| 6. | This shows , on the course of growth , the directional ability of the primary ( cr ) phase is not manifest , and must influence the morphology and distribution of the a phase and eutectic , gravely breach the continuity of the base
由此可见，初生相在其长大过程中，定向效果不明显，这将影响相和共晶体的形貌和分布，不利于获得具有纯cr纤维强化相。 |
| 7. | A large content of zn in az91 , which leads to the formation of ( mgzn ) 12re , is thought as the basic reason for a poor strengthening effect of az91 when re is added , compared with am50
由于azgl镁合金中的zn含量远高于am50中zn的含量，而形成了另一种强化相（ mgzfl ，这种稀土相耐热性能不如mglzre被认为是稀土对azgl合金力学性能改善的效果要比am50差的根本原因。 |

| 9. | The characteristic of stirring equipment is used a shaking sieve to disperse the adding pure fe or fe203 powder and used a combined stirrer instead of a common paddle stirrer to improve the shear effect to mixing melts . the particularity of fabricating process is the step of holding stirring at a constant high temperature . both of which can improve the even distributing degree of reinforcement phase in pure al matrix
搅拌设备的特殊之处在于使用了振荡筛分散加入粉末和更换组合式搅拌器来提高对混合熔体的剪切效果，工艺的特别之处在于一定温度下的保温搅拌过程，这二者均能提高强化相在纯al基体中的均匀分布。 |
| 10. | The amount of nb3si / nb5si3 increases , their morphology tends to be more regular , their distribution becomes more homogeneously with the increasing of withdrawing rate . the microstructure is better oriented along the longitudinal axis of the samples when the withdrawing rate is between 0 . 6 and 6 . 0mm / min . at the same withdrawing rate , the microstructure changes from the beginning part to the ending part of the samples
铌?硅基rmics材料原始铸态组织由初生nb基固溶体和在其间分布的nb基固溶体+硅化铌共晶团组成；随着抽拉速率的增大，定向凝固共晶组织中硅化铌强化相细化、数量增多、分布趋于规则和均匀，定向效果显著；在相同抽拉速率条件下，区熔试样的组织从起始段到终止段发生了改变。 |
