钛酸锶（STO）和铝酸镧（LAO）杨氏模量和泊松比是多少？ 钛酸锶（STO）300Gpa 0.23 来源Microstructure and Properties of High-Temperature Superconductorsp588 http：//books.google.com.hk/books？id=NQdHAAAAQBAJ&pg=PA589&lpg=PA589&dq=srtio3+toughness&source=bl&ots=QLJP2F5HE8&sig=XV2uxxUAHbRJn7ImjPKecVve4HA&hl=zh-CN&sa=X&ei=Un2pUsfsK-KAiQfzjIGQCg&ved=0CHIQ6AEwCQ#v=onepage&q=srtio3%20toughness&f=false不过我没细看，你要看下是单晶的还是多晶，还是薄膜
压电陶瓷用的什么材料，杨氏模量和泊松系数
