木材

Although a modern instrument in every sense of the word, it employs almost exclusively the time-honoured materials of metal and wood in its construction.

虽然这是一件十足的现代乐器，它的材料却是历来极受珍视的各种金属和木材；金属方面以锡和铜为主，而不同的组件则以各式木材来制造。

A simulated burnt piece of coal or wood, usually a plastic casing having a wood-like or coal-like coating, with a light source mounted therein, and a strip of cloth having a shape of fire flames billowed above the simulated burning medium by blowing wind. A vision of jiggling fire flame may be viewed through a partially translucent screen made of plastic.

现有的电壁炉火焰模拟装置中，一类装置为模拟煤炭或树枝状碳块的燃烧介质，通常这些燃烧介质由表面涂有树枝状木材颜色的塑料壳体替代，里面装有一组灯泡光源，来模拟燃烧树枝状木材时的效果，再用一组火焰形状的丝绸布料飘带悬挂在燃烧介质上方，通过空气的吹动来带动飘带飘动时的投影效果，通过半透明的塑料屏幕与镜面玻璃，可以看到火焰闪动的视觉景象。

The physical and mechanical properties of the hybrid tulip tree are firstly reported and analyzed in this paper.

摘 要：本文研究了杂种鹅掌楸木材的物理力学性质，并与其母本中国鹅掌楸和父本北美鹅掌楸木材的作了比较。

Wood used for building timber, light construction, carpentry, joinery, shingles, woodware, turnery, furniture, veneer, boats, wood based material, plywood.

木材用于建筑木材，轻型建筑，木工，细木工，带状疱疹，木制品，车削，家具，胶合板，船，木质材料，胶合板。

How to establish creep model of under change loads are unfathomed contents in theory studies and applications of wood rheology.

如何建立木材在变载荷下蠕变的数学模型，是木材流变学在理论研究和生产应用中迄今尚未解决的问题。

Some wood snobs say that unfigured snakewood is useless but they are very wrong --- it is a very hard, dense, wood that turns VERY nicely and polishes to a VERY high gloss and does not suffer from the brittleness of the figured sections.

一些木材snobs说， unfigured snakewood是无用的，但他们是非常错误的---这是一个非常艰苦，致密，木材，把391和打磨，以非常高的光泽度，不遭受的脆性在占有部分。

It may reduce the temperature in cities, shorten the tart-up frequency and the operating time of fridges and air-conditioner, diminish the transformation of electric energy to thermal energy and cut down sunlight heat's sucking the vapory if we create more green areas and increase the deposit of timber so as to store carbon dioxide in it.

分析了植树造林有助于缓解气候变暖的原理，包括扩大绿色覆盖面积，增加木材蓄积量，将二氧化碳贮存于木材之中；增加绿色覆盖面积，可以降低城市气温，减少电冰箱、空调开启次数和运行时间，减少电能向热能的转化；降低太阳光、热对地气的抽吸作用。

The veneer is coated with chitosan after dyed considering that the color fastness to water is bad after wood veneer dyed by acid dyes and it is easy to fade.

木材染色的实质是染料分子在木材中的渗透和固着过程，而这两个过程是相互矛盾的，往往渗透性好的染料其抗流失性差[1]。

In order to study the effects of acid catalysts on wood liquefaction in phenol, the liquefaction of wood powder from Chinese fir and poplar in the presence of phenol using several relatively weak acids as catalysts, such as phosphoric acid (85%), sulfuric acid (36%), hydrochloric acid (37%) and oxalic acid (99%), were investigated.

为了探讨酸性催化剂对木材苯酚液化的影响，该研究采用磷酸(85%)、低浓硫酸(36%)、盐酸(37%)、草酸(99.5%)4种弱酸性无机酸，在不同温度下进行了木材的液化试验。

The optimum condition of PWF prepared fromliquefied wood is: actual pH of liquefied wood without extra acid, 105℃, 150min and 0.7～0.8of ratio of formaldehyde to phenol.

木材液化产物制备PWF的适宜工艺参数为：pH为木材液化产物的实际值，温度105℃，时间150min，n∶n=0.7～0.8。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
