A slipped disc occurs when the jelly-like disc of cartilage that acts as a cushion between two vertebrae in the spine, slips or prolapses so it is pressing on the nerves causing the muscles of the back to go into spasm.

椎间盘脱出是由于脊柱两块椎骨中的起缓冲冲击作用的胶状椎间盘软骨发生滑动或脱垂时，压迫椎管内神经引起后背痉挛。在严重的情况下椎间盘软骨不得不通过手术的方法移走，在一些情况下脊柱的骨头被熔合了避免进一步的移动。

Long Throttling Lip on the disc retards flow when seating position is approached. Disc chattering is prevented, and wiredrawing of seating surfaces is reduced.

长节流唇位于阀瓣上，当流体接近阀座密封位置时可以阻止减速流体，从而防止阀瓣颤动，减轻阀座密封面的拉丝现象。

The utility model relates to a machine for selling children's toys, comprising a coin-storing barrel, a thing-storing chest and a dial-rotation mechanism. The dial-rotation machanism is rotated and pushes a barrier chip after a coin is inserted. Hence, a gear is smoothly rotated to rotate a rotary disc in the thing-storing chest. When a groove slot on the rotary disc is matched with a through slot on the thing-storing chest together, the toys in the groove slot is dropped out via the through slot and a groove channel.
