Description
[01] 本特許出願は、参照によりその内容を本明細書に援用する、2012年8月20日に出願された米国仮特許出願第61/684,991号の優先権の利益を米国特許法第119条(e)の下で主張する。
(1)Qpr=C(PO)γ
で表わすことができ、Qprは或る時点の予測流量を表し、Cはインターフェイス器具28における流れ口の伝導率(orifice conductance)を表し、POはその時点のインターフェイス器具28にわたる圧力を表し、γは圧力指数項を表す。導管26に沿って圧力が下がり、インターフェイス器具28が無視される場合、POは(例えば圧力発生器14の排気口における)圧力の測定値として概算され得る。
