"Hang Zhu violin concerto" improved the abilities of spacial learning and memory in mice. Its mechanism we infer is that the decrement of the activities of TchE and MAO in the cerebra resulted in the increment of neurotransmitters. But "Mozart violin concerto in D Major" have no role in the abilities of spacial learning and memory in mice.

《梁祝小提琴协奏曲》能明显提高昆明小鼠的空间记忆能力，可能与该音乐引起的脑组织的乙酰胆碱酯酶和单胺氧化酶的活性降低，减少脑组织神经递质的降解，增加其浓度，促进学习记忆能力有关；而在本研究中《莫扎特D大调小提琴协奏曲》效果不明显。

After 5 days we began to measure the abilities of learning and memory in the Morris water maze. The avoiding latency, the frequency of passing the platform and the stay time in the aim quadrant were determine in mice. The activities of TchE and MAO in the cerebra of mice were detected.

第5d后进行Morris水迷宫测试，测试期间保持音乐刺激不变，放完音乐后测试潜伏期、经过平台次数和平台象限停留时间，实验结束后处死小鼠取脑组织并匀浆，检测乙酰胆碱酯酶活性和单胺氧化酶活性。

Base on the analysis, organophosphate inducible system has been established by treatment of the swimming seedling and drenching roots with organophosphate solution. This inducible system consists of model plant Arabidopsis thaliana and methamidophos, folimat or methyl parathion which are the representative types of highly toxical OPs. Meanwhile, the responses of the esterase isozymes and the total soluble proteins to OPs in Arabidopsis thaliana have been detected by Native-PAGE and SDS-PAGE.

在此基础上，采用模式植物拟南芥和甲胺磷、氧化乐果和甲基对硫磷三种极具代表性的高毒高残留有机磷农药，通过水培和灌根的方法，建立了有机磷诱导系统，并应用变性与非变性聚丙烯酰胺凝胶电泳技术，研究了拟南芥酯酶同功酶和可溶性总蛋白对有机磷胁迫的响应。

To clarify the acetylcholinesterase changes among different developmental stages of Tribolium castaneum, the toxicological and biochemical characterizations of AChE in 10-d larvae, 20-d larvae, pupae and adults were investigated, respectively with the microplate reader method.

为了阐明赤拟谷盗体内乙酰胆碱酯酶在其各虫态间的变化关系，以期为该虫的综合治理提供一定的理论依据，本试验采用微量滴度酶标板法，分别对其10d龄和20d龄幼虫、蛹及成虫体内AChE的生化及毒理学特性进行了较为系统的研究。

Under the optimum conditions (i.e., reaction at 40℃ using hyperthermophilice esterase APE1547, 4-Cl-benzaldehyde substrate, and trichloromethane solvent), this reaction provided optically active secondary alcohol with an enantiomeric excess up to 56% and a yield up to 78%.

在最适条件（嗜热酯酶APE1547为酶源，反应温度40℃，氯仿为溶剂，4-Cl-苯甲醛为底物）下，加成反应生成的光学活性醇产率最高达78%，ee值最高可达56%。

Using different dosages of He-Ne laser irradiated the developmental eggs of Antheraea yamamai. Compared with control plot, their hatchabilities were increased and their larval duration was influenced. Individual such as abnormal and premature mutants was also obtained. The blood protein and esterase isoenzyme of their pupa were analyzed with PAGE, found some changes in band r umber and activity. All those indicated that He-Ne laser has some inductive effects on physiological and biochemical characters of Antheraeayamamai.

不同剂量的He-Ne激光辐照天蚕发育卵，当代与对照相比较，孵化率提高、幼虫龄期经过缩短，产生附属肢畸变、早熟等变异体；对蛹血蛋白质、酯酶同工酶进行PAGE分析，其谱带数和活性也产生了变化，显示He-Ne激光对天蚕的生理生化性状具有诱变效应。

An enzyme found chiefly at nerve terminals that inactivates acetylcholine by hydrolyzing it to form acetic acid and ''.

乙酰胆碱酯酶一种主要分布于神经末梢的酶，它能通过水解乙酰胆碱形成醋酸和胆碱从而使之失去活性

An enzyme found chiefly at nerve terminals that inactivates acetylcholine by hydrolyzing it to form acetic acid and choline.

乙酰胆碱酯酶一种主要分布于神经末梢的酶，它能通过水解乙酰胆碱形成醋酸和胆碱从而使之失去活性

Effects of the experiment were evaluated by studies of (1) preoperative and postoperative gastric analyses,(2) retrograde tracing of horseradish proxidase to vagi, and (3) acetylcholinesterase activity of gastric tissue.

通过手术前后的胃液分析，术后（2周～4个月）辣根过氧化物酶对胃壁神经的逆行追踪及胆碱酯酶活性（AChE-activity）的测定来评价该设计手术的效果。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
