This device has a spindle 5 detachably connected to the wheel of a travelling wheel 3 of a car, a support arm 6 oscillatably connected to the spindle, and a measuring wheel supported rotatably by the support arm. Provided to the support arm 6 are a vertical load generating mechanism for applying a vertical load to be added to the self weight of the measuring wheel 8, a first detection unit for detecting the vertical load that is applied to the measuring wheel from the road surface, a rotation transmission mechanism for transmitting to the measuring wheel the rotation of the spindle so as to provide a circumferential velocity difference between the travelling wheel and the measuring wheel, and a second detection unit for detecting the rotational resistance incurred by the measuring wheel from the road surface. The road surface friction coefficient is calculated with a computing unit based on the self weight of the measuring vehicle including the detected values of these detection units and the arm.

摘要： The invention relates to a method and an apparatus for determining the size or the size distribution of fine particles. A single particle or a group of particles are shone by a parallel polarized beam of a single wave length and the scattered intensity on the plane of polarization of the incident beam is measured by a photodetecting array. For a single particle the size is determined from the peak scattering angle at which the profile of the product of the scattered intensity and the scattering angle has the peak. On the other hand, for a group of particles, the size distribution is determined from the angular variation of the scattered intensity or the profile of the product of the scattered intensity and the scattering angle measured on the plane of polarization of the incident beam. For fine particles mixed with large particles the scattered intensities on the plane at a right angle to the plane of polarization measured by another photodetecting array is used to improve the accuracy of size determination of the fine particles.
