Abstract: The present invention relates to a pharmaceutical composition for inhalation, comprising N-[2-[[[4-(2,2-dimethyl-1-oxopropoxy)phenyl]sulfonyl]amino]benzoyl]-(S)-glycinate sodium or a hydrate thereof, a pH adjuster, an osmotic pressure adjuster, and optionally a surfactant. The pharmaceutical composition for inhalation of the present invention can improve drug stability. After being atomized by an inhalation atomizing device, inhalation droplets can maintain good uniformity.

Abstract: A standard light source color matching observation box comprises a box body, the interior space of which forms an observation chamber. The top of the observation chamber is provided with a standard light source comprising a halogen tungsten lamp under which a light filter is provided. The top of the observation chamber is further provided with an LED light. The halogen tungsten lamp emits a light ray through the light filter to be mixed with the light ray of the LED light. The illumination energy provided by a narrow-wave LED light source occupies 20% or less of the total radiation energy. The quality of the compensated light source of the invention is lower than <0.2 A level according to the metamerism index specified by D illuminant of the CIE standard. An object to be measured undergoes a color measurement by the compensated light ray to ensure accuracy of long-time color measurement.

Abstract: The present invention discloses a method for performing color measurement using a standard light source color matching observation box. The method comprises: arranging a halogen tungsten lamp and a light filter in the color matching observation box for cooperation, wherein the light ray of the halogen tungsten lamp emits a main body radiation light ray through the light filter; arranging a plurality of narrow-wave LED light sources of different light-emitting wavelengths to emit a compensation light ray; mixing the main body radiation light ray and the compensation light ray in the color matching observation box into a mixed light ray that uniformly simulates a standard D illuminant; and performing a color measurement on a measured object in the color matching observation box by the mixed light ray.

Abstract: A method, combination or apparatus for compensating for or predicting the shift in the human perception of color which occurs when the color is seen on a small surface area as compared with when it is seen extending over of large surface area. The compensation or prediction is performed by increasing (compensation) or decreasing (prediction) the lightness and chroma of the color in a specified way. The invention allows choosers of color to take account of the shifts when making their choice of colors and is useful in choosing colors for paints, plastics, textiles or illuminated surfaces.
