说明：  双容水箱液位控制系统是一种采用先进的控制算法完成对液位的控制的系统, 它在食品加工、原油提炼、化工生产等诸多实用行业中都有广泛使用。本次设计中, 要求设计的超调量小，调节时间短和有自平衡能力等优点。首先要掌握生产工艺和控制流程的基本知识，选择合适的仪表。然后进行系统的设计，明确被控对象，并对系统中每个原件进行模型建立；根据系统要求选择合适的控制方法，对控制器进行参数整定。我们将充分利用计算机技术结合自动控制技术实现对水箱水位的精确控制。(Dual-capacity water tank level control system is a system using advanced control algorithm to complete the control of liquid level, which is widely used in food processing, crude oil refining, chemical production and many other practical industries. In this design, the design requires a small amount of overshoot, short adjustment time and self-balancing ability and other advantages. First of all, we should master the basic knowledge of production process and control process, select the appropriate instrument. Then the system is designed, the controlled objects are identified, and each original in the system is modeled, and the appropriate control method is selected according to the requirements of the system to set the parameters of the controller. We will make full use of computer technology combined with automatic control technology to achieve accurate control of water tank level.)

AS2Debug是为了弥补flash自带的trace的不足而制作的，增加了一下几个主要功能 1.对object和Array做了解析，能输出包含的具体数据和类型 2.对movieclip做了处理，使用digMc方法，可以方便的输出包含的所有子影片的详细信息 3.增加了信息分类和染色(分为trace,info,error,waring四种)(AS2Debug is built-in flash in order to compensate for the lack of trace produced by an increase of about one a few main functions. Array of object and to do the analysis, the output can contain specific data and type 2. Movieclip to do the processing, use digMc methods, the output can easily contain all the details of sub-video 3. an increase of information classification and coloring (divided into trace, info, error, waring four))
