导螺杆英文

单螺杆设备螺杆与料筒的间隙在0.2mm时是能耗最低的。螺杆（拼音：luógǎn，英文：screw）：外表面切有螺旋槽的圆柱或者切有锥面螺旋槽的圆锥。螺杆具有不同的头，像图片中的头叫外六角螺杆。还有其他，例如大扁螺杆、内六角螺丝等等。由挤出过程可知，螺杆是在高温、一定腐蚀、强烈磨损、大扭矩下工作的，因此，螺杆必须：螺杆1）耐高温，高温下不变形；2）耐磨损，寿命长；3）耐腐蚀，物料具有腐蚀性；4）高强度，可承受大扭矩，高转速；5）具有良好的切削加工性能；6）热处理后残余应力小，热变形小等。

学习中，了解一点机械类的知识有意义！

重点的英文：emphasis；key point

key 读法 英 [kiː]

1、n. （打字机等的）键；关键；钥匙

2、vt. 键入；锁上；调节…的音调；提供线索

3、vi. 使用钥匙

4、adj. 关键的

短语：

1、key factor 关键因素；主要因素

2、key in [计]键入

3、on key 上机

4、key issue 关键议题

5、key link 关键环节；中心环节

一、key的词义辨析：

key的后置定语可由of引起,也可由to引起,其区别是：

1、作“钥匙”解时, of后接“房间,建筑物”等, to后接“门,锁”等

2、作“关键”解时, of后接一般事物, to后接“成功”等结果名词

3、作“…的键”解时,用of,作“通往…的要冲”“…的答案”解时,用to。总之,含有方向、结果等意味时接to,表示所属时用of。

二、key的近义词：lead

lead 读法 英 [li:d;led]  美 [lid; lɛd]

1、n. 领导；铅；导线；榜样

2、vt. 领导；致使；引导；指挥

3、vi. 领导；导致；用水砣测深

4、adj. 带头的；最重要的

短语：

1、lead paint 铅涂料；铅丹

2、lead free adj. 无铅的

3、lead screw 导螺杆

4、lead content 含铅量

5、lead up 引入；抢先

应该说丝杆是螺杆的一种，丝杆一般是指螺距比较小的，一般说的螺杆的导程或者螺距比较大些。
