Only if diploid cell was in somatic cells, it would appear in PMCs.
体细胞中存在二倍体细胞是性细胞中出现二倍体细胞的前提。
You can specify the events for the first four PMCs by selecting the event group.
通过选择事件组，可以为前4个PMC指定事件。
PURPOSE: To observe the clinical effect of treatment of primary molar teeth with extensive defect using prefabricated metal crowns (PMCs).
目的：观察金属成品冠修复乳磨牙大面积缺损的疗效。
So, in multiplexing mode, hpmcount and hpmstat control the PMCs to collect events of different event groups in different time slices in turn.
因此，在多路模式中，hpmcount和hpmstat控制pmc，让它们在不同的时间片中轮流收集不同的事件组。
The nucleolus and chromosomes were connected with the MN filament network. The uniformity of nuclear MN changed with the development of the PMCs.
结果发现，花粉母细胞核内存在粗细不等的微梁骨架，与核仁和染色体紧密相连，随着发育的推移，其均一性发生改变。
There are three approaches to evaluating performance using PMCs from a low level to a high level: the raw PMC event, metrics, and the CPI breakdown model.
使用PMC评估性能有三种方法，从低级到高级依次是：原始pmc事件、指标和CPI细分模型。
The results showed that 4.53% of PMCs contained at least one unpaired of chromosomes and 2.31% of PMCs had a chromosome number deviating from their normal Numbers.
结果表明，4.53%的细胞含有至少一对不配对的染色体，2.31%的细胞里，染色体偏离正常的数目。
