With the development of quantum computing technology, quantum public-key cryptography is gradually becoming an alternative to the existing classical public-key cryptography. This paper designs a quantum trapdoor one-way function via EPR pairs and quantum measurements. Based on this, a new quantum public-key cryptosystem is presented, which offers forward security,and can resist the chosen-plaintext attack and chosen-ciphertext attack. Compared with the existing quantum public-key cryptos,eavesdropping can be automatically detected in this new quantum public-key cryptosystem under a necessary condition, which is also detailed in the paper.

目的探讨门静脉动脉化在肝门部血管重建中的作用。方法对6例侵犯肝动脉的围肝门区恶性肿瘤,均行联合肝叶切除的根治性手术,并联合对受侵的肝动脉切除,并行门静脉与肝动脉近端合适部位的吻合,完成门静脉动脉化处理。结果本组病例围手术期无死亡及肝功能衰竭的发生。术后病理根治性切除率为100%。术后观察6个月以上,未见门脉高压和肝损害的出现。结论在肝动脉受肿瘤侵犯被迫切除时,根据剩余肝体积的多少,选择合适的肝动脉口径行门静脉动脉化,不失是一种保留肝动脉血供的方法。不仅可以提高手术的切除率,而且可降低术后并发症的发生率。

针对我国某铀矿尾库的风险评估需求,根据具体场地的水文地质条件,建立了包气带及饱和带中核素迁移的数学模型。在理论建模基础上,基于广义积分变换法对核素迁移方程进行求解,分析了铀尾矿库中^(238) U、^(234) U、^(230) Th、^(226) Ra、^(210) Pb在4种情景下的迁移规律。结果表明:广义积分变换法对于评估相对较复杂的地下污染物运移问题效果较好,尤其对于长时间尺度和污染物浓度非常小的情况,结果准确。进一步验证了较厚的包气带不仅能最低程度上减小核素在饱和带的迁移速率,而且浓度也低。吸附性能越强的介质,对核素迁移的阻滞作用越大。

In order to predict accurately the characteristics of supersonic flow in new type externally pressurized spherical air bearings under large bearing clearance and high air supply pressure, which could decrease their load carrying capacity and stability, a CFD-based analysis was introduced to solve the three-dimensional turbulent complete compressible air flow governing equations. The realizable κ-ε model was used as a turbulent closure illustrate that the interaction exists between shock waves The supersonic flow field near air inlets was analyzed. The flow structures and boundary layer, and the flow separation is formed at the lower comer and the lower wall around the point of a maximum velocity. The numerical results show that the conversion from supersonic flow to subsonic flow in spherical air bearing occurs through a shock region （pseudo-shock）, and the viscous boundary layer results in the flow separation and reverse flow near the shock. The calculation results basically agree with the corresponding experimental data.
