摘要
利用刚体转动惯量一般定义形式,经过一系列推导,证明出刚体对任意轴转动惯量定理.由此得到特殊形式的平行轴定理,垂直轴定理及广义垂直轴定理.并通过实例说明此定理在应用上简便。
Alkali and alkali earth metals of 12-tungstoboric acids (salts) were prepared. IR, Uvspectra, XPS and thermal properties were studied and some propenties on salts of inside and outside boundary were also compured.
