高效能

Nowadays, in the low electron dose condition, the information about 3-4〓 can be recorded on the cryoEM micrograph, and the high-resolution reconstruction using the cryoEM has reached 6. 5-8〓 levels. The reconstruction can reveal the protein α helical and recognise β fold secondary structure. Secondly, it is due to the development in 3D reconstruction method, which can be more efficient to determine the orientation and center parameters. The last but not least, it is also owning to the rapid development in computer science and information technology. Such as, some computational task, which previously must be executed by using super-computer, now can be carried out by personal computer, and at the same time, the network speed and band width of data bus and input/output equipment have increased several times. In addition, the improvement of the high quality graphic displaying is available. All these provide strong support for cryoEM high-resolution reconstruction study.

目前，在低电子剂量的情况下，冷冻电镜照片可以记录到3-4 〓的信息，使用冷冻电子显微镜进行高分辨三维重构工作，已经获得6.5-8〓高分辨率水平的结果，可以分辨出蛋白质的α螺旋、识别出蛋白质的β折叠等蛋白质二级结构；其次是，三维重构算法效能的不断提高，使得对二十面体取向和中心参数计算的可靠性大大提高；再次是，由于计算机和信息技术迅猛发展，例如，以往需要使用大型计算机的计算任务已经可以被一般的个人电脑完成，网络速度、数据总线和硬盘等I／O设备的带宽成倍增长，以及图像显示能力的提高都为冷冻电子显微镜高分辨三维重构技术提供了强有力的支持。

It is an indispensable method to improve family and school education, to create a favorable environment for students.The disadvantages of test-oriented education should be got rid of whilst Quality Education, especially the training of creativity should be energetically advocated to provide the students with a favorable atmosphere for competition. Reasonable goals for achievement should be set, and students should be encouraged to make unremitting efforts, to advance toward higher goals in thecourse of conquering difficulties and savoring success through positive guide and words stimulus. Approachable and imitable examples should also be set for students to make them practice continuous positi

以人为本，改进家庭教育和学校教育方法、营造良好的环境氛围是不可或缺的重要手段，要克服应试教育的种种弊端，大力提倡素质教育，特别是加大创新能力的培养，为学生创建良好的竞争氛围：要设置合理的成就目标，通过正面引导和言语激励，鼓励学生坚持不懈地努力，启发学生在战胜困难和体验成功中不断向更高的目标迈进：要为学生树立可接近和效仿的榜样，让学生不断进行良性的自我强化和替代强化：要帮助学生形成正确的归因，以保持较高的学业自我效能感和成就动机水平；同时要加强师德建设和教师的心理学修养，使教师在具有良好职业道德的基础上，依据心理学规律和学生个体的心理矛盾，在教学实践中因材施教，努力提高自己的教学能力。

In the presently mobile position technology, GPS's position method is one of the best. This method owns high accuracy less than 15 meters, and can be used with GPS chip in the mobile station. But GPS chip with the high price makes this technology difficult to popular. Therefore, the position technology of GSM communication network is attention to the people gradually. TOA or AOA is more often used among position technology, these methods need only the help of the position measuring instrument to attain time and angle for position calculation. They have good position accuracy, but they are also too expensive to popular. Every positioning technology has its bottleneck such as external environment influence, cost and positing efficiency. Therefore, the purpose of this research lies in finding out the mobile station location and does not emphasize the raise of the accuracy and it only uses existing information to finish position action.

在目前的行动定位技术中，以GPS定位技术为最佳，不仅拥有少於15公尺的高定位精确度，更只需在行动端加装GPS晶片即可使用，可惜高价格的GPS晶片使得此技术难以普及化，因此，以GSM通讯网路为主的定位技术逐渐受人们所重视，其中，又以TOA或AOA等定位技术较常被使用，仅透过位置测量仪器的帮助，便可取得定位所需的时间和角度，并且拥有不错的定位精确度，可惜也受到高价格因素的关系难以普及化，而每种定位技术都有其瓶颈存在，不论是外在环境的影响、成本和定位效能上；所以，本研究的目的在於找出行动端位置，即利用现有的资讯（细胞识别码、讯号强度等）来完成定位动作，而非强调其定位精确度的提高。
