查询词典 tough and tensile

The deformation mechanism is mainly the single-slip and cross-ship, the fracture mechanism is mainly the congregation of transgranular micro-hole, and large uniform deformation occurred before tough fracture, and therefore, the ability of plastic deformation and the mechanical properties of the material were remarkably improved. These fully indicate that the new melt-treatment developed in this work is an effective and advanced technique, and further testify that the improvement of metallurgical quality of the material is the key to enhance its mechanical properties, especially its plastic deformation performance. The results of tensile and compression tests at elevated temperature also indicate that the suitable hot-working temperature range is 400～450℃. 4. A steady-state plastic flow exists during the plastic deformation of the aluminum sheet used for pressure can at elevated temperature. A hyperbolic sine relationship can be satisfied between the steady-state flow stress and strain rate by introducing an Arrhenius term which involves some thermal activation parameters, i.

压力罐用铝材中的主要冶金缺陷为Al〓O〓夹杂物、气孔及富Fe杂质相；高效熔体处理显著改善了材料的冶金缺陷的存在形态，使含杂量明显减少、夹杂物尺寸变细小且分布均匀，富Fe杂质相变为细小、分布均匀的团球状或短棒状的复杂化合物，同时也明显细化了结晶组织；此外，由于高效熔体处理有效地减少了材料中裂纹萌生源数量，因而改变了材料的塑性变形微观过程及断裂方式，主要以单滑移和交滑移进行塑性变形，断裂方式为穿晶微孔聚集型，韧性断裂前产生了大量的均匀变形，不易出现变形失稳，从而显著提高了罐用铝材的塑变能力和力学性能。

Bring along the tough And tensile stick of hope, pick up the firm packsack of patience.

你要带上"希望"这根坚韧的拐杖和"忍耐"这个结实的旅行袋。

In 2003, a piece of strange meat without the bones and organs was drifted up the nearby seabeach of the Monte Port in Chile. This piece of meat is 12 meters in length and 13 tons in weight. 80 years ago, people found a piece of strange meat of 5 to 7 tons on the seabeach of Florida, U.S.A. When people tried to cut it, it was so flexible, tough and tensile that it broke actually the knife.

2003年，一种没有骨骼和器官的怪肉被冲上智利蒙特港附近的海滩，长12米，重13吨。80年前，人们在美国佛罗里达州海滩也发现了一块重5到7吨的怪肉，当人们试图将它割开时，它坚韧而富有弹性的外皮竟把刀片弄断了。

The mechanical properties of the modified material were tested, and the thermal stability of the modified EP blend was also investigated by TG. The results indicate that the graft copolymerization between PU and EP effectly inforces the miscibility of the PU/EP system. Compared with the properties of pure EP, the impact strength and tensile strength of the PU/EP with high thermal stability are markedly enhanced, and the fracture surface of the PU/EP system displays tough fracture features.

研究结果表明：PU和EP分子链之间存在着化学接枝反应，能有效地改善PU/EP体系中PU和EP分子间的相容性及相互贯穿；与TDE-85与E-51的混和环氧树脂比，PU改性TDE-85与E-51的混和环氧树脂仍然具有很强的耐热性能，并且冲击强度、拉伸强度均获得显著提高；PU/EP体系断口裂纹呈明显的韧性断裂特征，说明TDE-85与E-51的混和环氧树脂PU改性增韧效果明显。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
