Example Sentences:

	1.	This paper is taking model seismology theory as guidance , regards ultrasonic experimental method as major research means , and has made artificial crack and pore model according to physical model similar principle with various materials 本文以模型地震学理论为指导，把超声波实验方法作为主要的研究手段，根据物理模型相似性原理，用多种材料制作了人工裂缝模型和孔洞模型。
	2.	Along with increase of pressure , the parameters such as velocity , amplitude , main frequency and quality factor of seismic wave change big gradually , while change very weakly with the change of temperature . through testing research for artificial crack and pore model , we conclude that crack density , azimuth , opening and the change of pore have obvious influences on speed , amplitude , attenuation ( or quality factor ) and main frequency of seismic wave etc . but , seismic wave dynamic characteristics are more evident than its kinematical characteristics for the change of crack and pore parameters . therefore , it offers reliable experiment foundation for detecting crack and pore by seismic wave kinematical characteristics ( such as amplitude , attenuation and main frequency etc . ) 通过对人工裂缝和孔洞模型的超声波实验研究，可以认为：裂缝密度、方位、张开度和孔洞密度的变化对纵横波的速度、振幅、衰减(或品质因子q )和主频率等参数均有明显的影响，但裂隙参数的变化对地震波动力学特征参数(振幅、衰减、主频率等)的影响远远大于对运动学特征参数(速度等)的影响，这为利用地震波的振幅、衰减和主频率等属性参数进行裂缝和孔洞特征的检测提供了可靠的实验基础。
	3.	5 experimental study about the influence that is resulted from the artificial crack flaw on the propagation of longitudinal stress wave in pipeline has been done . experimental result make us know that the signal collected can reflect the defect " s influence which will provide the important basic for the next analysis in this paper 5 、利用实验研究了人工裂纹缺陷对管道中波传播特性的影响，通过对比，用实验证实了这种影响确实存在，为本文进一步对缺陷的识别和定位提供了重要的基础。
