为了尽度减多囚车削变不败的轴颈板滞强度贬矮，车削时以不兵磨损不服表背车平为佳，但还要思考到配镶钢套的壁厚强度。

This feature more than pays for itself in installation hardware and labor savings.· The system is UPS shippable and includes a 2000 or 3000 watt inverter with charger, automatic transfer switch, batteries and all controls in an unobtrusive powder-coated steel cabinet complete with adjustable wall mounting flanges.· a corded power feed and integral receptacles is also available.

在安装硬件和节约劳动力上优势更大·系统是可装运的UPS，包括2000或3000瓦的变极器，充电器，自动切换开关，电池，不引人注目的钢材质的柜子所有控件和可调节的支持墙壁的法兰·核心电源反馈和可利用的成套容器

Anneal means make harden steel soft and remove brittleness.

退火就是使淬火钢变软并消除其脆性。不适合

Once finished, most teams leave the steel tubes unpainted, in stark contrast to most types of race vehicles.

一经完成的，大多数的队让钢的管被不画，在变硬了的差别中到大多数类型的比赛车辆。

The results show that the reduction of free height of steel 44Si2CrV spring under compressive stress 900 MPa consists of two parts: plastic deformation of surface decarburized zone to hinder elastically deformed internal material recovering, making up 84% of total reduction of free height and creep of steel at ambient temperature makin...

结果表明，44Si2CrV钢弹簧在900 MPa的应力下压缩72 h，自由高度的缩短由两部分组成：表面脱碳层的塑性变形，造成对内部材料的牵制而使部分弹性变形不能恢复，由此所造成的弹簧自由高度缩短占总变形量的84％；钢的室温蠕变，占自由高度缩短的16％。

The carrying idler used on belt machine hanging in the steel wire rope, must fix with simple arch on the steel cable, which is helped for maintaining the grooved angle to be invariable and the base basically in the identical horizontal middle line.

用于挂在钢丝绳带机上的柔性托滚，需与简易弓形架配套固定在钢绳上，利于保持托滚槽形角不变和托滚底部基本在同一水平中心线上。

Products involving rough, drawing, extubation reduced strokes, straight rod, special-shaped, natural diamond, polycrystalline mode, as well as bicycles, sewing machines dedicated mold standard parts, odd-shaped molds for various species, is strong in technology have advanced equipment to improve its service life detection is 30 times more than high-speed steel, non-disposable, can be used many times to repair, rehabilitate unchanged after life.
