總屏蔽結構可采用銅絲銅帶組合屏蔽、銅絲編織屏蔽、銅帶屏蔽、銅絲編織銅帶屏蔽等，屏蔽層截面與主線芯截面按一定比例。此結構的屏蔽電纜可抗電磁感應、接地不良和電源線，減小電感，防止感應電動勢過大。

所謂的差分是指一根線以正電平傳輸，另外一根線

eth by the brothers de Valois, or rather by their intriguing mother, Catharine de Medici, he been related somewhat fully, mainly from the documents in the National Library in Paris, by the Count de la Ferrière,1 and the recent publication of the Spanish State Papers at Simancas of the reign of Elizabeth by the Record Office,2 puts us into session of a vast quantity of hitherto unused material of the highest interest, especially with regard to the matrimonial overtures made by Philip II. and the princes of the house of Austria; whilst the full text of the extraordinary private letters to and from the Queen in relation to the Alen?on match, 1579–82, printed by the Historical5 MSS. Commission from the Hatfield Papers, affords an opportunity of the greatest value for criticising the by-play in this curious comedy. From these sources, from the Walsingham Papers from the French diplomatic correspondence, from the Foreign, Domestic, and Venetian Calendars of State Papers, and from the various contemporary and later chroniclers of the times, it is proed to construct a consecutive narrative of mos

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(guī)定，成束 3.5m長的電纜試樣用鐵絲固定在梯形架上，試樣數(shù)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(yōu)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(yōu)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）。

The Swdish ambassador was to he been openly reproved by the Queen before the whole Court, but the Queen thought better of it, and received him in the presence of Gardiner and the21 Marquis of Winchester only. She diissed him curtly—almost rudely—and told him that after committing such a breach of etiquette as to deliver a letter to her sister before presenting his credentials, he had better go home and never come back to England with such a message as that again. Before Feria left England to see his in July, 1558, he visited Elizabeth at Hatfield, and did his best to persuade her that she had all Philip’s sympathy, and that her safe course would be to adhere to the Spanish connection. He was no match for her in diplomacy even then, and got nothing but iles and genial generalities. In November Mary was dying, and Dassonleville, the Flemish agent, wrote to the King begging him to send Feria back again to forward
