The legislative also in this case being supposed to consist of several persons,(for if it be a single person, it cannot but be always in being, and so will, as supreme, naturally have the supreme executive power, together with the legislative) may assemble, and exercise their legislature, at the times that either their original constitution, or their own adjournment, appoints, or when they please; if neither of these hath appointed any time, or there be no other way prescribed to convoke them: for the supreme power being placed in them by the people, it is always in them, and they may exercise it when they please, unless by their original constitution they are limited to certain seasons, or by an act of their supreme power they have adjourned to a certain time; and when that time comes, they have a right to assemble and act again.

在这种情况下，立法权力还应当被假定包括若干人，（因为如果是一个人，它就不能总是单独存在，随之而来的，自然的会将立法权力和最高执行权力都攫取在一个人手中）在最初的宪法所规定的时间，或他们休会时所指定的时间，或在任何他们想集会的时间——如果前两者都没有确定时间，或没有规定其它的召集办法的话——集会，行使他们的立法权力：因为立法权力既已交给他们，他们就可以在他们想行使的时候行使，除非根据最初的宪法他们只能在一定的时期内行使，或者根据最高权力的法案他们需要休会一定的时间；休会结束时，他们又拥有权利可以集会和制定法案了。

Owing to its small volume, light weight, high efficiency, succinct circuitry, high reliability and great capability of self-equalizing output loads in different circuitries, the Fly-back Converter becomes the optimally topological form of designing auxiliary power supply of high frequency switching power and driving power supply of power switching.

By adding an equivalent harmonic impedance in the branch circuit of power grid, this HAPF could force all the harmonic currents flow into passive power filters, which resulting in eliminating harmonic contamination more effective. And using the capacitive feature of PPF in the fundamental frequency, this HAPF could compensate fixed-capacity reactive power without increasing APF's burden. Moreover, in order to decrease APF's cost, the fundamental voltage will largely be endured by capacitor in view of the series resonance circuit tuned at the fundamental frequency, so the APF just bears little harmonic voltages.

其基本工作原理是：有源部分等效于在电网支路中串联了一个谐波阻抗，该谐波阻抗对基波电流不起作用，而对谐波电流产生很大阻碍作用，迫使谐波电流流入无源滤波器，从而达到滤除谐波的目的；同时新型注入式混合有源滤波器还充分利用了无源滤波器的无功补偿功能，在不增加有源部分容量的前提下，可以提供一定容量的无功功率；由于有源部分承受的电网基波电压不大，也没有基波电流流入，因此逆变器容量小，初期投资较小。

The silicon solar modules produced by our company may fall into two kinds, that is, large power modules (ranging from 10wp-165wp) and small power modules (ranging form 0.1wp-10wp). The former mainly uses reinforced glass and aluminum alloy rim. It ischaracterized by large power, high conversion efficiency and long service life. It is widely used in the off-grid solar system,on-gridsolar system, household generating and lighting system, traffic lights and solar lighting lamps; the latter chooses quality importedmonocrystalline or polycrystalline silicon solar chips, using solar resin gum for sealing and PET lamination or glass lamination sealing.It is characterized by portability, flexibility, beautiful appearance, and excellent performance. It is mainly applied to solar lawn lamps,portable power solar handicrafts, electric toys and other small electronic and electrical appliances.

It comes to the conclusion that in Chinese comprehensive universities, the marginal contribution of the academic power is larger than the administrative power, that is, the expansion of academic power will play a more notable role than the expansion of the administrative power.

上述研究显示出，大学权力结构中行政权力与学术权力相对大小的不同将对大学的组织效率产生不同的影响；当前我国教学科研型大学中，学术权力的边际贡献比行政权力的贡献大，即扩大学术权力的作用要比扩大行政权力的作用大。

If the legislative, or any part of it, be made up of representatives chosen for that time by the people, which afterwards return into the ordinary state of subjects, and have no share in the legislature but upon a new choice, this power of chusing must also be exercised by the people, either at certain appointed seasons, or else when they are summoned to it; and in this latter case the power of convoking the legislative is ordinarily placed in the executive, and has one of these two limitations in respect of time: that either the original constitution requires their assembling and acting at certain intervals, and then the executive power does nothing but ministerially issue directions for their electing and assembling, according to due forms; or else it is left to his prudence to call them by new elections, when the occasions or exigencies of the public require the amendment of old, or making of new laws, or the redress or prevention of any inconveniencies, that lie on, or threaten the people.

如果立法权力或它的任何部分，由人们选举的代表组成，在需要立法的时候集会，法律制定之后仍回归臣民的普通状态，除非重新当选，不再享有任何立法权力，那么选举的权力也应由人们在一确定的时间或当他们被召集时行使；在后一种情况下，召集立法的权力通常交给执行权力，在时间上受以下二者限制：或由最初的宪法规定的每隔一段时间之后就集会并制定法律，执行权力仅仅以政府的名义发布依据正当的形式进行议员选举和集会的指令；或当公共领域出现紧急情况，要求修订旧法律，或制定新法律，或矫正和预防任何存在和将威胁人们的不便干扰，这留给执行权力的审慎来决定，通过新的选举来召集立法议员。
