This paper presents a new calculation method that can calculate the load distribution on pipe threaded connections under tension load. On the basis of elastic mechanics, the new method was developed by analyzing each thread tooth, and a new deformation and covariant equation by making a mechanics analysis on each thread tooth was obtained. Compared with the traditional method proposed by the previous references, the new deformation and covariant equation could be used to describe the relation between the previous and the next thread tooth. By applying the new method on the sample of P-110S pipe threaded connection, the obtained results show that the load on thread tooth mainly concentrates on the four or five threads engaged and the middle teeth were not utilized well to bear the loads. The model offers a new way to calculate the loads carried on the thread teeth under tension load.

既有商品住宅节能改造具有一定程度的外部性,阻碍了节能改造的深入开展。通过分析节能改造外部性的产生原因和外部性表现,建立外部性测算方法,为外部性内部化,构建节能改造外部性偿还机制提供必要依据。采用经济学理论与方法对既有商品住宅节能改造外部性的产生和表现等进行了分析,在识别外部性供体与受体的基础上,提出了节能改造外部性的测算方法。通过案例分析论证了外部性测算方法的适用性。结果表明,应减轻或消除外部性对节能改造的影响,采取必要手段将节能改造外部性内部化,构建统一的节能改造外部性测算方法,建立节能改造外部性偿还与节能量交易机制。

从炸药装药的瞬时爆轰产物飞散理论出发,根据动量守恒原理得出药型罩装药形成爆炸成型弹丸的速度计算模型,并根据装药高度与直径之比对弹丸速度的影响修正了计算模型。应用该计算模型计算了大锥角药形罩和球缺药型罩装药形成的爆炸成型弹丸速度,计算结果与实验和数值模拟得到的结果吻合较好,此速度计算模型适合于工程应用。
