Abstract: A device and a method for nondestructively detecting a transient characteristic of a conductive screw of a turbo-generator rotor are provided. The device includes a personal computer (PC), an extremely-steep pulse generator, an ultra-high-frequency double-isolation transformer, and a pulse emitting and coupling module, which are connected in sequence. The pulse emitting and coupling module is connected to a load. A synchronous pulse receiving non-inductive divider circuit synchronously receives a characteristic waveform from the load, and the synchronous pulse receiving non-inductive divider circuit is connected to an ultra-high-speed analog/digital (A/D) module through a nonlinear saturation amplifying circuit that amplifies a signal. The PC receives a signal from the ultra-high-speed A/D module. The load includes a positive or negative excitation lead loop that is in a 180° symmetrical and instantaneous short-circuit state and a rotor shaft.

Abstract: The present disclosure relates to a method for preparing liquid maltitol and liquid polyols from a raffinate including maltitol. The method comprises the following steps: obtaining a hydrogenated liquid by hydrogenating a pre-treated raffinate including maltitol, obtaining a post-treated liquid by post-treatment of the hydrogenated liquid to remove impurities, obtaining a dilute liquid and a concentrated maltitol solution by membrane-separation of the post-treated liquid, and using the dilute liquid as the liquid polyols, and obtaining the liquid maltitol by mixing the concentrated maltitol solution with a prepared maltitol solution with a maltitol content of over 50%, wherein the liquid maltitol has a maltitol content greater than or equal to 50% and meets a standard. Before the membrane separation process, the present disclosure reduces the reducing sugar content in the liquid by hydrogenation to lower the risk of yellowing during the process and to improve the quality of the final product.
