It is found that the alloy containing oxygen element is only composed of a single β phase, while the alloy without oxygen element consisted of β and α phases. Although the grain size becomes larger, the elastic de-formation ratio, strength, and hardness of the alloy are all increased with an increase of oxygen content. The as-cast alloy has excellent plastic deformation ability, but the cold-rolled alloy containing oxygen element exhibits brittle characteristics. A conclusion can be drawn that oxy-gen element can stabilize β phase, inhibit the phase transformation from β to α , and furthermore help to increase the strength and elastic de-formation ability of the alloy. 更多展开更多

Methods:30 cases of patients with Piyinxu were treated with Shen Rou Yang Zhen Decoction.The blood rheology was detected before and after treatment. Results:30 cases of patients with Piyinxu were treated for one course of treatment resulting in obvious efficiency in 9 cases(30 % ), efficiency in 19 cases(63.33 % ), inefficiency in 2 cases (6.67%). The overall effective rate was 93.33%. The indexes of blood rheology including blood viscosity and plasma viscosity were significantly reduced (P ＜ 0.01). Conclusions: Shen Rou Yang Zhen Decoction can reduce the blood viscosity and improve the blood rheology in patients with Piyinxu.展开更多
