We found that with the time prolongation of ogd , ttc staining of the hippocampal slices was reduced and ldh release rate was increased consistently . the percent decrease of ttc staining was significantly correlated ( r = - 0 . 933 ) to the percent increase of ldh release due to ogd insults 结果发现，随着缺氧缺糖时间的延长脑片hc染色逐渐下降， ldh释放率也逐渐增高， ttc染色下降百分率和ldh释放百分率呈显著负相关（ r 。
In chapter 3 , layer structure , purposes , operating model and market monitor of chinese power market are analyzed . the methods of atc , its merits and demerits are summarized in this paper . the ttc and atc calculation models are established 第三章研究我国电力市场的层次结构、发展的目标模式、运营模式及电力市场监管等情况；总结目前国内外atc常用计算方法及其优缺点，建立pool模式下ttc和atc计算模型，设计相应算法和程序。
Results indicated that rdi may reduce dry matter accumulation to a extent , relevant to seriousness , lasting time of rdi and crop growing stage when rdi treat was carried out . ratio of root / shoot , ttc contain in root increased , while number and total length of root per seedling decreased 试验结果表明：调亏灌溉减少根系干物质累积，根冠比、平均根长和根系活力( ttc还原量)提高；单株根系条数下降：根系活力在复水后仍保持较高水平。
Under the environment of power market , large amount of power wheeling and transmission contracts are frequently trading . it has put forward new technical problems to need be solved immediately how to calculate accurately and improve the total transfer capability ( ttc ) of transmission network 电力市场环境下，大量出现的电力转运及电网中频繁出现的输电交易使得准确计算及提高输电网的最大输电能力（ ttc ）成为亟待解决的技术问题。
This paper includes four chapters . atc , which is anxious to be solved , is studied from three aspects , which are optimal power flow calculation in power systems , calculation of ttc and atc in power pool model and atc calculation in bilateral exchange model 本论文共分四章，分别从区域电力市场最优潮流计算、电力库( pool )模式下最大传输容量( ttc )和atc计算、双边交易模式下atc计算等三个方面，研究和解决了当前电力市场运营中急待解决的atc课题。
Sequence analysis showed that , this fragment has a homology of 99 % to the previously reported choe from rhodococcus equi . after cloning and subcloning and three identical fragments were obtained from three independent pcr , lacking three continual bases ( ttc , encoding the pheamino acid ) compared with choe , thus it can be assumed that the new fragment , designated as choew , and choe belong to the same gene family , even it might be the natural mutation of choe 对片段进行克隆、亚克隆之后测序分析，发现与已克隆的来源于马红球菌的胆固醇氧化酶基因cboe有99的同源性；并且三次独立的pcr均得到相同的片段，所克隆的基因序列与choe相比，连续缺失三个碱基( ttc ) ，即相应的氨基酸序列缺失一个氨基酸( phe ) ，因此判断所克隆的基因片段与choe属同一基因家族或原有基因的天然突变体，命名为choew 。
In vitro injury models of brain slice ( ogd and nmda insult ) and primary neuronal cultures ( nmda insult ) oxygen / glucose deprivation ( ogd ) - induced injury of rat hippocampal slice in vitro the rat hippocampal slices prepared were allowed to recover in the normal artificial cerebrospinal fluid ( acsf ) bubbled with gas mixture of 95 % o2 + 5 % co2 for 1 h , then they were thansfered to glucose - free nacsf which was bubbled with gas mixture of 95 % n2 + 5 % co2 . after treatment with ogd , the slices were placed into 2 % ttc solution in dark and incubated at 37 * cfor 1h . the slices were weighted and a 50 : 50 mixture of ethanol / dimethyl sulfoxide was then added to extract the formazan in dark for 24 h 离体脑片损伤模型（ ogd和nmda ）及原代培养神经元nmda损伤大鼠离体海马脑片缺氧缺糖（ ogd ）损伤大鼠离体海马脑片制备后，在通氧混合气的正常脑脊液（ nacsf ）中恢复60min ，然后移入通氮混合气的无糖脑脊液（吵化sf ）中缺氧缺糖，取出脑片与2 ttc避光37 ’ c温浴60dll ，染色后根据每克湿重加入20ml抽提液（乙醇：二甲亚矾一50 ： 50 ） ，在密闭容器内避光置24h ，测量前摇匀后取200pi至96孔板，在490urn波长，酶标仪测定各孔od值。
At 22 h reperfusion , removal of androgens by castration provided protection from ischemic injury in both cortex and striatum ( 2 , 3 , 5 - triphenyltetrazolium chloride ( ttc ) histology ) , whereas dht replacement ( 50 mg subcutaneous implant ) restored infarction volume to that of the intact male ; testosterone ( 50 mg ) had similar but less potent effects 再灌注22小时时，通过阉割来去除雄激素对皮层和新纹状体的缺血性损伤都产生了保护作用（氯化三苯四唑组织学） ，相反的，双氢睾酮替代（ 50毫克皮下植入）对于完好的雄性动物也恢复了梗死面积；睾酮（ 50毫克）有着相似但更弱的效应。
Xinyuan ttc of sichuan university science and technology park international exchange department with country related educational institution and such as the france , canada , us , england , australia , japan , south korea has established long - term , the stable international exchange and the cooperation relations , successfully has implemented , has completed and country many international educations exchange project n and so on france , canada , germany , japan , singapore , accumulated the precious experience , has won the service object and society ' s trust and the high praise 四川大学科技园新源人才培训中心国际交流部已与法国、加拿大、美国、英国、澳大利亚、日本、韩国等国家有关教育机构建立了长期、稳定的国际交流与合作关系，已成功地实施、完成了与法国、加拿大、德国、日本、新加坡等国多项国际教育交流项目，积累了宝贵的经验，赢得了服务对象和社会的信任和好评。
The calculation of ttc involves network limitations due to thermal and voltage stability limits . network limitations are to be calculation not only for the current operating but also for a worse case that could occur due to a set of contingency cases , which require huge amount of computation 本文以连续潮流技术为基础，提出了考虑各种约束条件的电力系统区域间最大输电能力的分析与计算，考虑了电力系统运行中鞍型分叉点造成的静态电压稳定性约束条件等的计算。
