模式分布 meaning in Chinese
pattern distribution
Examples
- In the photoluminescence ( pl ) spectra , a new emission band due to the exciton - exciton collision process ( p band ) is observed under low excitation intensity at room temperature . and some fine structures origination from the cavity modes of the fabry - p rot etalon could also be seen clearly
在单根zno微柱（直径有25 m ）的p带发光峰上还可以观察到明显的f - p腔模式分布，通过计算得到其腔长为21 m ，同微米柱的尺寸相当。 - 2 . according to distribution characteristic of recipes , a recipe fuzzy cluster algorithm based on kernel - function was presented . firstly one recipe kernel - function was defined to represent recipe class , through minimizing all the distance of recipe samples to recipe class kernel , recipe samples were classed . the class number was gave out and each recipe was gave membership degrees belong to each classes
2 、根据配方的模式分布特点，提出了一种基于类核函数的配方模糊聚类算法，定义一个配方类核函数来代表配方类，通过最小化所有配方样本到配方类核距离加权和来对配方进行聚类，得到聚类数目及模糊隶属度矩阵。 - In present studies of fgesl , the theoretical models usually neglected the contribution of external cavity and fiber grating to the phase condition , and considered the mode distribution of fgesl is in accordance with the mode distribution of ld without fg external cavity . obviously , such process method deviates from the physical facts
在已有的对fgesl的研究中，所采用的理论模型均忽略了光纤光栅( fg )的反射相位及光线在外腔中的往返相移对模式分布的影响，认为fgesl的模式分布跟没有fg中文摘要外腔时ld的模式一致，这种处理方式显然违背了物理事实。 - In this dissertation , the varied characteristics of soi rib waveguide were investigated , and the calculated results as well as simulated plots in theory were presented . it was the first time that a 3d overlap integral method was used to calculate the transition loss between the rib waveguides and the slab waveguides , in which the effect of the mode distribution in rib waveguides on the coupling efficiency was taken into account
针对上述问题，本论文对soi波导的各种特性进行探讨并给出了详细的计算结果，首次用三维功率交迭积分法计算了soi波导器件中波导过渡区的损耗，这种方法考虑了脊形波导模式分布对过渡区耦合效率的影响。
