0 a curved piece of cartilage inside a joint (= place where two bones are connected) of the body such as the knee -- 半月板（膝盖等关节处的软骨组织圆盘）
1 on a liquid, a surface that curves either out or in as a result of surface tension -- （表面张力形成的）弯液面
In this solution, the meniscus extends from the contact line to form a sheet with a free surface parallel to the plate.
The results presented here determine the critical speed for the validity of these solutions for a plate and a meniscus in a channel.
The critical speeds determined experimentally for a receding meniscus in a tube are considerably smaller than those obtained here for a meniscus in a channel.
First a profile of the meniscus is chosen, either by an informed guess or on the basis of the previous iterations.
The normal-stress iterative scheme used to determine the meniscus profile is as follows.
The flotation fluid in each centrifuge tube was topped up ten times to form a positive meniscus.
Subsequently, samples were allowed to settle for at least 15 min during which eggs migrated to the top of the meniscus.
They examined a number of ad hoc boundary conditions at the meniscus for the nearly rectilinear steady flow and the resulting stability criterion.
