本文提出了一个用全息滤光片代替通常所用的昂贵的窄带干涉滤光片和二色镜的简易的激光共焦扫描系统，对其应用于基因芯片的检测进行了实验研究。

The force for filtering and backwashing is from water press and pump pressure.The pressure in filtering chamber will keep same.The solution will be filtered out from inner chamber of filtering core.The solid impurity will remain on the inner surface of filtering coThe pressure difference between outer and inner chamber and.filtering resistance will be increase.

该机的过滤和反冲洗推动力均原水压头或泵杨程提供，系统滤腔的压力基本保持恒定，液体从滤芯的内腔向外流动，夹带的固体杂质被截流在过滤介质的内表面，引起内外腔压差升高，过滤阻力逐渐增大。

In filtering dampish gases or gases containing sticky dust, the tendency of dust adhering to the filter bag has long been a difficulty of the industry until the engineers tried to replace the regular filter bag with tectorial filter bag or filter bag processed water-repellent.

利用袋式除尘器处理含湿量大或粘性较大的含尘气体，粉尘易粘附布袋一直是令除尘界头痛难题。国外曾尝试试用覆膜滤袋和对滤材表面进行防水处理解决防结露和布袋糊袋的难题，取得了明显的效果。

Deferrizers and demaganizers are series of products designed by our company for underground water with comparatively high iron and managanese content according to aerating oxidation priciple.in these prducts,packed natural manganese sand in filter is applied as filtering materials,and oxygen in air is applied as oxidants,to make ferrous iron in water oxidized into ferric iron, in a same time, oxidation reaction makes its produced its produced substances left in filtering materials for purposes of deferrization and deman-ganization.

除铁锰装置是我公司针对铁、锰较高的地下水，按曝气氧化法的原理而设计的系列产品，它是利用过滤器内装填城然锰砂为滤料，利用空气中的氧化剂，使水中的二价铁，同时发生氧化反应使其物进截留在滤料中，从而达到除，除锰的目的。

The batch sand studies revealed that microbial associated with filter sand could degrade monochloroacetic acid and dichloroacetic acid within 1 day.

透过实场滤砂批次实验可知，滤砂上之微生物对於降解HAA贡献较大，且能於短时间内降解一卤及二卤乙酸。

According to ecumenic air filtration material appraised quality criterion and the characters of electret air filtration material , this paper discusses the qppraising criterion of the electret air filtration material .

According to ecumenic air filtration material appraised quality criterion and the characters of electret air filtration material the appraising criterion of the electret air filtration material is discussed .

从一般空气过滤材料的质量评价指标出发，结合驻极体空气滤材的特点，探讨了驻极体空气滤材应有的质量评价指标。

This paper describes a removal process for ethanethiol in a packed bed of the immobilized activated sludge pellets.

采用改进聚乙烯醇法制成的固定化活性污泥颗粒填充生物滴滤池，考察在不同的进气流量和进气浓度时，生物滴滤塔对乙硫醇恶臭气体的净化效率、抗冲击负荷能力以及连续运行稳定性。

The follicular epithelial cells of thyroid gland were just a few and scattered irregularly, follicular cavity was big. The numbers of TSH cell and C cell reduced, but the numbers of ACTH rose, fasciculate zone of adrenal gland broadened obviously.

模型组甲状腺滤泡上皮细胞明显稀疏，分布不规则，滤泡腔直径较大，TSH细胞、C细胞数下降，ACTH细胞数明显上升，肾上腺束状带明显增宽。

In our studies,sludges composting was used as object, fluoranthene was on behalf of PAHs,and methods included dynamic sampling,room analysis,sludges' composting,leaching of soil column,and room culture were employed. The main contents include:the concentration and the distribution of PAHs in municipal sludges in Jiangsu Province,effects of composting on the concentration of PAHs in municipal sludges,the physicochemical properties of water dissolved organic matters in sludges before and after composting,effects of sludges composting and DOM on the desorption-leaching and eco-toxicity of FLT in polluted soil,and primary investigation of mechanism on same phenomena.

本论文以污泥堆肥为原料，以荧蒽(fluoranthene，FLT)为PAH的代表，采用动态取样、室内分析、污泥堆肥、土柱淋滤和室内培养等方法，系统研究了江苏城市污泥中PAHs的含量以及分布模式；堆肥对污泥中PAHs含量的影响；污泥堆肥前后水溶性有机物的理化性质特征变化；污泥堆肥对污染土壤中FLT解吸-淋滤、以及生态毒性的影响，并对有关现象进行了机理探讨。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).
