The eucalypt and its plantation management in Austualia and Brazil were investigated.

考察了澳大利亚和巴西2个国家的桉树，特别是桉树人工林经营状况。

There was no enough evidence to prove the allelopathic effects in eucalypt trees.(4) The effect of eucalypt on ecosystem stability of the soil was caused b

桉树对土壤生态稳定性的影响受客观条件和人为经营共同决定的，桉树本身并不是导致土壤生态稳定性降低的主要原因。

The ability of regeneration was significantly difference between eucalypt species.

桉树更易于在低盐化的土壤上更新，酸化对桉树整体的更新影响不显著。

There are rich resources of natural eucalypt forest in Australia.Brazil is one country with the highest intensive management level of eucalypt plantation in the world.

澳大利亚具有丰富的桉树天然林资源；巴西是世界上桉树人工林集约经营水平最高的国家。

I believe that through the presentations, relevant activities and personal interactions that the conference will lead to a great and positive improvement in eucalypt research and production. I also believe that the conference will help make Zhanjiang world famous and increase social and economic development in Zhanjiang

我相信，通过会议和有关活动，广泛交流世界各地桉树科研和生产的最新成果，对进一步推动湛江桉树科研和生产的发展，提高湛江在国际上的知名度，促进湛江社会经济的发展必将产生重大影响。

This result is provided with the important theoretical and practical significances for the utilization of plantation-grown eucalypt wood as solid wood products.

这一研究结果为桉树用作实木用材产品提供了重要的理论依据。人工林桉树；实木产品；干燥特性；准干燥基准；寺沢真改良百度法

Recognizing the early signs of eucalyptus oil poisoning and allergic reactions to eucalyptus oil is very important.

认识早期迹象桉树油中毒和过敏反应桉树油是非常重要的。

However, there are some censures about the development of Eucalyptus for the incomprehension of the Eucalyptus habitat.

然而，人们对桉树的生境还不甚了解，对发展桉树的认识也存在一些分歧。

Aimed at provide reference and theoretical basis for its scientific management and sustainable development of eucalyptus.

目的在于探讨桉树苗期营养特性及其土壤养分变化规律，为桉树的持续经营和科学管理提供参考依据和理论基础。

We have found that some natural ecosystem services value of Eucalyptus forest is less than that of montane rain forest by 85.82 million Yuan per year. And the decrease value is regarded as a part of natural input. Eucalyptus planting is a kind of mode to use natural resource, it will certainly bring much more economic and social services.

得出桉树人工林在自然生态服务功能方面比山地雨林降低的价值为0.8582亿元/年，我们认为其生态服务功能价值的降低是一种自然投入；发展桉树人工林是人类开发利用自然资源的一种方式，必然会产生强大的经济和社会服务功能。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
