RESEARCHES IN THERMAL DECOMPOSITION REACTION FOR STORAGE OF SOLAR ENERGY——PRIMARY STUDIES OF THE THERMAL DECOMPOSITION REACTION OF AMMONIUM HYDROGEN SULFATE
Stored at(54±1) ℃ for 7 d and 14 d,degraded rates of azadirachtin A in neem seed methanol extracts were 82.35% and 94.79%,and degraded rates of azadirachtin B in same condition were 20.32% and 54.75%.
Stored in methanol+water(55∶5,v/v)at(54±1) ℃ for 7 d and 14 d,degraded rates of azadirachtin A in neem seed methanol extracts were 33.59% and 54.45%,and degraded rates of azadirachtin B in same condition were 11.96% and 21.11%.
The five nutrient elements total storage in depth from 0 to 30 cm of the soil is 206 427.59 kg/hm~2, and available nutrient is 16 618.29 kg/hm~2, the crop nutrient elements storage amount just is occupying about 0.15% of the total nutrient store in the soil of five kind nutrient elements, and 1.95% of the available nutrient store in the soil of five kind nutrient elements.
Results indicated that the treatment of 10 μmol·L~(-1) ABA was the best with 2.9% bulbs germination rate after 100 days store,63.8% lower than the control.
Results The dose effect and time effect could be expressed by Y=95.4378D-91.2478 and Y=21.32T-3.96 respectively. The activity will decrease slightly with the rising of pH in pH conditions ranging from 5.5 to 8.5.Besides,the activity will not decrease after one year store or boiled at 100℃ for 2h.
The total store is 514.90 kg/hm~2 of the five kinds nutrient elements in the Robinia pseudoacacia forest ecosystem,and the tree layer nutrient element storage amount accouts for about 85.5 percent of total storage.
During the period 1800~1997, the North Pacific has taken up 23.75 GtC of anthropogenic CO_2 in RUN1. The subpolar region is an important export region of absorbed anthropogenic CO_2, where 38%~54% of the absorbed anthropogenic CO_2 is transported to other regions, whereas the region of 20°N~30°N is an important storing region, which amounts to 24% of the total storage in the North Pacific.
2) The water loss percentage and storing losses of team Ⅰwere respectively lower than teamⅡ, by 20.4%,26.4%; team Ⅲ by 23.15%,27.50% respectively(P<0.05),while,with the increasing of concentrated feed levels,the mutton become darker in color,quicker in fat aggradation and lower in cooker meat percentage.
Storing at 25℃, above 40%mixed oil(70% palm oil, 20%lard,10% tallow), and above 16% salt, the concentration of the maize starch is 1 5%~3 0%, Formulated sauce is good and satisfactory
Solar liquid desiccant air-conditioner is a new air-conditioning system in which liquid desiccant can be regenerated by solar energy and energy can be stored in the form of chemical energy in the liquid desiccant.
It needs three dual-port random-access memory (RAM) to store the temporary results and transpose the matrix, then builds up a pipeline model composed of the three 1-D DWTs.
We evaluated the possibility of storing the cultures of obligate anaerobic microorganisms (clostridia, acetogenic and sulfate-reducing bacteria, and methanogenic archaea) in 25% glycerol at -70°C for a long time (up to 3 years).
The designed procedures detect most of the defects in control circuits indirectly through data processing and storing devices without the use of control units.
This device, operating in the automatic mode as part of the hardware-software NMR system, makes possible recording, processing, and storing experimental results in electronic form.
