After I referred tos correlative books which write about the progress of the environmental scenes design, and summarized correlative theories, such as the design concepts of chinese classical garden,the Garden-aesthetics,the Forest-esthetics,the forest culture theory,the Landscape-designs studying, the Landscape Ecology,the Environmental capacity studying etc…On this base,I brought forward some related principle and notion in the construction technology and research some main items should pay attention to in the construction technology about Forest Home environmental scene.

在参考当前相关领域的研究进展并在结合中国古典园林设计理论、园林美学、森林美学、森林文化理论、景观设计学、环境容量学等相关理论的基础上，提出了森林人家环境景观营建的原则和指导思想，总结出森林人家环境景观营建需注意的主要事项。

The main topics of this course include forest trees seeds, silviculture and forest protection.

森林学2主要课程内容包括林木种子学，育林学及森林保护学。

This is the website of the Oxford Forestry Institute, which fully incorporated into the Department of Plant Sciences for some reason recently. It is devoted to forestry research in the areas of ecology, silviculture, sustainable management and biodiversity.

这是牛津林业科学研究所的网站，该所是于近期与牛津大学植物科学系合并的，专注于生态学、森林学、森林的可持续管理和生物多样性等方面的林业科学研究。

Forestry appertains to geography , to botany, and to agriculture

森林学与地理学、植物学和农学有关。

Forestry appertains to geography.

森林学和地理学有关。

Many complicated phenomena existing in the fields of system forestry and system forest have been analyzed Especially from the view of modern forestry and non-linear dynamics, the dynamical mechanism that complicated phenomena could be produced has concisely been discussed And further their research methods that should be intercrossed with modern non-linear science are discussed All these should be of importance for constructing and perfecting the subjects of modern forest engineering

特别从现代林业工程系统和非线性动力学的角度，简要分析了复杂现象出现的内在动力学机理，并在研究方法上就如何和现代非线性科学结合，作了一些讨论，对于在系统林学、系统森林学的基础上，建设现代林业工程学具有一定的意义。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
