So the external work in the irreversible adiabatic expansion process is less than that in the reversible adiabatic expansion process, but not the expansion work.

终压相同时，可逆绝热膨胀过程对外所作的功等于膨胀功，不可逆绝热膨胀过程对外所作的功小于膨胀功，其对外所作的功仅是膨胀功的一部分，是排斥大气所作功与有用功之和，故不可逆过程对外所作的功小于可逆过程的膨胀功，而不是其"膨胀功"小于可逆过程的膨胀功。

The design method is described, and the calculation results are presented under the standard air conditioning condition. The working process of the two-stage expander is discussed, and the difference between the two-stage expander and the conventional one is stated. In addition, the influence of the dip angle on the expansion chamber volume is analyzed. The results show that the dip angle has little effect on the expansion chamber volume and it is suggested that the effect may be neglected in the expander design.

The tensile strength of CPE vulcanizates modified by in situ formed NaAA and LiAA is more than 30MPa and 28MPa, respectively.

原位合成丙烯酸盐改性CPE硫化胶在电解质水溶液中的吸水膨胀率比在去离子水中低得多，浓度越高这种效应就越强烈；温度提高可使硫化胶的吸水膨胀速度提高，在常温到60℃之间，吸水膨胀率随着温度的提高而增大，但超过60℃平衡吸水膨胀率则随着温度的提高而降低；硫化胶的吸水膨胀过程并不是单一的菲克扩散，其中还包括聚丙烯酸盐和橡胶分子链的松弛。

The results show that, with the expansion cone angle remaining unchanged, the sizing length of expansion cone does not have much effect on the residual stress of casing after expansion, but it has much effect on the expansion force required by tube expansion. The expansion cone angle has no effect on the maximum residual stress of casing, but it has remarkable effect on expansion force. When the radial component force of expansion force is greater than the material's tensile strength, the damage to the material will arise.

研究结果表明，在膨胀锥锥角保持不变的情况下，膨胀锥定径长对膨胀后套管的残余应力没有太大影响，但对套管膨胀所需要的膨胀力有较大影响；膨胀锥锥角对套管最大残余应力没有影响，但对膨胀力的影响十分明显，当膨胀力的径向分力大于材料的抗拉强度时，材料将发生破坏。
