The Centre will continue in the pioneering traditions of astrobiology on panspermia, interstellar and cometary dust, meteorites from Mars, the connection between comets and terrestrial life, and comet-Earth interactions so on.

中心将继续在太空生物学方面的研究，包括胚种学，星际和彗星尘埃，火星陨石，彗星和陆地生物间的联系，彗星与地球间的关系等。

Also, as our sun orbits the galactic center it may sweep through areas of interstellar dustiness.

也可能是，太阳运行在银河系中扫过的星际中的尘埃。

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。
