Results Body mass index,family history,and hypertension history were found to be OSAS-related risk factors,OR=1.502,8.511 and 5.497.Conclusion Body mass index,family history,and hypertension history are all the risk factors for OSAS,so the incurrence of OSAS can be lowered down by instruction of keeping fit,controlling body weight and keeping on diet,proper exercises,active control of blood pressure,changing the bad living habit and quitting drinking and smoking so that their life quality is improved.

笔者对OSAS的疾病相关危险因素进行分析，为降低该疾病的发生率，减轻患者疾病相关症状，改善防治措施提供依据。1对象与方法1.1研究对象选取2007年4-7月在广州市呼吸疾病研究所睡眠中心和珠江医院呼吸科睡眠室接受全夜多导睡眠监测(polysomnography，PSG)的患者为研究对象，入选的标准为年龄≥18岁，本人知情同意。

It uses Index Block of 91 x 2 Matrix to store record and index pointers.

What the above shows is that in an index of 1 million sequential entries, the vast majority have the same leading byte and so will all be trying to get into the same block in the index.

上面所示的是在一个一百万序列项的索引中，绝大多数有一个相同的前导字节，从而所有将使用索引中的同一块。

What the above shows is that in an index of1 million sequential entries, the vast majority have the same leading byte and so will all be trying to get into the same block in the index.

However, rather than always being stored in the same single 'hot' index block, new entries will be spread across a number of existing blocks (assuming the index has been around for a while) thus reducing contention.

但是，与总是存储到同一个"热"块中不同，新的项目将分摊到多个已有的块（假定索引已运作了一段时间）中。

Prefix entries are available for sharing immediately after being written to the index block and remain available until the last deleted referencing suffix entry is cleaned out of the index block.

Then, the index corresponding to the closest codevector is transmitted to the decoder. Due to the spatial correlation of an image block, the VQ index for a block is highly related to those of its adjacent blocks. If we can remove the kind of redundancy, the bitrate required for coding the VQ indexes can be reduced.

由於影像方块间具有空间相关联性，因此每个方块的索引值与其邻近四周方块的索引值间存在极高的相关联性，假如我们能移除这些关联性累赘，则编码向量量化索引值所需的位元率将可大为减少。

If the application is multi-user then it means that every user will tend to write into the same index block and buffer busy waits will be the outcome as transactions 'queue' to write data to the hottest index block around.

若单用户执行应用程序，这不是什么问题。若应用是多用户的，则意味着每个用户将写入同一个索引块。
