The first method used not only the row element but also the column element of covariance matrix to structure a toeplitz matrix; this process accomplishes the function of forward/backward spatial smoothing for multipath signals.

第一种改进的方法不但利用了阵列输出协方差矩阵的行元素，而且还利用了阵列输出协方差矩阵的列元素构造Toeplitz矩阵，实现了前、后向空间平滑解相干的功能。

After studying this phenomenon, the author finds that, the covariance matrix of the complex expressions of horizontal gradients of the disturbing gravity field elements has a structure of blockwise repetitive Toeplitz matrix, though the covariance within the disturbing gravity field elements is still anisotropic. Therefore, the collocation problem of the complex combination of horizontal components is similar to that of gravity anomaly, which makes the degradation be able to be completed by FFT transformation matrix.

作者研究发现，利用水平梯度的复组合，即复数表示后，扰动重力场元复组合之间的协方差函数尽管还是各向异性，但它们对应的协方差矩阵却具有分块 Toeplitz 循环阵的结构，因而水平分量复组合的配置问题与重力异常的配置问题相似，可以利用傅立叶变换矩阵进行降阶处理。

With fixed size of data table, computational speedup factor increases with increament of tolerance error. With same tolerance error, speedup factor of node deletion approach is higher than that of global deletion.

当数据表数据容量一定时，计算的加速比随控制容差的增加而增加，在相同的容差条件下，节点删除算法比整体删除算法加速效果明显。

The result indicated that suitable thickness of paddy soil is about 15cm,and for dry arable land it should not be lower than 20cm;The alluvial rivers parent material is the best one to influent the output,the rice fields is the worst with the parent material of slate ground,while the dry and plough land is the worst for its purple sand shale parent material;The paddy rice is best with the acid soil,and the dry crop is the best with the neutral soil;The obstacles horizon exist in 35.2%of the rice fields in research region,and many for middle or top digit obstacles.

结果表明，水稻土的适宜耕层厚度为15 cm左右，旱耕地适宜耕层厚度应不低于20cm；成土母质对产量的影响以河湖沉积物母质最好，稻田以板页岩母质最差，旱耕地以紫色砂页岩母质最差；水稻以酸性土最好，旱作以中性土最好；研究区稻田有35.2%的存在障碍层，且多为中、高位障碍，是影响水稻产量整体提高的主要因素；水稻和旱作都以壤土为最好，其中，稻作怕砂，旱作怕粘；水稻土适宜的容重为1.00—1.29 g/cm~3。

We study the relation between topological sigma models and generalized geometries. The existence conditions for the most general type of topological sigma models obtained from twisting the N=(2,2) supersymmetric sigma model are investigated, and are found to be related to twisted generalized Calabi-Yau structures. The properties of these topological sigma models are analyzed in detail. The observa....

六标准差从1987年在摩托罗拉公司推行至今，已近20个年头，从一开始制造面的改善，延伸到非制造性的企业流程当中，它不但有效地变化员工能力与态度，也为企业带来突破性的营运改善，全方位提升企业竞争力；但事实上，六标准差管理活动导入对企业是一大变革性的挑战，因为其中牵涉策略、组织。。。。
