如何利用手机翻译软件快速完成英文翻译在线?以前我们总会觉得只要我日后不出国,那么就用不到英语,可是没想到如今可能买个菜都会遇到几个外国人。那么我们该怎样与外国人交流呢?今天小编就来分享一个方法,帮助你和外国人无阻碍交流。

1:打开我们的翻译工具后,首先选择好翻译模式,总共有语音翻译和文本翻译两种翻译模式,小编通常选择语音翻译模式来与外国人交流。

2:选择语种,源语种选择中文或者是中文简体,目标语种选择英文,当然不知道对方是哪国人,你也可以先用英语打个招呼。

3:开始进行语音翻译,点击最下角的中文按钮,将手机靠近嘴部开始说话,录音结束后点击完成按钮,进入翻译结果页面。

4:翻译结果会以语音播放和文字框两种方式同时呈现,并且在文本框中还有一个喇叭状按钮,点击按钮可以对语音进行重复播放。

5:在我们的翻译软件“语音翻译器”中,还可以进行中英文相互翻译。点击最下角的英文按钮,说出英语,点击完成按钮开始进行英语对中文的翻译。

6:语速调节,点击设置按钮,里面有一个语速调节,如果你语音播放的语速过快或者过慢都会引起沟通上的不便,所以我们要适当的调节语速。

7:文本上传,点击文本框会有许多的编辑方式,点击上传你可以通过手机中的社交工具,上传和分享你的文本。

8:意见反馈,设置按钮中另一个主要功能是意见反馈,点击意见反馈按钮,你可以通过电话或者邮箱的形式反馈你的问题,寻求解决的方法。

以上就是小编分享的关于如何利用手机翻译软件快速完成英文翻译在线的方法,如果你身边也有外国朋友,那么不妨尝试一下小编的方法。如果能帮助到你,小编也非常高兴。

建筑结构在冲击负载作用下连续倒塌分析方法 摘要:建筑物在冲击负载作用下的连续倒塌已经引起了全世界的极大关注。对于一个经济的,安全的,能够抵抗冲击负载作用下连续倒塌的建筑结构设计,连续倒塌分析是必不可少的。因为连续倒塌的灾难性特点,和为了抵抗它而潜在的建造和改造建筑物的高额费用,所以连续倒塌分析方法是绝对必要且可信的。对于工程师们而言,他们估算连续倒塌的方法不仅仅要求精确和简要,而且容易上手,立竿见影。因而,最近许多研究者都在发展可靠有效和直接的连续倒塌分析方法上花费了很多的精力。在最近的干物上,当前在文献资料中找得到的关于连续倒塌的分析方法被重新审阅。人们广泛讨论它们的适宜性、适用性和可靠性。我们也提出了最近刚刚完成的关于钢筋混凝土框架在爆破荷载下的连续倒塌新分析方法。 关键词:连续倒塌分析;建筑结构;爆炸荷载;冲击荷载 连续倒塌被定义为“由于一个基本的局部构件失效在构件之间扩散最终造成整个结构或者是不成比例的一大部分倒塌”。其含义为一个或者一组关键承重构件的失效造成周围构件的失效和部分或者是整个结构的倒塌。建筑结构的连续倒塌可能由一系列的意外和人为的因素造成,比如:错误的建造顺序,偶然过载造成的局部失效,爆炸和地震造成的关键组件的损坏。这篇论文仅仅研究了特殊荷载(如:爆炸和冲击),造成的建筑结构连续倒塌的分析。 随着最近Alfred P.Murrah联邦大楼和世界贸易中心(WTC)的倒塌,许多的研究更多的关注如何建造抵抗由于爆炸和冲击荷载造成连续倒塌的建筑。对于一个经济的,安全的,能够抵抗冲击负载作用下连续倒塌的建筑结构设计,连续倒塌分析是必不可少的。因为连续倒塌的灾难性特点,和为了抵抗它而潜在的建造和改造建筑物的高额费用,所以连续倒塌分析方法是绝对必要且可信的。对于工程师们而言,他们估算连续倒塌的方法不仅仅要求精确和简要,而且容易上手,立竿见影。因而,最近许多研究者都在发展可靠有效和直接的连续倒塌分析方法上花费了很多的精力。

The machine design is a creative work. Project engineer not only must have the creativity in the work, but also must in aspect and so on mechanical drawing, kinematics, engineerig material, materials mechanics and machine manufacture technology has the deep elementary knowledge. 任何产品在设计时第一步就是选择产品每个部分的构成材料。许多的材料被今天的设计师所使用。对产品的功能,它的外观、材料的成本、制造的成本作出必要的选择是十分重要的。对材料的特性必须事先作出仔细的评估。 One of the first steps in the design of any product is to select the material from which each part is to be made. Numerous materials are available to today's designers. The function of the product, its appearance, the cost of the material, and the cost of fabrication are important in making a selection. A careful evaluation of the properties of a. material must be made prior to any calculations. 仔细精确的计算是必要的,以确保设计的有效性。在任何失败的情况下,最好知道在最初设计中有有缺陷的部件。计算(图纸尺寸)检查是非常重要的。一个小数点的位置放错,就可以导致一个本可以完成的项目失败。设计工作的各个方面都应该检查和复查。 Careful calculations are necessary to ensure the validity of a design. In case of any part failures, it is desirable to know what was done in originally designing the defective components. The checking of calculations (and drawing dimensions) is of utmost importance. The misplacement of one decimal point can ruin an otherwise acceptable project. All aspects of design work should be checked and rechecked. 计算机是一种工具,它能够帮助机械设计师减轻繁琐的计算,并对现有数据提供进一步的分析。互动系统基于计算机的能力,已经使计算机辅助设计(CAD)和计算机辅助制造(CAM)成为了可能。心理学家经常谈论如何使人们适应他们所操作的机器。设计人员的基本职责是努力使机器来适应人们。这并不是一项容易的工作,因为实际上并不存在着一个对所有人来说都是最优的操作范围和操作

