A new method for determination of elastic and anelastic parameters of solids is now available. The method called the resonant sphere technique (RST) has been much advanced by this research project for three years, especially in(1) The RST becomes applicable from isotropic to orthorhombic materials,(2) High temperature measurement is possible up to 1300K, and probably much higher, and(3) High pressure measurement is possible up to 100MPa (1kbar), and pressure derivatives of elasticity are obtained.Application of the RST has been made for variety of Earth's materials. Elasticity and internal friction of the specimens are measured at the ambient condition and/or at high temperatures. We find systematics between elasticity and density, and also between internal friction and velocity. These relationships seem useful in comparison of the seismic earth models with petrological ones.We have also tried the FT method to obtain spectrum from wave form data in time-domain. This method is expected to be potential in spectral analysis in future.

现在已有一种测定固体弹性和滞弹性参数的新方法。三年来，该研究项目大大推进了称为谐振球技术（Resonant sphere technique，简称谐振球技术）的方法，特别是（1）谐振球技术适用于从各向同性到正交材料，（2）高温测量可以达到1300 K，甚至更高，（3）高压测量可以达到100 MPa（1 kbar）。并对各种地球材料进行了应用。在环境条件下和/或在高温下测量试样的弹性和内摩擦。我们发现弹性和密度之间，以及内部摩擦和速度之间存在系统性。这些关系在地震地球模型与岩石学地球模型的比较中似乎是有用的。我们还尝试了FT方法从时域波形数据中获得频谱。该方法在光谱分析中有着广阔的应用前景。
