The invention relates to a method for identifying pterocarpus macrocarpus species in a microdamage mode based on a fingerprint spectrum. The method includes the steps that micropore sampling is conducted with a drill bit, a sample to be detected is added into solvent to be subjected to ultrasonic extraction, the retention time D1 of characteristic peaks, a mass spectrum D2 and the peak area D3 of a total ions chromatogram of an extraction solution serve as qualitative parameters to form the GC-MS 3D fingerprint spectrum, and then authenticity of the pterocarpus macrocarpus species sample is judged by checking matching consistency or similarity between the characteristic peaks in the GC-MS 3D fingerprint spectrum of the sample to be detected and 3D data of characteristic peaks in a GC-MS 3D fingerprint spectrum of the standard pterocarpus macrocarpus species. The unique mass spectrum D2 of organic matter is used as one of important qualitative parameters, the qualitative parameters D1 and D3 are added to form the 3D fingerprint spectrum, and multi-layer fingerprint confirmation ensures that an identification method is conducted on the pterocarpus macrocarpus species to judge authenticity accurately. Authenticity of a pterocarpus macrocarpus species product is judged through the method, and results are accurate and reliable; microdamage sampling is conducted, and the sampling amount is small, so that repair is easy, and the appearance of the product is not damaged.

The invention discloses internal locking type furniture which comprises a furniture body with a drawer cavity and a drawer arranged in the drawer cavity in a drawable mode, the inner top wall of the drawer cavity is fixedly connected with an internal locking upper structure, the outer side wall of the drawer is fixedly connected with an internal locking lower structure, the drawer is detachably connected with a magnetic device, the inner locking upper structure comprises a bolt seat as well as a first bolt and a first reset spring which are arranged in the bolt seat, and the first bolt extends out of the bolt seat under the acting force of the first reset spring; the inner lock lower structure comprises a bolt plate provided with a first bolt hole; when the drawer is closed, the first bolt is inserted into the first bolt hole to lock the drawer; and the magnetic device attracts the first bolt outside the drawer to overcome the acting force of the first reset spring to move upwards to be separated from the first bolt hole so as to unlock the drawer. The lock structure is installed in the furniture drawer, and a lock-free drawer can be provided with a self-locking structure under the condition that the appearance of the drawer is not damaged.

The present invention discloses a system and method for generating and verifying a digital copyright seal. The copyright information is coded and encrypted into a segment code, and the copyright of creation is declared around a traditional seal text and a seal frame through a specific path. Accordingly, the digital copyright seal of the present invention provides high-resolution line codes for use as portable identification.

The invention relates to a fixing device for gripping apparatus on file binder, which is installed on rigid covering of file binder, the invention also relates to file binder setting gripping apparatus through fixing device. Said fixing device comprises: long slad part, and inserting part extending from back of long slad and inserting through pore of file binder. And the frame with four lines on front surface of encompassing plate is formed. The internal side of frame is used as surface plate, which recesses from frame surface towards inserting part. The place between surface plate and frame inside is equipped with cutting slot extending inside along plate. The invention provides a fixing device and index device for file binder, which can mount gripping apparatus through simple construction on file binder cover and set gripping apparatus and crestal index without damaging file binder appearance.

The invention relates to a method for identifying the dalbergia bariensis species in a microdamage mode based on a fingerprint spectrum. The method includes the steps that micropore sampling is conducted with a drill bit, a sample to be detected is added into solvent to be subjected to ultrasonic extraction, the retention time D1 of characteristic peaks, a mass spectrum D2 and the peak area D3 of a total ions chromatogram of an extraction solution serve as qualitative parameters to form the GC-MS 3D fingerprint spectrum, and then authenticity of the dalbergia bariensis species sample is judged by checking matching consistency or similarity between the characteristic peaks in the GC-MS 3D fingerprint spectrum of the sample to be detected and 3D data of characteristic peaks in a GC-MS 3D fingerprint spectrum of the standard dalbergia bariensis species. The unique mass spectrum D2 of organic matter is used as one of important qualitative parameters, the qualitative parameters D1 and D3 are added to form the 3D fingerprint spectrum, and multi-layer fingerprint confirmation ensures that an identification method is conducted on the dalbergia bariensis species to judge authenticity accurately. Authenticity of a dalbergia bariensis species product is judged through the method, and results are accurate and reliable; microdamage sampling is conducted, and the sampling amount is small, so that repair is easy, and the appearance of the product is not damaged.
