修辞与语法的界限

本文以几种类型的定中短语为对象 ,分析研究了在语义组合上 ,修辞手段与语法手段的区别 ,指出 ,语法关系与语义关系的不对应 ,是现代汉语的特点 ,在分析语法结构时 ,如果不认识或者忽略这个特点 ,片面地从语法关系的角度去考察语义关系 ,就会作出不符合语言运用实际的分析。本文着重分析了形容词做定语的 ,具有语法关系与语义关系不对应特征的定中短语 ,对其类型、语义组合方式、构成条件作了分析研究     

Three dimensional couette flow and heat transfer through a porous medium with variable permeability

This paper reports research on the effects of variations in injection velocity and permeability on the heat transfer and flow through a highly porous medium between two horizontal parallel plates situated at constant distance with constant suction by the upper plate. Due to this type of variation in injection velocity and in permeability the flow becomes three dimensional. The governing equations are solved by adopting complex variable notations to obtain the expressions for the velocity and temperature field. The skin-friction along the main flow direction and rate of heat transfer are discussed with the help of graphs.

Effects of light and temperature conditions on flowering in Mat Rush

The effects of photoperiod and light intensity on flowering in Mat Rush cv. Gangshan 3 were studied. The results showed that treatments with longer day length stimulated flowering significantly and increased stem flowering percentage (SFP). Plants treated with low light intensity at early stage had substantially reduced florets per cyme, SFP, tillers per plant and stem length. At middle and late stage, low light intensity significantly reduced SFP. The principal climatic factors affecting SFP were as follows: mean temperatures (MT) of the third ten-day period (TDP) in December and of the second TDP in February, actual sunlight hours (SH) of the third TDP in February and precipitation of the third TDP in March. A nonlinear simulation model for SFP was established with experimental results and corresponding climatic data (see Eq. (2)). Simulation by the above equation yielded values the same as those observed from 1992 to 2000, indicating its accuracy in describing the relationship between flowering and light and temperature conditions. The interaction between vernalization and SH is also discussed in this paper. Project (No. 981105) supported by the Ningbo City Science Foundation, China
