It also used this theory to improve the battery system in the new energy verticals. Firstly, this essay used the theory of evolution from TRIZ to analyze different kinds of graphs which show
干扰温度约束下的一种新的中继选择策略
A New Relay Selection Strategy under Interference Temperature Constraint

Abstract:
协作通信中的一个关键问题是如何分配和管理中继节点,尤其在次用户系统受到干扰温度约束条件下,协作方案的设计不仅要最大限度的提高系统性能,而且需要控制次用户系统对主用户系统的干扰。针对这种情况在次用户系统中提出一种基于协作波束形成中继选择策略,该方法以最小化次用户系统中断概率为目标,推导出一个中继选择门限,保证了有限的传输功率只分配给高效的中继链路,从而提高系统传输性能。仿真结果显示,该建议方法优于单中继转发方案和全中继转发方案,能有效降低次用户系统中断概率。
One of the key problems in cooperative communication is how to allocate and manage the relay nodes, especially in the secondary user system under the interference temperature constraint. The design of the collaborative scheme should not only maximize the performance of the system, but also need to control the secondary user system’s interference in the primary user system. For this situation, a relay selection strategy is proposed based on the collaborative beamforming in the secondary user system. To minimize the outage probability of the secondary user system, a threshold is determined which only allocates the transmission power to the efficient relay links to improve the transfer performance of the system. The simulation results demonstrate that the proposed strategy can effectively reduce the outage probability of the secondary user system, and more over, it is better than the Single Relay Amplify-and-Forward (SAF) scheme and the All Relays Amplify-and-Forward (AAF) scheme.

新星和超新星

现代物理知识 , 2004,
Abstract: 当你仰望夜空 ,是否为那静谧的星空所倾倒 ;你是否为那发出淡淡蓝光的星星所陶醉。其实 ,星空并不安静 ,星光并不微弱。那看似微弱的星星内部大都正进行着剧烈的热核反应以维持自身的存在。我们的太阳 ,也跟它们一样在不断与死亡做斗争。可是你知道 5 0亿年后 ,太阳燃料快耗尽时它的情形吗 ?现在就让我通过对一般恒星晚年的介绍来简单说一下太阳晚年的情形吧。一、新 星有时在空中原来看不见星的地方 ,会突然出现一颗很亮的星。亮度在几天内迅速增加 ,在达到极大之后又逐渐减弱。几年或几十年后 ,星星会慢慢消失。这就是新星 ,也叫客星。它…

日本宪法上的知情权与信息公开法

法学家 , 2007,
Abstract: 对日本信息公开法上的知情权的宪法依据,日本法学界认识不一致。一些学者认为宪法第21条规定的“表现的自由”等条款为知情权的宪法依据,也有学者认为宪法序言中“国民主权”表述为知情权依据。信息公开法未使用“知情权”概念,而强调“国民主权”和政府的“说明责任”。国民主权与知情权属不同层次的概念,在法律条文中同时出现并不矛盾。为保护和发展公民权利,“知情权”应当在信息公开法中得到确认。
