This industry also has SEO of make one's bow more than one year, although be not a patch on those elder people, but my train of thought is very clear: Learn to do a station to learn SEO at the same time at the same time---Share with the person-- let more people know me-- the ability that receives a few little sheet to raise his-- share a few experience that make sheet and person-- let more people know me-- receive larger sheet-- oneself promote when making larger sheet-- this a series of the thing that gets in the process serves for his career-- continue to share...

正式进入SEO这个行业也有一年多了，虽然比不上那些前辈们，但我的思路是很清楚的：一边学做站一边学习SEO---与人分享--让更多的人熟悉我--接一些小单提高自己的能力--将做单的一些经验与人分享--让更多的人熟悉我--接更大的单--在做更大的单的时候提升自己--将这一系列的过程中所得到的东西为自己的事业服务--继续分享。。。

The results showed that after the adding starch to the sheet, the viscosity of the PVA solution increased, the dissolution time of the sheet got longer, the rate of enlargement in water was smaller, the rate of moisture became smaller, stretch intensity enhanced and the change of shape diminished; also it could be seen from the surface of sheet that the starch existed in PVA sheet as the shape of conglomerating particle.
