Fall suppose in Swerling Ⅱ target, derivation detect below environment of ADT of threshold value of the MGF of quadrature generation function that this algorithm issues in even setting, average judgment, much target the maths of aiguille of the false alarm in probability Pd and clutter brim environment is analytic expression.

在SwerlingⅡ型目标假设下,推导了该算法在均匀背景下的矩产生函数MGF、平均判决阈值ADT、多目标环境下检测概率Pd和杂波边缘环境中虚警尖峰的数学解析表达式。

However,in at early work of Dolan and Jackiw, after the analytic continuation ofthe imaginary time thermal propagator, the result was not the 2 × 2 matrix thermalpropagator in the real time formalisms, but only the 1-1 component of the matrix,which caused singularities like higher order δ function's.

然而在Dolan和Jackiw的工作中,由虚时热传播子解析延拓得到的结果不是实时方法中的二阶矩阵形式的热传播子,而只是其中的1-1矩阵元,从而会导致象高阶δ函数这样的奇异性,本文指出,这个结果是来源于一个隐含的假设,即认为实时方法的背景时空是一个明氏时空。

Under Swerling Ⅱ assumption, the analytic expression of P in homogeneous background is derived.

在SwerlingⅡ型目标假设下,推导出ACCAGO-CFAR在均匀背景下虚警概率P的解析表达式。

We use the data from BHP company in 1995-2001 and calculate the implied volatility. By comparing the implied volatility calculated from actual option price and the assumed volatility in the model, it is found that Black-Scholes Model does underprice the Out-of-The-Money options and overprice the In-The-Money options because of the wrong assumption on the volatility.

本文选择了澳大利亚BHP公司1995年-2001年其中五年的数据,从实际期权价格中计算得到隐含波动率,并把其与Black-Scholes模型中的假设波动率进行比较,最后可以发现,Black-Scholes模型低估了虚值期权的价格,高估了实值期权的价格,与一般的研究结果恰好相反。

The theory is based on the laws of thermodynamics and the pseudo elastic postulate.

理论的基础是热力学定律及虚弹性假设。

Based on the variational principle of virtual voltage and virtual displacement derived in this thesis and the classical theory of linear laminated plates, and by using the constitutive equations of elastic piezoelectric materials, and the DKQ quadrilateral plate bending element, the finite element modeling for the fabric reinforced laminated plates with nonlinear voltage-electric strain relationship of piezoelectric actuators has been established for the first time in this thesis. And the expressions for the electric loadings with obvious mechanical meaning and convenient for computation are established, which can be used to the deformation analysis of laminated plates with piezoelectric actuators under specified voltages.

以本文直接导出的压电结构的虚电势—虚位移变分原理为基础,依据经典线性层合板理论和压电弹性体的本构方程,采用基于离散法线假设的DKQ四结点任意四边形薄板弯曲单元,首次建立了考虑非线性电压—电应变关系的含压电致动器的纤维增强型层合板的有限元分析模型,并推导建立了力学意义明确、便于计算的电荷载表达式,可用于指定电压条件下纤维增强型叠层合成板的变形分析。

When parameters satisfy some assumptions, Rossler system is a chaotic dynamical system. In order to discuss the dynamical character of Rossler system and use delayed feedback control chaos, in the first, we discuss the stability of the steady states of Rossler system with delayed feedback. When the engenvalues of the linear part are pure imaginary numbers, we obtain the corresponding delay value. The stability of the steady state is lost when the delay passes through the critical value, and simultaneity chaos may vanish, as well as there will be a family periodic solutions bifurcate from the steady states.

在几个参数满足一定的假设条件下,Rossler系统是一个具有混沌特性的动力系统,为了研究该系统的动力学性质并利用时滞实现混沌控制,本文首先对具有时滞的Rossler系统的平衡点进行稳定性分析,当系统的线性部分对应的特征值为纯虚根时,算出相应的时滞τ,得到了平衡点的稳定性会在时滞τ取某些值时发生翻转,同时系统的混沌特性也会出现变化,并且在平衡点处系统经历Hopf分支。

Based on the hypothesis of Brands, this thesis presents two off-line electronic cash system applied to small payment: one is an off-line nondivisible electronic cash system with complete anonymity, and the other is an off-line nondivisible electronic cashsystem with repealed anonymity. The two systems can solve the bottleneck problem of bank server. Furthermore, based on the concept of virtual debit as well as the payment demand of pay-per-use electronic commerce and mobile commerce, this paper designs a micro-system NPAY, which can solve the problem of extra-consuming, greatly reduce the system communication overhead, and the consumer can anonymously consume.

Null hypothesis:虚假设

在统计学术语中,这个抽样可变性说明被称为虚假设(null hypothesis). (虚假设由符号 Ho 表示)在本例中,用公式将它表示成这样的语句:在作出回答的所有类别中,各种回答的期望数目相同. Ho:# Keiths = # Olands = # Schooner = # Other如果您能够排除虚假设,

null function:零函数

null ellipse 零椭圆 | null function 零函数 | null hypothesis 虚假设

virtual displacement:虚位移

只因在力学的虚功原理[ ] 中, 虚位移(virtual displacement) 确是假设的, 或称假想的. 所以日本人在很早以前就把虚功 (virtual work) 译为 "假想仕事", 虚位移则译 "假想变位". 这个 "假想" 本来只用于虚功原理. 可是,

tachyons:超光子

1967 年,物理学家范伯 格(Gerald Feinberg)提出了理论上存在超光速粒子的假设,他更将它命名为超光 子(tachyons). 它的性质当然是稀奇古怪,例如:它的质量是个虚 数(不是负数,而是某负数的平方根 );当它损失能量时速度增加,
