变酸

The Gel Permeation Chromatography results indicated that the molecular distribution of end capped PAA was smaller than that of the no end-capped one. The Differential Scanning Calorimetry results showed PA end- capped polyimide films exhibited slower rising range of the T compared to no end cappers films'.

结果表明，封端可有效阻止分子链的无序增长，使聚酰胺酸分子量分布变窄；且可明显减少分子链在高温下的反应，表现为热处理前后封端薄膜T变化明显小于未封端的薄膜。

ABSTRACT Lithium niobate, an excellent man-grown crystal, has many classical properties for both research and applications, such as electro-optic, acousto-optic, Thermal-optic, Piezoelectric and Photorefractive effects.

铌酸锂晶体是一种优良的人工晶体，它具有很多重要的性质如经典的电光效应、声光效应、热电效应、压电效应、弹光效应、光折变效应等等，而且在这些方面几乎都有很重要的应用。

When he reached the foot of the stairs the count once more felt the hot breath upon his neck and shoulders. As of old it was laden with the odor of women, wafted amid floods of light and sound from the dressing rooms above, and now with every upward step he took the musky scent of powders and the tart perfume of toilet vinegars heated and bewildered him more and more.

伯爵走到楼梯脚下时，感到有一股炽热的气流吹到他的后颈上，热气中夹有一股女人身上发出的香味，这股香味是随着光线和声音一起从化妆室里落下来的；他每上一个梯级，那香粉的麝香味，梳洗水的酸醋味使他身上变得热乎乎的，他感到头晕目眩。
