ABSTRACT Code Division Multiple Access is the preferred multiple accessing mode of the Third Generation Mobile Communication Systems, but the inherent multiple-access interference limits its capacity.

码分多址是第三代移动通信系统的优选多址工作方案，但CDMA固有的多址干扰问题限制着系统的容量。

A multi-channel representation of the input image was obtained by a bank of Gabor filters, corresponding to multiple scales and multiple orientations. Full-wave rectification of each channel and contrast gain control among the channels were performed sequentially to get orientation feature maps with multiple scales and multiple orientations.

从输入图像出发，采用Gabor算子建立多尺度、多方位的多通道图像，通过全波整流和各通道间的对比度增益控制，得到多尺度、多方位的方位特征图，这些特征图的线性组合则为显著性图。

In real flight, multiple sensors of aircraft engine control system may fault at a time. In order to solve this problem, a revised multiple-failure-hypothesis based testing is investigated. This approach uses multiple Kalman filters, and each of Kalman filter is designed based on a specific hypothesis for detecting specific sensors fault, and then uses WSSR (Weighted Sum of Squared Residual) to deal with Kalman filter residuals, and residual signals are compared with threshold in order to make fault detection decisions. The simulation results show that the proposed method can be used to detect multiple sensors soft failures fast and accurately.

一般认为两个以上传感器同时发生故障的概率较小，但实际上不能排除其发生的可能性；提出了一种改进的多重故障假设方法来解决航空发动机控制系统多传感器同时发生软故障的问题，这一方法采用一组卡尔曼滤波器，每个滤波器对应一个被检测传感器的故障模态；采用残差加权二乘方处理滤波残差并与门限值作比较来判断是否发生故障；仿真结果表明，所提出的方法能有效解决多传感器软故障的检测与隔离问题。

The patho-factor of pulmonary fibrosis is very complex. With the development of cytobiology and molecular biology there are much proof shows PF is a disease induced by multiple factor, multiple organ and multiple cell; and happens between cells and mesenchyma in multiple path.

肺纤维化(pulmonary fibrosis，PF)形成的病理因素十分复杂，近几年细胞生物学和分子生物学的发展为PF的形成机制提供了大量依据，证明PF是一个多因素、多器官、多细胞、多种因子之间以及细胞与间质成分之间形成的一个多层次，多步骤，多通路的疾病。

It indicated that the multiple-layered films were mainly composed by C-F, C=C and Si-O bonging, a little Si-C and Si-F bonding were also existed because of history effect. The bondgap were calculated as 2.7eV. The dielectric constant of the multiple-layered films was close relative to the thickness of the covering layer-SiOx, so the thickness had better be reduce. The bonding configurations of multiple-layered films had no evident changes after 400癈 annealing, the thickness raise very little and the dielectric constant increase 8%. Compared with one-layered a-C:F films prepared in the same conditions, the SiOx/a-C:F/SiOx multiple-layered films had a better thermal stability.

结果表明，多层膜主要由C-F，C=C，Si-O键构成，由于器壁的历史效应，薄膜中还存在少量Si-C和Si-F键；多层膜的光学带隙经计算约为2.7eV；多层膜的介电常数与包层SiO_x厚度有很大关系，应尽可能减小SiO_x厚度；在经历200-400℃的N_2氛围中退火后，多层膜的红外结构没有发生太大的变化：膜厚度稍微增大，介电常数只增加了8％，与同样制备条件下沉积的单层a-C：F薄膜相比具有较好的热稳定性。

An optimum multiple strain and processing test condition for producing micro-ecological, multiple enzyme feedstuff from beer grain with solid state fermentation was selected by using analytic hierarchy process. Meanwhile, data dispose and weight analyses to the relevant relations of all factores effecting the selection of the scheme were done after setting up a matrix. Multiple weight value of scheme X in target were X1=0.26, X2=0.41,X3=0.33 respectively, so that the optimizing multiple strains and relevant processing conditions of beer grains solid state fermentation were obtained.
