太阳能小屋的设计

建立以光伏电池在寿命期内总利润最大的数学模型,展开对太阳光直射、散射和反射辐射量的分析,获得理论上的最大赢利方案,再结合小屋墙面和屋顶的形状,选取光伏电池的最优安装方式。针对架空方式安装光伏电池,以总辐射最大为目标,确定了安置光伏电池的最佳倾角。在此基础上设计新的太阳能小屋,并在满足相关建筑要求的前提下,取得了优化的效果。     

Evaluation of cilazapril in vasovagal syncope treatment

Objective: to evaluate cilazapril in vasovagal syncope treatment. Method: eighty-six cases of VVS patients found positive in TTT tilt were medicated with 2.5 mg cilazapril daily for three months and followed up by TTT. Results: seven cases quit due to cough or unexplained reason; 79 VVS patients had no more fainting spells; 75.95% of TTT results of patients changed to negative after 3 months therapy. The before and after cilazapril treatment average blood pressures (taken in lying position) were 121/73 mm Hg (1 mm Hg=0.133kPa) and 120/76 mm Hg respectively (P>0.05); and mean heart rates were 68.63±12.37/min and 70.13±13.15/min respectively with no significant changes (P>0.05). Conclusion: Cilazapril was effective in treatment of VVS; did not affect normal blood pressure and heart rate; was safe; and had little side effect.     

三维跟踪扫描影像分析方法的实现与精度分析

三维影像分析是运动生物力学的重要研究手段之一,广泛地应用于运动技术分析和诊断中.三维跟踪扫描影像分析方法就是摄像机跟踪运动目标来记录运动的图像,并通过专门的图像解析系统解算得到运动目标空间实际三维坐标的方法.应用SIMI Motion的Pan/Tilt/Zoom功能来实现三维跟踪扫描录像分析,并对所得到的三维测量数据的精度进行评价和分析.研究结果表明,在相同的坐标参考系下,由全站仪和影像分析测量得到的24个点的三维空间绝对坐标的平均相差值为0.018±0.003 m,三维跟踪扫描影像测量的相对误差可以达到1.97%,这样的测量精度可满足运动技术分析的要求.介绍了实现三维跟踪扫描影像分析的全过程,对影响测量精度的因素进行了初步的分析,并提出了应采取的相应措施.
