The result showed that there was no expression in the normal control group and an apparent expression of ERK1/2 and Elk in the asthma group. A rather dense expressing of ERK1/2 was at bronchiole and mucous membrane, sub mucous membrane, smooth muscle, cytoplasm and nuclei of the out layer of the smooth muscle cell and an expression of positive fiber at submucous membrane.

结果发现正常肺内没有发现ERK1/2和Elk的表达，而哮喘时肺内有明显的ERK1/2和Elk表达，ERK1/2较密集表达在小支气管和细支气管的粘膜层、粘膜下层、平滑肌层和平滑肌外层细胞的胞浆和胞核中，也可见粘膜下层有阳性纤维表达。

However, more perfect structure of PEO segments is formed when the system exits in semicrystalline-semicrystalline state.3 When the composition of hard segments is 30%, the crystallizability of PETsegments exerts strong influence on the nucleation mechanism and growthdimensions of soft segments.

PEO嵌段的晶体尺寸小，结构不规整，结晶度低；当体系处于结晶—结晶态时，PEO嵌段的晶体结构比较规整，而且此时软段长度对其形态影响也比较大。3硬段含量为30％时，它的结晶与否直接影响软段晶体的成核及生长方式。

In autumn,there were GTH1 cells and GTH2 cells in GTH cells. A large number of secretory granules in GTH1 cells were circumnuclear; In GTH; cells cytoplast,there were two types of secretory granules,small circle and large circle, in small number.Structure of STH cells had no obvious changes.

秋季，在GTH细胞中发现GTH_1和GTH_2两种细胞，GTH_1细胞具有大量的分泌颗粒，并呈围核分布，GTH_2细胞胞质中具有数量较少的小圆形分泌颗粒和大圆形颗粒；STH细胞的结构无明显变化。

But the bump resistance is quite small compared with the resistance of the metallization traces. Therefore, daisy-chain structure cannot detect the slight changes in microstructure in the solder joint.

在铝、铜等金属接点中，孔洞的成核与成长皆可利用电阻的变化来坐标定与观测，可是对焊锡接点而言，焊锡接点的电阻远较一般的金属导线与接点小，所以以往研究电迁移效应时所用的雏菊花环结构无法感测到焊锡电阻随微结构产生的微小变化。
