性选择的

Their intellectual efforts can be regarded as either a process of restraint and self-reflection in retrospect,or the deconstruction of the dominant androcentric discourse,or an expression of their traumatic experiences of being marginalized.

她们在文学世界的构建中展开着知性的思索与尝试：或在过往的回忆中对自身克制与反思，或解构男性中心话语，或因边缘身份的烙印而选择特有的抒写方式。

The proximal forearm antecubital fistula described by Gracz is a aluable option for autogenous ascular access for hemodialysis in patients with destroyed forearm eins or adanced arteriosclerotic and calcified radial arteries.

背景：由Gracz描述的临近前臂的肘前血管，对前臂静脉损坏或者进展期动脉粥样硬化和桡动脉钙化的血液透析患者而言，是有价值的选择自身性血管通路。

But injury of normal tissue is one of important factors which have to stop killing tumor cell thouoghly, in all process of tunor therapy Since the injury all over argans and cells of the body by free radical, especially significant side-effect to heart via ariblastine ,is universally accepted, we chose Adriamycin as chemical therapy medicine in our study.

由于阿霉素具有比较公认的自由基周身性损伤、特别是对心脏损伤的突出副作用，因此，本课题选择阿毒素作为化疗药物，模型制作采用在SD大鼠肝表面种植Walker－256瘤细胞株，于种瘤后第11天按2mg~(-1)kg体质量给单纯化疗组和化疗保护组的大鼠腹腔注射阿霉素，正常对照组和荷瘤对照组按相同比例腹腔注射生理盐水；同时，每日上午按0.5ml/100g体质量经胃给于化疗保护组抗氧化剂混合液，其余各组每日给于相同剂量的三蒸水；下午按0.1ml/100g体质量经胃给于化疗保护组维生素E溶液，其余各组每日给于相同剂量的处理过的油。

During preprocessing phase, build a hierarchical decomposition of the environment using an octree and create HLODs. At run time, use multiple threads to render the environment: use visibility culling to cull those invisible blocks, choose HLOD according to screen error, and also use data management and attemperation to update the data in main memory.

预处理阶段利用八叉树构造场景的分层次结构；实时渲染阶段，采用多线程进行场景的实时绘制：根据视点进行可见性剔除，根据屏幕误差选择合理的分级细节层次，利用数据管理调度进行数据的实时更新。

In the same time, water-soluble bidental phosphines ligand BISBIS sulfonated 2,2''-bis(diphenylphosphinomethyl-1,1''-biphenyl was synthesized, and water-soluble rhodium complex Cl was synthesized in situ. This complex which was used as catalysts to catalyze the hydrogenation of avermectin was also tested. Although the rhodium complex containing bidentate phosphine BISBIS showed a higher catalytic activity than one containing TPPDS, the selectivity for ivermectin was lower. How to improve the selectivity will be needed to studied in futur.

同时我们用磺化的2，2''-二-- 1，1''--联苯，以及它们的水溶性威尔金森型铑配合物和环辛二烯的阳离子铑配合物，在利用这些配合物作催化剂，考察它们在各种反应条件下对阿维菌素的选择加氢，由于反应条件以及复合催化剂体系的组成还需要进一步优化，虽然双齿膦配合物显示了较高的活性，然而选择性还有待进一步提高。

In order to achieve high whiteness bleaching, it is the key to combine various chlorine-free bleaching sequences reasonably and select suitable aid agents, activating agents and chelants for raising the efficiency of bleaching agents and improving the bleachability of pulp.

如何对各种无氯漂剂进行合理组合，以及选择合适的助剂、活化剂或螫合剂来提高漂剂的漂白效率和改善纸浆的可漂性，是实现TCF高自度漂白的关键。

Therefore the treatment of esophageal and cardial cancer is often palliative: surgical resection is reserved only to selected cases. Endoscopic palliation was the treatment of choice in a total of 265 patients 174 of which received laser therapy and 91 prosthesis intubation. The results it good in about 80% of cases.

因此食管癌和贲门癌的治疗常常是姑息性的，外科的手术切除仅局限于一些精选的病例。265例病人选择了内科治疗，其中174例用放射治疗，91例用插管治疗，结果约有80%的病例有效。

Methods①The animal model of braincontusion caused by free drop hammer was established.②The injuredtissue of rat brain were stained by TUNEL for apoptosis,immunohistochemistry for Caspase-3 and Feulgen"s for DNA. Image analysistechnique and the statistical method were employed to explorate thetemporal changes of injury time.③The DNA was extracted from ratcontusive tissue of brain and assayed by gel electrophoresis toinvestigate the relationship between the DNA fragmentation and injurytime.④One handred and seventeen cases of death from traumatic braininjury were retrospective researched to investigate the characteristicof TBI in forensic medicine.⑤The contusive tissue of human brain werestained by TUNEL, Caspase-3 immunohistochemistry and Feulgen"s methodsin the same way to analyze and disclose the linear relationship betweentemporal changes with injury time.

方法①建立大鼠自由落体打击脑损伤模型；②对不同损伤时间组的大鼠脑挫伤组织进行TUNEL、Caspase-3免疫组化、Feulgen's DNA染色，结合图像分析技术和统计学分析，探讨脑挫伤后神经细胞凋亡、DNA片段化和含量的时序性变化；③提取大鼠脑挫伤组织DNA进行琼脂糖凝胶电泳分析，观察DNA片段化随损伤时间的变化特点；④对117例颅脑损伤致死案例进行回顾性分析，探讨其法医学特点；⑤选择不同损伤时间的人脑挫伤组织同样进行TUNEL、Caspase-3免疫组化、Feulgen's DNA染色和分析，观察上述指标与损伤时间的关系。

You are asking me, I think, about the meaning of life, though you have posed y our question in code — in terms of the observable and measurable phenomenon o f senior career choice rather than the abstract, unfathomable and almost embar rassing realm of metaphysics.

我认为，你们问我生活的意义的时候，是带着指向性的——你们把它看成是高级职业选择中可见、可量度的现象，而不是一种抽象而深不可测的、形而上学的尴尬境地。

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。
