Undergoing these two tectonic events, central-southern Ningxia had been incorporated into the thrust wedge of the northeastern Qinghai-Tibetan plateau, and the reason for this thrust wedge extending to the northeast may be the remarkable uplifting of the northern part of Plateau at the same time which resulted in the taper angle of the wedge over the critical value and made it spread forwards. The Cha-Gu fault was once similar to the present Haiyuan fault as the deformation front, and the development of the whole of northeastern plateau was not forward-breaking, but expended with out-of-sequence.
宁夏中南部并入到青藏高原东北缘逆冲构造楔之中，该逆冲构造楔中新世向北东扩展的原因可能是由于高原北部在同期显著的隆升运动使得逆冲楔顶角超过临界值，而向前扩展的，查-固断裂是早期类似于目前海原断裂的青藏高原变形前缘，整个高原东北部的扩展并不是前展式，而是一种没有特定顺序的变形。
Mould Design of Multi Taper Sound Absorbing Rubber Wedge
多锥体橡胶吸声尖劈模具的设计
The tapered waveguide performs mode transformation between optical fiber mode and polymer waveguide mode by using a refractive index taper and a width taper with wedge profile.
提出并设计了一种基于电光聚合物的锥形波导，可用于单模光纤与电光聚合物波导器件之间的连接。
Wedge mechanism was adopted in piercing die to achieve side piercing, and the positioning of taper pipe depended upon the conical surface of blanking die itself.
在冲孔模中选用了带有楔角的斜楔机构来实现侧冲，并利用冲裁凹模自身的锥形面实现了锥形管的定位。
