小核

By using the least square method and the weighted functionmethod of nonparametric estimation together, this paper defines the wavelet estimators of β and g.

本文采用了半参数估计常用的办法之一——最小二乘法结合非参数权函数估计法定义了参数分量和非参数分量的估计，这里的权函数不是通常所采用的核权函数或近邻权函数，而是由小波方法所得到的权函数，我们称它为小波权函数。

But they were partial sterile, had 1～4 pollen sacs in each anther and had relative bigger petals and stamens at lower temperature situation. The RGCMS plants were complete sterile at the both temperature situations, and there was no pollen sac differentiation and had smaller peta...

表现核质不育的植株，在高温条件下，花瓣小，表现彻底的polCMS不育，无花粉囊的分化；在低温条件下，花瓣变大，也表现彻底雄性不育，具有核、质不育的共同特点，每个花药可分化出 1～ 4个花粉囊，但无可育花粉，其雄性败育时期和特点与S45A和 117A相同。

The DGCMS plants were complete sterile at the both temperature situations, and there was no pollen sac differentiation and had smaller petals and stamens at the higher temperature situation, but there were 1～4 pollen sacs in each anther and had bigger petals and stamens at the lower temperature situation. The cytological characteristics of the anther development were the same as that of GMS plants in Yi-3AB.

表现质核不育的植株，在高温条件下，花瓣小，表现彻底的pol CMS不育，无花粉囊的分化，在低温条件下，花瓣变大，也表现彻底雄性不育，具有核、质不育的共同特点，每个花药可分化出1～4个花粉囊，但无可育花粉，其雄性败育时期和特点与宜3A相同。

They were partial sterile, had 1～3 pollen sacs in each anther and had relative bigger petals and stamens at lower temperature situation. The DGCMS plants were complete sterile at the both temperature situations, and there was no pollen sac differentiation and had smaller petals and stamens ...

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。

The used SVM kernel function can not approach to any object function in regression.

针对目前使用的SVM核函数在回归中不能逼近任意目标函数的问题，在支持向量机的核方法和小波框架理论的基础上，提出了LS-WSVM结构模型。

According to the fine structures of reproducing kernels, the characterization of the image space in the wavelets transform and the isometric identities formulas are given by the perfect theory of reproducing kernel space.

An attractive hypothesis has been a semiconservative mechanism in which parental histones are combined with newly synthesized histones within the same core nucleosome.

一个有吸引力的假说是半保留的机制，在这一机制中，亲本的组蛋白和新合成的组蛋白共存于同一核小体核心中。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.
