谁能帮我翻译成英文啊！急需！！！

希望英语好的各位大虾帮偶翻译成英语好么？
在力学中常把物体相对于某一稳定平衡位置有一个微小振幅的自由系运动叫做简谐振动。简谐振动是最简单、最基本的振动，也是一种理想的振动，一切复杂的振动都可看成是由许多不同频率不同振幅的简谐振动所合成。根据简谐振动的定义可以判定物体的振动是否是简谐振动，利用振动方程可以求出简谐振动的速度、加速度、及振动的能量。
简谐振动的物理模型有很多，其中比较有代表性的有弹簧振子，单摆，此外还有复摆，圆锥摆等。虽然运动的形式不同，但是，其运动学方程都遵循简谐振动的定义式，具有相同的特征。
简谐振动的描述方法有很多：三角函数表示法，旋转矢量法，图线表示法，向量表示法等。这些方法都是比较直观的描述方法，利用这些方法可以很容易地看出简谐振动的相位，位移及运动方向。这些方法一般都是从振子的微分方程出发，直接解微分方程得到简谐振动的特征。

注：不会的就不要帮忙了，网站上翻译的也不行，偶试过了的，被老师给一个大XX判了死刑，呜呜~~

Answer 1

Mechanics are often the objects in relation to a stable equilibrium position of the freedom of a small amplitude harmonic vibration is called the Department of Movement. Simple harmonic motion is the simplest, most basic of vibration, the vibration is also an ideal, all the complexity of the vibration can be seen as different from a number of different amplitude of the harmonic vibration frequency synthesized. According to the definition of simple harmonic motion can be determined whether the object is simple harmonic motion of the vibration, the use of simple harmonic motion vibration equation can be derived speed, acceleration, and vibration of energy.
Simple harmonic motion, many physical models, which are more representative of spring oscillator, pendulum, in addition to compound pendulum, such as conical pendulum. Although different forms of movement, but its kinematics equations follow the definition of simple harmonic motion style, with the same characteristics.
Description of simple harmonic motion, many methods: a trigonometric function that law, the rotation vector method, Chart representation, such as expression vector. These methods are described in an intuitive way to compare the use of these methods can be easily seen in the phase of harmonic vibration, displacement and the movement direction. These methods are generally from the differential oscillator, the direct solution of differential equations to be characteristic of simple harmonic motion.

Answer 2

The location an object is often balanced in Mechanics relative to some one stability liberty having a tiny amplitude being that motion is called simple harmonic vibration. Simple harmonic vibration is simple , the most fundamental vibration , is also one kind of ideal vibration, all complicated vibration considers as what the simple harmonic vibration being that different from many frequency is unlike amplitude composes. The definition according to simple harmonic vibration can decide if the object vibration be simple harmonic vibration , make use of vibration equation to be able to seek speed , acceleration, and the energy vibrating producing simple harmonic vibration. The simple harmonic vibration physics model has many , having the spring vibrator , simple pendulum , still having compound pendulum , cone pendulum besides and so on having representativeness among them comparatively. Although the form moving is different,whose kinematics equation all abides by the simple harmonic vibration definition style , has the identical characteristic. The simple harmonic vibration description method has many: Circular functions representation , revolution vector law , picture line representation, vector representation waits. These method all is comparatively penetrating describe method , make use of these method to be able to perceive the simple harmonic vibration phase very easily, displacement and direction of motion. Being to set off from the vibrator differential equation like these method , solve differential equation directly getting the simple harmonic vibration characteristic.
