The utility model relates to a sunshade system technical field, concretely relates to a V type pottery plate sunshade system. Include: the pallet is multiple, is fixed on curtain wall stand column, pottery plate is set between two adjacent pallets, pottery plate is V-shaped, and the opening is to the side away from curtain wall. In this application, the pallet can support and fix the pottery plate, the pottery plate is V-shaped, and the opening is to the side away from curtain wall, can increase the sunshade area of blocking direct sunlight into the room, and compared with rectangular pottery stick, also has the weight of relatively small, can make the pallet not damage.

The utility model relates to building curtain wall reconstruction technical field discloses a kind of exempt from disassembly sound insulation enhancement structure based on existing glass curtain wall, comprising: composite sound insulation wrapping layer, the composite sound insulation wrapping layer is attached to the original curtain wall column of existing glass curtain wall With the surface of original curtain wall beam, to be used for wrapping original beam column and blocking sound bridge transmission;Damping vibration isolation layer, the damping vibration isolation layer is arranged between composite sound insulation wrapping layer and original curtain wall column / original curtain wall beam, between special sound insulation glass and composite sound insulation wrapping layer, to be used for reducing vibration noise transmission.In the utility model, by the synergistic effect of "composite wrapping layer+special glass+damping vibration isolation+cavity", outdoor traffic noise is effectively reduced, the appearance and stability are maintained using existing curtain wall structure, the curtain wall K value can also be reduced, the adaptability is stronger and the service life is longer, and large equipment is not needed in construction.

The application provides a gold marker implantation position recommendation method and system, relates to the technical field of image-guided radiotherapy, and comprises the following steps: acquiring CT image data of a patient; determining a plurality of gold marker implantation points of a gold marker based on the CT image data; combining the gold marker implantation points according to a preset aggregation rule, and constructing a plurality of gold marker point sets; for each gold marker point set, respectively evaluating a three-dimensional geometric stability index and a two-dimensional observable stability index thereof; combining a preset evaluation rule and the geometric stability index and the observable stability index corresponding to each gold marker point set, and screening an optimal gold marker point set from all the gold marker point sets; and taking the gold marker implantation points in the optimal gold marker point set as recommended gold marker implantation positions. Through the quantitative evaluation of the geometric stability and the observable stability of the gold marker based on the CT image before implantation, the optimal implantation point is actively recommended, so that the distribution degeneration problem is eliminated, the rework after implantation is avoided, and the tracking accuracy and the treatment efficiency are ensured from the source.
