For general engineering problems, the analytical transformation rules are sufficiently accurate to design the similar cascade profile, but further improvement of the precision is limited by the one-dimensional assumption of the transformation, therefore an inverse blade design method—influence matrix method, based upon the surface vorticity model, is developed to improve the precision effectively.
进一步讨论了在具有相同表面压力系数分布的情形下,进口马赫数对附面层发展的影响,发现在一定条件下,只要表面压力系数的分布相似,则叶面附面层发展情况及无量纲气动力参数也将存在相同精度的相似,这一结论使我们在进行相似流场模拟的模型设计中,得以只进行无粘流场之间的相似变换,从而大大减少相似模型设计的工作量和复杂性。

Lanthanides belong to the sixth cycle of the periodic table Ⅲ B family, are all solid metal, they are La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, holmium, erbium, thulium, ytterbium, and lutetium were 15 kinds of metals and their periphery are two layers of electronic 5d16s2, while the peripheral third layer f orbital but never zero to 14, so the external electronic structure of 4f0-145d16s2, and therefore these elements in oxidation number are to 3, very close chemical properties, extraction, when it is difficult to separate them they are mostly multi-element mineral mix, more difficult to increase refining, and their atomic number of 57-71, one by one to increase the number of protons the nucleus, and thus extranuclear electron of gravity is also growing, so that atomic radius decreases with increasing atomic number Z, which makes lanthanides contraction, ionic radius is also reduced, which also makes Zr, Hf, Nb and Ta, Mo and W, the atom and ionic radius very close to each other they also determine a similar nature, resulting in difficult separation, also the tribe Ⅷ of the fifth cycle, ruthenium, rhodium, palladium, and the sixth cycle, osmium, iridium, platinum is very similar in nature, thus The six elements, said platinum group elements.
镧系元素属于周期表第六周期中ⅢB族,全部是固体金属,它们是镧、铈、镨、钕、钷、钐、铕、钆、铽、镝、钬、铒、铥、镱和镥共十五种金属元素,它们的外围两层的电子均是5d16s2,而外围第三层的f轨道电子却从零增加到14个,所以外围电子结构为4f0-145d16s2,而使这些元素氧化数均为+3,化学性质极为接近,提炼时很难分开,它们的矿石又大多是多种元素混在一起的,更增加提纯难度,它们的原子序数为57-71,核内质子数逐个增加,因而对核外电子引力也不断增强,使原子半径随原子序数Z增加而减小,这就使镧系元素收缩、离子半径也缩小,这也使得Zr和Hf,Nb和Ta、Mo和W等原子和离子半径都很接近、也决定了它们彼此性质类似,以致难以分离、也使第Ⅷ族中第五周期的钌、铑、钯和第六周期的锇、铱、铂在性质上极为相似,因而称这六个元素为铂系元素。

They share many similar or the same featutes with Archaeopteryx or other primitive birds, such as: U-shaped furcula, uncinate process, laterally facing glenoid of shoulder girdle, comparatively long forelimb, large semilunate carple, retroverted pubis, ascending process of astragalus, and "modern feathers"with rachis and barbs etc.

A generalized Gaussian Laplacian eigenmap algorithm based on geodesic distance is proposed,which incorporates geodesic distance and generalized Gaussian function into the original Laplacian eigenmap algorithm.GGLE algorithm can adjust the similarities between nodes of neighborhood graph,and can preserve the different degrees of local properties by using super-Gaussian function,Gaussian function or sub-Gaussian function.Moreover,GGLE can avoid the deficiency of Euclidean distance by using geodesic distance when neighborhoods of data points are enlarged for preserving more neighborhood relations.Experimental results show that the global low-dimensional coordinates obtained by GGLE have different clustering properties and different degrees of preserving local neighborhood structures when different generalized Gaussian functions are used to measuring the similarities between high-dimensional data points.(3) An ensemble-based discriminant algorithm based on GGLE is proposed.
该算法将测地线距离和广义高斯函数融合到传统的拉普拉斯特征映射算法中,可以调整近邻图结点间的相似度,通过选择超高斯、高斯或者次高斯函数来实现不同程度的近邻局部特性的保持;而且当需要保持更多的近邻关系使得数据点邻域增大时,采用测地线距离可以避免欧氏距离度量不合理的缺陷;实验结果表明在用不同的广义高斯函数度量高维数据点间的相似度时,局部近邻结构保持的程度是不同的,GGLE获得的全局低维坐标也呈现出不同的聚类特性。

The results show that TSN inhibits the delayed rectifying potassium current obviously when extracellularly applying 1×10〓g/ml TSN. The effect is dose-dependent and partial revisable. It develops slowly, and so does its recovering after washing. TSN also accelerates the inactivation of I〓, and this effect is much like that of Verapamil, Nifedipine and -Bay K 8644 on I〓 at NG108-15 cells. In addition, similar effects on I〓 are also observed when intracellularly applying TSN.
实验结果显示,细胞外施加1×10〓g/ml TSN明显降低I〓的幅度,作用呈量-效关系,部分可逆;TSN作用的出现和冲洗后的恢复过程都是缓慢的;TSN不但降低I〓的幅度而且还使之失活变快,这种效应同Verapamil、Nifedipine、-Bay K 8644对NG108-15细胞的I〓的作用相似;另外,将TSN施于细胞内,对I〓也有同胞外施加TSN相似的作用。

The intensity of pulse noisy pixels significantly differs from adjacent pixels of image. The de-noising will be accomplished by modifying the intensity of the noisy pixel according to the firing patterns of adjacent neurons of PCNN. At last, this dissertation suggests a new kind of filter for de-noising pulse noise based on the PCNN and median filter. It is very simple, and the simulation experiment of the image processing shows that the de-noising effect is much better than neighborhood averaging method and median filter.

Black→blacken,quick→quicken,soft→soften,hard→ harden 相似形容词多见的再有:mad, deep,thick,weak,dead,fat,flat,red,straight,moist,sharp,white,loose,short,dark,bright,coarse,fast,rough,fresh
等。在这些形容词后增加词缀-en时,red,flat,fat等词应先双写着末子音字母,再增加-en;white,wide等以字母-e结局的单词,增加后缀时,只需加字母-n;fast一词加后缀-en组成的动词 fasten,其含义为&使稳固&,而不是&加快&。
