压电常数
Based on the Newnham series and parallel theory of composites, deduced the calculation formulae of dielectric and piezoelectric constant of 1-3-2 type piezoelectric composite.
基于Newnham复合材料串、并联理论,推导了计算1-3-2型压电复合材料的介电常数和压电常数的公式。
The effective piezoelectric constant of ZnO nanowires is found to increase with increasing diameter, but the values are much smaller than that of bulk ZnO, at least in the limited size studied in the present calculations.
研究发现,ZnO纳米线的等效压电系数随着直径的增加而增大,但至少在本文计算能力所能达到的范围内数值上要远低于相应的体块值。
