So to heighten the theoretical level of controls, we have to apply some control methods which realize the stabilization of the inverted pendulum by dint of our strength.The paper is based on the double linear inverted pendulum model, after concisely introducing the development and current situation of inverted pendulum system research, the mechanism and mathematical model of inverted pendulum are presented,mathematical model of the double inverted pendulum is particularly educed.

近年来，许多学者已经应用各种各样的控制方法对倒立摆系统进行广泛地研究，尽管国内外对倒立摆的研究已有显著成果，但作者对倒立摆的研究才刚刚起步，需要在学习和总结已有经验的基础上，研究倒立摆的控制，以提高控制理论的水平。

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。

The opened magnetic circuit is composed as tow NdFeB permanent magnets and a top plate without U-yoke.

Controlling an inverted pendulum is one of the classic problems in the field of control theory research. The self-balancing vehicle introduced in this article is a new style of inverted pendulum; we call it "mobile inverted pendulum".

摘要倒立摆的控制是控制理论研究中的一个经典问题，本文介绍的自平衡电动车就是一种新式的倒立摆，我们称它为移动式的倒立摆。

Mainly consists of two aspects, one is made from an inverted pendulum control of the initial perspective through direct adaptive fuzzy control methods to restore stability at Liandugu; the other is an inverted pendulum control from the initial point begun tracking a sine curve, Even inverted pendulum angle according to the requirements of the sinusoidal changes.

主要分两个方面，一方面是使倒立摆从一个可控制的初始角度开始通过直接自适应模糊控制的方法使其重新稳定在零度角；另一方面是使倒立摆从一个可控制的初始角度开始使其跟踪一个正弦曲线，即使倒立摆的角度按所要求的正弦变化。

By comparing different processes in the same period, following operting modeof interactive reactor was recommend: enhanced A~2/O process fits on spring period,pre-anoxic inverted A~2/O process was recommend in dry/mizzle weather in summerperiod, step aeration process was adopted in rainy weather in summer period,alternating oxygen concentration inverted A~2/O process was appropriate in autumnperiod, and normal inverted A~2/O process was better in winter period.

With a background of heated gold investment, most new passionate investors came into the market without simply understanding the gold investment. This made many investors lost their capital when first stepped into the market. In addition, many gold exchange types are specialized in enlarging guarantee sum. Compared with investment in stock market, investors who invested in types characterized in enlarging guarantee sum would likely to face more risks and challenges. Those risks could enlarge investors' one-year loss in stock market to one-day loss in gold market. Nowadays, Chinese gold market can be differentiated into material gold market, paper gold market, in-stock gold and future gold market. Because of the enlarging system in international gold market, investors may lose to the bottom in one day if he or she chose a guarantee sum dealer with an highly enlarging system. Of course, this is an ultimate example. In gold market, the type with the least risk is material gold, such as gold memorative silver coin, material piece of gold and gold brick. Material gold investment enjoyed its popularity among middle or large cities located in the middle and eastern part of China.

在黄金投资火热的背后，是大部分新入市投资者盲目的热情，由于对黄金投资缺乏了解，很多投资者入市即被套，而且很多黄金交易品种具备保证金放大效应，和在股市投资相比，投资者炒作保证金放大品种进行投资，往往需要面对高额风险，这种风险可以使投资者在股市中一年时间遭受的损失在一天内就提现出来，现在国内黄金市场主要分为实物黄金市场、纸黄金市场、黄金现货、黄金期货市场，其中国际黄金现货市场由于存在高度放大机制，如果投资者选择具备高度放大的保证金交易商，经常会出现一天内就会血本无归的情况，当然，这是极端的情况，黄金市场中，风险最小的是实物黄金，例如黄金纪念金银币、实物金条、金砖，实物黄金投资在中东部地区大中城市比较流行。
