本文利用三维经典系综模型研究了平行偏振三色场中He原子的非次序双电离.利用强度相同的1600 nm和800 nm脉冲组成驱动场,低强度的400 nm脉冲作为控制场.研究结果表明,第一次返回碰撞轨道、奇数次返回碰撞轨道(不含第一次返回碰撞)和偶数次返回碰撞轨道释放的电子对和离子分别处在电子关联动量谱和离子动量谱上的不同区域.通过改变控制场的相位,可以很好地控制不同返回次数碰撞轨道在双电离中的占比,进而实现对电子动量分布和离子动量分布的控制.另外,多次返回碰撞导致的双电离以碰撞电离机制为主,而第一次返回碰撞导致的双电离以碰撞激发电离机制为主,所以通过改变控制场的相位也能实现对双电离机制的调控.

Study on the mechanism and law of temperature,humidity and moisture content on the mechanical properties of molded fiber products

引用

Journal of Bioresources and Bioproducts 2024年第3期9卷 351-368页

作者： Zhiqiang Fu tong Zhao Hu Wang Jingyi Wei Haozhe liu Liying Duan Yan Wang Ruixiang Yan School of Light Industry Science and Engineering Tianjin University of Science and TechnologyTianjin 300457China Department of Transportation and Vehicle Engineering Tangshan UniversityTangshan 063000HebeiChina College of Mechanical Engineering Tianjin University of Science and TechnologyTianjin 300457China

The change of temperature, humidity and moisture content (MC) will lead to the change of mechanical properties of molded fiber products (MFP). However, it is difficult to decouple the effects of temperature, humidity and MC on the mechanical properties of MFP, and predict the mechanical properties of MFP during the use. In this study, the laws and mechanism of mechanical properties of MFP with ambient temperature, humidity and MC were studied. The results showed that the direct effect of temperature (20−70 °C) on mechanical properties of MFP was insignificant, and the mechanical properties of MFP were mainly changed by MC. The MC was related to ambient temperature and humidity, and the relationship between the three could be described by the modified Guggenheim-Anderson-de Boer (GAB) model (20−70 °C and 30 %–90 % relative humidity). With the increase of MC, the elastic modulus and fracture strain was increased and decreased linearly, the yield strength and failure strength were presented GaussAmp laws, and the failure strain was presented asymptotic regressed distribution law. Two fracture modes of MFP, brittle fracture and ductile fracture, were revealed by the scanning electron microscopy of the mesoscopic fiber structure of sugarcane bagasse molded fiber products. The mathematical models and the changes of fiber structure were verified by wheat straw molded fiber products and waste paper molded fiber products. This study was contributed to understand the effects and mechanism of the change of temperature, humidity and MC on the mechanical properties of MFP.
