关于人体经络的一个试探性观点

在考察针刺穴位治疗作用的基础上，根据现有的实验事实，将人体经络的观念和经改进后的神经-内分泌-免疫系统的观念统一起来，提出人体经络是具有敏感节点和功能连接的神经-内分泌-免疫网络的假说。人体经络的复杂网络不仅是遍及全身的系统，而且可以通过敏感节点及其功能连接对身体起调控作用。

旅华日本、韩国游客旅游特征及偏好研究

以2004年在北京、上海、广州、桂林、昆明和西安6个热点旅游城市进行的随机抽样调查数据为依据,运用旅游地理学基本原理、心理学分析和比较分析等研究方法,从人口统计、旅游活动及偏好等方面对旅华日本和韩国游客进行了定性和定量的分析,总结出游客基本特征:游客以观光为主要目的,团队多于散客,大部分游客都有1～3次的来华经历;停留时间多为4～7 d;主要目的地是北京、上海和西安;偏好民俗文化类活动和中国传统工艺品.同时通过对比揭示两国游客的共性和差异,并提出一些建议,希望对进一步拓展日韩客源市场提供帮助.

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.     

Method of Homomorphic Encryption

The existing homomorphie eneryption scheme is based on ring of the integer, and the possible operators are restricted to addition and multiplication only. In this paper, a new operation is defined Similar Modul. Base on the Similar Modul, the number sets of the homomorphic encryption scheme is extended to real number, and the possible operators are extended to addition, subtraction, multiplication and division. Our new approach provides a practical ways of implementation because of the extension of the operators and the number sets.

改善20CrMnTiH淬透性的研究

莱钢特钢厂20CrMnTiH钢材成分波动较大,淬透性带HRC8～10,范围较大,制约了齿轮钢质量的进一步提高.通过研究,发现铸坯中心偏析尤其是碳偏析为主要问题.通过工艺优化采取各项措施,尤其增加电磁搅拌后,中心碳偏析得到明显改善;C控制在0.19%～0.20%的炉次达到了95.6%;淬透性带控制在HRC6内的达到了92.1%;在HRC4内的达到了86.2%;提高了产品质量,满足了用户需求.
