Under a row of five coiled spring housebells a curvilinear rope, stretched between two holdfasts athwart across the recess beside the chimney pier, from which hung four smallsized square handkerchiefs folded unattached consecutively in adjacent rectangles and one pair of ladies' grey hose with Lisle suspender tops and feet in their habitual position clamped by three erect wooden pegs two at their outer extremities and the third at their point of junction.

42那是一排五个家用螺形弹簧按铃，下面，在烟囱那凹进去的间壁两侧的两个钩子之间，弯弯地横系着一根绳子，上面挂着四块对折的小方手绢：一块挨着一块，彼此并不重叠，呈长方形。另外还有一双灰色长统女袜，袜帮是用莱尔棉线织的，脚脖子以下是通常的样式。两端各用一个木制直夹子夹起，第三个夹子则夹在胯间重叠的部分。

It is an uncontinuous plane between the grey gneisses and Jingangku formation complex undergone later many strong deformations, especially the near-horizontal ductile shearing.

在恒山和五台山区大体上金岗库岩组的不同岩性或层位与灰色片麻岩相接触，受到后期多次强烈的构造改造，特别是近水平的韧性剪切使二者之间呈一不连续面，年轻的表壳岩覆盖在老片麻岩系之上，属剥离断层性质，应为低角度的大型正断层。
