linear conditions meaning in Chinese

线性条件
线性状态

After the nonlinear and absorption effect is taken into account in the applications where high power ultrasonic is involved , the first and second harmonic components of the sound field of stepped circular plate is analyzed , based on the kzk equation and quasi - linear condition
考虑到大功率超声应用中的非线性和吸收作用，本文从kzk方程和准线性条件出发，对于工作在共振频率下的这种阶梯圆盘，推导了它的一阶和二阶谐波声场计算方法。
Taking the transfer of energies between harmonics into account under the quasilinear approximation , the temperature distributions in tissues during ultrasound heating at various transducer parameters and tissue properties are investigated , and the results are compared with that obtained for linear conditions
摘要在准线性条件下，计及谐波间能量转移，分析了超声热疗换能器及组织特性参数对组织内温度场的影响，并与线性条件下的结果进行了比较。
