Based on varying process of generator terminal parameters after excitation fault, shortages of excitation protective principle of static stability boundary and asynchronous impedance boundary are analyzed. It proposed that excitation fault research relates to large-disturbance stability. Because dynamic power-angle character of generator after excitation fault is non-sinusoidal, there are differences between dynamic power-angle character and static state power-angle character. So it isn't ideal to protective operation result based on small-disturbance stability and static stability boundary criterion. At the same time, it proposed that asynchronous boundary impedance criterion is a constant reactive power circle moving adown j Xd′. It can ensure complete loss-of-excitation generator measuring impedance enter into the circle, but can't ensure the other condition measuring impedance including impossible losing synchronism enter. So loss-of-excitation protection would be maloperation when system voltage drops short and recovers or generator rejects load.③Based on stability principle, it puts forward setting conditions and calculation method of generator loss-of-excitation protection by direct measuring power-angle.

以励磁故障后发电机端的相关参数的变化为基础，通过对以静稳定边界和异步阻抗边界作判据的两类三种现行励磁保护在原理上存在的缺陷分析，发现：励磁故障是一个大干扰稳定性问题，励磁故障后的发电机的动态功角特性与静态功角特性有很大的差异，已远非正弦曲线，因此基于小干扰稳定性原理、以静稳定边界作判据的保护必然动作不理想；异步边界阻抗判据是一个下移j Xd′的等无功阻抗圆，它可以保证完全失磁后的发电机测量阻抗能进入该阻抗圆，但不能保证完全失磁之外的其它状态不会进入该阻抗圆，因此在系统电压短时下降或发电机突然甩负荷等情况下可能启动该保护使之误动。

So, at present the environment is not special ideal it seems that, basically have reason of the following respects: The first, allied industry lacks a standard, created the malign competition on certain level, arrive to grab for instance a few good stationmaster resource, classics regular meeting is baleful between alliance raise up the price, create oneself profit too low, then, be forced to assure oneself profit through the means such as correction, such practice, it is pair of oneself undoubtedly the challenge of sincere letter, can let itself of stationmaster couplet alliance generate suspicion only, affect stationmaster to be mixed to the view of whole and allied group thereby accept rate, so, between my appeal alliance best and OK build an allied organization, can be opposite the diaphaneity of data, profit margin forehead spends the standard with undertake proper, make the industry gets more healthy progress thereby.

那么，之所以现在环境看起来不是非常理想，主要有以下几方面原因：第一、联盟行业缺乏规范，造成了一定程度上的恶性竞争，比如为了抢到一些好的站长资源，联盟之间经常会恶意抬价，造成自身利润过低，于是，只好通过修正量等方式来保证自己的利润，这样的做法，无疑是对自身诚信的挑战，只会让站长对联盟本身产生怀疑，从而影响站长对整个联盟群体的看法和接受程度，所以，我呼吁联盟之间最好可以建立一个联盟组织，可以对数据的透明度，利润率额度进行一定的规范，从而使行业得到更健康的发展。

Everyday everybody goes on the ave to see fruity sells on roadside, gadgety, fastfood, local speciality, the everybody such as vegetable's common thing is it is be accustomed to sth very, see make a living as a performer even, of beg for food, of panhandle, the edition that buy steel dish no wonder, what see suddenly there are a few to sell a website on roadside is to have a place it seems that too accident, this can be fictitious network product, what also calculate is hi-tech, how can you take the land will sell on booth???

每天大家走在大街上看到路边上卖水果的，小玩意，小吃，土特产，蔬菜等大家常见的东西都是很是习以为常，甚至看到卖艺的，讨饭的，讨钱的，买盗版盘的都不足为奇，突然看到路边上有几个卖网站的似乎是有点太意外了，这可是虚拟的网络产品啊，也算的是高技术，怎么会拿到地摊上来卖呢？？？

Apparently, the approximate controllability doesn"t hold for generally linear parabolic equations with bounded control. It doesn"t hold for the semilinear heat equations presented there,either. Then, it is proved by analyzing its" solutions that no matter how long the time T is , there are targets that can"t be approximated by the solution of heat equation with Dirichlet boundary conditions;If a given target satisying certain conditions can be reached by the solution of heat equation .

