然后

The sunken by corrosion to black oil quality, and then wash away the acidproof film, which is transparent and opaque glass line version sattle.

不纬腐化瘪下的局部涂上白色油质，然后洗去耐酸膜层，这样不离制不败了透明与不透明相间的玻璃线条版。

Then the platform—ACIS for the development of verification system, including its development interface, data structure, main functions, features and the application in the system is introduced.

然后platform-ACIS检定系统的发展，包括其发展的人机界面、数据结构、主要功能、特点和应用系统的介绍。

First, the definition, significance, research emphases and status of NC machining verification technology are introduced in this paper. Then the platform—ACIS for the development of verification system, including its development interface, data structure, main functions, features and the application in the system is introduced. And, we indicate in brief the correlative knowledge of NC machining and then discuss the definition of the machining environment of NC machining verification system as well as the way that the module has been developed. Finally, we describe how to make Help Files and the structure of the Help Files in the system.

本文首先对数控加工动态仿真技术的定义、意义、研究重点、研究状况进行了介绍；并介绍了可用于开发数控仿真系统的实体造型平台—— ACIS ，包括 ACIS 的开发接口、数据结构、主要功能与特色以及在数控仿真系统开发中的应用；然后通过简要介绍数控加工的一些相关知识，引出了数控仿真系统加工环境的定义与该模块的实现方法；最后讲述了帮助文件的制作以及该系统帮助文件的结构。

Then when it comes to English study, why do you ack like a duck?

然后，当谈到英语学习，你为什么像鸭子又来了？

It's an undeniable urge to rake leaves, start planning for Halloween, cook up a nice acorn squash (seasoned with butter and a bit of garlic), and brew a pot of Assam tea to go with it.

这是一个不可否认的强烈欲望，去耙叶，为万圣节开始规划，做了一个不错的橡树果泥球，然后沏一壶 Assam的茶。

You dialed the computer's number and then placed the hand set into the acoustic coupler and you were ready to go.

你拨打电脑的号码，然后放入声学耦合器设置手，你准备去。

To work the acoustic coupler, start the computer's communications program, dial the distant computer on a single line telephone with a normal e.g.

使用声音耦合器时，首先启动计算机通信程序，然后再拨打远端计算机。

An analytic expression for the acoustic pressure in farfield are then obtained.

考虑弹性结构、可压缩流体和粘弹性消声瓦在交界面上的相互作用，然后给出了远场声压的解析表达式。

It then combines this information to provide an accurate representation of the room's acoustical problems.

然后，结合此信息来提供准确的代表房间的声学问题。
