" There is no critical boundary between speculation and investment, especially when all participators are immersed in delighted atmosphere, There is nothing so easier than large amount of unearned money that can lead person to loss the logos. Even more normal person will lose his head, after such kind of experience mentioned. The more time they stay in the dancing party, that is invest much capital into the speculative operation, the larger the proportion of The Pumpkin carriage and mouse driver show the hoof is. All of them intend to stay to the last minute rather than miss any minute of the dancing party. But the point is there is no pointer in the clock at all." Buffett wrote these words to shareholders in 2000 years.

"股神"巴菲特2000年写给股东的信中写道："投资与投机之间永远是一线之隔，尤其是当所有市场的参与者都沉浸在欢愉的气氛当中时更是如此，再也没有比大笔不劳而获的金钱更让人失去理性，在经历过这类经验之后，再正常的人也会像参加舞会的灰姑娘一样被冲昏了头，他们明知在舞会中多待一会-也就是继续将大笔的资金投入到投机的活动之上，南瓜马车与老鼠驾驶现出原形的机率就越高，但他们还是舍不得错过这场盛大舞会的任何一分钟，所有人都打算继续待到最后一刻才离开，但问题是这场舞会中的时钟根本就没有指针！"

Firstly, the three-dimension boundary question and its corresponding variation question concerning the point-source electrical field on a 3-D structure are presented. Secondly, the finite element method is used to solve the variational equation. The study area is divided into many tetrahedral elements. Then, we interpolate with a tri-linear function in each element. So, the variational equation is converted into a linear equation system. Finally, taking into account saving of time, we make use of symmetric successive overrelaxation preconditioned conjugate gradient algorithm to solve large linear system, and obtain the potential value of each node, resulting in the calculation of the apparent resistivity values on the ground surface.
