Compared with SHRc , after 4 weeks, Pro-EGF mRNA expression level of SHRsv and SHRlv VSMC were significant lower.Conclusions: Valsartan decrease SBP of SHR, inhibit SHR VSMC proliferation, reverse vascular hypertrophy of thoracic aorta and mesenteric artery in SHR, improve the two arteries vasomotion function. Pro-EGF mRNA expression only in SHR VSMC, not in the VSMC of WKY. It indicated pro-EGF gene may play an important role in hypertension advance .

为此，本文做了以下工作：首先，为了形成对粘弹性聚合物溶液在微观孔隙中流动行为的完整的数学描述，便于从理论上研究粘弹性流体的微观驱油效率，本文针对残余油的多种微观存在形式，使用了两种孔隙模型：扩张通道模型、带横向槽的流道模型。

The steam acts upon the surface of the water in the receiver, which surface only being heated by the steam, it does not condense, but the steam gravitates or presses with an elastic quality like air, and still increasing its elasticity or spring, until it counterpoises, or rather exceeds, the weight of the column of water in the force pipe, which then it will necessarily drive up that pipe; the steam then takes some time to recover its power, but it will at last discharge the water out at the top of the pipe You may see on the outside of the receiver how the water goes out, as well as if it were transparent; for, so far as the steam is contained within the vessel, it is dry without, and so hot as scarcely to endure the least touch of the hand; but so far as the water is inside the vessel, it will be cold and wet on the outside, where any water has fallen on it; which cold and moisture vanish as fast as the steam takes the place of the water in its descent.

&&蒸汽行为后，水面在接收端，而只是表面被加热水蒸汽，它不浓密，但相互依赖蒸汽或印刷机具有弹性质量一样的空气，并仍在增加其弹性，或春天，直到它网，而超过重量栏水警队管道，然后它一定会推到管；蒸汽则需要一段时间来恢复其权力，但它会在最后排放水出顶管，你可以看到外面的接收机如何当然水，以及如果它的透明度；，目前为止由于蒸汽载船，它是未经干燥，所以作为热几乎要忍受至少触摸的手；但到目前为止，由于水内的船只，将寒冷和潮湿对外面，那里没有水落下；其中寒冷和水分消失快蒸汽需地方水在其后裔。
