The result makes clear, 2 class give urban sewage plant on the molecular quantity interval that organic owner should center the dissolvability in water water in kDa, and the content of organic matter compares hydrophoby the element of content big; of organic matter measures hydrophily interval distributings different organic thing shows water to accept filter film flux and hold back rate having distinct effect, the organic matter under molecular quantity 2kDa causes accept filter film to appear water flux attenuation bigger, organic matter is held back rate is minor, the organic matter that amounts to 57.2%; element to measure 10 ～ 100kDa causes accept filter film to appear water flux attenuation gentlier, organic matter is held back rate is older however highest the organic matter that amounts to 73.8%; to kiss scanty sex to differ shows water to accept filter film flux and hold back rate having distinct effect, classics is right of velar surface obstruction determine, confirm cause film to appear water flux and the main material that hold back rate change to be hydrophoby material, and the change that hydrophily material causes is minor.

结果表明，城市污水厂二级出水水中的溶解性有机物主要集中在kDa的分子量区间上，且疏水性有机物的含量比亲水性有机物的含量大；分子量区间分布不同的有机物对纳滤膜透水通量和截留率有着不同的影响，分子量2kDa以下的有机物引起纳滤膜透水通量衰减较大，有机物截留率较小，达57.2%；分子量10～100kDa的有机物引起纳滤膜透水通量衰减较平缓，有机物截留率却较大最高达73.8%；亲疏性不同的有机物对纳滤膜透水通量和截留率有着不同的影响，经对膜表面阻力的测定，证实引起膜透水通量和截留率变化的主要物质为疏水性物质，而亲水性物质引起的变化较小。

At present, film photocatalytic is studied mostly for treating with water pollution. Because the film will not bring the secondary pollution, and can be used again. ZnO film and TiO_2 film is mostly used as photocatalyzer, but they have some disadvantage, as they can only absorb little of the sun-light energy, the photoluminescence exciton compounds mostly, and they can be eroded easily by light. Complex semiconductor film is a good method to ravel out these problems.

目前，在光催化治理水污染方面，膜的光催化是一个研究的热点，因为膜催化不存在二次污染且便于回收和重复利用，研究较多的是ZnO薄膜和TiO_2薄膜，但是单一组分的薄膜存在光能利用率低，光激子复合率高，易发生光腐蚀等缺点，复合膜是解决该问题的有效途径，我们提出了全新的复合薄膜的制备方法—混合溶胶法。

Say film search is allied most by film stationmaster people the problem that what denounce is return rate, it is film stationmaster not only actually people what worry about, also be the problem that place of the leader of an alliance of film search couplet headaches, face numerous film stationmaster actually people, the discharge that sheet searchs alliance him general by is even with 1: Of 2 giving every collaboration the site prorata still is unable to do what one wants very much to do.

说起来电影搜索联盟最被电影站长们所诟病的就是回报率的问题，其实又不仅是电影站长们所担忧的，也是电影搜索联盟主所头疼的问题，其实面对众多的电影站长们，单凭一个搜索联盟将自己的流量均匀的以1：2的比例分配给每个合作站点还是心有余而力不足。

At constant viscosity, by increasing the liquid flow rate, the liquid film's velocity is increased; at the same experiment condition, the frequency of the liquid film is same at the same radial direction; the air current has minimum effect on liquid film bottom flow velocity, while it has an obvious effect on liquid film surface flow velocity. The longer the distance between liquid film and the inlet, the lower the pulsatory frequency and longer the wavelength.

在粘度基本不变的情况下，随着液体质量流率的增加，液膜流动速度随之增加；在同一个实验条件下，沿圆管径向各质点的频率基本保持不变；气流场速度对液膜底层流动速度影响很小，对于液膜表面流动速度有着较大的影响；沿液膜流动方向，液膜的脉动速度逐渐增加，脉动频率降低，脉动波长变长，与报道的通过快速摄像得到的液膜发展趋势一致，证实用PDA研究液膜流动是可行的。

For thin polycrystalline films, especially those with columnar structure, once the diameter of grains on the film surface is larger than the film thickness, the total area of above and under basal planes (film-substrate interface) will be larger than that of side plane. And if the film precipitates on the substrate with thermal expansion coefficient different from that of the film, great thermal stress will be introduced during annealing.

对于薄膜特别是柱状晶薄膜，当晶粒在膜平面内的尺寸大于膜厚时，柱状晶粒的上底面和下底面的面积将大于侧面的面积，如果薄膜还附着在与其热胀系数不同的基体上并在不同于沉积温度的条件下退火时，膜中将存在较大的热应力。
