Motor test sample of ocean-sand mixing shall be compared type Ⅰ cement with type Ⅱ cement, to make use of type Ⅱ cement to motor test sample of ocean-sand mixing shall have more compressive and bending strength about 10%, Rising of strength is best among non-standard sand mixing.
若添加炉石於海砂所拌和的水泥砂浆,其抗弯强度会随著炉石添加量的增加而增加,以40%~60%的炉石替代量为最佳;以第Ⅰ及第Ⅱ类型所拌和的海砂水泥砂浆试体做比较,依晚期强度而言,第Ⅱ类型水泥所拌和的试体,其抗压及抗弯强度比第Ⅰ类型水泥约高出10%左右,其中以非标准砂所拌和的试体强度上升最大。

The modal tests of PCB and PCB assembly (free boundary condition and fixed boundary condition) were carried out. The equivalent elastic modulus and damping parameters of PCB can be gained, and the fixed boundary condition of finite element model was also determined. These will help to the following work.Second, drop impact tests of three different heights were carried out. Strains and acceleration responses of PCB were measured. Failed BGA packages of different test conditions were dyeing, and cross section analysis of failed solder joints was conducted.

Second, drop impact tests of three different heights were carried out. Strains and acceleration responses of PCB were measured. Failed BGA packages of different test conditions were dyeing, and cross section analysis of failed solder joints was conducted. It was found in our drop tests that the root cause of lead-free solder joints under drop impact was the combined effect of mechanical shock and PCB bending vibration.

Participants required more time to shift their focus over the imaged stimulus in the KBR paradigm. More fixations,more saccades,and rarer saccade distance were found when they scanned in the KBR task.Detailed analysis showed that participants scanned the whole distance from the original point to the target point in KBR paradigm,while the scanning distance were much shorter in FP paradigm.
在距离相同的情况下,被试完成KBR任务需要更多的时间,眼动特征表明,被试在完成KBR任务时,需要更多的注视点、眼跳次数和更远的眼跳距离,对眼动轨迹图的分析显示,完成KBR任务时,被试进行的是从初始点到目标点的全程扫描,而完成FP任务时,扫描距离较短。
