The artificial boundary method is applied to solve three-dimensional exterior problems. Two kind of rotating ellipsoids are chosen as the artificial boundaries and the exact artificial boundary conditions are derived explicitly in terms of an infinite series. Then the well-posedness of the coupled variational problem is obtained. It is found that error estimates derived depend on the mesh size, truncation term and the location of the artificial boundary. Three numerical examples are presented to demonstrate the effectiveness and accuracy of the proposed method.

目的:了解原发性干燥综合征(pSS)相关继发免疫性血小板减少症(ITP)的发生率和临床特点。方法:回顾性收集498例pSS病人的临床资料及实验室检查结果,比较pSS继发ITP病人(观察组)和血小板计数正常病人(对照组)间临床表现、实验室检查及免疫学指标特征。结果:498例pSS病人中,有17.86%(89/498)病人继发ITP。与对照组比较,观察组病人表现出更高的疾病活动度、更低的补体C3水平(P<0.01)。此外,pSS继发ITP病人较少发生关节炎(15.8%vs 5.6%,P<0.05)及间质性肺病(16.5%vs 4.5%,P<0.05)。结论:继发性ITP是pSS病人常见并发症。其主要临床特点有更低的补体C3水平及更高的疾病活动度评分,而间质性肺病和关节炎的发生是继发ITP的独立保护因素。

为阐明秸秆纤维尺寸对真空脱水成型的育秧基质块干燥及吸水速率的影响,利用粗粉发酵磨浆(A),细粉发酵磨浆(B),细粉发酵(C)3种纤维处理工艺经真空脱水制备水稻育秧基质块,通过基质块中纤维尺寸频率分布、纤维与水分结合能,结合不同基质块孔隙度、干燥和吸水速率变化,拟合出育秧基质块的干燥及吸水模型。结果表明,磨浆和粉碎分别减小纤维直径和长度,基质块A的纤维长宽比最大为19.5,持水孔隙和总孔隙度分别达到85.66%和93.48%,纤维与水分结合能(XA=0.11 kg water/kg DS)显著优于其余纤维处理工艺。干燥动力学Logarithmic模型较优拟合出基质块水分损失速率,纤维长宽比最小的基质块C的水分干燥速率最快为0.29 kg/(kg·h),水分扩散系数最大为1.962×10^(-5)m^(2)/s,基质块C达到饱和含水率的时间最短为61.5 min,但饱和含水率数值最低为531.06%。综上所述,细分发酵工艺制备的纤维长宽比小的基质块干燥效率和吸水速率最优。
