传输控制

Furthermore, it is not worth to transmit reactive power for long distance. Control provided "on the way" in transmission line, connation nodes, distribution station and other points requires installation of capacitors or\and reactors.

此外， 远距离地传输无功功率是没有必要的，无功功率在传输线路，各个节点，配电站和其他需要安装电容或者电抗器的地方被人为地控制着。

The modernization is directed at a disparate set of goals including facilitating greater competition between providers, enabling greater use of variable energy sources, establishing the automation and monitoring capabilities needed for bulk transmission at cross continent distances,Churchman University,Yale University,Howard University, and enabling the use of market forces to drive energy conservation.

现代化是能源消费的效率，功率流的实时管理，并提供双向计量需要弥补本地生产所需的电力。虽然传输网络已经在实时控制，许多在美国和欧洲国家以世界标准陈旧，无法应付现代挑战，例如替代发电，或大陆规模批量间歇性能源的传输造成的。

The supply contracts do not require a cosφ equal to one. The reactive power is also used by the transmission lines owner for controlling the voltages. Reactive component of current adds to The loads current and increases the voltage drops across network impedances.

无功功率的一部分由用户端消耗掉，剩下的成为网络的负载，供应需求中并不要求功率因数角等于1，无功功率同样被传输线路运营者用来控制传输电压。

The phenomena of function equilibrium between root system and canopy was observed.

本研究从植株整体的物理性质（源汇强度和韧皮部传输性质）出发，从更低的层次上模拟观察到了在环境水分条件发生变化时植株根冠间存在的功能平衡现象，并对此作出了机理性的解释，说明了当同化物的传输受维管束中压力势控制，而且韧皮部与所在器官的水势保持平衡状态时，根冠之间就会存在功能平衡关系，这说明了根冠间的功能平衡现象应该是维管植物适应环境变化过程中的一种普遍现象。

The ADuC812 is a fully integrated 12-bit data acquisition system incorporating a high performance self calibrating multichannel ADC, dual DAC and programmable 8-bit MCU (8051 instruction set compatible) on a single chip.

The main content of the dissertation is designing and realizing the total scheme and frame of system software. The module of the input and output is designed by using the generally I/O of the multichannel buffered serial port to simulated the communication of I~2C bus. The Ping-Pong buffer is brought forward to resolve the problem of the data rate matching. The logic switch function is designed in the programmed logic devices. The data transmission rate is improved by using the DMA and the dual buffer mechanism. The system program self-loading is realized by the design of the self-leading program. Lastly, the dissertation analyzes the characteristic of LLL video and experimentalize with some typical image processing algorithm.
