下降的岩石比周围的地幔的温度低很多，因此延展性较小，更容易断裂。
The descending rock is substantially cooler than the surrounding mantle and hence is less ductile and much more liable to fracture.
零件表面能被低熔点金属渗透以增大密度、强度、硬度、延展性和抗冲击能力。
A part surface can be infiltrated with a low melting point metal to increase density, strength, hardness, ductility and impact resistance.
溶胶-凝胶法制得的有机-无机杂化材料通常显示低弹性模量、高延展性及高机械强度。
Organic-inorganic hybrids synthesized by sol-gel process usually exhibited low elastic modulus, high ductility and high mechanical strength.
