Rock climbers descend the spire of Tricouni Nail in the Needles of South Dakota Black Hills.

攀岩者在南达科他州的像针尖一样陡峭的黑山顶上攀岩而下。

Vaporisation from the needle on initial entryof the syringe into the injector, before the syringe plunger is depressed, can result in partial loss of high boiling components.

当注射器针尖插入后，在压下注射器塞杆之前，会引起组分的损失。
