objective:to investigate the influence of soybean isoflavones on the antioxidative effect and improving the ability of study and memory in climacteric rats.methods:forty-eight female sd climacteric rats were randomly divided into 4 groups with one control group and the other low,medium and high dose groups,which were given soybean isoflavones 0 mg/kg.bw,42 mg/kg.bw,83 mg/kg.bw and 249 mg/kg.bw by superalimentation daily for 60 days respectively.the levels of sod,gsh-px and mda in serum were measured,and the ability of study and memory in each group was deterimined by adopting the law of diving platform.results:the content of serum mda in medium and high dose groups was lower than that in control group.the activity of serum gsh-px im medium and high dose groups was significantly increased,so was the activity of serum sod in low,medium and high dose groups.conclusion:soybean isoflavones do have the obvious effect of antioxidation,and improve the ability of study and memory effectively in female sd climacteric rats.

目的：观察大豆异黄酮对更年期雌性sd大鼠抗氧化作用及学习记忆的影响。方法：选用健康更年期雌性sd大鼠，随机分成空白对照组和低、中、高剂量4组。空白对照组给予蒸馏水，实验组每日分别灌服42、83、249 mg/kg剂量的大豆异黄酮，连续60d。第60d取血测定血清过氧化脂质丙二醛含量、超氧化物歧化酶活力、谷胱甘肽过氧化物酶活力，用跳台实验方法测定大鼠学习记忆能力。结果：与空白对照组比较，中、高剂量组大鼠血清mda含量显著降低，低、中、高剂量组血清sod活力明显升高，中、高剂量组血清gsh-px活力明显升高。结论：大豆异黄酮具有明显的抗氧化作用，并有效提高更年期雌性sd大鼠的学习记忆能力。

The model is proved by the numerical simulation of three engineering cases. The SMA superelastic damper of tension-pressure type is introduced. The design and the working principle of the damper are outlined.

采用本文的形状记忆合金一维超弹性本构关系模型对工程算例进行了数值模拟，试验和数值模拟结果表明，本文的形状记忆合金超弹性一维本构关系模型，能够比较真实地模拟NiTi形状记忆合金在温度和应力作用下的受力性能，并且形式简单，计算方便，可满足工程应用要求。

RESULTS: Concept, acquire style and characters of memorizing, undermaster the memorizing-like knowledge depends mainly on simple memory,few related to understanding and experiencing, with strong inheriting and depends on the logic , and memorizing was relatively secondary , also with large scale depends on experience as well as the feeling based on experience.

结果：提出了记忆、理解和体验三类知识划分的概念、获取方式和特征。①记忆类知识的掌握主要依赖于单纯的识记，较少涉及理解和经验，具有很强的继承性和传播性。②理解类知识的掌握主要依赖于逻辑，记忆处于相对次要的地位，也具有可继承性和可传播性。

Seeing that the basic researches of the method of metal magnetic memory insufficiently, this text has done the following work mainly:(1)Studied the basic theory of the method of metal magnetic memory;(2)Studied the signal of metal magnetic memory of samples both anneals and not anneals in natural magnetic field and drive magnetic field under the drawn loads;(3) Studied the signal of metal magnetic memory of anneals samples in three magnetic fields under the drawn loads.

鉴于其基础研究工作不足，本文主要做了如下工作：(1)系统地研究了金属磁记忆检测技术的基本理论：(2)研究了退火试件和未退火试件在自然磁场和激励磁场环境中进行拉伸的磁记忆信号；(3)研究了退火试件在三种磁场环境中进行拉伸试验的磁记忆信号。

This research is the first one which discusses "collective memory" under the context of internet. It not only explores how "collective memory" coheres internet community but also talks about the influence of internet upon memory construction.

本研究是国内首篇在网路脉络情境下探讨「集体记忆」概念的学术论文，不仅试图解释「集体记忆」足以凝聚网路社群意识，也尝试讨论网路媒介对於记忆建构的影响。

Methods We designed a kind of radius-ulna shape memory connector on the basis of the shape memory property of nitinol alloy and the anatomic characteristics of radial and ulnar diaphyses.

方法利用镍钛合金的记忆效应和尺、桡骨干的解剖特征，研制具有三维固定作用并能纵向记忆加压于骨断端的尺桡骨形状记忆接骨器。

PartⅡHistidine decarboxylase gene knockout mice potentiates impairment of cued fear extinction induced by morphine withdrawal Previous studies have shown that morphine addiction impairs learning and memory and produces negative emotion.Histamine plays an important modulation on morphine addiction,learning,memory and emotion.

因此，在本研究中我们采用条件性恐惧性记忆和恐惧记忆消除模型，前者是神经生物学上主要研究关联性情绪记忆的模型，后者是人类焦虑性疾病暴露治疗的临床前模型。

These results suggest that morphine withdrawal selectively impairs the cued fear extinction through inhibiting the ERK phosphorylation in the amygdale and mPFC. Histamine deficiency not only enhances acquisition the cued and contextual fear conditioning and but also potentiates the impairment of extinction of cued fear memory.

这些结果提示：吗啡戒断能选择性抑制恐惧记忆的消除，此作用是通过抑制杏仁核和mPFC脑区内ERK蛋白磷酸化来实现的；组胺缺乏能增强线索和背景恐惧记忆的获得以及增强吗啡戒断对线索恐惧记忆消除的抑制作用。
