Numerical study of soil-rock mixture:Generation of random aggregate structure

The soil-rock mixture(SRM) is highly heterogeneous. Before carrying out numerical analysis,a structure model should be generated. A reliable way to obtain such structure is by generating random aggregate structure based on random sequential addition(RSA). The classical RSA is neither efficient nor robust since valid positions to place new inclusions are formulated by trial, which involves repetitive overlapping tests. In this paper, the algorithm of Entrance block between block A and B(EAB)is synergized with background mesh to redesign RSA so that permissible positions to place new inclusions can be predicted,resulting in dramatic improvement in efficiency and robustness.

System Architecture of Godson-3 Multi-Core Processors

Godson-3 is the latest generation of Godson microprocessor family. It takes a scalable multi-core architecture with hardware support for accelerating applications including X86 emulation and signal processing. This paper introduces the system architecture of Godson-3 from various aspects including system scalability, organization of memory hierarchy, network-on-chip, inter-chip connection and I/O subsystem.

静脉性阳萎的阴茎海绵体造影诊断

报导６８例经手术证实静脉性阳萎病人的阴茎海绵体造影情况，并对其征象进行讨论。经筛选后６８例２３～６２岁阳萎患者，注入我院自制复方罂粟碱，行阴茎海绵体造影，患者均有不同程度静脉漏，分为４型，深静脉型、浅静脉型、混合交通型和异常血管型。结果证实海绵体造影是静脉性阳萎的有效检查方法，除可指导手术方案外，还可检查手术效果。

改良反汤氏位对颧弓骨折诊断及辐射防护价值的探讨

对２１例临床拟诊颧弓骨折的外伤患者进行常规颧弓轴位及改良反汤氏位投照，并用ＲＧＤ＿３型热释光剂量仪对其中６例患者颜面部Ｘ线辐射剂量进行了测试。结果：两种投照位置照片，对颧弓骨折诊断的阳性率相同，但对骨折线及骨折错位程度的显示，后者优于前者。在患者颜面部接受Ｘ线辐射剂量上，改良反汤氏位约低于常规颧弓轴位的１９～２３倍。在投照方法学上，改良反汤氏位简便，易行，医患双方均易接受。

妇科腹腔镜检100例分析

应用电视腹腔镜技术施行妇科诊断手术１００例，包括不孕症、腹痛原因不明、盆腔包块性质不明、宫外孕的诊断和治疗、绝育手术及术后评估等。结果表明，利用电视腹腔镜进行妇科疾病的诊断，具有时间短、损伤小，尤其是在不孕症病因诊断中起着重要的作用。
