与常规壁厚螺杆钻具相比,等壁厚螺杆钻具以其输出功率大,输出扭矩稳定等优点获得业内认可。随着等壁厚螺杆钻具的逐步推广使用,等壁厚橡胶衬套失效问题也日益突出。橡胶衬套失效以后,螺杆钻具输出性能降低,使用寿命也减小,这对钻井速度和钻井效益都有较大影响。基于热力学原理、Principal strain疲劳算法,建立螺杆马达定转子数值模型,研究了井深、过盈量及粗糙度对橡胶衬套热力学行为的影响,并运用Fe-safe疲劳分析预测橡胶衬套寿命。研究结果表明,等壁厚橡胶衬套主要失效形式为疲劳失效;通过等壁厚与常规壁厚橡胶衬套对比分析可知,等壁厚橡胶衬套较常规壁厚橡胶衬套有更好的密封性能,且对静液柱压力敏感程度更低。对等壁厚橡胶衬套进行设计时,应重点考虑过盈量对橡胶衬套磨损的影响,以确保螺杆钻具安全高效工作。

目的总结378例尿道下裂的手术治疗经验。方法本组病例中,对阴茎头型者尽量采用尿道口前移阴茎头成型法(MAGPI术式);冠状沟型及阴茎体型尽可能的采用尿道板纵切卷管法(Snodgrass术式)或加盖岛状皮瓣法(Onlay术式);对有严重阴茎下弯,不离断尿道不能矫直者采用横裁或纵裁包皮岛状皮瓣尿道成型术(Duckett术式);对尿道缺损较长的阴囊型及会阴型用尿道口周围皮肤卷管加横裁包皮岛状皮瓣成型尿道(Duplay联合Duckett术式)。结果治愈344例,并发尿瘘34例。尿道狭窄78例经尿道扩张及留置导尿管均获痊愈。成功率91.0%。356例获得随访,平均随访时间18个月(3～38个月)随访期间患儿排尿正常。结论选择正确的手术方法,术中尽可能的保留尿道板,用带血管蒂的皮下筋膜覆盖尿道,熟练的操作技巧对提高手术成功率至关重要。对术后合并狭窄的患儿尽早行尿道扩张,留置导尿管是一种非常有效的方法。

企业志愿者已经成为中国公益事业的一支重要的新生力量,企业志愿行为会不会干扰企业的盈利是管理者和学术界都很关心的问题。本研究基于角色增益视角,构建了包括工具型增益和情感型增益的被调节的中介作用模型,并通过315份问卷进行了实证检验。结果表明,员工志愿行为对工作绩效有显著的正向影响;工具型增益和情感型增益在员工志愿行为和工作绩效之间起到部分中介作用;组织认同对情感型增益及其中介效应均起到增强型调节作用,但是对工具型增益及其中介效应没有起到调节作用。结论打消了企业雇主的顾虑,同时提醒管理者,高组织认同水平的员工参与志愿服务可以带来更多的积极情绪,进而提升工作绩效。研究有助于揭示了志愿服务作用于工作绩效的机理,促进企业志愿服务的发展。
