On the basis of formal chapters' analysis, learning from foreign countries' successful experience in circular economy's legislation, considering our own legislation practice in developing circular economy, the main framework of our country's circular economy's legal institutions' construction is put forward as follows, the guidance thought of the circular economy's legal institutions' construction is the concept of scientific development and the thought of sustainable development; the 3R principle, the principle of following the ecological rules, the principle of giving priority to precautions, the principle of the contaminator paying are the basic principles of the circular economy's legal institutions' construction; the field of the natural resources' exploitation and utilization, the field of manufacturing industry and service trades, the field of disposing waste and changing waste into resources, the field of the exploiting and utilizing energy, and the field of social consumption are the key fields of the circular economy's legal institution's construction; the circular economy's legal system is constructed from four levels, the basic laws, the principle laws, the comprehensive laws and the special laws; The following circular economy's legal institutions are made, the institution of circular economy's planning, the institution of green economy's accounting, the institution of scientific and technological information's titles, the institution of economic encouragement, the institution of market allowance, the institution of listing the names' who set good example in developing circular economy, the institution of forcing those enterprises with heavy pollution into developing circular economy, the institution of green consumption, the institution of the public's participation, the institution of sharing the responsibility, and the institution of evaluating the circular economy's results.

After take analyzed deeply for the opened magnet circuit with FEMM (Finite Element Method Magnetics) we find out the field distributing that is separated into three sections . One is the main area what we called as positive field section. Beside the main field there are tow areas that are called the inverted field sections. Loudspeaker arise a very serious distortion when the voice coil moving into inverted field areas. The direction of induced current in the coil part of entered inverted field area is same with the current driving into loudspeaker so that total currents increas largely and heat increase rapidly. With more coils moving into inverted area the voice coil will take on negative inductance properties. It is the main reason that voice coil is burned by heating with increasing current due to arise negative inductance. So opened magnetic circuit is not suitable for the woofers in which the voice coil have wider displacement range. When using this kind magnetic circuit design, the voice coil moving range should be less than the range of positive field to avoid loudspeaker arise serious distortion and heating. Even though voice coil moving range is in the positive area, loudspeaker will still arise more distortion because the field distribution is very cliffy at tow sides of the positive area and full range of magnetic field distribution is not parallel that will arise distortion. Base on above reasons, opened magnetic circuit is not an ideal magnetic circuit for low-frequency loudspeakers. But it can be used in mid-range or high-frequency productions.

开式磁路是由2片钕铁硼磁铁和主导磁板和导磁垫片组成，我们在实践过程中发现这种磁路结构不适合于低频扬声器的使用，我们通过使用FEMM（Finite Element Method Magnetics）软件包对该磁路进行了分析，该磁路的磁场范围被分成3个区域，其中在主导磁板附近形成一个正向磁场，在正向磁场的两边存在反向的磁场，音圈在工作时有很大一部分进入了反向磁场中，在反向磁场内线圈的感应电流方向与驱动电流方向相同，使得音圈呈现出负感抗特性，由于音圈的负感抗特性引起电流的增加导致音圈发热甚至烧毁，因此在扬声器中使用开式磁路时，音圈的运动范围应控制在正向磁场范围之内，否则音圈运动到反向磁场区域时将会产生很大的失真和发热，即使在设计时已经将音圈的运动范围控制在正向磁场范围之内，由于正向磁场的2个边缘磁场强度衰减太快，同时开式磁路中磁场的分布不是平行的，而是自由发散的分布，这样肯定会导致扬声器的非线性失真，因此我们得到的结论是：开式磁路并不是一个理想的磁路，它不适合于低频扬声器的使用，但它还可以应用于中高频扬声器。
