Abstract: Provided is a humanized anti-tissue factor antibody, an antibody-drug conjugate prepared therefrom and use thereof. The humanized anti-tissue factor antibody has high affinity to tissue factor. Also provided is an antibody-drug conjugate, which is obtained by coupling the humanized anti-tissue factor antibody to a cytotoxic drug.

The method includes the following steps: (S.1), filling an adsorption composition into adsorbers; (S.2), vacuumizing the adsorbers to remove air from the adsorbers, and then introducing a high-purity boron trichloride gas; and (S.3), introducing a boron trichloride feed gas into the adsorbers, such that the boron trichloride feed gas is in contact with the adsorption composition, and collecting a gas flowing out of the adsorbers to obtain an electronic-grade boron trichloride gas. According to the present disclosure, coordination formed between hydrogen chloride impurities and boron trichloride can be eliminated effectively, thereby improving adsorption and purification effects of the boron trichloride.

Abstract: The present invention relates to a rebound composite electromagnetic energy dissipation device for reducing sloshing with a liquid-filled ball for a large liquefied natural gas (LNG) storage tank. When the liquid surface sloshes around, the gas spring is pulled by the steel strand to produce vertical displacement and provide a restoring force, and the vertical displacement of the gas spring drives the fan blades on the sleeves of the ball screws at the bottom to rotate in the damping fluid, consuming energy. The present invention uses hydraulic transmission instead of mechanical transmission of traditional piston motion, and the horizontal pistons produce horizontal displacement in the case of pressure unbalance, thus increasing the flexibility of horizontal piston motion; magnets are arranged in the horizontal slideways and the horizontal pistons to intensify the motion of the horizontal pistons and the relative motion between the horizontal pistons and the interior.
