你可以通过聚焦随机性和不确定性来放弃对你自己实相的控制，但是你无论如何也逃避不了你该承担的责任。

It is pointed out that if we don′t take into account therefrangibility of the high-order excited state, the material is self-defocusing whenthe refrangibility of the ground state is larger than that of the excited state andself-focusing if it is smaller.

指出如果不考虑高阶激发态折射，基态折射度大于激发态折射度为自散焦，小于激发态折射度为自聚焦。

Brandon concentrates more on Wollstonecraft's achievements and adventures than on her work in the schoolroom.

However, as the research of the technique of High Intensity Focused Ultrasound more and more advanced, people found that the theory of how to improve the success and efficiency of ultrasonic thermotherapy is unripe. The problem include following aspects.

然而，随着对高强度聚焦超声技术研究的不断深入，发现在超声热疗的过程中，关于如何提高超声热疗的治愈成功率和治疗效率的相关理论还不成熟。

Timbal's Focusing Crystal — Oh god yes, easily the best shadow priest trinket for PvP (I think it's one of the best if not the best for PvE too?).

This is a valuable tool. If you are struggling with a background that competes with the foreground, look at whether either has linear detail (say, a squirrel on a tree branch). You can activate one of the rectangles and turn the camera so that the rectangle is either parallel with the linear detail that you want to ignore or perpendicular to the detail you want to focus on.

这一点很重要，在对前后景完全混杂的影像聚焦遇到困难时，试着找找线状细节，你可以激活某个对焦点并转动相机，使得对焦框与你不需要的影像平行，或者与需要对焦的影像垂直就可以了。

Compare, for example, the optical designs of the 17th century physicists Descartes and Huygens shown below, with those of two trilobite species. The result is that, even without the benefit of accomodation, the rigid trilobite doublet lens had remarkable depth of field (that is, allowed for objects both near and far to remain in relatively good focus) and minimal spherical aberration.

相比较而言，有一个很好的例子，在17世纪，物理学家迪卡尔和惠更斯同样展示了这种视觉构造，这刚性的三叶虫的眼睛，有着不寻常的景深（在观察近的以及远的物体能同样的聚焦），另外它还具有最小的球状像畸。

But the human mind can glimpse a rapidly changing scene and immediately disregard the 98 percent that is irrele vant, instantaneously focusing on the monkey at the side of a winding forest road or the single suspicious face in a big cro wd.

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).
