Mr Rossi, Dr. the Flinders University ofSouth Australia, calculated electron collision with molecule, but theexchange term he used become bigger and bigger as incident energyincreases, it is unreasonable, besides, the potential of electron and nucleus heused is somewhat rough. At present we correct these two terms. The potentialconsists of static potential, exchange potential, polarization potential.

For example of atom of hydrogen, it must be enough surrounding electrons so can be form a "electron space", it could be form gravitation among electron and proton, at first whole gravitation line may acts with proton ,but if the quantity of electron go to much ,every one can got gravitation line from proton would be lower, the gravitation between proton and electron would be drop, when it is reached fixed lever, this power is equal to expulsive force which between electrons , so it would be reach balance, the electron can't much more.

之间形成引力，质子向外发出的引力线本来可以全部同外围电子作用，但是，电子多了，每一枚电子从质子分到的作用引力线便减少，它们同质子间的引力要下降，下降到一定程度，此力等于电子间的斥力，达到平衡，电子便不能再多。

The five prosthetic groups (FAD, [2Fe-2S], [4Fe-4S], [3Fe-4S] and heme group) required for electron transfer from succinate to ubiquinone were unambiguously assigned into the electron density map. Besides, we find there are some electron densities around the Qp pocket at the matrix side and we believe it represents the head structure of ubiquinone, which is proved by the inhibitor bound structure that 2-TTFA just locating at the Qp site. At the same time, we find there is the second 2-TTFA binding site, locating the inter-membrane side. This finding will change our knowledge about the electron transfer inside Complex II and the ubiquinone transfer between Complex II and Complex III, and endow a new role of Complex II in electron transfer chain.
