The thermal conduc tivities of about twenty species of trees were calculated by means of the expres sions and compared with its experimental values under the same condition. The av erage relative error is about 5%, so the calculation result is satisfactory.展开更多

Our main focus in this paper is on the social sciences. We propose a quadrant of different cultural–scientific stances from which the study of social phenomena is possible, based on the emic–etic dimension pertaining to the study of culture from contrasting perspectives. Although the emic–etic distinction is normal y applied in fields within the science of culture, it is proposed here that the distinction is in some ways germane to scientific practice in general, making it amenable for use in a culture of science(CoS) programme. The four perspectives that emerge from the quadrant are illustrated using exemplars. Different aspects of CoS—that is, scientific practice, scientific conventions and representations of science—are then discussed in further detail, including in two tables illustrating points of convergence and divergence between the East and West when it comes to different aspects of CoS.展开更多

The results showed that the variations of earliness in maturity, high 1000-grain weight, plant height and grain weight per spike were heritable and tended to be stable in IE3 and completely stable in IE4 The wide variation of main agronomic characteristics induced by embryo culture in vitro provided the probability of selection in wheat improvement. Some somaclonal lines with useful variations could be used directly in wheat production.展开更多
