The invention discloses an inner and outer dustproof oil seal structure. The inner and outer dustproof oil seal structure is of an annular integrated structure, and comprises an outer framework, an inner framework, a main lip, a spring, an external auxiliary lip and an internal auxiliary lip; the internal auxiliary lip comprises a body and a first protruding portion; and the first protruding portion is obliquely raised on the body and faces the oil side. The main lip plays an oil sealing role, the external auxiliary lip plays a role in isolating external foreign matters, and the internal auxiliary lip plays a role in isolating internal foreign matters. Therefore, the problem of damage caused by contact of the main lip and impurities in the box body in the prior art is solved, and double dust prevention is realized on the oil seal structure. Meanwhile, the existing structure of the box body is kept unchanged to the maximum extent, the installation process is not changed, and the cost issaved. Furthermore, the inner and outer dustproof oil seal structure adopts a generalized design and is wide in application range.

The invention relates to an aluminum-wood composite profile, which comprises an aluminum substrate and a wooden substrate. The aluminum substrate is provided with a groove for accommodating the wooden substrate. The groove is surrounded by a bottom plate, a first side plate and a second side plate. In this way, the first side plate is provided with a first bend that bends inward, and the inner side of the second side plate is provided with a first protrusion and a second protrusion, and the first protrusion is located between the second side plate and the bottom plate. One end of the connection; the second protrusion is located in the groove, and there is a distance from the first protrusion; the length of the second protrusion is smaller than the length of the first protrusion; a gap is provided on the outside of the second side plate; the wooden base material One side is provided with a protruding outward protruding corner that cooperates with the bending, and the other side is provided with a first concave surface and a second concave surface that cooperate with the first protrusion and the second protrusion. When installing the aluminum-wood composite profile provided by the present invention, it is only necessary to open the first side plate, fill the wooden base material into the groove and press the second side plate. The actual operation is simple, time-saving and labor-saving.

The invention discloses a host identity legality detection method, a detection device and an identity detection device, wherein the host identity legality detection method includes the following steps: acquiring the time offset of several moments of the host to be detected; The corresponding time offset obtains the time offset rate of the host to be detected; the identity legitimacy of the host to be detected is detected according to the time offset rate. Because the clock oscillation frequency of different hosts is different, each host on the network has a unique and fixed clock skew rate, and the clock skew rate of the host has nothing to do with the host's location, IP address, network topology and measurement time , has a certain stability. Therefore, detecting the legality of the host's identity through the clock skew rate of the host can solve the problem in the prior art that the reliability of identifying the legality of the host's identity with the IP address or MAC address is relatively low. low problem.

The invention discloses an internal field intensity balancing method for medium-voltage mutual inductor. The method comprises the following steps: performing region partition according to a field intensity distribution situation between a primary winding and a secondary winding obtained through structural analysis of the mutual inductor; winding the outermost layer of the primary winding with semiconductor crinkled paper of different surface resistance values, wherein the semiconductor crinkled paper of lower surface resistance values is wound in regions with higher field intensities between the primary winding and secondary winding, and the semiconductor crinkled paper of larger surface resistance values is wound in regions with lower field intensities between the primary winding and secondary winding; and assembling the primary winding and the secondary winding, and filling the space between the primary winding and the secondary winding with a main insulator. Through adoption of the method, the field intensities between the primary winding and the secondary winding can be balanced; the partial discharge amount is reduced; the original structures of the primary winding and the secondary winding are kept constant; and the parameters of the medium-voltage mutual inductor are not reduced.

The invention discloses a HEMT-based annular opening terahertz amplitude modulator and a manufacturing method thereof. Electrodes; the modulation array is composed of M×N modulation array elements arranged periodically, the modulation array element is composed of 4 open circular structural units, and the opening of the structural unit is matched with a high electron mobility transistor, the high electron mobility transistor The gate of the gate is connected to the Schottky electrode through the gate feeder and then connected to the negative electrode of the power supply. The source and drain of the high electron mobility transistor are respectively connected to both sides of the opening of the structural unit, and the structural unit is connected to the ohmic electrode through the source-drain feeder. Positive power supply. The supersurface resonant mode is converted by controlling the high electron mobility transistor with an external bias voltage, and the fast amplitude modulation of the terahertz wave propagating in free space is realized, and the different modes of the structural unit are mutually converted to achieve the modulation of multiple frequency points.

The invention relates to a method for quickly eliminating waste materials and remaining iron in a furnace during blast furnace overhaul. The method is a quickly eliminating method for mechanically detaching waste materials and carbon bricks in a furnace on the premise that a blast furnace shell is locally changed, particularly for mechanically detaching and cleaning furnace materials and carbon brick refractory materials on the premise that the blast furnace shell is locally changed, and moreover synchronously knocking and crushing remaining iron clots in the furnace by means of detaching and falling of the upper cooling wall, and removing both remaining iron clots and waste materials out of the furnace by virtue of a grab excavator. The method has the characteristics of use of few labors, high detaching speed, convenience in operation, quick construction, safe construction and the like, and can be used for increasing the speed for cleaning waste materials in the furnace in the process of blast furnace overhaul. Compared with traditional manual detaching and cleaning mode, the method has the advantages that the speed for cleaning waste materials and remaining iron in the furnace during blast furnace overhaul can be increased and the safety factor of the process of constructing in the blast furnace can be improved.
