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。

论文以解决陕北地区的收入问题,植被问题以及粮食产量问题为出发点,首先从理论上分析了包络分析方法在陕北地区退耕还林中运用的可行性,然后结合陕北地区目前的实际情况,综合分析出影响陕北地区退耕还林的关键的七个因素作为输入指标:水利水保设施投入,农作物投入,经济林种支出,防护林支出,其它经济作物,草类支出,畜牧业投入;以退耕还林所要解决的最终问题作为输出指标:GDP收入、农民人均纯收入、水土流失减少量、牧业总产值、粮食产量、林业总产值、其他经济作物总产值。将各指标所对应的数据代入模型后,通过分析求解得出非有效的决策单元,再运用包络分析方法的一些基本原理对非有效的决策单元进行调整,由此所得的数据对陕北地区的实际投入具有很好的指导意义。同时,又针对陕北地区在退耕还林过程中以及之后可能面临的困境,提出了一些建议和对策。最终使得陕北地区的投资环境尽快得以改善,使农民尽快脱贫致富,使人口、资源、环境的关系尽快纳入良性循环的轨道上。

Dye can bring a little color to life, most clothing is color with dyes, modern manufacture dyes can be costly, natural dyes from plan t and animal products have been used since ancient times, so this week, we describe by natural way to dye world, the advice comes from information written by Jenny Tim of the intermedial technology development group in Briton, this anti group is now called practical action, there are several messages to put dye onto material, the vent message for example, can be used to dye wool with onion skins, for this example, use 100 grams of natural wool, the wool must be clean, leave it overnight in water and liquid soap, then wash it with clean water that is a little warm, gently out the water, a solution called a moderant is used in the dying process, a moderant helps fix the dye to the material, traditionally moderants were found in nature, wood ash is one of example, but chemical moderants such as ironare popular today, iron is so would in many stores, it is often mixed with queen of daughter, a finding powder commonly used in cooking.
使用染料可以为生活带来更多的色彩。许多的布料都是通过染料来上色的。现代工业制造的染料通常都非常的贵,从古时起,人们就知道从植物或者动物产品中提取天然染料。这周,我们就来讨论一下如何用天然的方法来给羊毛着色。这一建议来自英国中级技术发展组的Jenny Dean的信息。这一古老贫穷的小组现在被称为实用性活动。把染料加到材料上有几种方法。其中之一是大桶法。举例来说,就是用洋葱皮来染羊毛。这一例子中,用100g的天然羊毛。羊毛必须清洗。用液体肥皂浸泡过夜。然后用温的干净的水冲洗它。轻柔地把多余的水分压挤出来。一种叫做媒染的溶剂也用于染洗过程。媒染是用来固定染料和材料的。传统的方法是,媒染是来天然的,比如木灰。但是像明矾这样的化学媒染在今天也是很流行的。明矾在许多商场都有出售。它通常和一种经常被用于烹调的粉状物-酒石混在一起。我们用多一点点的辛苦,来交换多一点点的幸福

These Thoughts so oppress'd my Mind, that I began to give over my Enterprize, and having haled my Boat into a little Creek on the Shore, I stept out, and sat me down upon a little rising bit of Ground, very pensive and anxious, between Fear and Desire about my Voyage; when as I was musing, I could perceive that the Tide was turn'd, and the Flood come on, upon which my going was for so many Hours impracticable; upon this presently it occurr'd to me, that I should go up to the highest Piece of Ground I could find, and observe, if I could, how the Sets of the Tide, or Currents lay, when the Flood came in, that I might judge whether if I was driven one way out, I might not expect to be driven another way home, with the same Rapidness of the Currents: This Thought was no sooner in my Head, but I cast my Eye upon a little Hill, which sufficiently over-look'd the Sea both ways, and from whence I had a clear view of the Currents, or Sets of the Tide, and which way I was to guide my self in my Return; here I found, that as the Current of the Ebb set out close by the South Point of the Island; so the Current of the Flood set in close by the Shore of the North Side, and that I had nothing to do but to keep to the North of the Island in my Return, and I should do well enough.
我思想压力很大,不得不考虑放弃原定的计划。我把小船拉进沿岸的一条小河里,自己迈步上岸,在一块小小的高地上坐下来沉思。我心情忧郁,心绪不宁。我害怕死,又想前去探个究竟。正当我沉思默想之际,只见潮流起了变化,潮水开始上涨。这样,我一时肯定走不成了。这时,我忽然想到,应该找一个最高的地方,上去观察一下潮水上涨时那两股急流的流向,从中我可以作出判断,万一我被一股急流冲入大海,是否有可能被另一股急流冲回来。我刚想到这一层,就看见附近有一座小山;从山上可以看到左右两边的海面,并对两股急流的流向可以一目了然,从而可以确定我回来时应走哪一个方向。到了山上,我发现那退潮的急流是沿着小岛的南部往外流的,而那涨潮的急流是沿着小岛的北部往里流的。这样,我回来时,小舟只要沿着北部行驶,自然就可以被涨潮的急流带回来。
