The invention discloses a complex plain river network generalization method achieving an approximately-uniform water storage relation. The method includes the steps that river channel geographic information data are obtained and processed; a simulated river network polygon is constructed; total water storage amount parameters of a generalized river network inside the simulated river network polygon are determined; the overlapping width of each simulated river sections of the river network polygon is determined; the width overlapping position of each river section of the river network polygon is determined. The water storage capacity of the generalized river network can be made to be approximately uniform with that of a prototype river network, simulation precision can be effectively improved, and the flood risk is easily analyzed; for the water administrative department in charge, defined data requirements are provided, and therefore data compiling is easily performed in management work of the plain river network; for scientific researchers in the water conservancy industry, the method is adopted for constructing a generalized river network hydrodynamic model, and in this way, it can be avoided that due to excessive dependency on experience, different researchers construct the model at different levels.

The present disclosure provides systems and methods for applying a volume gain to change the playback volume of a device by calculating a smoothed noise estimate. The smoothed noise estimate may calculated using an exponential smoothing method. The exponential smoothing method may include applying a weight factor to both a background noise estimate and a historical smoothed noise estimate. The weight factor may place more emphasis on either the background noise estimate or the historical smoothed noise estimate depending on the value of the weight factor. The value of the weight factor may change based on the type of environment the device is in, the speed of the background noise transitions, and/or historical data. The calculated smoothed noise estimate may be used to calculate a volume gain. The volume gain may be applied over a period of time such that the playback volume of the device changes smoothly.

The invention relates to a tea tree equal-height and synchronous-ripe sizing trimming method characterized by comprising four-rounds of trimming. Each time trimming work is conducted when a to-be-trimmed part grows mature; branches are irregularly trimmed according to ordered mature time; the trimming is conducted until all branches are trimmed for once; and the same round trimming is applied at the same horizontal height. By the use of the tea tree equal-height and synchronous-ripe sizing trimming method, tea garden closing can be accelerated and the tea garden can quickly go into operation; under the same condition, by the use of the method, the tea garden can be closed one to two years in advance compared with a traditional sizing trimming method.
