Mirror separates the light of different zones in multiple test blocks, while preventing from interfering, improves the utilization rate of light source, and
Allow and one variable of illumination condition is only existed when making experiment, it is ensured that the accuracy of experimental result.
2nd, controllable experimental flow field can be manufactured；Current can be accurate to each reality by this experimental provision by the fine setting to valve
Flow velocity needed for operating mode is tested, so as to avoid flow velocity unnecessary influence to caused by fish, improves experiment accuracy.
3rd, it is easy to operate；In experiment, it is only necessary to complete adjustment flow velocity, put fish and enter the two steps of test block.
4th, whole experimental provision is simple in construction, and material is generally cheap, reduces the cost of construction operation.
5th, monitoring is convenient, accurately.The present apparatus can accomplish to monitor in real time, by circuit stability and the shadow of reliability of mechanical equipment
Sound is extremely low.System operation, required state is easily kept for a long time.Regular maintenance technical difficulty is small, requires few to experimenter, phase
To simple.
