The invention relates to a coating system and a coating method, especially to a dynamic / static hybrid coating system and a dynamic / static hybrid coating method by the utilization of the dynamic / static hybrid coating system. The dynamic / static hybrid coating system comprises a static coating system and a dynamic coating system. The static coating system contains a static coating chamber, a first coating assembly and a first transmission assembly. The reciprocating scan distance is zero or any distance less than the spacing between adjacent target materials. The dynamic coating system contains a dynamic coating chamber, a second coating assembly and a second transmission assembly. The dynamic / static hybrid coating method contains two modes. The first mode is as follows: static coating comes first and dynamic coating follows; then vertical transition of a substrate is conducted and the substrate comes out in a reverse direction; and the substrate is uncoated after translation. The second mode is as follows: the substrate firstly enters the innermost chamber; static coating is conducted after vertical transition; then, the substrate comes out in a reverse direction for dynamic coating; and finally, the substrate comes out from a low vacuum chamber. By the system and the method, a substrate can be coated and coating is uniform. Electrostatic damage to an electrostatic sensitive device can be prevented.

The invention provides an ultrasonic emulsification feeding device and a feeding method for cigarettes. After a whole batch of feed liquid all enters a material storage tank, the feed liquid enters a gear pump through an suction end of the gear pump, the feed liquid is stirred and pre-mixed through rotation of a gear in the gear pump, the feed liquid which is even in the whole is quantitatively pumped into an ultrasonic emulgator through the gear pump to conduct superfine emulsification, a particle granulometer conducts a grading analysis to the feed liquid which is processed by the ultrasonic emulgator, the particle size of the measured feed liquid is conveyed to a controller, the controller conducts comparison with a granularity threshold value which is pre-stored according to the particle size which is conveyed by the particle granulometer, and if the particle size is larger than the granularity threshold value which is pre-stored, the controller enables a double-way valve to be adjusted to the direction of a return pipe, otherwise, the controller enables the double-way valve to be adjusted to the direction of a material discharge pipe. The device expands the use range of flavor, and turbid liquid, oily feed liquid, solid particle flavor with small particles all can be added through the method, and therefore evenness, stability, high technology precision are achieved.

This invention relates to TDS-OFDM receiver time-varying channel estimation and the balance method and system which assumes the channel varies in linearity in an OFDM block. Firstly a channel response estimation at the PN of each OFDM block is got by PN code time domain then to carry out linear interpolating in the OFDM block to get the entire channel response estimation. This invention puts forward a simplified balance method for complementing the balance matrix with ICI to carry out spreading of finite item power series, which greatly increases the receiving performance of TDS-OFDM receivers under time-varying channel and is better than the scheme of assuming the channel unchanged in an OFDM block.
