A standard expected value model for multi-objective multi-stage transmission planning is presented to realize the transmission optimal planning with the control of line overloading risks. In this model, a constraint of overloading risks is built with expected value and standard deviation of random line active power and two objectives are given as expected value of the average power loss and discount value of the investment cost. By modeling uncertain informations with probability theory, the probabilistic DC power flow is adopted for the correlated calculations among random variables in the planning model.4 A novel multi-objective transmission planning approach that considers transmission investment profit is proposed. Requests for transmission investment profit and social welfare are involved in the proposed planning approach.

Based on the artificial neural network model, the sensitivity analysis on each variable of model shows that the effect of ring index of diameter at breast height of Cunninghamia lanceolata on sun-spot is even, and the effects of auto-correlated factors of sun-spot on sun-spot are sensitive, which shows that three variables all have significant effects on sun-spot.

并对网络模型中各变量进行灵敏度分析，分析表明，杉木胸径生长的年轮指数对太阳黑子相对数年平均值影响较平坦，而太阳黑子自相关因子Yt-4和Yt-2对太阳黑子相对数年平均值影响较灵敏，3个因子对太阳黑子相对数年平均值均存在一定的影响。

This paper aims to study some important problems of clutter modeling and simulation, which include as follow:According to the principle that each quadrature component of K-distributed clutter can be modeled, exactly or approximately, by a weighted sum of products of two independent Gaussian variables, a new method for modeling and simulation of correlated coherent K-distributed clutter is presented.

The prevalence of character limitations was significantly higher in left-behind children (64.4%) than in non-left-behind group (47.6%; x^2=21.25, P.01). The depressive symptoms score of the left-behind children was significant higher (40.4%) than that of the non left-behind group (27.8%;χ^2=13.78, P.01). Scores of EPQP and EPQN were positivey correlated with scores of CES-DC scale (r=0.198, r=0.372; P.01). Ten variables influenceing the personality traits and depressive symptoms of children were age, sex, peer interaction, parents' expectation for children, consanguineous marriage of parents satisfaction to family condition, self-estimate, academic achievement, frequency of meeting with the parents, and psychiatric history of family.

结果 留守儿童精神质、神经质得分分别为(5.25±2.56)，(9.48±5.33)分，高于非留守儿童的(4.79±2.16)，(8.10±497)分，差异有统计学意义(P.05， P.01)；留守儿童个性偏差检出率为64.4%，高于非留守儿童的47.6%(χ^2=21.25， P.01)；抑郁症状检出率为40.4%，高于非留守儿童的27.8%(χ^2=13.78， P.05)； CES-DC得分(18.24±8.65)分，高于非留守儿童的(15.85±7.45)分(P.01)；相关分析提示，EPQ中精神质、神经质量表与CES-DC呈正相关(r=0.198， r=0.372， P.01)；儿童性别、年龄、同伴交往、父母近亲结婚、家庭状况满意度、自我评价、学习成绩、与父母见面频率、父母期望、精神病家族史共10个变量影响着留守儿童的个性和抑郁情绪。
