The basic thought and calculation method of the nearest neighbor bootstrap regressive models ( nnbr ) in modelling the single and the multiple factor prediction were introduced 摘要介绍了最近邻抽样回归模型( nnbr )进行单因子和多因子预测建模的基本思想和算法。
The submodel for target yield prediction was developed through integrating the effects of cotton radiation - temperature - water yield potential , soil fertility , average yield of last three years and production technique levels 产量目标知识模型是以棉花光温水生产潜力的估算为基础，通过量化土壤肥力、历史产量水平和生产技术水平等多因子对皮棉产量的影响而建立的。
Usually , calculator or microsoft excel is used to do a mass of calculation or statistic calculation in data processing , but with which cannot execute special arithmetic or nonlinear case 在进行实验数据处理时经常要进行大量的计算，一般利用计算器和microsoftexcel软件可以进行公式计算和统计处理，但对于特殊算法计算和复杂数据处理，尤其是多因子、非线性问题的解决则是一大难题。
According to the intensity of the ecosystem service function and the sensitive level for ecological environment , this paper take the method of synthetic superimpose analysis of many factors , divide the different dimension by ecology protection importance 根据生态系统服务功能强弱和生态环境敏感性程度的不同，采取多因子综合叠加分析的方法，按生态保护重要性的大小划分不同的生态功能区。
Although osteoporosis is multifactorial , physical activity is important to the skeleton at any age because the associated weight - bearing and muscular activity stimulates bone formation and increases or at least stabilizes bone mass while immobilization leads to rapid bone loss 而骨质疏松症虽属多因子疾患，然历来文献已指出身体活动对骨骼的影响适用于任何一个年龄，其带来的承重与肌肉收缩效应通常能提供有效的外力以刺激骨形成或稳定骨量。
The dvm behavior of the copepod is controlled by multi - factors . the diversified migrating patterns show that copepod is the active decision - maker , which can achieve the optimal food intake during its avoiding predation by performing the normal dvm ; 2 足类的昼夜垂直迁移行为是由多因子控制的，其迁移模式的多样性表明，桡足类是主动的决策者，通过识别环境因子的变化，桡足类借助于常规的昼夜垂直迁移在逃避捕食压力的同时能够实现最优的食物摄取量； 2
Cylindrical cup is a typical axial symmetrical part , though the deformation of material is simple in drawing process , but during the drawing process , exists a lot of influence factors ( including workpiece material character itself as well as each technological parameters ) , and they restrict mutually between the factors . so how to calculate the limiting drawing rate of a cup becomes a complicated nonlinear and multi - gene question . to predicting limiting drawing rate of the cylindrical cup accurately indeed is a very complex subject 筒形件是典型的轴对称拉深件，在拉深过程中材料的变形虽然相对简单，但是在生产过程中，由于影响因素很多（包括工件材料本身性能以及各个工艺参数） ，且各种因素之间相互制约，故如何准确地计算筒形件拉深极限就成为一个复杂的非线性多因子问题，要真正准确预测筒形件极限拉深系数也是一个非常复杂的课题。
This paper includes five parts . the first is to review the study on the subject ; the second is to discuss the characteristic of chian ' s stock market . . the change of money - admitted policy and the questions on the study . the third is to verify the size effect in china ' s stock market by using correlation test and regression test on the bases of four different criterions , each criterion will be applied with two time - series methods . the fourth is to summary the main character of four different criterions , and apply joint test to the criterions that were proved the best concerning the size effect . the illiquidity risk was introduced to the study , the indexes of turn - over rate and the fluctuation of turn - over were used here . however , other factors that may influence the invest return rate as circulating rate and size were also included . according to the result , the size effect will be interpreted . the fifth is to summary the size effect and its explaination , and then to provide some useful invest strategies based on the conc lusion above 论文分五部分，第一部分对小公司效应的有关研究文献进行回顾;第二部分我国股票市场的状况、资金供给政策的变化和我国股票市场实证的相关问题进行论述;第三部分对我国股票市场的小公司效应按照四种不同的规模标准分类，每一种标准均分两种不同的统计周期分段标准进行实证分析;第四部分小结不同的规模分类、不同统计周期分段的统计结果特征，然后对小公司效应最明显的规模分类标准进行多因子联合回归分析，这里引入了流动性风险因素，其用换手率和换手率波动指标来衡量，还分别引入了其它影响投资收益率的因子，分别是规模、流通比例。
In this paper , the multifactors - electrical , thermal , cool and thermal circulation of accelerating ageing experiment based on the stator bar of 220mw turbine generator has been conducted in the laboratory . the results of the experiment show that there has not fixed rule between maximum pd quantity and insulation , but the increasing of maximum pd grads increase along with ageing time of insulation 本论文通过对220mw的汽轮发电机真机线棒进行电、热、冷热循环等多因子老化试验，发现局部放电的最大放电量与绝缘老化时间之间没有固定的规律可寻，而最大放电量的梯度随绝缘老化时间的增大而增大。
