[ Method] Taking tender leaves of wheat as test materials, total DNA of transgenic wheat was extracted by using modified CTAB method. The extracted DNA was detected by 0.8% agarose gel electrophoresis. [ Result] DNA purity of extracted genome DNA from wheat was high and no degradation phenomenon using modified CTAB method, and was suitable for carrying out normal PCR amplification. [ Conclusion] This study provides a simple and quick method for extracting DNA from wheat with a spot of material.展开更多

Based on the analyzed results of charging characteristic of lead acid battery, a pulse quick charger is designed to adjust the charging current pulse’s amplitude and pulse width automatically stage by stage according to the measured battery voltage and feedback current. Compared with other kinds of quick chargers, it has such characteristics as shorter charging time, higher charging efficiency and lower temperature increasing during the charging process. As a result, the battery polarization is reduced efficiently.展开更多
