此外,分析了出现TBSS但未降雹的原因,找出了TBSS配合垂直液态水含量密度(DVIL )和45 dBz 伸展高度、TBSS 配合回波宽度和45 dBz 伸展高度的预报冰雹的方法,在出现TBSS特征的回波中,上述方法的预报准确率分别...

简单讲,能量密度指特定食物量中的卡路里(能量)含量。
Simply put, energy density is the number of calories (energy) in a specific amount of food.
振动式密度计以其结构简单、能稳定、确度高、量密度范围宽且样品种类广等特点,成为工业过程中最常用的一种在线密度计。
Being simple, stable and accurate, the vibration type densitometers have been widely used in industrial processes for on line measurements of different kinds of samples and a wide range of density.
含盐量较低的地表水密度较低,因此下沉和搅动深水的可能性较小。
Less salty surface waters would be less dense and therefore less likely to sink and stir up deep water.
So, for example, we have this average level, and then it can go high where we have the peak, or it can go very low. We can also discuss sound waves, so again it's just the periodic variation of some property -- in this case we're talking about density, so we have high density areas and low density areas.
例如这是平均位置,在峰的位置水位高,在谷水位低,我们也可以,讨论声波它也是某种,量的周期变化,在这里我们,讨论的是密度,我们有高密度区和低密度区。
