In this paper , cj20 - 25 alternating contactor is the study object . after optimization design to it , the sample has been made . the experimenters of fuzhou university tested it dynamic characteristic 本文以cj20 - 25型交流接触器为主要研究对象,采用多目标优化设计技术对其电磁机构进行了优化设计,根据优化结果加工出了优化后的接触器样品,并请福州大学有关试验人员对样品的动特性参数进行了测试。
In formerly static strength tests , no attention was paid to the process of test load . according to their experiences , experimenters adjusted pressure in actuator only by hand to control the test load value and the load value was read from instruments 早期的静力试验对加载过程没有严格的要求,所以当时的液压加载方式由试验人员直接调整供油压力,改变液压缸内的油压,控制活塞杆输出的集中力载荷。
Even if experimenters bounce the beams to and fro to increase the effective length of an interferometer ' s arms to more than 100 kilometres , the expected difference in length between the two beams ' paths still amounts to less than a hundred - millionth of the diameter of a hydrogen atom 尽管已经让激光束反复反射来使激光干涉管臂的有效长度增加到超过了100公里,但在光路路程之内,两束光波长差仍小于氢原子直径的一亿分之一。
Recently , the chairman of singapore sports council ng ser miang suggested that special classes be set up in schools to help bring up young sportsmen and sportswomen . he is a great experimenter , and i applaud his bright idea . it will be a good start to map out an experimental field for lots of budding athletes in singapore 近闻体育理事会主席黄思绵谈关于开办体育高才班的设想,我想为这个试验者打打气,开辟一块为新加坡多出快出体育人才的试验田的出发点是正确的,即使在试验中有不足也是必然的,不必惊慌。
The software has been designed with c and assembly language , and has compiled some head documents and many libs for experimenters . in order to use the experiment platform better , the experiment platform has been combined with virtual instruments , and the software to be used in windows operating system has been designed with labwindows / cvi language , furthermore , introduced how to build the function lib defined by ourselves with labwindows / cvi 软件部分用c和汇编语言设计了软件例程,编写了头文件和库函数提供给实验者使用,同时为充分利用实验平台,又将实验平台与虚拟仪器结合起来,用labwindows / cvi语言编写了windows的应用程序,介绍了如何用labwindows / cvi语言编写自定义库函数。
Its function module primarily include data acquisition data display data processing and giving grades to experimenters etc . the interface of this software is not only porcelain but also simple and convenient to operate all test data is simultaneously displayed in real time , so , shortcomings exiting in the early test equipment such as test data displaying in share time and serially oneness and no intuitiveness of the displaying data are avoided 软件的人机界面精美,使用操作简单方便。数据的并行实时显示克服了原测试仪中串行分时显示、数据单一和不直观的缺点。测试的原始数据、处理后的数据及成绩评定的结果都以电子文档的形式进行存储。
The latter will be given options and allowed time to try them out , which is long enough for at least one test interval . people will not jump rashly to the conclusion that something must be wrong out there , and the experimenters will not be under pressure . such experimental fields are meant to find out where shortcomings are and what can be done as a remedy 在试验田里大家包括媒体允许试验者出错,给他建议给他时间,而这个时间一定是一个试验周期的时间,看官千万不要一语定性,加以否定,造成试验者承受巨大的舆论压力,因为开辟试验田就是以找出不足,加以改进为目的的。
Then the process of making optimal bidding strategy is introduced by using an example . in another bidding experiment , we find out experimenters " risk preferences through psycho test , and then we compare these data with bidding data gathered in the experiment . we find the risk preference and the price adjustment have some relation and it ' s worth studying further 随后的部分介绍了考虑报价人风险偏好问题的最优策略制定过程,在另一个竞价实验研究中,引入了行为经济学的研究方法,通过心理学测试结果以及实际报价数据之间的比较观察,发现决策人风险度偏好曲线和决策人报价调整量之间有着相同的变化规律,这一发现为研究决策人风险偏好问题开辟了新的思路。
Remote experiments provide experimenters with experimental resource and experimental methods shared by them , which can improve the quality of experiments . embed system refers to computer systems based compuer technology and application . they are specially designed to conform to extrem requirments in function , reliability , cost , bulk and power 利用远程实验,广大实验者可突破传统实验在实验资源(实验设备、场地和时间等)和实验方法(统一进度、集中式等)方面的限制,实现优秀实验资源和实验方法不受时间和空间等约束的共享,提高了实验质量。
The vrl based on desktop vr use x3d technology to produce realistic three - dimensional virtual scene , and can enable experimenter to sense and operate various kinds of virtual object , to interact with the scene real - timely and mutually . therefore it can achieve better teaching effect than the existing planar virtual experiments . this paper analyzed the virtual laboratory and virtual reality 基于桌面式虚拟现实技术的虚拟实验室利用建模技术生成三维仿真的虚拟实验场景,让实验者沉浸于虚拟场景之中,并通过与实验场景进行实时的交互感知和操作实验对象,完成类似于真实环境下的实验操作过程。
