Different from the routine trapeziform curve of frequency converting speed system, the motor's speed was adjusted according to exponential curve , and soft braking was realized by detent unit contained in the power module, enhancing the fluency and stability when running.

自动门的运行速度曲线与常用的梯形变频调速曲线不同，采用S形曲线对电机进行调速控制，以及采用自带缓冲制动单元的功率模块实现柔性制动，增强了自动门运行的稳定性和平滑性。

Adhesive provides books and periodicals for one-time cut, formerly of the old process, which trapeziform process generates the page negligently caused by the fault of individual books, have significant quality story.

胶黏订书刊因为一次成型裁切，减少了以前老工艺中的查梯形工序，这就会产生因加页人员疏忽而产生的个别书籍的错帖，造成重大质量故事。

The finished product in per cent, the innermost pages of the book will be around 2 mm-trim, the page quality impact too obvious, but when posts to 4 in a manner worthy of books and periodicals, back-office will normally be the accumulation of width to 3 ~ 5 mm, and innermost invisible folded edge is for form at trapeziform.

在裁成成品时，最里面的书页就会被裁去2mm左右，这对页面质量产生的影响还不算太明显，可当帖数增至4帖时，书刊的书脊处积累宽度一般会增至3～5mm，最里帖无形地被挤出，裁口处就形成梯形边。

Corolla light blue-purple; tube almost as long as calyx; throat appendages low trapeziform; lobes of limb unequal, obovate. Anthers ca.

花冠光蓝紫色；几乎的筒部倍于花萼；喉附属物低的梯形；瓣片的裂片不等长，倒卵形。

Theoretical analysis: Deduce the corresponding preliminary theoretical formula and bring forward design method of trapeziform labyrinth screw pump, Integrate professional knowledge of Fluid Machinery, Make out structure chart、 accessory charts、 experimental equipment.

理论分析：在文献基础上推导出相应的理论计算公式并初步提出梯形迷宫螺旋泵设计方法；结合流体机械专业知识，设计出迷宫泵的总体结构图、生产零件图、实验装置图。

The article introduces some needed resolving problems. It brings forward principium of control, How can drive the servo signal and X and Z to the coordination of movements; How to change the feed rate; design of system structure, confirmation for input and output point, I / O address allocation;and also the project for speedup/down control during the screwthread processing. Method of programming design and manual operation trapeziform figure in system of numerical control lathe Corresponding project to problems is provided synchronously.

Three-dimensional stress analysis was carried out for screws with four different radii and cross-sections of the taper screw including rectangle sections without, with single and double round angle transition for strengthening, and trapeziform section.

在此基础上应用ANSYS软件对无圆角、单圆角、双圆角矩形和梯形四种截面的螺杆进行了三维应力分析。

By this solid-contacting configuration, it was found that the spectra of dielectric function measured at the metal-substrate interface do change with the refractive index and differ from those measured at the metal-air interface in both the Drude and interband transition regions.

采用不同折射率的梯形棱镜作衬底，室温下用热蒸发或电子束蒸发的方法，在棱镜底面生长一系列金膜和银膜，使用椭圆偏振光谱方法分别测量了金属与空气界面及金属与衬底界面的介电函数谱。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
