In the working condition of the extruding die, the inwall of the die will bear very heavy non-uniform inner pressure along the height direction.

挤压是一种少无切削的先进加工工艺，在机械、仪表、电器、轻工、宇航、船舶及军工等部门都有广泛的应用[1]。

Having the specific knowledge of all kinds of cutting tools. Mastering mechanical drawing standard.

具有各种切削刀具的专业知识，掌握机械制图标准。

Optimum determination of cutting conditions is important in machining.

最佳切削用量的选择是机械加工中的一个重要方面。

In the process of ultrasonic vibration cutting, the resonant frequency of mechanical syntonic system varies in a wide range because of system's heating up and variable loads.

在超声振动切削中，由于系统的发热及加工负载的变化，机械谐振系统的谐振频率会在较大范围内发生变化。

If the ultrasonic power doesn't work at the resonant frequency of mechanical syntonic system, UVC is not able to go along continuously and stably.

若超声波电源的工作频率不能自动跟踪机械系统的谐振频率，超声振动切削就无法持续稳定地进行。

Yixing City Chemical Plant was built in the southeast in 1991, the main products Triethanolamine, NP series emulsifier, polyethylene glycol series; Yixingoil additive Limited was founded in 1992, the main products purificant 6501, anti-rust oil Series, 13 # machine oil, cutting fluid such as water;§Yixing railway was built in 1993, the National Ministry of Railways are fixed-point production enterprise, the main products of the three generations of railway locomotive and its combination of oil, the product responsible for the supply in eastern China oil unit of the railway locomotive.

宜兴市东南化工厂建于1991年，主要产品为三乙醇胺， NP乳化剂系列，聚乙二醇系列；宜兴海达特油添加剂有限公司建于1992年，主要产品为6501净化剂，防锈油系列，13＃机械油，水剂切削液等；宜兴市铁路油脂厂建于1993年，是国家铁道部定点生产企业，主要产品为铁路内燃机车三代油及其复合剂，产品负责供应华东地区的各铁路机车用油单位。

Unceasingly enhances along withthe modernization machine-finishing request, the people more and moremany uses compound cutting tool substitutes for the former multi-steps processing, in order to enhance the processing efficiency,clamps to the complex components processing request in an attirecarries on the multi- working procedures the centralism processing,and gradually desalinates traditional the mill, drills, thearticulation, expands and so on the different cutting craft theboundary, is the current enhancement processing efficiency mostlimited way.

随着现代化机械加工的要求不断提高，人们越来越多的采用复合刀具来取代以往的多步骤加工，为了提高加工效率，对复杂零件的加工要求在一次装夹中进行多工序的集中加工，并逐渐淡化传统的铣、钻、铰、扩等不同切削工艺的界限，是当前提高加工效率的最有限途径。

Therefor, those films can be used as hard-coating thin films to expand lifetimes of mechanical compound such as cutting tools and dies. For decorative purpers, TiN and ZrN are also employed in some case. In electronic industry, those films are used as diffusion barrier layers between Cu and Si.

这类薄膜既可作为一种耐磨及硬质薄膜而广泛用于各种切削工具、机械零部件，也可作为各种装饰薄膜应用于装饰行业，还可作为Cu 和Si 之间的扩散阻挡层。

Our main products are high-speed tool steel drill head, milling cutter, Taps, and other industrial cutting tools, annual production value of about 50 million U.S.

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
