The only source of light in the chamber—and with the topmost hatchway now closed, the only source of illumination at all—was a strange, glowing rectangle that shone against the far wall, a misty door painted on the wall in fitful yellowish light.

在这房间里，唯一的亮光——因为最上层的通道口现在关上了，也就是照在整个这第二层、第三层的光源——是在远处墙上闪光的、一个奇怪的矩形的发光体，是断断续续地黄色的光，在墙壁上描画出的一扇雾蒙蒙的门。

With American head lettuce as tested material, the rectangular hydroponic mode with gas-charged static nutrient solution was adopted, 6 different formula treatments including NO3(superscript -):NH4(superscript +)=80:20, 70:30, 60:40, 50:50; NO3(superscript -) replaced by CO (NH2) 2 as well as CK were set up and each formula was prepared by using groundwater directly to study the effects of different substitution amounts of nitrate nitrogen on growth status, root activity and chlorophyll content of lettuce.

方法］以美国结球生菜为试材，采用充气式静止营养液矩形水培方式，设定NO3：NH4=80：20，70：30，60：40，50：50；CO(NH2)2代替NO3以及对照共计6种不同的配方处理，各配方直接利用地下水进行配制，研究硝态氮不同替代量对生菜生长状况、根系活力和叶绿素含量的影响。

Tradition rectangular video are joined by circular and hexagonal works which can be turned.

在传统矩形视频的基础上加了可转动的圆形和六角形的表现。

The study shows that the pressure transient curve of fractured wells in closed circular formation can be divided into six different flow regimes. In condition of the same fracture opening width and fracture length, compared to rectangular fracture, the pressure drop with tapered fracture is bigger, and the dimensionless pressure and pressure derivative curves are higher. In condition of the same fracture opening permeability, compared to linear declining and constant conductivity fractures, the pressure drop with exponential declining conductivity fracture is the biggest, and the dimensionless pressure and pressure derivative curves are the highest.

研究结果表明：圆形封闭地层压裂井的压力动态曲线可以划分为6个流动阶段；在相同裂缝开口宽度和相同裂缝长度的条件下，与矩形裂缝相比，楔形裂缝压力消耗大，表现为无因次压力及压力导数曲线越高；在相同裂缝开口渗透率的条件下，与导流能力呈线性降低的裂缝以及常导流能力裂缝相比，导流能力呈幂指数降低的裂缝压力消耗最大，表现为无因次压力及压力导数曲线最高。

Then it cuts roughly the face picture into a rectangle outline by using horizontal projection method and transcendent knowledge of human face. Finally, it standardizes face image.

文中先通过垂直投影得到人脸的左右边界，再根据水平投影得到人脸额头的粗位置，并结合人脸的长宽比例的先验知识粗定位人脸矩形区域，最后标准化人脸图像。
