The invention provides a spreader for an all-electric melting hexagonal glass-fiber tank furnace. The spreader comprises a vertical feeding pipe, a distributing pipe, a horizontal feeding pipe, a circulating water pipe, a feeder, a gear case, a motor and a water drum; and utilizes the motor to drive a main screw rod and a horizontal screw rod as well as the whole mechanism to rotate, thus, the raw material can be fast and evenly spread in the tank furnace, and the level fluctuation in the tank cannot be caused, thereby avoiding caking, guaranteeing the quality of the fiber drawing and the stability of the production, and greatly reducing the intensity of manual labor, adopting the water drum and circulating water can effectively protect a bearing and gears, thereby enabling the bearing and the gears to be high temperature resistant and prolonging the service life.

The invention relates to a flowing chamber of a flow cytometry and particularly relates to a magnetic stirring type flow cytometry flowing chamber. The magnetic stirring type flow cytometry flowing chamber comprises a flowing chamber body, a sample feeding needle and a sheath liquid chamber, wherein the sample feeding needle penetrates through the flowing chamber body and the sheath liquid chamber; the sheath liquid chamber is located above the flowing chamber body and is connected with the flowing chamber body through a sheath liquid hole; the flowing chamber body is internally provided with a magnetic bead; an electromagnet is arranged between the flowing chamber body and the sheath liquid chamber; and a sheath liquid inlet is formed at the upper end of the sheath liquid chamber. The magnetic stirring type flow cytometry flowing chamber can be used for rapidly stabilizing a laminar flow and saving energy sources. The sheath liquid still has a centripetal force when the sheath liquid is sprayed out from a nozzle; and the sample feeding needle is located at the circle center and is located at the position of a typhoon eye, so that the sample feeding needle can fall off in a straight line, is not mixed with the sheath liquid and does not block the nozzle.

The invention discloses a device and method for electrochemical hydrogen permeation measurement in a high-temperature environment and belongs to the field of electrochemical hydrogen permeation measurement technologies. The device comprises a cathode chamber, an anode chamber, an external circulating constant-temperature oil bath device, a constant current meter, an electrochemical workstation anda data collection device, wherein an electrolytic solution is contained in the cathode chamber and the anode chamber, organic alcohol with a melting point lower than 80 DEG C and a boiling point greater than 150 DEG C is used as a matrix of the electrolytic solution, phosphoric acid and phosphate are dissolved in the matrix, and the organic alcohol can dissolve the phosphoric acid and the phosphate in an 80-150 DEG C working environment. The test method comprises the steps that a sample is fixed into a double-electrolytic cell, the electrolytic solution is added into the cathode chamber and the anode chamber, and the external circulating constant-temperature oil bath device is utilized to maintain an electrochemical hydrogen permeation test in the cathode chamber and the anode chamber inthe 80-150 DEG C high-temperature environment. Through the device and method, the problem that electrochemical hydrogen permeation is unavailable under the temperature of 80 DEG C or above is solved,the temperature range of the electrochemical hydrogen permeation test is expanded, and important scientific research value is obtained.
