Cyanobacteria and other microorganisms build stromatolites in shallow water as they grow, gradually trapping and binding sediments into the small rock-like towers and mounds.
当浅水区的蓝细菌和其它微生物生长的时候，一些沉积物沉积在上面，它们结合在一起形成岩石一样的小石塔和石丘，最后逐渐形成层状叠层石。
The results show that the binding energies of shallow donor impurity states strongly depend not only on the wire radius, but also on the applied electric field and the impurity position in the wire.
结果表明杂质态结合能不只是量子线半径的函数，它还随杂质位置，外电场强度发生变化。
