Using flow sediment laden formula set by Hanqiwei and overyear runoff,sediment data,the sediment retaining prediction of Manwan reservoir is carried out.
The observed deltas are highly two-dimensional in planform, adopting palmated structures which retain throughout their evolution a high degree of mirror symmetry.
A method to ascertain airtightness of regulable refrigeratory, airtightness material selection and a way to made air retaining wall were discussed in this paper.
Counterfort retaining walls are optimized in the paper, using the optimum program, costs of different counterfort retaining wall parameters were calculated and based on the contrast analysis.
If conceptualism retains what is correct in universalism and in nominalism and conceptualism offers an adequate explanation of the phenomena under consideration, then it solves the problem.
During two cooling methods, whether tension stress or compression stress, the retained austenite in steel reduced with stress increasing, had become from massive to streak or filminess.
