以30日龄仔猪睾丸组织块为培养对象，应用飞利普TECNAI10电子显微镜对培养前后的生精细胞类别进行了观察，对培养后的组织块进行生精细胞分化程度鉴定，建立了仔猪睾丸组织生精细胞爬片体外培养模型。

There are two stages: rough adjustment and careful adjustment. During rough adjustment: the laser optical axis is considered as the normal axis of measurement optical path, and the coaxal measurement system is established. During careful adjustment: the tilt coefficient of WYGO interferometer is considered as the adjustment standard to adjust the objective, so the actual result of the object surface quality is ensured.

调整分为粗调和精调两个阶段，在粗调阶段，以激光的光轴作为检测光路的基准光轴，建立起共轴光路检测系统；在精调阶段，以WYGO干涉仪内部倾斜系数作为调整依据，进行物镜的精调，从而保证检测结果反应真实的物镜面形质量。
