双语例句
- The change of film thickness can result in the changes of specific surface area, orientation distribution ratio, internal stress distribution, transition phase volume fraction, crystal defect concentration and planar defect density.
薄膜厚度变化引起比表面积、位向分布比例、内应力分布、过渡相数量、点缺陷和面缺陷浓度的变化。 - Numerical experiments predicted average diameter, overall surface area, volume fraction and number density for the soot particles, and growth rate of naphthaline ( A4) and acetylene ( C2H2) on particle surface.
通过数值计算预报了碳黑颗粒平均粒径、总表面积、体积分数和数密度，以及萘（A4）和乙炔（C2H2）在颗粒表面的增长速率。 - It was shown by the results that porosity, pore volume, specific surface area of coal in outburst zone increased with the increase of its carbon atom mole fraction, and the above mentioned parameters were related to the position of coal sampled.
结果表明，突出区煤的孔隙率、孔容、比表面积等均随其碳原子摩尔分数Xc的增大而增大，且上述参数均与煤样点的位置有关； - So some surface area of the particles can be eliminated and the specific surface and the activity of the particles decreased, the mass fraction of zirconium tungstate decreased with the ball milling time increasing.
这样便消除了晶粒部分表面，使缺陷得到调整，应力得到缓和，最后导致比表面积下降，活性也降低，所以ZrW2O8的质量分数随球磨时间的增加而减少。
