Based on experimental study on spring preservation by water recharge and source supply, it is suggested that water be diverted from the Wohushan Reservoir and the Yellow River for recharge of the Yufuhe River and the Yufuhe River be dammed, so that surface water will be turned into ground water, the groundwater table of the urban area will rise and the springs of Jinan City will be recovered.
In view of a dustpan basin structure, its activity characteristics and source supply style of deposits, the sequence stratigraphic styles of the steep slope, deep depression and gentle slope are described respectively.
The results indicate that the terrigenous sequences of the study area formed under the condition of high and uniform velocity of material source supply,and that S4 sequence of TST should be taken as important target for hydrocarbon exploration. \;
It becomes significant and necessary to study sedimentary facies, analyse sand facies distribution principles for exploration&development in this area. In terms of geological data provided by logging and signs to identify sedimentary facies, the study concludes different well logging displaying features for sub-sedimentary facies and micro-sedimentary facies by analysing interior bedding structural features of reservoir sand, variation of sedimentary energy, sedimentary rhythm and source supply inside sand facies.
, filling of epiric sea and filling of continental downwarping due to the reactivation of the aulacogen. The controlling factors of sedimentary facies evolution in this area have been analyzed in relation to structure, source supply, marine transgression, and paleoclimate.
It is demonstrated that the west of the depression was the main source supply area during s4 period, where had developed 4 major sources and formed fan delta sands like Shen257, Shen225, Shen267 and Shen278. s4 member mainly includes lowstand system tract and transgressive system tract.
A compact pulse generator for radiographic source supply
Thus promoting the source supply of photosynthates after anthesis is of major importance for grain to set and to develop.
An appropriately low plant density was suitable for prolonging the function of the middle and lower organs, delaying the senescence of plant, increasing the source supply for grain filling, and improving the grain yield.
When growing seaweeds in tanks, pH and carbon source supply have to be controlled in order to maximize photosynthesis.
Improvement of growth and camptothecin yield by altering nitrogen source supply in cell suspension cultures of Camptotheca acumi
