Only little differences in the frequency range under 1 MHz at different current peak values (Fig. 14 and Fig. 15) can be noticed except from some resonance frequencies.
除了几个谐振频率,在1兆赫兹以下的频带,干扰信号在不同峰值电流下测试出来的结果仅有微小的差别(图14和图15)。
Currently, magnetic resonance imaging (MRI) is used 1-3 months after treatment to evaluate anatomical tumor response, based upon changes in tumor size and contrast-agent enhancement.
目前,人们基于肿瘤大小和对比剂增强变化之原理,在治疗后1 - 3个月时,用磁共振成像(MRI)来评估解剖学上的肿瘤反应。
Applying the modified extended tanh-function methods, many types of new explicit traveling wave solutions of the (2 + 1) dimensional long wave-short wave resonance interaction equations are obtained.
利用扩展的双曲正切函数法获得了(2 + 1)维长波短波共振相互作用方程的多组新显式精确行波解。
And an important thing to remember when we talk about resonance hybrids is that the structure it's not 1/2 the time this structure, and 1/2 of the time this structure, it's actually some combination or some average between the two structures.
而当我们讨论共振杂化的时候,有一件重要的事情需要牢记,那就是这种结构并不是,一半时间处于这种结构的状态,而另外一半时间又变成了这种结构的状态,它实际上是两种结构在,一定程度上的组合或者平均。
But since in drawing Lewis structures actually, in some cases you do, you can draw a dotted line that means a 1 and 1/2 bond, but most in most cases, we just draw out both resonance structures, and the way that we say it's a resonance structure is that we put it in the brackets and we put an arrow between it.
但是由于在画路易斯结构时,其实,在某些情况下是可以的,你可以画一条虚线来表示一又二分之一键,但是在多数情况下,我们就把两个结构都画出来,而我们说这是一个共振结构的表示的方法是,把它们放在括号里,并在中间放一个双箭头。
