phenylketonuria

Poly ( m - phenylene - isophthalamide ) ( mpia ) , poly ( p - phenylene and 4 , 4 ' - diphenyl ether terephthalamide ) ( dpeta ) etc nanoflbers are electrospun , and the different diameters of different polymers nanoflbers are described . the result is related with different molecular chains , and the structures of molecular chain decide the diameter ranges of electrospun fibers . the blend solutions of pan & second cellulose acetate ( sca ) are electrospun to get synthetic fabrics 進行聚間苯二甲酰間苯二胺( mpia ) 、聚4 , 4 ’ -二氨基二苯醚撐對苯二甲酰對苯二胺( dpeta )等高性能纖維的電紡絲,發現不同高聚物所能得纖維細度有較大差別,這與二者的分子鏈結構有很大的關系。

The third - order nonlinear optical properties of two kinds of - conjugated polymer , polyaniline and poly - phenylene vinylene , were studied . using n - methyl - pyrrolidone ( nmp ) as solvent , we prepared pan / nmp solution and methyl - replaced pan / nmp solution . using chloroform as solvent , we prepared 2 - methoxy - 5 - butoxy - ppv / chloroform solution and 2 - methoxy - 5 - decoxy - ppv / chloroform solution 以n -甲基吡咯烷酮( nmp )為溶劑,制得pan nmp溶液和甲基取代pan nmp溶液;以氯仿為溶劑,制得2 -甲氧基5 -丁氧基取代ppv氯仿溶液和2 -甲氧基5 -癸氧基取代ppv氯仿溶液。

The thermodynamic free energy on mixing and the spinodal equation in ternary homopolymer blends were obtained by making plausible approximation based on flory ' s equation of state theory . because of the non - linear behavior of the spinodal equation , a numerical solution approach was used and succeeded in solving the problem . spinodal of polystyrene ( ps ) / poly ( vinyl methyl ether ) ( pvme ) / poly ( 2 , 6 - dimethyl - 1 , 4 - phenylene oxide ) ( ppe ) were simulated over a wide temperature range and the calculated result was coincidence with that of the literature 將上述方法用于已知狀態方程參數的二元均聚共混體系聚苯乙烯( ps ) /聚甲基乙烯基醚( pvme ) ,三元均聚共混體系聚苯乙烯( ps ) /聚甲基乙烯基醚( pvme ) /聚2 , 6 -二甲基1 , 4 -苯撐氧( ppe ) ,得到一系列不同溫度下的spinodal相圖,預測結果與文獻報道吻合,在此基礎上進一步研究了聚合物的分子量對體系相行為的影響。

In the end of this chapter , we give the main result of the paper . in the second chapter , we calculate the values of wiener index for two classes of linear phenylene molecular graphs , and obtain the linear recursive formulas , and then we get the exact expressions by solving some difference equations of the recursions 在論文的第二章里,給出了兩類線性亞苯基圖的wiener數的遞推關系式,并通過求解差分方程獲得了兩類線性亞苯基圖的wiener數的顯式表達式,這一方法是以前沒有的。

This paper introduces the preparation and performance of a novel high performance pulp , poly ( p - benzamide ) ( pba ) pulp , which has bigger specific area and excellent heat - resistance than para - phenylene terephthalamide ( ppta ) pulp 摘要介紹了一種新型高性能漿粕聚對苯酰胺( pba )漿粕的制備和性能。該漿粕較聚對苯二甲酰對苯二胺( ppta )漿粕具有更大的比表面積,更優良的耐熱性。

Conductive polymer poly ( p - phenylene vinylene ) ( ppv ) and precursor of ppv were prepared via wessling ' s method . we have assembled cds nanoparticles with pdda , cupc and precursor of ppv into films by esam 采用靜電自組裝方法,將制各的cds納米顆粒分別與pdda 、 cupc 、 ppv前驅體組裝成膜,發現幾種體系均有良好的自組裝性能。
