A bipolar chirped optical code division multiple access ( OCDMA) schemes, based on a linear chirp fiber Bragg grating and fiber delay line, is proposed in this paper. 提出了一种基于线性啁啾布拉格光纤光栅和光纤延迟线的正负啁啾编码光码分多址(OCDMA)方案。
Centrosome duplication is a key requirement for bipolar spindle formation and correct segregation of chromosomes during cell division. 中心体的正常复制对于细胞分裂时双极纺锤体的形成、染色体的正确分离是至关重要的。
The base-band bipolar optical code division multiple access ( OCDMA) system is introduced, with transform of unipolar-bipolar and bipolar-unipolar, transmission of signal with bipolar codes is realized through unipolar medium. 基带双极性光码分多址(OCDMA)系统,采用码的极性转换思想,实现在考虑信道非理想下的单极性信道中传输双极性码。
It maintains genomic stability by establishing the bipolar spindles during cell division and executes accurate segregation of chromosomes during mitosis. 它通过在细胞分裂时建立双极纺锤体、在有丝分裂期执行精确的染色体分离而保持基因组稳定。
