The framing negotiates still definitely specified, will construct a PI electron product in the HengYang among them capacity fabrication and generalize site.
框架协议还明确规定，其中将在衡阳建设电子产品生产制造及推广基地。
So PI bonds have electron density both above and below the bond axis, but they actually have a nodal plane at this z, this bond axis here.
键在键轴之上，和之下都有电子密度，但它们在z方向有节面，这是键轴的地方。
Square of the Planck constant times pi mass of the electron.
