指令

Through reforming the YC7150 gear grinding machine of conical surface of grinding wheel by CNC,the proposed approach will be of much help in increasing the accuracy of the grinding machine tools and can also be used to change the equipment of gear process,and can give rise to the principle dividing precision less one pulse equivalent .

对高精度齿轮加工设备的传动原理进行了分析，具体研究了在高精度数控分度时计算分度指令脉冲数所采用的均匀分配脉冲数的方法，并用此算法对 YC715 0锥面砂轮磨齿机进行数控改造，以进一步改善齿轮加工设备，提高机床加工精度，使理论分齿精度小于一个脉冲当量。

This directive specifies the DN that is not subject to access control or administrative limit restrictions for operations on this database.

本指令指定的 DN 对本数据库的操作不受访问控制或管理权限的限制。

Control unit :tells the rest of the computer system how to carry out a program's instructions .

控制单元：告诉其余的计算机系统如何执行程序的指令。

Command economy: An economy whereactivity is controlled by the government ratherthan being left to private enterprise and themarket forces of supply and demand.

指令经济：由政府控制经济活动，而不是由私营企业和市场供求力量的作用自行调控的一种经济形式。

Command economy; controlled economy; directed economy An economy in which a significant amount of end results is due to the deliberate decision of government bodies rather than to consumer choice plus forces of supply and demand.

管制经济；控制经济；指令经济指一国经济中相当大部分的最终产品的生产是由政府机构的主观决策决定的，而不是来自消费者的抉择和供求的力量。

The interface also provides a spatial positioning method which helps designers to eliminate the commands of converting a coordinate axis.

并且提供一套空间定位的座标系统让设计者不需透过转换座标轴指令的步骤达成CAD环境中的空间操作。

A computer is controlled by a stored program: thus, the first step in using the machine is to copy the program from diskette into memory Now, the processor can begin executing instructions.

计算机是由存储器程序来控制的；这样，使用机器的第一步，就是将程序从软盘复制到存储器中去。现在，处理器能够开始执行指令了。

Obviously I did not copy the correct file so could you please give me more instructions.

很显然，我并没有复制正确的文件，因此，请你给我更多的指令。

EXAMPLE: We received an urgent countermand from the client today that reversed the instructions we received from them yesterday.

我们今天收到了客户紧急止付单，撤消了我们昨天收到的指令。

They were also able to prevail on the president, who was appointed to the supposedly ceremonial role by parliament, to countermand the cabinet's order to sack General.

如那样，他们也能说服那个由国民大会任命的形式上的总统撤销内阁关于解除Katawal将军职务的指令。

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。
