Only users registered beforehand in a network are able to obtain access to the network while maintaining strict security. Living-body authentication information for living-body authentication of a user 1A and access authentication information required for access to a network determined for each user are stored on the memory region of an electronic circuit mounted on a disk (or on an external storage medium). When the disk is driven, living-body authentication information is acquired from the user by living-body authentication means 11E. The living-body authentication information is compared with the living-body authentication information stored in the electronic circuit (or the external storage medium). When both are the same, the access authentication information stored in the electronic circuit (or the external storage medium) is sent to the network. Based on the received access authentication information, the network decides whether the user is a regular user and, when the user is decided to be a regular user, allows the connection of the user terminal with a service community.

Biological certification information of a user A and access certification information for each user are stored in a memory in an electronic circuit that is installed on a disc. At the time of driving the disc, the user's biological certification information and the biological certification information stored in the electronic circuit are compared and access certification information is sent out to a network when both information agree to each other. At the network, connection of the user's terminal to a service community is permitted when the user is determined to be an authorized one based on the received access certification information. Determined in the service community are an on-duty concierge who takes care of the service request by the user's terminal and an administration concierge who monitors communication information between the user and the on-duty concierge. Then, the administration concierge keeps monitoring communication information between the terminals used by the user and the on-duty concierge for generating a warning or compulsively interrupting the communication when the monitoring information meets the predetermined condition.

The invention discloses a large drift diameter built-in high-pressure sampling valve, which comprises a valve body, and is characterized in that a sampling core pipe is arranged in the valve body; an opening and a chute are formed on an upper wall of the valve body; the opening is communicated with the chute; the large drift diameter built-in high-pressure sampling valve is provided with a sealing sliding plate; an outline of the sealing sliding plate is matched with the shape of the opening; a sealing edge of the sealing sliding plate is a curved surface; small shafts at two ends of the sealing sliding plate are arranged in the chute and can rotate in the chute; and a sealing valve seat is arranged in the valve body. A special hard sealing structure is utilized, the sea bottom in-situ airtight sample core sampling equipment has excellent sealing characteristics under the seawater of 3,000 meters, sealing operation can be performed in the process of sampling, pollution-free and leakage-free acquisition of the sample core is realized, and the required original state and information of the sample taken from the sea bottom is guaranteed during a lab test, so that a real testing result is acquired; and in addition, extra complicated design is avoided, and the large drift diameter built-in high-pressure sampling valve has the advantages that the power supply is not required, the action is stable and reliable, and the sealing effect is good.

The invention provides a monitoring method for state of elements of high voltage electric power equipment. The present monitoring method for the state of the elements of the high voltage electric power equipment does not has a standard, and the absence of the standard leads to problem of false assessment to the state, wherein the standard is used for describing signals which are useful for external interference separating. The method comprises the following steps: 1. determining multiple self frequencies of the high voltage electric power equipment to be detected; 2. measuring and recording spectrum frequency of electromagnetic radiation when the electromagnetic radiation spectrum of high frequency wave band near the high voltage electric power equipment is stable; 3. comparing values of the multiple self frequencies determined in the step 1 and the frequency of the electromagnetic radiation spectrum in the step 2, and establishing information subband of the spectrum; 4. determining a standard constant value according to the spectrum value obtained from the established information subband of the spectrum; and 5. determining whether the whole technical state of the high voltage electric power equipment and the technical state of individual parts have a defect according to the standard value in the step 4. The monitoring method provided in the invention is used for monitoring the state of the elements of the high voltage electric power equipment.
