Our numerical results reveal that the uniform pre-stretch strongly affects the phase separation patterns, and leads to preferential growth in the tensile direction.

数值模拟结果表明，有限预拉伸控制组分畴的生长方向，引导 图案沿预拉伸方向优先生长。有限预拉伸的强度越大，条纹的宽度和间距越小。

Surface morphologies and microstructures of the whisker were characterized by using SEM, HRTEM and SCXD. The preferential growth orientation of the whisker was determined to be along its direction.

通过SEM、HRTEM及SCXD等表征手段，对晶须的表面形貌和微观结构进行了分析，并确定其生长方向为晶须的方向。
