摘要：在面源气体排放的测量过程中,不可避免地受到相邻田地气体排放干扰,又受到环境扰动的影响,影响气体检测的准确性。为了提高测量精度,研究了基于激光光谱检测的复合面源甲烷非均匀排放测量方法。通过多次自标定测量,减少了外部环境的干扰。设计了非均匀面源排放物检测系统,并提出了消除气体波动检测方法。首先进行了准确性验证试验,待测源a的标准差为0.17,待测源b的标准差为0.18;随后与光声光谱抽取式进行了对比试验,相关系数达到0.91;最后开展了外场实际的测量应用,对不同施肥方式造成的两个不均匀排放待测源进行监测,实现对多源不均匀排放的准确测量。它具有农业气体排放,环境气体检测等实用工程价值。

摘要：提出了一种用于单晶蓝宝石绿色加工的新型多糖结合剂磨具。设计了磨具的配方和制备工艺,研究了微波处理对多糖凝胶性能的影响。制作了磨具试样并对单晶蓝宝石进行了加工试验。研究发现,随着交联多糖比例的增加,多糖凝胶的结晶度降低。含有交联多糖的磨具试样具有较高的表面硬度。加工试验结果表明,采用这种新型磨具,蓝宝石晶片的表面质量得到了显著的改善。当磨具砂结比为2∶1时,材料去除率可达0.68μm/min,提高磨具砂结比可获得较好的自锐性能,但材料去除能力降低,磨具磨耗增大。初步验证了多糖材料作为磨具结合剂的有效性。

摘要：In order to break through the limitationof thelatitude/longitudegrid and hexagon grid, a new subdivision unit, Half-honeycomb Trapezoid, is proposed. Based on the summarization of the geometric properties and subdivision performance of Half-honeycomb Trapezoid, a new discrete global topographic grid system is established, and its compatibility with hexagonal grid is analyzed. At last, the visualization of multi-resolution global grid is achieved.

摘要：目的 应用权重配方法，从多药物多剂量中优选临床联合用药方案，并以一个定量设计的范例说明其可行性。方法 根据临床实际，虚拟药1，药2和药3联用治疗儿童缺铁性贫血2wk。各药分为5-6个剂量水平，再均匀分布到6个组，每组6例，即构成6个联用方案。测定治疗2，3，4wk时的血红蛋白升高值（△Hb)，以4WK的测定值作为指标，用权重配方法进行数据分析，优化联用剂量，经确定性试验证实，从而寻找出最优化方案。结果 药1和药2都是主药，但药1对联合药效（△Hb)的贡献值最大，其次是药2，而药3作用极弱，药1与药2间有较强的协同作用，药2和药3间有微弱的协同作用，但药3对药1对有拮抗作用。重新制定联合用药方案，经确定性试验证实，将药1和药2调整到允许的最大剂量，删除药3组成新的方案，同最大效应组比较，表明此联用方案的为一优化方案。结论 权重配方法能有效地分析临床试验中各药在组方中的地位，并据此调整剂量，构成新的方案，经配方优化检验，可定量设计临床联合用药方案。

摘要：Currently, 3D printing of the character dolls is a very practical application for the average person. But the model of doll which can be obtained is static so the posture of the doll is single. On the other hand, the modification of the model is very difficult to non-professions. This paper proposes an rapid generation method of character doll with rotatable limbs, which is through adding the sphere joint to the doll＇s model automatically. After the model is segmented by drawing a line interactively, the sphere joint is created based on the segmentation boundary through entity modeling method. Lastly the two models of the doll and the joint are composited and printed. Some doll＇s model are tested on the FDM（Fused Deposition Modeling） 3D printer using this process. The results are more interesting and the efficiency has been greatly improved compared with modifying the model manually.
