The invention discloses a goods shelf with a function of picking articles in a classified manner. The goods shelf comprises a framework, article display plates, an article picking device and a travelmechanism. The article display plates, the article picking device and the travel mechanism are fixed onto the framework, the particle picking device is mounted on the travel mechanism, a plurality ofstrip-shaped grooves are obliquely formed in the article display plates, and blocking edges which are used as barriers at the lower ends of the strip-shaped grooves are arranged at the lower ends of the strip-shaped grooves; the travel mechanism is used for driving the article picking device to change the locations in spaces, so that article picking mechanisms can move under the effect of the travel mechanism to reach the lower ends of the various strip-shaped grooves, and the articles at the lower ends of the corresponding strip-shaped grooves can be picked. The goods shelf has the advantagesthat the goods shelf is simple in structure, and the articles can be picked by the aid of the goods shelf in the classified manner.

The invention discloses a method for planting ramie on rice field ridges to increase natural enemies of insect pests in a rice field. Ramie is planted on the ridges around the rice field, varieties of the ramie are Xiangzhu 3# and Zhongzhu 1#, ramie stocks of ramie of second instar and older are planted at plant intervals of 35 to 50cm, the ramie is planted within 10 to 30 days after the transplantation of rice, and the rice field is managed according to the normal level. Two-year field tests show that by the ramie ridges, the species and the individual number of arthropods are increased by 20 percent and 17 percent respectively, the individual number of the natural enemies of the insect pests, such as spiders and parasitic wasps, are increased by 14 percent and 31 percent respectively, and great effects on the storage and the development of the species of the natural enemies of the insect pests in the rice field are achieved.

The invention discloses a short fiber rotor composite yarn spinning method. According to a traditional composite yarn manufacturing method, filaments and short fibers are combined and twisted into composite yarns, the short fibers are not completely used in the traditional composite yarn manufacturing method, and twined fibers are inevitably produced. The short fiber rotor composite yarn spinning method comprises the following specific methods that doffing yarns on a winding drum are thrown into a rotor; two kinds of fibers are fed into a combing roller through a feeding roller via two feeding openings, the combing roller decomposes the fed fibers into filaments which enter the rotor through a fiber conveying tube, and under the centrifugal effect of the rotor, the filaments slide into a collecting groove along the side wall of the rotor to be collected as collected strips; an air extractor enables the inside of the rotor to generate negative pressure, the doffing yarns which are thrown through a doffing tube are in lap joint with the collected strips in the collecting groove, and the composite yarns are formed. The composite yarns are output through the doffing tube and a doffing roller and wind the winding drum through a winding roller. The short fiber rotor composite yarn spinning method can increase the kinds of the composite yarns which can be spun by a rotor spinning machine, the twined fibers can be prevented, and the strength of the yarns can be enhanced.

The invention relates to a beneficiation method for separating rare metal concentrate and quartz feldspar concentrate. Polymetallic ore is subjected to gravity separation by a shaking table, and gravity concentrate, secondary gravity concentrate, gravity middling and gravity tailings are obtained; the gravity concentrate is subjected to strong magnetic separation, strong magnetic concentrate and strong magnetic tailings are obtained, wherein the strong magnetic concentrate is rare polymetallic bulk concentrate containing uranium, niobium, beryllium, rare earth and titanium, and the strong magnetic tailings are zirconium concentrate; and gravity middling is subjected to strong magnetic separation, strong magnetic concentrate and strong magnetic tailings are obtained, wherein the strong magnetic tailings are the quartz feldspar concentrate. According to the method, the recovery rate of rare metal mineral of the polymetallic ore can be remarkably improved to 70% or above, in addition, quartz feldspar which originally serves as tailings is recovered in a concentrate product mode, the resource utilization rate is greatly increased, and the method is free of any beneficiation reagents and has the remarkable economic and environmental benefits.

The invention discloses a fluorescence ternary correlation spectroscopy system for analyzing the binding interaction between three kinds of molecules. The fluorescence ternary correlation spectroscopy system includes at least three excitation light sources outputting different wavelengths. The fluorescence signal is divided into multiple signals according to the fluorescence wavelength, detected by a single photon detector, the signal is transmitted to the signal acquisition card and the calculation card, and the real-time calculation of the ternary correlation function is performed to obtain the fluorescence ternary correlation spectrum curve. This system realizes the fluorescence The ternary correlation spectrum obtains the fluorescence ternary correlation spectrum curve through the real-time recording of the fluorescence fluctuation signals of three kinds of fluorescent molecules emitting different wavelengths in the detection micro-area and the analysis of the ternary correlation function. The amplitude of the analytical curve is related to the three kinds of fluorescent molecular complexes. The relationship between concentration and the analysis of the co-binding interaction between three different molecules will be realized, which will expand the research of fluorescence correlation spectroscopy in situ analysis in living cells.

The invention discloses a system for identifying a detected product. The detected product is tested by test equipment. The test equipment comprises a power supply module, a control computer, a signal conditioning card and an analog input card. The power supply module supplies power to the control computer, the detected product and the signal conditioning card. The signal conditioning card is connected with the control computer through the analog input card. The control computer tests the detected product through a relay output and isolation digital quantity input board card of a PCI bus and a test card. The test equipment uses a multi-channel DI acquisition module to test each product. The invention further discloses a method for identifying the detected product. According to the method, DI channels are reserved, the species quantity of the identified products are changed according to practical requirements of different periods. Hardware identification is changed to software and hardware synchronous identification, and the species quantity and the reliability of product model identification is substantially improved.
