He sharpened the scythes on the grindstone, slaughtered a pig, caught and salted fish, ground barley in a water-driven gristmill and grew and stored potatoes.

他用砂轮磨镰刀，宰猪，抓鱼腌鱼，在水磨坊碾大麦，种土豆收土豆。

The height distribution of abrasive grits is gained by using the data of 3-D topography.

并根据所得到的三维地貌数据，对砂轮磨刃高度分布进行了计算。

I just happened to have an old hand drill grinding wheel measuring just over 2 in diameter. I used it to even the inside hole before cutting the shroud outline on the band saw.

我刚才发生的事情有一个老手，演练砂轮测量刚刚超过2 ，直径，我用它来，甚至内孔割前徒手纲要对带锯。

It is concluded that valid grit protrusion height, mean grit edge angle and grit protrusion homomorphy can be regarded as evaluation parameters of grit protrusion behavior of diamond grinding wheel.

有效磨粒出刃高度、平均磨粒出刃角和磨粒出刃同形度可以作为金刚石砂轮修锐后的磨粒微观出刃形貌的评价参数。

We also supply various of ceramic, resin and rubber bonded wheels, centerless wheels, rubber idler pulley, resin two-side grinding wheels.

各种规格、尺寸、形状的陶瓷、树脂、橡胶结合剂的平行、无心磨轮、橡胶导轮、树脂双端面磨砂轮。

The method to develop high precision and durable idler wheel to dress the single roll wheel is expounded.

提出了开发高精度、高耐用度修整单滚道砂轮用滚轮的方法，在实验的基础上得出了可行性结论。

A precision solution of the moment of inertia of a lead screw's crosssection was obtained by interpolation polynomial and numerical integral method.

在精密长丝杠的磨削过程中，由磨削力、磨削热和砂轮磨损所引起的被加工丝杠的螺距误差已不可忽略。

Invar 36 is a kind of low expansion alloy, and it is difficult to machine because of its plastic, ductility and low heat conductivity. During Grinding, the part surface is easy to burn and wound for high grinding temperature and wheel adhesion.

Invar 36是一种低膨胀合金，其塑性大、韧性高、热导率低，磨削时所产生的磨削力大，磨削温度高，工件表面易于烧伤和划伤，对砂轮的粘附较严重，属于典型的难于加工材料。

But when I had wrought outsome boards as above, I made large shelves, of the breadth of afoot and a half, one over another all along one side of my cave, tolay all my tools, nails and ironwork on; and, in a word, toseparate everything at large into their places, that I might comeeasily at them.

我有三把大斧和许多小斧（我们带了许多小斧，是准备与非洲土人做交易用的），但由于经常用来砍削多节的硬木头，弄得都是缺口，一点也不快了。磨刀砂轮倒是有一个，但我却无法转动磨轮来磨工具。

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。
