运行时间

Using direct calculation method can easily change in acceleration and deceleration time, maximum start frequency, maximum operating frequency in order to adapt to different processing conditions.

采用直接计算的方式可以方便的改变加减速的时间、最高启动频率、最高运行频率以适应不同的加工状况。

This algorithm provides a more continuous feed motion using C2 continuous derivatives and nearly-arc spline parameterization.

该算法采用二阶连续可导的五次样条和近弧长样条参数提高了进给运动的连续性；速度控制算法保证机床在高速运行过程中加加速度的二次连续、加速度、速度和位移与时间关系的高阶连续变化，并且保证在各自的约束范围内，从而使机床的运动平稳，避免产生大的冲击和振动，同时有利于提高加工质量，减少加工时间。

These 2 I don't recommend that they run in the background, but from time to time, just keep the lists updated and they provide protection by immunising your system.

这些二，我不建议他们在后台运行，而是由时间来时间，只要不断更新的名单和他们提供保护，由immunising您的系统。

Machine set-up time is fast on the Xeikon presses, eliminating the long make-ready times required by traditional methods, and reducing the high fixed costs associated with conventional set-ups that make short runs unaffordable.

机设定的时间快了赛康印刷机，消除长期进行，由传统的方法需要准备时间，并减少固定费用高与常规设置相关的制成品，使短期运行负担不起。

This global network of 3 million computers averages about 14 TeraFLOPS, or 14 trillion floating point operations per second, and has garnered over 500,000 years of processing time in the past year and a half.

大约 300 万台计算机，计算效率约为平均每秒运行 14 TeraFLOPS 或 14 兆浮点操作每秒，在过去的一年半的时间里项目共计调用了大概 500，000 年的 CPU 处理时间。

The response time of different ultraviolet fire detectors was tested by the system. The results show that the design of the response time test system of fire detector is feasible and it avoids the measuring error caused by the asynchronous operation in traditional response time test method.

样机运行的测试结果表明：该响应时间测试系统的设计是成功的，消除了现行火焰探测器响应时间测试方法中存在的点火与计时不同步而引起的测量误差。

The disturbances on power system are calculated and analyzed, and the conclusions show that self excited shunt excitation system with less rise time and overshoot has good quality in majority disturbances.

所选的项目也是发电机在运行中会遇到的扰动。临界切除时间和强励上升速度用以检查对暂态稳定的影响。较长的临界切除时间和较快的强励上升速度反映较优的暂态稳定性。

On the basis of the system of signal control theory at cross roundabout, the optimization of control method based on the dissymmetry of roundabout at coordinated control system is put forward. This new method takes the equilibrium of saturation-degree as a target and optimizes the phase model and the green ratio model.

在已建立的十字环形交叉口信号控制理论的基础上，通过分析十字环形交叉口的车辆运行特征，提出基于非对称性的优化控制理论，同时建立非对称控制相位确定方法、非对称绿灯时间模型以及优化绿灯时间的计算方法。

In order to study the influence of delays in right-turn traffic,this paper analyzed the characteristic of right-turn traffic on signal control intersection,on this basis,useing the mentality that the green and the red signal times' right-turn traffic study separately,proposed three models to calculate right-turn traffic delays on signal control intersection,has laid certain foundation for the appraisal of signal control intersection's service level.

为了研究右转车流延误的影响，本文分析了信控交叉口右转车流运行特征，在此基础上，采用将绿灯信号时间和红灯信号时间的右转分别进行研究的思路，提出了计算信控交叉口右转车流延误的三种模型，为评价信控交叉口的服务水平奠定了一定的基础。

It took Cockcroft and Walton five years to build a machine that worked. Finally, in April 1932, they had a machine that produced a steady stream of hydrogen nuclei with an energy of about half a million volts. They were carefully measuring the quality of the stream, in no hurry to begin doing nuclear experiments. On the morning of April 13, Rutherford came into their room, saw what they were doing, and lost his temper. He told them to stop wasting their time and do some science. The next day, Cockcroft was occupied with other business. Walton was alone in the laboratory, ready to do the first experiment, using his hydrogen nuclei to bombard a target made of the light metal lithium. The result was spectacular. The lithium nuclei were split in two and fell apart into pairs of helium nuclei.

用了五年时间，考克饶夫和华尔顿建造出了第一台能运行的加速器，最终，在1932年，他们制造出了能够提供稳定氢粒子流的加速器，粒子能量大约为50万伏特，他们并没有急着做核试验，而是精心测量了粒子流的性质，4月13日清晨，卢瑟福来到他们的房间，看到他们还在测量，大发雷霆，告诉他们停止浪费时间，开始科学研究，第二天，考克饶夫就被安排了其他事情，只剩华尔顿一个人在实验室里，准备做第一次实验，用他的氢粒子流轰击用轻质金属锂作的标靶，结果极为壮观，锂原子被分裂成两半形成一对氦原子，氦原子释放出的能量比氢原子注入的多达三十倍！

I will endeavour to find you some assistance.

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
