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

2．工頻電壓試驗(yàn)：交流50HZ3.5KV/5min不擊穿IEC阻燃等級：　　為了評定線纜的阻燃性能優(yōu)劣，分別制定了 IEC60332-1、IEC60332-2和IEC60332-3三個(gè)。IEC60332-1和IEC60332-2分別用來評定單根線纜按傾斜和垂直布放時(shí)的阻燃能力（國內(nèi)對應(yīng)GB12666.3和GB12666.4）。IEC60332-3（國內(nèi)對應(yīng)GB12666.5-90，GB12666.5已經(jīng)被GB/T 18380.3-2001代替）用來評定成束線纜垂直時(shí)的阻燃能力，相比之下成束線纜垂直時(shí)在阻燃能力的要求上要高得多。

religious matters will go on well, and the kingdom will remain friendly with your Majesty, but if not it will all be spoilt. If she decide to marry out of the country she will at once fix her eyes on your Majesty, although some of them here are sure to pitch upon the Archduke Ferdinand.”15 Feria was wrong in his estimate of Elizabeth’s character. From the first she had determined to be a popular sovereign, and all observers remarked her almost undignified anxiety to catch the cheers of the crowd. She knew that the most unpopular step she could take would be one that bound her interests to Spain, and particularly a marriage with Philip. A French marriage was imsible, for the heir to the crown of France was married to Mary Stuart, whose legal right to the English throne was undouedly stronger than that of Elizabeth herself.

一：導(dǎo)電線芯。柔軟性要求以電鉆電纜，采掘機(jī)電纜為高；導(dǎo)線結(jié)構(gòu)采取如下措施：  
1， 采用較軟的細(xì)直徑銅單線、以小節(jié)距束合、復(fù)絞。整根電纜的彎曲扭轉(zhuǎn)性還礦用電纜  MYQ-0.3/0.5 4*2.5受到絕緣、護(hù)套結(jié)構(gòu)的影響，因此不能認(rèn)為單絲越細(xì)，節(jié)距越小越好。  
2， 采用同向束絞和復(fù)絞可提高柔軟性。  
3， 為了便于導(dǎo)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(jī)電纜導(dǎo)線單絲應(yīng)鍍錫，大截面采掘機(jī)電纜在導(dǎo)線外還用包紙帶隔離絕緣。
