Feed system uses open-loop control, stepper motor driven by the slowdown after the ball screw. driven Tool for horizontal and vertical movement; After transformation, the introduction of automatic lathe transfer Tool for automatic tool change function; To achieve automatic screw machining, in the original round of the initiative pegged to the installation of the axis of photoelectric pulse generator.

进给系统采用开环控制，由步进电机经减速后驱动滚珠丝杠，带动刀架进行横向和纵向运动；改造后的车床采用自动转位刀架实现自动换刀功能；为了实现自动螺纹切削加工，在原挂轮主动轴处安装了光电脉冲发生器。

Based on the principle of bionics and analysis of the movement mechanism of hexapod, a new type of miniature hexapod bio-robot was developed by using four-bar linkage, screw gearing, belt gear, driven by D.C. micromotor and controlled by PC.The external dimensions of the model machine are 30mm×40mm×20mm and its weight is 6.3 g.

基于仿生学原理，在分析六足昆虫运动机理的基础上，采用平面四连杆机构、蜗轮蜗杆减速机构、皮带传动机构、微型直流电机驱动和PC机控制方案，研制成一种新型&微型六足仿生机器人&，其样机外形尺寸为：长 30mm ，宽 4 0mm ，高 2 0mm ，重 6 。3g。

The switch position of butterfly disc is limited by the adjusting screw pole on the worm gear transmission device.

蝶板的开关位置都由蜗轮传动装置上的调节螺杆限位，一级传动上的行程机构同时切断电机电源，如果超过密封所需的力矩，一级传动上的力矩控制装置立即脱落，同时切断电源。

Hence all-wheel drive to deliver the power, self-shifting transmissions and, of course, traction and stability control.

因此，全轮驱动系统提供电力，自我转变传输，当然，牵引力和稳定控制。

What you get:All-wheel drive, V6 engine with 185 horsepower, four-speed automatic transmission, stability control.

有：全轮驱动，185马力的V6引擎，四速自动变速箱，稳定性控制。

It's ideal for areas of the country that experience inclimate weather conditions, as well as for drivers seeking the added handling and control benefits of all-wheel drive.

这对在全国各地的经验inclimate的理想天气条件，以及司机要添加的处理和全轮驱动控制的好处。

Otolith is calcareous concretions in fish inner earsIts composition and structure are very stableIts accretional growth follows a circadian rhythm that is physiologically controlled and influenced by environmental conditionsOtolith acts as biological archives providing the basis for the reconstruction of individual life traits and environmental parametersThe paper focuses on fish otolith trace elements and their isotopes, general testing methods and the prospect and problems of its application in environmental detection in recent 20 years, hoping that it could provide researchers with some thoughts and could expand its potential application in environmental science.

鱼耳石是鱼类内耳中的钙质沉积体，组成和结构非常稳定，它的生长轮受其生理控制和环境条件影响有规律地昼夜生长。耳石可作为鱼类的生物学记录者并为重建其生活特征和环境参数提供依据。文中就近20年来国内外关于鱼耳石微量元素和同位素方面的研究热点、鱼耳石元素研究中常用的测试分析方法以及其在环境监测中的应用前景和存在的问题作一整理和综述，望能为广大耳石研究者提供一些思路和揭示其在环境科学中的广阔应用前景。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
