The authors used a database of Medicare beneficiaries aged 65 years and older to identify individuals who were cancer-free and who had undergone at least one colonoscopy or sigmoidoscopy between 1991 and 1998, and they then calculated the incidence and risk of perforation within seven days of the procedure.During 39,286 colonoscopies, there were 77 perforations, or 1.96 perforations per 1,000 procedures, compared with 31 perforations during 35,298 sigmoidoscopies, or 0.88 perforations per 1,000 procedures.

结果显示，在39，286位做大肠镜筛检的民众之中，有77位发生肠穿孔。35，298 位做直肠镜筛检的民众，有31位发生肠穿孔，也就是说，做大肠镜筛检者，每1，000位就有1.96位可能发生肠穿孔，而直肠镜筛检的肠穿孔发生率则为每1，000位中有0.88位。

Since there were 10 more unscreened cancer patients and 5 more cervical cancer deaths in the cytology arm than in the HPV arm and since these unscreened cancer patients predictably had higher rates of cervical cancer, more advanced stages, and less favorable outcomes, the net effect of the inclusion of the larger number of unscreened cervical cancer patients in the cytology arm was to make the cytology arm appear more like the unscreened control arm of the study.

由于在细胞学组中有10个未筛查的宫颈癌病人和5个宫颈癌死亡者，高于 HPV 组，同时因这些未筛查的宫颈癌病人预期有较高的宫颈癌发生率，更加进展的临床分期和较差的预后，因而大量未筛查的宫颈癌病人在细胞学组中，这样结果的净效应是细胞学组更像本研究中未筛查对照组。

This machine is the patent product of our country, which use machinery method to form its screen by special screen piece juxtaposed on the rotor and rotor rotates at the same direction speed, so the coal on the screen can circumrotate resort to peach type screen and move forward with fluctuate form so as to come to the purpose of high efficient sieve classification.

Objective:to probe the application on the hearing screening of the neonatus by transcience otoacoustic emission.methods: to undertakethe hearing screening of the neonatus by transcience otoacoustic emission of 2 100 neonatus from 2006.1~2006.12.results: 2 058 (98.4%) full-term newborn infants pass the transience otoacoustic emission once and 33(1.6%) full-term newborn infants can not pass it once.9(77.8%) premature infants pass the transience otoacoustic emission once and 2 premature infants can not pass it once.conclusion: the transience otoacoustic emission is worth to application because it has non-wound, fast, objective merit.

目的：探讨观察瞬态耳声发射在新生儿听力筛查中的应用。方法：对2006年1月~2006年12月2 100例新生儿利用瞬态耳声发射进行听力筛查的资料进行分析。结果：2 091例足月新生儿中，一次通过瞬态耳声发射进行听力筛查 2 058例，占98.4%，未通过33例，占1.6%，早产儿9例中，一次通过检测7例，占77.8%，未通过2例，占22.2%。全部未通过新生儿检查abr，确诊有异常15例，正常7例。结论：瞬态耳声发射具有无创伤、快速、客观、敏感度高等优点，值得在新生儿听力筛查中广泛推广应用。

This method can make sure the structure radiant sound status in total noise and the detail phonate part quickly and correctly.(3) Study on the control mechanism of structure noise radiated from rotary machines, we build a common model of rotary machine structure noise analysis relied on the general characters of rotary machines. Based on this model, we analyzed various influence factors to structure radiant noise using the union of revolution and numerical calculation method. We found that the joint stiffness between the rotor and the frame is the most sensitive parameter of structure radiant noise by calculating and analyzing.

根据本文对于旋转机械结构噪声控制技术的研究结果和惯性振动筛工作的特殊要求，对有关参数的选择进行了讨论，并通过试验为降低惯性振动筛噪声找到了两个新的方法：即，在轴间相对运动要求不高的情况下，可以在激振器与筛体之间安装一组减振器，通过适当选取减振器参数，既可以使机体在工作频率附近获得稳定振幅，保证振动筛正常工作，又可以使机体的高频响应减小，降噪效果显著；反之，如果轴间相对运动精度要求(来源：1aABC论文网www.abclunwen.com)较高，可以采用空心滚动体轴承，在保证滚动体强度的条件下也可以获得较好的降噪效果。
