RZCOCA¹¹²⁷⁴⁵BNC²³⁶²¹³⁺¹ 基本例句 n.归零点¹⁰⁰ A format conversion from a non-return-to- zero NRZ signal to return- to-zero RZ signal is presented based on four- wave mixing FWM and cross- phase modulation XPM in a silicon optical waveguide. 基于硅光波导的四波混频 FWM和交叉相位调制 XPM效应,提出非归零码 NRZ到归零码 RZ的光调制格式转换。 opticsjournal Integrity and honesty are always guiding principles for RZ books. 日知图书始终坚持诚信待人的合作原则。 dooland Besides, it teems with famous Chinese medicine like Gastrodiae, Rz and Fritillaria thunbergii. 此外还盛产天麻、贝母等名贵中草药。 blog.sina.com.cn Besides, the limitation of RZ- DPSK regeneration utilizing self- phase modulation is discussed. The initial conditions using four- wave mixing to achieve regeneration is given. 同时对于 RZ- DPSK信号,研究了利用自相位调制实现再生的局限性,给出了利用四波混频实现再生的初始条件。 boshuo By analysing frequency spectrum in this paper, we can understand that when NRZ code be transferred into RZ code of1/2 mark-to- space ratio, the timing clock can be obtained at largest power. 本文通过对 NRZ、 RZ伪随机码序列进行频谱分析,得知当 NRZ码变换成码元占空比为1/2的 RZ码时,所提取出的定时时钟功率最强。 cnki Details, qualifications, more photos after the jump. Thanks to readers RZ, PA, JS, AR. 感谢读者 RZ, PA, JS以及 AR给我们提供了更多的细节、资料以及图片的链接。 yeeyan DIH is compared with three best existing heuristics, RZ, WY and FL, on1500 randomly generated instances. DIH算法与目前求解流水调度问题最好的启发算法 RZ、 WY、 FL在1500个实例上进行比较。 cnki Distance between such deviations amounts to only a relatively minimal multiple of their depth Rz, Rmax. 偏差之间的距离仅等于其深度的相对最小倍数。 cadjy.net Methods Orthogonal design was adopted. Extraction content of RZ volatile oil was used as the index for the optimizing of extraction process. 方法采用正交试验设计,以莪术油提取量为指标优选提取工艺; cnki So the idea of spherical coordinate is you're going to polar coordinates again in the rz plane. 所以说球坐标系,其实就是在 rz平面再建立一个极坐标。163 That's in line with the idea that we are just doing again, polar coordinates in the rz directions. 球坐标中的平面也差不多是这样了,只要把 rz看做极坐标就行了。163 The quality of the converted RZ signal is determined by that of the recovered clock and the NRZ signal, whereas hardly influenced by the gain recovery time of the SOA. 转换后输出的归零信号的质量仅由恢复的时钟信号和非归零信号的质量决定,受太赫兹光非对称解复用器中半导体光放大器增益恢复时间的影响极小。 cnki Utilizing phase modulator and dispersion compensation fiber DCF link, a non- return-zero NRZ data format is converted to return-zero RZ data format with tunable duty ratio. 提出了利用相位调制器和色散补偿光纤 DCF把非归零 NRZ码信号转换成为占空比可调的归零 RZ码信号的方案。 dictall |
