And all the soil samples were collected from the surroundings of cinnamon oil factory, flower fertilizer and so on. On the whole, this research mainly included two aspects:(1) To screen and ferment the strains producing the aimed enzyme and study on the enzymatic synthesis reaction of natural benzaldehyde.

其研究内容主要包括两个方面：(1)产酶菌种的筛选、发酵以及酶催化合成天然苯甲醛反应的研究通过大量实验，采用常规方法培养时，共筛出1 81株对肉桂醛有耐受性的菌株；将常规培养基换成细菌培养基以后，共筛出36株菌。

It can pick coal,wood,stone which size is bigger than the size of screen from raw coal and the rest will enter next equipment,protecting system in safety and stably condition.

它可以将原煤中大于筛孔的煤块、木块、石块等筛分出来，使符合粒度要求的物料进入下一级输煤设备，保护系统的稳定、安全。

I t can pick coal, wood, stone which size is bigger than the size of screen from raw coal and the rest will enter next equipment, protecting system in safety and stably condition.

它可以将原煤中大于筛孔的块煤、木块、石块等筛分出来，使符合粒度要求的物料进入下一级输煤设备，保护系统的稳定、安全。

Based on the introduction of the theory of the polymer solutions, the mechanisms of DNA separation by the capillary electrophoresis in non-gel sieving matrices are reviewed in this paper, which includes Ogston sieving model, various modified reptation models, transient entanglement coupling mechanisms and its improved mechanisms.

本文在介绍高分子溶液理论的基础上，综述了DNA在毛细管电泳无胶筛分介质中的分离机理，主要包括Ogston筛分模型、各种修正的爬行模型、瞬态缠结偶合机理及其改进机理等。

The this design structure and sieves ordinary is dissimilar, it has 4 side bars, the middle both sides are main, the vibrator installs above it, by it to the screening surface transmission vibration power, outside two is secondary, only plays keeps off the yard lumber the role.

该设计结构与普通筛不一样，它有4块侧板，中间两侧是主要的，振动器安装在它上面，由它向筛面传递振动力，外面两块是次要的，只起挡料板的作用。

Methods 34933 serum samples were screened by ELISA method on Treponema pallidum antibody. The samples with probable positive result were retested by toluidine red unheated serum test and Treponema pallidum particle assay. Results There were 559 serum samples with probable positive result.

对34933例标本采用酶联免疫吸附试验进行梅毒螺旋体的初筛，初筛结果为可疑阳性的样本进行梅毒螺旋体明胶凝集试验和甲苯胺红不加热血清反应素试验的检测。

Currently we are not only a producer of different types of breaking and filtering machines but also a general contractor of construction project for stone supplying,breaking and filtering systems.We also provide customers with complete service from workmanship design,equipment selection,equipment manufacturing,installation and matching equipment manufacturing.

目前不仅生产各种破碎、筛分设备的单机，而且可以大量承接砂石料场破碎筛分系统的工程设备总包，可以为用户实施从工艺设计、设备选型、设备配套及制造、安装和售后服务等成套设备生产的交钥匙工程。

Therefore produce good condition and make the materials smaller than the output granularity, especially the big-density materials and pulp get through the sieve pore together.

从而造成了较好的分离条件，使小于分离粒度的物料，特别是比重大的物粒和矿浆一起透过筛孔成为筛下产物。

Three new types vibrating screens with high screening efficiency were proposed based on the principle of screening process with constant bed thickness.

更多可行性进行了分析，大型振动筛设计中，在香蕉筛基础上，采用了由管群通过跨中的静定板与两根激振器梁的耦联构成的超静定网梁结构。

The reasons of the screen plate loosening of SRZS-3175 hot vibro screen during production were analyzed.

就SRZS -3175热振筛筛板松动的原因进行了分析，采取了相应的改进措施，并取得了良好的效果。
