The object of this study is to simulate the washer operation of drum washer and horizontal belt washer by varying some process variables, such as dilution factor, pulp mat consistency, washing liquor temperature and basis weight, with a laboratory pulp tester. The aim is to find out the effect of these variables on the washing efficiency and determine the specific gravity of black liquor.

Randomly adopted 1000 students from 6 country middle schools and 4 country elementary schools, and get 813 available subjects. We can find that: the percentage of Left-behind children is the largest in the whole children, especially Left-behind children who have only one parent; and mentally healthy situations of Left-behind children are poorer than those who are not, the poorest are children who are looked after by compeers or even no rearings; the situations of children who have been Left-behind children also are not so good, there are significant differences mentally healthy between them and those who have not been, while anxiety scores are only a little lower. And there are differences in sex, grade, quarter, single or not and years parents being out among those who are Left-behind children. There are differences of parenting styles among different styles of children caring. Totally speaking, the scores on positive parenting styles of no left-behind children(such as warmth of father and mother) are higher than those who are and who have been left-behind children, but the scores are obviously lower on negative parenting styles such as punishment from father or intervening punishment from mother. The regression equation of anxiety scores on left-behind children set by parenting styles also depends on children caring styles. Positive parenting behaviors of parents and caring people have positive influences on mentally healthy of children, for instance, some supporting and mood warmth., while some negative behaviors such as rejection have negative influences.

随机抽取了江西省的6所农村中学和4所农村小学，调查学生被试共计1000人，有效被试为813人，对调查数据进行分析后发现：留守儿童所占的比重在全体儿童中最大，尤其是单亲看护人的留守儿童；而且，留守儿童的心理健康状况也显著低于非留守儿童，情况最差的是同辈看护或无看护的留守儿童；曾留守儿童的心理状况也不尽如人意，它与非留守儿童的心理健康差异达到了显著水平，心理焦虑总分只是稍低于留守儿童总体；并且，留守儿童的心理健康同样存在着性别、年级、独生与否、住宿与否以及父母打工年数的差异；不同看护类型的留守儿童父母教养方式存在着差异，总的来说，非留守儿童积极性的教养方式(如父亲温暖、母亲温暖等)得分要高于留守儿童和曾留守的儿童，而在很多消极性的教养方式如父亲惩罚、干涉，母亲干涉惩罚等等上，留守儿童与曾留守儿童的得分又要显著高于非留守儿童；家庭教养方式对留守儿童焦虑总分的回归方程视儿童的看护类型而定，父母和看护人的一些积极性的抚养行为对儿童的心理健康有着积极的影响，比如情感温暖或者支持温暖等，但是一些消极的比如拒绝等对留守儿童的心理健康就有负面的影响。
