查询词典 wood range

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。

Principle of least squares,digital image segmentation,digital image treatment and digital image identifying were applied into the research of wood science in this research,the wood cell image of annual ring from annual center to wood edge was analyzed,the modified level set method was applied to segmentate cell image precisely for the first time,the identifying of wood cells and hexagon simulation for wood cells were accomplished with active contour model,which had important potential application value in deepening the research of wood properties to a further step,moreover,had an important significance for improving comprehend on wood micro-properties and enlarging the applicable range of wood.

In first, a new short time formula of one dimension heat conduction differential equation, based on the theory of one dimension transient method, is presented for thermophysical property measurement of wood. The result of testing on red pine and larch wood arc satisfied by new method.In succession, the relationship between heat conductivity of wood and moisture, density, porosity, temperature and grain is studied experimentally in the range from 25 to 100℃. The result shows that, the heat conductivity is in direct proportion to density. but in inverse proportion to porosity. The heat conductivity of air-dried wood increased probably linear with the temperature rising. And that heat conductivity along the grain of wood is higher than that cross the grain. The former is 1.8 or 2 times of the latter.

文中研究了25～100℃范围内，气干木材的导热系数与含水率、密度、孔隙率、温度及热流方向的关系，研究表明：木材导热系数与密度成正比关系，与孔隙率成反比关系：对于针叶材，导热系数与密度及孔隙率成线性变化关系，而对于阔叶材其变化关系近似成二次曲线；气干木材的导热系数随着温度的升高近似呈线性增加：热流平行于纹理方向的导热系数大于垂直于纹理方向的导热系数，两者的比值大约在1.8～2之间。

Wood-plastic composite materials (wood-plasticcomposite, WPC), in recent years developed a new type of material, it will the merits of two different organic materials to combine both surface can be the same as wood glue, paint, or can be nails, drilling, shaver, nails, etc., but also the same as thermoplastic molding plastics processing, played a timber-processing sexual and Plastic Protective Film cessing methods diversity, flexibility, a wide range of application areas.
