【题解及原文】歌颂周文王能任用贤人,征伐诸侯,治理四方。 芃芃棫朴,薪之槱之。济济辟王,左右趣之。 济济辟王,左右。峨峨,髦士攸宜。 淠彼泾舟,烝徒楫之。周王于迈,六师及之。 倬彼云汉,为章于天。周王寿考,遐不作人? 追琢其章,金玉其相。勉勉我王,纲纪四方。 【注释】 1、芃芃(彭péng):《毛传》:“芃芃,木盛貌。” 棫(域yù):白桵(蕊ruǐ),小木,丛生有刺。 2、槱(有yǒu):堆积木柴,点火以祭。《说文?木部》:“槱,积木燎也。” 3、辟王:君王,指周文王。 4、璋:《通释》:“《白虎通义》曰:‘璋以发兵何?璋半圭,位在南方,阳极而阴始,起兵亦阴也,故以发兵也。’拾古用以发兵。” 5、峨峨:《毛传》:“峨峨,貌。” 6、髦士:英俊之士。《毛传》:“髦,俊也。” 7、淠(必bì):船行摇晃貌。《毛传》:“淠,舟行貌。”《集疏》:“军舟浮泾而行,众徒鼓楫(即jí),水声淠淠然也。” 8、烝(蒸zhēng):众。徒:船夫。 9、周王于迈:《春秋繁露?四祭》:“周王于迈,六师及之,此文王之伐崇也。” 10、倬(卓zhuō):广大。《说文?人部》:“倬,箸(著zhù)大也。” 11、作人:《正义》:“作人者,变旧造新之意。” 12、追(堆duī):雕。《毛传》:“追,雕也。”陈启源《毛诗稽古编》:“章,周王之文也。相,周王之质也。追琢者其文,比其修饰也。金玉者其质,比其精纯也。” 13、我王:《郑笺》:“我王,谓文王也。以网罟(古gǔ)喻为政,张之为纲,理之为纪。”

一、输入回路的设计 1、电源回路 PLC供电电源一般为 AC85—240V(也有DC24V),适应电源范围较宽,但为了抗,应加装电源净化元件(如电源滤波器、1:1隔离变压器等)。 2、PLC上DC24V电源的使用各公司 PLC产品上一般都有DC24V电源,但该电源容量小,为几十毫安至几百毫安,用其带负载时要注意容量,同时作好防短路措施(因为该电源的过载或短路都将影响PLC的运行)。 3、外部DC24V电源 若输入回路有 DC24V供电的接近开关、光电开关等,而PLC上DC24V电源容量不够时,要从外部提供DC24V电源;但该电源的“—”端不要与 PLC的 DC24V的“—”端以及“COM”端相连,否则会影响PLC的运行。 4、输入的灵敏度各厂家对PLC的输人端电压和电流都有规定,如三菱公司F7n系列PLC的输入值为:DC24V、7mA,启动电流为4.5mA,关 断电流小于1.5mA,因此,当输入回路串有二极管或电阻(不能完全启动),或者有并联电阻或有漏电流时(不能完全切断),就会有误,灵敏度下降,对 此应采取措施。另一方面,当输入器件的输入电流大于PLC的大输入电流时,也会引起误,应采用弱电流的输入器件,并且选用输人为共漏型输入的 PLC,Bp输入元件的公共点电位相对为负,电流是 PLC的输入端。
