Methods A nested RT-PCR was used for detecting one fragment of SARS-CoV RNA in oropharyngeal swabs from 3 SARS probable patients ,4 SARS suspect patients and other 27 patients with fever in Hangzhou, and the nested RT-PCR product from one SARS probable patient was sequenced.Meanwhile in these 3 SARS probable patients, other three RT-PCR methods, including a hemi -nested RT-PCR targeted for another fragment of SARS-CoV RNA, a real-time RT -PCR and a modified nested real-time RT-PCR, were employed to detect SARS-Co V RNA.Results Two positives were found in the 3 SARS pro bable patients, and none positive in 4 SARS suspect patients and other 27 patien ts with fever, using the nested RT-PCR.

For example: Oracle may choose an index fast full scan instead of an index range scan because the compressed index is now much smaller, and your setting for parameter db_file_multiblock_read_count is large; or Oracle may choose to use an index and do a nested loop because the index is now 30% smaller, where previously it was doing a table scan and hash join.

由于压缩索引现在更小了，对参数db_file_multiblock_read_count也较大，那么Oracle可能选择一个index fast full scan而不是index range scan；或者由于索引减小了30%，Oracle选择使用一个索引和nested loop，而之前它用表扫描和hash join。

For the thrashing due to true sharing of data, we thoroughly study the relationship between array element accesses and loop indices of a nested loop, present a complete set of ideas, theories, and methods with which the staggering relation and the compacting relation between the threads of the nested loop (either with a single linear function or with multiple linear functions) can be determined at compile-time, and accordingly the nested loop (either perfectly nested or imperfectly nested) can be restructured to avoid the thrashing problem.

使用这套理论和方法，我们在编译时就可以确定出嵌套循环（含单线性函数或多线性函数，紧嵌套或非紧嵌套）各线索间的错位关系，一致错位关系和压缩关系，根据这种关系对嵌套循环进行重构可以使真共享抖动问题得到很好的解决。
