4096 free nuclei ( actual counting, 3733& 4224 ones) are produced through 12 times of repeated divisions of the functional megaspore, then cell walls appear among the free nuclei and cellular female gametophyte is formed. 福建柏起作用的大孢子,经过12次连续有丝分裂后,产生4096个(实际计算为3733&4224个)游离核,而后在核之间形成雌配子体胞壁。
The functional relations between nucleus number, general interaction star number and general local mean free path and distance for normal, anomalous, and total nuclei in projectile fragments are calculated. 计算出了射弹碎片中正常核、反常核及二者之和的数目、广义作用星数、广义局域平均自由程等与距离的函数关系。
