However, it is not known how orthodontic force influences the function of cementoblast and what is the relationship between the function change of cementoblast with root resorption. So we studied the effect of mechanical stimuli on root resoption by examining the expression OPG and RANKL and exploring the related signal transduction pathway in cementoblast. Methods: Cementoblasts OCCM30 were cultured in DMEM with 10% FBS for 48 hours and starved in DMEM with no FBS for 24 hours, then subjected to mechanical strain by four-point bending system with tension and compression stress at 2000μstrain at 0.5Hz frequency. The flow cytometry was used to examine the cell cycle and proliferation activity after 3h, 6h, 12h, 24h loading respectively. OPG and RANKL mRNA were analysed with real time quantitive RT-PCR after the same loading period as FCM.

频域内多点效应与时域内有不一致的地方，即对于240米高的超大型坝，对于竖向永久位移最大的坝顶部位和损伤值原本就比较高的坝顶及斜坡部位，频域内多点输入比单点输入的永久位移和损伤值反应要大些。

The Multi-Point Effect in frequency domain is studied, and the analytical procedure is simplified to some extent, that is, the responding data is accurate enough only with the input according to the first four degressively arranged eigenvalue of earthquake power spectrum matrix.

对于240米高的超大型土石坝，相关程度越小，坝顶竖向永久位移和易破坏单元的损伤值越大，当竖向与水平向地震动强度接近时，这一规律更明显。时域和频域内这一规律是一致的。

Generally, Toft's"strategic interaction"is relatively new and explanative. Being an important starting point for this research, Toft's"strategic interaction"perspective still leaves us with some questions: Firstly, Toft's analysis on the four types of strategy is too far-fetched; Secondly, Toft deliberately evades the question of a strategic choice in his theoretical model; thirdly, the argument"time is conducive to the weak rather than the strong side"is not convincing.

总体上看，托夫特的&战略互动论&比较新颖且有相当的解释力，因此也构成了本研究的重要起点，但它也还是给我们留下了几点重要的疑问：首先，托夫特关于四种战略类型划分过于牵强；其次，在其理论模型中，托夫特有意地回避了战略选择的问题；再次，关于&时间有利于弱者而不利于强者&的逻辑解释也并不能令人信服。
