在随机信息系统中，根据不可辨识关系，提出了不可辨识属性矩阵的概念，证明了不可辨识属性矩阵与可辨识属性矩阵的关系，最后提出了一种基于不可辨识属性矩阵约简算法。

We study the express of heparinase,matrix metalloproteinase MMP-2,MMP-14 and cadherin in the gastric cancer tissue and perigastric normal mucosal tissue,and make a statistics analysis between heparinase, matrix metalloproteinase MMP-2,MMP-14,E-cadherin and gastric cancer biological behavior.We hope to knom the possibility that heparinase,matrix metalloproteinase MMP-2,MMP-14,E-cadherin are regared as clinical screen index of the gastric cancer recrudescence or metastasis.

本文就肝素酶、基质金属蛋白酶MMP-2、MMP-14、钙粘蛋白在胃癌组织及胃周正常粘膜的表达进行了研究，并就肝素酶、基质金属蛋白酶MMP-2、MMP-14、钙粘蛋白与胃癌的生物学行为进行了统计学分析，以期了解肝素酶、基质金属蛋白酶MMP-2、MMP-14、钙粘蛋白作为胃癌复发或转移的临床筛选指标的可能性。

Before the primary data matrices are multiplied, each is treated for noise by multiplication by a perturber where E= is the original primary matrix, is the perturbed matrix, and is the perturber matrix.

以前的原始数据矩阵都是成倍增长，每次治疗是噪音的乘法的一个perturber其中E=是原来小矩阵是摄矩阵，且是perturber矩阵。

Moreover, the matrix effect was investigated. The results showed that samples could be completely decomposed by melting in lithium tetraborate and lithium carbonate mixed flux at about 1000℃. The introduction of lots of lithium and matrix magnesium in solution affected the determination, which could be corrected by matrix matching. Calcium, iron and aluminium with high content had no spectral interference with other elements with low content.

结果表明，样品用四硼酸锂和碳酸锂混合熔剂在1000℃左右的温度下熔融，可以完全分解试样；引进试液中大量锂和基体铁时测定有影响，用基体匹配的方法克服，含量较高的钙、铁和铝对含量低的其他元素没有光谱干扰。

Based on the electric models for shaly sands and tuffaceous sands, this text derived modelsof saturation bored with water for the tuffaceous sands: Tuffaceous sand S-B Model andEffective Medium HB Model;The first supposed that the parts of shaly sands and thetuffaceous part were electric parallelly, and the other considered the electric rock matrix as sandmatrix, tuffaceous matrix and shaly matrix were parallel, and ignored the difference betweenwater bounded with shaly sand and water in the formation.

基于泥质砂岩的导电模型并结合凝灰质砂岩骨架导电的特点，建立凝灰质砂岩含水饱和度导电模型：凝灰质砂岩 S-B 模型和有效介质 HB 电阻率模型；前者假设凝灰质部分与泥质砂岩部分并联导电，而后者将凝灰质砂岩骨架导电看成砂岩骨架颗粒、凝灰质颗粒和泥质颗粒的并联导电，并忽略粘土结合水与地层水导电性的差异。

Moreover, using the in vilro DNA-matrix binding assay results showed that HS2, HS3 and HS4 core DNA sequences were unable to bind to the nuclear matrix isolated from uninduced HEL cells; in addition, HS2 core DNA sequence was capable of binding to the nuclear matrix prepared from Hu-induced HEL cells, while both HS3 and HS4 can not bind to it.

同时，运用核基质与DNA体外结合实验表明，这些核心DNA序列均不能与非诱导的HEL细胞内的核基质结合。
