Firstly, it studies the definition of implication and its classification, basing on this, deeply analyzes the relations between implication and the connective "if, then" universally used in our ordinary life. Then the article points out that implication is logical abstract to the connective "If, then" used in the natural language. However, because of different understanding and mastering to it, implication may have different classification, it can't be given a right definition. We must master it by all kinds of concrete implications. According to different criterion, implication has different categories. This article mainly discusses its classification from two sides: Ancient Greece and Medieval's and metalogic's.
首先,论文简要地考察了蕴涵概念的界定,指出蕴涵是对自然语言中连接词"如果,则"的逻辑抽象,而对它的意义的不同理解和把握,则可以有不同种类的蕴涵,不能笼而统之地对蕴涵下一定义,只有通过各种具体蕴涵去掌握有关蕴涵的理论;依据不同的分类标准,蕴涵可以有不同的类型,本文主要讨论古希腊及中世纪对蕴涵所作的分类及从记号学这一元逻辑的角度出发对蕴涵作的分类。

Culture tender leaves in culture medium of MS+2,4-D1.5mg/L+30g/L suger+0.7% agar pH5.8 for 20 days in darkness at 25℃, and then subculture to induced Ⅱ-type calli. Use forceps cutting the tissue to nubble with 2mm2, and put the tissue into Agrodacterium tumefaciens LBA4404 liquid supplemented with AS 100mg/L,then, co-culture 3 days, resume 7 days in MS+2,4-D1.5mg/L+30g/L suger+500mg/L cef, take to MS+2,4-D1.5mg/L+30g/L suger+100mg/L cef+10.0mg/L kanamycin culture 20 days in darkness. After that to make it polarize in MS+30g/L suger+100mg/L cef+10.0mg/L km. The percentage of km resistant callus was reached max after infection for 45 min, the average is 29.66%. Simultaneity, tender leave callus are infected 5 min by A. tumefaciens liquid in different negative pressure, and kept on 15 min in Agrodacterium tumefaciens liquid without negative pressure. Then screen out resistant callus and obtain transgenic plants. When the negative pressure is -0.05MP the percentage of km resistant callus was reached max, the average rate is 37.5%.

Firstly, the random walk problem is introduced and the solution is schemed out theoretically. And then, the equivalent RC circuit for thermal analysis is discussed as the IC package is divided into many small blocks at the desired level of granularity. The techniques of analyzing the equivalent RC network by random walk algorithm are then discussed. At the same time, an equivalent model for thermal analysis is set up according to an IC chip. The proposed method is then applied to this model for both steady and transient analysis. Two speedup strategies, pseudo parallel walking and walk results reuse, are proposed sequentially to improve the algorithm performance.

First we construct a covariance matrix from sample images, then compute the eigenvalues and corresponding eigenvectors of the covariance matrix, construct a feature matrix with the eigenvectors. Then every images in database can be projected into the feature matrix and gain a projection vector, so does the input image. Then we can judge the resemblance between input image with each image in database by computing the distance between their projection vectors.
我们首先根据采集的样本图像构造一个协方差矩阵,然后求取该矩阵的特征值,以这些矩阵特征值对应的特征向量构造出一个特征空间,然后将输入图像向该特征空间映射,将获取的映射系数与样本库中图像的映射系数进行距离计算,根据计算出的距离判定输入图像与样本图像间的匹配程度。
