The invention discloses a silicon microphone, including a casing, a circuit board, a first sound channel which includes a first sound hole provided on the circuit board, and a piece body fixed at the inner side of the circuit board and covering the first sound hole, wherein, a second sound hole is provided on the piece body, the first sound hole and the second sound hole are in mutual staggered arrangement, a sound middle passage is provided between the first sound hole and the second sound hole for communicating both of them, and the a silicon microphone chip is mounted on the piece body in a position corresponding to the second sound hole. This technology uses a piece body and a circuit board together to form a horizontal channel, to achieve the purpose of environmental protection, to avoid excessive application of the circuit board substrate layers, and to reduce manufacturing costs.

The invention belongs to the technical fields of soil repair and environmental friendliness and in particular relates to a combined microwave oxidation compound repair system and method aiming at organic arsenic pollution in soil. The repair system comprises a microwave thermal desorption system, a soil oxidation system and a waste gas treatment system. The method comprises the following steps: allowing the polluted soil to enter the microwave thermal desorption system, adding a catalyst, performing heating, microwave radiation and thermal desorption treatment, volatilizing most of pollutants in the soil into a gas state for emission, discharging the soil through a discharge opening in the microwave thermal desorption system and performing subsequent treatment; transferring a gas state matter into the bottom of oxidation equipment, and carrying out a strong oxidation reaction on an arsenic-containing organic matter to generate a stable arsenic-containing compound; further degrading the treated gas to reach the standard through an activated sludge tank, and discharging the treated gas into the atmosphere; and allowing the soil to enter an oxidation reaction pool, and feeding the soil into recovery equipment through an oxidation effect of oxidation liquid. According to the system and method, the soil subjected to organic arsenic pollution can be completely and effectively repaired, the soil can be recovered and repaired and is recycled, the waste gas is treated, and an environmental protection standard is reached.

The invention discloses a method and a device for realizing pseudowire protection switching. In the scenario of PW dual-homing plus linear protection, the head node of PW dual-homing is the edge router PE1, and the tail nodes of PW dual-homing are PE2 and PE3. The first label switching path LSP protection group of the primary PW is set between PE1 and PE2. A second LSP protection group of the standby PW is set between PE1 and PE3. The method includes: closing the TMC layer connection confirmation detection function of the transport multi-protocol label switching transport network service channel on PE1, PE2, and PE3; When the active path in an LSP protection group is unavailable, LSP protection switching between PE1 and PE2 is started; when the active and standby paths in the first LSP protection group of the active PW are unavailable, PW dual-homing protection switching is started , switch the PW dual-homing tail node from PE2 to PE3.

The invention discloses a processing method, apparatus, and system for TCP connection. The method comprises: a connection message that is sent by a client and is used for establishing TCP connection with a server side is received; a message type of the received connection message is determined, wherein the message types of connection messages at least include a synchronization message and a response message; when the message type of the connection message is the response message type, the response message is verified by using connection verification information, wherein the connection verification information is generated based on a synchronization message; and when the response message verification is done successfully, the response message is forwarded to the server side. Therefore, technical problems that the protection performance is poor and the connection response is delayed because connection needs to be established again after the TCP connection message sent by the client is verified can be solved.

The invention can make multi client sides to share one protected software product by setting an encrypting lock at the host machine at service side and connecting the host machine at client side to service side having the encrypting lock. The key information of the protected software product is saved in the encrypting lock and keeps normal running of software by interaction with the encrypting lock. The access of client side is controlled by service side, and one encrypting lock can be independently shared by multi client sides. By using the invention, the amount of software protecting devices can be decreased.

This invention discloses one business protection method, which adopts one to one protection set between two points positive path and comprises the following steps: a, business flow end point judges positive path shortcoming according to connection test results, if there is, then executing local point protection switching to generate BDI message at business flow mouth point and to send BDI message to business flow end point; b, business flow end points receive BDI message and executing local point switching.

A packing container especially for containing at least one display panel is composed of a case body, an upper fixing part, a lower fixing part, and at least one buffer part arranged between case body and the display area of display panel for protecting it.
