tanh的翻译

Many new methods for obtaining the exact solutions of NLEEs are proposed, such as the homogeneous balance method, the trial function method, the tanh-function method, the sine-cosine method and Jacobi elliptic function expansion method, etc.

许多新的寻找非线性演化方程的精确解的方法被提出，如齐次平衡法、试探函数法、双曲正切函数法、sine-cosine法以及Jacobi椭圆函数展开法等。

The basic principle of our algorithm is based on such observation that a majority of meaningful solitary wave solutions can be expressed as the polynomial forms in terms of "bell-shaped" function sech and "kink-shaped" function tanh which possessing localized property.

算法的基本原理是基于这样一种观察，即非线性波方程绝大部分有物理意义的孤立波解都可以表示成具有局部性特征的钟状函数-sech和扭状函数-tanh的多项式。

Secondly, in order to overcome sigmoid function incidental to lead to proneness to yield minimal local results in the train course of the hidden unit and output unit, which is tanh ( x) a new threshold activation function is applied.

其二，训练过程中对隐层和输出层采用了双曲正切阈值激励函数进行训练，解决了Sigmoid函数在0和1附近易陷入平坦区的情况。
