Harbin, China

The Harbin Institute of Technology is a research university and a member of the C9 League in China consisting of three campuses, which nearly span the country from north to south: the Harbin campus in Heilongjiang Province, the Weihai campus in Shandong Province and the Shenzhen graduate school in Guangdong Province.HIT undertakes research and numerous projects covered by official secrets which may have a bearing on its international ranking, although it is widely recognized as one of the top universities in the country, especially when it comes to local science and engineering league tables. HIT is one of only ten universities in the world that have designed, built, and launched their own satellites . It made the largest contribution to the success of the Shenzhou series spacecraft and Kuaizhou series spacecraft. One minor planet is named after the Harbin Institute of Technology and nicknamed "Hagongda Star" by the International Astronomical Union for HIT's achievements in science and engineering.

Aircraft engine rotors traditionally have low coaxiality after assembly. This is solved by the methods and devices described herein, having advantages that the rotors have high coaxiality after assembly, reduced vibration, easy installation, high flexibility, and improved engine performance. A measurement method and device use an air flotation rotary shaft system determining a rotary reference. An induction synchronizer determines angular positioning of a turntable. Using a four probe measurement device, a radial error of a rotor radial assembly surface and an inclination error of an axial mounting surface are extracted and an influence weight value of the rotor on the coaxiality of assembled rotors is obtained. All rotors required for assembly are measured and an influence weight value of each on the coaxiality of the assembled rotors is obtained. Vector optimization is performed on the weight value of each rotor and an assembly angle of each rotor is obtained.

A method for measuring a dip angle of oppositely crossly placed paired quartered ring-quartered circle nested polar plates. An annular coplanar capacitance measuring head of a sensor unit consists of four quarter round metal plates and four quarter circular-ring-shaped metal plates, the eight metal plates are coplanar and concentric with one another, and a quarter round metal plate and a quarter circular-ring-shaped metal plate corresponding to the same sector angle form a capacitor. Two annular coplanar capacitance measuring heads are arranged on two round insulating substrates, the two round insulating substrates are used as two bottom surfaces of a cylindrical container, the cylindrical container is transversely arranged, and an insulating liquid equal to volume of the cylindrical container is injected into the cylindrical container in a sealing manner. Potential leads extract potentials of the sixteen metal plates and are connected to an input end of a capacitance measuring unit, and the capacitance measuring unit is connected to a dip measuring unit. When the cylindrical container tilts, the relative positions of the two annular coplanar capacitance measuring heads and the insulating liquid are changed, and a dip angle value can be calculated by measuring the change of a capacitance value. Also disclosed is a device for measuring a dip angle of oppositely crossly placed paired quartered ring-quartered circle nested polar plates.


An optical window based on an array of rings and sub-rings having a triangular and orthogonal mixed distribution is suited for electromagnetic shielding. The array has metal rings of the same diameter acting as basic rings closely arranged according to an equilateral triangular and two-dimensional orthogonal square mixed arrangement and is loaded on an optical window transparent substrate surface. Adjacent basic rings are connected externally tangentially. Metal sub-rings are arranged within each basic ring and connected thereto internally tangentially. Each basic ring and its sub-rings constitute a basic unit. At tangential connection locations of the rings, wires overlap or metal is provided to ensure reliable electrical connections between connected rings, thus all rings are conductive. The metal grid structure significantly reduces non-uniformity of grid high-order diffracted light intensity distribution, thereby causing stray light distribution caused by diffraction to be more uniform and imaging to be less affected.


Optical windows based on a multi-period master-slave nested ring array of concentric rings are suited for electromagnetic shielding. A metal grid of the ring array has basic rings, concentric sub-ring pairs, secondary sub-rings, filling rings, concentric modulation ring pairs, and modulation sub-rings. Basic rings and concentric modulation ring pairs form a two-dimensional orthogonal array. External rings of concentric modulation ring pairs are externally tangentially connected to basic rings. Concentric sub-ring pairs and filling rings are arranged within basic rings, secondary sub-rings are arranged within concentric sub-ring pairs, and modulation sub-rings are arranged within concentric modulation ring pairs. Where rings are tangentially connected, wires overlap or metal ensures reliable electrical connections between connected rings, thus all rings are conductive. The metal grid structure significantly reduces non-uniformity of grid high-order diffracted light intensity distribution, causing stray light distribution caused by diffraction to be more uniform and imaging to be less affected.
