稀疏

It is concluded that when a small solid angles range adjacent to the main direction in the far field is considered, the parallel beams combining of compact antenna arrays has its priority if the phases can be controlled, and the parallel beams combining of sparse antenna arrays has its priority if the phases can not be controlled.

分析表明：当关注的是远区主方向邻近的小立体角区域时，若能做到控相激励，宜采用紧凑阵的平行波束合成；若不能控相，宜采用稀疏阵的平行波束合成。

Base on comparison with the remote sensing data in 1982 and 2000 and field investigation, the results of land cover and land use change were obtained by the method of landscape analysis. Ten types of land use were identified: riparian woods, riparian shrubbery, desert shrubbery, desert grassland, river-way and water area, salinised land, town, Gobi, shift sand dune, denudative upland. The results show that,(1) there were obvious changes in land cover structure.

Image sparse representation via combined transforms means that an image is sparsely represented by overcomplete dictionary combined by several transforms.

组合变换图像稀疏表示通过几种变换的级联来构造超完备字典，实现图像的稀疏表示。

Overcomplete sparse representation can obtain the sparsest possible representation of the object and a resolution of sparse objects that is much higher-resolution than that possible with traditional non-adaptive approaches.

Inflorescence racemose or thyrsoid, on stems and old branches, 1.5-4 cm, densely grayish yellow to grayish brown pubescent.

偶数羽状的叶子，互生，25-40厘米叶柄；轴和叶柄淡灰黄色被绒毛；通常的小叶4 对，对生；小叶柄3-4毫米，密被绒毛；叶片正面深的绿色，长圆形或卵形长圆形， 13-30 * 5-11 厘米，纸质，沿着中脉和侧脉被绒毛的背面稀疏，正面沿着中脉的稀疏绒毛，花序总状或聚伞圆锥状的，在茎和老枝上生，1.5-4厘米，密被淡灰黄色到淡灰棕色短柔毛。

With selection, evaluation and the continuous self-pollination, two whole female parent lines were developed. Line A is green base fruit and hairless surface with few convexities, while line B with green base fruit and short thin thorn.

为此，我们于2000年从引进国外10品种，对此进行系统观察、鉴定、评价，通过连续自交的方式，纯化亲本，选育成A型果实基部绿色，果面有稀疏瘤突、无刺毛，B型果实基部绿色，果面有稀疏瘤突，且有短细刺毛的二个全雌性自交系亲本。

In this paper, in order to reduce algorithm's complexity we develop a novel method of obtaining very sparse representation of KDE exploiting Sparse Bayesian Regression technique with the assistance of regularization by jittering.

为了加快KDE的计算速度，简化模型的复杂度，提出了一种新型的基于稀疏贝叶斯回归的快速的KDE的计算模型，该模型用经过人工加噪处理过的分布函数逼近数据作为输入数据，获得了KDE的极为稀疏的表示。

In the framework of effective field theory, we have calculated the relation of Curie temperature and crystal field and discussed system's critical and related magnetic properties in the system of three-dimensional cubic lattice in the presence of bond dilution and random crystal field.

系统的居里温度随着晶场的增加而单调递减并且在相图中出现了三临界点，而键稀疏对三临界点有着明显的抑制作用，当键稀疏浓度降低到阈值pc 的时候系统将出现诱导磁有序，此时晶场浓度无论如何取值，该系统在一定的晶场范围内 0 ≤？

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""
