Based on the possible degradation products, Microbial degradation pathways of metsulfuron-methyl is concluded as follows: after the cleavage of the sulfonylurea bridge, 2-amino-4-methoxy-6-methyl-triazine is demethylated and the annularity reaction of sulphanilamide occurs.

甲磺隆主要降解途径首先是脲桥的断裂，然后6-甲氧基-4-甲基-2-氨基-三氮嗪进一步脱甲基，而磺酰胺类物质将进一步脱氨基环化。

Methods Rabbits were infected with cercaria of S. japonicum percutaneously. The SP immunohistochemical technique was used to analyse the expression and localization of cNOS and iNOS in the rectums of normal and schistosoma rabbits.

The changes of MDA in the plasma, CINC/IL-8 and NO in the serum, MPO in the skeletal muscle were studied at the end of ischemia and 1h, 2h, 4h, 8h, 12h during reperfusion.

分别于缺血4h末，再灌注1、2、4、8、12h，测定各组血浆中的MDA、骨骼肌组织中的MPO，血清嗜中性粒细胞化学趋化因子(CINC／IL-8)，血清一氧化氮，用流式细胞仪及免疫组化法观察各组白细胞上粘附分子CD11b／CD18和骨骼肌血管中ICAM-1的表达情况及各组的组织学改变。

Results showed that 1 soil structure in the rhizosphere was very high; water-holding capacity and organism count in the soil increased with altitude and duration of bamboo growth. However, soil etiolation and soil acidification was obvious. 2 Soil acidity was adjusted with lime; best applications were 10.625 thm^(-2) on the valley bottom, 14.811 thm^(-2) for the middle slope, and 12.558 thm^(-2) on the valley top.

结果显示：毛竹林根系活动层(60 cm)土壤结构较好，土壤水源涵养功能的大小和土壤的有机质质量分数随毛竹林成林时间和海拔高度的增加而增加；但土壤黄化、酸化特征较明显，土壤酸性调节主要以施用石灰为主，其中谷底毛竹林改造需石灰量为10.625 thm^(-2)，坡面的里白毛竹林为14.811 thm^(-2)，岗地毛竹林需石灰量为12.558 thm^(-2)；在氮磷钾3种元素中，氮素供应总体上良好，但要获得高产，氮肥的补充也是必需的。

Objective To detect the expression of CD70 in peripheral T lymphocytes of patients with systemic lupus erythematosus and the effect of azacitidine, an inhibitor of DNA methylation, on it. Methods Blood samples were obtained from 10 patients with active SLE （SLEDAI score ≥5）, 10 patients with nonactive SLE （SLEDAI score 5） and 10 normal human controls.

目的 通过研究共刺激分子CD70在SLE患者外周血T淋巴细胞的表达水平，以及DNA甲基化抑制剂氮杂胞苷对正常人外周血T淋巴细胞表达CD70分子的影响，探讨DNA甲基化在SLE患者外周血T淋巴细胞表达CD70分子中的调控作用。

The photodegradation rate of M-PPV 1 was constrained by DABCO that quenches the triplet state of M-PPV; 2increased when the solvent changed from benzene to deuterated benzene in whichthe lifetime of triplet state is longer than that in benzene; 3 was improveddramatically with high concentration of M-PPV triplet state was generated by energytrasfer from biacetyl.

发现：1能猝灭M-PPV的三重态的1，4-二氮二环[2.2.2]辛烷也能有效地抑制光氧化反应的进行；2能提高M-PPV三重态寿命的氘代溶剂也能使M-PPV光氧化降解速率加快，3丁二酮和M-PPV间的能量传递能够提高M-PPV三重态的浓度，这和丁二酮作三重态敏化剂敏化光氧化M-PPV时，M-PPV的光降解速率大大增加也是一致的。

A and B isomers could interconvert each other by an inversion of the imine nitrogen atom. In this work, we investigated the substituent effects and solvent effects. This study used the most popular one of density functional theory method unrestricted hybrid Becke three-parameter Lee-Yang-Parr (B3LYP) with the 6-31+G basis set to compute the reaction and activation energies of B/A thermal isomerization.

腙分子的异构化过程藉由转动亚胺基上的氮原子，使腙分子由A 型结构转变成B 型结构(Scheme1)，本研究运用密度泛函数理论中最常被使用的B3LYP，搭配6-31+G基底函数，计算腙分子异构化过程的活化能以及反应热，并且考虑取代基与溶剂效应对能量所造成的影响。

Different chemicals such as KH2PO4,(NH4)2CO3, KCl, CuSO4, Na2MoO4, Na2WO4, FeCl3, K2Cr2O7, acetic acid and sludge, were added to the lysimeters respectively and the settlement rate of refuse surface and generation rate of leach...

根据沉降速度与时间的函数关系，推算了填埋场稳定化时间。实验结果表明，氮、磷和钾的加入促进了垃圾降解，从而缩短了稳定化时间。其它化合物的加入对降解则影响不大

The compost of agricultural waste materials is the process that under the function of microorganism, the organic matter turn into well-rotted manure by the way of the organic matter being mineralized and humus and harmless.

农业废弃物的堆腐是在微生物作用下，通过发酵使有机物矿质化、腐殖化和无害化而变成腐熟肥料的过程，在微生物分解有机物的过程中，不但生成大量可被植物吸收利用的有效态氮、磷、钾化合物，而且又合成新的高分子有机物---腐殖质。
