摘要:
The present invention relates to a system for measuring a sample pore using a computed tomography (CT) and a standard sample and to a method thereof, more particularly to a system for measuring a sample pore using a computed tomography (CT) and a standard sample and to a method thereof, wherein the number of pixels in the count range of a cross-sectional image of the measurement sample and the number of pixels corresponding to the gray level range of the pore are calculated with reference to the count range utilized in the cross-sectional image of the standard sample and the gray level range of the pore so as to accurately measure the porosity of the measurement sample after performing a CT scan of the standard sample and the measurement sample together using a CT scanner.

Disclosed is a sample storage apparatus in that a multilayered rotary table is formed in a liquid nitrogen vessel, so that a plurality of sample storage boxes is stored in the multilayered rotary table, whereby it can effectively and maximally ensure the space for storing the samples. The sample storage apparatus includes: a rotating axis 100; a rotary table 200 having an upper cylinder portion 210 protruded upward from an upper middle portion thereof and allowing the rotating axis 100 to be inserted therein and a lower cylinder portion 220 protruded downward from a lower middle portion thereof and allowing the rotating axis 100 to be inserted therein; at least one partition member 300 for partitioning off an upper surface of the rotary table 200 formed at the upper surface of the rotary table 200; a fixing member 400 coupled to one side of an outer circumference of the lower cylinder portion 220 through a hinge coupling portion 410 and having a lower portion protruded downward from a lower end of the lower cylinder portion 220 and a slanting portion formed at one side of an upper end thereof so as to form a fixing gap angle 430; and a latching member 500 formed along an outer circumference of the upper cylinder portion 210 and having a plurality of insertion holes 510 for allowing a lower end of the fixing member 400 to be inserted therein.

摘要:
A computed tomography apparatus for geological resource core analysis, more particularly to a computed tomography apparatus for geological resource core analysis in that it can conveniently utilize a computed tomography apparatus for industrial use, the movement between the CT beam transmitter and the detector is decreased, thereby performing an accurate measurement and breaking down infrequently, and especially, it can easily perform a CT scan on a cylinder type (or rod shape) sample having a very long major axis such as a geological resource core sample.

Disclosed is a low-irritant, high-performance composition for permanent waves. It comprises L-cysteine or a mixture of L-cysteine and L-acetylcysteine as a reducing agent, for breaking disulfide bridges of cystines to form cysteines; L-arginine for swelling keratin fibers to facilitate deep invasion of the reducing agent into the keratin fibers; and a citrus peel powder or extract, containing peptides for promoting growth of dermal papilla cells and D-limonene for preventing depilation, and optionally with histidine for regenerating the hair, a powder or extract of green tea leaves for exerting an astringent effect on a scalp, chlorella for exerting an anti-bacterial and deodorizing effect on the scalp, a powder or extract of cactus for preventing a horny tissue from being generated on the scalp or desquamating upper layers of dead skin cells from the scalp, and polyquaternium or Hydroxyethylcellulose as a viscosity-inducing substance, whereby the human hair can be healthily changed from waves to straight or vice versa within a short time without irritation to the skin and the scalp and the formed curls can be prolonged with elasticity.
