Description
この数式では、剛体ロータとして扱われる二原子分子A−Bのエネルギーレベルは量子数Jで与えられる。この数式では、Δvは回転線の間隔であり、Bは回転定数であり、Iは換算質量μおよび結合距離に関する分子の慣性モーメントであり、Dは遠心力歪定数(cm−1)であり分子の剛性および分子の他のパラメータに応じて変わる値を有する。したがって、上記で説明した水銀種を含む対象の任意の所与の種に関して、THzスペクトルの吸収率のシフトは、未知の試料中にその特定の種が存在することを示す。
本明細書で開示した方法およびシステムを以下に例でさらに示しており、それら例はいかなる形にも限定するものとして解釈すべきではない。
Ybドープの超高速レーザが光パルスの放射のために使用される。レーザを参照ビームとしてのパルスを誘導するビームスプリッタおよびGaAsテラヘルツエミッタに接続するために光ファイバが使用される。次いで、参照ビームおよび生成したテラヘルツパルスを、ここでも光ファイバを用いて石炭火力発電所の燃焼排気に誘導する。燃焼排気では、生成したテラヘルツパルスは規定の距離だけガス流を通るように誘導されて、発生する燃焼排気ガスをリアルタイムでモニタリングする。次いで、パルスは再度回収され検出器に送信され、その検出器では参照ビームおよびテラヘルツパルスが分析され吸収信号に変換される。
例1のモニタリングシステムの構成は、リアルタイムの燃焼排気ガスの水銀濃度データをコンピュータワークステーション伝達するようになっている。ワークステーションでは、そのデータはグラフの形態で視覚的に提示され、そのため、ワークステーションのユーザが燃焼排気ガス中の水銀の放出を時間関数としてモニタリングすることが可能になる。
例1のモニタリングシステムの構成は、燃焼排気ガスの水銀濃度が所定の閾値を超えるときに、自動式のテキストメッセージを技術者に送信するようになっている。次いで、技術者は、テキストメッセージの受信時に、水銀減少システムを調節して燃焼排気ガス流中の水銀の捕集を改善するか、または燃焼排気ガス流中の水銀濃度を低下させるように燃焼工程を変更する。
いくつかの実施形態を例示および説明してきたが、それら実施形態には添付の特許請求の範囲で定義されるより広い態様における技術から逸脱することなく当業者により改変および修正を行うことができることを理解されたい。
