摘要:
The present disclosure is related to a device for controlling thermal convection velocity of a biochemical reaction. The thermal convection velocity controlling device includes a base body for disposing a tube which is movable, wherein the tube is filled with a buffer of the biochemical reaction; a heating source located at a bottom of the tube or at a side of the tube to heat the buffer; and a flow rate adjusting apparatus for controlling a thermal convection flow direction of the buffer in the tube, whereby the flow rate adjusting apparatus changes a flow velocity and a flow time of the buffer. The present disclosure is also related to a method for controlling thermal convection velocity of a biochemical reaction using the device.

A capillary for apparatus of insulated isothermal polymerase chain reaction is mounted onto a test tube holder. The capillary includes a tube which has an elongated tubular housing space that is cut to form an axial cross section with a distance between left and right edges greater than the distance between front and rear edges. When reactants are filled in the elongated tubular housing space and heated to generate convection, the left and right edges of the axial cross section form a narrower passage to reduce flowing speed of heat flow in the convection and increase cycling duration of the convection. Hence reaction duration of the reactants is prolonged, and reaction efficiency of the apparatus of insulated isothermal polymerase chain reaction also is increased.

A non-contacting aligning method for planes in a three-dimensional environment is disclosed. The method includes: projecting a light beam in a predetermined incident angle onto a transparent first object and an opaque second object that are facing each other; and calculating a distance between the first and second objects basing on the tangent trigonometric function of the incident angle of the light beam.
