A report data real-time audit method and device are provided. The report data real-time audit method comprises the steps of report template definition, single report compilation audit, single report batch audit and combined report compilation audit. The report template definition specifically includes the following steps that: a management user defines a report format; a number selection formula, a calculation formula and an audit formula are set in the report format; and a report template is made to be shared by each subordinate user. The single report compilation audit includes the step that when the subordinate users compile single reports under the report template, report data are audited under a report input state. The single report batch audit specifically includes the following steps that: after the compilation of all the single reports of the subordinate users is accomplished, batch audit is performed on all single reports under a current report audit user; and after the audit is accomplished, the reports are reported. The combined report compilation audit specifically includes the following steps that: the management user performs batch audit on all the reports; the management user compiles combined reports after the batch audit is accomplished; and report data are audited under a report input state when the combined reports are compiled. According to the report data real-time audit method and device of the invention, the report data are audited when the reports are compiled, and therefore, timeliness, authenticity and accuracy of the reports can be ensured.

The invention discloses a ZigBee technology-based wireless full-duplex real-time voice transmission device and method. The device is characterized by comprising a device A and a device B, which are same and on an equal footing, wherein the device A, as well as the device B, adopts the structure that voice signals are converted into analog voltage signals through an electret microphone; voltage signals are converted into the voice signals through an electrodynamic loudspeaker; a voice processing circuit converts the analog voltage signals output by the electret microphone into digital signals which are then sent to an embedded microcontroller circuit, and, at the same time, also receives and converts the digital voice signals output by the embedded microcontroller circuit into the analog signals which are then sent to the electrodynamic loudspeaker; and the embedded microcontroller circuit receives the digital voice signals output by the voice processing circuit, so as to compress the signals in a 'ping-pang' manner and then send the compressed signals to a ZigBee RF circuit for RF transmission, and also receives the data output by the ZigBee RF circuit, so as to decompress the data and then send the decompressed data to the voice processing circuit in a in a 'ping-pang' manner. The method and the device provided by the invention have the advantages of simple structure, and lower consumption and cost.

The invention belongs to the technical field of nano composite material preparation, and particularly relates to preparation of a core-shell type magnetic multi-color fluorescent probe and a visible detection method. The preparation of the rare-earth doped core-shell type magnetic multi-color fluorescent probe comprises the following steps: (1) loading fluorescein to magnetic halloysite by using a hydrothermal method, wherein the magnetic halloysite can show green fluorescence under a three-purpose ultraviolet analyzer; (2) to prevent the fluorescein from leaking out from the magnetic halloysite, dropping ammonium hydroxide into a mixed liquid of APTES+TEOS, and performing a reaction to substance hydroxyl of the product by amino so as to form a layer of a protection membrane; (3) grafting an ethylenediamine tetraacetic acid derivative, performing coordination with rare-earth ions to form a chelate compound, thereby obtaining the fluorescent probe. The invention further relates to a visible detection method. Fluorescent testing on DPA of detected substances of different concentrations is carried out after the fluorescent probe is mixed with a Tris-HCl buffer solution, and multi-color fluorescent variations show the recognition performance of the fluorescent probe.

The invention discloses a well logging method capable of storing the relative flow rate. The well logging method comprises the following steps that the working time of an instrument and the releasing time of a tracer agent are set according to existing data of a to-be-logged well; an assembled flow instrument is descended into the well through an anti-spraying unit special for a steel wire; a standard curve is measured according to basic data of the well, after being released, the tracer agent is continuously traced according to the data of the well, and detected curve data are recorded through the flow instrument till the working time is over; the flow instrument is got back to the ground, the data recorded in the instrument are read, and then the data and depth data in a depth recorder are combined through the time, the trend of the depth is judged in the combining process, and a plurality of lifting curves and a plurality of lowering curves are obtained; and datum treatment is conducted, depth-correcting calculation is conducted firstly, and then the flow rate of the current depth can be calculated by calculating the lifting curves. According to the well logging method capable of storing the relative flow rate, overflow can be eliminated, so that the error brought by measuring is zero, and under the conditions of being low in injecting quantity and high in pressure, logging accuracy can be greatly improved.

An apparatus, system, and method are disclosed for aberration compensation. In one embodiment, a first compensation lens used in conjunction with a second compensation lens to produce a conical beam used to read from, or write to, an optical medium. An Nth order compensation equation is used to optimize aberration errors associated with accessing the optical medium. The present invention may include a displaceable focus lens positioned relative to an optical medium. The focus lens may be displaced when the conical beam's focal length is adjusted. A displacement equation is presented to determine the preferred placement of the focus lens. By compensating for aberration, read / write errors may be reduced while accessing optical media thus increasing system robustness and facilitating the use of additional layers on optical media.
