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.

In Chapter 5,the pyrolysis of substituted six-membered ring model compound 4-methyl pyridine has been investigated.Instead of detail theoretical analysis of the reaction mechanism,the general results have been proposed from the products distribution and the combination of the pyrolysis investigation of its analogous pyridine.The major products are H_2,C_2H_2,C_4H_2,C_3H_3N and HCN,here HCN is not a primary initial product at low extent of decomposition.The mole fraction profiles of products have been obtained from the near threshold ionization.The pyrolysis of 4-methyl pyridine is initiated from the methyl abstraction and hydrogen abstraction procedures which are associated with the understanding of the soot formation and the NOX precursor correspondingly.
主要产物为H_2,C_2H_2,C_4H_2,C_3H_3N和HCN,其中HCN为非低温时的热解产物;通过近阈值电离并导出物种随温度变化的摩尔分数曲线,更详细地定量地描述了产物随温度的变化。4-甲基吡啶热解主要从母体脱甲基和脱氢两个初始反应出发,一种趋势是形成大质量数的苯并或杂环的多环化合物,有助于了解炭黑形成过程中的复杂化学过程;另一趋势是开环生成小的碳氢和腈类物质,实验得出的含氮物质的种类及随温度变化有助于了解NO_x的前驱物质的形成及其变化规律。

DIPSO incorporates the dynamic mutation, multi-subpopulations methods of IPSO, and changes the heights and the positions of the peaks by variable parameters and chaotic model. This algorithm uses multi-subpopulations to search for the highest peak in order to track the dynamic environments. Furthermore, DIPSO apperceives the changes of the environment by tracking the fitness value of the global optimal particle.

Prominence a wide variety of shapes and movement characteristics, in general can be divided into four categories:(1) quiet prominence, change is slow, longer life expectancy, up to the number, and with the presence of sunspots related to sunspots for a long time, it is also a little more;(2) the activities of prominence, from a quiet prominence changes years, the movement is faster, but lower than the sun's surface escape velocity, so mostly circular, the material eventually thrown off the plane back to Japan;(3) the outbreak of prominence, activities of the most intense one, and sometimes velocity can exceed the Sun the surface escape velocity, reaching 100 km D seconds, or even higher altitudes of up to one million kilometers, 20,000 kilometers thick;(4) crown-shaped prominence, looks like clouds, is a rather exceptional prominence.
日珥有各种各样的形状和运动特征,大体上可分为四类:(1)宁静日珥,变化缓慢,寿命较长,可达数目,并与黑子的存在有关,黑子多时,它也多一些;(2)活动日珥,由宁静日珥变化而来,运动速度较快,但低于太阳表面逃逸速度,因此多为环形,抛出的物质最终仍落回日面;(3)爆发日珥,活动最激烈的一种,有时运动速度可超过太阳表面逃逸速度,达100公里D秒,甚至更高,高度可达上百万公里,厚达2万公里;(4)冕形日珥,貌似浮云,是一种比较特殊的日珥。
