A method of time delay estimation by two times spectral analysis, where the time delay is the time interval between peaks of spectrum of the cross power spectral density, is proposed in the paper. It can be used to estimate time delay of not only single target but also multi-target without unwrap.

We construct a family of iterative mappings, which yield cyclic windows of variant size in the dynamical plane by incorporating cosine functions and non-linear angle variables with parameters. Chaotic attractors and filled-in Julia sets in the different cyclic windows are created by establishing the coordinates of any cyclic windows and the maximal window, then clarifying the relationship of corresponding points between these cyclic windows. The respective images in different windows are continuous but with individual structures.

该算法采用余弦函数及含参的非线性角度变量构造一族使动力平面上各周期窗口的尺度变化的迭代映射；通过计算任意周期窗口和最大周期窗口得出窗口间相应点之间的非线性对应关系，并构造出各周期窗口中的混沌吸引子和充满Julia集，其图案是连续的且结构不同的；选用不同的周期窗口作为基本计算区域，使之与正方形像素矩阵对应，并构造出基本图元，实现了用一个映射构造出多个平面排列图案的算法。

The result shows that: The variation rhythm of the sensitivity index changed unanimously for Jensen,Blank and Stewart water production functions of spring wheat in Liangzhou city,the volume is small in the former stage,then become large at the middle stage,and less at the last stage. Jensen and Stewart water production functions are better of spring wheat in Gulang County in 1987-1989. The Variation rhythm of water deficiency sensitive index is unanimous: the volume are small at first,then large at middle,and diminish at last. The Variation rhythm of water deficiency sensitive index is unanimous in Jensen,Blank and Minhas of flax in Liangzhou county in 1987-1989. The water deficiency sensitive index in Gulang district in 1987-1989 models bad,are too many minus. 3 Establishing the non-linear model to definitive the irrigation quota and dimension of single crop,according the three prototype Precipitation,allocating the limited water optimally according to full water supply,95 percent,75 percent and 50 percent. Economy benefit is the biggest aim function,so getting three groups for irrigation quota,irrigation dimension and benefit,the biggest benefit is the most optimal result.

结果表明：1985-1986 年凉州春小麦Jensen 模型、Bl(来源：10a1ABC论文网www.abclunwen.com)ank 模型和Stewart 模型的敏感指数变化规律接近一致，在前期较小，中期增大，最后再减小。1987-1989 年古浪春小麦水分生产函数以Jensen 模型和Stewart 模型拟合较好，其敏感指数变化规律比较一致，敏感指标值前期较小，中期增大，后期又减小。1983-1985 年凉州亚麻水分生产函数以Jensen 模型、Blank 模型和Minhas 模型敏感指标值变化规律比较一致：先减小，后增大，最后再减小。1987-1989 古浪亚麻敏感指数出现负值较多，模型拟合较差。3 建立单作物种植条件下灌溉定额与灌溉面积的确定的非线性规划模型，将有限的水量按照充分供水，95%、75%和50%供水来分配水资源，以经济效益最大为目标函数，得出三组灌区灌溉面积和效益结果，其中以效益最大为最优解。
