哎，只是我设置的字体比他的小，我想设置小于10的字体。

咦，突然想到了，chrome 在字体小于12px后会默认字体为12px这个梗，于是找找关于css字体方面的设置[https://www.cnblogs.com/jiangxiaobo/p/5669976.html][https_www.cnblogs.com_jiangxiaobo_p_5669976.html]

OK，问题解决

openlayers 的Text 对象就有这个属性，只是自己不会用罢了（大佬勿笑）怪自己菜。

加个 `scale:0.64,` OK

text: new Text({ 
         scale:0.64, 
      	 font: 'bold 0.11rem 微软雅黑 ',
         text: hasLabel ? data[i].value+'\n'+data[i].name  : '',
         fill: new Fill({ 
           color:'#000'
         }),
         stroke: new Stroke({ 
           color: '#fff',
           width: 3
         })
       })
