查询词典 normal surface

Our skin every day on their own metabolism, resulting from the basal cells gradually reach the skin surface, and then become a cuticle, the skin hyperkeratosis cycle is usually around 28 days, due to the environment, season, UV, rest is not normal and other factors, sometimes cause slow metabolism, so our skin piles up thicker stratum corneum, horny excessive accumulation, it will allow a transparent discussion so that the skin does not feel a sense of, and have lost the flexibility of the original, so fixed and the appropriate exfoliation, dander can be removed, so that the skin is more translucent.

我们的肌肤每天都会自行新陈代谢，由基底层产生的细胞会慢慢的到达肌肤的表面，然后成为角质层，皮肤的角化周期通常约为28天，由于环境、季节、紫外线、作息不正常等因素，有时会使新陈代谢变得缓慢，所以我们的皮肤表面角质层越堆越厚，角质过度的堆积，就会容议让肌肤感觉没有透明感，也失去原本的弹性，所以固定且适当的去角质，可以将皮屑去除，让肌肤更晶莹剔透。

Image's brightness changes by the angle between the surface normal and illuminant direction.

图象的亮度随物体表面法方向与光照方向之间夹角的变化而改变。

The angle between an incident ray and the normal to a reflecting or refracting surface.

应用梯度理论和状态方程（Peng－Robinson方程与Patel－Teja方程）相结合的半理论方法，计算了正构烷烃的表面张力，提出了关联作用参数C的新方程。

The results show that, the distribution of magnetic field and electromagnetic force in the aluminum film on the cathode slope are in symmetry to the long axis of the cell, especially the magnetic force is in the same direction as the gravity force, which is in favor of the aluminum discharging from the cathode slope. The highest fluctuation of aluminum pad surface in the accumulation sump is 0.021 m, which still remains within the safe range, and will not cause interpolar short circuit, so a normal operation process could be maintained with the same bus bar configuration as the current 75 kA aluminum reduction cells.

结果表明：阴极斜坡表面电磁场和电磁力场分布基本呈沿电解槽长轴对称分布，且电磁力与重力方向相同，这有利于阴极表面电磁力向聚铝沟排放，而在电磁力作用下，聚铝沟内铝液波动最大幅度为0.021 m，仍保持在安全范围之内，不会引起两极短路现象的发生，表明在现有75 kA普通预焙槽母线配置方案下，可以维持导流型结构电解槽的正常运行。

And, normal keratinization can be observed by scanning electron microscape on the surface of the PCS.

通过冻干法制备的蛋白改性壳聚糖多孔支架对细胞没有毒性，L929细胞和人成纤维细胞可以在支架表面和内部正常生长和增殖，角质细胞在材料表面可以正常老化、角质化。

The law of refraction, discovered first empirically by Willebrord SNELL, then subsequently derived formally by Descartes and Fermat, states that sin r = K sin i, where i is called the angle of incidence, the angle between the incident ray and the normal to the refracting surface.

折射的轨律，首先被 Willebrord SNELL 靠经验发现，接着后来正式被笛卡尔和 Fermat 认定，规定 sin r = K sin i ，这里 i 被称作入射角，入射光线和法线到折射平面之间的夹角。

After introducing the primary approximation approaches for curve and surface offset, we give an optimal approximation approach for offsetting curve based on shifting control points, which relies on approximating the normal by Legendre polynomial approximation.

在全面介绍了等距曲线曲面逼近的主要方法以后，作者首先利用Legendre多项式得到基曲线法矢曲线的最佳平方逼近，由此给出了基于控制顶点偏移的等距曲线最优逼近的算法，它在算法效果和效率上都远优于其他同类算法。

The line of curvature is relation to many basic conception with curve and surface, by which normal curvature and principal curvature are easier.

曲率线将曲线与曲面中的许多基本概念有机地联系起来，使得法曲率和主曲率的求解简单化。
