In this system,the VVVF(variable voltage variable frequency) control method based on magnetic flux trajectory is applied.In the system,it is the target for the magnetic flux linkage polygon to be greatly approximate to the ideal magnetic flux circle.Considering such limitations as the low speed torque ripple,high speed real time and the working frequency of switching element,through the subsection synchronization control method by applying different numbers of magnetic flux linkage polygon for different frequency range,the perfect precision specifications for speed can be obtained.

系统采用基于磁通轨迹法的他控式变频调速方案，以磁链多边形尽量逼近理想磁通圆为目标，并考虑低速转矩脉动、高速实时性和开关元件的工作频率限制等约束条件，通过采用分段同步控制方式，在不同的频段采用不同的磁链多边形边数，使系统获得了优异的转速精度指标。

The dissecting of samples in group2 were difficult. The root of pulmonary artery and ascending aorta failed to be unfolded because fibrous tissue was tough, right and left fibrous trigone were too firm to be solved by hand. Cardiac muscle fibers couldn't be stripped along myofibrillar trajectory since they were prone to break because of their friability.

组2的心脏解剖困难，表现为纤维组织坚韧，游离肺动脉非常困难；徒手无法松解左、右纤维三角，肺动脉和主动脉根部的游离非常困难；心肌纤维坚硬、质脆，解剖时容易断离成碎块，无法沿纤维走行方向剥离。
