Based on a series of signal process and noise source identification techniques, especially the major noise source identification methods, such as expurgation method, sound intensity analysis, spectrum analysis vibro-acoustic correlation analysis and so on, the pass-by noise control of SC7080A and SC6360B are studied in detail. By the roadway and dais experiments, the major noise and radiating parts are identified and some economical controlling methods are made. For the SC7080A, to control the emissing noise from the intake and shell vibration of air cleaner, a intake muffler is installed between the air cleaner and intake valve. Based on the theory of Helmholtz resonator, One three-parallel-connected resonant silencer is designed and trial-manufactured. For the SC6360B, the attenuation performance of exhaust muffler in high frequency region is improved. To reduce the vibration noise of shell part, the structure of oil sump tank, exhaust manifold shield and exhaust manifold shield are analyzed and improved. At the same time, some measures, such as sound absorption, sound insulation, are taken to reduce the noise of engine surface emissivity and a sound shield is designed.

本文首先综述了目前国内外汽车加速噪声控制的现状、主要方法和技术措施，在此基础上，结合SC7080A和SC6350B汽车的车外加速噪声水平及现状，综合运用分别运行法、声强法、频谱分析法、声振相干函数法等现代噪声源识别方法，对SC7080A和SC6360B汽车进行了准确详细的车外加速噪声源识别并提出了经济可行的控制方案，针对SC7080A，主要在空气滤清器和进气阀门之间的进气管道上加装进气消声器，抑制空气滤清器壳体表面和进气口两处的噪声辐射，根据Helmholtz共振腔原理设计了三腔并联旁支型共振消声器，并进行了工程化设计和试制；针对SC6360B，主要改善了排气消声器在高频段的消声性能，对罩壳类零件进行了结构改进，降低了其表面噪声的辐射，并对发动机舱进行了吸声、隔声处理，设计了发动机隔声罩。

However time for body temperature recovery, anal exsufflation time and discharge time had no significantly differences between two groups.

在术后体温恢复正常时间、肛门排气和平均住院时间方面差异无统计学意义。

If the container curvature is too large, such as a circular cylinder, pressure-sensitive labels in the zaimo, exsufflation, that should not be used in-mold labels.

如果容器曲率过大，如圆形瓶，在模内贴标过程中，排气有困难，那就不应该采用模内标签。

Die design structure, during the production process shape produce products, deformation, pluckup, exsufflation malformations bubbles in the process of pressure-sensitive labels.

模具设计结构不合理，在生产过程中易造成产品形状变化，变形，鼓起、排气不良导致贴标过程中出现气泡。

The effect of pain-alleviating,exsufflation,postpartum hemorrhage,lactation was compared.

观察两组术后镇痛效果，肛门排气时间，产后出血，产妇泌乳情况。

Results The recovery time of bowel sound was 8-112 h (M=28 h) in the treated group and 16-24 h (M=46 h) in the control group, with a significant difference P=(0.0001. The time of anal exsufflation in the treated group was 2-116 h (M=56 h), and 24-147 h (M=82 h) in the control group, with a significant difference (P=0.0001). The electroenterogram revealed that control activity, continuous response activity and contractive electrical complex were significantly stronger in the treated group than in the control group.

结果 187例经观察(治疗组93例，对照组94例)，肠鸣恢复时间治疗组为8～112h，中位时间为28 h，对照组为16～124 h，中位时间46 h，有显著统计学意义(P=0.0001)；肛门排气时间治疗组为22～116 h，中位时间56 h，对照组为24～147 h，中位时间82 h，有显著统计学意义(P=0.0001)；肠电图显示治疗组各检测肠段的电控制活动、连续反应电活动波、收缩电综合波均显著增强。

To accelerate the early recover of exsufflation in patients with abdominal operation, patients were encouraged and helped to do some activities early. They were observed on their recover of exsufflation when they did activities in different time.

腹部手术病人因麻醉、手术创伤、牵拉等刺激，加之腹腔开放、热量的散发，常导致胃肠功能紊乱，主要表现为肠蠕动消失，术后排气、排便功能障碍，直接影响病人的预后。

The following data were compared respectively between two groups ,such as operation time, exploratory rate of other diseases in peritoneum,time of post-operative anal exsufflation and ambulation,operation expense,the amount of analgesics patients need after operation,the incidence of incision infection,adhesive intestinal obstruction and residual infection in abdominal cavity.

回顾分析360例经腹腔镜输卵管绝育术和同期360例开腹输卵管结扎术的手术资料，比较两组手术时间、腹腔内其他病变探查率、术后肛门排气时间、术后下床时间、手术费用、术后止痛剂使用、切口感染、粘连性肠梗阻、腹腔残余感染发生率等指标。

The nursing plan of improved postoperative nursing for experimental group is that puerperas were given fluid diet at postoperation 6 hours instead of 24 hours,removed catheter at postoperation 6 to 12 hours instead of 36 to 48 hours and encouraged and helped ambulatory early . Then the times of anal exsufflation and first leaving bed and breast milk secretion were recorded,autonomous urination and postoperative complications were monitored . These results were compared with those of control group,which was adopt ordinary abdominal longitudinal straight incision for cesarean section of lower uterine segment .

对研究组术后护理进行了改进，将术后24小时进流质饮食改为术后6小时进流质饮食，观察肛门排气时间；将术后36至48小时拔除导尿管的时间改为术后6至12小时，观察产妇自行排尿的情况；鼓励并协助产妇早期活动，记录首次下床活动时间，泌乳时间和术后并发症的情况，与200例常规腹部纵形直切口子宫下端剖宫产对照。

The surgical duration ranged from 35 to 170 min ［mean=（92.3±25.6） min］; amount of blood loss during operation was 50-700 ml ［mean=（120.0±36.3） ml］. The earliest time of anal exsufflation was 9 h after operation and the last was 27 h. The postoperative morbidity was 12.6%. The hospital stay ranged from 5 d to 9 d ［mean=（7.2±1.6） d］.
