Finally, by studying on using saw blades with different matrices cutting different stones, a basic compatibility rule about matrices and stones was concluded, say, when cutting a hard, high quartz and high alkalifeldspar content and strong bonded stone, a high impact strength and low wear-resistance matrix should be chosen; otherwise, when cutting a soft, low quartz or no quartz content and weak bonded stone, a high bending strength, low impact strength and high wear-resistance matrix should be chosen.

最后，通过对不同性能结合剂的锯片切割不同石材的切削寿命和磨损状态分析，得出了锯片结合剂性能与岩石性质之间的一般性匹配原则：即对于坚硬的、高石英含量的花岗岩，宜选用高强度、高冲击韧性、低耐磨性和对金刚石具有良好粘结性能的结合剂；对于低硬度、无石英或低石英含量的易切削花岗岩，宜选用高强度、高耐磨性和低冲击韧性的结合剂。

Results No any changes on fragrant pig skin in low and middle corticosteroid using group; but on skin of strong and super strong corticosteroid using group, macule and pigmentation appeared after 50 days of spreading.

结果：用低强度和中等强度药物的香猪在涂药期间及停药后皮肤未见明显变化，高强度组和超高强度组在用药50天左右皮肤上可见毛细血管扩张，并出现色素沉着斑；用药30天后表皮变化不明显，但黑素细胞出现上移现象，用药35天后上皮开始变薄，黑素细胞增多并上移。

The calculating results are compared with the test data in available literatures and FEM results. The research results show that the plastic hinge model is precise and correct, which can satisfy with the actual engineering demands. The collapse pressure of perforated liner casing decreases with phrase angle, initial ovalization and diameter-thickness ratio increasing, and increases with the yield stress. The phrase angle and initial ovalization have greatly influence on the collapse pressure. The collapse pressure of perforated liner casing is slightly changed with the diameter and density of perforation when the diameter and density are smaller than 12mm and 120 shots per meter, respectively.

计算结果表明：筛管抗挤强度的塑性铰模型具有很高的计算精度和准确度，可以满足工程实际需要；筛管抗挤强度随着射孔相位角、径厚比和初始椭圆度的增加而降低，随着屈服强度的增加而增加，相位角和椭圆度对筛管抗挤强度影响比较显著；在射孔直径小于12 mm、射孔密度小于120 孔/ m 时，筛管抗挤强度随射孔直径和射孔密度增加变化不明显。

For exploiting international rolled steel market farther, the weldable high strength reinforced bar were developed according to Canada standard.

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。
