Precisely cast ductile iron gear has advantages of low noise, high abrasion resistance index and long service life.(精密鑄造球鐵齒輪，噪音低，耐磨度高，使用壽命長。)

And reinforced high-strength lightweight concrete beam is less ductile as compared with the normal-weight concrete beam of the same concrete strength.(純彎段無腹筋的高強(qiáng)輕集料鋼筋混凝土梁在破壞時(shí)表現(xiàn)出較強(qiáng)的脆性，延性要比同一強(qiáng)度等級(jí)普通混凝土梁略差。)

The descending rock is substantially cooler than the surrounding mantle and hence is less ductile and much more liable to fracture.(下降的巖石比周圍的地幔的溫度低很多，因此延展性較小，更容易斷裂。)

However, in case of ductile materials they cause poor surface finish and low tool life.(可是在塑性材料加工時(shí)，造成表面光潔度和刀具壽命低。)

In these cases, the cracks can propagate to the critical length and result in ductile fracture of the component.(出現(xiàn)這種情況后，裂紋的長度會(huì)擴(kuò)展，造成部件延展斷裂。)

When the crystal size is about three nanometers (billionths of a meter), the material has its ultra-strong and ductile characteristics.(當(dāng)晶體大小大約為3納米（1納米等于10億分之一米）時(shí)，天然絲材料具有超強(qiáng)的強(qiáng)度與延展性特征。)

The isothermal quenching process of the ductile iron camshaft was analyzed.(對(duì)球鐵凸輪軸的等溫淬火工藝進(jìn)行了分析。)

So it is necessary to determine the laser absorptivity of ductile iron.(因此，確定球墨鑄鐵材料對(duì)激光的吸收率十分必要。)

Isothermally quenched ductile iron (austempered ductile iron, ADI) is a relatively new material to engineering industries.(等溫淬火球鐵(adi)對(duì)工程界來說是一種相對(duì)較新的材料。)

Till the bridge you will need be formed, till the ductile anchor hold.(直到架起你需要的橋，直到下定你韌性的錨。)

The Roman law..has proved extremely ductile and accommodating.
