Five F 2 segregation populations, derived from crosses between the susceptible japonica cultivars (cvs.) Kongyu131 and donor cvs. Aichi Asahi (AA), BL1, Digu, Pai-kan-tao (PKT) and Oryzica Llanos 5 (ORL5), were used to evaluate their natural resistance to blast in cold region. The field test of their blast resistance was conducted in 858 Farm, which showed that Aichi Asahi, BL1and Digu were...
Network teaching as a new teaching methods, taking full advantage of computer, networking and multimedia technologies, making teaching behaviors across time and space constraints, has a great deal of flexibility and interactivity. How to achieve better learners constructing their own knowledge is the network teaching platform problems based on the characteristics of the network. Based on the development...
Advanced manufacturing technology has not only the technology advanced facet but also the conceptuality advanced facet, according to this principle idea, the paper pointed out that quality cost must be re-identification under the concept of "reasonable quality". A relative perfect quality cost management evaluating system conformed to AME requirements must be constructed and quality cost...
Quality data collection processes and process parameters adjustment is the key element of Quality control processes. The content of process quality data collection and control include process monitoring and product quality testing. Process parameter monitoring can be achieved by measuring the characteristics of the related parameters. Process product quality testing can be achieved by direct measuring...
This paper analyse the age makeup of oratosquillaorator age at dalian sea entrance by use of the clustering method. According to sample and test, the distance between the old genuses and the new genuses is computed according to the clustering method of the most short distance by use of range criterion formulation and the absolute value distance formulation , and the clustering matrix is obtained....
