It can beconcluded from the experimental results that in the reaction of flavonoids withα-hydroxy ethyl peroxyl radicals, 2,3-double bond in the C ring plays a moreimportant role than o-dihydroxy in the B ring.

从实验结果来看，在黄酮类化合物与有机过氧自由基反应的过程中，其分子结构中起主要作用的是C环2，3双键，而不是B环的邻二羟基。

Based on physicochemistry,work and heat in the processes of irreversible cell were discussed by thermodynamical method.

在基础物理化学的基础上，用热力学方法讨论了不可逆电池过程的功和热，给出了计算公式，并推广到无副反应的电解过程。

The enhancement of the reaction activity is attributed to the phasetransfer capability of the built-in quaternary ammonium and pyridinium salts of theMn catalyst.

分子内季铵盐和吡啶盐具有相转移能力，对于取代色烯不对称环氧化的作用与外加的吡啶盐和卤化铵的作用相似，使Mn催化剂催化取代色烯环氧化反应的活性明显提高。

The enhancement of the reaction activity is attributed to the phasetransfer capability of the built-in quaternary ammonium and pyridinium salts of theMn catalyst. The effect of the internal quaternary ammonium and/or pyridiniumsalt on the epoxidation of substituted chromenes is similar to that of the externalpyridinium salts and ammonium halides.

分子内季铵盐和吡啶盐具有相转移能力，对于取代色烯不对称环氧化的作用与外加的吡啶盐和卤化铵的作用相似，使Mn催化剂催化取代色烯环氧化反应的活性明显提高。

Copper pyruvaldehyde bis（N -methylthiosemicarbazone） complex, or Cu-PTSM, belonging to a class of neutral, lipophilic complexes ,is a positron emission tomography radiopharmaceutical that can be used to evaluate blood flow in the heart, brain, and tumors without following any side effect .

Cu-PTSM是中性亲脂性复合物，用于PET显像的放射性药物由于该制剂很容易扩散到细胞内，因此注射Cu-PTSM后可以了解心、脑和肿瘤部位的血流灌注状况，它不伴有副反应的发生，且合成比较容易，所以是一种非常有途的新型PET显像剂。

作者单位：610041 四川成都，四川大学华西医院核医学科 cu-ptsm是一种中性亲脂性复合物，用于pet显像的放射性药物。由于该制剂很容易扩散到细胞内，因此注射cu-ptsm后可以了解心、脑和肿瘤部位的血流灌注状况，它不伴有副反应的发生，且合成比较容易，所以是一种非常有前途的新型pet显像剂。

We found that, in the ventral tegmental area of anesthetized rats, the population of presumed dopamine neurons that are excited by aversive stimuli is actually not dopaminergic.

作者发现在麻醉大鼠的腹侧被盖区中被推测对令人厌恶刺激产生反应的多巴胺能神经元群体实际上不是多巴胺能的。

It is an abnormal response to a food that is triggered by the immune system and is far more serious in nature.

这是一种不正常的反应，是一种食品引发的免疫系统，更严重的性质。

There are more movements from his limbs and also frequent grinding of teeth in his mouth. There are also expressions of uncomfort, pain and saliva leaking etc. These make us feel worried and sad as parents.

手脚摆动多了，而口腔也出现频密的磨牙情况，亦有反应不舒服的痛苦样子及流口水等表现，这也叫我们作父母的担心及也避免不了因此哀伤。
