The contents of chlorophyll and soluble protein decreased continuously in both CMS and their maintainer; while the contents of soluble sugar, praline and the activities of three protective enzymes at first increased, then decreased under cold-stress.

随着低温处理时间的延长，不育系和保持系叶绿素和可溶性蛋白质含量一直下降，可溶性糖和脯氨酸含量呈现先上升后下降的趋势；SOD、POD和CAT活性呈现先上升后下降的趋势。

At the same time, the leaf contents of soluble sugars, proline and MDA significantly increased with the decline of the temperature.

同时，随着处理温度的降低，可溶性糖、脯氨酸和丙二醛等的含量均明显增加。

After subjected to the streaming treatment, the dispersion of the loaded Mo species pronouncedly increased, and some Mo species with small particle size migrated into the zeolite channels and reacted with the Brnsted acid sites to form (Mo2O5)(superscript 2+) dimers.

经高温蒸气处理后，催化剂上Mo物种的分散度显著提高，有较多的Mo物种迁移至分子筛的孔道内，并与B酸发生强相互作用生成钼氧二聚体，有效地增强了催化剂的抗积炭能力。

Forβ-l,3-glucanase,its activity increased to peak level after 2 to 5 days and was 2.02 and 1.34 folds of check,then decreased rapidly and resumed to normal level after 5 and 9 days.Generally Psoralea corylifolia L.extract may enhance the activities of chitinase andβ-l,3-glucanase in cucumber leaves,then induce the enhancement of activities of defensive enzymes.

从所测定的几种酶活性变化时间来看，补骨脂提取物处理黄瓜幼苗后，首先，使黄瓜体内的几丁质酶和β-1，3-葡聚糖酶等病程相关蛋白活性升高，然后在两者的作用下，诱导了黄瓜体内过氧化物酶、多酚氧化酶、苯丙氨酸解氨酶等一些防御酶活性的提高。

By using a mixture of aromatic hydrocarbon and water as a binary solvent,reaction of pyrogallol with PhCCl 3 was carried out in the presence of a catalyst(ZnCl 2?AlCl 3 or SOCl 2).2,3,4-Trihydroxybenzophenone was obtained in yields of 80%-87% with the advantages of easy control,stable yield,high product quality and low cost.

以焦性没食子酸为起始原料，在惰性气体保护和催化剂(ZnCl2、AlCl3或SOCl2)的存在下，在芳香烃与水组成的二元混合溶剂中，与三氯甲苯反应，经过芳香烃溶剂的后处理，可以得到2，3，4-三羟基二苯酮，产率最高达87%。

The optimal process of chemical conversion treatment for AZ91D magnesium alloy in the alkaline bath containing pyrophosphate and stannate was determined by the orthogonal experiments.

通过正交试验确定了以焦磷酸盐和锡酸盐为主要成分的镁合金化学转化处理的最佳工艺。

The best conditions were: ethanol/acetone as solvent, molecular ratio of racemate to resolving agent 1.0:1.0, using heating as method of reaction, concentration of racemate 20mg/ml, crystallization temperature 1℃, crystallization time 8 days.

最佳结果为：乙醇／丙酮一 5.85，则为溶剂；L＜一卜苹果酸与佐匹克隆摩尔投料比为10二0；佐匹克隆20mg／ml；反应物溶解方式为加热处理；结晶温度l℃；结晶时间sd进行拆分。

The damage possibility due to the redeposition layer was ruled out by acid-etching the grating's front surface.

为了判断光栅前表面的损伤原因，在第二轮实验中对光栅前表面进行酸蚀处理以消除抛光再沉积层的影响。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
