The indentation loading curve with a spherical diamond tip was employed to determine the yield strengths and hardening indices of Cu films which were prepared on silicon substrates by different ways with the same thickness of 1. 5μm. The result showed that the yield strength of the Cu film depends on the deposition technology, and is much higher than that of the bulk material.

结果表明，在薄膜厚度相同的条件下，铜膜的屈服强度与铜膜的制备方法有关，选择IBED法较MS法可获得更高的屈服强度〓此外，由两种方法所镀制铜膜的屈服强度均远高于其体材，这与铝膜的情况相一致，说明薄膜与整体材料在强度方面存在显著差异的结论具有普遍性。

In this paper, based on the experimental studies, the effects of the ARC-3 glass fiber for the improvement of the flexural tensile and the unconfined compressive of the concrete are analysed. Further statistical relations between flexural tensile strength, volume ratio of fiber and curing time, and a mathmatical model of the flexural tensile is presented.

The behavior of unsaturated soils is complex, and determining its shear strengthparameters need expensive and high-precision instruments, and the test is also very difficult which need lots of time and effords, all those make the theory of unsaturated soil mechanics hard apply to the engineering practice. However, the total strength including suctional strength can also reflect the feature of unsaturated expansive soil strength, and is easy to be obtained.

由于非饱和土强度参数的获取需用到高精的设备，且试验难度大、费资耗时，妨碍了非饱和土理论在工程中的应用，而包含了吸附强度的总强度指标也能反映非饱和土的强度特性且易于获取。

The influence of recessing in adh es ive layer with high elastic modulus on the peak stress of joint is not evident so that it would improve the actual strength of joint markedly based on the load bearing ability not being affected evidenly . On the other hand , the recessing in the joint with low elastic modulus adh es ive caus es the peak stress es increase evidently that may decrease the nominal and actual strength of the joint markedly .

对胶层和被粘物中应力分布的数值分析结果表明：胶层中的间隙对接头端部的应力分布无明显影响，但对间隙附近的应力峰值影响较大；随着胶粘剂弹性模量的增大，间隙附近的应力峰值有所降低；对于高弹性模量胶粘剂接头，胶层中的间隙对接头的应力峰值无明显影响，在不降低接头名义强度的同时可使得接头的实际强度显著提高；而对于低弹性模量胶粘剂接头，间隙使得接头上的应力峰值明显上升，可能导致接头的名义强度和实际强度显著降低。

Through comprehensive comparison,during the growth from 1 age-degree bamboo to 2 age-degree bamboo,density, mechanical strength(except maximum tensile strength etc.),fraction of bundle sheath,cell wall ratio,crystallinity,cellulose content and lignin content increase rate are the greatest.3age-degree bamboo has higher strength,strength and gravity ratio andcrystallinity are the biggest,fraction of parenchyma is small and insect-resistant.2 degree bamboo has the greatest mechanical strength,but its strength andgravity ratio is not the highest and its crystallinity is lower than 3 age-degreebamboo due to its greatest fraction of parenchyma,loss tangent value is thebiggest.Its creep character is not good and is easily eaten by moth.

通过综合比较，竹材从1度竹到2度竹生长过程中，密度、力学强度、纤维束比量、胞壁率、结晶度、纤维素含量、木质素含量等指标增加幅度是最大的。3度竹强度较高，强重比、结晶度最高，薄壁组织含量较小，相对抗虫蛀，材质最好，适合材用。4度竹结晶度下降引起强度的下降，但薄壁组织组织比量最小，相对最抗虫蛀。2度竹力学强度最大，但是强重比并不是最大，结晶度比3度竹低，由于薄壁组织组织比量最大，内耗值最大，蠕变性能较差，同时相对易遭虫蛀。
