The emergence of an H5N1 strain that is readily transmitted among humans would mark the start of a pandemic.

在人中间可容易地传播的H5N1株的出现将标志着一次大流行的开始。

The experimental result indicated that: in stretch process, in identical test specimen the strain value on metal substrate and contact surface are same, the mark is opposite.

实验结果表明：在拉伸过程中，同一试样中金属基体上和界面上的应变数值相同，符号相反。

The stamping simulation technology could predict the material flow and the strain distribution, so the initial mark location and shape could be calculated.

Conservative MP Mark Reckless said the financial strain was down to the previous government's record debts.

It was reported that Mark had shown signs of strain with pending litigation and an isolated lifestyle as a result of many of his close friends losing money in the Madoff scam.
