First, a specialist in Emergency medical review the 1,281 charts during June 24-July 8, 2004 to decide syndrome group of each patient, and using it as the golden standard. This study collected CC, ICD-9 code, body temperature, and epidemiological data of 126,675 emergency department patients in five hospitals in Taipei during Oct. 1, 2005-Feb. 14, 2007 to set up Poisson regression for counts time series model and use cumulative sum and exponential weighted moving average for alerting. The Poisson regression for counts time series model controlled age, gender, hospitals, Saturday, Sunday, holiday, daily temperature difference, daily lowest temperature, relative humidity and seasonal factors to predict ILI and AGE cases.

Poisson line technique is a method of generating a straight line by diffraction for high precision alignment,which can keep the center of Poisson spot in this line at long distances (several tens or hundreds of meters).

Poisson斑的中心可以在很长的距离内保持与轴心共线因而能实现高精度的对心瞄准，这一技术被称为Poisson线技术。

According to the discussion of the last chapter, we make use of a class of Null Dirac structure on the product Poisson manifold T*M×g* to do the Poisson reduction.

为此，我们利用了T*M×g*上一类Null Dirac结构来做Poisson约化。

The first is that a symplectic structure or a Poisson structure exists on the even dimensional phase space or on the odd dimensional phase space of the corresponding equations. The second is that there is another symplectic structure or another Poisson structure on the generalized phase space which consists of original phase space and independent variable space.

第一、系统在相空间上存在一个一般辛结构或者Poisson结构；第二、系统整体在包括了自变量的增广空间上存在一个一般辛结构或者Poisson结构；第三、第一个结构若是依赖于自变量，那么系统必然受到外力作用（偏微分方程也有特殊的情形，我们在第五章会加以说明），而第二个结构的则给出了第一个结构和外力之间确切的对称关系。

In order to deepen people's comprehension of Poisson Distribution, this thesis adopted examples or proceeded in the form of question, causing people's highly recognition to Poisson distribution.

为加深大家的理解，并以例子或问题的形式进行研究和解答，同时引起大家对Poisson分布的高度重视。

However, for a collection of policies with different quality, it's not suitable to use Poisson distribution to describe its characteristics .

由于Poisson分布在风险理论的研究中具有非常重要的地位，人们通常用它来描述个体保单的索赔次数；但对于非同质或索赔次数不独立的保单组合用Poisson分布来刻画其索赔次数的分布就不合适了。

Then we discusses the Poisson reduction of the submanifold in the product Poisson manifold T*M×g*.

其次，考察在特定的乘积Poisson流形T*M×g*中的子流形的Poisson约化。

For the equivariance of the momentum mapping, we consider the Poisson reduction on some submanifold of the Poisson manifold T*M×g*, and get the reduction phase space.
