新媒体的崛起给传统电视台带来了巨大压力,凤凰卫视必须在保持自身特色的同时,寻求转型和创新。站在凤凰卫视的大楼前,刘长乐望着这座他倾注了大半生心血的媒体帝国,眼神中既有不舍,又有对未来的期许。摆正心态,认真思考和了解上班的真正意义,或许,工作反倒会成为你成功的垫脚石,保养身心的最佳渠道。

Put a tentative charge into the electric field and determine the electric field force to which the charge is subjected, and the ratio of the electric field force to the charge charge.

In general, the positive and negative bound charges inside the dielectric without the action of the electric field are offset on average, and the macroscopic level does not show electrical properties.jihua:zaiwaidianchangdezuoyongxia,shufudianhedejubuyidongdaozhihongguanshangxianshichudianxing,zaidianjiezhidebiaomianheneibubujunyundedifangchuxiandianhe,chuxiandedianhechengweijihuadianhe。chongmandianjiezhidedianrongqibizhenkongdianrongqidedianrongdajiushiyouyudianjiezhidejihuazuoyong。Polarization: Under the action of the external electric field, the local movement of the bound charge causes the macroscopic display of electricity, and the charge appears on the surface and internal unevenness of the dielectric, and the charge that appears is called the polarized charge. The larger capacitance of a dielectric-filled capacitor than a vacuum capacitor is due to the polarization of the dielectric.dianweiyishiliang:shiyigeyongyimiaoshudianchangdefuzhuwuliliang,yongfuhaoDbiaoshi。Electric displacement vector: is an auxiliary physical quantity used to describe the electric field, denoted by the symbol D.dingyishiwei:D=ε0E+PThe definition is: D=ε0E+Pdianrongqidedianrong:C=Q/UThe capacitance of the capacitor: C=Q/Udianchangdenengliang:shidianchangsuojuyoudenengliang,dengyudianchangnengliangmiduduidianchangsuochukongjiandejifen。The energy of the electric field: it is the energy of the electric field, which is equal to the integral of the energy density of the electric field to the space at the electric field.jintiandefenxiangjiudaozheliliao。ruguoninduijintiandewenzhangyoushimedutedexiangfa,huanyingpinglunliuyan,rangwomenxiangyuemingtian,zhuninjintianguodekaixinkuaile!That's it for today's sharing.If you have any unique ideas for today's article, please leave a comment, let us meet tomorrow,I wish you a happy day!
