The highest H〓S loading of the process is 6500gS/(m〓 padding d), which is far more high than that of similar process that runs under the neutrophilic condition, and is about 2 to 3 times of that of trickling filter bed under acidophilic condition.

包埋固定化微生物滴滤床处理硫化氢的最大负荷为6500g/m〓填料·d，远高于中性运行的同类装置的负荷，也比同样为酸性环境下运行的生物膜滴滤床负荷高2～3倍。

Instruction: air cell is used to rectify excursion of filter cloth and assure normal running of filter cloth.

说明：气囊是用来纠正滤布的偏移，保证滤布的正常运转。

We also get a representation theorem for Bi-difference sets.2. Ideal and filter are two important concepts in quantum logic. From the order structure and algebraic structures of effect algebra, there are many definitions of ideals and filters.

理想和滤子是量子逻辑中的两个重要概念，由于量子逻辑有自身的代数结构和序结构，因此有多种意义下的理想和滤子概念。

3Based the trait of the vegetable gum drilling and completion fluid, used LV-CMC,FJ-03, polyglycol, JL-α and SMP-Ⅰas the filtration control agents which should be optimized. Finally this paper optimized LV-CMC and polyglycol as the filtration control agents. In order to form a tough impermeable cake, this paper used QS-2 as the inflexible filling material according to the mechanism of fluid loss control.

根据植物胶钻井液完井液的特点，确定LV-CMC、FJ-03、聚乙二醇、JL-α、SMP-Ⅰ为降滤失剂的优选对象，通过实验优选出LV-CMC、聚乙二醇为植物胶钻井液完井液体系的降滤失剂，并根据钻井液的降滤失机理，为使形成更加坚韧致密的泥饼，确定QS-2作为刚性填充粒子。

Abstra :This paper indicates the design of attaching the remote monitor and control system on the one of tobacco machine complex—filter rod making machine, and give the brief introduction of the basic knowledge of filter rod making machine, this paper also lays emphasis on how to realize the design of the remote monitor and control function on the filter rod making machine.

摘 要：本文简述了针对烟草机械的机组之一——滤棒成型机组如何在现有基础上附加远程监控系统的设计方案，并且简单介绍了有关纤维滤棒成型机组方面的基本知识，重点说明了如何实现对于纤维滤棒成型机组远程监控功能的实现和设计选择。

Therefore a GD sand-screening pipe is developed, which is helpful to the environment protection. This new sand-screening pipe consists of center pipe, sand filter and guide shoe. The center pipe is machined from 64mm tubing, and the sand filter is made from silica sand, cement, additive.

这种环保型滤砂管由中心管、滤砂器及引鞋组成，中心管采用 6 4mm油管加工而成，两端为特种 6 4mm平式油管螺纹，管体上每米均匀分布 72个直径 10mm孔眼；滤砂器是根据不同技术标准筛选不同粒度的石英砂、油井水泥、添加剂和水按配比加工压制的。

Since there is a close connection between principal filters and the smallest complete semi-lattice congruences on a po-semigroups, the study of the structure of filters has attracted a number of authors. For example, Kehayopulu, Xie X.Y, Cao Y.

在偏序半群中，由于主滤子同最小完全半格同余乃至完全半格同余有着密切的联系，又主滤子在偏序半群结构的研究中起到至关重要的作用，因而对滤子结构的研究吸引了众多学者的关注。

The method includes the steps of: suspending the filtration operation; performing a cleaning process on the membrane wall to dislodge contaminant matter from the membrane wall into liquid surrounding the mem brane: performing a sweep of the feed-containing vessel (6) substantially parallel to the longitudinally extending membranes (7) to remove the liquid containing the disloged contaminant matter, at least in part, through the openings (10) in the header (8, 9) or, where only the upper header (8) is used, through an opening (12) in the module, and then recommencing the filtration operation.

该方法包括以下步骤：暂停过滤操作；对滤膜壁进行清洗操作，将滤膜壁上的脏物冲到该滤膜周围的液体中；冲洗大体平行于纵向延伸膜(7)的进液容器(6)，使包含冲洗下来的脏物的液体至少部分经端板(8、9)上的开孔(10)排出，或者在只使用上端板(8)时，经过滤组件中的开口12排出；然后重新开始过滤操作。

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

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
