The paper carries out mechanical analysis of the weight distributing of goods in loading container based on analysis of packing and tansporting environment, and draws the formula of the ratio of the weight of loading goods and the maximum loading weight W/W0, and the length distributing ratio of loading goods α=l/L under the condition that the bending quadrature produced by part load is within the range of the maximum bending quadrature. It also gives the graph that the sum deflection of mudsill and underside girder can reach high-point value with the length of bottom distributing varying, when the loading amounts of container of 20ft and 40ft are given. Furthermore, it provides the relation graph of an eccentric rate of loading goods and the allowed loading amount. For on-site safety loading work, it has certain guidance and reference value.

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。

loading coil:加感线圈
当一固定长度的天线使用加感线圈(loading coil)它的虚形的理论长度会向下延伸,比肉眼看到的实际长度还长,若是在天线上加幅射状的棒棒或圈圈那叫top loading,它会使虚形的理论天线向上延伸.
