楼主的问题，分成两部分：
1、一看楼主引用的语言，就为楼主感到可惜，感到悲哀，感到愤怒：
〖当1kg工质通过一定的界面流入热力学系统时，储存于它内部的
热力学能u当然随之进入系统，同时还把后面的流动功pv带劲了
系统，因此系统引进1kg工质而获得的总能量就是u+pv〗
这是什么痞子编的书？尽是物理概念不清，文痞气息恶劣的人渣语言！
什么是工质？尤其是什么是流动功？
PV 是流动功？如何解释流动功？如何把流动功翻译成英文？
归根结蒂：
这两个痞子编者，其实鬼混到了连焓 enthalpy 的本质根本搞不懂，
胡扯 PV 是流动功。随便翻翻任何中文教科书，把 PV 说成是体积
功，已经是匪夷所思，误导至极。
这两个痞子编者更是变本加厉、以讹传讹，荒诞无耻，败类到了极致！
看看鬼子是怎么踏踏实实叙述这些概念的吧，再来看看这些靠民脂民膏
喂肥的败类学者，165年前的基本概念，迄今还停留在信口雌黄的地步！
有这些败类学者存在的一天，这些混混教师只要有一天没有被扫进历史
山洞永远封禁，永远与人类，尤其是与教学永久隔离，我们的莘莘学子，
就别指望有不被恶意误导的可能！！就别指望没有学术堕落！人渣泛起！
A、The enthalpy is an extensive property. This means that, for homogeneous systems, the enthalpy is proportional to the size of the system. It is convenient to introduce the specific enthalpy h =H/m where m is the mass of the system, or the molar enthalpy Hm = H/n, where n is the number of moles (h and Hm are intensive properties).
B、
Enthalpy is the amount of heat content used or released in a system at constant pressure. Enthalpy is usually expressed as the change in enthalpy. The change in enthalpy is related to a change in internal energy (U) and a change in the volume (V), which is multiplied by the constant pressure of the system.
Introduction
Enthalpy (H) is the sum of the internal energy (U) and the product of pressure and volume (PV) given by the equation:
H=U+PV
When a process occurs at constant pressure, the heat evolved (either released or absorbed) is equal to the change in enthalpy. Enthalpy is a state function which depends entirely on the state functions T, P and U. Enthalpy is usually expressed as the change in enthalpy (ΔH) for a process between initial and final states:
ΔH=ΔU+ΔPV.
If temperature and pressure remain constant through the process and the work is limited to pressure-volume work, then the enthalpy change is given by the equation:
ΔH=ΔU+PΔV.
Also at constant pressure the heat flow (q) for the process is equal to the change in enthalpy defined by the equation:
ΔH=q.
C、
For a gas, a useful additional state variable is the enthalpy which is defined to be the sum of the internal energy E plus the product of the pressure p and volume V. Using the symbol H for the enthalpy:
H = E + p * V
The enthalpy can be made into an intensive, or specific , variable by dividing by the mass. Propulsion engineers use the specific enthalpy in engine analysis more than the enthalpy itself.
B、在二楼，还是三楼、四楼做热力学实验，对实验没有丝毫影响，
但是它们的宏观万有引力势能却是不一样的。
如果宏观机械能转化为分子内能，就必须考虑、必须计算。
3、热力学的理论已经建立了几百年了，我们的一大批酒囊饭袋的教授学者们，
浪费了人民的大量血汗，糟蹋了成堆的纳税人的钱。迄今为止，无法登堂
入室，学术毫无建树，连理解理论的最基本概念能力都远远远远不具备！
依然在、也只会在，最最最基本的概念上，胡搅蛮缠！
这就是它们这帮痞子学者的德行、德性！
这也是我们的集体悲哀！！
