Water balance indicates that available water resources of 437 640 000 m~3/a could be increased through enhancing artificial regulation,which will be significant to resolve the water supply problem in the near future and increases the water supply ability during an emergency in Dalian area.
In order to make aim fragments expressed timely, measurably and effectively in transgenic plants, gene expression system was established by an effective gene switch erected in the upper of expressed aim gene to realize artificial controls for gene expression.
With the control of ecological factors, fish can be induced to spawn synchronously with average rates of fertilization and incubation reaching 80 9% and 76 3% respectively.
Tet system, from multitudinous regulative system blooming, is widely applied to each biology domain because of tightly regulated control of gene-expression.
According to the mul ticomponent system phase diagram of Na_2SO_4-NaCl-H_2O,broad daylight dehydration transformation from mirabilite to anhydrous sodium sulphate in the brine,by man-made controlling the components of the brine in the solar pool in summer time and adding to the kool properly ancrystallizing additine was studied.
Investigations have been carried out on the single and interrelated effects of high (30/25℃) and low (natural winter temperature, avg. temp. = 17. 8℃) air temperatures, as well as high (80%-90%F. C. ) and low ( 40% - 50%F. C) soil moistures.
A reasonable use of a karst water resource and its better management cannot be considered without artificial control of the groundwater regime, i.e., without adjusting the regime to human demands.
We show that the study of natural exotic sensory systems can lead to discoveries that are useful for the construction of technical sensors and artificial control systems.
