La 3Ga 5SiO 14的结构类似于石英，预期其具有良好的传播特性。数值分析了瑞利波在La_3Ga_5SiO_（14）衬底上的传播特性，并与石英衬底上的传播特性进行了比较。在La 3Ga 5SiO 14上的相速度通常比石英上的相速度慢约70%。La_3Ga_5SiO_（14）的K_2比石英的K_2大2-3倍。的传播特性的比较是基于几个材料常数，迄今已报道。延迟温度系数（TCD）显示出相对较大的差异。
La3Ga5SiO14 is structurally similar to quartz, and its good propagation characteristics are expected. A numerical analysis of the propagation characteristics of a Rayleigh wave on La3Ga5SiO14 is presented in comparison with those on quartz. The phase velocity on La3Ga5SiO14 is generally about 70% slower than that on quartz. The K2 of La3Ga5SiO14 is about 2–3 times larger than that of quartz. A comparison of the propagation characteristics is made based on several material constants which have been reported so far. The temperature coefficient of delay (TCD) shows a relatively high difference.
