摘要：目的:设计桡骨远端骨折夹板压力读取系统,以实现对夹板固定压力的实时监测。方法:该系统硬件由主控单元、压力温度采集单元和电源管理单元组成。其中,主控单元采用STC15系列的单片机作为主控芯片,压力温度采集单元选用FSR400薄膜型压力传感器和DS18B20数字温度测量芯片。系统软件采用C语言编写。在固定带上分别以与柳木夹板和3D打印夹板呈90°、60°、30°的方向施加载荷,负载总质量从600 g增加至1200 g。采用该系统测试夹板承受的压力大小及分布情况,每次测试重复6次。结果:该系统能够实时采集夹板的压力数值,并能通过显示屏显示。固定带分别与柳木夹板、3D打印夹板呈90°、60°、30°时,不同载荷下各传感器的最大压力均出现在固定带与夹板边缘连接处,夹板中间部分受到的压力相对较小。固定带在与柳木夹板呈90°、载荷1200 g时柳木夹板承受的压力最大,为(239.17±4.49)g;固定带在与柳木夹板呈60°、载荷600 g时柳木夹板承受的压力最小,为(89.83±17.38)g。固定带在与3D打印夹板呈90°、载荷1100 g时3D打印夹板承受的压力最大,为(177.67±21.77)g;固定带在与3D打印夹板呈30°、载荷600 g时3D打印夹板承受的压力最小,为(66.50±3.02)g。结论:该系统可及时读取夹板不同载荷、不同角度下受到的压力,且与柳木夹板相比,3D打印夹板上的压力分布更均匀。该研究可为临床夹板固定定量化治疗提供理论依据。

摘要：In computer aided geometric design(CAGD) ,it is often needed to produce a convexity-preserving interpolating curve according to the given planar data points. However,most existing pertinent methods cannot generate convexity-preserving in-terpolating transcendental curves;even constructing convexity-preserving interpolating polynomial curves,it is required to solve a system of equations or recur to a complicated iterative process. The method developed in this paper overcomes the above draw-backs. The basic idea is:first to construct a kind of trigonometric polynomial curves with a shape parameter,and interpolating trigonometric polynomial parametric curves with C2(or G1) continuity can be automatically generated without having to solve any system of equations or do any iterative computation. Then,the convexity of the constructed curves can be guaranteed by the appropriate value of the shape parameter. Performing the method is easy and fast,and the curvature distribution of the resulting interpolating curves is always well-proportioned. Several numerical examples are shown to substantiate that our algorithm is not only correct but also usable.

摘要：Electronic structures in two kinds of boron structures are investigated by the first-principle density func- tional theory （DFT） calculations. One structure is from theoretical prediction, and the other is from experimental in- vestigation. Binding energy calculations suggest that the boron structure designed from theory is more stable than that made by experiment. Elastic constants calculations show that both structures are mechanically stable. The electronic structure results show that the theoretical designed structure exhibits semi-metal behavior, while the other structure exhibits metMlic character. No magnetic phenomenal is discovered from them. All the calculations are carried out by the first principles calculation through the MatC1oud platform, which is developed by our research group.
