1) lengthening
[英]['leŋθən] [美]['lɛŋθən]
加长
1.
The lengthening project increases the dock net lift capacity from 36 000 t to 43 000 t and extends the dock block supporting length from 235 m to 287 m,in order to enable the dock ships with its overall length of 305 m.
香港友联船厂在其"友联叁号"浮坞前端连接了一个与原坞同宽,长51 m的加长分段,将该坞净举力从36 000 t提高到了43 000 t,浮箱长度从原来的235 m增加到287 m,使之可以起浮长达305 m的巨型集装箱班轮。
2.
This paper mainly discusses the lengthening alteration of beaching wedged chassis originally designed for slipping of caissons for repairing large engineering ships.
主要讨论把原设计用于沉箱溜放的斜架车加长改造,用于大型工程船舶拉排修理。
2) shoot elongation
加长生长
1.
Adding gibberellic acid(GA 3) and reducing the NH 4NO 3 concentration to 1/2?MS medium promoted shoot elongation compared with sucrose.
４ ｍｇ／Ｌ；培养基中加入ＧＡ３ 和降低ＮＨ４ＮＯ３ 浓度有利于加长生长；用山梨醇作碳源时芽的增殖倍数高于蔗糖，而生根率低；２ 个品种中，“晚红李”的增殖和生长优于“美丽李”，而生根率无明显差异。
2.
Adding gibberellic acid(GA 3) and reducing NH 4NO 3 concentration of MS medium promoted shoot elongation.
培养基中加入ＧＡ３和降低ＮＨ４ＮＯ３浓度有利于加长生长。
3) Accumulated chord
累加弦长
1.
In this paper,the factors which influence the high speed and accuracy CNC machining are analyzed,and a cubic spline interpolation algorithm is presented,which takes the accumulated chord as its parameter.
该文分析了影响曲线、曲面加工精度和速度的因素,提出了一种基于累加弦长的三次参数样条曲线插补算法,并采用脉冲均匀化、速度预处理等方法,将其运用于GL-2000数控系统取得了非常好的效果。
4) cutting step
加工步长
5) lengthened reamer
加长铰刀
6) lengthening spindle
加长主轴
1.
To surmount the difficulty of machining spindles with inverted taper bore, the methods such as lengthening spindle, using template, making machine tool rotate reverse, translating tool bar and so on are adopted to ensure the concentricity, taper and size accuracy of spindles with inverted taper bore.
针对带内锥主轴加工难的问题,采用加长主轴、利用样件、机床反转、刀杆平移等方法,来保证带内锥主轴和内孔的同轴度、锥度以及尺寸精度。
