For three different reaction paths leading to ortho, meta, para-chloropyridine, two transition states have been located by PM3 on each reaction path, while only one transition state by ab initio, however both methods give the same results: the energy of transition state and activation barrier on producing 2-chloropyridine are the lowest among three reaction paths, so 2-chloropyridine is obtained priorly, which agrees with the experimental results.

生成邻、间、对氯代吡啶三条不同反应途径PM3方法优化得到两个过渡态，而从头算方法中只优化得到一个过渡态。但两种方法的研究结果均表明：三条反应途径中生成2-氯吡啶的过渡态能量和活化能最低，因此反应优先生成2-氯吡啶，与实验结果一致。

It is suggested that the nude mouse is a suitable model for the study of psori-asis,AK auto Ab can improve the recovery of psoriasiform dermatitis.

The present research situation about AB process in and out of our country was analyzed in this paper. In addition to a concentrated study of the factors affecting sedimentation performance of A-step activated sludge, the rule of microbe multiplication, yield of activated sludge in A-step and treatment of low-concentration sewage were also involved in this paper. The main conclusions are as follows:(1) The study on factors affecting sedimentation performance of A-step activated sludge shown that the inflow SS distinctly improve sedimentation performance of activated sludge, the less influent SS makes the sludge bulking easy, and the pythogenous sewage evidently worsen sedimentation performance of activated sludge.

本文分析了国内外AB工艺的研究现状，对A段活性污泥沉降性能的影响因素；A段的微生物增殖规律、活性污泥产量以及A段工艺处理低浓度城市污水等问题进行了试验研究，得出了以下结论：（1）对A段活性污泥沉降性能影响因素的研究表明：进水中的SS对污泥沉降性能有明显的改善作用，如果进水中SS较少，易导致污泥膨胀；而腐化污水对活性污泥的沉降性能有显著的不良影响。

When cells undergo programmed cell death, cell corpses adopt a refractile and disc like structure. Using this morphological change as a cell death marker, we analyzed the death of the first 13 cells in the AB cell lineage of wild type and cnx-1; crt-1 mutant embryos.

进一步以4D摄影分析线虫AB世系细胞中最早死亡的13颗细胞之相对死亡时间和细胞尸体持续的时间长短的结果则显示，此死亡细胞数量提高的现象应是源於吞噬步骤发生问题而非细胞死亡执行上的问题。
