Methods The experimental TBI model was established by bumpiness of free falling body according to Feeney′s.The rats′cerebral edema were imaged with magnetic resonance image,The changes of brain water content and permeability of blood-brain barrier were measured by the methods of wet and dry weight and Evans blue fluorometry.The expression of AQP-4 mRNA was examined by reverse transcriptase polymerase chain reaction.

按照改进的Feeney自由落体撞击法建立大鼠创伤性脑损伤模型，用磁共振成像对大鼠脑水肿进行检测，干/湿比重法和伊文思蓝测定法观察大鼠TBI后不同时相脑组织含水量和BBB通透性的变化，并采用逆转录聚合酶链反应法检测AQP-4 mRNA的表达，蛋白质免疫印迹法检测AQP-4蛋白的表达。

In order to compare the homology of the gene encoding VP2 between MDPV-Q and MDPV which was registered in the GenBank, also in order to find out changes of the VP2 gene and the immuno-genicity between the wild-strain MDPV-Q and the attenuated strain MDPV-26 which derived by continued passage of virulent wild-type in muscovy duck embryo, a pair of primer (LHMP7/LHMP8) was designed. The upper one LHMP7 and the lower one LHMP8 corresponded to the MDPV-specific nucleotides sequence 2885-2900 and 4618-4604 respectively, according to the MDPV nucleotide sequence databases. The length of the sequence embraced by the primers was 1734bp.

为了获取这一基因片段与国外分离株进行同源性比较，同时也为了了解MDPV强、弱毒株VP2基因之间的异同关系，及其免疫原性的变化规律，通过DNA重组技术，设计了一对引物LHMP7／LHMP8，该对引物选取位于2885～2900及4618～4604的两段序列，跨幅为1734bp，并在这两条引物中分别加入两种限制性核酸内切酶SacⅡ和KpnⅠ的酶切位点，分别对MDPV-Q和由该株病毒经人工致弱后得到的MDPV-26株进行PCR扩增，并将PCR产物克隆到pMD18-T载体上，分别得到二个重组子：pMD18-T—M-Q VP2和pMD18-T-M-26 VP2。

As a sort of antiquated and remonstrant ideality of human being, its conception varies with libertarianism variety recently. The variety consists of the rights equality of Classical Libertarianism, Favored Libertarianism's equality based on freedom and the equal restriction of New Libertarianism.

平等作为人类一个古老和抗议性的理想，其理念在近代经历了一个随自由主义理论的变化而变化的过程，即古典自由主义的权利平等、功利自由主义以自由为基础的平等和新自由主义平等的限度。

Finally, tests of following crop row showed that shadow removal method based on illumination invariant image satisfied real-time requirement of system and improved the robustness of extracting navigation parameters under variable daylight illuminants.

最后，通过作物行跟踪试验表明，基于光照无关图的阴影去除方法不仅满足了导航实时性的要求，而且使农业机器人在光照变化的情况下导航参数提取的鲁棒性有了更大的提高。

And then obtained under some conditions of probability are some sufficient conditions for moment complete convergence for independent non-identically distributed random elements in a separable Banach space which are stochastically bounded by a positive random variable.

文章在随机元序列随机有界于某非负随机变量的条件下，引入慢变化函数l和选定的函数类S，在一定的概率性条件下，得到B值独立不同分布随机元序列矩完全收敛性的充分条件，推广了有关文献的结果。

So the present study was taken to compare the differences in the mechanisms of dissipating excess light energy in cucurbit crops and to study the differences in both the ROS metabolism in root system and the photosynthesis among six cucurbit crops with different temperature tolerance growing at different root-temperatures. The main results are as follows: 1、The species specific response of three cucurbit crops with different heat-tolerance: warm-adapted cucumber, heat-tolerant sponge gourd and heat-sensitive figleaf gourd to diurnal changes in air temperature and irradiance intensity were investigated in a typical summer sunny day. Three cucurbit species were compared using parameters in gas exchange, chlorophyll fluorenscence, photon allocation and photosynthetic electron flux.

因此，本试验以温度敏感性不同的瓜类作物为材料，研究了夏季自然条件下不同物种间在耗散过量光能的主要机制差异；探讨了它们对不同根际温度在根系活性氧代谢及地上部光合作用等方面的生理响应差异，所取得的主要结果如下： 1、在夏季晴天条件下，三种温度敏感性不同的瓜类作物：喜温的黄瓜，耐热性的丝瓜与热敏感的黑籽南瓜在气体交换、叶绿素荧光、光能分配及光合电子流对一天中温度与光照环境变化的响应上存在物种间差异和日变化特征。

The simulation results demonstrated the algorithm is stable, convergent and fair, and robust with respect to variants of stochastic delay and stochastically accessed users.

仿真证明，算法保证了闭环系统的稳定性、收敛性和公平性，对传输延迟的时变特性和用户的动态变化引起的测量误差具有较好的鲁棒性。

As part of traditional Chinese music,court music is composed of two major ingredients:"music utile" and"music dulce",the former is functionally pragmatic and therefore conservative while the latter is functionally entertaining and therefore flexible.

中国宫廷音乐文化是中国传统音乐文化的重要组成部分。就其社会功能而言，它由雅乐和燕乐两部分组成。雅乐主要体现音乐的功利性，具有相对的保守性，燕乐主要体现音乐的娱乐性，具有相对的变化性。

As the most important inhibitory neurotransmitters in the central nervous system, the concentration change of GABA plays a vital role in neuronal excitory changes and abnormal discharge.

GABA作为中枢神经系统最具代表性的抑制性神经递质，其浓度的变化在神经元兴奋性的改变、异常放电的过程中起着举足轻重的作用。

From different perspectives, we get different findings and rules, which constitute the verdicts of our research, and the following are some of them.1,Apart from the objectivity, variability, polysemy and cultural specificity, the semantic features shared by body terms and other nouns, body terms owns its unique semantic features, viz systematically metaphorical and metonymical properties.

这些发现及规律，亦即本研究的主要结论，具体如下：①人体词语的语义除了跟其它普通名词的语义一样具有客观性、历时变化性、共时多义性和文化性的特征之外，还具有隐喻系统性和转喻性两个方面的独具个性特征。
