不变

And my biggest experience is that tackle the varation by stationing on the fundamental purpose of learning language - making use of language or application of language.

所以我最大的感想就是要&以不变应万变&，以把握对英语的应用为目的来学习这门语言。

Suppose you are running a car at a constant speed with a constant curvature, if you then keep the steering wheel in the same position and increase the car speed gradually, then if the car wants to run on a circle with a smaller radius the car is said to be oversteering, if it remains on the same radius it is neutral and if the car goes to a wider circle it is understeering (for that speed and curvature!).

假设你以固定的速度沿固定曲率的圆周驾驶车辆，然后你保持方向盘角度不变，逐渐增加车辆的速度，此时车辆行使的半径如果变小，称为转向过度（在这个特定的速度和曲率下！）。这个测试还有不同的做法。

Using this method, wide dimming range can be achieved with narrow frequency range and constant DC link voltage. And the lamp current keeps perfect sine wave all the time, which means low lamp current crest factor is obtained. Its validity is verified by simulation and experiment.

本章最后提出了一种基于T型滤波器的新型的调光方法，采用此方法可以在保持逆变器直流母线电压和开关占空比不变的情况下，只需很窄的频率范围就能达到非常宽的调光范围，而且在整个调光范围内灯电流都基本上是完美的正弦波，这就意味着可以始终保持很低的灯电流波峰因数，仿真和实验结果充分验证了它的优点。

He must teach himself that the basest of all things is to be afraid; and, teaching himself that, forget it forever, leaving no room in his workshop for anything but the old verities and truths of the heart, the old universal truths lacking which any story is ephemeral and doomed -- love and honor and pity and pride and compassion and sacrifice.

他必须教会自己这世界上最卑鄙的事情便是害怕和学会永远的忘却。如果他忘却了精神上亘古不变的真理和事实，忘却了没有爱，没有尊重，没有同情，没有自尊，没有怜悯，没有奉献的世界任何事情都将变得短暂和既定的真理，如果他忘记了这些，他就不再为自己的创作空间留有丝毫的余地。

T hings do not change;we change.sell your clothes and keep your thoughts.

万物不变，是我们在变。你的衣服可以卖掉，但要保留你的思想。

The calculating results indicate that surrounding rock initial stress has an obvious influence on interior force of invert center, interior force increases with the vertical force increasing in both side of invert center, and decrease with horizontal force increasing in interior side , unchangeable in outer ...

计算结果表明，围岩初始应力场对仰拱受力有明显影响，随着竖向压力的增大，仰拱中心的内、外侧应力均增大；随着水平压力的增大，仰拱中心内侧应力减小、外侧应力基本不变；减小复合衬砌结构中初期支护厚度以及变刚性接头为柔性接头均会改善仰拱受力。

After the phase inversion point,the dynamic rheological parameters increase greatly with adding water.

实验结果表明，体系在相反转点前表现为牛顿流体行为，粘度几乎不变﹔相反转点时，体系粘度增加幅度很小，体系的有关动态流变参数(剪切储能模量、损耗模量和复数粘度)均出现极小值，将此归于局部连续水相的润滑作用﹔进一步加水，体系的动态流变量增加，意味著相反转在相反转点后仍在继续进行。

Thongs do not change; we change. Sell your clothes and keep your thoughts.

万物不变，我们在变；卖掉你的衣服，保留你的思想。

We will ,as we have always done ,use our never-changing warmth to stick to the aim of "it is our perpetual pursuit to bring benefits to consumers" and forge ahead indefatigably.

日新月异的今天，&精益求精&是我们始终不变的目标，我们将一如既往，用我们永不褪变的热诚，恪守&让消费者受益是我们永恒的追求&的宗旨，不懈奋进！

He a day before accept of teach,, constant black become green, crossing-sweeper red all of the signal beacon became green signal beacon.

他接受前一天的教训，，不变黑色变绿色，把十字路口的红色信号灯全变成了绿色信号灯。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.

这是凯特，那个是爱朗。
