Firstly, polyacrylamide with 26 million molecular weight was compounded in lab through establishing optimum compounding initiator proportionality of 1:1. 3 and mass concentration of 170 mgL^(-1), temperature of 10 ℃, acrylamide mass percentage of 25%, electrical conductivity of 3.6 μSm^(-1) and pH value of 6.57. The salt-resistance, thermal endurance and shear-resistance of polyacrylamide could be enhanced b introducing sulfonic acid group or styrene sulfonate group or drawing the two groups above at the same time. Secondly, chelator HEDP, bactericide isoquinoline ketone and oxygen scavenger thiourea were optimized to improve the compatibility of polyacrylamide and formation water.

在由室内试验确定了复合引发剂最佳比值1：1.3和质量浓度170 mgL^(-1)、合成最佳温度10℃、丙烯酰胺单体质量分数25%、电导率3.6μSm^(-1)和pH值6.57后，合成出相对分子质量高于2.6×10^7的聚丙烯酰胺，同时通过丙烯酰胺单体复配引入磺酸基团、苯乙烯磺酸基团或同时引入此两种基团，提高了聚合物的抗盐、抗温、抗剪切性能；后针对聚丙烯酰胺与地层水配伍性差的问题，优选出HEDP螯合剂、异噻唑烷酮杀菌剂和除氧剂硫脲，对聚合物稳定效果明显。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
