求助，我们老师上课讲的特定要素模型，谁能帮我解释一下，总觉得老师讲的不太对，以下是老师课件上的文字与图片，图片在附件里， 谢谢！

[size=110%]The lower and up halves represent the H-O and SF models respectively.
[size=110%]
Assume: K is sector-specific in short-run but perfectly mobile in long-run. Give price ration, the economy is long-run equilibrium at B1(lower panel) initially, drawing the VMPL curves in the 2 sectors(up panel), point A1
determines the wage rate.

[size=110%]An increase in price of good 2 in short-run moves the equilibrium to A2(up panel), K allocation remains unchanged so that B1
moves to B2(lower panel). At A2, w has risen in terms of good 1. Returns to K in short-run rises in sector 2 and falls in sector 1.
[size=110%]In the intermediate run, capital reallocates itself from sector 1 to sector 2, causing L relocating. As sector 1 is K-intensive,
it sheds less L per unit-K than sector 2. w rises further,and is accompanied by a decline in k in each sector(as price is fixed in adjustment).
K/L ratio in both sectors rises, implying a B2-B1 adjustment path.
[size=110%]At new equilibriums, A3 and B3, wage has risen while return to K equalized once again across sectors, has fallen in terms of both go ods.
