查询词典 moving picture

Due to the mobile sensor is expensive and moving will consume a lot of energy. We used a small part of mobile sensor and most part of static sensors to meet the demand of k-coverage of three-dimensional network, and we have analysis the ratio of them is 1/(2πk^1/2. To achieve k-coverage, we have received the maximum moving distance for mobile sensor is O(log^1/3 in a network with a size of L . At last, we established a mathematical mobility model for mobile sensors, and converted the sensor redeployment for k-coverage into maximum network flow problem, and proposed a distributed relocation algorithm and verified it through experiment simulation.

This is a language where 'cleave' can mean to cut in half or to hold two halves together; where the simple word 'set' has 126 different meanings as a verb, 58 as a noun, and 10 as a participial adjective; where if you can run fast you are moving swiftly, but if you are stuck fast you are not moving at all; where 'colonel,' 'freight,' 'once,' and 'ache' are strikingly at odds with their spellings.

在英语里，"劈"既可以是指一切为二的意思，又有把两样东西粘合在一起的意思；一个简简单单的"SET"，作动词时，就有126种不同的意思，而作名词用时，又有58个意思，作为分词形容词是，则又有10种意思了；英语里，如果说你跑地快，说明你移动的迅速，但是快这个次在与粘用在一起时，这时的快就不是原来那个意思了；名词colonel、 freight和once则与它们的拼写形成鲜明的对比。

Along with increment of mean photon number, there is no change in the oscillation period of the squeezing curve, but its scope increases obviously and its stability begins to reduce; when the mean photon number and the field mold structure fixed, the speed of moving atom has a great infection on the extent and period of the radiation squeeze. With the speed of moving atom increasing, not only the complete squeezing effect would be archived, the stability would also enhance.

随着平均光子数的增加，压缩曲线的振荡周期没有明显的变化，压缩曲线的振荡幅度明显增大，压缩的稳定性变小；在平均光子数和场模结构参数一定时，原子运动速度对光场压缩的深度以及压缩周期影响程度较大，增大原子运动速度，不但可以实现完全压缩光场，而且压缩的稳定性得到提高。

The small hole of the optical inducer of the traditional second-generation optical mouse used for receiving the images faces downwards, and corresponding light sources (including photoelectric diode and laser diode), optic lens and photosensitive holes are arranged at the lower part of the mouse; therefore, moving the whole mouse is a relatively convenient method for generating displacement of the mouse pointer; oppositely, the small hole of the optical inducer used for receiving the images faces upwards and corresponding light sources, optical lens and photosensitive holes (7) are arranged at the upper part of the mouse; matters on the upper surface of the photosensitive hole (7) can be moved so as to lead the mouse pointer to generate the displacement, while the moving signal transmitted by a photoelectric conversion device must be reset so as to comply with the integrated mouse of the invention.

传统的第二代光电鼠标的光学感应器接收图象的小孔是向下的，对应的光源(包括光电二极管，激光二极管)、光学透镜和感光孔都是在鼠标下部分，这样要想鼠标指针产生位移较方便的方法就是移动整个鼠标；相反，光学感应器接受图象的小孔向上，对应的光源、光学透镜和感光孔(7)在鼠标上部分，要使鼠标指针产生位移就只需移动附在感光孔(7)上面的物质，但必须重新设置光电转换装置传出的移动信号，以符合本发明。
