had quietly agreed with Leicester beforehand that her complaisance should not go beyond appearance, and before the fourite returned to Court Sackville’s departure had been indefiniy tponed. During Leicester’s absence from Court Cecil and Sus were more hopeful about the Archduke, although as we now see with very little reason. The Austrians were lethargic, the Spaniards coldly cautious, whilst the French were determined and unceasing in their efforts to thwart the Archduke’s suit. De Foix spent large sums in Leicester’s interest, and Catharine de Medici showered gifts and fours upon him constantly. The moment that he was in disgrace, however, or when the Archduke’s match seemed really progressing, they played their trump card in bringing forward Charles IX. again. When Rambouillet, the French envoy to Scotland, saw Elizabeth in February he had enlarged, by the Queen-mother’s orders, upon the vigour and comeliness of the young King. The105 Queen was always ready to listen to talk like this, and sighed that she would like to meet him, “but,” she said, “do y

中要求1、2、3、6、4、5、7、8線必須是雙絞。這是因為,在數(shù)據(jù)的傳輸中,為了和外界的,發(fā)送和接收的數(shù)據(jù)均以差分傳輸,即每一對線互相扭在一起傳輸一路差分信 號(這也是雙絞線名稱的由來)。
在傳輸中可以采用中繼的對進行放大,多可以加八個中繼,也就是說理論上RS485的傳輸距離可以達到9.6公里。

to reign. The combination of circumstances on the Continent also seems to he been exactly that necessary to aid the result most fourable to English interests; and the special personal qualities3 both of Philip II. and Catharine de Medici were as if expressly moulded to contribute to the same end. But propitious, almost providential, as the circumstances were, the of England and the establishment of Protestanti as a permanent power in Europe could never he been effected without the supreme and sustained statecraft of the Queen and her great minister. The nimble shifting from side to side, the encouragement or discouragement of the French and Flemish Protestants as the policy of the moment dictated, the alternate flouting and flattering of the rival powers, and the agile utilisation of the Queen’s and feminine love of admiration to provoke competing offers for her hand, all exhibit stateanship as keen as it was unscrupulous. The political methods adopted were perhaps those which met with general acceptance at the time, but the dexterous juggling through a long course of years with regard to Elizabeth’s marriage is unexampled in the history of government. Not a point was missed. Full advantage was taken of the Queen’s maiden state, of her feminine fickleness, of her solitary sovereignty, of her assumed religious uncertainty, of her accepted beauty,

礦用橡套電纜結構特點:一:導電線芯。柔軟性要求以電鉆電纜,采掘機電纜為高;導線結構采取如下措施:1,采用較軟的細直徑銅單線、以小節(jié)距束合、復絞。整根電纜的彎曲扭轉性還受到絕緣、護套結構的影響,因此不能認為單絲越細,節(jié)距越小越好。2,采用同向束絞和復絞可提高柔軟性。3,為了便于導線在絕緣層中的相對滑動和便于安裝維修。電鉆電纜和小截面的采掘機電纜導線單絲應鍍錫,大截面采掘機電纜在導線外還用包紙帶隔離絕緣。二:絕緣層要求有足夠的電絕緣性能1,采用含膠量不低于百分之35的橡皮2,絕緣厚度比通用橡套電纜要厚3,采用電性好的橡皮,并采用好的擠橡工藝(如擠橡硫化連續(xù)生產線)
