光强、光质、温度、土壤水分和蒸腾速率等因子的变化都会导致植物叶片膨压的变化,已有的测定方法如压力室、谐振频率和热电偶湿度计法都不适于连续快速测定叶片的膨压。较先进的压力探针(pres-sure probe)技术在测定叶片细胞的膨压时也... 光强、光质、温度、土壤水分和蒸腾速率等因子的变化都会导致植物叶片膨压的变化,已有的测定方法如压力室、谐振频率和热电偶湿度计法都不适于连续快速测定叶片的膨压。较先进的压力探针(pres-sure probe)技术在测定叶片细胞的膨压时也存在着剥皮时改变组织水势的困难。我们在天平法的基础上改进建立了挂码法。 展开更多

The purpose of this study was to investigate the memory effects of the postgraduates’memorizing Everyday English from 30 to 100 using the Natural Numeral Imagery Memory(Method by memorizing the concrete objects associated with the shapes of Arabic numeral to produce marvelous imagination,MMOASAPMI).The results indicated as follows:Firstly,the postgraduates,who applied the MMOASAPMI to memorize and recall the Everyday English from 30 to 100,could recite them well in sequence backward,forward,and randomly.The reaction time of reciting any sentence randomly is no more than 2 seconds.Secondly,it can transform the materials of the short-term memory into long-term memory quickly,and effectively prevent them from the interference of proactive and retroactive inhibition,so it is useful for keeping memorized information with less loss and remaining for a long period.Thirdly,with the materials in strong sequence,large quantities and the difficulty to memorize,it is an extremely effective method for memorizing them.Fourthly,the keys to improving the memory efficiency are the well-storing skills of memory,storing methods,and memory clues. 展开更多
