pfb的翻译

It is shown that the viscous shear-heating of PFB provides a thermal energy source for positive temperature-anomalies and results in the enlargement of PFB-affected width by heat conduction.

研究表明，塑性流动网带黏性剪切热的产生为温度的正异常提供了热源，并通过热传导扩展网带的影响范围，形成相应的热异常网带。

The term PFB and its poorer sibling the Neglected Subsequent Children ( NSCs) were coined by members of the parenting website Mumsnet.

PFB（宝贝老大）和可怜的弟弟妹妹即“被忽略的老小”（NSCs）这两种说法是育儿网站“Mumsnet”的成员创造的。

It has been reported that PFB can improve the properties of flow, heat and mass transfer in fluidized bed. However, the complex bed behavior is more difficult to study.

气固脉动流化床是在普通流化床的基础上加入脉动气流，文献中报道了其可以改善普通流化床的流动及传质传热特性，但流化床内更为复杂的流动状态，使得研究变得更加困难。
