等价函数

To avoid the trouble to construct the basis functions, we introduce a Lagrange multiplier into the variational formulation to replace the constraint condition for the basis.

本文采用同样的思路用Galerkin 边界元方法求解带有约束条件的与第一类Fredholm 间接边界积分方程等价的变分方程，为避免构造基函数时约束条件的限制，我们采用Lagrange 乘子法，把约束条件放入变分方程中去，形成扩展的变分方程，用线形单元离散后求解。

Using discrete Poisson kernel,Boza and Carro defined〓inlat-ely,as well as proved the equivalence with〓inandeach other.Particularly,with the idea of atomic decomposition,Boza and Carro inestablished the atomic Hardy space on Z,and showed the equivalence with〓.

最近，Boza和Carro在中用离散Poisson核〓和一类Schwartz函数分别给出了离散Hardy空间的定义，并证明它们与和中的〓相互等价。

The notion of weak fuzzy similarity relations,a generalization of fuzzy similarity relations,is used to represent indiscernibility of elements.

为此提出用模糊相似关系和弱模糊相似关系的概念来代替等价关系，同时引入了弱模糊相似关系的相似度概念和相似类概念，定义了基于弱模糊相似关系的广义粗糙集及标准的广义粗糙集上下近似；研究了两对上下近似算子的性质，讨论了3种粗糙隶属函数的性质并验证了它们的性质。

According to the equivalence of traffic forecasting and function estimating and approaching,the essay puts forward a method of short-term traffic forecasting which is based upon wave decompounding and support vector regress.

基于交通流预测问题与函数估计和逼近问题是等价的的思想，提出一种基于小波分解-支持向量回归的短时交通量预测方法。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
