山东航空公司空勤人员预防非典的措施

Results : There was no significant difference in the retinal blood flow between the stage 1 of SRAS patients group and the control group ( P > 0.05 ) .

两组间的血流频谱参数，经χ2检验，有显著差异（P<0.01）。

Objective : To observe the hemodynamics of central retinal artery ( CRA ) in the patients with senile retinal arteriosclerosis ( SRAS ) .

目的：观测老年视网膜动脉硬化各期的视网膜中央动脉血流动力学变化，探讨视网膜中央动脉血流频谱参数特征及其临床应用价值。

Moreover , after optimizing and emulsification ( Tween emulsifier ) modifying the system of SRA , optimum ratio of SRA – 1 and SRA – 2 in mass is 7:3 . The shrinkage reducing ratio of modified SRAs is improved by 10 % & 30 % .

SRA–1与SRA–2的最优质量比为7：3且乳化剂为吐温系列时改性效果较好。改性后减缩剂的自收缩减缩率提高了10%～30%。
