Samara a nut or achene whose pericarp is extended to form a wing for wind dispersal, e. g. ash ( fraxinus excelsior )
翅果：指堅果或瘦果中果皮延伸成翼狀，以利於風媒傳播的果實類型。如白蠟樹的果實（歐洲白蠟樹） 。Secondly, the temperature distribution in rib - tube heat exchanger in the course of heat transfer is programed and simulated using apdl language of fem software ansys, and the average convection coefficient of both sides is obtained. the rib - tubes with different structure are also simulated and optimized on the base of the calculated results, the relationship between structure and the average convection coefficient of both sides is summrized. the rib - tube structure is optimized using apdl. finally, combines numerical simulation with experimental research, and results of numerical simulation are found to be close to the experimental data
利用ansys有限元程序對翅片管換熱器的換熱過程進行數值模擬，確定了換熱過程中翅片管的溫度場和熱流量梯度分佈狀況，對翅片管換熱器的多組分流場進行計算，給出了逆流和順流兩種情形下翅片管結構參數對換熱效果的影響規律，並利用ansys提供的優化技術編寫程序對翅片管進行結構優化設計，為其今後在工業中的設計及使用提供了重要依據。Furthermore, the strategies for protection of e. mollis are discussed in this paper
此外，針對翅果油樹的瀕危現狀和原因，還提出了科學保護對策。
