凸的

The plasticity in a bas-relief is such that the features of a face in it can be prominent in both a convex and concave manner; what matters is that the extreme features are emphasized.

在一个可塑性的浅浮雕中也是如此，在那上面起着重要作用的脸部可以是凸的和凹的两个风格；所有起着极度重大作用的实质是强调音。

This book provides an in-depth, state-of-the-art discussion of the theory of finite packings and coverings by convex bodies.

这本书提供一个有限的包装材料的理论的详细，最新型的讨论和通过凸的身体包括。

However, because its feasible region is neither convex nor connected, this problem is intractable. Therefore, the nonlinear programming theory cannot be applied here directly.

然而该问题又是难解的，原因在于它的可行域既不是凸的又不是连通的，所以不能直接用现有的非线性规划理论来解决。

The convergence of the mean shift procedure to the closest mode of the underlying distribution is proven, both for the Epanechnikov kernel and the general case of kernels with convex and monotonic decreasing profile. The smooth trajectory property of the mean shift is also demonstrated.

均值平移算法对于Epanechnikov 核函数的收敛性在本文中得到了证明，进而推出均值平移算法收敛的充要条件是核函数具有凸的、单调递减性质的轮廓；揭示了均值平移过程运动轨迹的平滑性。

Furthermore, we determine the nonorientable crossing number sequences of those graphs by their crossing numbers on the projective plane and the embedding technique. Then we show that the nonorientable crossing number sequence of C(10,4) is non-convex.

利用子式理论的部分结果，证明了一些循环图C(10，4)，C(9，3)，C(8，3)在射影平面上的交叉数，再利用嵌入技巧，得到了它们的不可定向交叉数序列，并证明C(10，4)的不可定向交叉数序列不是凸的。

This paper discusses singularities, inflection points and convexity of FB-spline curves in terms of their control polygons, and gives the necessary and sufficient conditions for testing when FB-spline curves have one or two inflection points, or a cusp, or a loop, or none of the above points by the envelope theory and the topological mapping method.

文章利用包络理论和拓扑映射的方法，讨论了FB-样条曲线的奇拐点和曲线性质，并给出了依据控制多边形判断FB-样条曲线出现1个或2个拐点、1个尖点、1个二重点以及处处为凸的充分必要条件；最后给出了FB-样条曲线的奇点、拐点以及二重点在λ-μ平面上的分布图。

Spikelets green, ovate to obovate, plumply plano-convex, 2.5–3.5 mm, smooth, shining, obtuse; upper glume cartilaginous, 3-veined, glabrous; lower lemma resembling upper glume but slightly shorter; upper lemma pale green, slightly shorter than spikelet, finely striate, obtuse.

绿色的小穗，卵形到倒卵形，平凸的plumply，2.5-3.5毫米，平滑，发亮，钝；上面颖片软骨质，3脉，无毛；除了稍短，象上面颖片的更低的外稃；上面外稃苍绿色，稍短于小穗，细条纹，钝。

The bilateral asymmetry in force exerted on the scoliotic spine may be the cause.

双侧的不对称改变引起的肌肉组织力量的不对称可能是侧凸的原因之一。

If it's old and the filling is clumping up, it might be time to treat yourself to a new one.

看看你的枕头，太旧了，里面装的东西还一块块凹凹凸凸的，我想你该考虑换个新的了。

B-doing b-dang went that rubber band as I removed it to discover a precious collection of daguerreotypes, ambrotypes, tintypes, cartes-de-visite, cabinets and a plethora of 'real-photo' postcards.

我假装表现出对此没有兴趣，一边慢吞吞地走过一个包裹，这里面没什么只有退色的凹凹凸凸的摄影棚照片，照片里小女孩们站在毯子上手拿泰迪小熊，男孩子们背靠丰富的背景布拿着海边的水桶和铁楸。

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).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
