The proportions of Si-O-Si bridge bonds enhanced while the duty cycle increasing. 占空比升高时氧化硅桥键所占比例持续增加。
Background: AIDS epidemics and infection is on the rise in China, the bridge population bonds the normal population to the high-risks, block the transmission in bridge population is becoming the priority in AIDS epidemic control and prevention. 背景:我国艾滋病感染状况和流行形势日趋严重,桥梁人群正在使HIV从高危人群向一般人群播散,阻断桥梁人群传播艾滋病的方法和措施研究已成为控制HIV流行的优先领域。
We use N-ethyl carbazole as the electron donating group, and the cyanoacetate as the electron-withdrawing group, connecting the two parts together by converting different II bridge bonds. 以n-乙基咔唑作为供电子基团,氰基乙酸为拉电子基团,通过变换不同的∏桥键来合成。
