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。

We recommend that basal cell adenocarcinoma be included in the differential diagnosis of lacrimal gland tumors..

我们建议基底细胞腺癌应该包括在泪腺肿瘤的特异性诊断中。

Conclusion］ Acupuncturing Baihui acupoint has marked improvement to the blood supply of vertebrobasilar of ischemia necktype dizziness.

结论］针刺百会穴对颈性眩晕椎－基底动脉供血的改善有较明显的效果。

The most stable structure was that in which the adsorbs with its two P—O bonds faced to the substrate surface.

最稳定的结构是H2PO2-中的两个P－O键朝向基底表面。

In cells that were positive for K3, weakly positive p63 staining was observed. After airlifting, involucrin showed positive staining in cells on the upper part of the cell sheet while staining for connexin 43 was observed in the basal layer.

暴露于气液面后，培养的角膜缘上皮细胞形成3-5层结构，外皮蛋白在外层细胞表达阳性，连接蛋白43在基底层的细胞中表达，而K3阳性的细胞很稀疏。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
