摘要：A novel solar heat pump water heater integrated with collector, storage and evaporation （SHPWHICSE） is presented and analyzed. By adding phase-changing materials into the collector/storage/evaporator, the solar energy can be absorbed and storied as latent heat. Calculating the storied energy according to temperature variation of the phasechange material which is chosen as paraffin, the result is that the storied energy can meet the heat load of this system. Solar got efficiency of this system is defined and compared with the direct expansion solar heat pump water heater. Experimental studies of SHPWHICSE with 150L water heating capacity are done at typical weather conditions in spring. The results indicate the system＇s COP is 5.63 on sunny days. Although on overcast or rainy days, the system＇s COP can reach 4. 13. Moreover, solar radiation intensity＇s unstable change has little influerace on the solar got efficiency and COP. Therefore, SHPWHICSE can be operating highly efficiently and stably at various weather conditions for domestic hot water.%介绍并研究了一种新型集热／蓄能／蒸发一体化太阳能热泵热水器系统（SHPWHICSE）．该装置将真空管集热器、蓄能容器和蒸发器集于一体，通过相变潜热吸收并储存大量太阳能．根据相变材料（石蜡）在吸、放热过程中温度的变化计算蓄热量，确定相变材料中储存的热量能够满足系统热负荷．定义了一体化太阳能热泵系统的得热效率，并和直膨式太阳能热泵热水器得热效率进行比较．在春季典型工况下对容量为150L的SHPWHICSE进行实验研究，结果表明：晴天工况下，系统COP可达5．63；即使阴雨天，COP也可达4．13；太阳辐射强度的不稳定变化对热泵系统得热效率和COP的影响不大．因此，该系统在各种天气条件下都可以高效稳定地制取生活热水．

摘要：对一种瓦斯燃烧器的火焰流场进行了数值计算,根据计算结果对火焰回流区进行了分析.针对瓦斯燃烧器的结构特点,将燃烧区域的流动简化为二维轴对称流动.对不同空气和瓦斯流速时的计算结果表明,火焰中心及两排空气引射管间出现回流区,火焰中心的回流区占主要地位.空气流速越高,回流区越大,但回流区距燃烧器出口越近,甚至进入燃烧器.瓦斯流速对火焰回流区的作用规律与空气相反,瓦斯流速较高时,中心回流区将显著变小,距燃烧器出口距离较远,两排空气引射管间的回流区消失.计算结果可为瓦斯燃烧器选用适当的空气和瓦斯流速提供依据.%The flame flow field of a gas burner was investigated by numerical method. The flame circumfluence was ana- lyzed with calculation results. The flow was simplified into two dimensional axisymmetric flow according to characters of gas burner structure. Numerical simulations were performed with different velocities of air and gas. Results showed that there were two cireumfluences in flow area. One was at the centre of flow area, the other was between two jets of air. The higher the air speed was, the wider flame circumfluence was. And the eircumfluenee was nearer to outlet of the burner, even entered into the burner when air velocity got higher. The impact of gas velocity on the circumfluence was opposite to that of air velocity. When gas flowed at a relative high velocity, the eircumfluenee at the centre became obvi- ously smaller and was rarer away from the outlet. This study can provide guidance for choice of appropriate velocity of air and gas in gas burner.
摘要：Detecting interharmonics for flicker troubleshooting is highly desirable. Whereas these interharmonics are close to harmonic or fundamental component, it is always swamped by the main-lobe of harmonic nearby if the harmonic amplitude is much bigger than interharmonic amplitude, and vice versa.

