Then the article starting from the activity, which relates the person with exterior nature,namely the human society work practice, elaborates the nature which worked as the foundation of humanity labor,and the human could not leave it and are bringing it into line with the nature as the work essential factor of labor process; The realistic nature similarly also cannot leave human as persons work creation, and this is the question of two aspects.The thesis has analyzed the work and natural relations in the agricultural society and in modern industry society ,and obtains the conclusion that the different ecology values can form under the different production method. This article criticizes disassimilation work in the capitalist society not only causes the disassimilation relationship between the human, but also creats the disassimilation which human and nature related, and proposes the communism society not only is the society in which the contradictory exploitation between human and nature is solved, and the contradictory relation between human and nature is also solved.

的结论；其次从人与外部自然相联系起来的是活动，即人类社会劳动实践出发，论述了自然界作为人类劳动的基础，人类须臾离不开它，人是把自然界作为劳动的要素而纳入自己的劳动过程的；现实的自然界作为人的劳动创造同样也离不开人，这一个问题的两个方面，并分析了在农业社会中劳动与自然的关系和近现代工业社会中劳动与自然的关系，得出在不同的生产方式下会形成不同的生态价值观的结论，批判了资本主义社会的异化劳动不仅造成了人与人之间关系的异化，还造成了人与自然之间关系的异化，提出共产主义社会不仅是人与人之间对立矛盾的剥削与被剥削关系真正解决的社会，也是人与自然之间破坏与被破坏的矛盾关系真正解决的社会的论断。

The results showed that there was good linear relation of cumulative evaporation with square root of evaporation time, and the coefficients of them had good relation with the open hole ratio, thus the two-factor function of cumulative evaporation was obtained.

累积蒸发量与时间平方根的线性关系符合Gardner的理论关系，而两者关系的系数又与覆膜开孔率之间存在良好的对数关系，从而得出了累积蒸发量的两因素函数关系。

In order to determine further the profile of scrolls,the structural characteristics of superchargers with double-sided scrolls were analyzed and the principle of determining initial involute angle s was presented on the conditions of definite initial involute angle s,radius of base circle,and depth of scrolls.

在渐开线起始角、基圆半径和涡旋齿深度确定的条件下，为进一步确定涡旋齿的齿形，对双侧涡旋增压器的结构特征进行分析，提出始端渐开角的确定原则。通过吸气腔和排气腔的容积计算，结合回转角与渐开角的关系，给出涡旋齿始端和终端渐开角的计算方法。结果表明：该计算方法能较准确地确定涡旋盘的结构尺寸，从而可估算出整个压气机的尺寸是否满足汽车上有限的安装空间
