The author takes these rhetoric figures of parallelism,rhetorical repetition,ellipsis in English and Chinese as examples to have a primary contrastive analysis,which makes known that they can not only beautify words,but also function as cohesion or coherence of a text.

Its language is characterized by the alternate use of rhyme and prose,the embellishment of slang and ballad,skillful use of serious and funny argot,proper use of vivid analogy,expert use of parallelism,and numerous quotes of classics to support his views.

This paper presents a study on the characteristics of sediment transport and sediment delivery ratio in the lower Yellow River based on data of runoff and sediment load measured from 1950 to 2002.

The paper puts forward the relational expression of sediment delivery ratio of the whole section and section by section of the lower reaches based on silt-discharge data of each flood occurred in the lower Yellow River and on the operational conditions of late period of debris retaining of the Xiaolangdi Reservoir.

Based on ASME PTC6 Turbine Performance Acceptance Test Code,the principle of calculating the specific enthalpy of exhaust steam from low-pressure(LP) cylinder has been determined.

Owing to certain limitation of existing model for calculating the specific enthalpy of exhaust steam from final stage of steam turbine,a modified radial basis network model has been established,which can be used for calculating the specific enthalpy value of exhaust steam from steam turbines.

The results of model and prototype experimentals made known that this type of grit chamber noting for not only the higher drainage sand ratio, the lower water and sand ratio,but also suitable for the economic: inverstment and wide applicable conditions.

The factors of affecting critical ratio of irrigation to drainage and the method of determining critical ratio of irrigation to drainage are also discussed profoundly.
