树干

Spreading short-trunked tree of Japan.

一种日本乔木，树干短小，伸展。

In addition, sunlight is the outcome of coffee growth and indispensable elements, but too strong sunlight will affect the growth of the coffee tree, it usually will work in tandem with various production plant some shade trees, generally more than banana, mango, as well as legumes, such as tree trunks higher plants.

另外，日光虽然是咖啡成长及结果所不可欠缺的要素，但过于强烈的阳光会影响咖啡树的成长，故各个产地通常会配合种植一些遮阳树，一般多种植香蕉、芒果以及豆科植物等树干较高的植物。

Dead branches or knots in different sizes of tree was studied and different branch development phases of growth,suppression,death and self-pruning was analyzed to evaluate the effect that knot size and distribution impact on timber quality.Branch and knot dynamic models were developed using stand and tree variables.Based on multipleunit stepwise regression method, the individual tree growth model was established using forest and crown factors as the variable. The best taper equation model of Larix olgensis was bucking data of 130 sample trees selected in the studied area.

本研究以不同年龄、不同密度及不同立地条件的落叶松人工林作为研究对象，基于19块标准地中95株标准木的树干解析、枝解析及节子剖析数据，揭示了不同林分条件下林木的枝条数量及在树冠内的空间分布格局、生长发育规律；研究了不同大小树木的死枝和节子大小及其变化规律，分析了枝条的生长、被压、寿命和自然整枝过程，评价了节子大小和分布对木材质量的影响；以林分变量、林木变量和着枝深度等为自变量建立枝条生长和节子大小的动态预测模型；选择林分因子和林木的树冠因子作为竞争因子，用多元逐步回归的方法建立落叶松人工林与距离无关的单木生长模型，并根据研究地区选取的130株造材样木数据，建立了落叶松人工林最佳削度方程。

One day while driving along the northern California coast, he found himself gazing at swaths of clear-cuts and spindly second-growth forests.

见2000年10月号、2001年3月号及2001年8月号）一天，当他开车沿加利福尼亚北部海岸行驶时，他不由自主地注意到一长片树干细长的次生林。

Seeing elders with trunks seven feet wide, or walking through stands of the tallest trees here—gigantic Norway spruce, shaggy as Methuselah—should seem as exotic as the Amazon or Antarctica to someone raised among the comparatively puny, second-growth woodlands found throughout the Northern Hemisphere.

看着老树七英尺宽的树干，走在最高的林木之间——巨人般的挪威云杉，它们像玛士撒拉1一样饱经岁月的风霜——对于那些在北半球随处可见、较为低矮的次生林地中长大的人而言，这里本该如同亚马逊流域或南极洲一样让人惊艳。

Give up the flat stream is proud to return to the sea; yellow leaf tree to give up in order to look forward to the verdant spring.

小溪放弃平坦，是为了回归大海的豪迈；黄叶放弃树干，是为了期待春天的葱茏。

The results show that the trend of stem sap flow displays double-peak curve.

结果表明，丝栗栲树干液流速度的昼夜动态表现为双峰曲线。

Populus growth to a high degree of salinity in the soil, due to the Populus cells permeable than the average plant strong, and from the main root and lateral roots, trunk, bark and leaves to be able to absorb a lot of salt, and through the stems and leaves The excretion of salt gland secretion, when the accumulation of too much salt in the body, it can scar from the trunk section of the gap and will be automatically excretion of excess salt out to form a block of white or yellow crystal,"Populus Tears", commonly known as "Populus base."

胡杨能生长在高度盐渍化的土壤上，原因是胡杨的细胞透水性较一般植物强，它从主根、侧根、躯干、树皮到叶片都能吸收很多的盐分，并能通过茎叶的泌腺排泄盐分，当体内盐分积累过多时，它便能从树干的节疤和裂口处将多余的盐分自动排泄出去，形成白色或淡黄色的块状结晶，称&胡杨泪&，俗称&胡杨碱&。

I carefully observed: the first year in the spring, their car from the original habitat has been transported to the area, has been amputation of part of the foliage and roots, the roots wrapped much of the mud on the trunk also used the thick hemp rope ring ring wrapped around on, until the last until canopy.

我仔细观察过：第一年的春季，它们从原生地被车运到此地时，已被砍去枝叶和部分根茎，树根上包着大大的泥块，树干也用了粗大的麻绳一圈圈缠起，直至挨到树冠。

In the shallows, the dark, water-soaked sticks and twigs, smooth and old, were undulating in clusters on the bottom against the clean ribbed sand, and the track of the mussel was plain.

浅水处，黑魆魆的树干和枝梢堆积在湖底透明的沙石上，浸在水里，纹丝不动。蛤贝爬过的轨迹清晰可见。

I am sure after a few weeks of adaptation and familiarization I will have no difficulty in functioning on a daily basis in an English speaking society or in participating fully in graduate studies.

在大学的三年的学习生活不仅给予我自身的充实，更重要的是磨练和培养了我较强的自觉能力和严谨，踏实的作风以及不怕困难的精神，对未来充满了信心！

As the first volcanoes erupted, one of the gases that bellowed out was steam.

在第一批火山喷发时，喷出的气体之一就是水蒸汽。
