Safety improvement of nuclear servicing ships to reduce possible radiation effects after sinkage .
核勤务船下沉后减小可能的辐射作用的安全改进。
The cause of sinkage is in a sense the season itself : in the heart of the summer , fat , ripe berries may be more dense than batter , causing them to drop .
However , because of the manifolded effects of many factors , such as sinkage , multipass , slip , slip-sikage etc. , it is very complex to simulate the wheel-soil interaction .
