酚类的羧化反应早期常采用固相直接羧化法，70年代国外逐步改用溶剂悬浮羧化法。

Technologies for determining methylation patterns in cancer cells, Methyl Light and COBRA, both of which were based on the deamination of methylated cytosines—which converts these cytosines to uracil residues—and identification of the converted sequence by analytical methods.

在上世纪80年代期间，研究的主要方法是PCR和克隆，两者都不涉及甲基化内容，因此很快就被弃用了。90年代，Laird开发了两类技术去检测肿瘤细胞中的甲基化模式，MethylLight和COBRA，两者都是以甲基化胞嘧啶的脱氨作用（将胞嘧啶转化为尿嘧啶残基）以及通过分析方法鉴定修改的序列为基础。

Firstly, Wavelet-Galerkin algorithm for solving the first kind of singular integral equation with the Hilbert kernel is proposed, we use the characteristic of periodic wavelet on L~2([0,1]) and Hilbert kernel to solve and make stiff matrix lower dimensions and become sparser through thresholding,thus the cost of computation is reduced. Because of the singularity of Hilbert kernel we use Tikhonov regularization method to solve the system of stiff equation. At last the convergence and numerical result of approximate solution are given. Secondly, an approach of regularization based on Fourier is presented for sideways heat equation; we give the theory proof and error estimate.

首先，提出了含Hilbert核的第一类奇异积分方程的小波伽辽金(Wavelet-Galerkin)数值算法，该算法中利用了L~2([0，1])上的周期小波和Hilbert核的特点进行处理，使得刚性矩阵维数降低并且通过阈值使得它更加稀疏，减少了计算量；由于Hilbert核的奇异性，通过Tikhonov正则化方法求解所得到的刚性方程组，给出了收敛性和数值结果；其次，对标准的一维逆热传导方程给出了一种基于Fourier正则化方法，给出了理论证明及其误差估计，解决了文献中算法与理论误差估计的不相匹配的现象，该正则化方法不仅保留了测量数据的部分高频成份，且与文献中的算法具有同样的计算量和误差估计。

There are two well-known shortcomings within K-Means algorithm prevailingly used in data clustering and other center-based clustering algorithms-the number of clusters must be known beforehand and the dependence of the algorithm performance on the initialization of the initial centers.

在聚类中广泛应用的K-Means算法及其它基于中心的聚类算法有两个共同的缺陷－需要预先确定类数目且随机初始化中心引起性能不稳定。

Alkylbenzene, normal alkanes and alkylcyclohexane on the pyrolysates of P. Boryanum at 300℃ had uniform distribution and the relative content of them was similar, indicating that they originated from same precursors. Fatty acids, alcohol and ketone in algal cell are the possible precursors. For example, the precursor of relatively abundant C〓 alkylbenzene and alkylbenzene with C〓 side chain perhaps related with palmitic acid. N-alkylnaphthalene in pyrolysates at 300℃ probably derived from alkylation of cleavage products of aromatic steranes and terpanes.
