1200mm and maximum ratio reached several thousands . cylindrical worm zc 可達數(shù)千圓柱蝸桿zc
The load factor is the maximum ratio of elements to buckets 加載因子是元素與存儲桶的最大比率。
The maximum ratio of pigment and linker of some pigments on water - based ink was determined by the experiment 通過實驗確定了水性油墨中幾種不同色相顏料分散、研磨的最大顏基比。
Polarization diversity and maximum ratio combining ( mrc ) is used to restrain the sharp signal fading in the telemetry systems , in which the object is in flight at a high speed and rotating and in low elevation 在信號極化衰弱現(xiàn)象嚴重的環(huán)境中對快速飛行目標、低仰角運動目標以及旋轉(zhuǎn)運動目標等進行遙測接收時,極化分集最大比合成技術可以有效的改善接收性能。
However , multipath components can be resolvable due to the autocorrelation of the spread spectrum signal , thus the optimal receiver equals coherent rake reception , i . e . maximum ratio combining the independent components which endure flat fading or frequency non - selective fading . synchronization of pn code and separation of resolvable multipath components need to estimate the exact time delay among the multipath components 但是利用擴頻信號的自相關特性,可分辨多徑可以被有效分離,最優(yōu)接收機等效為對多個具有獨立平坦衰落信道(或頻率非選擇性信道)特性的多徑信號進行最大比合并,即相干rake接收。
