变化点

This investment of energy before the deadline pays off immensely when the desiderata change in the eleventh hour, as they are all too prone to do.

要是需求在最后的时刻发生了变化，在这上面花点精力的就会显得太值了，事实上也往往如此。

The temperature affects partition of dipotassium glycyrrhizinat but the effect is minor. On the same time pH has major impact on the partition of dipotassium glycyrrhizinat. The coefficient is eight times higher when pH reaches 2. The improved Diamond-Hsu model can be used to correlate the partition coefficient of dipotassium glycyrrhizinat in the system of water/ethanol/isobutanol. The result of Infrared and TG analysis indicate the extraction product has the same characteristic features with dipotassium glycyrrhizinat.

结果表明：体系的初始点越靠近临界点，甘草酸二钾的分配系数越大；温度对甘草酸二钾的分配有～定的影响，但分配系数随温度变化不大；pH值对甘草酸二钾的分配有较大的影响，在pH=2附近，分配系数高出其他位置达8倍；改进的Diamond-Hsu模型可以用于关联甘草酸二钾在水+乙醇+异丁醇体系中的分配系数；红外和TG分析结果表明萃取产物与甘草酸二钾样品的性质特征相同。

The results dicate that there was nearly no difference from hibernation and activity period in all tissures except the liver and skeletal muscle of Elaphe rufodorsata as shown by electrophoresis plot, hibernation was lower than in activity period except that in liver of Erinaceus dealbatus, and LDH4 was not detected in all detected tissues of the three species of snakes.

结果表明：LDH同工酶的电泳图谱只有红点锦蛇的肝和骨骼肌中存在活动期和冬眠期的明显差异，在其余动物两个时期的组织中未表现出明显变化；刺猬的肝脏LDH活性在冬眠期显著地高于活动期，而其余的动物组织冬眠期LDH活性均显著低于活动期；三种蛇类组织LDH4均未见表达。

This system can to many variety circumstances of temperature and degree of humidity for ordering inside the bodega carry on solid hour auto examination, once appearing excrescent phenomenon easy to handle in time, raise to settle a dispute availably past of foresee sex and work efficiency.

这个系统能够对酒窖内多个点的温度及湿度的变化情况进行实时自动检测，一旦出现异常现象便于及时处理，有效地提高了事故的预见性和工作效率。

According to the analysis of reasons of transformer mal-operation in Pingdingshan Electric Power Bureac for years , and according to the present situation of transformer protection studies and applications at home and abroad. This paper points out the shortcomings of discrimination between internal faults and magnetizing inrush, the problems existing in differentiating the slight faults of turn-to-turn in transformer are also advanced. On the base of the electromagnetic characteristics of transformer, the relations between fluxional differential current and voltage of source side analyzed, all the operating states of transformer simulated by EMTP/ATP, the criterion of magnetizing inrush in transformer is got. Through the wavelet analysis of current waveform, using the intense reaction of wavelet transform to the little change of signal, the internal faults of transformer are distinguished by testing local extremum.

本文根据平顶山市电业局历年来变压器保护误动的原因分析，并根据国内外变压器保护使用和研究的现状，指出了现有变压器保护在区分变压器励磁涌流和内部故障方面以及在判断变压器匝间轻微故障方面存在的问题和不足；从变压器电磁特性出发，分析了电源侧电压和电流微分之间的关系，利用电磁暂态仿真程序对变压器各种运行状态进行了仿真，并以此建立了判断变压器是否含有励磁涌流的判据；通过对电流波形的小波分析，利用小波变换对信号微小变化极强的反映能力，通过检测电流的局部极值点来区分变压器运行状态，并作为上述判据的补充。

This means that, in most cases, only a very small part of an object will lie within this area. If we want to observe the object in detail, we have to move the fixation point frequently to make the different parts of the object lie within the central area. In addition, with such a small central area, the separation of foveal and peripheral channel becomes meaningless. Consider all the above aspects, we propose in this thesis a visual computing model based on selective attention mechanism.

针对上述问题，本文的模型引入选择注意机制，并将之建立在非均匀采样表示与处理的基础上，我们提出了一种可以随视觉任务变化的可变结构的非均匀采样信息表示方法，并通过它将后继的视觉处理分成相对独立的中央和周边通道，分别完成对感兴趣物体的识别和注意点的快速转移，后者相当于对感兴趣物体的一个粗定位过程。

Real-time quantitative pcr, immunohistochemistry, dry-wet weight method, histological techniques and haematoxylin and eosin stain were used to detect expression of icam-1, the change of mrna at different time phases, water containing in the brain tissue and the inflammatory infiltration respectively after diffuse brain injury.

Methods The rat models of diffuse brain injury were established by Marmarou's method. Real-time quantitative PCR, immunohistochemistry, dry-wet weight method, histological techniques and haematoxylin and eosin stain were used to detect expression of ICAM-1, the change of mRNA at different time phases, water containing in the brain tissue and the inflammatory infiltration respectively after diffuse brain injury.

Methods: Thirty male SpragueDawley rats were randomly divided into 5 groups, group A 3 days after L5 VRT, group B 7 days, group C 14 days, group D 21 days and group E of sham operation, whose left spine cords were exposed by hemilaminectomy. Rats in each group were respectively perfused with paraformaldehyde and materials were taken from L5 dosal root ganglions and the changes of expression of P2X3 receptor were observed with immunofluorescence staining.

雄性SD大鼠30只，随机分为5组（n=6），A组（L5 VRT术后3 d）、B组（L5 VRT术后7 d）、C组（L5 VRT术后14 d）、D组（L5 VRT术后21 d）模型组和E组，E组仅行半椎板切除术暴露左侧脊髓，分别在各自的时间点灌注取材L5背根神经节，用免疫荧光染色方法观察P2X3受体表达的变化。

CTPI can evaluate the brain homodynamic of cerebral ischemia-reperfusion animal model in living state as a rapid, accurate, non-invasive method, show the cerebral infarction ischemic region's site, size, extent, and has important clinical value for the ultra-acute cerebral infarction to treatment and review.

第二部分CT灌注成像在超急性脑梗死实验中的诊断价值目的：应用CT灌注成像(CT perfusion imaging ，CTPI)技术，观察大鼠超急性脑梗死不同时间点脑血流动力学变化及半暗带(Ischemic penumbra ，IP)的演变，为临床早期诊断治疗提供依据和指导。

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。
