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。

And meanwhile, the result show that, stomatal restriction was the main factor of the net photosynthetic rate's decrease in the leaves of 4 Dactylis glomerata L. when stress in slight water stress and the non-stomatal restriction was the main factor of the net photosynthetic rate in the leaves of 4 Dactylis glomerata L.

盆栽控水条件下4份鸭茅光合作用机理的研究表明，随着干旱胁迫程度的加强，4份鸭茅种质的净光合速率、蒸腾速率、气孔导度及叶绿素含量均有较大幅度的降低，其中抗旱性强的ZXY04P-201下降的速度慢，幅度小，而抗旱性差的ZXY04P-239下降速度快，幅度大。

Then the higher filtration intensity, productive capacity and the phosphorus recovery are obtained for the employment of filter aid in the filtration systems of the above-mentioned 2 sets of phosphoric acid facilities with dihydrated phosphogypsum process and 1 set with the dihydrated phosphogypsum section of semi-dihydrated phosphogypsum process, except the semi-hydrated phosphogypsum section.

云南红磷化工有限责任公司有3套磷酸装置，其二水磷酸过滤系统运行状况较差，除1套半水-二水磷酸装置在半水过滤系统不能使用助滤剂外，其它二水过滤系统使用助滤剂后，装置过滤强度，生产能力，磷收率均有较大提高，助滤剂年费用仅24万元，但增加产量的经济效益上千万元。

Through the multiple comparisons, the production, single-potato weight, number of tubers per plant, per unit area of main stem number, plant height, the rate of commodity potato, or diseased plant rate, diseasedness index of the use of small whole potato seeds were better than that of the traditional cuts planting, but analysis of variance revealed that differences between the two was not significant.

多重比较表明，无论是产量、单薯重量、单株块茎数、单位面积主茎数、株高、商品薯率，还是病株率、病指，利用小整薯播种均优于传统的切块播种，但通过方差分析发现，二者之间差异不显著。

The result indicated that, although microorganism from paddy soil could directly reduce Cr, the reduecing rate and efficiency were limited; the higher Cr concentration was, the less reducing ability the microbial showed; the microbe from different paddy soils had different effects on Cr reducing abilities; The reducing ability of the microbe from Sichuan paddy soil was higher than that from Jiangxi paddy soil. Cr added could be rapidly reduced in paddy soil under anaerobic incubation, moreover, the process of dissimilatory iron reduction of soil could obviously promote the Cr reduction. The existent of Cr could delay the appearance of Fe; the higher Cr concentration was, the later Fe appeared. The delayed time of Fe appearance was in accordance with the ending time of Cr reduction.

结果表明，由水稻土中提取的微生物虽然能够直接还原Cr，但其还原速率和还原程度有限，且Cr浓度越高，微生物的还原能力越差；不同来源的上壤微生物对Cr的还原能力有所差异，其中四川水稻土中微生物对Cr的还原能力均大于江西水稻土；在厌氧培养的水稻土中，添加的Cr可以较迅速地还原，其中土壤氧化铁的微生物还原过程对Cr还原具有明显的促进作用；Cr的存在导致Fe生成的时间出现滞后，目Cr浓度越大生成Fe的滞后时间越长；Fe产生滞后的时间与Cr还原结束的时间具有一致性。

Methods: To retrospectively analyze clinical data of pemphigus patients in 84cases, all medicines were glucocorticoid, and immunodepressant medicine were used by 45 cases of the total, and 3 patients of 45cases chose autologous peripheral hematopoietic stem cell transplantation. To observe hormone dosis、therapeutic efficacy、adverse reaction and prognosis information of all patients.

回顾分析84例天疱疮患者的临床资料，治疗药物均以糖皮质激素为主，45例患者同时加用免疫抑制剂（其中3例因治疗效果差进行了自体外周血干细胞移植），观察激素用量、治疗效果、副作用以及预后情况。

Sulige Gas Field has low porosity, low permeability, low abundance, strong heterogeneity, complicate geological condition and is not very good at effective sand body continuity and connectivity, and so on. It is observed that gas well productivity of this gas reservoir is low, formation energy supply not enough, single well drainable gas is finite.

苏里格气田具有低孔、低渗、低丰度，非均质性强和有效砂体连续性、连通性差等特征；从已有的试井动态资料可以看出，该类气藏气井产能较低，地层能量供给不足，单井可采气量有限。

Tepraloxydim can be seriously affected by climate, low temperature(4 -10 ) can depress its effect, then in the range of 15 -24 and 20 -30 , the death ratio of Echinochloa crusgalliBeauv is more than 97.5%.
