查询词典 obtuse angle

When to take four samples in one tree, commonly the samples are taken in "cross" relation, but the analysis shows it is not the best choice. The more the samples are taken at obtuse angle with each other, the better the representation of the samples.

在两个或者3个方位采样时，方位之间呈钝角关系时，其代表性最好。4个方位采样时，一般使用的"十字交叉法"并不是最好的选择，建议采样的方位之间尽可能多的成钝角关系。

To address the issue, we analyze the correlation and similarity of the different radii sequence and the different combination sequence with the full- ring-sample sequences, based on 642 δ13C data of cellulose fixed in tree-ring at 8 different radii of two Cryptomeria fortunei tree disks from Mt. Tianmu, a subtropical mountain of China. It suggests that 2 to 4 radii mixture sample is the better and more efficient choice for the tree-ring δ13C analysis. It had better to take samples at obtuse angle with each other when to take samples at two or three radii.

研究利用来自天目山的两个柳杉树盘的多方位的和整轮的碳同位素测试数据（共计642个），通过不同方位和不同方位组合的平均碳同位素序列与整轮碳同位素序列的关系的多角度的考查、分析发现，并不是采样的方位数越多越好，选择2~4个方位采样合并分析树轮稳定碳同位素，既经济方便又能比较好的反映一棵树的δ13C变化过程与趋势。

It has been obtained that the distortion characteristics of the gently-slant rock mainly include asymmetrical distortion and obtuse angle destruction.

尝试采用以板状单元模拟缓倾层状岩体，对徐州矿区旗山矿缓倾（8°）层状岩体的产状及结构性特征进行模拟，再现了巷道的破坏全过程。

Some constraints are selected, and omitted according to the most-obtuse-angle principle. The smaller problem is solved with the simplex method. Then the omitted constraints are added to restore the original problem. If all the constraints are satisfied, then a basic optimal solution is reached. In the other case, the dual simplex method is used to obtain the basic optimal solution.

该算法依据最钝角原理略去部分约束得到一个规模较小的子问题，用原始单纯形算法解之；再添加所略去的约束恢复原问题，若此时全部约束条件均满足则已获得一个基本最优解，否则用对偶单纯形算法继续求解。
