Feeding intensity and point-of-no-return (PNR) of Pelteobogrus fulvidraco larvae at different temperatures were studied under laboratory conditions.
对不同温度下黄颡鱼仔鱼的摄食强度及抵达不可逆点（PNR）时间的变化进行初步研究。
The feeding intensity during the period of 6:00-8:00 am and 16:00-18:00 pm was maximum. It seemed that the Cobia feeding rhythm was characterized by twilight feeding.
在白天的摄食中，又以早晨6：00-8：00和傍晚16：00-18：00摄食强度最大：夜间摄食较少或基本不摄食，所以军曹鱼早期幼体的摄食习性属白天摄食且偏于晨昏性类型。
Dry magnetic separators operation regulation note the main factors are: the feeding layer thickness (give ore amount), vibration slot vibration velocity, magnetic field intensity and working gap, etc.
干式磁选机的操作调节注意的主要因素是：给料层厚度(给矿量)、振动槽的振动速度、磁场强度和工作间隙等。
