A reciprocal theorem of dynamics for potential flow problems is first derived by means of the Laplace transform in which the compressibility of water is taken into account. Based on this theorem, the corresponding time-space boundary integral equation: is obtained. Then, a set of time domain boundary element equations with recurrence form is immediately formulated through discretization in both time and boundary. After having carried out the numerical calculation two solutions are found in which a rigid semicircular cylinder and a rigid wedge with infinite length suffer normal impact on the surface of a half-space fluid. The results show that the present method is more efficient than the previous ones.

Based on the dynamic governing equation of propagating buckle on a beam on a nonlinear elastic foundation, this paper deals with an important problem of buckle arrest by combining the FEM with a time integration technique. A new conclusion completely different from that by the quasi-static analysis about the buckle arrestor design is drawn. This shows that the inertia of the beam cannot be ignored in the analysis under consideration, especially when the buckle propagation is suddenly stopped by the arrestors.

目的:评价聚丙交酯乙交酯含肝素涂层的血液相容性。方法:实验于2006-05/06在大连理工大学材料学院完成。采用浸涂法在316L不锈钢表面制备了聚丙交酯乙交酯含肝素涂层,通过血小板黏附实验,对其血液相容性进行了初步评价,测定了水和甘油在各样本表面的接触角,由此计算出表面张力、界面自由能、黏附功等表面能量参数,分析了其对血液相容性的影响。结果:①聚丙交酯乙交酯涂层、含肝素2%和含肝素5%的聚丙交酯乙交酯涂层的接触角分别为78.5°、81.5°和83°;含肝素涂层的表面张力、界面自由能和黏附功均有所降低。②聚丙交酯乙交酯涂层表面黏附血小板较多,个别血小板变形伸出伪足;含肝素的聚丙交酯乙交酯涂层血小板黏附量较少,未发生变形、聚集,而且随着肝素含量的增加血小板黏附量减少。结论:聚丙交酯乙交酯含肝素涂层后血液相容性明显改善。

目的分析游离腹部皮瓣乳房重建术中机会性内乳淋巴结活检的情况，探讨内乳淋巴结检出及转移的相关因素。方法收集2006年11月至2015年12月，以内乳血管作为受区血管的游离腹部皮瓣乳房重建术乳腺癌患者的临床资料，分析内乳淋巴结的检出率和阳性率，分析影响内乳淋巴结检出和转移的相关因素。结果113例游离腹部皮瓣乳房重建术中，共有53例乳腺癌检出内乳淋巴结，内乳淋巴结检出率为46．9％。即刻重建患者中，内乳淋巴结转移4例。检出内乳淋巴结的患者中，内乳淋巴结转移阳性率为7．5％（4／53））。Logistic多因素分析显示，肿瘤最大径、肿瘤位置和腋窝淋巴结状态与内乳淋巴结转移均无关（均P〉0．05）。结论乳腺癌患者腹部游离皮瓣重建术中，可以通过机会性内乳淋巴结活检的方法评估内乳淋巴结转移状态，检出率较高，且无需额外手术操作。腋窝淋巴结转移和肿瘤最大径可能为内乳淋巴结转移的高危因素。
