树干

The results show that: Basic density,tracheid length,tracheid width and the ratio of the tracheid length and width increase from core to bark; basic density has a small decrease from base to top,but the change is not significant;The tracheid length,tracheid width and the ratio of the tracheid length and width increase step by .step from the base up to certain height and then decrease by degrees.

基本密度自树干基部向上呈减小趋势，但变化不大；管胞长度、管胞宽度及管胞长宽比自树干基部向上呈&小—大—小&的变异规律；木材的化学成分含量和PH值除抽提物含量随着树高的增加而下降外，其它指标在树高方向上的变化未呈现明显规律性。

The composition and distribution of lichens were influenced by the aspects of the trucks, host trees and their sizes. Richer number and amounts of lichens are found on southern aspect of trunks. Vaccinium duclouxii was the host tree with the richest epiphytic lichens in the forests in the area . Most epiphytic lichens occurred on medium stems of DBH 5.0–25.0 cm.

树干方位、宿主种类和宿主径级等都对附生地衣的物种组成和多样性有着重要影响，附生地衣更多地出现于树干南向方位，云南越桔的附生地衣最为丰富，胸径5.0–25.0 cm 的树木上附生地衣较多。

Wagener, Coder and Mattheck model can be used to effectively assess the hazard of tree trunks, but Mattheck model should be chosen to assess the hazard when the decay or hollow is not located in the centre of tree trunks.

Wagener、Coder和Mattheck模型均可对树干危险性进行有效评价，但当腐朽或空洞区域中心与树干中心不在同一部位时，应采用Mattheck模型对危险性进行评价。

The distribution of soil pH around the boles of spruce and larch growing in liangshui Natural Reserve and Harbin City was studied in order to find out the effect of stem flow on soil pH.

为了解树干径流对林下土壤PH的影响，在凉水自然保护区和哈尔滨市内，取样分析了云杉和落叶松树干周围的土壤pH分布状况。

Determination of Translocation and Distribution of Dichlorvos in Willow Tissue by SFE-GC/MS;2. The translocation,degeneration and residue of chemicals in trees are also discussed.

本文从树干注药的器械和方法、使用的药物种类、药剂在树体内的传导、药剂在植物组织内的代谢和残留等方面，对树干注药技术的研究现状进行了综述。

Any of several Australian eucalypts having the bark smooth except at or near the base of the trunk.

The result indicated that, The small leaf oak bough moisture contentand bough's height above terrain has the remarkable relations, itsmoisture content distribution elevates along with bough's on positionbut gradually rises.

结果表明：小叶青冈树干含水率与树干的离地高度有着显著的关系，其含水率的分布随着树干上的位置升高而逐渐上升。

This article through to the small leaf oak branch moisture contentdetermination and the analysis, take the small leaf oak's bough highlyas an independent variable, take the corresponding high branchmoisture content as the dependent variable,Uses the linear theory to construct the bough moisture contentestimation mathematical model, studies the small leaf oak boughmoisture content the distributed rule.

本文通过对小叶青冈主干含水率的测定和分析，以小叶青冈的树干高度为自变量，以相应高度的主干含水率为因变量，采用线性理论构建树干含水率估测数学模型，研究小叶青冈树干含水率的分布规律。

Trunk not tomentose at apex; bark pale gray, smooth toward base of trunk; mature leaflets glaucous

树干而不是被绒毛的在先端；对于树干的基部浅灰色，平滑的树皮；成熟的小叶有白霜 15 Cycas hongheensis 灰干苏铁

The tree-trunk stands firm and unshakable, but from it und around it it spreads and grows colourfully and multilayered in bulges and crevasses, in lines, structures, forms and colours.

树干深根茁壮、不动摇，不过，树干本身和它的周围的肿块和裂缝中，开始多彩扩张和多层生长，产生线条、结构、造型和色彩。

On closer examination, though, this is not a vote for multilateralism but just the opposite.

仔细审视后我们发现，这并非是对多边主义投出的赞成票，而是恰好相反。
