摘要：A great deal of benefits can be achieved if information and process are integrated within the building design project. This paper aims to establish a prototype of workflow management system for construction design project through the application of workflow technology. The composition and function of prototype is presented to satisfy the needs of information share and process integration. By integrating all subsystems and modules of the prototype, the whole system can deal with design information-flow modeling, emulating and optimizing, task planning and distributing, automatic tracking and monitoring, as well as network service, etc. In this way, the collaborative design environment of building design proiect is brought into being.

摘要：研究了不确定奇异分数阶系统的鲁棒稳定和镇定问题.在该系统里,状态矩阵的不确定参数通常假定为时不变和范数有界的.首先设计一个可预测的控制器使得不确定奇异分数阶正则;然后设计一个输出反馈控制器使得正则后的系统稳定,这样可以得到当分数阶阶次在[1,2)时系统鲁棒渐近稳定的充分条件;最后通过一个数值仿真证明了该方法的有效性.

摘要：A scheme to design a simultaneous multichannel receiver is proposed to process multichannel signals in parallel, which is achieved by exploiting the attractive characteristics of a fast filter bank（ FFB）, such as cascaded structure, high frequency selectivity and lowcomputational complexity. Based on the minimization of the objective function, quantified in terms of the total number of multiplications required, subject to prescribed allowable ripples in the passband and stopband, the impulse response coefficients of the prototype filter in each stage are obtained to meet the requirements of the overall specifications for each channel at the receiver side. Simulations and experimental results on the frequency modulation（ FM） broadcast mutlichannel signal receiving system with the FM range from88 to 108 MHz, built upon the proposed FFB structure, are performed to verify its performance. Those results indicate that the proposed scheme is efficient in FM audio indexing applications and has a lower computational complexity, which is approximately 66. 4% of the weighted overlap and add（ WOLA） filter banks based solution.

摘要：A series of WO3 samples with different crystalline phases were prepared by the thermal decomposition method from ammonium tungstate hydrate.X-ray diffraction（XRD）,scanning electron microscopy（SEM）,high-resolution transmission electron microscopy（HRTEM）,X-ray photoelectron spectroscopy,and N2 adsorption-desorption were used to characterize the crystalline phase,morphology,particle size,chemical composition,and surface area of the WO3 *** formation of hexagonal（h-WO3） and monoclinic（m-WO3） crystal structures of WO3 at different temperatures or different times was confirmed by XRD.m-WO3 is formed at 600 ℃,while m-WO3 starts to transform into h-WO3 at 800℃.However,h-WO3,which forms at 800℃,may transform into m-WO3 by increasing the calcination temperature to 1000℃.SEM results indicate that m-WO3 particles exhibit a bulky shape with heavy aggregates,while h-WO3 particles exhibit a rod-like ***,m-WO3 crystals are sporadically patched on the surface of the h-WO3 rod-like particles,resulting in the exposure of both m-WO3 and h-WO3 on the *** is observed that the monoclinic phase（m-WO3）/hexagonal phase（h-WO3） junction was fabricated by tuning the calcination temperature and calcination *** relative ratios between m-WO3 and h-WO3 in the phase junction can readily be tailored by control of the calcination *** photocatalytic activities of WO3 with different crystalline phases were evaluated by the photocatalytic degradation of rhodamine B as a model pollutant.A higher photocatalytic activity was observed in the WO3 sample with the m-WO3/h-WO3junction as compared with the sample with only *** improvement of photocatalytic activity can be attributed to the reduction of the electron-hole recombination rate owing to the formation of the phase junction,whose presence has been confirmed by HRTEM and photoluminescence spectra.

摘要：背景:胎盘和胎膜在母胎液体平衡过程中起着重要作用,而水穿过胎盘和胎膜运输的分子和细胞机制目前尚不十分清楚,推测母胎液体交换可能通过胎盘和胎膜上的水通道进行。目的:观察人正常妊娠晚期胎盘与胎膜组织中水通道蛋白8蛋白质水平的表达及其分布。设计、时间及地点:对比观察,于2005-07/12在广州医学院实验中心完成。材料:收集正常足月妊娠剖宫分娩的胎盘与胎膜组织样本各5例,产妇年龄(27±5)岁,实验方法获医院伦理委员会批准。方法:胎盘胎膜组织在分娩30min内取样,用无菌生理盐水漂洗干净去除血液,立即放入液氮中,转运至-80℃冰箱保存备用。主要观察指标:运用反转录-聚合酶链反应法、免疫组织化学法及Western印迹法检测水通道蛋白8在胎盘与胎膜组织中的表达与分布。结果:反转录-聚合酶链反应显示,水通道蛋白8mRNA在胎盘和胎膜组织中均有表达。水通道蛋白8 Western印迹检测胎盘和胎膜组织显示,一特异性条带在Mr45000左右。免疫组织化学结果显示,水通道蛋白8表达于胎盘合体滋养细胞、羊膜上皮细胞及平滑绒毛膜细胞滋养细胞。结论:在蛋白质水平显示,水通道蛋白8表达于胎盘的合体滋养细胞、羊膜上皮细胞及平滑绒毛膜细胞滋养细胞。

摘要：In order to detect and process underground vibration signal, this paper presents a system with the combination of software and hardware. The hardware part consists of sensor, memory chips, USB, etc. , which is responsible for capturing original signals from sensors. The software part is a virtual oscilloscope based on LabWindows/CVI （C vitual instrument）, which not only has the functions of traditional oscilloscope but also can analyze and process vibration signals in special ways. The experimental results show that the designed system is stable, reliable and easy to be operated, which can meet practical requirements.

摘要：东皋禅师在日本从事的文化传播和交流活动,不仅对于日本文化的发展和中日文化交流贡献极大,而且,在我们今天研究明清文化的有关问题上,也给予很大的帮助。类似《东皋琴谱》的音乐文化现象,明清以来还存在不少,《幽兰琴谱》、《魏氏乐谱》、《清乐曲谱》等等,都与中国明清时期音乐历史、明清中国传统音乐、民间音乐、文人音乐等密切相关。中日双方的携手与互动研究能够使这些问题更加深入地得到解决。
