    摘要: Disclosed is a method for separating and purifying Ginkgolide C from root bark of ginkgo. The method comprises: (1) extracting the root bark of ginkgo with ethanol; (2) concentrating the resulting extract under vacuum to remove ethanol; (3) separating the concentrate by macroporous resin column chromatography; (4) after the concentrate being loaded on the column, washing the column with pure water to remove impurities, and then eluting the column with an ethanol solution; (5) concentrating the eluate under vacuum to dryness to obtain a yellow crude extract; (6) heating the crude extract in water to boiling to form a solution, and then refrigerating the solution; (7) concentrating the supernatant solution and filtering under vacuum to obtain a mixed crude crytal of ginkgolides; (8) dissolving the crude crystal in ethanol to form a supersaturated solution, refrigerating and crystallizing the solution to remove Ginkgolides A and B; (9) concentrating and recrystallizing the mother liquor to obtain a crystal of Ginkgolide C; and (10) recrystallizing the crystal with ethanol several times to obtain a high-purity crystal of Ginkgolide C.

    摘要: A microelectronic die including a CMOS ring oscillator thereon, and a method of using the same. The microelectronic die includes: a die substrate; and a plurality of CMOS ring oscillators on the die substrate, the ring oscillators being disposed at regions of the die substrate that are adapted to exhibit differing strain responses to package-included stress with respect to one another. A method of determining mechanical stress on a die which includes providing a die substrate in a CMOS ring oscillator on a die substrate. A frequency counter is coupled to the ring oscillator to measure a frequency of the ring oscillator to generate a frequency data signal therefrom. The frequency data signal is used to determine the mechanical stress on the die at a location of the ring oscillator.

    摘要: A micromachined strain gauge comprising a plastically deformable piezoresistive microstructure formed on a surface of a substrate so that deformation of the substrate plastically deforms the microstructure to thereby change the resistance of the microstructure. The stress in the substrate can be determined from the change in the resistance of the microstructure.
