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

阻燃電纜 ：◎ IEC60332-3/BS4066-3阻燃等級（成束電線或電纜垂直 Flame On BunchedWires/Cables）　這是成束電纜的。試驗規定，成束 3.5m長的電纜試樣用鐵絲固定在梯形架上，試樣數量按不同分類所要求的非金屬物料決定。試樣垂直掛在爐背壁上，空氣通過底板上的進氣口引入爐。丙烷平面器以750℃的火焰與試樣，試樣在強制吹風（氣流排放5m3/分鐘，風速0.9m/秒）的情況下，必須在垂直20分鐘內燃不起來，電纜在火焰蔓延2.5米以內自行熄滅。IEC60332有A類、B類、C類和D類之分，以評定阻燃性能優劣。

通信電纜與架空明線相比，具有通信容量大、傳輸性高、保密性好、少受自然條件和外部影響等優點。是由多根互相絕緣的導線或導體絞襯纜心和保護纜心不時與機械損害的外層護套所構襯通信線路。由多根互相絕緣的導線或導體構成纜芯，外部具有密封護套的通信線路。有的在護套外冒有外護層。有架空、直埋、管道和水底等多種敷設。按結構分為對稱、同軸和綜合電纜；按功能分為和永備電纜（地下、海底電纜）。
that at one juncture he had sed her life, and it is highly probable that the Princess was released from the Tower in May, 1554 on the recommendation of Renard, made in the name of the coming bridegroom of the Queen. De Noailles writes that she was to go to Richmond from the Tower, and was there to receive two gentlemen from the Emperor who were to sound her as to a marriage with Emmanuel of Soy. If she refused the match she was to be taken to Woodstock under guard, again a prisoner. De Noailles knew that the best way of preventing such a match was to arouse the Queen’s18 suspicion that Elizabeth was plotting with the French. So with devilish ingenuity he sent a man with a present of apples to the Princess to meet her on her arrival at Richmond
