「全球最大核電廠」突起火冒煙! 日本消防廳緊急救援防輻射外洩

日本新潟縣柏崎刈羽核電廠6號機10日上午驚傳冒煙,位置在機組1樓的緊急柴油發電機控制盤室。東京電力公司立即進行初步滅火,現已以取得控制,所幸這起事故未對外造成輻射影響。
綜合NHK等日媒,東電說明,核電廠員工約於10日上午10時發現6號機控制盤室正在冒煙,隨即通報消防單位。該控制盤室位於6號機反應爐廠房內的非輻射管制區,東電迅速採取初步滅火措施。

The Log Periodic Antenna as known as LPDA is a wideband directional antenna that provides gain and directivity combined over a wide band of frequencies.
Both Log-Periodic Antennas and Yagi antennas are high gain directional antennas. The main difference between these antennas is that Log-Periodic Antennas support wider frequency bandwidths and are physically much larger than Yagi antennas.
The log-periodic dipole array typical VSWR is 2:1 and operates over a much wider bandwidth and will have a lower gain for an equivalent number of elements.
With this level of performance, it is ideal for many applications, although a log-periodic antenna will be much larger than a Yagi of an equivalent gain.
