当您尝试将资料产生器指派给具有唯一条件约束的资料行时，可用产生器的清单只会显示可以产生唯一值的产生器。
When you try to assign a data generator to a column that has a unique constraint, the list of available generators displays only generators that can produce unique values.
芯片内部主要包括数字控制器，显示数据存取器，DC - DC电压转换器，参考电流产生器，电压预充电路产生器，64个行驱动电路和132个列驱动电路。
It consists of a digital controller, SRAM for display data memory, a DC-DC voltage converter, reference current generators, a pre-charge voltage generator, 64 common drivers, and 132 segment drivers.
用80C196单片机作为显示处理机构成一块基于AT总线的插卡，用以取代原平视显示器教学模拟器显控计算机和矢量产生器插件板，使系统结构简化、成本降低，并提高系统可靠性。
An 80C196 MCS based on AT Bus replaces the Display Computer and Vector Generator board of the old HUD Teaching Simulator. It reduces system form and costs, also improves system reliability.
