Route recovery method according to failure positioning in automatic exchange optical network

The invention relates to a route recovery method in automatic switched optical network according to fault location. The method comprises: when a fault occurs to connection through detection, the failure point of the connection or two adjacent nodes of a link transmits fault location information to a connected initial node, and the fault location information comprises influenced nodes in the current used route of the connection, and the information of the link; the initial node determines the faulted link and node according to the received fault location information and determines the reusable link resource and the avertable resource on the original route, the faulted link and node can be avoided through the faultless links in the connection so that the connection can be recovered after the route is successfully queried. By applying the route recovery method, when failures occur to a plurality of links or nodes or the link resource is not sufficient, the fault point can be positioned accurately according to the fault information, and the method has the advantages that the amount of information transaction is small, the speed of information transfer is fast, the resource conflict can be reduced as far as possible, the connection recovery efficiency can be improved, the realization is simple, the equipment cost is saved and the flexibility is high.

Apparatus and method for controlling the voltage applied to an electrostatic shield used in a plasma generator

An apparatus for controlling the voltage applied to a shield interposed between an induction coil powered by a power supply via a matching network, and the plasma it generates, comprises a shield, a first feedback circuit, and a second feedback circuit. The power supply powers the shield. The first feedback circuit is connected to the induction coil for controlling the power supply. The second feedback circuit is connected to the shield for controlling the voltage of the shield. Both first and second feedback circuits operate at different frequency ranges. The first feedback circuit further comprises a first controller and a first sensor. The first sensor sends a first signal representing the power supplied to the inductive coil to the first controller. The first controller adjusts the power supply such that the power supplied to the inductor coil is controlled by a first set point. The second feedback circuit further comprises a second sensor, a second controller, and a variable impedance network. The shield is powered via a variable impedance network. The second sensor sends a second signal representative of the voltage of the shield to the second controller. The second controller adjusts the variable impedance network such that the voltage of the shield is controlled by a second set point.

Method for identifying smut resistance in sugarcane

InactiveCN101696446AObjective intrinsic resistance levelObjective resistance levelMicrobiological testing/measurementMicroorganism based processesHigh resistanceInfection rate
The invention provides a method for identifying smut resistance in sugarcane. The method comprises the following steps that: screening a set of standard contrast varieties through at least three tests, which comprises at least two high resistance varieties, two medium resistance varieties and two infected standard contrast varieties; carrying out an artificial impregnation grafting evaluation test on the standard contrast varieties and materials participating in test evaluation simultaneously; recording the number of seedling emergence after the sugarcane is emerged; calculating the number of total clumps and the number of infected clumps on each line in harvesting; remaining perennial roots, and recording the number of seedling emergence and calculating the number of total clumps and the number of infected clumps on each line, and evaluating the clump infection rate according to the number of the total clumps and the number of infected clumps to calculate the infection rate; and calculating and evaluating the clone for classification through a regression equation of infection standard percentage (X) and standard classification thereof (Y). The method can reflect the inherent resistance level of the sugarcane identification materials more objectively, and minimize the interaction of environment to ensure more accurate identification result.
