Microstrip switch type phase shifter and phase shifting module using same

The invention provides a microstrip switch type phase shifter and a phase shifting module using the same. The microstrip switch type phase shifter comprises a reference branch circuit, a phase shifting branch circuit, a first path selection switch and a second path selection switch, wherein the reference branch circuit comprises a first microstrip transmission line; the phase shifting branch circuit comprises a second microstrip transmission line and a third microstrip transmission line which are connected in series, and a fourth microstrip transmission line connected between a node between the second and third microstrip transmission lines and the ground level; the front end of the first path selection switch is connected to a signal input end, the rear end of the second path selection switch is connected to a signal output end, and the first and second path selection switches are simultaneously connected to the reference branch circuit and the phase shifting branch circuit under control. By adopting continuous microstrip lines and a simple topological structure, the phase shifter and the phase shifting module reduce parasitical parameters caused by discontinuous microstrip lines, can be applied to high-frequency scenarios, meanwhile, have very flat phase shifting characteristic nearby center frequency by simulation and experimental proof, and have high phase shifting precision.

Application of metabonomic technology in intrauterine growth retardation

The invention relates to application of metabonomic technology in intrauterine growth retardation, which is mainly characterized by starting from the view of system biology (Cowley AW Jr.The elusive field of systems biology. Physiol Genomics.2004;16(3):285-286), and applying a magnetic resonance spectroscopy technology based metabonomic method to seek a nuclear magnetic resonance spectrogram capable of specifically reflecting the intrauterine growth retardation in the peripheral blood of an experimental pregnant animal or a pregnant woman so as to provide proofs for further diagnosing the intrauterine growth retardation. The application comprises the following steps: during analysis, detecting a biological sample (comprising parent blood, embryo blood and amniotic fluid) of the pregnant animal or the pregnant woman in normal pregnancy and intrauterine growth retardation experiment by using nuclear magnetic resonance technology, acquiring a metabonomic spectrogram, analyzing the metabonomic spectrogram by using a pattern identification method, determining the metabonomic change of the intrauterine growth retardation through analysis and comparison, and acquiring one or more (groups of) nuclear magnetic resonance spectrograms for reflecting the intrauterine growth retardation from the metabonomic change so as to provide theoretical and experimental proofs for the subsequent further determination of a biomarker and the application of the metabonomic technology in the intrauterine growth retardation. The application has the advantages of high sensitivity, good specificity, early stage, non-invasion or micro-invasion and the like.

Preparing method for gray ultraviolet resistant non-woven

Provided is a preparing method for gray ultraviolet resistant non-woven. The preparing method comprises the steps of adding a polyester chip into a main stock bin, conducting crystalization and drying at the temperature of 165-175 DEG C, and then conducting fusion in a screw; adding black master batch and ultraviolet resistant master batch into a small stock bin, wherein the adding proportion of the black master batch accounts for 0.5-2% of the dosage of the polyester chip and the adding proportion of the ultraviolet resistant non-woven accounts for 1.5-3% of the dosage of the polyester chip, conducting drying on the mixture for 3-5 hours at the temperature of 85-95 DEG C, adding a big screw into the mixture, and conducting melt mixing on the mixture; conducting screw extrusion after mixing the polyester chip, the black master batch and the ultraviolet resistant master batch, and conducting spinning, cooling, traction tube drafting and web forming to obtain a 80-150 g / m<2> product; conducting acupuncture reinforcing to reinforce and control the thickness of the product. The gray ultraviolet resistant non-woven product has an excellent ultraviolet resistant effect and is mainly used for being paved on the lawn to achieve an effect of partial heat retaining. According to experimental proof, after being exposed under an ultraviolet radiator for 500 hours, the gray ultraviolet resistant non-woven still has a mightiness retention rate of 79%.

ActiveCN103341233ABiomagnetic field enhancementImproved biomagnetic fieldElectrotherapyMagnetotherapyExperimental proofEngineering
The invention particularly relates to an electromagnetic thermal therapy suit and a power source knapsack matched with the electromagnetic thermal therapy suit and belongs to the field of electromagnetic thermal therapy instruments. The electromagnetic thermal therapy suit comprises a clothing body and is characterized in that a therapy interlayer is arranged in the clothing body, and 2n magnetic stripes are fixed in the therapy interlayer and arranged in pairs in a mutually parallel mode. Coils are wound on the magnetic stripes. The winding directions of the coils on the adjacent magnetic stripes are opposite. All the coils are connected with inverters together through wires in series, and power interfaces are arranged in the inverters. According to the electromagnetism theory and experimental proof, when the electromagnetic thermal therapy suit is close to the human body, a coupling circuit is formed. After the coupling circuit is formed, electric currents in the thermal therapy suit are induced to the biological circuit of the human body, so that the purposes that the human body currents are adjusted and intensified, and the biological magnetic field is improved are achieved. The thermal therapy suit also can enable the human body to continuously generate a sense of warmth and a temperature needed for maintaining physical health and is particularly suitable for being used by an outdoor worker in winter, a mountaineering enthusiast, a surfer and other activity persons in the low-temperature environment.
