摘要：We have theoretically investigated two series of cyclometalated Pt(Ⅱ) complexes,a series [Pt(C,N,N) Cl] and b series [Pt(C,N,Npyrazolyl) Cl].The geometrical and electronic structures are calculated at the ECP60MWB//6-31G*(H,C,Cl,N,S) basis set level using DFT method;one-photon absorption(OPA) properties are calculated by using both TDDFT and ZINDO methods and two-photon absorption(TPA) properties are obtained with the ZINDO/SOS *** resonance integrals parameters(βsp and βd) for Pt are adjusted to -1 and -28.5 eV,respectively,to make max OPA wavelength calculated by ZINDO closest to the experimental data and TDDFT *** calculated results indicate the molecule 2b([Pt(Cnaphthyl,N,Npyrazolyl) Cl]) has the biggest potential as outstanding TPA materials because(i) the TPA properties of b series are more outstanding in IR wavelength range,the molecules in b series have good transparencies and possess 1-pyrazolyl-NH that is also available for another metal coordination(e.g.,dimerization) and chemical interactions;(ii) when C is Cnaphthyl in the C,N,N ligand of cyclometalated Pt(Ⅱ) complexes,the molecules have the best conjugation effect and the best TPA properties.

摘要：Based on the current indoor natural ventilation and lighting in the space of traditional residential buildings,this paper starts from the passive-design optimization of the spatial natural ventilation and lighting,and makes quantitative evaluation on the quality of current interior natural ventilation and lighting for two typical residential buildings by three indexes,including wind speed,static wind area ratio and satisfaction ratio about minimum lighting coefficient. Based on that, this paper conducts the passive design optimization, and establishes the quantitative association and reevaluation among the passive reformation design, natural ventilation,and lighting environmental quality,proposing the general strategy for the existing residential buildings to respond to the passive reformation design of the natural ventilation and lighting. The special reconstruction of core functionary space of integration of "the living room + dining room + partial space"is researched,and the redesign for the optimization and replacement of both indoor and outdoor enclosure parts is explored,which is expected to provide practical exploration on the strategies for passive construction of spatial natural environmental quality within a large number of highly-energy-consumed residential buildings in China,as well as the green design of residential buildings.

摘要：To meet the requirements and functions of spacecraft dynamic simulation and emulation according to different flight periods, the realization of real time system with different configurations, control of the development cycle and examples of application are presented in detail. On the basis of the satellite dynamic simulation technology, distributed network integrated with the component testing platforms is used to construct a multi-level bus network system. The system takes into full consideration the configuration flexibility, real time characteristics and extendibility. Test results show that both the software algorithm and the hardware integration of the system are correct and effective. The system could be used not only as the effective tool of designing and developing the components and whole assembly of satellites and missiles, but also for the dynamic simulation and emulation in all phases of a spacecraft development cycle.

摘要：为了提高六自由度轻量型机器人的轨迹跟踪精度同时减小其同步误差,提出一种基于相邻耦合误差分析的非线性PD偏差耦合同步控制方法。建立并验证了该机器人的数学模型,包括运动学模型、动力学模型以及样条轨迹规划。因为难以描述复杂轨迹下的机器人实时轮廓误差,因此本文引入相邻耦合误差来解决这一问题。结合机器人非线性控制以及耦合特性,设计了非线性PD偏差耦合同步控制器,并通过仿真分析进行验证。伺服控制试验系统由激光跟踪系统、机器人机械系统以及基于EtherCAT通讯的伺服控制系统构成,实验数据表明,该控制方法可使机器人同步误差大幅度减小,并且最大跟踪误差由0.33 mm缩减到0.1 mm。实验结果验证了控制算法的有效性,从而证明了该控制策略能够有效改善机器人的轨迹跟踪精度。
