不幸

"The advantage of our method lies in the smallness, flexibility and precision with which the illuminated area of material can be chosen," Dwyer told nanotechweb.org."Hence, the experimentalist can precisely select the area of material she wants to analyse, and be confident that the surrounding areas are not interfering with her analysis."

对电子显微镜而言，由於物镜工作距离的限制，电子探针与样品常常无法同时被聚焦，因此大部分采用平行式探针的实验都是在探针离焦(out-of-focus)下进行，不幸的是，这种方法会产生如夫奈尔条纹之类多余的图形，因而不如易从绕射图形中精确选出待分析的样品体积。

If that happens, your program winds up in a tight infinite loop (entirely inside the extension module, so you cannot get at it with Python code directly).

如果不幸发生这种情况，你的程序将陷入一个紧密的无限循环中（完全位于扩展模块中，所以你不可能从Python代码中直接进入）。

Unfortunately, some of these colors require extensive inbreeding to obtain; double dapples are often born eyeless or with severely underdeveloped eyes.

Unfortunately, modifying the burn rate by this means is quite restrictive, as the performance of the propellant, as well as mechanical properties, are also greatly affected by the O/F ratio.

不幸的是，修改烧伤率由这意味着相当的限制，作为表现的推进剂，以及力学性能，也大大受影响的O /空燃比。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.
