| 1. | The common column in the set of tables built into a cluster . the cluster key must be indexed 一组聚簇表的共同的列。聚簇键必需要有索引。 |
| 2. | A study of performance optimization method for massive spaito - temporal data based on spatio - temporal partition clustering 基于时空分区聚簇的海量时空数据性能优化方法研究 |
| 3. | Thus , we also investigated the effects of elf - mf exposure on clustering of egf , tnf receptors in cultured cells 因此本文又进一步探索了极低频磁场对细胞膜受体聚簇的作用。 |
| 4. | The index on the cluster key . each cluster key must have an index before data can be entered into the cluster 聚簇索引:建在聚簇键上的索引。在数据存入聚簇表之前,聚簇键必要建立索引。 |
| 5. | A group of contiguous data blocks allocated for a table , index , or cluster . extents are added dynamically as needed 范围:分配给表,索引或者聚簇的一组连续的数据块。根据需求动态的增加“范围” 。 |
| 6. | Superposition of noise magnetic fields inhibits clustering of fibroblast membrane surface receptors induced by 50 hz magnetic fields in chinese hamster lungs 工频磁场诱导肺成纤维细胞膜受体聚簇及噪声磁场的干预作用 |
| 7. | For example , we have found the clustering of egfr ( epidermic growth factor receptor ) and tnfr ( tumor necrosis factor receptor ) and the activation of camp - pka - creb and jnk / sapk pathways after mnng treatment 例如细胞表面受体如表皮生长因子受体、肿瘤坏死因子受体发生聚簇,细胞信号转导通路camp kacgyb和jnk sapk被激活。 |
| 8. | In clustering part , we modify k - means for overcoming its trend limitation , making its clustering result more equal and mostly reflecting the character of clustering . the modified algorithm can increase the classification accuracy 聚类部分,改进了k - means算法,克服了它的倾向缺陷,使它的结果分布比较均匀,更能体现一个聚簇的规律,提高了分类精度。 |
| 9. | Dissimilarities are assessed base on the attribute values describing the objects . clustering processes are always carried out in the condition without pre - known knowledge , so the main task is to solve that how to get the clustering result in this premise 聚类分析依据的原则是使同一聚簇中的对象具有尽可能大的相似性,而不同聚簇中的对象具有尽可能大的相异性,聚类分析主要解决的问题是如何在没有先验知识的前提下,实现满足这种要求的聚簇的聚合。 |
| 10. | In order to confirm the effects of noise mf , in the present study , we use 0 . 4mt mf and noise mf , which intensity is hundred times than the previous studies and is proved repeatedly in our experiments to produce the clear biological effects , to examine the effects of noise mf on the clustering of egf , tnf receptors and sapk phosphorylation induced by 50hz mf 故本文使用上述经反复验证的、强度0 4mt 、具有明确生物效应的工频磁场及相同强度的噪声磁场,以sapk磷酸化及细胞膜egf与hf受体聚簇程度为研究指标,探索了噪声磁场及由噪声磁场与工频磁场叠加产生的复合磁场的生物效应。 |
