地球以外的

Over break 3. But even assuming that a planet is the right size and has the proper chemical composition and a stable orbit neither too far from its star nor too close, so that its temperature is at all times in the range of liquid water (as is true of Earth except for the polar regions), a great deal would stilldepend on the kind of star it was revolving about.

over break 但是即使假定有一颗行星，它的大小正好，化学成分适宜，运行轨道稳定，与恒星的距离既不太远也不太近，气温始终保持在液态水温的范围内（正如地球上极地以外地区的温度一样），那儿是否存在生命，在很大程度上仍得取决于它所围绕运转的是什么样的恒星。

Take sensible precautions, but for large boulders that survive and thud to Earth, there is little that can be done.

除了巨大的圆石能够残留下来并且重击到地球上以外，几乎没有什么可以去做的。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

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。
