This process varies with the site and circumstances, but in its archetypical form fast-growing annual weeds cover the soil first, playing the role of what ecologists classify as pioneer plants.

这一过程的长短因不同的地点和环境而异。起初，生长迅速的年生草先把土壤覆盖住，起到一种生态学家称之为&先驱植物&的作用。

Niche which many ecologists have become interested in is an important concept in ecology. The main definitions of niche are the habitat niche of Grinnell (1917), the functional niche of Elton (1933) and the hypervolume niche of Hutchinson (1957) whose concept has by far the largest influence on niche.

生态位是生态学的一个重要概念，许多生态学家都对生态位下了定义，主要有Grinnell(1917)的生境生态位，Elton(1933)的功能生态位，Hutchinson(1957)的超体积生态位，尤以Hutchinson的&超体积生态位&影响为大。

I leave the low, katabatic valleys to the regional planners and ecologists, since they insist on staying in those dammed-up areas, and I propose that the one good thing Olmsted said was "aptness"– things should be apt, appropriate…………..

至於那些低洼阴湿的谷地，就留给区域规划师与生态学家了；是他们自己执意要待在那堤堰围绕的低下地方的。

生态学家们估算着相互竞争的生物的竞争力，为水和日照的权利而斗争。

The West orientalized the Noble Savages of the Americas, Africa, and the Pacific first as the enemy, brutal, warlike, and dull. Now the same lens on the Noble Savages puts in view an exotic remnant of a romantic past and reveals them to be generous, peaceful, dignified, and wise ecologists.

美洲、非洲、太平洋地区那些西方被东方化了的&高贵蛮族&最开始被看作是敌人、粗鲁残忍的、好战的、以及阴暗的；现在对'高贵蛮族'的观点则被看作是他们具有传奇而浪漫的过去，他们是慷慨大方的、和平的、并且是睿智的生态主义者。

Based on SIMPLER algorithm in the curvilinear body-fitted coordinates, the calculations were performed for Pr=0.7, Re=10~1000 on non-orthogonal non-staggered grids which are generated by elliptic equation systems.

采用曲线坐标系下压力与速度耦合的SIMPLER算法，数值研究了周期性渐扩渐缩波纹通道内脉动流动与换热情况，流动Re数的范围为10~1000，Pr数为0.7。
