采用逐步回归分析发现：遭受排挤事件和因对方态度损伤自尊事件对沟通化解应对方式具有显著预测作用；遭受排挤事件和因对方态度损伤自尊事件对伤害对方应对方式具有显著预测作用；遭受排挤事件和性别变量对反思应对方式具有显著预测作用；物品使用事件和年级变量对争执应对方式具有显著预测作用；因对方态度损伤自尊事件和性别变量对认知安慰应对方式具有显著预测作用。 - The process of setting up the ship form main dimensions is mainly relied on the multivariate and stepwise regression in the past which based on the massive subsistent data including the main dimensions , light weight , storage capacity , stability and total cost and so on . with the appearance of the technology of ann and ai , the bp network is used predicting and simulating in all kinds of fields
船型主尺度要素的建立，以前主要采用的是基于数理统计理论的回归分析方法，如多元回归分析方法和逐步回归分析方法等，它是建立在大量现有实船数据的基础之上，对船型主尺度要素、空船重量、舱容、稳性和造价等要素进行统计回归。 - Three models are established first by linear regression analysis with the experiment data of practical ship plate . through comparisons between the three models obtained , the effect of each parameter on the local contraction , is examined , the conditions of application are estimated , and explanations are given to the error induced in the models obtained . 3
首先选择影响成型的主要变形参数，运用数理统计原理及逐步回归分析方法，对945钢板测试数据进行回归分析，建立了三种变形参数的回归模型，最后比较分析这三种回归公式的回归效果，考察回归公式中各变形参数对变形量的影响程度，给出适用条件，分析误差项产生的原因。
