影响土壤比重的因素: 土壤比重仅仅取决于土壤固相颗粒的物质组成。 Since a large portion of most soils is composed of particles derived from quartz minerals, the particle density of most soils is near 2.6 g/cc which is the density of quartz. Variations in the particle density are due to the presence of heavier minerals like iron oxides or lighter organic components

Computer networks are geographically distributed collections of communication links and switching proces￾sors, the purpose of which is to transport data between computers, workstations, and terminals. In general the elements of a computer network must follow compatible rules of operation together to function effectively. These rules of operation are known as protocols

The true language of computers is a stream of 1s and 0s—bits. Everything in the computer, be it numbers or text or program, spreadsheet or database or 3-D rendering, is nothing but an array of bits. The meaning of the bits is in the “eye of the beholder”; it is determined entirely by context. Bits are not a useful medium for human consumption. Instead, we insist that what we read be formatted spatially and presented

1. Historical background: (1) The Hundred Years War: The result of the war was an awakening of national consciousness in England. And the French language was gradually replaced by English native tongue. (2) The peasant uprising of 1381: It was the result of the conflict between the peasants and feudal lords

Wet milling of cereal grains differs fundament￾ally from dry milling in being a maceration process in which physical and chemical changes occur in the nature of the basic constituents - starch, protein and cell wall material - in order to bring about a complete dissociation of the endosperm cell contents with the release of the starch granules from the protein network
