查询词典 change-over

Apparently, the giant panda's evolution from Ursus to Ailuropoda required the change of only a few genetic messages (5 or 6 perhaps), yet the phenotypic and lifestyle change from a standard bear is considerable. The transition could therefore be effected relatively swiftly.

显然，从熊到大熊猫的进化只需要少数遗传信息（也许5或6个遗传信息）的改变；然而，在表型和生活方式上与一头标准熊相比，发生了相当大的改变；而且这种转变过渡可能是相对迅速地达到的。

Under the different pH conditions, the migration and transformation behavior of each form of phosphorus released from the lake sediments into water body was studied by means of simulation. The results show that under alkalic condition or acidic condition, the temporal and spatial distribution of phosphorus in the water body changes with its releasing mechanism, and its migration and transformation behaviors are various. The change of pH value has no obvious effect on such transformation, but the total phosphorus in the water body has substantial effect on the concentration change of various forms of phosphorus.

通过室内模拟湖泊沉积物在不同pH条件下，研究释放到水体中各种磷形态的迁移转化行为，结果表明：碱性条件和酸性条件下，水体磷的时空变化由于其释放机制的不同，其迁移转化行为各不相同，同时，pH值的变化对水体中各种磷的相互转化没有明显的作用，各种磷形态的浓度变化，在很大程度上取决于水体中总磷的浓度。
