80 GeV where many charm resonances exist according to the prediction by some models.

我们在第一轮R值扫描的6个点都是远离共振区，而第二轮扫描的大部分点都集中在3.70-4.80 GeV。

For distorted book image under random twisted status,by comparing its margin-gray-curve data with the stored margin-gray-curves data,a group of multinomial coefficients whose corresponding twisted status is proximal to that of the to be corrected image can be selected out to determine automatically a group of distortion parameters that is suitable for distortion correction.

任意弯曲状态下的书籍扫描图像可以在数据文件中搜索到与其最接近的弯曲状态，并利用对应的多项式系数自动求得最佳畸变参数，用于图像的畸变校正实验，获得了较好的校正效果，最大误差由未校正时的63%下降到了4.4%。这使得在无需人工测量或调整畸变参数的条件下可自动校正书籍扫描图像。

Scanning cigarette cases with hand-held wireless scanner in distribution station was laboursome and mistakable, the problems of low scanning efficiency and high error rate were solved by setting fixed scanners on two sides of a distributing conveyor combined with RS-232 serial communication and OPC technologies.

使用手持无线扫描仪对发货的成品烟进行扫描，该方式劳动强度大，且容易出错。为此，通过在成品发货输送轨道两侧安装固定扫描器，利用RS-232串口通讯技术、OPC技术等解决了传统发货扫描效率低、易出错的问题。

Hand-held scanner, was born in 1987, when the use of relatively wide, hand-held scanner to scan a narrow format, difficult operation and accurate image capture, scanning the results would be worse.

手持式扫描仪诞生于1987年，当时使用比较广泛，手持式扫描仪扫描幅面窄，难于操作和捕获精确图像，扫描效果也差。1996年后，各扫描仪厂家相继停产，从此手持式扫描仪销声匿迹。
