The limited sensitivity of present pulsar surveys and the greater frequency drift make the more distant pulsars difficult to observe.
目前脈沖星普查的有限探測靈敏度和大的頻率漂移，使我們難以觀測到更遙遠的脈沖星。 -
The models currently used are either modified from low voltage mos models or based on macro model of simple polynomial established dddmos drift region resistance, both of which are limited and cannot provide a globally accurate physical model
業界目前使用的模型只是在低壓mos模型基礎上作一些修改，或者通過用簡單多項式的形式建立dddmos漂移區電阻的宏模型以建模。 -
This theoretic model employs the basic idea of correlation measurement, achieve the density wave speed by the correlation of the signals of upper and lower sensors, and get the total flow rate and water cut through the theoretic relationship of density wave speed and total flow rate as well as holdup with the help of drift flux model so as to accomplish the oil / water two - phase flow measurement at last, using the limited available experiment data, the theoretic model has been simplified into an applicable linear alternative which is suitable to homogeneous oil / water two - phase flow measurement to accomplish the oil / water two - phase flow measurement using the density wave phenomena is of highly theoretically valuable for density wave theory research as well as oilavater two - phase flow measurement research. to develop new type oil / water two - phase flow instrumentation based on this theoretic measurement method will be very applicable and promising
在此基礎上，針對穩態密度波理論提出了基於密度波理論的油水兩相流測量理論模型，該模型以密度波傳播理論作為基礎，通過上下游傳感器信號相關獲得密度波傳播速度，利用密度波傳播速度與總流量以及持相率的理論關系結合漂移模型來求解總流量和含相率，實現油水兩相流的測量，在理論分析的基礎上，在實驗資料有限的條件下，對基於密度波理論的油水兩相流測量理論模型作了極限的簡化，提出了本文油水兩相流測量理論方法應用在測量均勻油水兩相流中的實用線性模型。 -
