The present invention provides an ion analysis device, comprising: a first ion source for providing analyte ions; a second ion source for providing auxiliary ions; the positive and negative polarities of the auxiliary ions are opposite to those of the analyte ions, the ion cloud of the auxiliary ions overlaps with the ion cloud of the analyte ions in spatial distribution, and at least part of the analyte ions do not produce a chemical reaction with the auxiliary ions; an ion analyzer for analyzing the analyte ions; an ion transmission device, located between the first ion source and the ion analyzer, for transmitting the analyte ions into the ion analyzer and refusing the auxiliary ions from entering the ion analyzer. The present invention can reduce or eliminate the space charge effect between a large number of analyte ions, thereby improving the ion analysis performance under such conditions, such as sensitivity, resolution, etc.

This application relates to a double-layer straight-line tool magazine and a precision engraving machine. The double-layer straight-line tool magazine includes a tool magazine body, a first drive mechanism, and a second drive mechanism. It includes an upper tool disc and a lower tool disc stacked vertically. Both the upper and lower tool discs have multiple rows of tool positions arranged in a second direction along a first direction, and the tool positions are used to load tool holders. The first drive mechanism is driven by the tool magazine body, driving the tool magazine body to move along the first direction. The second drive mechanism is driven by the lower tool disc, driving the lower tool disc to move along the first direction. The upper tool disc and the lower tool disc form a double-layer tool disc structure stacked vertically. Both the upper and lower tool discs have multiple rows of tool positions arranged in the second direction along the first direction, shortening the spacing between the tool positions and increasing the spatial density of the tool positions. Through the above configuration, the drive of the upper and lower tool discs can be independently controlled, increasing the tool magazine capacity and adapting to the needs of multiple tool changes for complex parts.

The application discloses a device for detecting nano-particles by using ultrasonic condensation method, which is characterized by comprising a laser light source (1), a circular tube-shaped ultrasonic transducer (2), a fan (3), a driving circuit (4), an optical lens (5), a photodiode (6) and a detection circuit (7). The device drives nano-particles to condense at a standing wave node position by using an ultrasonic standing wave field, so that the spatial density of the nano-particles is greatly improved, the scattering of the nano-particles to a laser beam is increased, and the detection sensitivity of the nano-particles is remarkably improved.
