Jack stared at Tony, his voice soft steel: "As long as you can."
杰克盯着托尼，他的声音不高，却像钢铁一样坚定：“有多久拖多久。”

The rotor, made of soft steel without an exciting winding, may have two, four or six poles.
用软钢制作而成的转子没有励磁电枢，但有两个，四个或者六个电极。

As an example, the results of soft steel under the ocean corrosive circumstance are compared with that when they are free of corrosion.
还以软钢为例，对其在海洋腐蚀和未腐蚀条件下的结果进行了比较。

With the severity of crack problems increasingly of structures, which are made up of soft steel, to study diagnosis, control, and maintain of the crack, is a new hotspot in fault diagnosis areas.
随着由低碳钢构成的机械承载结构裂纹问题的日益严重，研究机械承载结构裂纹诊断、控制与维修已成为故障诊断学领域的新热点。
1. 低碳钢（low carbon steel）是碳含量低于0.25%的碳素钢，因其强度低、硬度低而软，故又称软钢。 低碳钢包括大部分普通碳素结构钢和一部分优质碳素结构钢，大多不经热处理用于工程结构件，有的经渗碳和其他热处理用于要求耐磨的机械零件。低碳钢退火组织为铁素体和少量珠光体，其强度和硬度较低，塑性和韧性较好。因此，其冷成形性良好，可采用卷边、折弯、冲压等方法进行冷成形。这种钢还具有良好的焊接性。含碳量从0.10%至0.30%低碳钢易于接受各种加工如锻造，焊接和切削，常用于制造链条，铆钉，螺栓，轴等。
