Methods Fifteen pigs were anaesthetized, and trachea intubation and transfemoral cannula were performed then. Swan-Ganz catheters were inserted to pulmonary artery via internal jugular vein, and aeroperitoneum was set up by airing CO2. These pigs were randomly divided into three groups (5 pigs in each group) according to different levels of IAP （IAP10, IAP20, IAP30）. Hemodynamics and oxygen metabolism values were observed and recorded before airing, 6, 12, 18 and 24 hours after airing, respectively.

15只猪经麻醉后，行气管插管、股动脉插管及经颈内静脉肺动脉插管，CO2充气建立气腹，根据随机数字表法将猪分为IAP 10 cm H2O组(IAP10组)、IAP20组及IAP30组（每组5只），记录充气前，充气后6、12、18及24 h的血流动力学和氧代谢指标，观察不同水平IAP在不同时点上对血流动力学及氧代谢的影响。

By analyzing the results of LSNR measurements for samples with different components, and comparing with the media of Aprilis Corporation, we give the suggestion to optimize the material components in the future. In addition, based on the physical mechanism of intra-page crosstalk noise, we proposed the Pixel-Matched Spread Function, and a simplified deconvolution arithmetic to suppress the intra-page crosstalk noise.

另外，在分析数字数据全息存储中页内串扰噪声产生的物理过程的基础上，提出了像元匹配扩散函数的概念，并提出了一个反卷积算法来抑制页内串扰噪声，计算机模拟和实验结果都证明我们提出的PMSF算法可以有效的抑制页内串扰噪声，提高恢复数据页的保真度。
