The most appropriate catalyzed temprature and pH for it is 60 ℃ and 5.5 respectively. It has the extreme stability at the temperatures no more than 50 ℃.The CMC-Na has the protective effect on the cellulase. The pH stability range of the purified cellulase is 4 ~ 8. Zn2+, Ca2+, Mg2+, K+, Li+ can ativate the cellulase. And cellulase can mainly decompose CMC and salicin, but can decompose other substrates feebly.

对这个组分的催化性质进行了研究，该酶的最适催化温度60 ℃，pH值为5.5，在50 ℃以下酶的稳定性较好，70 ℃条件下底物对酶有较强的保护作用，该酶的pH稳定性范围为4～8， Zn2+，Ca2+，Mg2+，K+，Li+对酶活有促进作用，Mn2+、Co2+、、Fe2+、Fe3+对酶活起抑制作用，酶对CMC-Na和水杨素有分解作用，而不分解脱脂棉和滤纸。

Therefore, the indicatrixes of the liquid segregation mainly with immiscibility are the saltatory variation type of REE model evolution and the sep arative feature of main-evolution trend line either with sub-evolution trend line or with composition point of Li-F granites in the diagrams of REE-n and La/Sm-La.

因此，不混溶为主的液态分离标志是稀土模式演化突变类型和Li-F花岗岩在REE -n、La/Sm-La图解中主演化方向线与次演化方向线或与成分点呈分离特点。

The effect of predeformation degree on tension property of 8090 Al-Li alloy before aging is studied by using transmission and scanning electron microscopes and tensile machine.

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.
