"Although the risk of bowel perforation is often cited as a major factor in the choice between colonoscopy and sigmoidoscopy for colorectal screening, good estimates of the absolute and relative risks of perforation are lacking," write Nicolle M.

利用Medicare的资料库找出1991 ~ 1998年间，65岁以上、未罹患癌症且至少接受过一次以上大肠镜检或直肠镜筛检的健保民众，根据这份资料算出这些民众在做完筛检后7天内发生肠穿孔的机会。

Thetemperature cruises the examintion instrument is a refrigerator to examine a part of the system automatically, this lesson an intelligence for is a kind ofly with 8051 single a machines for core constituting instrument system, that temperature cruises the examintion instrument cans cruise to return to examination to 64:00 temperature proceeding with show that can examine to a certain proceeding fixed-point again with show, at examine at the same time to can proceed the sound and light report to the police, taking a string of a communication connects the oscular temperature cruises the examintion instrument .

温度巡检仪是冰箱自动检测系统的一部分，本课题是一种以 8051 单片机为核心构成的智能仪器系统，该温度巡检仪可对64点温度进行巡回检测和显示又可对某点进行定点检测和显示，在检测的同时可以进行声光报警，带有串行通讯接口的温度巡检仪。

The emulation result shows that the error of polarizer rotation angle almost does not influence nonlinearity when elliptic polarization of laser beams exists; when the error of rotation angle of polarizing beam splitter exists, the second-harmonic nonlinearity caused by the error of polarizer rotation angle will not increase, but the first-harmonic nonlinearity will increase greatly.

仿真结果表明，当存在激光束椭圆偏振时，检偏器旋转误差对非线性误差的影响很小；当存在偏振分光镜旋转误差时，检偏器旋转误差引起的非线性误差不增加二次谐波分量，但增大了非线性误差一次谐波分量，严重影响非线性误差的大小，当偏振分光镜旋转误差为3°时，检偏器旋转误差从0°增加到5°，非线性误差从0.14 nm增大到0.97 nm。

Objective To study the diagnostic value of pulmonary carcinoma via fibrobronchoscope brush biopsy, protractor biopsy and sputum cytology.

The teaching term took sixteen periods. The curriculum contained two topics,"acid and base", and "Taiwan's climate". Experimental treatments were teaching method. The research tools utilized in the study were " Science Concept Comprehension Test, Science-related Attitudes Scale, Problem Solving Ability Test and Questionnaire on the Attitude toward Science Teaching". A pretest administered before the experimental treatment and a posttest was held after the treatment. The data of SCCT, SRAS, and PSAT collected from pretest and posttest were analyzed by two-way ANOVA. Responses from the QAST were analyzed by ANOVA.

本研究的实验处理为以问题为中心的合作学习教学，研究工具包括「科学概念理解问卷」、「科学相关态度量表」、「问题解决测验」、「对自然科的教学态度问卷」、「教学检核量表」及「问题中心教学自我评估量表」，分析「科学概念理解问卷」、「科学相关态度量表」和「问题解决测验」资料时，以前测经验和教学法为自变项，后测为依变项，进行二因子变异数分析；「对自然科的教学态度问卷」采用单因子变异数分析；「教学检核量表」及「问题中心教学自我评估量表」则用来检核研究者的教学是否符合研究者的研究设计；在质性资料的部分，则分析学生的上课纪录、教师教学反省纪录及对自然科教学的态度问卷的理由。

Results: Relative diagnostic accordance rate of the clinical exploration and four kinds of image processing setup was the highest（P＞0.01）in the first premolars. Relative diagnostic accordance rate of the clinical exploration and the pseudocolor image setup and negative image setup was the highest（P＞0.01）, and that of the clinical exploration and the pseudo3D image setup and positive image setup was the lowest（P＜ 0.01）, showing statistical differences in the second premolars.

结果：①第一前磨牙：4种图像处理格局下邻面龋的检出结果与临床诊断结果的符合率高，差异无统计学意义（P＞0.01）；②第二前磨牙：负片和伪彩图像格局下邻面龋的检出结果与临床诊断结果的符合率高，差异无统计学意义（P＞0.01）；③正片和伪3D图像格局检出结果和临床诊断结果的符合率低（P＜0.01）。

First, the optical principles and functional designs of current schematic eye for retinoscopy were briefly introduced.
