1.The results indicated that Liangyoupeijiu showed better plant and leaf type, higher ratio of grains to leaf area and larger photosynthesis area, stronger ability of population dry matter accumulation during the period of vegetative growth especially from heading to being mature, longer leaf duration and grains-filling after heading than that of its parents and controls s; more grains per panicle, lager all sink per plant and 1000-grain weight.
2.The middle sized seeds (0.1 - 10mg) were either abundant and broadly distributed in vegetation, total soil seed banks, seedling banks and persistent seed banks.
3.The ratio of ATP to total adenylate pool in acute and chronic hypoxia groups was respectively 41 5% and 42 5% of that in the normoxic control group.
4.Xiao Yun: Miyun reservoir covers an area of 224 square meters. And its magnificence in terms of area and capacity is famous in the entire North China.
5.With proper extent of the restriction enzyme digestion of yeast DNA,F/V ratio for ligation at 15/1,DNA concentration for ligation at 200-250 ng/ml and BHB2688/BHB2690 for in vitro packaging at 5/1,we got rather high efficiency of library construction (106 CFU/μg vector DNA) and low Apr Tcr % (down to less than 10% or even 5%).
6.Results and conclusion The structure of vecuronium bromide was elucidated by IR,DSC,~1H-NMR,()~(13)C-NMR and MS,the overall yield is 13.7%.
7.The major research questions are the following:(1) The coverage rate of CET-4 words in MEE texts and in the four sub-corpora of MEE corpus.
8.The phosphorous content of bryophyte was higher than that of arbor,and 2.4 and 792 times as much as that of herb and shrub,respectively,indicating that bryophyte was an important phosphorous pool.
9.The three pools comply with three first order model. The paper uses the model and decomposition curves of soil organic carbon to fit active pool and its decomposition rate,slow pool and its decomposition rate. The results show that the size of active pool from different profiles accounts for 0.5%~7.6% of total soil organic carbon and the mean residue time is 41~64 days;
10.By developed data interface between database and model base,the system can realize data interaction. Employing programming technology mixedwith different language, the system can realize connection between the chief programdeveloped with Delphi and model programs with Matlab and Lingo, elaboratesuperiority of different language, enable system structure more rational, run faster.
