在跟踪之后，垃圾收集器就识别软可及的对象——这些对象上除了软引用外，没有任何强引用。
After the trace, the collector identifies the softly reachable objects — these objects for which no strong references exist but soft references do.
处理软引用之后，弱可及对象的集合被识别——这样的对象上不存在强引用或软引用。
After processing the soft references, the set of weakly reachable objects is identified — objects for which no strong or soft references exist.
弱可及对象(weaklyreachable)：不是强可及对象也不是软可及对象，并且能够通过弱引用访问的对象。
Weakly reachable: an object that is not strongly or softly reachable and can be accessed through a weak reference.
软可及对象(softlyreachable)：不是强可及对象，并且能够通过软引用访问的对象。
Softly reachable: an object that is not strongly reachable and can be accessed through a soft reference.
虚可及对象(phantomly reachable)：不是强可及对象、软可及对象，也不是弱可及对象，已经结束的，可以通过虚引用访问的对象。
Phantomly reachable: an object that is not strongly, softly, or weakly reachable, has been finalized, and can be accessed through a phantom reference.
根据几个模型相加可提高模型的预测精度及鲁棒性的思想，提出了一种非线性软测量建模的新方法。
Inspired by the idea of combining models to improve prediction accuracy and robustness, a new method for nonlinear soft sensing modeling of chemical processes is proposed.
介绍了用硅橡胶和聚氯乙烯两种材料制作工艺品及精铸蜡模的可剥软模具的制作方法及其实际应用。
This paper introduces the making method of the strippable soft dies of handiworks and precision casting wax patterns which are made of the silicic rubber and PVC and its practical application.
因此，将岩石可切割性划分为软、中软及中硬三个级别，对掘进过程中岩石的可切割性进行识别。
So the rock cuttabilities are divided into three levels as soft, medium soft and medium hard, based on which the rock cuttabilities along the tunnel is recognized.
