正交圆 [zhèng jiāo yuán]
orthocycle
- 摘要本文作者设计了新型四联动平面二次包络蜗杆数控磨床的数控及电控系统，该磨床采用虚拟中心的方法，通过两正交轴的圆插补及磨头基座的自转实现了传统蜗杆加工磨床上的砂轮工作面的平面回转运动，克服了传统加工蜗杆工作层面多，结构复杂，加工精度、效率低等缺点。
This paper analyzes and discusses the problems involving the design of the electronic control (EC) and numerical control (NC) systems for a new type NC grinder-machine used to grind planar quadratic and annular enveloping worms based on novel four-axis-interpolation, in which a central fabricating method is introduced. - 样本被架在特殊的支架上，支架被放置在目标透镜的圆孔中，使得标本倾斜的角度能够超过30穿过两个正交的角，然后适用的晶体学分析再展开。
The specimen is mounted in a special holder which fits into the bore of the objective lens and enables the specimen to be tilted through angles greater than 30 about two orthogonal axes so that appropriate crystallographic analyses can be carried out. - 方法选用L9(3^4)正交试验，以水提次数、醇沉体积分数、盐溶的氯化钠质量浓度为因素进行比较，对影响圆背角无齿蚌中有效组分的提取工艺进行优选。
Methods L9 (3^4) Orthogonal test was used with three factors, including times of water extracting, concentration of ethanol precipitation, and concentration of sodium chloride.
