The invention relates to the field of cosmetic filling materials, in particular to a sodium hyaluronate gel lubricating liquid, a filling agent and a preparation method and application thereof.The sodium hyaluronate gel lubricating liquid comprises a sodium hyaluronate solution, polycaprolactone microspheres are evenly dispersed in the sodium hyaluronate solution, alkali liquor is added into the polycaprolactone microspheres and sodium hyaluronate dry powder, and the sodium hyaluronate gel lubricating liquid is obtained. According to the sodium hyaluronate gel, the polycaprolactone microspheres and the sodium hyaluronate solution are matched, so that the concentration of the polycaprolactone microspheres which are finally injected into the sodium hyaluronate gel of a human body is controllable and can be always kept consistent, and the sodium hyaluronate gel can be used for preparing the sodium hyaluronate gel. Therefore, the continuous time and the continuous stability of the filling effect in the human body can be kept, and meanwhile, the pushing force in the injection process can be reduced on the premise of keeping a good injection effect, so that the injection can be more easily injected into the human body.

A method of calibrating a device for measuring the concentration of creatinine in a sample including one or more enzyme modulators, the device comprising an enzyme layer, the method comprising: determining sensitivities of the device for each of one or more calibration solutions; determining a degree of modulation for the sample to be measured, determining a degree of modulation for each calibration solution; wherein said determining of each of the degrees of modulation comprises estimating the concentration of an enzyme modulator in the enzyme layer of the device; and calculating the sensitivity of the device for the sample, wherein the said calculating comprises adjusting the sensitivity of the device for each calibration solution by a factor comprising the determined degrees of modulation of the sample and the calibration solution.

The invention discloses a high-compact bidirectional adjustable concrete and application, which comprises the following parts: 1% PII 52.5, 0.20-0.35% II-grade low-calcium coal ash, 0.05-0.08% wollastonite, 0.015-0.020% high-property polycarboxylic acid additive, 0.0012-0.0020% polypropylene fiber, 2.00-0.32% medium sand, 1.40-1.70% crushed stone, 0.38-0.45% water and 0-0.016% concrete accelerator. The invention is fit for spraying and casting on the large-smooth curve, which satisfies quality standard.

The invention provides a long-persistence luminous enameled plate. A glaze used for sintering the long-persistence luminous enameled plate comprises following components in part by mass: 15 to 30 parts of long-persistence luminous powder, 80 to 95 parts of vanadium pentoxide enamel, 5 to 15 parts of tourmaline, 60 to 120 parts of organic additive and 0.2 to 5 parts of dispersant. The long-persistence luminous enameled plate has the main advantages that: (1) because vanadium pentoxide is added into the enamel, the firing temperature is reduced, the high-temperature viscosity is reduced, the enamel serving as a base with low melting point and high transparency can be manufactured, the enamel can be melted at the lower temperature (less than 550 DEG C), the long-persistence time and the luminous brightness of the luminous powder can be greatly kept because the enamel does not produce solid-phase reaction with the long-persistence luminous powder, and the persistence time can reach over 6hours; and (2) the mixed slurry is evenly sprayed on an iron plate by using electrostatic spraying equipment, so the evenness of the mixed coating is greatly improved, the controllable enamel with even thickness can be manufactured, and the glaze of the product has good gloss and has no bubble, sinking and crawling and other defects.

The invention discloses a DDR-based reading data synchronization method and system. The method uses a frequency divider to input a data strobe signal half-inpu-dqs-n as a DDR interface DQS signal, a sampling clock internal-clk serves as a sampling clock in a DDR controller, a transition clock is set up as a synchronous clock between the DDR interface DQS signal and the sampling clock in the DDR controller, and the synchronous clock achieves the synchronization of the sampling clock in the DDR controller and an input color outside the DDR and achieves asynchronous transmission of DDR interfaceDQS domain data and domain data of the sampling color in the DDR controller. According to the method and the system, the building time and the retention time of a DQS domain and a sampling color domain in the DDR controller can be satisfied to the maximum extent, the synchronization problem of the DDR reading data is solved with a very small delay, and the method and the system no longer rely on the FIFO technology.
