The results show that the density of gritstone is decreased gradually as the temperature increasing; so that it can be ignored; the longitudinal wave velocity is linearly decreased when the temperature increasing, and decrease rate of it follows the law of conic; R is one temperature point, which makes the law of tensile strength of gritstone after high temperature follows the law of parabola; and the maximal tensile strength appears when the operative temperature is R. After the temperature is higher than 700 ℃, tensile strength is small and change range is small when the temperature is increased.

结果表明，高温后粗砂岩的密度随试验温度的升高减小幅度很小，几乎可忽略不记；高温后试件中纵波波速的传播随温度升高基本呈线性降低，而减小率呈二次曲线规律变化；存在一个温度点R，使高温后试件的抗拉强度呈开口向下抛物线关系变化，且在R温度作用后试件抗拉强度达到最大；当试验温度大于700 ℃后，试件的抗拉强度变得很小，且当温度升高时变化幅度也很小。

For example,the graph in Fig.3-5 is Hamiltonian（a possible path being P→Q→R→S→T→P）but is not quite Eulerian,since any path which includes every dege exactly once（e. g.P→Q→T→P→S→R→Q→S→T）must end up at a vertex different from the initial vertex.

例如，图3-5所示是一个哈密尔顿图（存在一条路P→Q→R→S→T→P）但不是一个欧拉图，这是因为图中任何包含所有边一次且仅一次的路（如P→Q→T→P→ S→R→Q→S→T）都不能回到原出发顶点。

The results show that the ratio of the released elastic energy to the damage dissipative energy can be served as a sensitive precursor of catastrophe. Furthermore the value of the non-dimensional ratio has a similar tendency to be 1 with different responses in the two failure modes, that is, the response function R always decreases in the gradual mode, while increases and tends to be infinite at the catastrophic point of the failure.

研究发现在灾变性破坏和非灾变性的渐进式破坏两种失效模式中，虽然系统中卸载所贡献的弹性能增量与损伤消耗和释放的能量增量的比值都有趋向于1的趋势，但是两者的趋近方式不同：灾变性破坏时表征能量比随控制变量变化特征的响应函数R有一个上升段，在灾变破坏点$R$趋向于无穷大，而非灾变性破坏中$R$始终是减小的。

In this paper, we study syzygies of injective resolvent s and cosyzygies of injective resolutions, and probe the relationship of injective resolvent s and injective resolutions, and then prove that if R is a Noetherian ring with id≤n, then every left R-module has injective dimension at most n or ∞.
