扫描

Using normal distribution transform probability model to represent a laser range scan.Not need features corresponded,but transform the discrete scan date to the piecewise continuous and differentiable probability density function,and using Newton's algorithm to optimize scan matching,so can build the 2D global map.

利用正态分布转换概率模型来表示激光扫描，不需利用特征对应，而是通过将扫描得到的离散数据点转换成分段连续可微的概率密度函数，并利用牛顿优化算法来进行扫描匹配，从而建立2维全局地图。

In the scanning process, we have completed the Hebei Bureau of Press and Publication of all the historical archives of microfilm and digital conversion work, as part ofShijiazhuang office document scanning and PDF format conversion job, etc.; we have to scan their own processing software.

An optical scanning device for scanning tracks of an optical record carrier using a radiation beam, the device including an optical head ( 16 ), defining an optical axis, for converging the radiation beam to a spot when scanning the record carrier; and a rotary arm ( 2 ) for moving the optical head across the record carrier.

一种光学扫描设备，用于利用辐射光束扫描光学记录载体的轨道，该设备包括光头(16)，其限定了光轴，用于在扫描记录载体时将辐射光束会聚为光点；和旋转臂(2)，用于在记录载体上移动光头。

Based on the vector law of refection in optics, the scanning error′s academic formula is educed.

分析表明，用激光及其扫描装置建立光学基准面时，扫描误差是不可避免的，这种误差不加补偿，则最终将引入基准光学平面影响基准精度，进而降低参数的评定精度；借助于所推导的误差补偿公式，是可以补偿这种误差的，这对于建立高精度的扫描基准平面具有理论指导意义。

It is reported, safe scanning undertakes to the computer when MSN protects aegis to include Messenger to start, 500 endangers MSN possibly virus with foregone scanning and virus of 70 thousand multinomial popularity; When receiving a good friend to send a document, undertake to the file scanning and should appear when new potential MSN virus undertake in time remindful waiting for a function to the user.

据悉，MSN保护盾包括Messenger启动时对计算机进行安全扫描，扫描已知的500项可能危害MSN的病毒以及7万多项流行病毒；接收好友发送文件时对文件进行扫描以及当出现新的潜在MSN病毒时及时对用户进行提醒等功能。

A scale factor of 150% means that the scaled dimension is 1.5 times that of the original dimension.

需要扫描标志来决定扫描的方向和扫描的目标。

Independent factors associated with radiation dose were patient weight (relative effect on DLP, 5%; 95% confidence interval , 4%-6%), absence of stable sinus rhythm (10%; 95% CI, 2%-19%), scan length (5%; 95% CI, 4%-6%), electrocardiographically controlled tube current modulation (–25%; 95% CI,–23% to –28%; applied in 73% of patients), 100-kV tube voltage (–46%; 95% CI,–42% to –51%; applied in 5% of patients), sequential scanning (–78%; 95% CI,–77% to –79%; applied in 6% of patients), experience in cardiac CT (–1%; 95% CI,–1% to 0%), number of CCTA s per month (0%; 95% CI, 0%-1%), and type of 64-slice CT system (for highest vs lowest dose system, 97%; 95% CI, 88%-106%).

与放射剂量有关的独立因子有：病人的体重（对DLP的相对影响，占5%）；稳定窦性节律的阙如（占10%的影响）；扫描的长度（扫描长度增加1厘米相当于DLP增加5%）；应用心电图控制的管电流调制（导致DLP降低25%；用于73%的患者身上）；100-kV 管电压（使DLP降低46%，应用于5%的患者）；序贯扫描（降低78%；应用于6%的病人）；对心脏CT的经验（降低1%）；每月CCTA的数量；64层CT系统的类型

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
