Numerical Simulation and Experimental Investigation on A Thermoacoustic Engine with Tapered Resonance Tube A symmetrical standing-wave thermoacoustic engine with tapered resonance tube has been numerically simulated with liner thermoacoustics. The simulation shows that using tapered resonance tube in thermoacoustic engine could decrease the velocity amplitude and lower the total acoustic power loss in the resonance tube. The experimental results indicate that the harmonic was suppressed effectively by using the tapered resonance tube, and the pressure ratio was improved.

采用锥形谐振管的热声发动机的数值模拟和实验研究利用线性热声理论，对一台采用锥形谐振管的驻波型热声发动机进行了数值模拟，发现采用锥形谐振管可有效降低工质气体的速度振幅，进而减小在谐振管中声功率的损失；与一台在相同频率下工作的采用等直径圆柱谐振管的驻波型热声发动机进行了实验对比，结果表明，在使用锥形管作为谐振管的热声发动机系统中，谐振管中的非线性效应得到了明显的抑制，热声发动机在基频模式下稳定运行，压比增大而加热温度降低。

Flocculation+0.45μm filter is selected as the pretreatment of the method proposed here.(9) A set of standard methods for ASMs COD characterization is suggested in the thesis and it advantages are:①Respirometry is adopted to measure RBCOD and SBCOD;②SI is determined from raw wastewater and so there is no influence of inert products;③Heterotrophic biomass in wastewater is measured;④The key instrument used in the standard methods-hybrid respirometer, has high automatic level and friendly user interface which simplifies the respirometry. So the suggested standard methods are practical.(10) According to the suggested standard methods, the influent COD of a wastewater treatment plant in Chongqing, China, is characterized.

9提出一套表征城市污水COD组分的标准化方法建议，其特点在于：①以呼吸测量作为RBCOD和SBCOD的测量方法，与以往以物理化学方法为主的做法有着本质区别；②对原水直接进行分析测试来获得SI组分，不受溶解性惰性产物的干扰；③考虑了污水中活性异养微生物组分的单独测量；④所依赖的核心仪器-呼吸测量仪具有很高的自动化程度和简单友好的用户界面，使原本复杂的呼吸测量实验及其结果的分析统计简单化，所建议的标准化方法具有很好的实用性。

The immune level tested in different time after injection with ginkgolic acids in sensitization mode showed that the expression of CD3〓 and CD4〓T lymphocytes increased, but CD8〓 was restrained, while the B lymphocytes was also increased. The results suggested that sensitivity was approved and T lymphocytes proliferation was induced, which strength cell immunity responsion, at the same time B lymphocytes was differentiated to IgE antibody-producing cells when contacted with ginkgolic acids as allergen.

大鼠经致敏方式接触银杏酸后，在不同时间的细胞免疫水平与体液免疫水平的研究结果表明，大鼠CD3〓及CD4〓T淋巴细胞的表达增加，而CD8〓T淋巴细胞的表达受到明显抑制，同时参与体液免疫的B淋巴细胞百分率呈增高趋势，提示银杏酸可能作为变应原使机体敏感性增强，诱导T细胞分裂增殖，增强细胞免疫应答，同时促进B细胞增殖分化成IgE抗体产生细胞。

Taking the moments of hip and knee joint as its controlled variables, the simulation of the motion equation shows that: After increasing the joint moment at the cushioning phase, the vertical velocity of the body center of mass distinctively speedup while horizontal velocity fall to some degree. Thus, the resultant velocity remains basically constant, but the result distance of long jump can be increased due to the enlargement of the angle of take-off.

以髋、膝关节肌力矩作为运动方程的控制变量，对其修改后的模拟结果表明：增大缓冲阶段的关节肌力矩后，人体重心的垂直速度得到明显提高，而水平速度则有所下降，在腾起合速度变化不大的情况下，由于腾起角的增大提高了跳远成绩。

According to senior author Howard Rockman, MD, also from Duke, the physical linkage of the receptors could allow physicians more flexibility in heart failure treatment. Because angiotensin blockers are better tolerated, they could be given alone to patients too sick to take beta-blockers. A single, potent drug targeting both receptors could reduce the need for multiple medications with increased potential for drug interactions and adverse events.

Howard Rockman指出，这些药物在治疗心脏衰竭的成效可以归因于它们并非以单一受体作为目标，这些研究结果也可以为心脏衰竭的患者订作药物疗法，不同受体的补体在不同患者及不同的疾病严重性之间有所差异，所以辨识患者单一性受体组成的血液试验，将可以让内科医生指定最适当药物治疗。
