Scientists predicted that the gas would have a high temperature and so it would primarily emit low-energy X-rays. But its very low density made observation difficult.
科学家们预言气体温度可能很高于是会主要发射出低能的X射线。但是其过低的密度给观测带来困难。
The same period, the ocean thermal slow, relatively high temperature, air density changes smaller solipsism relative area of low pressure.
同一时期，海洋散热较慢，温度相对地较高，空气密度变化较小，遂形成相对的低压区。
The existing density compensator model does not fit high temperature and pressure saturated vapor, the density compensator precision is low and causes big error in saturated vapor measurement.
现有的密度补偿模型不适合高温高压饱和蒸汽的流量测量，密度补偿精度较低，导致蒸汽流量测量误差较大。
