1.我們使用軟件,選取晶粒分布較為均勻的微晶玻璃TEM圖中多次隨機測量,測量并畫出一個晶粒的中心點到周圍最近鄰的幾個晶粒的中心點的直線,然后測量從單個晶粒表面到其他晶粒表面的距離,最后繪制統(tǒng)計圖。 2.Zn只有67Zn 有自旋,67Zn的自然豐度只有4%,而且67Zn四偶極作用很強,共振頻率又低,所以得不到信號。(自然豐度:natural abundance) |

1. 我們使用軟件,選取晶粒分布較為均勻的微晶玻璃TEM圖中多次隨機測量,測量并畫出一個晶粒的中心點到周圍最近鄰的幾個晶粒的中心點的直線,然后測量從單個晶粒表面到其他晶粒表面的距離,最后繪制統(tǒng)計圖。 We picked some TEM photos in which crystal particles were relatively evenly distributed, did random analysises by using software, to first identify the center of a crystal, then did same for the neighboring particles. We then measure the distance from the center of one crystal to the same of the others, and then repeated the same measurement, only to change it from center-to-center to from the surface of a crystal to the same of the others, and plotted the data into a histogram. 2.Zn只有67Zn 有自旋,67Zn的自然豐度只有4%,而且67Zn四偶極作用很強,共振頻率又低,所以得不到信號。(自然豐度:natural abundance) Among all isotopes of the element Zinc, only 67Zn possesses self-spin property. Due to the facts that it is low in the natural abundance (only 4%), and it has a very strong quadruple effect, together with a low frequency in resonance, we were unable to obtain any measurable signals. |
