C The profile is of berm, which the section below the berm is concave. Using the polynomial curve to fit the shapes of the mean profile, the exponential equation of the equilibrium beach profile in South China was established, which has a general form: y=〓+ C. 2 It's obvious for the beach processes to vary with seasons. The main variation processes of beach profiles are composed of four kinds of mode which are the equilibrium profile mode, the berm mode, the foreshore mode and the bar mode. 3 Beach systems of the arc-shaped coast in South China exhibit an wide range of morphologic and dynamic variability with respect to both time and local environment.

将金融状况指数FCI引入我国货币政策体系，得到结论央行不适宜对资产价格因素进行过度关注，只适合在关注通胀和产出的前提下，对资产价格因素给予一个微弱的考虑，因为央行福利损失值随资产价格干预度的加强呈现"J"型曲线。

The relationship between elastic strain energy and the reduction coefficient can be used as criteria in slope stability analysis using strength reduction method.

研究结果表明：采用强度折减法，当边坡处于稳定状态时，折减系数增大引起边坡变形增大，导致边坡体弹性应变能随之增大；但是，边坡岩土体能够承受的弹性应变能是有极限的，当折减系数增大到某一值时，边坡体的弹性应变能达到极限，再增大折减系数将导致边坡失稳破坏；边坡体弹性应变能与折减系数服从指数关系；利用弹性应变能与折减系数关系曲线得到的边坡安全系数与采用其他经典的方法所得边坡安全系数基本一致，弹性应变能随折减系数变化而变化的规律可以作为边坡稳定性强度折减法分析的失稳判据。
