It fills and expands the apical portion of the cell and forces the nucleus into the slender basal portion.

它充满并推向细胞的顶部，迫使核移向狭窄的基部。

Electrons of atom have orbits at different distances from the nucleus. For some atoms the electrons in the farthest orbits have only weak forces binding them to the atoms.

The repulsive forces exerted by the protons loosen the structure of the nucleus.

质子施加的斥力使原子核的结构松弛。

According to this theory, the atoms consist of a positively charged nucleus surrounded by a stream of electrons kept together by attractive forces from the nucleus.

根据这个理论，原子由一个带正电荷的核组成,由于来自核的吸引力,电子流围绕在核的周围。

And there are various forces that play in the nucleus that will dictate when this will be stable and when it won't be.They isolated it, but it decays very quickly on the order of microseconds Lifetime on the order of microseconds.

在原子核中有很多种力,都会产生作用，当条件是稳定的,还有当它不是的时候，它们提取出来，但是它会以微秒的速度衰变,生命只有几微秒长。

I am going to say if that electron is to stay in its orbit, that is to say it doesn't flee the atom, it doesn't collapse under the nucleus then the sum of the forces on the electron must be zero No net force. And so that will be the sum of a dynamic force plus an electrostatic.

如果电子会保持在它的轨道上运行,既不脱离原子的话，它就不会由于原子核对它的吸引力而被瓦解掉,电子所受的合力一定为零,由于没有合力,所以电子所受力为动态力和静电力的总和。

As a consequence of this additional uncertainty, if the quantum demon makes a measurement of a nucleus which forces it to choose one state or the other, he is creating new information.
