Good practice in engineering drawing, must be able to consider datum position, key dimension control and tolerance stack-up.

工程制图方面有很好的操作和应用，能够考虑基准的选取和定位、关键尺寸的控制、以及设计制造公差的累积

Good practice in engineering drawing, must be able to consider datum po sition, key dimension control and tolerance stack-up.

Software, and simulated by Monte Carlo method. The simulation results are conducted by descriptive statistics. Two "drop-in" assembly design lens groups were studied to calculate the stack-up element tilt and decenter within a cell and the resultant deviations of the optical axes away from the mechanical datum axis. The results indicate that the opto-mechanical tolerance model can analyze the critical to quality parameters of a lens system. As a result, the performance of the lens system can be anticipated by the opto-mechanical tolerance model before mass production.

戊n体编辑，并以蒙地卡罗方法模拟，模拟结果以叙述统计呈现；最后以两个"投入式"组立设计的镜群组为案例，计算镜片在镜筒内的累积偏心角度公差、偏心距离公差及镜片光学轴的累计偏移量，其结果显示该模型可模拟一个镜头系统的关键品质参数；所以，镜头系统的性能在大量生产之前可藉本光机公差模拟模型预测其品质与良率。

The primary goal of this research is to improve the limit of traditional forecasting methods by using grey prediction skill that required just four datum to analyze the teacher supply and demand problem resulted from the reduce of "class size" number. The results are as follows

本文研究的主要目的即针对改善传统预测方法对所需数据个数过多的要求限制，采取灰预测技术仅需四个数据即可加以建模预测，藉以分析因为班级规模人数降低所衍生的师资供需问题。

Although the ordinary stack velocity analysis method has already matured the ordinary NMO equation is based on the supposal that the shot and receiver points are located a same horizontal datum plane .

常规叠加速度分析方法虽然业已成熟，然而常规动校正方程是基于炮，检点处于同一水平基准面的假设，在地表起伏较大的地区，即使采用浮动基准面的方法，其速度分析误差也不容忽视。

Based on the example of turbine reverse engineering , the general procedure that can be used to translate the physical object into CAD datum by Surfacer software is determined in this paper1 By going deep into the vector of point-cloud , it's parametrization can be gained by adopting the precept of accumulating chordal parametrization1 According to the principle of const ructing curve using the least square method , the high quality-curve can be gained by modifying curve's parameter1 This paper also empha2sizes on some methods about processing point-cloud , const ructing curve and const ructing surface1 And it can provide several methods to const ruct high quality2CAD model for mould machining1
