xlabel('Time(BT)','fontsize',18,'FontWeight','bold','fontname','宋体');
ylabel('Diameter(μm)','fontsize',18,'FontWeight','bold','fontname','宋体');
set(gca,'Linewidth',1.5,'fontsize',14);
set(gca,'xtick',[1,121,241,361,481,601,721,841,961,1081,1201,1321,1441,1561,1681,1861],'LineWidth',1.5);
set(gca,'xticklabel',{'12.25 14:00','16:00','18:00','20:00','22:00','00:00','02:00','04:00','06:00','08:00','10:00','12:00','14:00','16:00','18:00','21:00'},'fontname','宋体','fontsize',14);
set(gca,'YTick',1:1:20,'LineWidth',1.5);
set(gca,'YTickLabel',{'2','4','6','8','10','12','14','16','18','20','23','26',...
    '29','32','35','38','41','44','47'...
    '50'},'fontsize',14,'fontname','宋体')
