Aimed at the problem of choosing the initial value when the Newton method is used to compute the controlling unstable equilibrium point, a practical and rigorous solving scheme was presented: by identifying the controlling load bus of the given fault, and using the Thevenin equivalent circuit to represent the rest of the system at the state of the post disturbance stable equilibrium point, using the steady equivalent circuit to represent the induction motor in composite load, and then using the torque characteristics of induction motor, a point near the CUEP is gained to be the initial value. The second order normal forms was used to approximate the stable manifold of CUEP, and the local approximating boundary of the region of attraction of the post disturbance stable equilibrium point was gained. Then just by simulating the state of the system at the fault clearing time, the transient voltage stability of the system could be determined.

针对采用牛顿法求取故障后系统主导不稳定平衡点(controlling unstable equilibrium point，CUEP)存在的初值选取难题，提出一种实用但不失严谨的解决方案：通过识别给定故障的主导负荷母线，对主导负荷母线以外系统由故障后稳定平衡点处的状态进行戴维南等值，对负荷中感应电动机部分采用其稳态等值电路，再由感应电动机的转矩特性求得CUEP附近的一个点作为近似的CUEP，以此为迭代初值可靠求得CUEP；采用二阶正规型来近似CUEP的稳定流形的方法求得近似的局部吸引域边界；由仿真得到故障清除时刻系统的状态并根据该状态是否位于吸引域内判断系统的暂态电压稳定性。

It is plain enough that a computer hard drive itself, the hard disk at startup, first of all, hard to read the contents of master boot area, the hard drive partition information is read into the cache, then the basis of information sent by the host to read goal of the operation of the Boot partition information, the target partition to decrypt the content guide information, and then the next table to read FAT and root directory, so that the target partition can read any file.

说得再明白一点，硬盘自身也是一部计算机，硬盘在启动时，首先要读取硬盘主引导区的内容，把硬盘的分区信息读入缓存，再根据主机送来的信息去读取目标操作分区的引导区信息，把目标分区的引导信息内容进行解密，再接下来去读取FAT表和根目录，这样就可以读取目标分区中的任一文件。

First ,it carry on the demonstration analysis to the efficiency of Chinese stock market , judge present efficiency state , then use relevant analysis technology and T examine law in econometrics to analyze the relevant relationship between split share structure and the efficiency of Chinese stock market , and then ,put qualitative analysis on the reason of low efficiency of Chinese stock market and the uncertainty change of Chinese stock market after reform , to investigate the influence degree on the efficiency of Chinese stock market by split share structure .

第三章为股权分置改革对股票市场效率的影响分析，先对中国股票市场效率进行实证分析，判断中国股票市场目前的效率状况，然后运用计量经济学中的相关分析技术和T检验法，对股权分置制度与中国股票市场的效率进行了相关性分析，再从对中国股票市场低效率的成因、股权分置改革后中国股票市场不确定性变化的定性分析中，考察股权分置改革对中国股票市场效率的影响程度。

Sometimes he was beaten till he could hardly stand, then flung like a sack of potatoes on to the stone floor of a cell, left to recuperate for a few hours, and then taken out and beaten again

有时他给打得站不住脚，像一袋土豆似的掉在牢房里的石头地上，歇息了几个小时以后，又给带出去痛打。

Onetechnique, surprise: Single when and if other people, have a fixed-step (O-step word, S word step backward in a straightline, etc.) should be close to the enemy in time for change, change for about 1 second left, To do all of a sudden, the mainpurpose is to allow the enemy lost the ability to reflect, too late to dodge, and then re-knife to cut them to death, whichis the most successful results, if the two sides into a short-range combat knife, then use the knife should be light.

技巧一，出其不意：在单刀时如果与别人对上，自己有一个固定的步法（O字步，S字步，直线后退等）则要在敌人接近时进行改变，改变时间约1秒左右，要做到突然，主要目的是让敌人失去反映能力，来不及闪躲，然后以重刀一刀毙之，这是最成功的效果，若双方陷入短距离刀战，则使用轻刀应对。

IL-1βmRNA expression in the developmental brain in Wistar rat: IL-1β mRNA in hippocampus, cerebral cortex and subcortex was detected by postnatal day 1 and gradually increased with development, reached a peak at postnatal day 21, and then gradually decreased to lower level at adult; In P77PMC rat, IL-1β mRNA expression was similar to Wistar rat before postnatal day 14, then gradually increased and surpassed Wistar rat at postnatal day 28, reached a peak in adult.

原位杂交显示谷氨酸诱导Wistar大鼠惊厥和P77PMC大鼠听源性惊厥后脑内IL-1βmRNA表达情况。结果发现，两种不同惊厥模型大鼠惊厥后脑内IL-1βmRNA表达存在明显的差异。谷氨酸引起惊厥诱导脑内皮层、海马和丘脑IL-1βmRNA表达增高的程度远较P77PMC大鼠听源性惊厥为低，而且惊厥后IL-1βmRNA表达增加较慢，于4-8h达高峰，而听源性惊厥可于惊厥后2h迅速达高峰。但两种形式惊厥诱导脑内IL-1βmRNA表达最高的部位均是海马。

If you want to make a change within a submodule and you have a detached head, then you should create or checkout a branch, make your changes, publish the change within the submodule, and then update the superproject to reference the new commit

如果你在子模块中进行了变动并且你处在剥离的头上，那么你应该创建或者是提取一个分支，作出你的更改，将这些更改发布到子模块中，并更新上级项目到一个新的交付引用。

In global mode, annular omnidirectional images are captured by using skip subsampling mode to guarantee high frame rate, and then unwrapped to cylindrical panoramic images containing global scene information of 360 degrees. In local mode, the location and size of sampling window of image sensor are reconfigured according to the position of interested region, thereby only a corresponding rectangle region of omnidirectional images is captured by using pixel-by-pixel mode, and then unwrapped to a high- definition local perspective image of the corresponding view angle. Finally, a hardware design based on DSP+FPGA is presented.

在全局模式下，为保证采集帧速率，使用行列跳跃模式采集完整的环状全向图，并将其展开为包含360°全局信息的柱面全景图像；在局部模式下，根据感兴趣区域的空间位置设置采样窗口大小及位置，以逐像素采样模式只采集全向图中相应的一块矩形区域，并将其展开为对应视线方向上高清晰度的局部透视图；最后给出了DSP+FPGA结构的系统硬件设计方案。

Their mutual superposition, and then after LMS adaptive algorithm, and then compare their results.

它们相互迭加，再经过LMS自适应算法，再比较它们的结果。

But we don't care about Battlegrounds.

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
