Activity of Diamine oxidase: DOA is the highly active endoenzyme in the microvilli of small intestine of human and other mammal, which activity has crucial correlation with nucleic acids and protein synthesize within mucous cells and also reflects the completion or trauma level of small intestinal mucosa.

二胺氧化酶活性：DAO是人类和哺乳动物小肠粘膜上层绒毛中具有高度活性的细胞内酶，其活性与粘膜细胞的核酸和蛋白合成密切相关，可反映小肠粘膜的完整性和损伤程度。

DOA identifiability issue for such arrays is discussed, and the corresponding Cramer-Rao Bound is derived also.

文中讨论了算法参数可辨识性的必要条件，并分析计算了多参数联合估计的克拉美-罗界。

The method transfers the observed data from space domain to 2-D space-time domain by exploiting the cross-correlation of the array outputs,and a large amount of virtual elements are generated through space-time processing.Therefore the constraint over the array configuration and the element identity can be significantly weakened,which means the matching subarray is no longer needed and the advantage of the traditional DOA matrix method,such as automatical parameter alignment and no need of 2-D search,is still available.

该方法在保持原DOA矩阵方法无需二维谱峰搜索和参数配对等优点的基础上，利用阵元输出之间的互相关关系将空域的阵列观测数据变换到时空域，通过空时二维处理在时空域中衍生出大量虚拟阵元，从而大大减弱了传统方法中对阵列结构、排布方式和阵元一致性的约束，不需要匹配子阵，无冗余阵元与孔径损失，并适用于阵元排列不规则的阵列。

This method can realize the separable estimation of DOA andangular spread for incoherently distributed source.

该方法可有效地实现非相干分布源波达方向和角度扩展的分离估计。
