By using testing functions to make comparative research on the precision of approximate models which were built by RBF under the condition of different sample amounts and different kernel function types, a conclusion was drawn: the model quality built by Reciprocal Multiquadric RBF as kernel function was highest when the sample amout was big, and the model quality built by Gaussian RBF as kernel function was highest when the sample amount was small.

运用测试函数对在不同样本数量与不同核函数形式下所建立的近似模型的精度进行对比研究，得出逆多二次函数与高斯函数作为核函数分别在大样本和小样本情况下精度最高的结论，并验证了径向基函数近似模型方法能够兼顾效率与精度。

将27个核桃居群坚果的9个性状进行巢式方差分析，结果表明居群间和居群内差异均达极显著(P＜0.01)，说明其居群间和居群内存在广泛的变异。

By extending the incremental singular value decompositionto the kernel space,the kernel formulation of incremental kernel PCA,which possessed much lower computational complexity and was suitable for online model updating,was obtained.

RKPCA算法通过将递归奇异值分解推广到核空间，给出了核形式描述的递归KPCA算法，运算复杂度比KPCA明显降低，保证非线性监控模型能够在线更新。

Sinceβkernel is non-symmetric, there will be problem in the precision of graduation if using kernel graduation method, because, generally, kernel function is supposed to be symmetric in kernel graduation method, thus will cause boundary deviation in actual application.

但β核为非对称核，如果使用核修匀方法，在修匀精度上仍会存在问题，因为一般核修匀方法中均假设核函数具有对称性，在实际应用中将导致出现边界偏差现象。

Symmetric kernel graduation ; non-symmetric kernel graduation ; Gamma kernel ; boundary bias

对称核修匀；非对称核修匀； Gamma核；边界偏差

Scanning electron micrograph results showed no surface rupture either on garlic skin or garlic kernel by sodium alginate solutions. It also indicated tubular texture for the surface of garlic skin, and sponge-like structure for the surface of garlic kernel, respectively. Average surface roughness by magnetic force microscopy were under 57 for garlic skin, and under 13 for garlic kernel, respectively.

扫描式电子显微镜影像观察可知海藻酸钠薄膜溶液涂布后皆不会对蒜皮或蒜仁表面造成破坏，并且发现蒜皮表面较为粗糙之维管组织，相对於蒜仁表面较平滑之海绵薄壁组织。

This paper first discusses the nature of the kernel function,and then based on Riemannian geometry dependent on the data structure and method,an improved modifying kernel function is proposed,the kernel function is a simple and less calculation method,which conformal factor and support vector irrelevant,compared with previous studies overcomes the impact of support vector's number and distribution.

首先讨论核函数的本质，并且基于黎曼几何结构和数据依赖的方法，提出了一种改进的修正核函数，改进后的核函数形式简单，计算量较低，其中保形因子与支持向量无关，较之于以前的研究克服了支持向量的数目和分布的影响。

This chapter proposes three conceptions, i.e., Kernelled quasidiferential, star-kernel and star-diferential, and establishes their operational properties. A sufficient theorem and a sufficent and necessity theorem for a quasi-kernel being a kernelled quasidiferential are proven. Both the existence of star-kernel for a quasidiferentiable function and the existence of star-differential for a direnction-ally diferentiable function are established.

在这一章里，首先给出核拟微分，星核与星微分的定义及其它们的运算性质；然后证明了拟核微分的一个充分条件定理及一个充要条件定理；最后讨(来源：A27BC论文网www.abclunwen.com)论拟可微函数星核的存在性及方向可微函数星微分的存在性以及Penot-微分与上下导数之间的关系。

All teachings in the great-vehicle Buddhism and its sutras regard the personal realization of Tathagatagarbha as the kernel; the personal realization of the two-vehicle Buddhism, according to the historic facts in The Four Agama Sutras, has the central thought of believing in the permanent existence of Tathagatagarbha so that the state of the remainderless nirvana becomes real, permanent and unchangeable, and does not fall into the nihilistic state. It is not just us who claim Tathagatagarbha as the kernel of Buddhism; it has been so since the very beginning when Buddha established Buddhism.

因此，大乘佛教及经典中的种种所说，都是以如来藏的实证为核心；二乘佛教的实证，依四阿含所显示的史实，则是以相信有如来藏常住不灭，使无余涅槃成为真实、常住不变，而不落入断灭境界，作为中心思想；并不是只有我们有此主张，而是佛教从释迦牟尼佛创教以来就一直都是以如来藏为核心，初转法轮时就已经如是，故在《阿含经》中仍然处处记载著这样的实例，平实已在《阿含正义》共七辑书中明确的举证《阿含经》中是如何一再开示这个正理了；此外，不仅止北传的大乘佛教与四大部阿含如此记载，南传的小乘佛教经典也是如此记载，才会有爱阿赖耶、乐阿赖耶、欣阿赖耶、喜阿赖耶、穷生死蕴等记载。
