桤木

Alders, white pine, elm and metasequoia, which were higher

桤木，白松，榆树和水杉，高于接骨木，紫荆

He looked again, straining his keen blue eyes, that had a touch of the Viking in them, through the shadowy pine trees as through a doorway at the green-grassed garden-path rising from the shadow of alders by the log bridge up to the sunlit flowers.

他又看了一遍，瞪圆了他那双锐利的蓝眼睛；他的双眼中透着一股海盗气。穿过仿若门厅的树影翳蔽的松林，他看见了绿草茵茵的花园小路从原木桥边的桤木林掩映处展现，一直通到洒满阳光的花丛那边。

And there stand all around the alders, and birches, and oaks, and maples full of glee and sap, holding in their buds until the waters subside.

那里长满了桤木、桦树、橡树和枫树，生意盎然，一旦大水退去，它们就会爆出新芽。

And headed off up through the alders.

穿过桤木林

Cranberries tossed on the waves and heaving up on the beach, their little red skiffs beating about among the alders;-- such healthy natural tumult as proves the last day is not yet at hand.

酸果蔓在波浪中招摇，红色的小艇摇晃穿梭在桤木丛中-----自然界中这样的小骚动只是一场虚惊，还远非末日来临。

This rise and fall of Walden at long intervals serves this use at least; the water standing at this great height for a year or more, though it makes it difficult to walk round it, kills the shrubs and trees which have sprung up about its edge since the last rise —— pitch pines, birches, alders, aspens, and others —— and,falling again, leaves an unobstructed shore; for, unlike many ponds and all waters which are subject to a daily tide, its shore is cleanest when the water is lowest.

间隔很久的瓦尔登湖的涨落至少有这样一个作用：在最高的水位维持了一年左右，沿湖步行固然困难了，但自从上一次水涨以来，沿湖生长的灌木和苍松，白桦，桤木，白杨等树木都给冲刷掉了，等它水位退下，就留下一片干净的湖岸，它不像别的湖沼和每天水位涨落的河流，它在水位最低时，湖岸上反而最清洁。

Here, ash and linden trees tower nearly 150 feet, their huge canopiesshading a moist, tangled understory of hornbeams, ferns, swamp aldersand crockery-sized fungi.

在这里，高耸的岑树和菩提树差不多长到了150英尺，它们那巨大的林冠荫庇着由角树、蕨类植物、湿地桤木和碗状真菌组成的湿漉漉的地面植被。

It comprises of trans-Himalayan agro-pastoral system of the Dokpas in the alpine plateaus, traditional agroforestry such as alder-cardamom and farm-based systems in the temperate zones, and terraced/valley rice systems in the lower warm temperate to sub-tropical agroclimatic zones.

多样化的农业生态系统，包括位于高山地区农牧复合系统Dokpas，位于温带地区的传统的农林复合系统（如桤木-草本混交农业系统），以及海拔较低的暖温带到亚热带农业气候区的梯田/谷地稻作系统。

The wood properties of alder is similar to that of poplar and birch which could be used to produce different kinds of pulp.The paper is a review about pulp production potential and status of pulping/paper-making and research on wood property of alder in the world.

桤木是一种商用种植较有发展前景的阔叶树种，生长迅速、固氮能力强，木材性质类似于杨木和桦木，可用来开发研制不同的浆种，与针叶木浆或其它阔叶木浆配抄可以生产高质量的印刷纸和书写纸等。

It is shown that it is difficulty to differentiate each vegetation type among sub-tropical evergreen forest, sub-tropical coniferous forest and sub-tropical deciduous forest because of the mixture of their tree spectra. According to the reflection index in the wavelengths of 750 nm to 1 100 nm, the tree species can be divided into 4 groups with descend in reflectivity. Each tree specie can be differentiated from each other according to its slope of the spectrum curve and its reflection index in the wavelengths of 770 nm to 1 010 nm for each forest vegetation type. The unique first order derivative feature can be used to identify litsea, alder, fir, red birch, southwest birch, large schima confertiflora, taiwania flousian and small leaf schima confertiflora.

研究表明：亚热带常绿阔叶林、亚热带针叶林和亚热带落叶阔叶林等植被类型，因其树种间光谱特征混淆严重，而难以彼此区分；根据其反射率在750~1 100 nm范围上的差异，可将其归为4类；就各植被类型而言，其树种间在光谱曲线坡度，以及在770~1 010 nm范围上具有显著差异，可据此将其区分；木姜子、桤木、杉木、红桦、大叶木荷、秃杉和小叶木荷等因具有独特的光谱一阶导数特征，据此可以识别提取。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
