Secondly, the interphase layer is homogenized as a micropolar material model, and the analytical expressions for the local stress and couple stress and their corresponding average are derived for a coated fiber embedded in an infinite matrix under remote classical loading. This exact relation is compared with that determined through an approximate average equivalent inclusion method , and results show that the AEIM has good accuracy to be applied to evaluate the effective property.

就有效性质而言，对于所考察的硬界面复合材料来说均匀界面层的估计要高于非均匀界面层，但两者相差不大；对局部应力分布的预测，均匀界面层与非均匀界面层有较大差别，这说明对于与局部应力密切相关的损伤现象的预测，考虑非均匀界面层是十分必要的。

并将辐射损失速率与非热电子束轰击和软x线作用下的产能率作了比较，结果表明：耀斑不同时刻的色球辐射损失变化可达一个量级以上；耀斑脉冲相前后电子束加热相当有效；耀斑强度极大时，电子束轰击和软x线加热都有作用；耀斑主相时，软x线加热更能有效地平衡辐射损失。

CaN Aβ gene silencing can reduce myocardial hypertrophy in cultured cells, si1280 (21bp) of CaN Aβ gene is the most effective target site for siRNA. The method of intrapericardial injection of plasmid, microbubbles and erzymes can improve transfection efficiency of non-viral plasmid with satisfying targeted transfection. But the scope of transfected myocytes is still limited. CaN Aβ shRNA expressing plasmid transfection in vivo by pericardial injection results in decreased CaN Aβ protein expression of small part of myocytes, and CaN Aβ mRNA only shows decreased trend. The dosage of non-viral vector and the parameters of ultrasound energy should be optimized in further study.

结论RNAi技术抑制CaN Aβ基因表达可有效减轻Ald诱导的心肌细胞肥大程度；CaN Aβ基因中si1280(21bp)片段为实现RNAi的更有效片段；微泡+酶类心包腔内注射超声导入的方法可有效改善非病毒载体在体心肌的转染效率，同时具有一定的靶向性，但总的转染范围仍然有限；采用这一方法进一步进行&一肾一夹&心肌肥大模型大鼠在体心肌细胞的CaNAβ的RNAi干预，发现心肌肥大大鼠心外膜下局部心肌细胞CaN Aβ蛋白水平降低，CaN AβmRNA水平虽有下降趋势，但无统计学差异，提示质粒的用量及超声导入的参数有待进一步研究使其优化。
