查询词典 condition number

Floor of entire county total ground accumulates 4885 square kilometer, climate characteristic is spring dry sand blown by wind is much, the summer is short rainfall is little, year average air temperature 2.5 ℃, fall 350mm is controlled, frost-free period is controlled 110 days, it is typical dry farming county, long-term since, because the ploughshare type of follow tradition plows cultivation, a large number of the earth's surface are completely bare, monsoon comes, soil land of medium fine sanded face is reached organic blow character, cause edaphic sand to change, fertility drops, raise of sand and dust, year answer a year, change dene serious with each passing day, cause aggravation of zoology environment year after year, the agriculture that also decided place produces a condition, groundwater source is not worth badly, 10 years of 9 drought, extensive cultivation, crop yield is low and flabby.

全县总土地面积4885平方公里，气候特色为春季干燥风沙多，夏季短促降雨少，年平均气温2.5℃，降水量350mm左右，无霜期110天左右，是典型的旱作农业县，长期以来，由于沿袭传统的铧式犁耕作，大量地表完全裸露，季风来临，将土壤中的细沙面土及有机质刮走，造成土壤沙化、肥力下降，沙尘扬起，年复一年，沙化日趋严重，造成生态环境逐年恶化，也决定了当地的农业生产条件，地下水源严重不足，十年九旱，广种薄收，作物产量低而不稳。

The result shows that, under the condition of the same thickness of material, increasing the number of layers properly can weaken the press, the cutting damage and the destruction due to extension, and lower the impact energy on the construction effectively. In particular, multi-layered protection construction is rather striking in its advantage of destruction-resistance under high stress and low impulse load.

结果表明，分层总厚度相等的条件下，适当增加分层数目可以有效减小冲击载荷对结构的压、剪损伤和拉伸破坏，降低结构所受的冲击能量，尤其对于高强度、持续时间短的脉冲载荷，多分层防护结构的抗毁伤能力优势更为明显。

This number is significant in the control and prevention of this condition.

这个数字的意义，控制和预防这种情况。

The plastic deformation induced due to cyclic rotation of principal stress axes alone can be in the same magnitude as that due to shear with fixed principal stress axes. 2 The volumetric strain due to shearing of cyclic rotation of principal stress axes is found to be composed of a reversible dilatancy component and an irreversible dilatancy component. The former is characterized by its reversibility and is independent of past shear history, the latter by its irreversibility increases with the increase of cycle number yet its increase rate decreases with its accumulation. 3 The obvious non-coaxiality between directions of the principal stresses and principal strain increments is found and its degree depends largely on the change of shear stress component. 4 The intermediate principal stress has considerable effects on the deformation behavior of sands in the condition of cyclic rotation of principal stress axes. The accumulation rate of the irreversible dilatancy component increases with the increase of the intermediate principal stress parameter.

具有初始各向异性的砂土在纯应力主轴循环旋转排水条件下的主要变形规律为：①纯应力主轴循环旋转可产生与应力主轴固定单调剪切处于同一数量级的塑性变形；②纯应力主轴循环旋转引起的剪切体变包含可逆性剪切体变分量和不可逆性剪切体变分量两部分，其中可逆性剪切体变分量在一周内可完全恢复，基本与应力历史无关；不可逆性剪切体变分量随循环周数的增加呈单调增加，且增加速率随其自身累积值的增大呈减小趋势；③应变增量主轴与应力主轴之间的非共轴现象显著，且在一周内具有分段性；④中主应力对应力主轴循环旋转条件下砂土的变形特性有重要影响，不可逆性剪切体变分量的累积速率随中主应力系数的增加而增加。

First, based on the analysis of the grid Reynold number, the necessity for adopting high order scheme is emphasized when there is the complex flows with strong separation and high parameters gradient regions. Then, according to the entropy increased condition, the third order ENN scheme is constructed. Meanwhile, a fast, effective, and simple implicit numerical method called hybrid flux splitting method is developed. After that, the one dimensional model problem with many extrema and Burgers equation are simulated. Through the comparisons with exact solutions, the accuracy and effectiveness of the ENN scheme are confirmed.