本文先针对两个具体的半线性热方程系统证明了控制加约束后系统是不能控的；然后通过分析方程的解，对带位势及Dirichlet边界条件的热方程系统，无论时间多大，都存在不能控的目标；文中还证明了满足一定条件的目标可达。

The non-reference-signal's adaptive digital filter algorithm of multi-sensor data fusion in the course of adaptive filter can be done without reference signals. It can adjust convergence constant automatically, it can also be recurred with real gradient value. Thus the field to apply the adaptive filter is widened, the convergence speed of the adaptive filter is sped up, the weighted disadjustmend is decreased, so that the last error of mean square approaches its minimum value more.

这章研究的基于多传感器数据融合无参考信号的自适应数字滤波算法其在自适应滤波过程中具有不用参考信号与自动调整收敛因子及使用实际梯度值进行递推的特点，这样不仅可扩大自适应滤波的使用范围，而且还使自适应滤波的收敛速度加快有效地减小权失调，从而使最后的均方误差更接近于其最小值。

Hidden Image is an image contains one or more embedded figures The hidden figure merges into typically a busy image such that it does not standout and remains unnoticeable for a while It takes the viewer to focus or some targeted effort to detect the hidden figure and might requires some hint to be able to do so In this paper we provide the technological processes to create the hidden image which normal Texture Synthesis can't be done; According to quantization of background and figure we manage to recolor the quantized color of figure through Luminance Labeling Processing which is base on relationship between background and figure we also manage to remove some parts assigned by user to make our result more natural but can still recognize the figure Finally we present the result using the Texture Processing We believe the proposed system can provide a user-friendly tool to create their own Hidden Image

Hidden Image，中文称为画中有画的艺术；在表现手法上是一们相当新颖且前卫的艺术，其表现风格多种；一般来说，常见手法是将一个或是多个物体以不同型态的方式巧妙的融合在背景当中，观察者在远方观赏整幅画时，并不会觉得特别突兀，而当视觉集中到某一个焦点上时，透过大脑重新组织之后，其隐藏的物体将渐渐浮现出来。本篇论文主要是提供一个完整的流程；根据luminance space区块化后，透过物体本身区块的相互关系，或是物体与背景的相互关系进行Luminance Labeling，并经由Erosion Processing将物体做适当的破坏，最后以贴图方式给予视觉化呈现。相信透过这样的流程，我们将赋予一般普罗大众一套机制去创造出属於自己的Hidden Image。

Accordance with volume of biogas actually using requirement so that actualize supporting facilities, it can keep the pressure contant of biogas using for long time, the floating cover upside of body be pressurized, when the floating cover biogas digester fermenting to produce biogas will drive the soft PVC floating cover rising up with biogas storage, if user make use of biogas in case of biogas stove which the biogas pressure will be drop below in conjunction with floating cover will synchronous drop, when the floating cover has full of biogas which supernumerary of biogas automatic overflow to outside from bottom side of floating cover, it can not be appear with over high pressure thereby cause the tympanites of floating cove burst or biogas pipe burst and never has such phenomenon happen, the floating cove type biogas digester has reliable safe security.

根据沼气实际使用需求用量来做相应配置，可以保持长期在恒压状态沼气气压，浮罩顶部是密封的，当浮罩式沼气池发酵时所产生的沼气使浮罩上升并储存沼气，如果用户在用沼气炉灶用气时沼气压力将随之下降的同时浮罩也随着气压的下降而降低，当浮罩充满沼气时多余的沼气会自动从浮罩底部溢出，不会出现因气压过高造成鼓池、爆裂或爆管现象发生。浮罩式沼气池具有非常可靠的安全保障。
