The results showed that all these factors except for light time obviously influenced the fly growth and fecundity. 结果表明:除光照时间(LT)外,其他因子对果蝇的生长、繁殖都有明显的影响。
The seasonal and daily changing laws of light time, solar radiation, transmission rate of solar radiation and the space distributing laws of solar radiation inside solar greenhouse were studied. 对日光温室内的光照时间(LT)、太阳总辐射量、太阳辐射透过率的季节变化和日变化,光照度的空间分布规律进行了较为系统的研究;
Effects on Callus Induction and Differentiation of Different Light Time(LT), Temperature and Type of Carbohydrate Source from Ramie 光温条件及碳源对苎麻愈伤生长和分化的影响
Light plays very important role in the growth of Gametophyte clone. Light time and intensity affect its growth directly. 光照对海带配子体克隆的生长起着至关重要的作用,光照时间(LT)和光照强度直接影响着克隆细胞的生长。
Firstly optimizing function is made to minimize the total delay, then non-linear programming model with restrictions of saturation and minimum green light time is constructed, and then genetic algorithms is applied to solve this model and the best scheme of signal timing can be obtained. 首先以总延误时间最少为目标建立优化函数,然后以饱和度限制及最小绿灯时间要求为约束建立非线性规划模型,再采用遗传算法对模型进行求解以得到最优配时方案。
