrafilter concentration, respectively. A quadratic mathematical model was developed statistically by means of Box-Behnken central composite design and response surface methodology.

The results are as follows:Defatted wheat germ was micronized useing both hammer mill and colloid mill to increase the extraction rate of protein, followed by alkali extraction and ultrafiltration, respectively. A quadratic mathematical model was statistically constructed by using of Box-Behnken central composite design and response surface methodology. Under the optimized processing parameters of 23μm particle sizes, pH 9.5 and 51℃, a maximum extraction rate, 68.6%, was achieved, which is 30.63% higher than that of non- micronized wheat germ (passing through 80 mesh sieve).

For example I often use a combination of grad filters and a polarizer, or grad filters and a warming filter to get shots that otherwise would be impossible to get without the filters (see Photo 6 ?Moberly Flats where I used a warming filter to kill the blues in the shadows and used a hard-edge grad to hold back light on the sky and peaks).

譬如，我经常组合使用梯度渐变镜和偏光镜，或者梯度渐变镜和暖调镜来获得一些在没有滤镜的情况下不可能获得的影像（参看 http：//www.photosig.com/resources/52/Photo6.jpg 图6－Moberly Flats），在此我使用一片暖调镜以消除阴影中的蓝色同时用一片硬边梯度渐变镜将天空和山峰的亮度压低。

A key point in Short Time Fourier Transform is the choice of window function. Although rectangle window is regarded as the first choice because it's featured by integral harmonic to filter signals and by DC component, decaying DC component and frequency shift of signals cause great error to rectangle window STFT. In addition, transient signals contain rich information of faults, but the fixed time window of STFT fail to collect these information.

STFT 算法关键问题之一是窗函数的选择，矩形窗以滤除信号整数次谐波和直流分量的特点自然称为首选窗，但衰减直流分量和信号的频率偏移对矩形窗 STFT 造成了很大误差；其次，暂态信号中含有丰富的故障信息，傅立叶变换固定的频窗忽略了这些特征信息。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.
