There are those who seem to think that by force of will they can coerce this law; that they can sow seed of one kind and by "Will Power" make it bear fruit of another, but the fundamental principle of creative power is in the Universal, and therefore the idea of forcing a compliance with our wishes by the power of the individual will is an inverted conception which may appear to succeed for a while but is eventually doomed to failure - because it antagonizes the very power which it is seeking to use.

有些人可能以为通过意志的强制性作用可以迫使这个法则进行改变。通过&意志力&，他们能够&种瓜得豆&。然而，创造力的基本原理是普遍存在的。因此，想要通过个人意志的力量使宇宙力量依从我们的愿望是一种歪曲的理念，这种理念可能会获得一时的成功，但终究会落得个铩羽而归的下场──因为这种想法与它所寻求的宇宙力量存在著冲突。

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。
