摘要:
A method for generating a transport stream of a server is provided. The method for generating a transport stream of a server which sends broadcasting content to a client device comprises: scrambling broadcasting content by using a specific key; adding at least one content-encryption message which includes the specific key and a device key for obtaining the specific key from the at least one content-encryption message to the broadcasting content so as to generate a transport stream; and sending the generated transport stream to the client device.

The present invention features a steel-base sintering alloy having a high wear-resistance for a valve seat of an engine. In preferred embodiments, the steel-base sintering alloy may include a chief element of Ferrum (Fe); and a powder-alloy which are composed of Carbon (C) of 0.6˜1.2 wt %, Nickel (Ni) of 1.0˜3.0 wt %, Cobalt (Co) of 15.0˜25.0 wt %, Chrome (Cr) of 3.0˜9.0 wt %, Molybdenum (Mo) of 8.0˜15.0 wt %, Tungsten (W) of 1.0˜4.0 wt %, Manganese (Mn) of 0.5˜2.0 wt %, and Calcium (Ca) of 0.1˜0.5 wt %.
摘要:
A method for quantifying plant resource using a GIS is disclosed, in which it is possible to more efficiently quantify plant resources with less manpower, time and cost using a GIS when quantifying plant resources in a certain region. In the method, a sample group is extracted from mother groups having a plurality of distribution maps having a plurality of environment factors including IMI as attribute data, the IMI being obtained through a GIS preprocess. A relative model formula is obtained between a plant resource real measurement value of the sample group and an environment factor real measurement value and is related with the distribution map of the mother group, and the distribution maps are overlapped for thereby forming a plant resource estimation distribution map of the mother group.
