石蜡微胶囊中脲醛树脂壁材渗透性的研究

利用差示扫描量热法研究了石蜡微胶囊中脲醛树脂壁材对水及甲苯的渗透性 ,结果表明 ,水不能透过脲醛树脂壁材 ,而甲苯则易透过脲醛树脂壁材。因此 ,该石蜡微胶囊不能用于芳香族溶剂存在的场合。     

Mobile robot path planning based on hierarchical hexagonal decomposition and artificial potential fields

In this article, a new algorithm based on an artificial potential field and hierarchical cell decomposition technique is developed to solve the find-path problem for a mobile robot. The complete map of the workspace including obstacle locations is assumed to be known a priori. The basic cell structure used for decomposition is a hexagon. The artificial potential field is based on an attractive force from the goal position and repelling forces from the obstacles. Computer simulations of the algorithm for various obstacle scenarios are also presented. © 1994 John Wiley & Sons, Inc.

氧化铝/锌合金复合材料界面的SEM观察

利用挤压铸造制备氧化铝／锌合金复合材料，在扫描电镜（ＳＥＭ）上观察复合材料的界面。结果表明，在复合材料中纤维与基体间存在致密界面层，合金元素通过适当的化学反应可改善纤维与基体间的结合；在凝固过程中，纤维／基体界面上的硅在共晶体的共生生长过程中起了领先相作用，导致复合材料的共晶转变是由铝硅共晶转变和锌铝共晶转变两者组成。

Effects of lacidipine on serum oxygen free radicals and fasting levels of insulin in patients with essential hypertension

Thirty patients with mild to moderate essential hypertension had received four weeks treatment with Lacidipine and serum lipid peroxide (LPO), superoxide dismutase (SOD) and insulin levels were measured before and after treatment. The results showed: (1) there were decreased in SOD activity and increased Lpo content the patients group (P < 0.01); (2) after treated with Lacidipine, the SOD acitvity increased and Lpo content decreased (P < 0.01); (3) Lacidipine had obvious antihypertensive effect with no significant changes in heart rate; (4) Lacidipine had no significant effects on insulin, blood glucose and lipids. The results suggest that lacidipine is a safe and effective antihypertensive agent and can improve the metabolic balances in free radical system.
