查询词典 plane convex

This algorithm is proposed on the basis of the thought as follovvs: as for three dimensional Euclid space, the feasible region of any linear programming problem is a extended convex polyhedron, of which surface is consisted of some planes, and its objective function can be regarded as a parallel plane pencil with objective function value acting as parameter.

如果线性规划问题有最优解，那么过可行域的一已知顶点必至少存在这样一条棱——它以该己知顶点为一端点，可行域的另一顶点为另一端点，并使目标函数在另一端点的函数值优于己知端点的函数值，否则，该己知点就是线性规划问题的最优解。

Is a kind artistic school, Modern artistic embroidery advocate fully is not embroidery do not enter a picture, All a picture have embroidery to be completed; A little use, even not using outside ornaments, Unless as a last resort, can develop to bring the painted dragon to life in the pupils of its eyes role; color line is covered a picture, Pursue the combination of line and color piece is artistic true, The combination of plane and convex has the impact on vision; Changeful needle law, line a picture, Make works very durable to see.

作为一种艺术流派，现代艺术刺绣主张非刺绣莫上画，形象设计和氛围烘托全部由刺绣来完成；尽量少用甚至不用非刺绣饰物；色线布满画面，线条和色块的组合追求艺术的真实，平凸的组合具备视觉上的冲击力；多变的针法、细腻的画面，把作品在各种情况下的观赏性推向极至。

The formula for area of ellipsoidal triangle on earth ellipsoid by means of geodesic coordinate is derived in this paper. It is showed that the primary term is identical with the formula for area of plane triangle by planimetric rectangular coordinate in three angular point, while the expression of remainder terms has also regularity of its form. The presented formula can be applicable also to convex polygon on earth ellipsoid.

本文推导出用三顶点的测地坐标计算地球椭球面上三角形面积的公式，公式表明，其主项的表示式与按平面坐标求面积的计算式完全一致，而附加项的表示式亦有规律可循，因此该公式的适用范围可由椭球面三角形推广至椭球面上任意凸多边形。

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
