砂轮

An advanced intelligent system about automatic balance of on line emery cutter is introduced.

介绍了作者研制的一种新型智能化砂轮在线自动平衡系统。

A set of formula of conical surface double enveloping worm gearing had been derived and its figures,posi- tion and distribution had been depicted by graphs.

推导了锥面二次包络圆柱蜗杆传动过程中的啮合方程和主要啮合性能指标方程，以图表表示出在不同参数下其接触线、啮合界限线、根切界限线的分布图，对此种蜗杆副在砂轮的不同半径下的啮合特性进行了比较，为这类蜗杆传动中蜗轮滚刀的设计制造提供了理论基础。

I got on Board the Ship, as before, and prepar'd a second Raft, and having had Experience of the first, I neither made this so unwieldy, nor loaded it so hard, but yet I brought away several Things very useful to me; as first, in the Carpenter's Stores I found two or three Bags full of Nails and Spikes, a great Skrew-Jack, a Dozen or two of Hatchets, and above all, that most useful Thing call'd a Grindstone; all these I secur'd together, with several Things belonging to the Gunner, particularly two or three Iron Crows, and two Barrels of Musquet Bullets, seven Musquets, and another fowling Piece, with some small Quantity of Powder more; a large Bag full of small Shot, and a great Roll of Sheet Lead: But this last was so heavy, I could not hoise it up to get it over the Ship's Side.

我像前次那样上了船，并又做了一个木排。有了上次的经验，我不再把木排做得像第一个那么笨重了，也不再装那么多货物了，但还是运回了许多有用的东西。首先，我在木匠舱房里找到了三袋钉子和螺丝钉，一把大钳子，二十来把小斧，尤其有用的是一个磨刀砂轮。我把这些东西都安放在一起，再拿了一些炮手用的物品，特别是两三只起货用的铁钩，两桶枪弹，七支短枪、一支鸟枪，还有一小堆火药，一大袋小子弹，还有一大卷铅皮。可铅皮太重，我无法把它从船上吊到木排上。

Analysis was also made on the influence upon the grinding forces in case of the same friction factor between wheel and workpiece at different grinding speed, as well as in case of different friction factor between wheel and workpiece at the same grinding speed.

分析了砂轮与工件表面之间的摩擦系数相同而磨削速度不同时对磨削力产生的影响，以及磨削速度相同而摩擦系数不同时对磨削力产生的影响。

The CNC grinding wheel-dressing system is the key technique to improve the quality of gear cutter profile modification.

CNC砂轮修形系统是提高齿轮刀具修形质量的关键技术，对其进行系统与深入的研究，。。。

However,it is always a technical problem how to dress the grinding wheel.

但是砂轮的成形修整问题一直是生产过程中研究探讨的技术问题之一。

When you're using on the blades and grinding wheel.

在使用时对刀片和砂轮的影响极大。

The results prove that this method is convenient and effective, and provide a base for automatic measurement of grinding wheel.

结果表明，该方法简单有效，为砂轮自动化检测提供了一条新的思路。

Because of the width of each cutting surface I would need to dress up my grinding wheel first.

由于宽度，每个切削表面，我需要打扮我的砂轮第一。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
