        <p>忽然觉得可能多数人看到这个界面会一脸懵，所以我还是写个说明吧。</p>
        <p>上下两个面板都可以用文字直接输入化学式，上面那个负责运算，下面那个负责数据库的交互。</p>
        <p>具体怎么操作相信大家都能看懂，用最右边的箭头可以切换功能，然后输入化学式，按下按钮，或者回车也行。至于相对质量，由于不需要多少算力，它是实时更新的。</p>
        <p>我运用了聪明绝顶的正则表达式（也就是那一串火星文），保证了查询方程式时，只要所有分子完全匹配，无论顺序都能查得到。你也可以改为只查包含某种元素的化学式，按左边的按钮就行。</p>
        <p>左边的箭头按钮考虑的是在上下之间快速复制粘贴方程式，不过这个功能还没完全实现。以及根据描述查询方程式的功能也还没实现。</p>
        <p>我目前只录入了高一上学期讲的一些式子，你要是吃饱了闲着没事干也可以帮我录入。查到的方程式带着的数字就是它的 id，修改的时候用得到。</p>
