凝胶的SEM照片可见,海藻酸钙的冷冻干燥颗粒内为较大的圆孔,海藻酸锌凝胶内为较小的长孔,表明海藻酸锌高分子链在凝胶颗粒中的体积分率相对较大同时刚性较强;卵清蛋白从海藻酸凝胶颗粒中释放的试验结果表明,由于上述海藻酸锌凝胶的特性,导致海藻酸锌对卵清蛋白扩散阻滞作用相对较强;根据试验数据计算得卵清蛋白在海藻酸钙、海藻酸锌凝胶颗粒中的扩散系数分别为1。

The bigger average pore of the porosity system,the smaller size of the micro-residual oil droplet and the more dispersed micro-residual oil droplet after waterflooding, that is to say, when the average pore width is big enough,the micro-residual oil is mainly composed of isolated single-pore and dual-pores droplets whereas the blocklike remaining oil is hardly exist.

微观驱替效率随平均孔宽的增加而增加,孔隙大小决定微观剩余油液滴的大小,孔隙系统的平均孔隙半径越大,水驱之后微观剩余油的尺寸越小,分布越分散,也即当孔隙的平均孔宽较大时,微观剩余油主要是由孤立的单孔隙和双孔隙液滴组成,连片的块状剩余油几乎不存在。

And for the stress in the directional direction, which is imposed on the lathe-bed, the bending plane is an epiplastron, therefore, the batten wall pore should be designed in the epiplastron.

而当孔的位置是位于弯曲中性轴附近的时候,其对弯曲刚度的影响比较小,而当其远离中性轴即靠近边缘的时候,对弯曲刚度的影响就越大,所以应该将板壁孔布置在弯曲中性轴附近,这样可以减少孔对床身刚度的影响。

对铸造过程充型模拟的计算结果可知,在气道附近区域,流体流动的速度梯度很大,容易出现卷气、冲刷砂芯等现象,因此,在这些区域出现气孔、针孔和缩孔、砂孔等缺陷的可能性很大,为此,必须保证铸件凝固补缩良好、排气通畅。
