Abstract: Block-modified polysiloxanes and compositions comprising the block-modified polysiloxanes are useful in the field of textile finishing. Emulsions comprising the compositions have a very small and narrowly distributed particle size which increases penetration, and provide good softening properties coupled with good hydrophilicity.

Abstract: An information interaction system and method for heterogeneous detection and recognition devices for a low-altitude unmanned aerial vehicle (UAV) are provided, where each edge data unit is connected to a uniquely corresponding low-altitude UAV detection and sensing device and an access and distribution unit. The access and distribution unit is connected to a storage service unit and at least one scheduling and calculation unit. Each scheduling and calculation unit is connected to a comprehensive calculation and display unit. The comprehensive calculation and display unit is connected to the storage service unit. The storage service unit sends historical data to the comprehensive calculation and display unit after being authorized. The method is applied to the information interaction system for heterogeneous detection and recognition devices for a low-altitude UAV. A problem of data collaborative application of different low-altitude UAV detection devices is resolved.

Abstract: The invention relates to the field of mass cultivation of microalgae and specifically relates to a horizontal submerged cover type carbon supplement device and carbon supplement method for cultivating microalgae in an open pond. The horizontal submerged cover type carbon supplement device for cultivating microalgae in an open pond, comprises: one or more than two covers and gas distributors, wherein the gas distributor is arranged at the bottom of the open pond and the cover is arranged above the gas distributor; the cover, in form of a cylinder with openings at both ends, is arranged along the flow direction of the culture solution, the two ends of the cover being a culture solution inlet and a culture solution outlet respectively; the gas distributor is kept away from the culture solution outlet of the cover by more than 40 cm.

Abstract: The invention relates to the field of microalgae culture and specifically relates to a trap-type carbon supplement device and carbon supplement method for cultivating microalgae in an open pond. The trap-type carbon supplement device for cultivating microalgae in an open pond, comprises a trap-type container, a partition plate and a gas distributor, wherein the gas distributor is positioned at the culture solution inlet of the trap-type carbon supplement device; the thickness of the trap-type carbon supplement device on the side of the culture solution inlet is 0.5-2 times of the depth of the culture solution in the open pond; the gap between the lower end of the partition plate and the bottom of the trap-type container is 0.5-2 times of the thickness of the trap-type carbon supplement device on the side of the culture solution inlet; the upper end of the partition plate is higher than the wall of the trap-type container; and the width of the partition plate is matched with the trap-type container.
