The molecular charge distribution of the reactivator is affect the reactivating efficacy directly. Moreover its association with hydroximic acid dissociation constant pAa closely, and it will have a great impact on reactivating ability indirectly.(3) There is likely to exist front molecular interaction between Cholinesterase Reactivators and OPC-inhibited AChE, the action sites mainly lie on the aromatic ring, the substitute R and the hydroixic acid group. They act on the aromatic residues of AChE by Π-Π conjugation .(4) The reached results by Comparative Molecular Field Analysis is useful to design new higher efficacy derivatives for 1, 2, 4-oxadiazole class nonquaternary Cholinesterase Reactivators.

2复能剂分子的电荷分布直接影响复活活性，同时对肟酸解离常数pKa具有重要影响，间接影响复活能力；(3)复能剂与磷酰化酶可能存在前线轨道作用，作用部位可能主要在芳香环及其取代基R和肟基上，与AchE的芳香族残基发生л-л电子作用；(4)通过比较分子力场法研究可以指导1，2，4-oxadiazole类非季铵肟胆碱酯酶重活化剂新化合物的合成，可能得到活性更高的复能剂。

There was no observable morphological change in the macronucleus of the amicronucleate cell during the whole conjugation.

Taking advantage of a rDNA mutant,rdna-A3,which is of paromomycin resistance marker and has replication predominance over wild type r dna+,we demonstrated that among 10 000 copies of rDNA in the old macronucleus no ne could "leak" into the developing new macromucleus during conjugation.

本文以1种具有强大复制优势而且是抗药性的rDNA分子，rdna-A3，为指标，证明在接合过程中旧大核内上万个rDNA分子没有1个能进入新大核，从而在基因分子水平上证明旧大核的退化是极为彻底的。

The bulky ortho-brominated aryl groups are implanted to create nonplanarity around amino center. Thus, the effective conjugation length to the protonation site is shortened and the energy gap between neutral and protonated forms is narrowed. The protonation can only occur at the nitrogen atom of the benzothiazole and the temperature variation disturbs the equilibrium between the neutral and monocation and the reverible thermochromic effect can thus be achieved.

在邻位的位置引入立体阻碍大的溴原子，进而控制质子化过程的酸碱平衡只发生在 benzothiazole 上的氮原子上，企图达到只有中性分子，与单阳离子两种稳定的形式存在，经由外界的刺激下，例如温度或酸的量的改变，促使逆反应的发生，而达到热致变色的效果。

Ecause of stronger resonance enhancement to incident pump beam given by the Bragg microcavity, the enhancement effect of the phase conjugation wave produced by Bragg microcavity was more outstanding than that caused by naked third order NLM.

ragg微腔中的三阶NLM产生的相位共轭波相对于该介质裸露时产生的相位共轭波具有明显增强，这主要是Bragg微腔对入射泵浦光产生了较大的共轭增强作用。

In the conjugation pair, the normal cell can finish the normal meiosis process, the gametic nuclei fused, the zygotic nucleus divided and at last formed two cells with micronucleus.

对上海四膜虫有小核细胞和无小核细胞的接合过程进行了跟踪观察，发现在四膜虫中也存在胞质配合。

Even one-celled organisms count replications, and will die if they don't replenish their telomeres with conjugation.

连单细胞生物也数复制次数，如果它们不通过配对接合补充其端粒，它们会死掉。

Itwas found that the"out-group"antiparticles of Bose type, which came into being because of CP ( charge conjugation-parity conservation) violation in the early universe and became heavier due to the phase transformation from low temperature to high temperature, are the supersymmetry companionsof the"in- group"particles of Fermi type.

研究了编内粒子和"编外"粒子的对称性，发现因宇宙早期CP破坏导致从低温到高温的相变而变重的玻色型"编外"反粒子是费米型编内粒子的超对称伴子。

This paper detailed the method research of EIA for papaverine by using of the papaverine antibody and the conjugation of papaverine-HRP prepared in the former paper.
