查询词典 laser disc

A pivotal problem to recognize of the precise position of laser facula has been solved in the process of design work: Firstly the method of background-subtraction is used to eliminate or weaken the affect of background light. Secondly the image threshold segmentation operation and morphologic operation are used to locate the sketchy position of laser facula ; Then the new method of Extracting Edge are designed based on character of laser facula , by using this method in the search area the edges of laser facula can be extracted effectively; At last the optimum picture of laser facular is selected by using the triggering function of hardware and function of software. The exact result can be obtained only by image processing to optimum picture.

在设计过程中解决了精确确定激光斑中心位置这一关键问题：首先利用减背景法，消除或减弱背景光的变化对确定激光光斑中心的影响；再对减完背景后的图片进行阈值分割和二值化处理以确定激光光斑的粗略位置；根据本文激光光斑的特征，设计了一个有效的边界提取算法，对指定区域进行提取激光光斑边界操作，精确的确定激光斑中心位置；最后利用硬件的触发功能和软件编程实现了激光光斑最佳图片的判读，只有对最佳图片进行图像处理得到结果才是准确的。

Burner to provide the "analog recording" and "burn" the difference is whether or not the order of laser beam shot, while others are exactly the same operation, that is to say,"burn simulation" to test whether or not the source of the normal CD-ROM, hard drive speed is fast enough, the remaining disk space to burn, such as the adequacy of the state of the environment, but can not burn the disc to be tested if there is a problem and the burner's laser to read and write the first match power with the disc and so on.

刻录机提供的"模拟刻录"和"刻录"命令的差别在于是否打出激光光束，而其它的操作都是完全相同的，也就是说，模拟刻录＂可以测试源光盘是否正常，硬盘转速是否够快，剩余磁盘空间是否足够等刻录环境的状况，但无法测试待刻录的盘片是否存在问题和刻录机的激光读写头功率与盘片是否匹配等等。

When the moment made by material on turning plate is greater than that of heavy hammer and rocker, the disc will open adown to discharge. After discharge the moment made by heavy hammer and rocker will drive disc close quickly to realize locking air. Because the structure of valve is two-layer, there is always one disc in pipe that is in close condition. So it can discharges and lock air at the same time.

即当作用于翻板上的物料产生的力矩大于重锤摇杆产生的力矩时，阀板打开卸灰，一旦积灰卸去后，重锤与摇杆产生的力矩使阀板迅速关闭，实现锁气是由于本阀采用的是双层结构，因而使管道上阀板始终有一个是关闭状态，可使卸灰与锁气同时达到目的。

Selected anastomosis site:The site for the attempt at anastomosis creation was chosen at least 2-3 disc diametersaway from the optic disc or 1 disc diameter peripheral to the occlusion site in eyes with bruch retinal vein occlusion, and a large underlying choroidal vein by showing in ICGA, usually in the inferior fundus.

激光吻合：在选定的吻合部位，用选定的高能量激光先击射邻近的＊＿Ch膜，接着是静脉壁本身，Bruch膜破裂的疑似迹象，为一汽化泡，当静脉壁破坏时有微量的出血。37例RVO共做了86个吻合点，所用的激光参数为：光斑直径50p，曝光时间 0.l秒，使用绿光最多 63个点（72％），功率 800～900mw，少数用氟红、氟黄及Nd：YAG激光。

Methods: Forty-five SD rats were divided equally into SMT group, cervical intervertebral disc cataplasia model group and normal control group. Three months later, the morphologic changes of intervertebral disc were observed to determine the proteoglycan contents and the apoptosis rate of the intervertebral disc cells.
