In this research a new mathematical model - cubic polynom with two given derivatives at end points - was proposed which can good match the S-shpae curve.This model has a number of analytical features:describing the geographic phinomena prosesses in three hierarchies (textural fractal,structural fractal and state fractal); the boundary values of the structural fractal can be considered as the boundary values of interval of scaleless.

在研究中提出了扩展分维表达函数：带导数三次多项式，它能很好地表达反S形分布曲线，具有一系列解析特征：可从三个层次（纹理分形、结构分形和态势分形）上描述地理现象或过程；其中结构分形的边界可近似地看作是非扩展分维无标度区的上下界。

Its physical properties were no effect after doping; XRD and energy spectrum analyzer showed characteristic peak of Al.

掺杂前后该材料的物理性能无太大变化；利用XRD与能谱仪观察到了铝元素的特征峰。

Typical bands were used to analyze relation with ecotypes and characters of fruits, indicating that there was no relation between typical bands and ecotypes, but some extent relation between bands and characters of fruits existed. If all cultivars were divided into freestone and clingstone, melting and nonmelting, both freestone (ratio shared total survey, 41/56=73.2%) and clingstone (ratio shared total survey, 33/79=41.8%) appeared in the loci of S_(167)-1050 bp linked marker raised by Warburton et al. It was apparently not strong linkage between the marker and the character, and exchange rate of genes was high. If combinations of S_(167)-850bp and S_(167)-1050bp or S_(167)-850bp and S_(167)-1400bp were used to distinguish characters of fruits, 6 freestone accessions without clingstone ones and 6 melting accessions without nonmelting ones displayed in the first combination of markers, 20 clingstone accessions and 2 semi-freestone ones without freestone ones appeared in the second combination of markers.

通过典型带对不同生态型、果实性状为类别进行分析，结果未发现有与生态型相吻合的特征带出现，而将供试所有品种按离核、粘核和溶质、不溶质划分归类，供试品种在Warburton等得到S_(167)-1050 bp处粘离核分子标记，出现既有离核(占供试离核41／56=73.2％)，又有粘核(占供试粘核33／79=41.8％)，可见此连锁标记连锁性不强，发生交换的机率较高，而S_(167)-850bp带和S_(167)-1050bp带同时出现时，该组包含6个离核，无粘核品种；6个溶质，而无不溶质。S_(167)-850bp和S_(167)-1400bp同时出现时，包含20个粘核品种和2个半离核品种。

Firstly, the approach formulates a cost functional to turn the inverse problem into a constrained minimization problem according to least squares criterion, then the resulting constrained minimization problem is transformed into an unconstrained minimization problem by using a penalty function technique, and then the closed Fr chet derivatives of the Lagrange function with respect to the properties are derived based on the calculus of variations, finally, one can solve the resulting problem by using any gradient-based algorithm and the finite-difference time-domain method.

该方法首先以最小二乘准则构造目标函数，将逆问题表示为约束最小化问题；接着应用罚函数法转化为无约束最小化问题；然后基于变分计算导出闭式的拉格朗日函数关于特征参数的Fr chet导数；最后借助梯度算法和时域有限差分法迭代反演德拜模型参数。
