As if that wasn't bad enough, Microsoft performs cursor hinting using the detestable circle with a bar sinister, the universal icon for Not Permitted.

这好像还不是最坏的，微软还用讨厌的带斜杠的圆形进行光标暗示，通常这个图标表示&禁止&。

That still in the barrel, creating process variables that may influencethe next shot.

回退的料的温度和压力可能与仍在丝杠内的不同，造成工艺参数的变化从而影响下一次的注射。

The returning material may be of a temperature or pressure different than that still in the barrel, creating process variables that may influence the next shot.

回退的料的温度和压力可能与仍在丝杠内的不同，造成工艺参数的变化从而影响下一次的注射。

The design work involves: overall design of milling machine, draw out of drive project, design of lathe bed, theory design and calculate of feed part, and the design of to-and-fro guide screw leading screw for profile modeling machining.

专用铣床的设计包括：铣床的总体设计，传动方案的拟订，床身的设计，进给部分的理论设计和计算，以及用来仿行加工的往复丝杠的设计。

BG type offers a unique " U " shaped guide rail and slide block which provides multiple functions of a guide block and a ball screw nut combined into a single unit.

BG系列模组是一个独特的& U &形传动导轨和滑块提供多种功能固定座和滚珠丝杠螺母合并成一个单一的单位。

Combination machine tools of future development will be more adopts stepless motor and transmission of ball screw, etc, to simplify structure and shorten the production beat, Using digital control system and spindle box, jig automatic replacement system, in order to improve the process adjustability, Flexible manufacturing systems and into.

组合机床未来的发展将更多的采用调速电动机和滚珠丝杠等传动，以简化结构、缩短生产节拍；采用数字控制系统和主轴箱、夹具自动更换系统，以提高工艺可调性；以及纳入柔性制造系统等。

Main camp product :The ball bearing guide screw (may completely according to chart processing, welcome to attempt inquired), the straight line optical axis is by the technology which accumulates in the axis outer diameter common difference, the straight dimension, circumference, in the surface roughness guarantees the very high accuracy.

主营产品：滚珠丝杠（可完全按图加工，欢迎来图询问）、直线光轴是以积累的技术在轴的外径公差，直线度，圆周度，表面粗糙度上保证很高的精密度。

When a motor rotates, a ball feed screw pair converses positive and reverse rotation into advance and recession of the cap nut, thus the rotation directions of the motor can be directly and clearly identified.

电机转动时，滚珠丝杠副将正、反向旋转运动转化为螺母的前进和后退，故可快速直观地判断电机高速运行时的转动方向。

An overhanging part, the apron of the carriage, may be engaged with the feed rod to give continuous feed motion, or with a lead screw for cutting of threads.

一个伸出的部分，支架的围裙，也许以饲料标尺给连续的合闸动作，或者与螺纹切口的丝杠衔接。

She gently rebuff ed him, but agreed that they could be friends
