The invention discloses an annular PTC heater, and belongs to a heating device. An existing wind-heated bathroom heater can only blow wind to the specific direction or a local part, the comfort of people is affected, and the speed of changing from coldness to hotness of a bathroom is slow. The annular PTC heater is integrally made in an annular shape, and the annular PTC heater is provided with anairflow channel which extends in the axial direction, so that the annular PTC heater can blow wind by 360 degrees. The annular PTC heater is applied to a fan, and heating can be achieved. According to the annular PTC heater, the wind-heated bath heater can blow wind towards all the directions by 360 degrees to spread heated air to the bathroom, so that the heated air is evenly distributed, and the fact that heated air is unevenly distributed or local heated air is maintained is not caused; the speed of the bathroom from coldness to hotness is speeded up, the wind-heated bath heater warms people in the mode of wrapping human bodies from all the directions, the heated air cannot blow wind to the human bodies, and the comfort of people is improved.

A readout circuit for a bolometer type sensor including a pair of back-to-back temperature sensing diodes connected in an electro-thermal feedback loop including a semiconductor amplifier circuit located in an intermediate stage between a detector stage and a heat bath stage and wherein the heat generated by the amplifier equalizes the temperature between the intermediate stage and the detector stage. The readout circuitry also includes circuitry for removing local threshold voltage variations and low frequency 1 / f noise components in the readout signal while providing high temperature sensitivity and relatively high voltage gain.

The invention discloses a method for simultaneously and efficiently extracting soluble sugar and organic acid from peach pulp. The method comprises, a, preparing an extraction agent according to a ratio of ethanol to 0.4% metaphosphoric acid aqueous solution of 80: 20V / V (pH of 4.1), and b, weighing peach pulp, adding the extraction agent into the peach pulp according to a material-liquid ratio of 1: 16, carrying out ultrasonic-assisted extraction for 1h, carrying out centrifugation, taking a supernatant, carrying out condensation by a condensation device until drying, and dissolving the extract in ultrapure water to obtain the soluble sugar and organic acid solution. The method for simultaneously and efficiently extracting soluble sugar and organic acid from peach pulp utilizes the extraction agent comprising ethanol and 0.4% metaphosphoric acid aqueous solution according to a ratio of 80: 20V / V, is free of additional condition of ice bath or heat bath, and realizes efficient and comprehensive extraction of soluble sugar and organic acid from peach pulp at a normal temperature. The extraction agent can delay extraction solution cane sugar degradation, does not produce obvious degradation conversion in four weeks, does not influence later experiment result reliability, and greatly saves materials, time and a cost.
