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。
