摘要： Disclosed is a method and apparatus for measuring in-situ stress in rock using a thermal crack. The method involves forming a borehole, cooling a wall of the borehole, applying tensile thermal stress, forming a crack in the borehole wall, and measuring temperature and cracking point. Afterwards, the borehole wall is heated to close the formed crack, the borehole wall is cooled again to re-open the crack, and temperature is measured when the crack is re-opened. The in-situ stress of the rock is calculated using a first cracking temperature at which the crack is formed and a second cracking temperature at which the crack is re-opened. Further, the apparatus cools, heats and re-cools the borehole wall, thereby measuring the first cracking temperature, the second cracking temperature, and the cracking point.

摘要： A method of attaching a first member of one of quartz and a ceramic to a metal member. The method includes creating a hole in the metal member, the hole being smaller in size than the size of the first member over a temperature range, heating the metal member to a temperature sufficient to expand the hole to allow insertion of the first member in the hole, inserting a portion of the first member into the hole, and cooling the metal member to form a joined structure of the first member and the metal member.

摘要： A gravity gradiometer for measuring off-diagonal components of the gravitational gradient tensor includes a housing having a pair of electromagnetic shield enclosures (22, 23) arranged one inside the other, and a body (25) including superconducting material mounted within the inner enclosure (23) for fine pivotal flexure about an axis passing substantially through the centre of mass of the aforesaid body. An array of superconducting coils (30) is supported by the outer enclosure (22) and positioned in close proximity to the aforesaid body (25) for diamagnetically applying a rotational force to the body with respect to the axis of flexure and/or for responding by modulation of inductance to pivotal flexure of the body arising from a gravitational gradient across the body. The array is arranged to apply the rotational force in both rotational directions and to respond to flexure in either rotational direction. Also disclosed is a flexural pivot bearing which includes a pair of members (28, 31) with opposed close-spaced faces. These faces are joined by a web (29), of microscopic thickness, in a plane intersecting the faces. The members and the web are formed of an integral body of substantially uniform material, and the members are adapted for pivoted mutual flexure about a pivot axis aligned along said web.

摘要： An atomic gravimeter device includes one or more lasers and three or more atomic sources. The three or more atomic sources are disposed to launch or drop atoms vertically. The one or more lasers are disposed to generate laser beams that interact with sets of atoms from an atomic source of the three or more atomic sources to measure accelerations of the sets of atoms. A measured value is determined for gravity using interwoven acceleration measurements of the sets of atoms from the three or more atomic sources.

摘要： A time-delayed enlarged three-dimensional (3D) gravitational wave detection system may include a three optical fibers along three axes (X, Y, and Z-axis); and a laser signal source operatively linked with the three optical fibers; wherein structures of the three optical fibers are identical, and are adapted to pick up space/lengths changed caused by gravitational waves. And, the laser signal source includes a narrow linewidth laser to generate laser lights, an electro-optic modulator (EOM) connected with the narrow linewidth laser to modulate the phase of laser light, and a RF signal source connected to the EOM to provide ultra-stable RF signal to the EOM. In one embodiment, said narrow linewidth laser is adapted for carrying the ultra-stable RF signal, and said ultra-stable RF source is used for detecting length changes caused by the gravitational waves.

摘要： A motion detecting device includes an accelerometer configured to generate gravitational acceleration readings associated respectively with consecutive time segments, an angular acceleration sensor and configured to generate angular acceleration readings, and a processor operable in one of a standby mode and an active mode. When operated in the standby mode, the processor activates the accelerometer, deactivates the angular acceleration sensor, and determines whether the user is in a substantial moving state. When determined that the user is in the substantial moving state, the processor switches to the active mode to activate both the accelerometer and said angular acceleration sensor, in order to determine the motion of the user.

摘要： The general field of the invention is that of matter-wave gravimeters. The gravimeter according to the invention comprises at least: means for generating, for capturing and for cooling a cloud of ultra-cold atoms; means of transferring the atoms into a superposition, with equal weights, of a first internal electronic state called state |1>) and of a second internal electronic state called state |2> comprising the application of at least a first microwave field and of a radiofrequency field; means for separating the atoms into two wave packets for a given period of time under the effect of at least a second microwave field, the said separation leading to a phase-shift associated with the local gravitational field; calibration means allowing a “magic” magnetostatic field to be determined for which the difference in energy between the first internal electronic state and the second internal electronic state is independent, to a first order, of the fluctuations of the magnetostatic field.

摘要： An acceleration measuring device is disclosed, for use as a gravimeter or gradiometer for example. The device has a support and a proof mass, connected to each other by at flexures allowing displacement of the proof mass relative to the support. The support defines a space for displacement of the proof mass. The device is configured so that the modulus of the gradient of the force-displacement curve of the proof mass decreases with increasing displacement, for at least part of the force-displacement curve. This is the so-called anti-spring effect. The resonant frequency of oscillation of the proof mass is determined at least in part by the orientation of the device relative to the direction of the force due to gravity. The proof mass is capable of oscillating with a resonant frequency of 10 Hz or less. The proof mass has a mass of less than 1 gram.
