The invention discloses a high pressure deflection experimental method which can lead the sample grain refined. It comprises the following steps: 1) fixing cylinder-type up-and-down peg bars on the up-and-down rams of the presser, wherein one of the up-and-down peg bars can rotate and the end part of the rams is after fur handle; 2) cover-fixing a flank ring on the up-and-down peg bars with zero gap matching; 3) depositing the sample inside the flank ring and between the up-and-down peg bars, wherein the sample and the flank ring have the same internal diameter; 4) pressing 1-9GPa vertical pressure to the sample by presser and then keeping it and rotating the ram 0.1-10 loops.

A structure of an external wall or a roof and an external material for the external wall or a roofing material. In the structure of the external wall or the roof of a building, heat insulating and heat shielding performances are provided to a permeable layer for which dehumidifying action by the circulation of air was expected to secure high heat insulating and heat shielding performances for theexternal wall or the roof without changing the thickness of an insulator. Accordingly, when the heat insulating and heat shielding performances must not be changed, the thickness of the insulator canbe reduced less than before. The building in which an external material (11) is installed through the permeable layer (9) installed on the outside of the structure of the external wall or the roof ischaracterized in that low heat radiating sheets (8, 8a) having a low radiating performance against the heat radiation of long wavelength components are installed on the permeable layer (9) side surfaces of one or both of the external material (11) and the insulator (7).

The invention discloses a three-dimensional vane shape modification design method of a hydraulic torque converter based on conformal transformation, which solves the problems of low precision and serious distortion of three-dimensional vane modification of the traditional conformal transformation method, and belongs to the transmission technology of construction machinery. field.
