The results showed that cotton swab and foam swab were the main oral care cleaning equipment used for oral intubated patients according to observations of ICU nurses performing oral care and self-reported questionnaires of ICU nurses. The cleaning solution was mainly dilute mouthwash. The mean correct rate was 72.4% in procedures of oral care. Due to the different characteristics of ICUs, the ICU nurses chose different cleaning equipment, cleaning solutions, methods of using cleaning solution, and oral endotracheal tube securement methods. Older age of the ICU nurses, was associated with more complete oral care. The completeness of performing oral care by the ICU nurses in medical ICU was significantly higher than that by nurses in surgical ICU.

研究结果发现，在实际观察护理人员执行口腔护理和护理人员自我报告口腔护理使用的清洁工具与溶液，口腔棉棒与海绵洁牙棒是气管内管留置病人口腔护理主要的清洁工具，清洁溶液主要选择以自来水或开水稀释的漱口水；口腔护理步骤平均得分百分比为74.2％；因护理人员所属加护病房性质不同，护理人员选择口腔护理之清洁工具、清洁溶液、清洁溶液使用方式及气管内管固定方式有所不同；护理人员年龄越年长，其执行口腔护理步骤完整率越高；内科系加护病房护理人员执行口腔护理步骤的完整性显著高於外科系加护病房护理人员。

Typical methods of the first class consist of predictive deconvolution, normal moveout interconversion stacking, f-k transformation, tau-p transformation, parabola Radon transformation and beamforming. They can be called as seismography method based on the geometry. The second class methods, mainly bases on elasticity undulatory theory, through simulation or reversal development method forecast multiple, and then match it with the original data.

比较典型的方法有预测反褶积、正常时差变换叠加、f-k变换、τ-p变换、抛物线 Radon 变换和聚束滤波等，它们可以简称为基于几何地震学方法或"几何滤波类方法"；第二类主要是基于弹性波动理论的方法，通过模拟或反演方法来预测原始数据中多次波，继而从原始数据中匹配减去所预测的多次波。

The traditional query tree optimization methods,parallel database optimization methods based on left linear trees and right linear trees,bushy trees,and operation of the forest,have their own pros and cons,they have been more in-depth and maturity of the study.The query optimization method based on multiple weighted tree has studied its model of parallel query plan,its complexity model of parallel query plan and query optimization algorithms.The semantic query method transforms an inquiry into one or several semantic equivalence inquiries then has to find and implement a strategy to achieve a better query.Agent-based parallel database query optimization using Multi-Agent technology to automatically search the integrity constraint conditions which are related to the determined query,there for,the efficiency between several relations' joins has been greatly improved.The parallel optimization algorithm,based on genetic algorithm which is suitable for multi-joins of cluster environment,has deeply studied the relations storage options,multi-joins query optimization and query processing and other key technologies based on cluster parallel database.
