The double - color method and theory for stereodisplay of the torpedo ' s trajectory are presented in this article . program which is using the programming language of visual c + + 6 . 0 + mfc + opengl has been compiled . in this program , torpedo can be displayed in stereodisplay mode , which can be controlled adapting to the changing of time and space 本文提出了鱼雷弹道双色立体显示技术,系统的介绍了鱼雷弹道立体显示的原理和方法,并采用visualc + + 6 . 0 + mfc + opengl软件结构编制了相应的程序,使鱼雷最终能够直观的,以图象信息表示出其随时间和空间变化过程,即以立体图象呈现在研究者面前,从而能够更为方便地模拟和计算,对鱼雷弹道的研究和设计具有十分重要的意义。
And collecting the image of the damage instance in the sample of pmma in real time on line , we get the surface crazing damage density under different time and different stress passing the image dispose of a software , and giving out a changing rule that the change of the sample of pmma ' s surface crazing damage density follow the change of time and stress 对pmma试件银纹损伤情况进行在线实时的图像采集,经图像处理软件的分析,得到了pmma试件在不同时间和不同应力水平下的银纹损伤面密度,并给出了pmma试件银纹损伤面密度随时间和应力的变化而变化的规律。
However , there also exist more unsuitable behaviour and thinking : the fitting degree is small and low ; the expectation about future isn " t stable and uncertain , their psychological pressure is great ; contingency comes into being , farmers can " t be sure of the happenings , they have to follow others and think they were living happily in the old days an d now they aren " t ; cultural collision is great , they feel hard to follow the change of time ; the system is changing . their living pressure is large ; the felling of living on the edge is obvious with the emergence of gap of the rich and the poor ; they feel the human feeling is disappearing and become alone in the competing 但在经济体制改革中,农民表现出的不适应性行为与心理更多,既:对市场经济改革的适应程度比较低;预期不确定、不稳定,农民心理负担加重;偶然性出现,农民难以准确把握未来,怀旧、从众行为与心理难以避免;多元文化冲突加剧,农民心理适应难度大;体制转换,农民生存压力增大;穷富差距拉大,农民边缘感增强;竞争加剧,农民人情淡漠感、孤独失落感加大等。
The pmma ' s craze damage is observed on line in different temperature and invariable load , which show that the change pricks up with the increase of time and temperature . with the disposal of the image , we get a changing rule that the change of the sample of pmma ' s surface crazing damage density follow the change of time and stress . then the data from experiment is to match in non - linearity , pmma ' s density of crazing damage changing with time and stress is available 对pmma在恒定荷载作用下,不同基温下的pmma银纹损伤进行了实时在线观测,结果表明: pmma试件的银纹随持荷时间增加,而且随着温度的升高,可以加剧这种银纹随时间的变化;经图像处理,得到了不同基温下、不同应力水平下, pmma试件银纹损伤面密度值;进而,对所得数据进行非线性拟合,得到pmma试件银纹损伤密度随时间演化规律,以及应力水平依赖性; 3
