In chapter 2, the paper considers about applying the regularized method with a variance uniformization constraint to image restoration, therefore we discusses the relation between the variance of the restored image and the singular value of the discrete matrix of the blur operator in detail, and theoretically proves the well-posedness of the regularized method with a variance uniformization constraint.

在第二章中，本文考虑将带一致方差约束的正则化方法应用于图像的恢复，为此详细讨论了恢复图像的方差与模糊算子的离散矩阵的奇异值之间的关系，并从理论上证明了带一致方差约束的正则化方法的适定性。

电动汽车电子差速系统中的左轮定义为基准轮，右轮定义为差动轮，控制基准轮转速是为了控制电动汽车的运行速度，控制差动轮转速是为了减小电动汽车转向时汽车车轮的滑动摩擦，尽量使电动汽车车轮运行在纯滚动状态。

The prediction error series of the chain is a zero mean whiteGaussian series whose variance is equal to its prediction period. This property of the variance offersan effective way of reducing the variance of the prediction error series and acquiring excellent andstable performance of predictive data compression.

Methods 1038 eyes of 606 consecutive myopic patiences who had bilateral Custom Vue LASIK between March 2006 and August 2006 were involved in the study. Wavefront measurement and iris registration were performed in the upright position with Wavescan aberrometer, then more over iris registrations were performed in the supine positon during the operation with VISX Star S4 IR.

Meanwhile, result comes out that seven fossil samples are mostly evergreen Araucarioxylon, deciduous species prapably exists, but their fixed numbers of growing year are extraordinarily variant; Analysis of ariance indicates that, imposing ray cells, radial tracheid diameters-, the ratios of ray cells to radial tracheid diameters on distinguishing seven samples is doable as a whole, while not fitting for individuals.

经方差分析可以看出，利用射线直径、管胞直径和射线管胞比可以在总体上区分各标本，但对个别样本不适用；射线高度这一性状在各标本间差别很小，不能区分；结果认为：标本2和标本6的性状最相近，为相同的种类；标本1、4、7可能为同一属；对方差和CSDM曲线的综合分析认为，标本1、3、6的生长年限存在一定的区别，可能导致在方差分析上出现些许误差。

The ionomer membrane under the conditions of 20℃ and 0.05 MPa shows better permeaselectivities that the permeability coefficient of CO_2 and CO_2/ N_2 separation factor are 223 Barrer and 65.70, respectively, while CO_2 / CH_4 separation factor is only 14.70. An obvious increase in P_(CO_2) with decreasing pressure difference exhibits a characteristic of facilitated CO_2 transport, which is not disappear and almost unchange after two months. There is no this behavior for N_2 and CH_4. Hence, P_(CO_2) and α_(CO_2/N_2) and α_(CO_2/CH_4) can be enhanced simultaneously.

该离聚体膜显示出良好的CO_2渗透性能，在20℃和0.05MPa压差下，CO_2渗透系数P_(CO_2)和CO_2/N_2分离系数αCO_2/N_2分别高达223 Barrer和65.70.P_(CO_2)和αCO_2/N_2随CO_2压差的降低而明显增大，显示出促进输送特征，这一行为即使在膜放置2个月之后并不消失，渗透分离性能变化不大。N_2和CH_4无此性能，因此在气体压差较低时，P_(CO_2)和αCO_2/N_2、αCO_2/CH_4可同时提高。
