first resonance是什么意思

网络释义

用法例句

When the quality and stiffness of outshoot are far larger than those of the main body, and k1/k2 approaches M1/M2, second-order resonance vibration happens.

当主体结构的刚度k1远远大于突出物的刚度k2,主体结构的质量M1远远大于突出物的质量M2,且k1／k2与M1／M2相接近时,容易发生二次共振。

The energy-iteration method for strongly non-linear autonomous system was modified to deal with strongly non-linear non-autonomous system, and the modified new method was developed, the analytic expressions of solution of primary resonance and superharmonic and subharmonic resonance.

研究了在横向动载荷作用下存在轴向力的一类梁的强非线性振动;建立了梁振动的二阶强非线性非自治微分方程,并对求解强非线性自治系统的能量迭代法加以改进,用于求解梁的强非线性非自治系统,其方法是:由能量法得到主共振、超谐共振和次谐共振的一次近似解的表达式;引入牛顿迭代的思想和最小二乘法,得到高次近似解的表达式。

Based on the condition, the stability boundaries are obtained in the cases of subharmonic resonance and conbination resonance.

利用该条件得到了次谐共振和组合共振的稳定边界。

The spin resonance peaks will beabsorbed into uniform resonance peaks as the exchange coupling field becomes larger,and the perpendicu-lar uniform resonance linewidth ΔH also can be characterized linearly by the exchange coupling,till thespin resonance peaks disappear and ΔH becomes the largest.

交换耦合作用场增大,自旋波共振模式向一致共振峰模式退化,而一致共振线宽与交换耦合场存在着线性关系,直至自旋共振峰消失,而一致共振线宽达最大值。
