Feature of principal lines spatial distribution: detect the principal lines through edge detecting technology, and then divide the image of palmprint into blocks with same dimension, compute the mean and variance as feature; Feature of palmprint direction: divide the image into sub-images; compute the max angle of projection and coordinate of each sub-image, which stand for the direction and location of the line on the palm; Feature of moment invariants: compute the moment invariants of each sub-image and the whole image as feature.

掌纹主线空间分布特征：利用边缘检测技术检测出掌纹的主线，将图像分割成相同大小互不重叠的子图，提取每一个子图的均值和方差作为特征；掌纹线方向特征：将图像分成不重叠的子图，利用Radon变换求出每一个子图的最大投影角度和坐标，也就是子图内掌纹线的方向和位置，构造特征向量；掌纹不变矩特征：提取图像整体和分割后的子图的不变矩作为特征。

Boston, MA ( Sept. 17, 2007)— InHand Electronics, Inc., a leader in handheld and wireless device platforms for OEMs, the Natick Soldier Research Development and Engineering Center and Army Research Lab, Sensors Electronic Device Directorate, today announcedat the Embedded Systems Conference the completion of the first general-purpose, military-grade PDA utilizing low-power, flexible display technology.

波士顿，麻省( 9月17日2007)—掌上电子产品公司，原始设备制造商掌上和无线电设备平台的领军人，内蒂克战士研究发展和工程学中心和陆军研究实验室，传感器电子设备董事会(Adelphi， MD)，今天在嵌入系统会议上宣布已率先获得民用和军用级低耗、灵活的掌上电脑显示技术。

In order to decrease space, speed transporation, an image must be compressed. There are two methods: revertible and unrevertible.

为了减少数据存储量，节约传送，处理时间，必须对图像数据进行压缩，这些方案可分为两类，即可逆型和不可逆型，对于掌纹图像，因为我们要掌纹图像的细节，如果用不可逆压缩方法，就会丢失掌纹细节信息，因此，我们只能用可逆型压缩方法。

In the second part, other types of chiral selectors were used for enantioseperation of thioridazine in order to compare with the MI-S-b-CD system.

第二部分则以其他种类的环糊精等对掌选择剂来分离分析物的对掌异构物，探讨不同对掌选择剂对分析物对掌异构化动态学的影响，与MI-S-b-CD分离的结果做比较。

Methods:Fifty-six patients with metacarpal and phalangeal fractures who were reviewed in the study were divided into two groups:Group A and Group B.Thirty-two patients in Group A were treated with open reduction,Kirschner internal fixation and postoperative plaster splint external fixation.Other 24 patients in Group B were treated with open reduction,Mini-plate internal fixation,without any external fixation.

回顾分析经完整随访的56例掌指骨骨折患者的治疗和康复情况，A组：32例掌指骨骨折患者予以行切开复位交叉克氏针内固定接骨术，术后石膏夹板外固定；B组：24例掌指骨骨折患者予以行切开复位微型接骨板内固定接骨术，术后未用外固定。

Methods From Aug1997to Sep2003,according to the injuries of interphalangeal joint,we grafted the metatarsusphalangeal joint and proximal phalangeal joints of2th toes for reconstructing it.

目的 观察第2足趾跖趾关节与近趾间关节移植同时重建掌指关节与近指间关节的临床疗效方法我们于1997年8月～2003年9月，根据掌指关节与近指间关节的损伤情况，设计应用第2足趾跖趾关节与近趾间关节移植同时重建掌指关节与近指间关节。

A new method based on the Maximum Effective Circle is presented using the characteristic of the palmprint that the uniqueness and the invariance to the rotation can be obtained by obtain the datum point.

因此，本文在学习掌纹识别主要技术的基础上，重点分析研究了掌纹识别技术中的不变性特征提取技术，并利用掌纹识别技术具有可通过基准点对掌纹进行定义从而获得旋转不变性和唯一性的特点，在掌纹图像的不变性特征提取方面提出了一种基于最大有效圆的定位方法。

Raising its fruit yields, breeding excellent varieties on the family or the clone by the heredity improvement that provided the plentiful produce the steady produce and high efficiency, those were keys of biodiesel industry to study and develop for the future.
