This article , according to the common digital keyboard on the mobile communication equipment , make essential research for windows ce - embedded operation system in chinese character input technology and realize with digital keyboard . using tree - like structure that has the space complexity o ( n ) and the time complexity of o ( n ) when searching to store chinese information . chinese input method applying this kind of store technique in chinese table has the quality of high input speed and low memory space 本文就根据移动通信设备上常见的数字键盘，为windowsce嵌入式操作系统在汉字的数字键盘输入技术及其实现方面作了必要的研究；并使用了一种在查找时空间复杂度为o ( n ) 、时间复杂度为o ( n )的树形结构来存储中文信息，使用这种存储技术作为码表内存存放方式的汉字输入法具有输入速度快、占用空间少的优点。
Compared with currently fire control system , apsse has such characteristic as : highly precision , complex construction , high technique , etc . so this thesis expatiated in detail on the measuring theory of apsse , emphases on the discussion of system error and random error of apsse , deduced the three axis error of apsse usign the coordination transformation methods , provided the applying base for the measuring error equation of apsse . in this paper , we emphases on expatiating the basic theory of usign space coordination transformation in the measuring error equation of apsse 因此，论文采用了空间坐标变换方法分析机载光电跟踪测量设备在对目标进行测量、定位时空间坐标转换关系，推导出从中心地平坐标系到目标坐标系的变换矩阵，在此基础上首先建立机载光电跟踪测量设备的无测量误差的位置传递方程和机载光电跟踪测量设备的含有测量误差的位置传递方程，为利用蒙特卡洛法分析机载光电跟踪测量设备的测量误差奠定了理论基础。
The in - group conflict among roller skaters was investigated with responders ' attitudes toward various types of roller skaters encountered and their perceived conflict in terms of the 16 interference items ; skill level was investigated with self - reported skill level based on the course contents posted on the website by the chinese roller skate association ; space use types include linear space and plane space 本研究之内团体冲突是调查受访者在遭遇各类直排轮活动参与者时之态度，以及受访者针对16项直排轮内团体冲突项目所知觉到的冲突程度；活动技术水准是调查受访者根据直排轮协会所拟订之进阶课程内容评估个人的技术水准；空间使用型态乃调查受访者从事直排轮活动时空间使用的主要型态，包含线性及平面空间两类型。
