| 7. | Some interest has been generated in studying the rationale for assisted hatching . some reports suggest that embryos with lower zona pellucida thickness ( zpt ) and higher zona pellucida thickness variation ( zptv ) had a better chance of successful hatching and so the patient become pregnant ; another reports suggest that in vivo aging ; in vitro culture and exposure to ultralow temperature may induce zona hardening and then impair the embryo ability of hatching
有作者提出胚胎透明带厚度( zonapellucidathickness ， zpt )小的胚胎孵出时阻力减小，而透明带厚度变化率( zonapellucidathicknessvariation ， zptv )高的胚胎由于透明带上有一个明显薄的区域而使胚胎易于孵出；还有作者推测病人年龄、体外培养天数的增加及冷冻处理会增加透明带的硬度，使胚胎孵出困难。 |
| 8. | It was revealed that elastomer or filler had its strong point as modifier of pp . at the same matrix ligament thickness l , improvement of toughness by elastomer was obviously higher than that of caco3 , while adding caco3 increased the modulus , hardness and heat deflection temperature of pp
0刀9匆m人指出用弹性体和无机刚性粒子作聚丙烯的增韧剂各有所长，在相同基体带厚度l下，弹性体提高韧性的程度明显高于c3co3 ， c3co3则使聚丙烯的模量、硬度和热变形温度等明显提高。 |
| 9. | The impact behaviors of pp / eoc and pp / caco3 were compared . the toughening mechanisms of pp / eoc and pp / caco3 systems are firstly proved to agree well with wu ' s percolation theory . the essential condition occurring brittle - tough transition in two binary systems is that the matrix ligament thickness ( l ) is lower than the critical matrix ligament thickness ( lc ) which is approximate to 0 . 095 ? m
比较ppffioc和ppcacos二体系的增韧行为，发现加入eoc和cacos都能增韧pp ，首次验证了新型弹性体eoc和无机刚性粒子cacos增韧pp的机理符合wu氏逾渗理论，二体系发生脆韧转变的基本条件是基体带厚度l小于临界基体带厚度人（ 。 |
