在这些实验中,试验者的大脑中既没有显示杏仁核的活动,也没有显示前扣带皮层的活动,这表明之前的实验结果确实是由社会压力引起的,而不是由心理活动引起的。
These experiments showed no activity in either the amygdalas or the pACC, suggesting that the earlier results were indeed the result of social stress rather than mental exertion.
中心有个带正电的原子核。
虽然扣带皮层部位的活动受人在早年成长时期就已经编好的程序控制,但似乎杏仁核才是此时此刻的及时回应,扣带皮层部位并没有像杏仁核那样做出相同,柔性的反应。
The amygdalas thus seem to respond to the here-and-now whereas the pACC is programmed early on, and does not react in the same, flexible way as the amygdalas.
扣带皮层部位是大脑皮层的一部分(也在【两个】大脑半球),它对杏仁核进行调节。
The pACC is part of the cerebral cortex (again, found in both hemispheres) that regulates the amygdalas.

这也是很合理的,因为Z就是原子序数,假设原子序数是,那就有3个电子,那我们就希望,性原子有个带3个正电荷的原子核。
So, let's say we have an atomic number of 3, 3 that means we have 3 electrons, so we better hope to get our neutral atom that we have a charge of plus 3in the nucleus.

Alpha particles are positively charged helium nuclei obtained from natural radioactive decay.
质子虽然很重,但要受原子核的排斥,因为它们都带正电荷。
The proton, although it was heavy, would be repelled by nucleus, since they both have positive charges.
例如,心肌细胞有两个核,这样,DNA计数加倍,以致碳14的核定值被带高。
For example, heart muscle cells have two nuclei, which means the DNA could be in there twice, so this could screw up the carbon 14 dating.

The nucleus consists of uncharged neutrons and positively charged protons. negatively charged electrons travel around the nucleus in their orbits, similar to the way planets moving around the sun.
包含了一个单独的电子轨道,一个带正电荷的核。
And, it involves a single electron orbiting a positively charged nucleus.
所以即使把一个原子的所有电子都拿走,原子核还是带那么多的正电。
So even if we strip an atom of all of its electrons, we still have that same amount of positive charge in the nucleus.
