For efficient utilization of phosphorus—rich rhodochrosite and complicated sulfides, we have carried out some studies on enrichment of manganese, dephosphorization and bio-catalytical oxidation of sulfides supported by NSFC (No. 59374150, 59774010), the main contents include: properties of Huayuan Manganese ore; microorganisms preparation of dealing with manganese ore; physiological and biochemical properties of microbes used; the mechanism of microbes function to manganese ore; the separation, tameness of Thiobacillus ferrooxidans and its nutriment; bio—catalytical oxidation mechanism of sulfides; extraction of gold by bio—catalytical oxidation—cyanidation.

为解决我国储量丰富的高磷贫碳酸锰矿石和复杂硫化矿有效利用中存在的问题，我们在国家自然科学基金委员会的资助下（No.59374150，No.59774010），以花垣锰矿石和黄铜矿、黄铁矿等为研究对象，进行了高磷贫碳酸锰矿石的微生物富锰降磷和生物催化氧化硫化矿等的研讨工作，内容包括：花垣锰矿石的性质研究；富锰降磷微生物的筛选；试验用微生物的生理生化特性及富锰降磷机理探讨；催化氧化硫化矿细菌的分离、驯化及营养条件确定；生物催化氧化硫化矿的机制；金的生物催化氧化—氰化提取。

Contemporary natural science, especially the development of the foundation academics at the macro view and tiny view two directions up, all having already outrun what daily life be familiar with and used Newton the classic mechanics and rigid space far and far can explain of scope.

Only when the government and the whole nation pay attention to basic education, the excellent talents of natural science and social science, creating room for giving full play to their ability and wisdom, will china have the hope of achieving The Nobel Prize.

当政府与全民族都能重视基础教育、自然科学与社会科学的杰出人才了，并给他们创造发挥才干的空间，诺贝尔奖才有希望落地中国。

It is pointed out that its research object is the dry land (seabeach and inland water place are included) in the earth; land reclamation is not only an engineering technique, but also a synthetic applied science intersected by natural sciences and social sciences.

认为：土地复垦的研究对象是地球表层的陆地部分（包括海洋滩涂和内陆水域）中由于人为或自然营力原因遭到直接或间接破坏而丧失了原有利用价值的、需要恢复其用途的部分；土地复垦是一门工程技术，属于自然科学和社会科学交叉的综合性应用科学技术范畴。

The Second Law of Thermodynamics is often regarded as one of science's most glorious laws. And also one of them the most difficult to understand.

热力学第二定律常被认为是自然科学最有名的定律之一，也是其中最难理解的定律之一。

During the late 20 years of the 20th century, the academic circle in China developed an overall and deep self criticism over those phenomena of exclusion, negation of the traditional research method, natural scientific method and humanistic method from the 1950s～1970s.

20世纪后 2 0年，中国学术界对 5 0～ 70年代排斥否定传统研究方法、自然科学方法、人文主义方法的现象进行了全面、深刻的检讨，从而恢复了这三大方法在人文社会科学研究中的地位，并因此对 2 1世纪的人文社会科学研究产生了深远而积极的影响。

Modern natural science shows that the infancy of life on Earth experienced prebiotic evolution and included the emergence of primitive self-reproducing biologic forms and their systems.
