The simultaneous determination of refractive index and the wedge angle of an optical wedge plate is proposed.

光折变晶体是一种新型的记录材料，应用光折变效应，不需显影、定影等处理，就可实现实时观测。

Urification of Px showed that it had an apparent molecular weight of 10.3 kD.

x与DNA结合时也诱导DNA发生弯折，而且弯折的角度比NodD要大得多。

Discount rate for the calculation there are a lot of controversy in particular, the use of methods which discount rate the estimated return on assets that are reasonable, there are many theoretical point of view, the actual operation of the application of different papers from the asset valuation the theory and practice of starting.

而对于折现率的测算尤其存在许多的争议，采用哪种方法进行折现率即资产回报率的测算是合理的，理论界有很多的观点，实际操作中也有不同的应用本论文从资产评估理论和实践出发。

As he looked carefully now, he could see how folds of the old hanging bellied out where someone hid behind it.

他再仔细看看，看到这个古老绵织毯腹部，有明显的折痕，从这些折痕的样子看来，里面应该藏得有人。

Either of the folded ends of a book jacket that fit inside the front and back covers.

向内折的边：书籍护套折进封面或封底的折叠端的任一端

The anisotropic Bragg diffraction properties of volume gratings in photorefractive crystals were investigated by the method of the couple wave theory.

利用耦合波理论分析了光折变晶体中体光栅的各向异性衍射性能，研究了在不同初始记录光强比的条件下，记录光入射角的改变对光折变体光栅各向异性布喇格衍射性能的影响。

Both as to his dress and to himself, he was of an overlapping rhinoceros build, with folds in his cheeks, and his forehead, and his eyelids, and his lips, and his ears; but with bright, eager, childishly-inquiring grey eyes, under his ragged eyebrows, and broad-brimmed had.

从他的装束和他本人来看，都像是头满身皱折的犀牛，他的面颊上，额头上，眼皮上，嘴唇上和耳朵上，满都是皱折；但是，在他乱蓬蓬的眉毛和宽檐帽子下面，都是一双明亮，亲切，孩子般好奇的灰色的眼睛。

The materials containing carbazole components as a charge transporting function have been demonstrated to exhibit high performance photorefractive effects.

实验表明，具有良好光导电性的含咔唑基团的有机光折变材料显示出更好的光折变性能。

First we use the method of multiple scales tostudy local bifurcations of this system and obtain transition sets and bifurcating responsecurves.Then we use theory of normal form and universal unfolding and Melnikov'smethod to study further degenerate bifurcations of codimension two and globalbifurcations.

然后利用规范形理论、普适开折理论和Melnikov方法进一步研究了余维2退化分岔和全局分岔，并且获得了一些有意义的结果，提出了不完全普适开折的问题。

Methods］When scoliosis of patients were corrected to a certain degree after three weeks of halo pelvic distraction, the most serious collapsed ribs of concave side of the curve underwent a transverse incision the cross ribs. A special rib bender was used to bend the exposed 3 to 6 ribs. The bent ribs were pulled up by double-stranded 10# thick silk which was extended out through the skin and fixed in the upright post of the instrument of Halo pelvic distraction with rubber membranes.

方法］颅盆牵引3周后，脊柱侧弯矫正到一定程度时，在侧弯凹侧肋骨塌陷最重的部位，与肋骨交叉作横切口，暴露3～6条肋骨，用特制的肋骨折弯器将肋骨折弯变圆，用10号双股粗丝线将每条肋骨提起，自皮肤穿出通过橡皮膜在颅盆装置的立柱上作牵引。

I can't say anything hurtful about anyone.

我不能说任何伤害人左右。

She was a short fat woman , garbed in a very tight , very gaudy red dress .

大冬天的，我们穿两件毛衣她却穿件短袖，不停地扇扇子，一个劲叫热。
