哈耶克的自由法治观及其对构建社会主义和谐社会的启示

作为当代西方自由主义大师，哈耶克坚持自由即个人自由。在自由法治观上，他坚持“法治下的自由”，即“自由是以法治为基础的”。深入学习研究哈耶克的自由法治观对于我国构建社会主义和谐社会有着重要的借鉴价值和启示意义。

Visible region extraction from a sequence of rational Bézier surfaces

A method for computing the visible regions of free-form surfaces is proposed in this paper. Our work is focused on accurately calculating the visible regions of the sequenced rational Bézier surfaces forming a solid model and having coincident edges but no inner-intersection among them. The proposed method calculates the silhouettes of the surfaces without tessellating them into triangle meshes commonly used in previous methods so that arbitrary precision can be obtained. The computed silhouettes of visible surfaces are projected onto a plane orthogonal to the parallel light. Then their spatial relationship is applied to calculate the boundaries of mutual-occlusion regions. As the connectivity of the surfaces on the solid model is taken into account, a surface clustering technique is also employed and the mutual-occlusion calculation is accelerated. Experimental results showed that our method is efficient and robust, and can also handle complex shapes with arbitrary precision.

Simple model for gas holdup and liquid velocity of annular photocatalytic external-loop airlift reactor under both bubble and developing slug flow

Based on the momentum conservation approach, a theoretical model was developed to predict the superficial liquid velocity, and a correlation equation was established to calculate the gas holdup of an annular external- loop airlift reactor(AELAR)in the bubble flow and developing slug flow pattern. Experiments were performed by using tap-water and silicone oil with the viscosity of 2.0 mm²/s(2cs-SiO)and 5.0 mm²/s(5cs-SiO)as liquid phases. The effects of liquid viscosity and flow pattern on the AELAR performance were investigated. The predictions of the proposed model were in good agreement with the experimental results of the AELAR. In addition, the comparison of the experimental results shows that the proposed model has good accuracy and could be used to predict the gas holdup and liquid velocity of an AELAR operating in bubble and developing flow pattern.     

二三十年代农村合作社借贷资金的构成及其来源——20世纪前期中国乡村社会变迁研究

在二三十年代出现的农村合作运动，被认为是“救治农村”的有效方法之一，但是，从合作社借贷资金的来源与构成状况上，我们可以看到合作社的社内资金极其微小，转而不得不依赖于社外资金，而社外资金对于农村合作社的支撑又极不稳定，从而无法保障农村合作乃至农村经济的复苏，这从一个侧面反映了当时中国乡村社会变迁的实况。