It is shown by matlab simu- lation that the new method enioys higher frequency resolution and is more nrecise than traditional anag_%邻近谐波或基波的间谐波,是导致电压闪变的直接原因,准确检出该成分,对于改善电能质量具有重要意义.针对真实电网宽带多频的信号特性,提出了一种改进的间谐波分析法—加窗插值MUSIC法,该方法克服了加窗插值和MUSIC算法的局限.Matlab仿真表明加窗插值MUSIC法频率分辨率和精度优于加窗插值,相对传统求根MUSIC不需要估算信号个数,能有效消除伪谱的影响.
摘要：界程逻辑中的并发模态副词是观察进程交互行为的关键因素之一,但引入并发模态副词又会导致模型检测的不可判定性.针对这一问题,提出了可判定的、描述移动界程演算进程的空间结构和行为性质的应用界程逻辑.该逻辑定义了空间模态词和行为模态词来直接观察移动进程的空间性质和潜在交互行为性质,并定义了不动点公式来刻画进程的递归性质.为了证明逻辑公式的指称语义的正确性,引入了性质集的概念并证明两者之间的一致性.最后给出了使用应用界程逻辑公式来描述一个资源传输系统在时间和空间上的行为性质的实例.%A decidable ambient based spatial logic, named Applied Ambient Logic is proposed, which consists of spatial modal connectives and behavioral modal connectives. In traditional ambient logic, the composition adjunct is very ex- pressive, which makes it possible to observe behavioral properties of processes. However, it is proved that model-chec- king of logics with composition adjunct is not decidable. In Applied Ambient Logic, both spatial modal connectives and behavioral modal connectives are added which can specify spatial and behavioral properties of processes directly, and fix- point modals are also added for properties of recursive processes. A concept of property sets is adopted to describe the features of denotational semantics for logic formulas, and soundness between property-set and denotational semantics is proved. Finally, examples of Applied-Ambient Logic formulas are given which are applied to describe spatial-temporal behavioral properties of a resource transformation system model.
摘要：The experiments of the rice husk pyrolysis were performed in a fixed-bed reactor to produce bio-oil. The effects of the different operation factors such as pyrolysis temperature, sweeping gas （ N2 ） flow rates and heating rates on the yields of three products and the characteristics of bio-char were investigated. The maximum bio-oil yield of 49.91% was obtained at 550~C pyrolysis temperature with a heating rate of 25~C/min and nitrogen flow rate of 150 mL/min. As the heating rate increased, it favored the yields of liquid product, yet the bio-char yields decreased. Thermogravimetric analysis （TGA） was introduced to study the thermal decomposition of the feedstock. Crystals and morphology of bio-char with different pyrolysis temperatures were characterized by X-ray diffraction （XRD） and scanning electron microscopy （SEM） analysis. The results showed that pyrolysis temperatures played an important role on the surface morphology and crystal phase of bio-char and the prominent porosity with the bio-char which was generated under 550%; pyrolysis temper- ature was observed.%以稻壳为研究对象,在固定床中热解制取液体生物油.实验研究了热解温度、氮气流速和升温速率对热解3种产物分布的影响.在25℃/min的升温速率达到热解终温550℃,氮气流速为150 mL/min工况下液体产率达到最大值49.91%.随着升温速率的增加液体产率升高,焦炭的产率降低.利用热重分析考察了原料的热分解特性.通过X射线衍射方法和SEM对热解焦炭的晶相和形态进行分析.研究表明热解温度对焦炭的晶相和表面形态的影响很大,在550℃的热解温度下得到的焦炭有较突出孔状结构.

This paper proposes a new algorithm by which the minimum cut graph cut problem is converted into the greedy algorithm to reduce the complexity of the problem. At the same time as the transformed graph cut has a low effect in dealing with the image continuous problem, we propose the graph cuts combined with the region matching algorithm called GR （ Graphic Cut in Region） algorithm. They not only apply the Graph cut algorithm theory to the stereo matching problem, but also use a new method which computes the initial disparity cost through sealing the SAD window and twice compute the window cost to improve the accuracy of the initial disparity. The experiments show that this new algorithm in image continuous region has a better effect, and significantly improves the accuracy of matching at this time, and also that the algorithm complexity is greatly reduced.
