在此之后，他们对多少病毒粒子恢复活性进行计算。结果发现，接受治疗的细胞内恢复活性的病毒粒子数量处于完全无法探测的水平，相比之下，未接受治疗的细胞却处于可探测状态。
Then they counted how many virus particles were reactivated, finding completely undetectable levels in the treated cells versus detectable levels in the untreated cells.
病毒粒子经1％醋酸铀负染后镜检，病毒粒子分为有囊膜和完全或部分失去囊膜两种。
The viral particles, negatively stained with 1% uranium acetate, observed under transmission microscope, appeared to be enveloped or unenveloped because of the envelope being damaged.
