| 1 | Analytical and finite-element study of optimal strain distribution in various beam shapes for energy harvesting applications显示文摘Owing to the increasing demand for harvesting energy from environmental vibration for use in self-powered electronic applications, cantilever-based vibration energy harvesting has attracted considerable interest from various parties and has become one of the most common approaches to converting redundant mechanical energy into electrical energy. As the output voltage produced from a piezoelectric material depends largely on the geometric shape and the size of the beam, there is a need to model and compare the performance of cantilever beams of differing geometries.This paper presents the study of strain distribution in various shapes of cantilever beams, including a convex and concave edge profile elliptical beam that have not yet been discussed in any prior literature. Both analytical and finite-element models are derived and the resultant strain distributions in the beam are computed based on a MATLAB solver and ANSYS finite-element analysis tools. An optimum geometry for a vibration-based energy harvesting system is verified.Finally, experimental results comparing the power density for triangular and rectangular piezoelectric beams are also presented to validate the findings of the study, and the claim, as suggested in the literature, is verified. | B.L.Ooi J.M.Gilbert A.Rashid A.Aziz | 2016 | Acta Mechanica Sinica2016，32，4： | 8 |
| 2 | 应用鸡胚作抗球虫药筛选的研究显示文摘结果接种子孢子的鸡胚中,抗球虫活力及其毒性的滴度:对于化合物毒性的中止点取决于处理的时间和化合物的化学性质,聚醚类抗生素(球安、盐霉素和莫能霉素)每胚50~100μg是有活力的。然而,这个浓度范围对鸡胚毒也很大。大多数药物在感染时(0天)注射入鸡胚或在感染后的第一天注入胚内,有相当好的抗球虫活力。药物的毒性点常常接近于对抗球虫活力的滴度。 | 谢明权 F.Fukata J.M.Gilbert L.R.McDougald 吴惠贤 | 1992 | 畜牧兽医科技1992，，1： | 1 |
