摘 要 本文报道了粤东地区野生水果植物资源的调查结果，记录到该地区野生水果植物有57科、101属、205种，分别占全国野生果树73科、173属、1157种的78.1%、58.4%、17.7%，含15种以上的科有蔷薇科、壳斗科、芸香科、桑科4个科，为本地区野生水果的优势科。

Mainly Lauraceae, Fagaceae, Theaceae, magnolia Branch, Division of Hamamelidaceae evergreen broad-leaved trees such as the composition of the shrub layer are found to evergreen species, community structure is more complex.

主要由樟科、壳斗科、山茶科、木兰科、金缕梅科等科的常绿阔叶树组成，灌木层中亦多常绿种类，群落结构比较复杂。

The results showed:(1)The flora of community is rich and complex,and it belongs to the transitional zone for many genera,the subtropical-temperate zone geographical composition of genera are dominant,about 51.47% of the total genera,and there are characteristics which form subtropical to temperate zone transition.(2)The species are mostly composed of Fagaceae,Lauraceae,Anacardiacea...

结果表明(1)该群落区系组成比较丰富和复杂，属于许多属的过渡地带，具有从亚热带向温带过渡的特征；(2)种类组成以壳斗科、樟科、漆树科、卫矛科、榆科、五加科、金缕梅科等为主，但优势种、建群种以温带属为主；(3)种群生活型谱以高位芽占绝对优势，群落垂直结构明显。

Comparative genomics in Salicaceae, Pinaceae, Rosaceae, Fagaceae and Hamamelidaceae had shown that the organization of genomes remained highly conserved over long evolutionary periods and extensive synteny or collinarity or microcollinarity existed in tree genomes.

有关林木比较基因组学研究主要集中在杨柳科、松科、蔷薇科、壳斗科和金缕梅科的一些树种中。

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。
