 [PDF]

Advances in Psychology (AP) , 2014, DOI: 10.12677/AP.2014.42042
Abstract: 情绪智力对个体情绪调节起着重要的作用。采用情绪智力测评量表(EIS)测量370名大学生的情绪智力,从中随机抽取得分较高和较低两个水平的学生各20名作为情绪智力高分组和低分组。通过序列递减任务诱发负性情绪,比较两组被试在负性情绪的情境下的情绪体验差异。结果发现,情绪智力水平高分组在负性情绪诱发情境下,会自动化地调节和控制自己的情绪;而情绪智力水平较低的个体,则未对自己的情绪进行自动化的控制和调节。
Emotional intelligence plays an important role in individual emotion regulation. A sample of 370 college students was tested by Emotional Intelligence Scale. 20 students of higher scores and 20 students of lower scores from this sample were randomly selected to do the next test. Serial Subtraction Task which can elicit negative emotion was used to test the effects of the Emotional Intelligence on individual emotion regulation. The results showed that the students with high Emotional Intelligence could automatically control their emotion in the negative emotion-eliciting context, but the students with low Emotional Intelligence would not control their emotion in this kind of context.

Abstract: Turbo码采用修正的BAHLetal.算法实现解码.这是一种基于软值的概率迭代解码算法.本文在保持Turbo码迭代软解码算法优点的基础上,充分利用Turbo码编码器结构这一确知条件,结合代数解码原理,提出了一种Turbo码概率-代数联合解码算法.该算法结合了概率解码和代数解码的优点,又有效避免了误差传播的发生,使Turbo码的纠错性能在原经典算法的基础上得到进一步的提高.该算法不仅为降低Turbo码的比特误码率和误差地板值提供了一种新的研究途径,而且因其更好的纠错性能而具有十分明显的实用价值.仿真实验结果显示,在比特误码率(BER)为10-3~10-4时,与经典Turbo码解码算法相比,采用该算法能获得0.1dB左右的编码增益.

Abstract: 利用ccm1(r15l7)-lnwp模式,以1996年3月17日的国家气象中心客观分析资料为初始场,分别采用有、无青藏高原两种方案,数值研究了青藏高原对5月份全球大气环流季节转换的影响。试验结果表明:北半球初夏,青藏高原区域用同纬度地区的一个中空热源,其作用可以在200hpa层形成一个224k的暖中心,使大气增暖7k以上。高原地形的动力和非绝热作用使得南极大陆200hpa层大部分地区降温6k左右,最大负中心可达-8.28k,这对于南半球由夏至冬过程中,环极涡旋的强度加深和范围扩大是有利的。高原地形作用对北半球大气环流平均槽脊的形成和维持有十分重要的影响,它加强了高原所在纬度带北侧(减弱了南侧)由南向北的正温度梯度,同时也增强了30°s附近由北向南的正温度梯度,从而有利于季节转换过程中全球中纬西风带的整体北移和初夏亚洲季风环流的形成。同时高原地形作用在赤道及低纬地区形成的位势增加区,有利于南半球热带高压脊的北退和北半球副高增强北移。此外,它还有利于南半球极地东风带的增强和500hpa层环极低压带的强度减弱,同时增加了罗斯海附近的极涡强度,对赤道的索马里急流的形成也有重要影响

重庆交通大学学报(自然科学版) , 2012, DOI: 10.3969/j.issn.1674-0696.2012.03.40
Abstract: :?在运用热脱附-气相色谱/质谱(TD-GC/MS)联机技术分析杨木粉末无胶温压成形复合材料在4,60,90和160℃等4个环境温度点的挥发物总离子流图的基础上,采用色谱峰面积归一化法鉴定出杨木粉末基复合材料在各温度下的保留时间及峰面积,进而评价杨木粉末基复合材料的环境友好性。结果表明:在不同温度下,杨木粉末基复合材料挥发物中的有益成分含量明显多于有害成分,在40,60和160℃时,有益成分含量为有害成分含量的6倍以上,90℃时有益成分为有害成分的29倍,环境友好性良好;杨木粉末基复合材料总挥发物种类及有益成分种类、有害成分种类与杨木原粉相应种类大致相当,但有益成分明显增多,有害成分减少,增减幅度较大。说明这类杨木粉末基复合材料不仅无胶温压成形工艺具有环境友好性,且其制品的制备和使用过程都具有环境友好性。

Abstract: An MAC protocol named PMCAP/CDMA is introduced and utilized in voice/data integration network for uplink channel of CDMA mobile communication systems. Mathematical model is built and performance analysis is conducted. Three code sets for voice contention, data contention and voice/data reservation are adopted so that there are no contentions between voice and data users. Two adaptive code-set-assign methods are proposed. Simulation shows, compared with fixed assigned method, adaptive method can greatly improve the system performance. And the second adaptive code-set-assign method is a good trade off between voice drop rate and data delay.

Abstract: Throughput performance for Slotted ALOHA DS/CDMA (S-ALOHA-DS/CDMA) and Multicarrier Slotted ALOHA (MC-S-ALOHA) systems is performed and compared in this paper. Theory analysis and computer simulation results of throughput of S-ALOHA-DS/CDMA are obtained using different error correcting code. And comparison results with MC-S-ALOHA system are also obtained. It is proved that with the traffic increasing, the S-ALOHA-DS/CDMA with high error-correct code being used has better throughput performance. In the case of the too heavy traffic, the MC-S-ALOHA system has better throughput performance. If the total codes of the system are limited, the code contention collision will occur so that throughput will drop.
