仔鱼初次摄食饥饿“不可逆点”(thepointofnoreturn ,PNR) ,即初次摄食期仔鱼耐受饥饿的时间临界点 。
...认为是初次摄食期仔鱼死亡的主要原因之一,自从20世纪60年代初由Blaxt二和Hempel首次提出“不可逆点”(the point of no return,PNR)的概念后,有关仔鱼“不可逆点”的概念就被学者们纷纷应用于各种鱼的研究‘,,。

Feeding intensity and point-of-no-return (PNR) of Pelteobogrus fulvidraco larvae at different temperatures were studied under laboratory conditions.
她与同事致力于研究对于北冰洋上的海冰是否存在一个不可逆转的“消融点”,一旦达到该点即使气候转凉海冰也无法恢复原来的覆盖量。
She and other scientists are researching whether there might be a 'tipping point' for Arctic sea ice -a point at which sea ice will disappear and never recover, even if the climate cools.
但他又表示,其他科学家说,再有十年,我们就会到达不可逆转点。
But he said other scientists say there is only a decade left before we reach the irreversible point.
If it was non-reversible, I would be allowed to put an initial point and a final point, but I wouldn't be allowed to put a path between them like this, connecting them together.
如果是不可逆过程,我可以画出过程的初态点,和末态点,但是我不能再像这样,画出连接这两个点的,路径曲线来。
