卷积定理

A combinatorial identity is obtained:=:~z 2r扟32-rn-iJ As main result of this paper, in section two, the convolution梩ype identities emerge from our discussion about Lagrange formula whom in author 憇 view can be taken as the inherent characteristic of Lagrange formula but have been ignored fOi so long time.

第一章对拉格朗日反演在Riordan群理论中的应用进行了介绍，证明了一个组合等式：第二章通过对拉格朗日反演定理本身的分析，得到一个对任意的形式幂级数都适用的三个拟卷积公式，这些公式体现了任意能在零点解析的函数的内在性质。

In the basic theory, the basic STFEM theory is perfected, the variation principle in form of a convolution included is given and proved.

在时空有限元法的基础理论方面，完善了时空有限元法的基础理论，给出并证明了具有普适意义的含卷积运算的变分定理。

A simple method derived from an identity commonly found in polynumial theory is used to deconvolve the system input. The experimental results show the validity of the method.

在盲辨识的基础上，利用多项式互质的一个判别定理，通过解卷积求出SIMO-FIR系统输入，最后通过实验验证了算法的有效性。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
