These would hinder the effective envenomation administration, which is also become a bottleneck for exploitation and application of this resource.

以往关于中介蝮的形态、动物区系、食性及生态、毒液的生物化学与毒理学等方面已有研究报道。

With distance from the lake,the Aerxiaote lake vegetation happened converse succession.From outside to inside,the structure of plant community was gradually simple,biological diversity was shrinking and halophytic vegetation had decreasing tendencies.From outside to inside,there were Aneurolepidium dasystachys,Phragmites australis,Suaeda salsa L.community.Succession tendency was from wetland and typical grassland vegetation to salinization and desertization vegetation.

阿尔肖特湖边的植被随着距湖面距离及地形的不同，植被发生逆向次生演替，自外向内具有植物群落结构逐渐简单，生物多样性逐渐降低、盐生植物逐渐增加有规律性变化趋势；植被由外至内依次形成了赖草、芦苇、白刺和盐地碱蓬群落梯度，其演替趋势是由湿地和典型草原植被向盐碱化和荒漠化植被过渡。

Of the approximately 4,300 known mineral species on Earth, perhaps two thirds of them are biologically mediated," says Hazen."

在地球上已知的大约4300中矿物中，有大概三分之二都是生物活动的中间产物。

Methods:We compared the scaffold structure,the result of hypodermal embeding test and cell growth curve of using collagen membrane with those of PHB.

目前临床应用的人造心脏瓣膜有机械瓣和生物瓣两种，尽管其能改善和延长患者的生命，但均未达到理想程度。

These two calibration methods were compared with numeric experiments. Results indicate that comparing with MSDM, BDM is not only available for the force calibration of non-spherical or anisotropic cells, but also for irregular cells in optical trap potential with inharmonic and asymmetric profiles. The results agree with the experiments reported.

用数字实验对这两种标定方法进行了比较，结果表明：与均方位移法相比，玻尔兹曼统计法不仅适用于各向异性非球性细胞，也适用于非简谐、非对称光势阱中任意形状的生物细胞光阱力的标定，结论与已有直接实验相符。

Accordingly, it is important to study the changes of karstic ecological system and its response to or impact on global change, based on a better understanding of biogeochemical cycling in a whole karstic ecological system.

因此，我们有必要将喀斯特生态系统纳入到更大区域或全球生态系统中进行分析研究，在充分研究认识整个喀斯特生态系统物质生物地球化学循环规律的基础上，进一步研究喀斯特生态系统的全球变化响应或影响机制，为喀斯特生态系统优化调控对策和措施提供科学基础。

Except one lungless species -''Typhlonectes eiselti'', only known from one specimen collected somewhere in South America - all Caecilians have

除了在南非发现的''Typhlonectes eiselti''没有肺之外，所有无足目的生物都有肺，但是他们同时也使用皮肤与口进行氧气的吸收。

The experiments of the biological activity for target molecula were accomplished. The experiment results of inhibiting activity against COX-2 indicated that the compound TM-II-5f had the highest inhibition rate, up to 95.59%, and yet the compound TM-II-5g exhibits weakly inhibiting activity.

对目标产物TM-II-5a~5g进行了生物活性研究，人环氧酶-2(COX-2)活性抑制实验结果表明：目标产物TM-II-5f对人环氧酶-2(COX-2)有很强的抑制活性，抑制率高达95.59%，目标产物TM-II-5g具有较弱的抑制率(0.61%)。

MSF have some advantages,such as ease to operate and mult ifunction.It is promising for practical application.

该内固定器械具有良好的生物力学性能，设计合理，能达到操作方便、多种用途效果，有较好的应用价值。

Integrated technology has two parts: 1,"liquid gold" of the infiltration, because the liquid gold of the biological potential, isoelectric point and osmotic pressure is identical with local organizations, through the neurohumoral regulation And micro-circulation mechanism, so that the rapid absorption of fluid infiltration, adequate flow, diffusion, form a network structure.

完整技术有两部分： 1、&液态金丝&的渗透，因为液态金丝的生物电位、等电点及渗透压与局部组织完全相同，通过神经体液调节及微循环机制，使渗透液迅速吸收，适当流动、扩散，形成网状结构。

Fancy gold-plated dangling earrings with facetted White Opal crystals.

花式镀金悬垂耳环与facetted白欧泊水晶。

This essay chooses the study aim from biology teachers in middle school in Shi Jiazhuang which tells us that most of the middle school biology teachers in Shi Jiazhuang have the"burnout", lower successfulness, individualize.

本文选取石家庄市初中生物教师作为研究对象，运用问卷调查的方法对石家庄市初中生物教师职业倦怠的现状进行调查，调查结果发现，石家庄市初中生物教师这一群体普遍存在职业倦怠，情感枯竭程度偏高，成就感偏低，去个性化程度最为严重。
