Phosphorus doped（P-doped） nanogranular SiO2 films have been deposited by plasma-enhanced chemical vapor deposition. A high proton conductivity of;.2x10-4S/cm and a large electric double layer（EDL） capacitance of;.2μF/cm2 have been obtained. Flexible coplanar-gate EDL thin film transistors（TFTs） gated by P-doped nanogranular SiO2 films are self-assembled on plastic substrates at room temperature. Due to the big EDL capacitance,such TFTs show ultra-low voltage operation of 1 V,a large field-effect mobility of 18.9 cm2/Vs,a small subthreshold swing of 85 m V/decade and a high current on/off ratio of 107. Furthermore,the EDL TFT could work in dual coplanar gate mode. AND logic operation is realized. Our results demonstrate that such TFTs gated by P-doped nanogranular SiO2 films have potential applications in low-power flexible electronics.

.GN algorithm has high classification accuracy on community detection, but its time complexity is too high. In large scale network, the algorithm is lack of practical values. This paper puts forward an improved GN algorithm. The algorithm firstly get the network center nodes set, then use the shortest paths between center nodes and other nodes to calculate the edge betweenness, and then use incremental module degree as the algorithm terminates standard. Experiments show that, the new algorithm not only ensures accuracy of network community division, but also greatly reduced the time complexity, and improves the efficiency of community division.

三线阵CCD航天立体测绘相机的交会角稳定性是保证高精度立体测绘的关键指标,新一代测绘相机研制前,需要首先解决其稳定性标定的基础问题.本文提出一种采用高精度自准直经纬仪交会测量的标定方法,以解决多光学传感器复杂系统光轴交会角稳定性的高精度标定问题.该方法采用4台精度为0.5″的自准直经纬仪对测绘相机上的基准立方镜两个正交平面进行正倒镜自准测量,再进行正倒镜互瞄,通过多测回解算求得立方镜之间的转换矩阵.实验结果表明,该标定方法重复性精度0.5″,闭合环标定精度达到1″量级.实际标定结果表明测绘相机力学试验前后,交会角最大变化量为5.1″,满足稳定性小于10″的指标要求.

The dynamic design method is essentially the evolving processes of various information, it consists of dynamic design and information construction. It is a new technology of increasing popularity. Because of the particularity and complexity of the Qinghai-Tibet Railway construction, the technology of the dynamic design and information constructing was used tentatively. Based on processes of Qinghai-Tibet Railway construction, this paper discussed and analysed the idea of dynamic design and applications. Meanwhile in allusion to arisen problems in design and construction, some principles and suggestions of reinforced measurements were put forward. Though the works of construction and design are being carried through, good results have been obtained.

推导了分划板失调量与待测系统调制传递函数(MTF)下降之间的解析表达式,对光管和待测系统焦距比与分划板装调精度之间的数学关系进行仿真分析,发现焦距比为1,分划板轴向装调误差为0.0012mm引起的待测系统MTF下降为0.01。据此提出依据Zernike系数定量指导装调,采用数字干涉仪与平行光管、分划板构成干涉光路进行逐次迭代调整的方法。实验与数学分析均表明,上述方法可显著提升分划板装调精度,其引起的探测器离焦导致的MTF下降可控制在0.013。实验结果与理论值之间的偏差表明,环境扰动等不确定度对标定精度产生影响,在测试环境良好的条件下采用上述装调方法,使用焦距与待测光电系统焦距相当的平行光管就可满足高精度光学标定与装调的测试需求。
