When the aphids were feeding on Ww2730 seedlings, the time to 1st probing was delayed compared to those on Xiaoyan22 and Batis, searching was interrupted before 1st probing, and 1st probing was shorter than that on Xiaoyan22 and Batis significantly. Duration of pd Ⅱ-1 on Ww2730 and Xiaoyan22 was much longer than that on Batis. Duration of pd in C waveforms on Ww2730 was longer than that on Xiaoyan22 and Batis remarkedly. Times and duration of G waveform on Ww2730 were more and longer. Times of spot G waveform on Batis were more than on Ww2730 significantly, but the duration was shorter than those on Xiaoyan22 and Ww2730. Total time of E1 waveform, max longest duration of E1 fractions and mean duration time of E1 fractions following E2 wavefrom on Xiaoyan22 and Batis were all longer than on Ww2730 statistically. There were no differenences among mean durations of 1st E1 wavefrom on three varieties, but mean durations of other E1 waveforms on Ww2730 and Xiaoyan22 were shorter than those on Batis. The other waveform parameters, include times and durations of F and E2 were all not different on three wheat varieties.It is suggested that the resistance mechanism of wheat variety Ww2730 to S.

麦长管蚜在品种Ww2730上口针开始接触叶面时间显著晚于小偃22和Batis，第1次持续刺探前的刺探次数显著多于小偃22和Batis，开始刺入叶面后第1次刺探的持续时间极显著短于小偃22和Batis；在Ww2730和小偃22上的PdⅡ-1的平均时间显著长于Batis；Ww2730上C波阶段2个Pd波间的间隔平均时间显著大于另外2个品种；在Ww2730木质部取食的次数和时间显著大于其它2个品种；Batis上的点G波的次数极显著地高于Ww2730，而平均持续时间极显著短于小偃22和Ww2730；在Batis和小偃22上E1波的总时间，E1波的最大值、跟随E2波的E1波的平均时间均显著大于Ww2730；3个品种间第1次E1波持续的时间差异不显著，但Ww2730和小偃22上其它E1波持续的时间极显著少于Batis；3个品种上其它波形参数，包括F波的次数和总时间、E2波的次数和总时间没有差异。

In order to avoid eclipse type misidentification and to predict central durations, which are closer to the actual durations at total eclipses, this document departs from standard convention by adopting the smaller value of k=0.272281 for all umbral contacts.

为了避免日食类型的误认，预言中心持续时间（这个时间更接近全食实际持续时间），这份文件背离标准公约，对所有的本影内切采取更小的值K=
