With the development of modern molecular biology technique and metagenomics, it provide new research method and opportunity for uncultured microorganism in the environment.

Totally, these results indicated that tailing pile could be the new source for finding new heavy-metal-tolerant microorganisms. Two morphologically distinct types of colonies investigated in this study may include more than 4 undescribed bacterial species.

同时还初步发现几个有进化生态学意义的现象：(1)矿渣极强的重金属选择作用和环境隔离条件可能导致新物种在短期内形成；(2)自然选择可能在物种以上层次发挥作用；(3)不同环境因子对微生物生物量、抗性细菌比例、物种和遗传多样性等生物指征的作用不同；(4)不同的生物特征对环境因子修饰作用的敏感程度也不一样。

And in the aspect of ecocritical exploration, we can feel that the poets pursue unfailingly the correspondence of natural imagery with the human being, and pay a great attention to unhuman forms of lives and the substantial environment. And the author also considers that such Eastern idea as oneness of Heaven and Man doubtlessly plays an important role for some poets to form their ecological concept of nature.

在生态学意义的探究方面，认为从中西诗歌中，我们可以感知，诗人一直在不倦地追求自然意象与人类灵魂的契合，以及对非人类的生命形式和物质环境的关注，而且认为东方的天人合一、物我合一等思想无疑对一些诗人的自然观念的形成起了重要作用。

We discussed the stability of the system balance, used the Poincare-Bendixson's annular region theorem to prove the existence, and used the Zhang Zhifen unicity theorem to prove the uniqueness of limit cycle, at the same time give meaning to the corresponding conclusions on the ecology.

讨论了系统平衡点的稳定性，用Bendixson环域定理证明极限环的存在性，借助张芷芬唯一性定理证明极限环的唯一性，同时对相应结论的生态学意义给予说明。

On the existing city to resolve this problem is unrealistic, from the point of view of ecology is also unscientific.

依靠现有城市来解决这一问题是不现实的，从生态学的角度讲也是不科学的。

Charles Robert Darwin is not only an extremely important thinker in the history of evolution thoughts but also a famous urger before the ecology revolutionary.

According to a study by psychologist Eric Bressler of Westfield State College in Massachusetts and Signal Balshine, an associate professor of behavioral ecology and evolution at McMaster University in Ontario, both men and women were attracted to people with a sense of humor.

美国马萨诸塞州威斯尔德州立学院的心理学家Eric Bressler和加拿大安大略省麦克马斯特大学的行为生态学和进化学副教授Signal Balshine在研究中发现，无论男女都会被具有幽默感的人所吸引。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
