The spacecraft\'s autonomous navigation technology in the future is a best way by means of x-ray pulsar navigation;it can be used in the determi-nation of the Near-space,the solar system and the Milky Way,such as the position,speed,attitude and time of orbiting space-crafts,so as to ...
This allows the bacteria to reproduce immediately in yeast cells, making the way these proteins are made more efficient. It is easy to perform all kinds of genetic engineering manipulations with NAs, for example, to create more efficient synthesis structures, including two or more NAs and other ...
