The experiment results show that SP-frames have lower coding efficiency than P-frames and significantly higher coding efficiency than Ⅰ-frames, and provide functionalities that usually unachieved with P-frames, at the same time greatly reduce bit cost.

从实验结果可知，SP帧的编码效率尽管略低于P帧，但却远远高于Ⅰ帧，而且提供的功能P帧是不具有的，同时大大降低了码流开销。

However, in the absent of LEF-2, the formation of viral nucleocapsid derived from lef-2 ko bacmid appeared to be normal under transmission electron microscope, suggesting that the life cycle of lef-2 ko bacmid could proceed through DNA replication to viral pakckaging unimpededly.

虽然病毒之复制受到lef-2基因缺失的影响，但由於病毒之构造蛋白仍可表现，如鞘蛋白(VP39)等，因此经由穿透式电子显微镜观察，可知缺失lef-2之病毒仍可有正常的核酸蛋白鞘形成。
