Researchers used cell-phone-like tracking devices, for example, to record the Arctic migration of narwhals, a whale with a long twisted tooth, and remotely operated submersible s to reach several kilometers down into the oceans to study delicate marine animals that are impossible to collect.

研究员们用一种类似于微型电话的探测器来追逐，比方说，可用来追踪有一个弯曲的大牙齿北极独角鲸的迁移。遥控潜水器到达数千米深的海底去研究那些微妙的不容易追踪的生物。

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。
