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。

Construction conditions of separated single lightning rob in tank farm are discussed in accordance with the analysis of the national standard.

通过对某企业油罐区独立避雷针实例的计算，计算了独立避雷针的保护半径和范围，说明独立避雷针对罐区油罐的保护作用很有限，基本不能对油罐起保护作

All the results above suggested that it was the cyclic electron transport but the xanthophyll cycle that play the key role in the photoprotection of the rice hybrids. The cyclic electron transport was enhanced under excessive light, thus more ATPs, which could be used for the repair of the damaged D1 protein, would be produced by cyclic phosphorylation.

这些实验结果首次阐明，叶黄素循环的热耗散在杂交稻的光保护中不起关键作用，而环式电子传递则对于杂交稻的光保护起至关重要的作用，其机理可能在于强光条件下环式磷酸化的加剧生成大量ATP用于光破坏的修复作用，同时避免类囊体膜的过度酸化，从而导致强光下qN的下降。

Treated with LAS, the leaf tissue of Pistia stratiotes L was damaged distinctly.

但SOD、CAT的保护能力有限，而POD是起主导作用的保护酶。

Background— We report that elevated connexin-43 (Cx-43) in stem cells preconditioned with insulin-like growth factor-1 (IGF-1) is cytoprotective and reprograms the cells for cardiomyogenic differentiation.

背景—我们曾报道通过胰岛素样生长因子-1(IGF-1)预处理干细胞使干细胞中间隙连接蛋白43 (Cx-43)水平升高对细胞起保护作用，并程序调控干细胞向心肌细胞分化。

A pillow is a rectangular cushion which you rest your head on when you are in bed.

垫子；软垫；坐垫；靠垫 2。垫 3。起保护作用的事物

AJ type safety joint is a specialized joint consisting of two parts. The specialized joint takes protective effect for drilling stem in drilling, repairing and test oil engineering, etc.

AJ型安全接头是一种由两件组装起来的专用接头，是钻井，修井，试油等工程中对钻柱起保护作用的一种专用工具。

Here we show that transplantation of embryonic cardiomyocytes in myocardial infarcts protects against the induction of ventricular tachycardia in mice.

我们的研究显示心肌梗死大鼠移植胚胎心肌细胞能够对诱发的室性心动过速起保护作用。

Cut off cut-off valve is mainly used for fluid pathway, including the cut-off valves, gate valves, plug valves, ball valves, butterfly valves, diaphragm valves, control API Cast Steel Valves valves and other folders; The main control valve for regulating fluid pressure, flow, etc., including control valve, throttle, valve and float valve, etc.; Check valve used to prevent reverse flow of fluid; Shunt valve fluid channel for distribution of destination, or two-phase separated, including slide valves, multi-valve, trap, and emptying valves and so on; Safety valve is mainly used for security, to prevent the boiler, pressure vessel or pipeline overpressure due to the damage; Multi-valve is a valve with more than one function, such as the cut-off valve can both start and end back from the role of the role of drying.

截断阀主要用于截断流体通路，包括眼镜阀截止阀、闸阀、旋塞阀、球阀、蝶阀、隔膜阀、夹管阀等；调节阀主要用于调节流体的压力、流量等，包括调节阀、节流阀、减压阀和浮球调节阀等；止回阀用于阻止流体的逆向流动；分流阀用于分配流体的通路去向，或将氧气专用阀、铜阀门两相流体分离，包括滑阀、多通阀、疏水阀和排空气阀等；安全阀主要用于安全保护，防止锅炉、压力容器或管道因超压而破坏；多用阀是具有一种以上功能的阀门，如截止止回阀既能起断流作用又能起止回作用。

The results obtained suggest that the activity of NOS and the production of NO following ischemia/reperfusion of hind limbs increased significantly, and that the endogenous NO may play a protective role during the early stage of acute lung injury after LIR.

上述结果提示，LIR后2 h时，骨骼肌和肺组织NOS活性增加，NO产生增多；内源性NO可能在LIR所诱发的早期急性肺损伤中起保护作用。

On closer examination, though, this is not a vote for multilateralism but just the opposite.

仔细审视后我们发现，这并非是对多边主义投出的赞成票，而是恰好相反。
