The change of remaining litter weight was the largest in the earlier 30 days during 60-day litter decomposition, and there was no significant difference in subsequent 30 days. The phenolic acid content of litter was significantly reduced with the decomposition time prolonging, and the releasing quantity of phenolic acid was the highest at the tenth day. The amounts of soil Aerobic azotobacter, Ammonifier and Aerobic cellulose-decomposer and the soil chemical properties such as pH, phenolic acid content, NH+4-N and available phosphorus were significantly affected by the litter aqueous extract of four decomposition stages.

凋落物分解的60d中，凋落物残留量在前30d内变化最大，30d后无显著变化；凋落物中酚酸含量随分解时间的延长，呈显著降低的趋势，且在分解10d时，酚酸释放量最大。4个分解动态的凋落物浸提液显著地改变了土壤好气性自生固氮菌、氨化细菌、好气性纤维素分解菌的数量和土壤pH值、酚酸含量、铵态氮、有效磷等化学性质。

For this study, calcium carbonate was chosen because it is relatively insoluble in water and easily dissolved in dilute acid or ammonium chloride.

在本研究中选用了碳酸钙，因为它相对不溶于水，且易溶解于稀酸或氯化铵。

Although some of the loss of ammonia can be recycled time after time in the production of solid ammonium phosphate, the problem of ammonia loss is still not solved, furthermore the relevant equipments for recycling are required, which result in more investment and operating cost.

虽然在制固体磷铵生产过程中，损失的一部分氨可以多次回收利用，但仍然存在氨损失，且增加了相应的回收设备，其投入和操作成本也有所增加。

High active enzyme was selected from several lipases which can catalysed the ammonolysis of unnatural sbstance trimethylsilylmethyl acetate.

从不同来源的脂肪酶中筛选出能催化非天然底物———乙酸三甲基硅甲酯的氨解反应且具有较高活性的脂肪酶，并首次探讨了氨源、有机介质、反应初始水活度和温度对该酶促反应的影

Then using 3,4,5-trichlorobenzotrifluoride as starting material to prepare 2,6-dichloro-4-trifluoromethylaniline through three routines, The direct ammonolysis method may realize the maximum use of the atom and it meets the modern green chemistry requirement. But the reaction must carry on under the high temperature and high pressure condition, and side reaction had occurred, the conversion was high, but the yield of the product was only 68%.

直接氨解法可以实现原子的最大利用率，符合现代绿色化学原子经济性要求，但是反应需在高温高压条件下进行，且有副反应发生，原料转化率高，但所需产品的收率只有68%。

A colorectal cancer cell line and a normal amnion cell line were transfected by this plasmid.

这些结果表明hTERT－CD／SFC系统在体内外均具有显著的抑瘤效果，且具有高度的肿瘤特异性。

Shall I believe that unsubstantial death is amorous and keeps you in dark to be his paramour?

我该相信连虚无的死神也爱慕你且带你去当他的情妇？

The study indicated that the solid dispersion have been changed into mono phase system from double phase system, and the docetaxel present in the carriers with amorphism or molecular, which insured the drug could be dissolved quickly in gastrointestinal tract.

实验表明，固体分散体从两相体系转变为单相体系，且多烯紫杉醇在载体材料中以无定形或分子形态存在，保证了多烯紫杉醇在胃肠道中的快速溶出，达到了本实验的预期目的。

These amphibolite samples have very high initial eHf values of+15.2 to +23.3 and the eHf values are tightly correlated with eNd values.

这些斜长角闪岩有异常高的εHf比值(+15.2～+23.3)，且εHf比值与已发表的εNd比值表现出良好的正相关(r~2=0.81)。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
