碳载体的预处理对质子交换膜燃料电池催化剂的活性及耐久性有着至关重要的作用,本文介绍了燃料电池工作过程中碳载体的腐蚀机制,以及碳载体石墨化处理、酸处理、过氧化氢氧化、多元醇氧化等几种常见的预处理方式,指出了不同的预处理方式对碳载体抗的腐蚀能力、表面官能团性质、比表面积、催化剂活性及负载能力等物理化学性质的影响机制。结果表明,石墨化处理使得碳载体的有序结构增加,能够大大提高其在高电位下的抗腐蚀能力,但同时导致碳载体对催化剂的负载能力有所下降;而酸处理、氧化处理等方式可以有效提高碳载体对催化剂的负载能力,并通过协同效应提高催化剂的活性,缺点是碳载体的抗腐蚀能力稍弱。

吸烟者自我豁免信念对戒烟和吸烟行为有显著影响。以往研究使用认知失调理论解释吸烟者自我豁免信念的产生过程,这忽略了自我豁免信念的特殊性。吸烟者自我豁免信念的形成经过了认知失调和合理化、自我特殊性凸显以及信念竞争与稳固等三个过程。基于此,对吸烟者自我豁免信念的干预可采取伪善诱导干预、动机性访谈、问题式吸烟警示信息等措施。未来研究需结合我国吸烟者特点探究吸烟者自我豁免信念影响戒烟意愿的作用机制、形成过程的影响因素及有效干预措施。

为拓宽面齿轮的应用空间,结合面齿轮与弧线齿的特点,提出了偏置正交弧线齿面齿轮。根据坐标变换规律及啮合原理推导了全齿面的方程,并在Matlab软件中建立了全齿面模型。结合齿面模型及根切原理,利用Matlab软件编程计算了齿面根切的位置。借助CATIA软件二次开发进行仿真切齿试验,验证了计算的正确性。探究了各参数对最小内半径的影响,结果表明:坐标系距离与最小内半径呈负相关,刀具圆弧半径、偏置距离及模数都与最小内半径呈正相关,其中模数对根切位置影响最大。最后计算了顶尖位置,通过最大外半径与最小内半径之差确定了面齿轮的最大齿宽。
