With the development of computer science, more and more teachers are studying the possibilities of including this technology in their EFL teaching.
“New Horizon College English” is now adopted as the teaching material in most universities in China, and this system can be called an example of combination between technology and course plan.
Then he can study the material, watch the teaching video, participate in discussion with peer learners, and upload his exercise or project.

The additional axial force caused by the decrease of temperature is (1) Where α is the coefficient of thermal expansion of the tubing material (for steel, α=1.2×10-5℃); ΔT is the change in average tubing temperature, ℃; E is Young's modulus (for steel, ); Ac is cross-sectional area of the tubing wall, m2
(2) Ballooning Effect Similarly, the additional axial force caused by the ballooning effect is (2) Where ν is Poisson's ratio of the material (for steel, =0.28); ΔPi and ΔPo are the changes in average pressure inside and outside the tubing respectively, MPa; Ai and Ao are areas corresponding to tubing ID and OD respectively, m2
