er over the miserable Mary in the last sad months of her life, and Elizabeth’s star rose, suitors became more plentiful. At the beginning of 1558 Philip had sent haughty Feria as his ambassador to his wife to drive her into providing men and money to help him in his war against France. Calais and Guisnes had just been lost to England, and Mary, all her hopes and illusions fled, was fretting her heart out in despair. In April an ambassador arrived from the King of Sweden, Gustus, with letters to the Queen proing a treaty of commerce between the two countries, and the marriage of his eldest son,20 Eric, with Princess Elizabeth. The ambassador was in no hurry to seek aunce of the Queen—her day was already on the wane—but ted down to Hatfield to see the Princess, to whom he delivered a letter from Prince Eric himself. The Queen was overcome with rage at this and with fear that Philip would blame her for refusing his request to restore Elizabeth in blood and marry her to Emmanuel of Soy, and thus giving rise to this embarrassing Swedish offer. Hearing that Feria was about to send a courier to Flanders, she summoned him, and in a violent passion of tears reproached him with w

而耐火电缆通常是在导体与绝缘层之间再加1个耐火层,所以从理论上讲可以在阻燃电缆的结构中加上耐火层,就形成了既阻燃又耐火的电缆,但实际并没有这个必要。

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 r

矿用橡套电缆结构特点:一:导电线芯。柔软性要求以电钻电缆,采掘机电缆为高;导线结构采取如下措施:1,采用较软的细直径铜单线、以小节距束合、复绞。整根电缆的弯曲扭转性还受到绝缘、护套结构的影响,因此不能认为单丝越细,节距越小越好。2,采用同向束绞和复绞可提高柔软性。3,为了便于导线在绝缘层中的相对滑动和便于安装维修。电钻电缆和小截面的采掘机电缆导线单丝应镀锡,大截面采掘机电缆在导线外还用包纸带隔离绝缘。二:绝缘层要求有足够的电绝缘性能1,采用含胶量不低于百分之35的橡皮2,绝缘厚度比通用橡套电缆要厚3,采用电性好的橡皮,并采用好的挤橡工艺(如挤橡硫化连续生产线)
