小平面

Etching method applied to large-quantity, variety, large flat thin metal material processing and metal product surface decoration process (semi-corrosion), but also applies to single-piece and small-batch sampling.

蚀刻法适用于批量大、品种多、大平面的薄型金属材料加工和金属制品表面工艺装饰，同时也适用于单件小批打样。

Opengl small examples shadow and achieve smooth plane.

The precision tracking for the "S maneuver" targets in 2-D plane was realized by the Monte Carlo simulation, and the root mean square error of position is much smaller than the Singer model.

通过Monte Carlo仿真，实现了在平面内对&蛇形&机动目标位置的准确跟踪，并且距离均方根误差比Singer模型要小很多，从而验证了该方法的有效性。

By using geometry, we find the distance between the hyperplanes is 2/|'''''w'''''|, so we want to minimize |'''''w'''''|.

通过几何不难得到这两个超平面之间的距离是 1/2|'''''w'''''|，因此我们需要最小化|'''''w'''''|。

Rat tails: Long, Narrow, linear depressions or small steps occurring on the casting surface due to sand expansion and minor buckling of the mode surface during filling of the mold with liquid metal.

Based on the modeling theory of the equivalent probability density error model(marked as "Tepdem") and the numerical algorithm,this paper provides an approach on how to ascertain a point location with the highest coordinates precision between both of the adjacent characteristic points on a generic curve accurately by use of the theory of function extremum as well as the iterative algorithm,and it also provides the method on how to obtain the least width of "Tepdem" exactly,from which,the explanation of geom...

基于等概率密度误差模型建模原理和数值算法，运用函数极值理论和迭代方法来求解平面一般曲线上两相邻特征点间位置精度最高的点，以精确确定误差模型的最小带宽，从理论上给出等概率密度误差模型的几何特征，从而进一步完善矢量GIS的位置不确定性理论。通过实例计算与可视化分析，验证了理论推导的正确性。

Ancient Roman furniture design is a variant of the Greek style, heavy furniture, decorative complex, sophisticated, the use of mosaics and sculpture, a flat spin ability to walk, animal feet, with a winged sphinx and the Gryphon body of the monster, as displayed in table or dining, legs and feet have small support, the back panel is concave; in furniture in a combination of architectural features, using the construction approach, three leg table and the base is widespread, the use of precious fabrics and cushion.

古罗马家具的设计，是希腊风格的变异，沉重的家具，装饰复杂，发达，马赛克和雕塑，平面旋转行走能力的使用，动物的脚，有翅膀的狮身人面像和怪物狮体，如表或用餐，腿和脚有小的支持下，背面是凹显示，在家具的建筑特色相结合，利用施工方法，三腿表和基础广泛，在使用和珍贵织物垫。

Thirdly, by con-utilaziont of many methods such as exploitation and geology, dynamic producing process monitoring, water invasion behavior, core analyis and numerical simulation, 10 kinds of reservoir scale remaining oil distribution pattern in the steam huff and puff super heavy crude oil reservoir was put forward. Also, remainling oil distribution in the sand bed scale and sublayer scale were pointed out.Fourthly, Microcosmic displacement experiment was conducted for hot water driving in 100℃and 120℃. and steam drive at 170℃condition. Microcosmic remaining oil distribution characteristics were summarized. Remaining oil microcosmic distribution by steam drive at 170℃is different from that at 100℃, 120℃hot water driving. After the steam drive, there are three types of remaining oil distribute regular pattern, whic is impacted by many affecting factors like pore configuration, wettability and interfacial tension.

分析了砂层组规模和小层规模的纵向和平面剩余油分布规律。4、通过微观驱替实验，研究了100℃和120℃的热水驱及170℃蒸汽驱条件下剩余油的微观分布形态。170℃条件下剩余油微观分布形态同时受孔隙结构、润湿性及界面张力多种因素的影响，主要有三种形式：在油、汽、水三相共存的孔隙中，剩余油分布于汽、水之间，为薄膜状和弯月状；在只有油、汽两相共存的孔隙中，大孔道中主要是蒸汽，剩余油在细小的孔喉和孔隙角隅处以段塞或不规则状态存在；由于高温水蒸汽对原油具有萃取作用，剩余油以一种细小的珠滴状存在于孔隙表面。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.
