颗粒复合材料 meaning in English
particulate composite
Examples
- The average thermal intensity inside the particle is obtained based on the solution of the temperature field inside the particle . the effective thermal conductivities for composites with different particulate geometry are calculated by using the prediction formula
在求解颗粒复合材料不同形状夹杂内温度场的基础上，进而求解其夹杂相的平均温度梯度，利用有效热导率的预测公式，对含不同形状夹杂的复合材料进行数值计算从而得到其有效热导率。 - The study results display : the particle shape trends to needle more , the effective permittivity is bigger when the volume of particle is the same . the particle shape trends to penny more , the effective permittivity is bigger when the volume of particle is the same . the dimension of particle does n ' t affect the effective permittivity when the shape of particle is equal
本文的研究结果表明，对于无壳颗粒复合材料在相同的体积情况下，粒子的形状越是趋于针形，等效介电常数越大；粒子形状越是趋于便士形，等效介电常数越大；比较而言，便士形的等效介电常数大于针形的介电常数，而以球形的介电常数最小。 - On condition that the volume of particle is equal , the effective permittivity of penny shape particle is the biggest , that of the needle shape is second , and the spherical shape is the last . when the thicker of shell is constant and the radius of core is bigger , the effective permittivity is less . the effective permittivity will change acutely when the thicker of shell is close to the radius of core ; with the radius of core increasing , the effective permittivity of core - shell type particle will approach that of no shell type particle
在相同的形状下(如便士形和针形) ，粒子的大小对于等效介电常数没有影响；对于核壳形夹杂颗粒复合材料，当壳的厚度一定时，随着核的半径的增大，复合材料的等效介电常数越来越小；当壳的厚度和核的半径较接近的时候，复合材料的等效介电常数将会发生急剧的变化；随着核的半径的不断增大，核壳型颗粒夹杂复合材料的等效介电常数将逐渐的趋近于没有壳的夹杂颗粒复合材料的等效介电常数。
