The filtration performance of jy discal filters and arkal discal filters are compared.based on different filtering accuracy,micron rating(20,55,100,200 μm),and different dosages of chemicals added to the influent,the parameter differences such as turbidity,suspended solids content,fpi value,head loss,filtration cycle,flux,backwash,etc.are compared and studied.the results show that these two kinds of filters have similar performance.

采用并联式的过滤系统，对国产的亚高牌叠片式过滤器与以色列arkal公司的叠片式过滤器进行了工艺性能比较试验。针对不同过滤精度(20、55、100、200μm)的叠片，在不同的加药量下，比较研究了两种过滤器进出水的浊度和悬浮固体含量、周期产水量、fpi值、水头损失、流量、反洗等工艺性能参数差异，试验结果表明，两种过滤器的性能大体相近。

Decide on a book stack of pages that the pages should have been done in terms of control of the succedss is the weight of the paper, the heavier paper should be the manuscript pages of 8 pages, the lighter paper is usually a 16-page manuscript pages of the book, the Bible is a 32-page paper is a good idea, but the 64-page manuscript.

决定一个书叠页所应含有的书页之多寡的控制因素就是纸张的重量，较重的纸张应该是摺成8页的书页叠，较轻的纸张通常是摺成16页的书页叠，圣经纸最好是32页，但是也有摺成64页的。

This paper deals with the advance in the study of terrestrial Permian-Triassic boundary. At first, some index TPTB sections and their research backgrounds are introduced. Then, the research status on the synthesis of the TPTB, including biostratigraphy, eventostratigraphy, isotopic dating, magnetostratigraphy and sequence stratigraphy etc., is analyzed. Finally, the existing problems and the next research directions about the TPTB study are assessed.

着重介绍了几个目前陆相二叠系－三叠系界线研究的重点剖面及其生物地层学研究进展；分析了陆相二叠系－三叠系界线综合地层学研究现状，包括生物地层学、事件地层学、同位素年代学、磁性地层学和层序地层学等；剖析了陆相二叠系－三叠系界线地层学研究中存在的问题及进一步的研究方向。

Based on the PTB study situation of the studied area, two terrestrial sections and one marine-terrestrial section were chosen for the sedimentary and sequence stratigraphy study. The former are Chahe section and Zhejue section in Weining, Guizhou, and the latter is Mide section in Xuanwei, Yunnan. The definition and correlation of the TPTB were discussed based on the results of biostratigraphy, isotope stratigraphy, geochemostratigraphy, and molecule stratigraphy. Thus, it supplied a perfect base for the establishment of the TAGSSP in the area.

Greywacke samples of Middle and Late Triassic collected from Hongcan well in Zoige were analyzed by ICP-MS for REE and trace elements. The result shows that these samples were originated continental crust because they enriched in Cs,Rb,Th and high REE contents and depleted in Sr,Nb and Ta. Negative Eu anomalies and strong differentiation between heavy and light REE are significant. Both the contents and ratios of the inactive trace elements and the results based on discriminant diagrams indicated that the sedimentary tectonic setting of Zoige Basin was dominated by continental island arc and the sediment in this basin was strongly affected by continental island arc between Middle and Late Triassic.
