The utility model relates to a chemical element electron configuration demonstration board used for chemical teaching experiments in secondary schools. The utility model technically design the electron number contained by each electron sheath for atoms of 18 elements from Hydrogen to Argon in chemistry ...
接下来一切操作都在dist文件夹目录下。 第四步:安装Electron 执行命令: cnpm install -g electron 1. 安装成功后执行:electron -v 查看一下是否安装成功 第五步:创建主程序的入口(main.js),及相关配置 package.json 在dist文件夹内创建main.js文件及package.json 文件 文件内容如下: main.js const {app, Bro...

We used the projector augmented-wave method63,64 to describe the electron–ion interactions and the generalized gradient approximation for exchange-correlation functionals. The valence electrons of Ni, Co, and Cr were specified as 3d84s2, 3d74s2, and 3d54s2, respectively. The spin-polarization ...
The single element antenna is replicated along the Y-axis (case 1, Figure 4a) and X-axis (case 2, Figure 4b) to achieve the MIMO configuration. Case 1 has a separate ground profile with elements having similar orientation, whereas in case 2, the antennas are arranged oppositely with a co...
The winding configuration used is the asymmetrical six-phase winding, where the spatial angle between the two three-phase winding sets is 30∘30°. The transition between propulsion mode and charging mode is achieved through a simple hardware reconfiguration. Figure 1. Six-phase integrated OBC’s...
Metallographic analysis was carried out on an Olympus PMG3 optical microscope (OM). The samples were etched in a solution containing 20 mL nitric acid (60% concentration), 20 mL hydrochloric acid (36% concentration) and 60 mL water. For transmission electron microscopic (TEM) analyses, discs ...
