On this condition, some useful features have been found in the space domain. Wavelet spectrum estimation method has been used to extract the features in the space domain because the wire rope signal is a kind of none-stable signal. In order to discuss the physical meaning of this method, this dissertation proposes the relationship between Fourier spectrum and wavelet spectrum.

为进一步进行特征提取的需要，根据钢丝信号属于非平稳信号的事实，对信号给出了小波谱估计，以及Fourier谱和小波谱之间的关系和有效的小波谱计算方法，并在对实际钢丝信号小波尺度谱分析的基础上，给出一种信号的小波谱量化的方法，提取了信号的小波谱特征。

At NASA's Kennedy Space Center in Florida, Launch Pad 39A technicians are loading space shuttle Atlantis' two, mass-memory units today.

在佛罗里达州肯尼迪航天中心，发射台39A的技术人员为亚特兰蒂斯航天飞机装上了两个大容量的存储单元。

Historically, transporting cargo to and from the International Space Station has been done primarily by the space shuttle, but it is due to retire in late 2010, or in early 2011 if a short extension is granted.

以往，运送货物往返国际空间站主要由航天飞机包办，但预计其将在2010年底退役，抑或，若其短期延长服役获准，则会在2011年初退役。

Firstly, based on BLOB knowledge, the method transferred 3D color space to 2D angle-mode color space and defined a set of rules of truncated cone to detect shadow BLOB and reflection BLOB. Secondly, the method removed the ghost BLOB from the moving visual BLOB by calculating permanence memory. Finally, the method used a long-time and short-time dual-background model to detect static visual object.

基于BLOB知识，将3D颜色空间变换为&夹角-模差&2D空间后，定义一套圆锥裁剪规则划分出阴影BLOB和反射BLOB；再以一种持久化记忆PM方法判别出鬼影BLOB；最后改进双背景模型检测出静止目标和运动目标。

Divide coordinates in each dimension with the method of half search in the 2L identifier space, at the same time establishing the corresponding next hop set- pointer gauge, so as to reduce the searching space from an entire net to a relatively small region which is partially assigned.

在规模为 2L 的标识符空间上采取折半查找的方法对各维坐标进行划分，并建立相应的下一跳节点集合——指针表，使搜索空间由全网缩减到一个相对较小的指定局部区域。

This paper realizes sentence input method using state space model which integrates Viterbi algorithm into.State space of sentence conversion is described successfully.

提出融入Viterbi算法的状态空间模型，成功地描述了整句转换的状态空间，实现了整句输入法。

Scientists believe that the best way for us to get solar energy is to collect it in outer space by sending a space station there.

科学家们确信，我们获得太阳能的最好办法是发送太空站到外层空间去收集。

Scientists believe that the best way for us to get solar energy is to collect it in outer space by sending a space station there.

科学家们确信，我们获得太阳能的最好办法是发送太空站到外层空间去收集。正在降雨的云块。

It was pointed out that to hunt regional humanistic history landscape elements and build modern characteristic landscape. With examples it was discussed how to raise grade and tasting of public space, to improve green-space landscape design of urban key joints, to build specie diversity and mechanism of tree community self-maintenance. And a project called Shang Capital Square was analyzed in layout features, clever used landscape elements, relative between structure and function.

以偃师市为例指出了县级市在景观绿化方面的合理定位和历史教训，提出挖掘地域的人文历史景观元素，塑造现代特色景观的理念，举例说明如何提高公共绿地的档次与品位，加强城市重要节点的绿地系统景观设计，建立物种多样性与群落自我维持机制，并对商都广场的布局特色、景观元素的巧用、结构与功能的关系作了分析。

And guarantee the space between 2 to 3 mm, at the same time, should guarantee the even space to prevent rubbing the safety brake, the adjustment method is that: relax the rolling wheel screw, adjust the direction of axle, after being adjusted, you should fix the screw.

调整要求保证侧轮和压轮与导轨间的间隙在单侧2-3mm之间，同时还要保证笼顶安全锁两边楔块与导轨架的间隙均匀，以防止正常运行时刮蹭安全楔块，调整方法是：松开导向轮紧固螺栓，调整导向轮中的偏心轴的方向，使间隙让到要求，调整完毕后必须轮紧固螺栓紧固。
