In order to preserve more details while erasing mixed noise, a new algorithm based on the structure of modified trimmed mean filter was proposed. Characters of the new one are: 1 replaces the median filter with center weighted median which shows better performance in preserving details; 2 uses the filtering result to estimate the deviation of Gaussian noise. The estimating result is used to change the filter parameter, so the new algorithm is robust.

为了在滤除退化图像中混合噪声的同时能更好地保护图像的细节，文中提出了基于改进均值滤波结构的新算法，其特点为： 1）用中心加权中值滤波算法替代MTM 方法中的中值滤波算法以更好地保护细节； 2）提出了一种直接利用滤波结果来估计混合噪声中高斯噪声方差的方法，估计的结果被用于滤波器系数的调整，使得新算法有很好的鲁棒性。

Ion of the setting, the rest of the account is showing how, over the first three days, the problem of the earth's formlessness is solved as God shapes the creation, and how, over the next three days (and perhaps beginning on the third day, if you count the plants), the earth's emptiness is replaced by the various created things that God places in the newly shaped regions.

从这个场景的叙述，其余的记载显示，头三天中，地空虚的问题被解决了，上帝塑造了地﹔以及，在接下来的三天中（如果算植物，第三天大概也包括在内），混沌的地被各种被造物所填满，是上帝把它们安放在已经造好的区域里面。

ABSTRACT: The UAV navigation system's performance is improved through embedding the geography information model that can process the vector map data in the system by using MapX, In this paper, how to navigate and plan the UAV flight course in the vector map is investigated. The basic control and operation for vector map in the geography information system is introduced, and the flight course is designed and modified in the map. In addition, 2D vector map can't orient UAV in 3D space, so the altitude model is added in the UAV navigation system to realize 3D orientation by integrating 2D vector map with altitude plot. The simulation results in the UAV simulation system indicate that the navigation system can monitor and control UAV efficiently and intuitionally.

V2：撒但这样对他最亲近的伙伴说着，把他的头抬出火焰的波浪上面，两只眼睛，发射着炯炯的光芒，身体的其他部分平伏在火的洪流上，又长又大的肢体，平浮几十丈，体积之大，正象神话中的怪物，象那跟育芙作战的巨人泰坦，地母之子，或象百手巨人布赖利奥斯，或是古代那把守塔苏斯岩洞的百头神台芬，或者象那海兽列未坦，就是上帝所创造的一切能在大海洪波里游泳的生物中最巨大的怪物：据舟子们说，他有时在汹涌的挪威海面上打瞌睡，常有小舟夜航而遇险的时候，以为他是个岛屿，抛锚扎在他的鳞皮上，碇泊在他身旁的背风处，在黑夜的笼罩中等待姗姗来迟的黎明。大魔王就是这样横陈巨体，被锁在炎炎的火湖上面，既不能起立，也不能昂起头来，但由于那统治万汇的天神的意志和他的洪量，让他自由地得逞阴谋，他心想危害别人，却终于加重自己的罪行，刑上加刑，让他懊恼地看见自己一切的恶意怎样在他所引诱的人身上带来无穷的善意、恩惠和怜悯，而在他自己身上却招来了三倍的慌乱、惩罚和报复。

The problems are due to the trammels of traditional teaching ideology and practice of the teachers,lack of variety in training styles,the imperfection of the standards of new curriculum,and the restriction by the exterior circumstances for the reform.

不切实际地夸大取得的成绩，盲目乐观，粉饰太平，就不可能正视和改变现实中存在的问题；一味地强调改革中的问题，看不到发展中积极的一面，则会悲观失望，进而消极应对甚至拒绝新课程。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.