外文翻译 英文原文 Belt Conveying Systems Development of driving system Among the methods of material conveying employed,belt conveyors play a very important part in the reliable carrying of material over long distances at competitive cost.Conveyor systems have become larger and more complex and drive systems have also been going through a process of evolution and will continue to do so.Nowadays,bigger belts require more power and have brought the need for larger individual drives as well as multiple drives such as 3 drives of 750 kW for one belt(this is the case for the conveyor drives in Chengzhuang Mine).The ability to control drive acceleration torque is critical to belt conveyors’ performance.An efficient drive system should be able to provide smooth,soft starts while maintaining belt tensions within the specified safe limits.For load sharing on multiple drives.torque and speed control are also important consideratio ns in the drive system’s design. Due to the advances in conveyor drive control technology,at present many more reliable.Cost-effective and performance-driven conveyor drive systems cov ering a wide range of power are available for customers’ choices[1]. 1 Analysis on conveyor drive technologies 1.1 Direct drives Full-voltage starters.With a full-voltage starter design,the conveyor head shaft is direct-coupled to the motor through the gear drive.Direct full-voltage starters are adequate for relatively low-power, simple-profile conveyors.With direct fu11-voltage starters.no control is provided for various conveyor loads and.depending on the ratio between fu11- and no-1oad power requirements,empty starting times can be three or four times faster than full load.The maintenance-free starting system is simple,low-cost and very reliable.However, they cannot control starting torque and maximum stall torque;therefore.they are

另外,在翻译过程中最好以“段落”或者“长句”作为翻译的基本单位,这样才不会造成“只见树木,不见森林”的误导。 注: 1、Google翻译:https://www.sodocs.net/doc/9e4467627.html,/language_tools google,众所周知,谷歌里面的英文文献和资料还算是比较详实的。我利用它是这样的。一方面可以用它查询英文论文,当然这方面的帖子很多,大家可以搜索,在此不赘述。回到我自己说的翻译上来。下面给大家举个例子来说明如何用吧 比如说“电磁感应透明效应”这个词汇你不知道他怎么翻译, 首先你可以在CNKI里查中文的,根据它们的关键词中英文对照来做,一般比较准确。 在此主要是说在google里怎么知道这个翻译意思。大家应该都有词典吧,按中国人的办法,把一个一个词分着查出来,敲到google里,你的这种翻译一般不太准,当然你需要验证是否准确了,这下看着吧,把你的那支离破碎的翻译在google里搜索,你能看到许多相关的文献或资料,大家都不是笨蛋,看看,也就能找到最精确的翻译了,纯西式的!我就是这么用的。 2、CNKI翻译:https://www.sodocs.net/doc/9e4467627.html, CNKI翻译助手,这个网站不需要介绍太多,可能有些人也知道的。主要说说它的有点,你进去看看就能发现:搜索的肯定是专业词汇,而且它翻译结果下面有文章与之对应(因为它是CNKI检索提供的,它的翻译是从文献里抽出来的),很实用的一个网站。估计别的写文章的人不是傻子吧,它们的东西我们可以直接

英语原文 NUMERICAL CONTROL Numerical control(N/C)is a form of programmable automation in which the processing equipment is controlled by means of numbers, letters, and other symbols, The numbers, letters, and symbols are coded in an appropriate format to define a program of instructions for a particular work part or job. When the job changes, the program of instructions is changed. The capability to change the program is what makes N/C suitable for low-and medium-volume production. It is much easier to write programs than to make major alterations of the processing equipment. There are two basic types of numerically controlled machine tools:point—to—point and continuous—path(also called contouring).Point—to—point machines use unsynchronized motors, with the result that the position of the machining head Can be assured only upon completion of a movement, or while only one motor is running. Machines of this type are principally used for straight—line cuts or for drilling or boring. The N/C system consists of the following components:data input, the tape reader with the control unit, feedback devices, and the metal—cutting machine tool or other type of N/C equipment. Data input, also called “man—to—control link”,may be provided to the machine tool manually, or entirely by automatic means. Manual methods when used as the sole source of input data are restricted to a relatively small number of inputs. Examples of manually operated devices are keyboard dials, pushbuttons, switches, or thumbwheel selectors. These are located on a console near the machine. Dials ale analog devices usually connected to a syn-chro-type resolver or potentiometer. In most cases, pushbuttons, switches, and other similar types of selectors are digital input devices. Manual input requires that the operator set the controls for each operation. It is a slow and tedious process and is seldom justified except in elementary machining applications or in special cases. In practically all cases, information is automatically supplied to the control unit and the machine tool by cards, punched tapes, or by magnetic tape. Eight—channel punched paper tape is the most commonly used form of data input for conventional N/C systems. The coded instructions on the tape consist of sections of punched holes called blocks. Each block represents a machine function, a machining operation, or a combination of the two. The entire N/C program on a tape is made up of an accumulation of these successive data blocks. Programs resulting in long tapes all wound on reels like motion-picture film. Programs on relatively short tapes may be continuously repeated by joining the two ends of the tape to form a loop. Once installed, the tape is used again and again without further handling. In this case, the operator simply loads and
