查询词典 Pi

The pI of these components gradually decreased f rom pH 4.0 according to electrophoresis mobility from higher to lower on PAGE. The molecular weights were in the range of 22～34 ku. 6.5 and 7 w ere glycoproteins proved by staining with the shiff reagent and thymol/sulfuric acid. The fibrinolytic activity of 7 was highest as determined usi ng chromzym UK and chromzym PL as specific substrates.

这些组分的等电点按照它们在聚丙烯酰胺凝胶电泳图谱上的顺序从4.0开始依次降低；SDS-PAGE证明，除3、4外，其余组分均只含一种多肽链，分子质量在22～34ku之间；用shiff试剂和酚-硫酸染色，显示1、2、6.5和7是糖蛋白，其中7的糖含量最高；以BAEE、Chromozym UK和Chromozym PL为底物测定，7的纤溶酶活性最高。

The chief reason for this choice was that the PI was mathematically tractable.

这样选择的主要原因是这种性能指标在数学上便于处理。

This winter severely cold causes the port city partial seafood cultivation to lose in a big way, some fishing boats are also frozen in the wharf, approached the shore several pools to tie an about two centimeters thick ice, was apart from the shore far pool also to float some ice pieces, he said approach shored in these pools raised is the trepang, their Pi Caorou was thick, the day cold has drilled to under the pond bottom stone, will therefore not be frozen to death, so long as the oxygen deficit line, did not compare the trepang, how the abalone not anti-has frozen, because Bao fish flesh direct dew in outside, so long as in pool oneIces up, will have many abalones to freeze to death, transported south early the abalone is good.

烟台分类妈妈消息，今天一尾号是6215的网民来电说想告诉大家一条关于的相关信息：今冬严寒造成港城部分海鲜养殖损失较大，一些渔船也被冻在码头，靠近岸边的十几个池子都结了大约两厘米厚的一层冰，距岸较远的池子里也漂浮着一些冰块，他说靠岸的这些池子里养的都是海参，他们皮糙肉厚，天冷了就钻到池底的石块下面了，因此不会被冻死，只要不缺氧就行，相比海参来说，鲍鱼就不怎么抗冻了，因为鲍鱼肉直接露在外面，只要池子里一结冰，就会有很多鲍鱼被冻死，早早把鲍鱼运南方就好了。
