Abstract: The present invention relates to the field of flue gas nitrogen oxide emission, and in particular to a method and a combustion system for reducing nitrogen oxide emission. Introducing non-nitrogen inert gas as a combustion diluent to establish ignition; when the amount of circulation flue gas reaches a designed value, the introduction of the non-nitrogen inert gaseous diluent is stopped; and by means of circulation of a part of flue gas and a part of CO2 in the flue gas, the internal circulation of the whole process system is ensured. The present invention achieves the objectives of reducing the nitrogen oxide emission and saving the fuel, thereby saving the energy, protecting the environment, fundamentally solving the emission problem of NOx in the flue gas, and achieving carbon reduction.

Abstract: A process for producing olefins by steam cracking of a heavier hydrocarbon includes the steps of: subjecting a heavier hydrocarbon to a first separation to obtain a first vapour stream and a first liquid stream, partially condensing (second separation) the first vapour stream to obtain a condensate (third heavier fraction), introducing at least a portion of the third heavier fraction into the first liquid stream to obtain a first modified liquid stream, subjecting the first modified liquid stream to a third separation to obtain a second vapour stream and a second liquid stream, and carrying out steam cracking on the second vapour stream to obtain a cracked gas effluent containing the olefins. This process inhibits the coking of the convection zone, and provide a high utilization rate of heavier hydrocarbon (crude oil) and a high ethylene yield.

Abstract: An inner ring component for a physiological monitoring ring includes an inner ring, a circuit board, and a conduction component. The installation gap between the inner ring and the circuit board accommodates the circuit board having a light source and a light detection component. The light source emits detection light toward the user's finger, and the light detection component receives the reflected light formed by the reflection of the detection light from the user's finger. The conduction component, located in the installation gap, includes a filter and a first light guide that directs the reflected light to the light detection component. Compared to the prior art, the interference from external ambient light to the light detection component can be reduced, thus improving the accuracy of the light detection component's detection of the reflected light, and in turn improving the precision of the physiological information detected by the inner ring component.

Abstract: A bicyclic compound acting as a ROR? inhibitor. Provided are a compound of formula (I) or a pharmaceutically acceptable salt thereof, the compound having a structure as represented by formula (I-A) or formula (I-B). The provided compound of formula (I-A) or formula (I-B) or pharmaceutically acceptable salt thereof has good ROR? inhibitory activities, being expected to be used for treating diseases mediated by ROR? receptors in a mammal.
