邓小平对传统开放精神的超越

邓小平以科学的态度批判地继承民族的开放精神,并赋予了新的时代内容:引进资金技术论是对传统"师夷长技"思想的超越;大开放论是对传统社会发展的超越;吸收人类文明成果论是对传统取材异国思想的超越,而基本国策论更是使中华民族的开放精神在新的历史时期得到拓展和升华。     

本科生研究能力阶段性培养思路

在深入分析本科生研究能力存在的问题以及本科生研究能力内涵的基础上,给出相应的本科生研究能力阶段性培养方案,试图通过多种训练方法的有机结合,解决本科生研究能力培养的问题。     

Quantification of microcystin synthetase gene mcyH using real-time quantitative RT-PCR with SYBR green Ⅰ

利用RT-PCR方法从铜绿微囊藻PCC7806 mcy基因中扩增出目的基因片段,用TA克隆方法将基因片段插入pGEMT-T Easy中来制备质粒标准品.通过不同连续稀释倍数的质粒标准品成功构建了16srRNA和mcyH两基因的标准曲线,该法构建的两基因标准曲线r2分别为0.9916和0.9938,且质粒标准品具有较好的重复性,满足实时荧光定量RT-PCR的要求.     

BAN逻辑与串空间的比较

研究了2种安全协议的分析方法,即BAN逻辑和串空间.利用这2种方法分别分析了Needham-Schroeder公钥协议,指出了这2种方法各自的优点和缺点.在对这2种方法进行了比较后,指出了这2种方法有2种结合方式.1种是利用串空间给出BAN逻辑的语义,另外1种结合方式是串行,即对于需要分析的协议,先利用BAN逻辑进行分析,然后再利用串空间进行分析,使分析出的结果更加可靠.     

一类3-紧优双环网无限族

到给定顶点数的双环网的最小直径是图论和计算机工作者广泛研究的问题。虽然大多数双环网可以达到紧优,但仍然有一部分双环网不能达到。本文给出了一类3-紧优的双环网无限族。     

Effects of self evaluation on late ERP components

High-density event-related potentials (ERPs) were measured when participants were required to evaluate oneself, significant others (father and mother) and the most familiar public figures (Lei Feng and Jiang Qing) based on trait adjectives. There were three referential conditions and a non-referential control condition including self-evaluation (SE), significant other-evaluation (SOE), general other-evaluation (GOE), and semantic positivity-evaluation (SPE). The behavioral data showed that RTs to GOE condition were longer than the other three conditions. Scalp ERP analysis revealed that (1) SPE condition elicited a more negative N2 than SE condition, which was associated with inhibition of responses; (2) SE condition elicited a more positive P300 than SPE condition, which was an index of attention to self-relevant stimuli; (3) there was no difference on the amplitude and latency of P300 between SE and SOE conditions, which reflected that the concept of “self” included intimate others (e.g., father and mother) in Chinese culture.     

三维光盘存储系统中双光头同步控制的频域分析与辨识

详细介绍了双光头同步控制原理.对采集的伺服模块聚焦误差跟踪信号及共焦模块读写光头的聚焦线圈驱动信号进行了频域分析,并以此两路信号作为系统输入输出,分别对三种参数模型进行参数优化.根据3种模型的频率响应及阶跃响应,选择双光头同步控制过程的参数模型为[450]阶的ARX模型.实测曲线与模型仿真结果符合度(fit)为78.0259%.
