Again, this is a somewhat idealized assumption in that it assumes that the operator can determine that all remote phones are on-hook, that those phones truly represent high impedance in the ADSL band, and that if an ADSL modem is present at the remote, there is some means to force it into a high-impedance state.

再次，这是一个有些理想化的假设，假定操作员能确定所有的远程电话是挂机的，那些电话代表ADSL带宽中的阻抗，如果远端有一个ADSL调制解调器的话，有一些办法可以让它强制进入高阻抗状态。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
