Erysimi CarE activity both of resistant populations and of susceptive population were trend to normal school, and the resistant L. erysimi populations have significant higher CarE activity than susceptive L. erysimi population. Thereinto, the activity level of CartE in Hongtang L. erysimi population is the highest among the four field populations, which is tally to the result of drug-fast test on each population.

对各地菜缢管蚜种群个体羧酸酯酶研究结果表明，无论是抗性种群还是敏感种群，其个体羧酸酯酶活性分布频率均趋于正态分布，即两头低，中间高；各抗性种群的羧酸酯酶的活性水平明显高于敏感种群，其中以洪塘菜缢管蚜种群的羧酸酯酶活性水平最高，这跟各种群的抗药性监测结果亦相吻合。

B personal fable level of egocentrism had positive relationship with learning-adapted problems, but the relationship became negative as it is suppressed by self-control.

此意即青少年愈觉得自己是假想舞台中的焦点，则其发生青少年偏差行为、内向性偏差行为、学业适应问题的频率亦愈高。

The only difference would be that the electrically transmitted signal would be at a higher frequency.

唯一不同的是，采用电方式传输的信号使用的频率更高一些。

During the course of electro form process, we got ideal electro form process condition that can get windings with uniform granule and high compactness, including current waveform, frequency, duty ratio and voltage to the windings ect. Affect of underlay's flatness to the electroform process are also analysed in detail. Compatibility between photoresist and electroforming solution is also solved.
