Abstract: The present invention discloses a hemming-stitch-free warp-knitted elastic fabric and a method for knitting thereof. The method includes: making a non-elastic yarn pass across a guide needle of the first guide bar and form the surface of the fabric by knitting via two needles or three needles in a 1×1 or 2×1 warp plain stitch loop mode, and making an elastic yarn pass across a guide needle of the second guide bar and form the inside of the fabric by knitting with the aforementioned non-elastic yarn in the same direction via three needles in a open double warp plain stitch loop mode, and two loops are continuously formed on each course of the open double warp plain stitch loop. The hemming-stitch-free warp-knitted fabric produced according to the present invention has good snagging grade, moderate horizontal straight tensile force and good resilience.

Abstract: A near-infrared (NIR) quality monitoring method used in column chromatography for extracting conjugated estrogens (CEs) from pregnant mare urine (PMU), that includes steps of: collecting an eluate obtained from column chromatography of a PMU stock solution as a to-be-tested sample; subjecting the to-be-tested sample to near-infrared spectroscopy (NIRS) to obtain raw spectral data, eliminating abnormal spectral values from the raw spectral data by a Mahalanobis distance method based on L1-PCA, and importing spectral data obtained after the abnormal spectral values are eliminated into a correction model to obtain a CE content in the to-be-tested sample; the correction model is a linear equation illustrating a relationship between true values and measured values, and the measured values refer to the NIR spectral data obtained after the abnormal spectral values are eliminated; and the CEs comprise one or more of sodium 17?-dihydroequilin sulfate, sodium equilin sulfate, and sodium estrone sulfate.

Abstract: The present invention provides a free-cut warp-knitted elastic fabric and a method for production thereof. The method uses a first guide bar and a second guide bar of a tricot warp knitting machine for knitting, wherein a non-elastic yarn passes across a guide needle of the first guide bar and forms the surface of the fabric by knitting via two needles in a 1×1 warp plain stitch loop mode, and an elastic yarn passes across a guide needle of the second guide bar and forms the inside of the fabric by knitting with the aforementioned non-elastic yarn in the same direction via two needles in a 1×1 double warp plain stitch loop mode. Finally the fabric which has good resilience, can be arbitrarily cut, and has low raveling property, good elasticity and high snagging level is obtained.

Abstract: A wind-power generation system with an over-speed protection is disclosed. The system is provided to convert wind energy into mechanical energy by a wind turbine, and mechanical energy is converted into electric energy by the wind turbine driving a generator. Also, electric energy is delivered to a power grid. The wind-power generation system mainly includes an AC crowbar, a fuse, and a DC chopper. The AC crowbar or the DC chopper is provided to consume superfluous energy outputted from the generator, thus providing an over-load operation to brake the wind turbine when the wind turbine operates under a first stage over-speed operation. Finally, the generator is isolated from the generator-side converter by disconnecting the fuse when the wind turbine operates under a second stage over-speed operation.
