摘要：

The sound velocity v(s)(T) and the electrical resistivity p(T) of La1-xSrXMnO3 (O.11 less than or equal to X less than or equal to 0.17) have been measured and anomalies in v(s)(T), which are related to the polaron-ordered phase centered at X = 1/8, have been observed. The phase diagram between the polaron-ordering temperature T-P and X has been determined from the v(s) anomalies.
