Pick Ecological system is one of the main area ecology structural and functional unit， belong to the highest level of Life on earth is carbon chain of life， the yankees -- and artificial life is the true life forms to the lab， the development and research of ecological system simulation is actually tried to establish an artificial environment， in this environment， use the computer to ecological system， and simulation through the animal species caught between capture and the relationship between the dynamic balance system， establish， people can better understand the people around the Based on artificial life is the basic idea of the computer simulation method， and the description of the This system based on research on ecological chain， JAVA language design of real life imitating some basic characteristics， so as to realize artificial When in the process of the basic elements of artificial life after setting， procedure and cannot foresee generated in the development of artificial life， even in different conditions can produce different 希望对你有帮助
Abstract: The market demand for larger Aesculus， Aesculus However， due to the way conventional breeding sow reproduction， slow reproduction， combined with the strong low Aesculus seed and easy to inactivation， the rate of seedlings less unearthed Therefore， a lower reproductive rate and are difficult to meet the market Therefore， the length of flowering period， the impact of climatic conditions， as well as the form of flower structure， flowering to the length of pollen viability， pollen viability of different conditions， the effects of seed vigor， such as the determination of some physiological indicators of Aesculus proven to lower seed-setting rate， the reasons for the low rate of reproduction， in order to improve the seed-setting rate Aesculus， reproduction rate to identify the theoretical basis， in order to improve the breeding Aesculus to take concrete measures to meet the needs of the 还有这个标题：Aesculus Growth Characteristics of Flowering and Fruiting
Duck LiMo epidemic Riemerella anatipestifer coli (RA) in China， the serum type complex influenza epidemic duck LiMo coli serum type reports in the majority with type In type 1 strain， high serum free for clinical diagnosis and classification has important The experiment will strain type 1 duck LiMo epidemic strain on expanding coli bacteria and concentrated training after's adjuvants and incomplete adjuvants emulsion's preparation's adjuvants inactivated vaccine and oil emulsion's not completely adjuvants inactivated vaccine， used oil emulsion immune Immune program is as follows: using the free two injection's fins completely adjuvants inactivated vaccine 1ml/oil emulsion， first from the only after 10d 20d and to 0 ml/only six injection RA's not completely adjuvants inactivated vaccine oil emulsion were free， three Three from 10 days after the blood test for 1 to 0， SiMian continue in 31 days， 33 days， 35 days of rabbit ears and along the intravenous RA microbial 1 ml/ml/only only， 3， 5 ml/ After SiMian 9 days to try for the high price of blood， serum by heart bleed The laboratory test and proof of clinical application， duck LiMo epidemic coli type 1 high serum free with antibody titer high and high
Goal: Understood the thyroxine acceptor β△ gene in big mouse different organization distributed characteristic， is familiar with with PT-PCR analyzes the Method: TRβ△ the gene has the expression in many kinds of organizations， in which liver， the brain， the skeleton muscle， the heart， the kidney expression are Withdraws big mouse many place organizations mRNA， withdraws mRNA is the template counter duplication synthesizes the cDNA first And expands take it as template PCR increases the goal gene which TRβ△ the double strand cDNA basis copies to design two to direct the Uses fluorescence quota PCR the method to carry on the quantitative Finally: The extraction organizes total RNA， OD260/OD280 to be situated between between 7-0， OD260/230 is situated between between 5- The agarose gel electrophoresis appraises PCR to expand increases the result to demonstrate that， has the goal about anticipated 160bp to expand approximately increases the product belt TRβΔ PCR product the agarose gel electrophoresis appraisal result to indicate， expands the DNA molecular weight size after PCR which increases is the 176bp goal The goal gene and the steward gene quantitative determination， it expands increases the curve and the curve of solubility has not seen the mixed peak， simultaneously melts the tune prominent peak correspondence Tm value with to expand increases the product theory Tm to be Conclusion: The findings showed TRβ△ the gene has certain spatial distribution characteristic in the mRNA level expression: The liver， the brain， the spleen， in the kidney organization has this gene expression， also in the spleen expression quantity is higher than other organizations
Corn rhizosphere， the separation of Health and the nature of a preliminary study Abstract: This paper discussed by the natural conditions of the corn plant roots separation， purification be the root of the plate， their classification identification of patterns; will be pure The re-vaccinated within the plate in the tissue culture vaccine without access to the corn roots， determine the host of the corn plant growth and development; isolated to the growth of corn in the role of Health has Yijun; Key words: corn ; Within the Health and bacteria; separation; symbiotic colonization
