目的用聚乳酸(P l.)构建一种含有甲状腺激素(T3),并具有纵行排列管经三维立体结构的神经组织工程支架,观察支架中T3溶出度的变化及其对大鼠血清T3的影响。方法按每毫克消旋聚乳酸(PDl.A)中含35ngT3的比例将T3混合在PDl.A中,采用热致相分离法制备三维立体支架,支架内表面涂附纤维粘连蛋白,做扫描电镜观察。同时用放射免疫测定法测定T3溶出度。将材料埋入大鼠体内,分别在1-7天,2、4、8周10个时象点检测大鼠血清T3的浓度,并比较该材料对大鼠血清T3的影响。结果构建的支架材料具有管状纵行排列的立体结构,孔径60-100μm之间。材料每天释放0.96-1.80ngT3,植入体内后大鼠体内的T3浓度均在0.87-1.03ng/m l.围。结论用热致相分离法制备的P l.三维立体支架有良好的立体构型,类似周围神经结构。材料的T3能平稳地释放,植入体内后大鼠体内的血清T3浓度均在正常范围内,对大鼠血清T3浓度无影响。

The resul.s of the impl.mentation of an actual.microgrid in the Netherl.nds are presented. This microgrid has photov.l.aic panel. as microsources, energy storage, and a fl.xibl. AC distribution interfacing system that can operate connected to the publ.c grid or autonomousl. where it regul.tes the site＇s v.l.age and frequency. In this paper, the potential.of the microgrid in improv.ng power qual.ty issues of the site, specifical.y harmonic distortions, is demonstrated. Resul.s show that fl.xibl. AC distribution interfacing system dev.ces were abl. to compensate v.l.age harmonics when the microgrid was operating connected to the publ.c grid and when operating autonomousl.. Other tests such as short-circuit, synchronization and bl.ckstart were al.o conducted. The improv.ment in power qual.ty and positiv. resul.s of the other tests demonstrate that a sel.-supporting, rel.abl. and efficient operation of the microgrid can be achiev.d.

铅酸胶体电解液蓄电池推荐的充电电压范围为2.32～2.35v.单体。胶体电池充电到此电压值时可保持其容量达到许多次循环。相反,相似的液体电解液的铅蓄电池需要的电压范围为2.5～2.67v.能保持容量。允许胶体电池以如此较低的电压进行充电的主要因素是,负极板由于氧再化合反应而去极化。胶体酸也可促使硫酸铅转换成二氧化铅。胶体电解液蓄电池所需的较低电压将导致水耗减少,工作温度降低。
