The present invention discloses a centrifugal spinning apparatus, including a frame, a spinning device, a feeding device for providing a spinning solution to the spinning device, and a collection device for collecting centrifugal spinning fibers ejected by the spinning device. The collection device is horizontally disposed below the spinning device, to enable the centrifugal spinning fibers ejected by the spinning device to be attached to a surface of the collection device. A planar receiving-type centrifugal spinning automatic production device using the centrifugal spinning apparatus breaks through existing centrifugal spinning based on ring collection and centrifugal spinning technologies based on electrostatic collection, resolves a preparation problem of continuous filament of the centrifugal spinning, and achieves mass production of the centrifugal spinning. The whole production process is completed automatically without manual intervention.

Provided in the present invention are a geologically constrained infrared imaging detection method and system for an urban deeply-buried strip-like passage, pertaining to the crossing fields of geophysics and remote sensing technology. The method includes: establishing an urban hierarchical three-dimensional temperature field model according to urban street DEM data and geological data corresponding to urban streets; acquiring urban stratum geological background heat flux according to the urban hierarchical three-dimensional temperature field model; using a total solar radiation energy distribution model to calculate urban surface total solar radiation energy; sequentially filtering out the urban surface total solar radiation energy and the urban stratum geological background heat flux from an infrared remote sensing image of a region corresponding to a strip-like underground target, to acquire a perturbation signal image of an urban street deeply-buried strip-like passage; and using grayscale closed-operation plus an edge detection algorithm to perform detection and positioning after preprocessing the perturbation signal image of the urban street deeply-buried strip-like passage, to acquire location information of an urban strip-like underground passage. The present invention achieves inverse detection and positioning of an urban street deeply-buried strip-like passage.

A method to form yarn via film fiberizing spinning belongs to a textile technical field. A film cutting device is arranged behind each drafting system on a ring frame, whose cut resistance apron and cutting roller engage with each other to form a cutting zone to cut and fiberize the film to get belt-like multi-filaments. Then the multi-filament formed passes through the first, second and third drafting zones in sequence for drawing, in such a manner that the multi-filament molecular orientation and crystallization are improved. After being drafted, the multi-filaments are twisted into yarn by ring spinning, which provides a novel high-efficient and short-processing way of producing yarns of nano-micro fibers using films instead of conventional nano-spun fibers such as electro- and centrifugal spun fibers, thereby breaking restriction of 'low bulk and low-speed production of nano-spun fibers' and integrating the film industry with the textile industry.

A ring composite spinning method based on film filamentization is provided, which belongs to a textile technical field. According to the method, a film cutting drafting device is arranged above each drafting system on a ring spinning machine for cutting film material into ribbon-shaped multi-filaments to achieve the film filamentization, which changes a conventional formation of filament through linear spraying by spinneret orifices; then the multi-filaments formed pass through first and second filament drafting zones in sequence for drawing, so as to enhance and attenuate the multi-filaments. After in drawing, the multi-filaments are twisted with conventional staple fibers to form a composite yarn with high quality and functions, achieving one-step production of composite yarns of nano-micro fibers without online combination of nanofibers spinning and ring staple spinning, thereby breaking restriction of 'low bulk and low-speed production of nano-spun fibers' and integrating film industry with textile industry.

Method and apparatus for producing ultra-smooth knitted fabric using hairy yarn belong to a technical field of textile. Yarn is false-twisted in a rotary holding form, for rotating the yarn stem on an ironing face. Meanwhile, a directional hairiness stretching device directionally ejects a steam flow towards the yarn, for reversely and orderly pre-wrapping hairiness on the rotating stem of the yarn, which avoids the yarn imperfection occurrence as the hairiness randomly or vertically wrapping onto the yarn stem. A vortex hair-wrapping device is used, so as to reversely wrap all the rest hairiness on the stem of the yarn, wherein a wrapping direction is opposite to a yarn moving direction for increasing difficulty of pulling out the wrapped hairiness during weft knitting, and increasing hair-wrapping tightness and fastness. The ultra-smooth yarn treatment apparatus is reasonably constructed and easily operated, which facilitates wide application.

Disclosed are alicyclic[c]benzopyrone derivatives and use thereof. The alicyclic[c]benzopyrone derivatives are compounds represented by formula I or their salts. The present compounds not only significantly improve high activity induced by MK-801, but also effectively improve clambering symptom induced by Apomorphine and do not cause EPS within effective dose. These in vitro targets and in vivo pharmacological models are closely related to diseases of the nervous system caused by dopamine dysfunction, especially schizophrenia. Therefore the present compounds can be used for the treatment of central nervous system diseases, especially schizophrenia. EDis lower and effect is stronger in two animal models i.e. high activity induced by MK-801 and clambering symptom induced by Apomorphine, while EDis higher and therapeutic index is greater in animal models of catalepsy.
