deam

The effect of DEAM contents and pH on the conformation of P ( DEAM co MAA) may find some uses in the design and synthesis of novel sensitive gels.

P（DEAM-co-MAA）构象随其组成和pH变化的这种性质有可能在新型敏感性凝胶的合成设计上获得应用。

But the conformation of P ( DEAM co MAA) in dilute aqueous solution shows a loose extended form due to polymer dilution effect in all of pH range when the molar fraction of DEAM in P ( DEAM co MAA) is higher than 8.00%.

当共聚物中DEAM含量大于8.00%（molarfraction）时，由于高分子的稀释效应，P（DEAM-co-MAA）在pH2～10范围内表现为较为松散的伸展构象。

When the DEAM contents were lower, the graft copolymer conformation behavior was like homopolymer PMAA.

PDEAM接枝率较低时，P（MAA-g-DEAM）的构象行为类似于PMAA均聚物。

How ofen do we plant the seed of a beautiful deam in the fertile soil of our minds, and then dig it up?

我们在心灵的沃土中，播下一颗美好梦想的种子后。是不是不待它生根发芽就将它掘出土壤？这样的事情每隔多长时间我们就会做一次呢？
