实验测定了两种溶液的膜渗透通量随时间变化曲线；考察了气液两相流操作对两种溶液膜渗透通量的影响；对超滤葡聚糖和 BSA水溶液后的膜进行了清洗实验；对超滤前后的膜进行了扫描电镜和 XPS分析。

CTAC had the best effect, bringing the sludge cake moisture down to 68%. At 0℃, the above test was also done for the following conditions: untreated, CPAM, FeC13/CaO, and acid conditioning. The sludge cake moisture is lower at 0℃ than that at normal temperature. The untreated sludge and pH=2 sludge had the lowest moisture. At -15 ℃, CTAC brought the sludge cake moisture down to 62.8%, 6% lower than at normal temperature.

结果表明，CTAC对污泥的调理效果最好，可使污泥滤饼含水率降至68%。0℃时，未经处理、CPAM、FeCl3/CaO、加酸处理条件下污泥脱水效果较常温时都有不同程度的提高，效果最好的为未经处理和pH=2条件下的泥样；-15℃时，CTAC条件下滤饼含水率较常温下降了约6%，达到62.8%。

Factory has been gradually formed in order to filter and filter bag filter for the leading product of the professional manufacturers.

Based on this, it optimizes the model and the elevation of upstream and downstream cofferdam. It studies the design of the bedding course of the downstream concrete slab protection slop of overflow cofferdam. It puts forward relevant risk rate"s calculation models, and gives the risk rate"s calculation methods. Chapter 4 synthetically considers the key-points and difficulties of Shuibuya Hydropower diversion. It carries out diversion scheme suitable for Shuibuya high concrete facing rockfill dam.

对土石过水围堰下游砼板护坡反滤层设计进行了研究，提出反滤层设计的风险模型，并给出了风险率的计算方法；第四章在综合考虑水布垭导流与度汛工程的重点与难点及工程布置、施工要求的基础上，经多方案技术经济比较，研究确定了适合水布垭高面板堆石坝工程特征的导流与度汛方案。

The paper introduced design features and principles of the cartridge filter and its application in the shot blasting machine,analysed the reasons of its twice fires in half a year,and finally gave some relevant prevention measures.

介绍了滤筒式除尘器的原理、结构特点以及在抛丸机上的应用情况，分析了滤筒式除尘器在半年内两次起火的原因，并提出了相应的防范措施。

In order to effectively separate the fluorescence produced by algae chlorophyll-a and the scattering light from the excitation light, the interference filter with high block coefficient and narrow band is used as spectral filter.

4为了有效地分离海藻内叶绿素a所产生的荧光和激发光的散射光，采用高阻塞系数的干涉滤光片作光谱滤光。

The filters described above are still my 'must-have' landscape filters. The effects of polarizers, and colored polarizers, such as the blue-yellow filter, can not be replicated with software. Even grad filters often achieve better results in the field than post manipulation in the computer.

前文中所叙述的滤镜才是我必须拥有的风光滤镜，偏光镜和彩色偏光镜如蓝黄偏光镜的效果是不能用软件复制出来的，甚至连梯度渐变镜的效果都要比用计算机处理的要好得多。
