And the change of amplitude is bigger than that of frequence , either burich hills surface or internal phase and either fluid or gas in farcture 同时无论是潜山面还是其内幕,不管是裂隙中含流体还是含气体,振幅的变化量大于频率的变化量。
Then the sensitivity of amplitude to fracture of the buried hill ' s surface is further bigger than that to fracture of buried hill ' s internal phase 表明振幅比频率更对裂缝敏感。而且振幅对内幕裂缝的敏感性远大于其对潜山面裂缝的敏感性。
Pulse internal phase coding and pulse external quasi random frequency agile signal is a kind of complex signal which can avoid interference frequency band , increase system bandwidth , consequently increase the range resolution 本文所研究的脉内二相编码脉间准随机跳频信号是复合信号的一种,可以避开干扰频段,提高系统带宽,从而提高了距离分辨力。
In this thesis , the signal express format and characteristic of pulse internal phase modulation and pulse external frequency agile is introduced , and the signal design is processed based on the demand of radar system , the restriction of parameter design and various code format 本文首先介绍了脉内调相脉间跳频信号的表达形式和特点,并根据雷达系统的需求和参数设计的约束条件以及不同的编码形式进行了信号的设计。
Then , by seismic numericac simulating of the buried hill surface and its internal phase and analysis of characteristic of wave - field , the wave - field charalteristic of the buried hill ' s surface is different to the characteristic of the buried hills " internal phase , and the change of amplitude and frequence is bigger than that of velosity which proves further that dynamical characteristic is more sensitive to fracture than kinetic characteristic 进而通过潜山面和内幕地面地震记录的数值模拟和波场特征分析表明,潜山面和潜山内幕裂缝介质的波场特征是不一致的,振幅和频率的变化量大于速度的变化量,从而更进一步证明,对于裂缝的敏感性,动力学特征优于运动学特征。
Since viscosity of emulsion is important to elm separation process , it is necessary to research the viscosity of emulsion . during the study of separation of copper in the model industry waste by emulsion liquid membrane , some operating parameters are investigated , including the value of ph in the external phase , the concentration of acid in the internal phase , the concentration of copper in external phase , the concentration of surfactant , the kinds of carriers in the membranes phase as well as the concentration of carriers 对乳液膜体系分离铜离子的研究,主要是考察分离条件(如外水相的ph 、内水相酸的浓度,外水相铜离子的浓度,载体种类、载体浓度、表面活性剂的浓度等)对铜离子提取程度的影响,通过实验得到,外水相的ph值是乳液膜分离铜离子的一个重要原因,这主要是由于cu ( oh ) _ 2溶度积和界面反应的化学平衡决定的。
