线热膨胀系数 coefficient of linear thermal expansion
- 研究结果表明,纳米晶体线越细,其热膨胀系数越大。
The results show that the thinner crystal nano-wire has a larger thermal expansion coefficient. - 依据这种电子结构计算了晶格常数、结合能、势能曲线、体弹性模量和线热膨胀系数随温度的变化,理论值与实验值均符合较好。
According to this electronic structure, lattice constant, cohesive energy, potential curve, bulk modulus and temperature dependence of linear thermal expansion coefficient have been calculated.
