以往在用人工光源进行海洋生物培养中,每日都须由人工启闭光源。启闭光源的工作量虽然不大,但每次要做到准时开关就非易事。目前虽有各种不同规格商品的计时器、延时器,但大都控制在12小时或1小时甚至更短的时间范围内,对在进行海洋生物培养的光照实验里(光、暗周期是24小时)都不适用。我们参阅了有关资料,制作了一台时间程序控制器 In the past in the use of artificial light for marine life training, the daily opening and closing of light by artificial sources. Although the workload of the light source is not large, but every time to be on time switch is not easy. Although a variety of different specifications of the timers, timers, but most of the control in 12 hours or 1 hour or less time range, in the light of marine culture experiments (light, dark cycle is 24 Hour) are not applicable. We refer to the information, produced a time program controller
