问题描述:
一杯沸水冷却，圆柱体模型，底面半径0.05m，高0.1m，周围温度20度，初始水温100度
方程是四维输运方程（常数a^2=k/(c*p)，k是热传导系数0.6006焦/（米*秒*度））
初始条件：t=0时水等于100度
边界条件：1.上下壁都是自由冷却，第三类边界条件，周围温度保持在20度（H=k/h,h取1）
2.杯壁绝热，第二类边界条件
图形显示格式,取过圆柱轴的截面温度变化将其做成动画.
-Problem description : a cup of boiling water cooling cylinder model, the bottom radius of 0.05m, 0.1m high. temperature around 20 degrees, initial temperature of 100 degrees equation is four-dimensional equations (a constant ^ 2 = k/(c* p), k is the thermal conductivity coefficient of 0.6006 Coke/(m** seconds degrees)) initial conditions : t = 0 to 100 degree water boundary conditions : 1. upper and lower walls are free cooling, the third boundary conditions, maintain the temperature around 20 degrees (H = k/h, h for 1) 2. Beibi insulation, The second category boundary conditions graphics format, cylindrical shaft for the cross section of its temperature changes caused animation.

介绍属性包 IPersistPropertyBag 接口的实现方法和调用方式。属性包，是以“名称 - 值”的方式提供组件持续性的支持，而“名称 - 值”恰恰又适合于用文本方式来表现。下面的片段是在 HTML 中插入 Microsoft MonthView Control ActiveX 控件后的样式：
-briefing packet attributes IPersistPropertyBag interface method and the use of methods. Attribute packets based on the "name-value" component in the form of continuing support, and "name-value" precisely tailored to the text mode is used to show. The following is the HTML fragment inserted Microsoft ActiveX Control MonthView the Styles :
