In this paprer, the usual notions of superlinearity and sublinearity for Biharmonic problems $\Delta^2 u + c\Delta u =f $ are given a local form and extended to infinite nonlinearities.

在本文中,我们给出了双调和超线性和次线性问题$\Delta^2 u + c\Delta u =f $的一个局部形式且扩展为不定的非线性形式。

The project will develop a bandpass sigma-delta analog-to-digital converter for digital audio broadcasting system in three years. In the first year, we had finished the system simulation for IF receiver using conventional high speed ADC and bandpass sigma-delta ADC, respectively. We also had done the analysis and design of high-order bandpass sigma-delta modulator structure. In this year, we have developed a coefficient synthesis method for high order bandpass sigma-delta modulator using high order filter transfer functions (inverse Chebyshev bandreject filter function).

本计划将在三年内发展一个能应用在数位音讯广播系统的带通sigma-delta类比/数位转换器(analog-to-digital converter,ADC),在第一年度中我们分别以传统高速类比/数位转换器及带通SD类比/数位转换器的接收系统为例,并结合编码正交多工器(Coded Orthogonal Frequency Division Multiplex,COFDM)的技术,建立一套DAB系统模拟的方法,同时并研究有关高阶带通SD类比/数位调变器的架构及电路,并已成功开发出一个由高阶滤波器合成的高阶带通调变器。

Institute of Statistics and Actuary, Shandong Economic UniversityAbstract We consider the risk process perturbed by diffusion under interest force in this article. The integral expressions, continuities, twice continuous differentiability and integro-differential equations about $F_{\delta}$, the distribution of the surplus immediately before ruin, and $H_{\delta}$, the joint distribution of the surplus immediately before ruin and the deficit at ruin are obtained.

我们考虑既带有随机干扰又带有确定投资回报的风险过程,得到了破产前瞬间盈余的分布$F_{\delta}$及破产前瞬间盈余和破产时赤字的联合分布$H_{\delta}$所满足的积分表达,连续性及二次连续可微性和积分--微分方程。

The affected chicks acquired the morphine conditioned place preference more quickly, and maintained it much longer. Experiment 3 showed that during E5-8, injecting delta receptor antagonist naltrindole reversed the learning and memory impairment caused by morphine while delta receptor agonist DPDPE impaired learning and partial memory function. On the other hand, mu opioid receptors had little effect. As for E17-20, given naloxonazine can reverse the increases of susceptibility to morphine, and the mu receptor agonist DAGO cause the increases of susceptibility to morphine. Delta receptors have no effect.

研究结果发现:经过对鸡胚发育不同时间段的吗啡给药,胚胎期发育E5-8阶段给予吗啡的小鸡学习记忆受损最为严重,表现为学习和记忆功能的严重下降;而E17-20时段吗啡给药的小鸡更容易获得吗啡CPP且保持时间更长。E5-8阶段给予delta受体拮抗剂natrindole能够翻转吗啡对学习和记忆的损害作用,并且给予delta受体激动剂DPDPE也损害学习和部分记忆功能,mu受体作用不大。E17-20阶段拮抗mu受体能够抑制成瘾易感性的增加,激动mu受体可以增加小鸡的成瘾易感性,delta受体没有明显作用。

In the context of signal processing it is often referred to as the unit impulse function. Note that the Dirac delta is not strictly a function. While for many purposes it can be manipulated as such, formally it can be defined as a distribution that is also a measure .

在物理上,通常用于代表脉冲函数,或者呈点分布的物理量,例如质点、点电荷等;另外,delta函数常用于表示对物理量在某点的抽样,这一点不仅在数学物理方法这样的理论学科中常用,在实际的工程通信中也很常用,这时delta函数被用作采样函数。

By the delta matrix inverse lemma, the delta operator recursive least squares algorithm is derived, and convergence about DRLS is also proved.

基于Delta算子矩阵求逆引理,导出Delta算子最小二乘估计的递推算法,证明了DRLS的收敛性。

Besides neurokinins, recently we found that the dominant opioid receptor, delta subtype, was existed in renal pelvis and intrapelvic activation of DOR resulted dose-dependent increases in ANRA, suggested that DOR plays a role in regulating renal sensory response.

除了神经激肽受体之外,本实验室最近也发现类鸦片受体在肾盂表现并且其中以delta亚型的类鸦片受体(delta-opioid receptor, DOR)为主,活化肾盂内DOR可够剂量依存性地增加传入性肾神经的活性,所以DOR可调控肾脏感觉功能。
