We select Blumlein circuit as the fast pulse discharge circuit,by designing proper circuit structure,adopting wide leading wire in place of the transmission line,reducing parasitic inductance of discharge loop,steady fast pulse discharge has been gained,it meets the demand to discharge current and is good for S_2 laser.

Some problems in automatic production of small Al electrolytic capacitors,such as unstablestatic capacitance,increased tgδand dc current leakage,etc,were analyzed,and some satisfactary resolutions,such as reducing anode foil specific capaCity and wire width are presented.

To resolve the large time jitter error of middle-long range action in UWB fuse systems,a novel time system base on crystal frequency division has been proposed.

Proposes a Backus-Naur Form(BNF) based methodology for the design of metropolitan area environment surveillance system,which is underpinned by the broadband wireless network technology.

But wide-area Broadband Wireless Access Network (BWAN) can effectively solve this problem, therefore, wide-area Broadband Wireless Access Network becomes one of the most important projects of digital city construction.

This article installs the environment in view of the ships special antenna, analyzed the short wave wide band antenna to install with emphasis after the ships, installed the environment the influence which produced to its standing wave and the gain.

Literature Review on Wireless Broadband Network Technology:WiMAX Technology;

Middleware Technique of Wireless Broadband Applications;

HSPA is one of the most promising among them and will probably become the leading one in the wireless broadband market, while other broadband wireless access technologies such as WiMAX will gain some certain market share.
