First, it begins with the study of the centralized CFAR detection with multiple sensors. The non-CFAR problem is analyzed; the necessity for local CFAR processing is established. The effective local CFAR processing scheme is proposed, i.e. the local test statistic. The upper limit of the optimal performance is proved for the distributed CFAR detection based on LTS. Then, the new schemes based on LTS are analyzed in condition of signal pulse, and then the analysis is expanded to the case of multiple pulses. Next, the feedback mechanism is introduced. At last, the invariant test is used to reveal the essence of CFAR processing. It explains the necessity of local CFAR processing in the distributed CFAR detection at a higher level.

Cd〓 (1, 10, 100, 1000μM) stimulated directly GtH secretion from pituitary of common carp in vitro, with the highest GtH secretion at 100μM, GtH secretion stimulated with 1000μM Cd〓 was not higher than that stimulated with 100μM Cd〓.The antagonism between Ca〓 and Cd〓 in perfusion of the pituitary fragments was not obvious.After being preperfusion with 100μM Cd〓(with or without Ca〓), the GtH secretion of the pituitary fragment was irresponsive to 2-min pulse stmulation of 10μM sGnRH-A.

鲤鱼脑垂体碎片离体灌流孵育实验结果显示，Cd〓（1，10，100，1000μM）可直接刺激鲤鱼脑垂体分泌GtH，灌流液中Ca〓对Cd〓的拮抗作用不明显，100μM Cd〓刺激脑垂体分泌GtH达到高峰，Cd〓浓度增加到1000μM时，脑垂体分泌GtH并没有进一步增加，甚至有减少的趋势；100μM Cd〓预灌流脑垂体后，可使脑垂体对2-min 10μM sGnRH-A刺激的反应性消失；1.25mM的EDTA可消除100μM Cd〓刺激脑垂体分泌GtH的作用；TFP和Cd〓同时灌流脑垂体一段时间后，撤除TFP可使脑垂体分泌GtH显著增加，即出现"反跳"现象。
