Though the present switching power supply has been already much lighter and handier than the early linear power supply. But the switching power supply interior still contains a lot of control functions and each control circuit needs some external passive devices, so it still has certain volume and weight. If we combine all the control circuits and the passive devices with whole combo control IC, it will efficiently reduce the volume and weight of the power supply, and the manufacturing cost of the products can be reduced, too.

中文摘要虽然目前的交换式电源供应器已经比早期的线性式电源供应器轻巧许多，但是交换式电源供应器内部仍然含有许多的控制功能，以及各个控制电路所需要的外加被动元件，因此仍具有一定的体积与重量；若是将这些控制电路以及被动元件皆整合成为一个复合式控制晶片，将使得电源供应器的体积与重量能够有效的缩减，同时产品的制造成本也能降低。

After the discourse get rid of the bondage of subject, and when the discourse in face of its own return, it inevitably suffer the threaten of the power. But the microscopic operation way of power causes the power by the creative posture intertwines with discourse mutually. The kind of relation between power and discourse displaying in the literature world represent the literary popular and secularism.

话语在摆脱主体奴役之后，在面向自身回归的过程中不可避免地遭受权力染指其中，而权力的微观运作方式又致使权力以创造性的姿态与话语相互纠结依附在一起，权力和话语的另类关系在文学中表现为文学的大众化和世俗化。
