基态He2Ne^＋的分析势能函数

本文首次用ＣＩＤ／６－３１Ｇ法计算了Ｈｅ２Ｎｅ＾＋（Ｘ＾２∑＾＋）的平衡键长、离解能和谐性力学数。应用简化的多体项展式法，导出了Ｈｅ２Ｎｅ＾＋（Ｘ＾２∑＾＋）的分析势能函数。在Ｈｅ２Ｎｅ＾＋（Ｘ＾２∑＾＋）势能面上有一个线性的平衡结构和一个弯曲的亚稳结构，有两个线性鞍点和两个非线性鞍点。发现并改正了Ｋｕｎｔｚ等人的Ｎｅ２Ｎｅ＾＋势能面的不合理离解极限，获得正确的Ｎｅ２Ｎｅ＾＋势能面。     

侧面柱碰撞的研究

交通事故表明，车辆与柱状物发生侧面碰撞而导致乘员重度伤害的比例较高，因而对侧面柱碰撞的研究是必要的。基于力学理论对这种特殊的侧面碰撞形态进行分析，同时以乘员伤害和车身变形作为指标。对三种不同形式国产轿车的试验结果进行比较。可找出侧面柱碰撞与一般侧面碰撞间的差别，进而为车身侧面结构的改进提供参考依据。     

一种适用于沪杭磁悬浮工程的坐标系

为更好地满足沪杭磁悬浮工程全线施工定线的需要，提出了引用一种新型大地坐标系的设想,该坐标系仍以经纬线构成椭球面上的坐标格网，但点位则用长度量表示．由此不仅可统一全线用于施工定线的坐标系，而且能杜绝投影变形，方便而精确地求解长度和角度，这已由计算结果所证实.

以提高燃料经济性为目标,采用基于瞬时优化的方法开展能量分配策略研究,并引入了蓄电池等价燃料消耗理论,将蓄电池电能消耗或者电能补充,等效为燃料电池发动机的燃料消耗量,并由此建立系统瞬时燃料消耗量函数.为保证蓄电池工作在最优的范围内,引入蓄电池的充电保持策略.仿真结果表明,按照等价燃料消耗量瞬时优化理论得出的优化结果,能提高燃料经济性,同时蓄电池SOC保持在合理范围内,对今后实车的研制具有一定指导意义.     

Artificial anal sphincter with sensor feedback powered by transcutaneous energy transmission

This artificial anal sphincter (AAS) is used to help patients who are in severe incontinence. It consists of two parts. The first part is taken outside with patients. The second is implanted in the bodies to provide independent evacuation for patients. It is powered through transcutaneous energy transmission by the first part. There are two sensors in the second part. One sensor measures the pressure in the cuff-clamp around the recta. The other measures the pressure of the recta. As soon as the pressure measured by the later reaches the threshold, a signal is sent out to patients through wireless communication to alarm patients preparing defecation. Patients can give a start signal to begin defecating after they are ready. And they can also give a signal to stop defecating like a healthy person. With the aids of the novel medical device, patients can defecate as a healthy person. The first generation of this AAS is presented.     

Reflections on energy issues in China

Energy, which has a bearing on both economic and national security, is of importance and a major constraining factor to the economic and social development of China. The article analyses the current worldenergy status and development trend from the perspectives of resources, production and consumption and in thecontext of its implications on the environment and economic and social development, and explores opportunitiesand challenges for China's energy development. With a focus on the strategy of energy development in China,the author proposes a new energy development approach with Chinese characteristics whose main elementsare: energy-saving, high-efficiency, diversified development, environment protection, technology guidance andinternational cooperation. In other words, China is striving to build a reliable energy production, circulationand consumption system that is efficient, technologically advanced, low polluting and ecologically friendly. Along-term development strategy with priority on energy conservation, efficient utilization of primary energyand advanced electricity system is expounded in the paper. The author also describes the prospect of energytechnology development and stresses the implementation of energy strategy by further improving energy policyand related mechanisms, strengthening macro-management and the essential role of the market in resourceallocation so as to ensure the economic and social development of China through reliable energy supply.

The evaluation of transportation energy efficiency: An application of three-stage virtual frontier DEA

In this paper, transportation energy efficiency is newly defined and its inputs and outputs are obtained through literature review. Labor input, capital input and energy input are selected as the inputs, passenger turnover volume and freight turnover volume are defined as the outputs. A new model—three-stage virtual frontier DEA (three-stage virtual frontier Data Envelopment Analysis) is proposed to evaluate transportation energy efficiencies. The case of thirty Chinese PARs (provincial administrative regions) from 2003 to 2012 is applied to verify its rationality. In the three-stage virtual frontier DEA, the reference DMU (decision-making unit) set and the evaluated DMU set are two different sets so that it can distinguish the DEA efficient DMUs. And in the evaluating process, the reference DMU set remains unchanged to assure its results more reasonable than Super DEA model. The results show that transport structure and management measures have important impacts on transportation energy efficiency.
