Abstract: The present disclosure discloses a tobacco leaf foliar spraying substance for reducing harmful ingredients in cheroot, a method for reducing carcinogenic components in flue-cured tobacco leaves and flue-cured tobacco shreds. The tobacco leaf foliar spraying substance contains a lotus leaf extract, the harmful chemical ingredients comprise N-nitrosonornicotine, 4-(N-methyl-nitrosamine)-1-(3-pyridinyl)-1-butanone, N-nitrosoanabasine and N-nitrosoanatabine. Foliar spraying is performed on a fertile field by using the lotus leaf extract before tobacco leaves are harvested and modulated, which not only significantly promotesagronomic characters and economic traits of tobacco and alleviates tobacco leaf browning but also effectively reduces harmful chemical ingredients unique to tobacco leaves, such as nitrosamine and nicotine.

Abstract: The present disclosure discloses a method for synthesizing quinolones intermediates by a continuous flow reaction. Specifically, according to the method, a microchannel reactor is used, which improves the selectivity and conversion rate of the reaction, and the conversion rate of compound ii is increased to more than 95% and the yield is increased to more than 85%; avoids the use of a solvent such as methanol, and methyl tert-butyl ether, etc., in the intermittent reaction process, which simplifies the post-processing method, shortens the overall operation time from about 24 hours to a few minutes, greatly improving the production efficiency, and realizing the continuity and automation of the whole process; and thus makes the product have high purity and high yield, which is suitable for industrial production.

Abstract: An L-shaped shear wall module including an L-shaped outer pattern plate, an L-shaped inner pattern plate, and connectors connected between the L-shaped outer pattern plate and the L-shaped inner pattern plate. The L-shaped outer pattern plate 100 and the L-shaped inner pattern plate 200 are arranged in parallel to each other. The L-shaped inner pattern plate includes a first inner pattern plate and a second inner pattern plate which are perpendicular to each other. A corner transition block is disposed at a corner of the L-shaped inner pattern plate. The corner transition block has a protruding surface protruding towards the L-shaped outer pattern plate. The protruding surface of the corner transition block and the inner surface of the L-shaped outer pattern plate jointly enclose a concreting cavity at the corners for concreting reinforced concrete. The present application also provides a shear wall and a construction method thereof.

Abstract: The present invention relates to the field of communication technologies and discloses a method and an apparatus for encoding a data address, so that attacks can be effectively prevented and resources and costs required to handle a bank conflict are reduced. In solutions provided by embodiments of the present invention, an exclusive-OR operation is performed on one or more bits of a received uncoded address by using multiple preset transform polynomials; and an encoded address is obtained according to a result of the exclusive-OR operation. The solutions provided by the embodiments of the present invention are applicable to designs that require a large-capacity DRAM, high performance and high reliability, and have an anti-attack demand.

Abstract: The present invention discloses a data caching method and apparatus, and relates to the field of network applications. The method includes: receiving a first data request; writing target data in the first data request into an on-chip Cache, and counting a storage time of the target data in the on-chip cache; enabling a delay expiry identifier of the target data when the storage time of the target data in the Cache reaches a preset delay time; and releasing the target data when the delay expiry identifier of the target data is in an enabled state and processing of the target data is complete.

Abstract: Embodiments of the present invention relate to a signal order-preserving method and apparatus. When data of a request signal that comes from a corresponding first upstream device is written into a first first input first output (FIFO) memory, invalid data is written into a second FIFO memory corresponding to a second upstream device in a same clock cycle; and the data of the request signal is read from the first FIFO memory, the invalid data is read from the second FIFO memory, the invalid data is discarded, and the data of the request signal is conveyed to a downstream device. Through the signal order-preserving method and apparatus in the embodiments of the present invention, the coupling extent between devices on which there is an order-preserving requirement is reduced while signal order-preserving is achieved.
