查询词典 filter

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。

The basic principles and evolution process of Active Power Filter are first introduced. The scheme and structure of single-phase hybrid filter system is then illustrated and quantitative analysis is made based on the harmonic and reactive compensation principles. Through theoretical derivation, the said system has been proved to have the function of harmonic and reactive compensation.

Bacterial strains were isolated from humus mud by employing the dilution methods. Seven cellulose-degradation Strains marked as B-37, B-35,B-31, B-25, B-17, Z-a, and Z-b were selected according to the hyaloid rings on the medium of carboxymethylcellulose sodium Congo red and their efficacy of decomposing filter paper. Z-b had the strongest ability in decomposing filter paper among the seven strains and 16S rDNA analyzed indecated that it was Stenotroplaomnonas maltophilia owning to 99.8% homology. Comparing clony size of the seven strains in media with different carbohydrates and inorganic salt, we found that the potato extract and inorganic salt which contained CaCl2 0.20, MgSO4 1.25, NaCl5.00,(NH4) SO4 1.30, KH2 PO4 1.35, FeSO47H2O 0.015, Na-EDTA 0.02 were suitable for the bacteria growth.

用稀释法从腐殖泥中分离菌株，根据它们在梭甲基纤维素钠-刚果红培养基上的透明圈直径及对滤纸的崩解能力，获得7株纤维素分解细菌（编号：B-37、B-35、B-31、B-25、B-17、Z-a和Z-b），其中菌株Z-b的纤维素崩解能力最强，分子鉴定结果表明它与Stenotrophomonas maltophilia的16S rDNA序列有99.8%的同源性，初步确定为嗜麦芽窄食单胞菌。

In this paper is simulated numerically to flow of incompressible fluid entering into porous medium region from free space region in a 300mm diameter paper filter of the air filter.

To resist multipath and ISI in acoustical communication, a single filter receiving method and a new method, namely preprocessing frequency hopping filtering method, were adopted simultaneously. A controlled preprocessing frequency hopping filter was added before mixing frequencies of signal receiving system to strengthen resistance against multipath and ISI. The method was simulated respectively on two frequency hopping sequences of PN code and increasing sequence.

除了采用以往的单一滤波接收处理方法，本文还采用了一种新的接收处理方法，即前置跳频滤波接收处理方法，与其他方法不同的是在信号接收系统的混频之前增加了可控的前置跳频滤波器，可以增强抗多途和码间串扰能力，并对此方法分别采用PN码和递增序列2种跳频序列进行仿真研究。
