密位

本文介绍了一种应用于周视瞄准镜的光电自动测角系统，其精度可达±0.1密位。

In this paper , it is recommended an opto-electronic automatic measuring angle system which can be applied to the panoramic sight . The precision attains ± 0.1 mil .

实验结果表明，就本文实验所用陀螺，含二次项误差的模型寻北精度较高，使寻北精度从零次拟合模型的1密位降低到0.5密位。

The result shows that the third model can acquire higher precision when using the above gyro to seek north , improving from 1 mil by zero-order fitting model to 0.5 mil by second-order fitting model .

其判读系统接收CCD视频信号，经自动或半自动判读进行二维图像叠加及三维数据处理，得出10密位圈内的弹数，完成实弹射击成绩评定。

The evaluation system accepted CCD video frequency signal and read the count of the passing points in the 10-mill circle by automatism or half-automatism judgment to carry out 2-dimension image addition and 3-dimension data disposal , accordingly accomplish the evaluation of the firing results .

测地式系统的基线长度约为0.8m，定向精度优于1密位（0.06°，1σ），定向时间少于4min。

The ground-used system has a baseline about 0.8m long . The orientation can be determined by the system in less than 4 minutes with a precision better than 0.06 ° ( 1 σ) .

研究表明，这种码字可以很方便地实现由密令、密位或密标组成的多层保密系统。

It is shown that a multiple encryption system consisting of encrypted instructions , encrypted locations and encrypted labels can be implemented by such a code without difficulty .

但由于受到结构及坦克空间约束，方向机的传动比基本上均匀分配，系统各级精度均对系统误差产生影响，因而空回量大、传动精度低，通常在2.5密位以上。

Limited by the structure and space in tank , basically , the transmission ratio distributes uniformly . So each precision grade has effect on system error . The backlash is great and the transmission precision is low , usually over 2.5 mil .

结果：161颗后牙残冠、残根的铸造桩核就位顺利，边缘密合，烤瓷冠或金属冠边缘密合，固位良好。

Results : The 161 ports and cores were seated precisely , the porcelain or metal crowns margin was fitted well and the retention of crowns was good .
