This article applies the basic principles of the general and special entropy, puts forward the concept of High\|entropy system and its entropies. Sometimes, the entropy functions have been defined, and their mathematical models have been constructred, and methods of quantification. Specially. Taking the Mining System as an example, the quantification method of the operating entropy is given under the synthetic action of the man\|made entropy, machine entropy, natural entropy and environmnet entropy. Therefore it enriches the theoretical and applied systems of the general and special entropy.

研究并比较了重庆市铁山坪马尾松和观音桥樟树降水的化学特征,分析了大气降水的化学物质输入及其降水淋溶对森林生态系统物质循环产生的影响,并对各种离子组分的来源进行了初步解析.结果表明:针叶林穿透水有进一步酸化趋势,而阔叶林可以减缓酸化作用.大气降水和穿透水是养份输入的主要形式,其中以穿透水养份输入为主.穿透水中N元素可能被吸收,其它营养元素则主要来自干沉降洗脱和植被的淋溶.

The stabilities of the complexes of three pyridine-like ligands with M(II)(ATP)^(2.) and M(II)(M=Ni,Co)were studied by spectrophotometry and by comparing the stability constants of the ternary complexes with these of the binary complexes.A stacking interaction between the pyridine ring and the purine ring of ATP is *** general existence of the stacking interaction encourages us to interpret the antitumor mechanism of a new class of antitumor drugs.
