During the process in studying Al toxicity to the orgaiusms, people changed the opinion that Al was innoxious in biosystems, and became more aware of the importance of the mechanisms of Al-toxicity and Al-tolerance in environmental and life sciences.

随着对Al~(3+)毒陛研究的不断增多，使人们改变了原先认为Al~(3+)无生物活性的观点，转而进一步深入研究Al~(3+)对人类、动物、植物和微生物的影响。

Recognition of morphological similarities between lamnid sharks (the most well known being the great white and the mako) and tunas has led to a general expectation that they also have converged in their functional design; however, no quantitative data exist on the mechanical performance of the locomotor system in lamnid sharks.

最近的研究工作显示了大量独特的运动适应特征，这些特征使得金枪鱼有别于其他有骨鱼，但人们对尖吻鲭鲨的运动体系却知之甚少，其原因是可以理解的：行踪不定的、危险的大型捕食动物不容易进行研究。

The experiment on electromagnetism pulse biology effect could suggest that quantities-effect of EMP effect on system morphemic and function with applying different frequency, power and expose time. Combined with epidemic investigation and medical psychological research in EMP researcher, the immediate, early stage and middle and long-term biological effect of EMP was elucidated and EMP protection standard was established.

电磁脉冲(electromagnetism pulse，EMP)生物学效应实验是通过应用不同频率、功率、暴露时间的EMP照射动物，明确EMP所致各系统形态和功能危害的量效关系，探索其效应机理；并结合对EMP从业人员的流行病学调查和医学心理学研究，揭示EMP所引起的即刻、早期、中期和远期生物学效应，提出EMP卫生防护标准，为物理防护和医学防护的研究提供重要的理论依据和实验依据。

Here, the accepted animal cell protocol was modified to adapt it to plant cells and the sensitivity to UV-B induced DNA damage was investigated in young and mature leaves of Murraya panicuata.

本研究通过对动物细胞彗星检测方法的改进，利用植物细胞原生质体作为材料，研究了不同发育期九里香叶片对UV-B诱导的DNA损伤的敏感性差异。

The best quality of MRS is that the MRS is the only noninvasive and in vivo means in detecting the changes in metabolism state and special biochemical compounds in living animal and human body, and that make it possible for us to observe the physiological and biochemical characteristic of brain neoplasma ,and the development of neoplasma.

脑肿瘤是较为常见的肿瘤，其发病率占全身肿瘤的1.8％，其中以脑胶质瘤为最多，占43.7％，脑肿瘤的诊断及治疗一直是临床及基础研究的难点及热点，为了更好的了解胶质瘤的生物学特征，寻找有效的治疗方法，人们一直在寻求建立稳定安全的脑动物模型，大鼠C6胶质瘤具有与人脑胶质瘤相似的生物学特征，且模型较为稳定，被广泛用于肿瘤生物学及实验性治疗的研究中。

Objective To investigate the anatomic aspects of intracranial part of oculomotor nerve; to establish animal model for research of regeneration and functional recovery of oculomotor nerve.

目的 研究健康SD大鼠动眼神经颅内段的显微解剖特征，建立大鼠动眼神经损伤及再生研究的动物模型，为相关实验提供造模方法。

Later, under the untypical parasternal four-chamber view which can thoroughly display the ostium of coronary sinus, the catheter was promoted further to the ostium of coronary venous sinus. Then the echocardiography technician adjusted the transducer of TTE in order to thoroughly confirm the position of the catheter tip. After confirming the position of catheter tip in the coronary venous sinus, the operator inserted the catheter into the coronary venous sinus for 3～4 mm farther. It was noted that if resistance was encountered by operator, the operation must be stopped, which was the same as x-ray fluroscopy as image guiding. TTE guiding His bundle elactric cahteter、high right atrium electric cahteter and right ventricular electric catheter in site: It is difficult using TTE singly since there are too many crossroads in inferior venous.

本研究结果显示，(1)单独应用TTE作为影像学引导进行冠状窦电极导管置放的成功率为93.8％～96.7％，并且应用TTE作为影像学引导放置专用冠状窦电极导管和普通电极导管的成功率和放置时间在统计学上无显著差异；(2)TTE作为影像学引导，除过度肥胖患者外，可完全替代X线引导进行冠状窦电极导管置放，包括鞘管和扩张管的放置、指引导丝在静脉而非动脉内的证实均可由TTE完成引导，且较X线C型臂有一定优越性；(3)TTE结合普通X线胃肠透视机作为影像学导引，可顺利完成心内电生理检查时导管的安全到位，而不需昂贵的X线C型臂，可将心内电生理检查扩大到广大的基层医院；(4)TTE较X线更易和更早期发现介入治疗的并发症如急性心包填塞等，对并发症的防治甚至挽救病人的生命至为重要；(5)动物实验研究表明，TEE可引导射频导管消融术时大头电极导管成功到位。

Searching for specific ligand to a certain recepter or enzyme in human body from secondary metabolities of plants, animals and microorganisms, Optimization of lead compound under certain theory or hypothesis, and synthesis methodology investigation of pharmaceutically active compound are all tasks of medicinal chemistry.

药物化学的研究领域十分宽广，既有从动物、植物、微生物的次生代谢产物中寻找与人体内特异性的受体、酶的激动剂或拮抗剂，又有在理论、假想指导下的先导化合物的优化，以及生理活性化合物的合成方法学研究。

Previous animal model studies have shown that benzyl isothocyanate and phenethyl isothocyanate inhibit carcinogenesis and tumorigenesis. However, the effects of BITC and PEITC on the formation of human osteosarcom are still not clear.

由过去研究发现，Benzyl isothocyanate与Phenethyl isothocyanate在动物模式下可以抑制化学致癌物引起癌化与肿瘤生成，但对於人类骨肉瘤的形成尚未有相关研究。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
