The tooth contact and kinematic precision of cone-generated double-enveloping worm gearing with machining and assembling errors have been investigated.

对存在加工及装配误差的锥面二次包络环面蜗杆传动进行了接触分析，探讨了各种制造误差对齿面接触质量和运动精度的影响规律和影响程度，提出了矫正由加工误差引起的齿面接触偏倚，减小运动误差的装配调整作业法。

While U denotes an Up Face quarter turn of 90 degrees clockwise, U2 denotes a 180 degrees turn and U' denotes a quarter turn of 90 degrees counter-clockwise.

U的意思就是把'上'面顺时针旋转90度。而U2的意思是把'上'面顺时针旋转180度。U'的意思是把'上'面逆时针旋转90度。

Tang Mian flesh is meat, add flour in the amount of salt and pepper noodles, hot oil, oil temperature should be moderate, not too high and will prevent the hot flour paste, and the second step is to face a good hot rolled up into a good In the face of the quarter, rolling up flange, a circular made into a special sub-branded over the roast, no smell of fuel used for charcoal, grilled over time continue to Cayou warming, can be cooked.

肉瓤是烫面，在面粉中加入适量的花椒面和食盐，用油烫制，油温要适中，不可过高，防止将面粉烫糊，第二步是将烫好的面裹进醒好的面季中，翻边推擀，做成圆形，放入特制的烙子上翻烤，燃料用无异味的木炭为好，翻烤时不断擦油增温，熟透即可。

Two pairs of chutes and holes on the cleaning base and the brushes form the double chute swing mechanisms by the connection of an axis and cause the brush to cling to the wall surface to clean by the friction feedback, thus achieving effective cleaning when walking error occurs and the pipe section changes, furthermore, the larger the friction on the wall surface is, the larger the forward pressure on the wall surface is, therefore, the dirtier the wall surface is, the higher the cleaning efficiency is.

清扫底座与刷子夹上的两对滑槽和孔通过轴的连接形成双滑槽摆动机构，并通过摩擦力反馈使得刷子能够紧贴壁面进行清洗，从而在出现行走误差和管道截面变化时都能够有效清洗，并且壁面摩擦力越大刷子作用在壁面上的正压力越大，因此壁面越脏时清扫效率越高。

To evaluate the simulations of the four-stream model for solar radiative flux reflected by land surface in land surface model, the four-stream model and the two-stream model were coupled into land surface process model.

利用第2次雪模式比较计划SNOWMIP资料和改进的10层陆面模式BATS进行耦合试验，将四流模式以及二流模式均耦合到该陆面模式中，其目的是为考察四流模式对陆面模式模拟地表反射太阳短波辐射通量的影响。

In order to understand better the process of hydrocarbon formation and the effect of the top land crevice and the oil layer of the cylinder liner on unburned hydrocarbons during cold start and idling period,the temperature of piston top land and liner has been measured.

为了更好地弄清起动和怠速时发动机缸内未燃碳氢生成过程以及顶岸间隙和油膜对缸内未燃碳氢的影响，测量了起动和怠速过程活塞顶岸壁面和缸套壁面温度。根据测量结果，预测了起动过程顶岸间隙和壁面油膜处未燃碳氢生成量，发现顶岸和缸套壁温在发动机起动后（150～200）s时达到其稳定状态。

ABSTRACT Based on analysis of form-surface hard turning control, the concept of form-surface hard turning 5-axis simultaneous control and design scheme of turning simultaneous tool post are proposed in this paper.

本文在分析硬型面数控车削加工控制要求的基础上，首次提出了硬型面数控车削加工五坐标联动控制的概念，并提出了硬型面数控车削加工机床联动刀架的设计方案，填补了数控车削加工多坐标技术的空白。

Common rolling plank is shown intense (orientaton of 0002) tool reference plane, after rolling of horn waiting for diameter, plank grain orientaton by original (change of orientaton of 0002) tool reference plane is; of orientaton of blame tool reference plane the existence after strain crack of common rolling plank is many twin brilliant, amount of brilliant of twin of drawing of direction of rolling of edge of plank of rolling of horn w

普通轧制板材呈强烈的(0002)基面取向，等径角轧制后，板材晶粒取向由原来的(0002)基面取向转变为非基面取向；普通轧制板材拉伸断裂后存在大量孪晶，等径角轧制板材沿轧制方向拉伸孪晶数量明显减少，等径角轧制有可能启动了新的滑移系，而拉伸孪生只是作为一种协调变形机制。

The geoid is used to be regarded as the theoretic global vertical reference .The actual national height references are regional mean sea levels determined by tide gauge station. The difference between them is apparent. The satellite altimetry has developed as a kind of important space geodetic technique since 1970s.

大地水准面作为全球高程测量的理论基准面，在现实工作中，国家或者地区高程系统的起算面是利用验潮方法来确定局部平均海平面的，两者之间的差距是显而易见的。

In General, allow a printing plate over minutes and slightly smaller film locations, if printing plate dot dot scores color film, the Sun from a printing plate is too deep.

凡是环境下，不准印版比电不合胶片的网不面略小一些，如果印版的网不面比不合色胶片网不面不小些，则暗示晒不入来的印版太浅。
