A surface analysis apparatus and a method for compensating for mechanical vibrations and drifts in a surface analysis instrument are disclosed. A probe that is sensitive to the distance between the probe and a sample surface provides a probe signal. The probe signal contains information about the surface properties and noise due to changes in the probe-surface distance. A sensor measures a displacement between a probe and the sample surface. The sensor is substantially insensitive to the surface properties measured by the probe. The displacement measurement can be used to compensate for the noise in the probe signal.

Disclosed is a sanitary napkin which is allowed to quickly absorb menstrual blood and also effective in preventing absorbed menstrual blood from returning to the skin-side surface under pressure and in concealing the color of absorbed menstrual blood from the outside. Between a liquid absorbent layer and a topsheet formed of a resin film having a large number of liquid passage apertures, there is disposed a large number of barrier members having a small width. The barrier members are strips formed of a resin film, and gaps are left between adjacent barrier members. After passing through the liquid passage apertures of the topsheet, menstrual blood tends to be absorbed by the liquid absorbent layer through the gaps. The barrier members also function to prevent liquid return and conceal the color of menstrual blood.
