text="1926年1—6月,他一连发表了四篇论文,题目都是《量子化就是本征值问题》,系统地阐明了波动力学理论。在此以前,德国物理学家W.K.海森堡、M.玻恩和E.P.约旦于1925年7—9月通过另一途径建立了矩阵力学。1926年3月,薛定谔发现波动力学和矩阵力学在数学上是等价的,是量子力学的两种形式,可以通过数学变换,从一个理论转到另一个理论。薛定谔起初试图把波函数解释为三维空间中的振动,把振幅解释为电荷密度,把粒子解释为波包。但他无法解决“波包扩散”的困难。最后物理学界普遍接受了玻恩提出的波函数的几率解释。"
lessHeight={72}
showMoreText="... 展示更多"
showMoreElement={
<span>
... <span className="show-more-text">展示更多</span>
</span>
}
showLessElement={<span className="show-more-text">收起</span>}
onClick={() => {
this.setState({ collapsed: !collapsed });
}}
/>
);
}
}
If you like to prevent collapse on user select, add this before setting collapsed
.
const selection = window.getSelection();
if (!selection.toString()) {
/* Set `collapsed` prop */
}
