此外,卤化体与空气中的水一旦反应后,即生成“卤化氢酸”,严重腐蚀仪器设备、建筑物造成“二次灾害”。
电缆长度:机械保护型电缆是根据相应基本电缆的长度制造。
ecise orders signed by the Queen as to the terms he might accept, “as he was determined not to deceive the Emperor.” At last, after infinite trouble, Sus was despatched at the end of June, 1567, bearing full instructions to negotiate the marriage. He was to raise no great difficulty except on two points: first the question of the Archduke’s income, and secondly that of religion. He was to say that “the Queen will take care that he wants for nothing, but she does not wish her people to think she had married a man too poor to keep himself.” The Archduke might privay hear Mass in his own chamber, but must conform outwardly to the law of England and accompany the Queen to Protestant service publicly.

accept the recommendation of the Guises as disinterested; and the matter went no further. The same agent suggests that the son of the Duke of Florence (Medici) who was then only eleven years old might do, and “if this party were liked it were an easy matter to be concluded without any excessive dote.” This was less likely to please even than the previous proal, and nothing was done; but the Ferrara family were apparently anxious for the connection, and early in 1553 Sir Richard Morysine,7 the English envoy in Antwerp, wrote to the Council reporting that Francesco d’Este, the brother of the Duke of Ferrara, had approached him on the matter and had asked for a description of the Princess. Morysine replied that “If God had made her Grace a poor man’s daughter he did not know of a prince that might not think himself happy to be the huand of such a lady,” and added that d’Este was of the same opinion “at present.”
