查询词典 Poisson summation formula

According to that characteristic and based on the differential equation of the deformed surface of the orthotropic plate, with one principal direction size fixed, changing another principal direction size linearly, maintaining elasticity coefficient the same as in the first principal direction and Poisson ratio equal to the geometric mean of two principal Poisson ratios, the original orthogonal plate is equivalent to an isotropic plate. Results obtained show that the deflections of the equivalent isotropic plate are the same as the deflections of the original orthotropic plate at the corresponding points, the forces of the correspondent points have simple relations.

根据这一特性、从正交各向异性板挠曲面的偏微分方程出发，保持一个主方向尺寸不变，另一主方向的尺寸做线性缩放，保持弹性模量与第一主方向相同，泊松比取2个主方向泊松比的几何平均值，将这类正交各向异性板等效为一块各向同性板；通过分析得到：各向同性板任意点的挠度就是原正交各向异性板对应点的挠度，各对应点内力之间存在简单的比例关系，该文的方法将为工程技术人员提供方便，同时可以更加直观的认识正交各向异性板的受力。

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.

做法上，由专科医师回顾台北市某医院2004年一周共1，281 笔的急诊病患资料进行症候群分类，建立症候群的黄金标准；并收集台北市五家医院2005年10月1日至2007年2月14日共126，675 位急诊病人之主诉症状、ICD-9 码、体温及流行病学相关资料，进行症候群侦测数据分析，以建立波以松时间序列分析预测模式(Poisson regression for counts time series)，且控制重要因子(性别、年龄、医院别、周六、周日及假日效应、日温差、每日最低温、相对湿度及季节)，进行流感及急性肠胃炎个案数之预测。

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。

Given a mesh, we first solve a Poisson equation to construct a scalar field and use it to generate some critical points. The cutting paths between the critical points and the boundaries are solved in the Poisson scalar field using the deepest descent method. For meshes with nonzero-genus, we construct a Harmonic scalar field, and connect the saddle points with the boundaries based on the Morse theory.

对于给定的任意网格，通过求解泊松方程构造标量场来选取临界点，并采用最速下降法给出临界点到边界或者初始点的切割路径；对于亏格不为零的网格，基于Morse理论，通过构造一个调和标量场来得到鞍点，并将它们连接到边界。

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。

On the other hand, many important risk processes are also special cases of Levy processes, such as Brownian motion, the compound Poisson process, the compound Poisson process perturbed by Brownian motion.

另一方面，风险理论中的许多风险模型，如经典风险模型，带干扰的经典风险模型，布朗运动等，均是一些特殊的Levy过程。

The witness also told the jury at the Royal Courts of Justice in London that he saw a paparazzo fighting with a member of the public who was trying to stop him taking pictures in the minutes before the emergency services arrived.

他还告诉在伦敦皇家法庭的陪审团，在急救服务到来之前，他当时看见一个狗仔队正和一群阻止他拍照的人打架。
