木材

The result is a wood that retains its shape in the presence of water, and is no longer recognised as wood by grubs that would otherwise attack it.

其结果是木材在保持水分的情况下形状不变。而且也不被咬食它的蛴螬认作木材。

By analyzing these data,it was concluded that:1The combustion of wood,including rate of heat release,total heat release,effective heat of combustion,mass loss rate,smoke ratio,specific extinction area,concentration of CO_2 and the yield of CO_2Y_(CO2,were decreased considerably by the treatment of FRW;2There is a strong synergistic effect of fire retardance between GUP and boric acid;3The trend of MLR curve of FZ was similar to its RHR curve,weight loss and heat release were happened mainly in flaming phase;4Char formation of wood was markedly accelerated by FRW,which indicated that catalytic charring effect of FRW on wood is the primary side in its fire-retardation mechanism.

对于组成和结构变异性很大的木材而言，由于CONE实验所使用的样品量相对于其他分析方法要大得多，因而实验结果比较有代表性。此外，CONE实验可在模拟火灾条件下进行，这是该方法的又一突出的优点[5～6]。木材阻燃剂FRW主要由磷酸脒基脲和硼酸组成，此外还含有

The caloric values and ash contents of some mangrove woods in Dongzhai Harbor Mangrove Forest Reserve of Hainan Province were determined in Summer,and the changes of the caloric value of Kandelia candel woods at different latitudes were studied.

在夏季对海南东寨港红树林自然保护区一些红树植物木材的灰分含量和热值进行了测定，并研究了夏季不同纬度的秋茄木材热值的变化。

One of the most common ways to describe a wood's tonal properties is in terms of its frequency range,which is often broken down into low-end frequencies,mid-range and high-end frequencies.picture it as a visual spectrum,as we've done in the chart to the right,with the lower frequencies on the left and the higher frequen-cies on the right.the graph line for each wood visually depicts its general tonal range.rosewood and ovang kol,for example,tend to resonate with more low-end frequencies,whereas koa,cocobolo and maple tend to sound brighter from having more top-end frequencies.note also rosewood's"scooped"midrange and ovang-kol's fuller midrange.the doted lines for walnut and koa denote the expansion of low-end frequency range as the guitar opens up after a period of playing it.

最常见的方式描述了木材的声音特性是在其频率范围内，这往往是细分为低端频率，中端和高端frequencies.picture它作为一个视觉频谱，因为我们'维生素E这样做的图表，以权，以较低的频率在左边和更高的频率，种上right.the图线的每一个木材视觉描绘的一般音调range.rosewood和ovang科尔举例来说，往往会产生共鸣更多的低端频率，而兴亚， cocobolo和枫树往往从健全光明有更多的高端frequencies.note也花梨木的&收购&的中端和ovang -科尔的充分midrange.the doted线的核桃和兴亚指扩大低端频率范围内的吉他开辟了一段时间后，打它。

Results showed the lignin degrading ability of 6 species of wood white rot fungi is different, it is Pycnoporus sanguineus, Pseudotrametes gibbbosa, Polyporellus brumalis, Lenzites tricolor, Funalia gallica and Phellius igniarius in turn.

结果表明，这6种木材白腐菌对山杨木材木质素的分解能力不同，依次为血红密孔菌、偏肿拟栓菌、冬拟多孔菌、三色革裥菌、粗毛盖菌和火木层孔菌。

Taking Taiwania cryptomerioides as an example, as estimation, the preservation treated sill of one wooden construction building with a floor area of 136 m2 could reduce 43.72 kg CO2 which fixed in the wood would return to the atmosphere by the gnawing of termite. And it would reduce 129.90 kg and 123.50 kg of CO2 caused by the infringement of Lenzites betulina and Laetiporus sulphureus respectively.

CO2减量效益方面，建筑物若加以适当的木材防腐后，以台湾杉试材经AAC防腐，所改善的试材重量损失率为例，一栋面积为136 m2木质构造建筑物之地槛材部分，可减少因台湾家白蚁啃蚀造成木材中固定的CO2约43.72 kg返还大气；抵抗白腐菌及褐腐菌侵害而言，减少129.90及123.50 kg的CO2返还大气。

The invention relates to a method for stocking and preserving green round wood and sawn timber, which is stored in an airtight and lighttight sealing cover. The oxygen inside the cover is decomposed by the respiratory process of mushrooms, bacteria and wood cells that are still alive, thereby forming CO2 and H2O.

本发明涉及用来保存绿圆木或锯成木材的方法，其中将绿圆木或锯成木材储存在不透气和不透光的包覆层下面，所述包覆层以内的氧气被真菌和细菌的呼吸和发酵过程以及仍然存活的木细胞的呼吸过程所消化，因此产生CO2、H2O。

Moreover, taking the adsorption process from oven-dry state to the equilibrium state in 20℃,60%RH environment as an example, the dielectric relaxation based on the reorientation of adsorbed water molecules was separated out from that based on the methylol groups in the amorphous region of wood cell wall.

以绝干状态→20℃，60%RH 平衡态的吸湿过程为例，将基于吸着水分子回转取向运动的介电弛豫与基于木材无定形区中伯醇羟基回转取向运动的介电弛豫进行分离，并在 Eyring 的绝对速度反应论的基础上，求得了与吸着水分子进行回转取向运动相关连的热力学量，得到了在吸着过程中吸着水分子与木材吸着点之间的氢键结合随着水分吸着进程的变化情况。

In this paper, a controlled-atmosphere cone calorimeter was used to investigate the smoking property of wood treated with fire-retardant monoammonium phosphate and the untreated for comparison.

在相同的氧浓度下，当氧浓度在16％以上时，MAP阻燃木材燃烧过程中的浓烟释放（RSR、TSR和SEA）小于素材；而当氧浓度在16％以下时，MAP阻燃木材燃烧过程中的浓烟释放（RSR、TSR和SEA）反而高于素材。

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。
