| 1. | The way to supervise and measure automatically the change of attenuation of multi - optic fibers 多根光纤衰减变化自动监测的实现 |
| 2. | The problem that ballistic coordinates of assembly firing were measured automatically was resolved in a cumulate holes image by the technology of image processing 摘要利用图像处理技术针对累计弹孔成像,解决成组射击弹道坐标的自动测量问题。 |
| 3. | By this device with an intelligent system composed of at89s52 single chip microcomputers , the period of a simple pendulum and the gravity acceleration can be measured automatically and displayed clearly 其测量法年夫优于传统的手工方法:该装置是一种低成本,高精度的单摆实验装置。 |
| 4. | In viewing of the disadvantages that printer ' s color characteristics can not be measured automatically and the low efficiency of the measuring method at present , 3 - ccd - based measuring technique is proposed 针对传统打印机彩色特性检测效率低、自动化程度不高等缺点,提出一种基于3 - ccd扫描仪的打印机彩色特性自动检测方法。 |
| 5. | In this way , the influence of artificial disturbing in the measurement is unavoidable and the result is not very accurate and can not be measured automatically and directly , furthermore , there are some unsafe elements for the use of gun powder which is used to generate a high - power acoustic signal 传统方法中,由于人为因素的影响,测量结果的误差较大,而且不直接,不方便,无法自动完成测量,同时,爆炸声源的使用引入了火工品,存在一定的安全隐患。 |
| 6. | So it is very important to study the method and technology by dual frequency laser interferometer without orbit . and it is a significative task to study a kind of instrument to measure automatically without orbit . this paper adopts a measurement project to track the measurement reflector mirror without orbit by theoretical analyzing and simulant experiment 本文通过理论分析和模拟实验,确定采用一种外置光路激光跟踪测量的方法,即:在双频激光干涉仪前面,设置一个两维跟踪反射镜,当测量反射镜移动时,测控系统驱动控制两维跟踪反射镜旋转,跟踪测量目标靶镜的运动,保证测量信号不中断,从而实现跟踪测量。 |
