All patients except one with clinical and radiologic findings suggestive of acute intestinal obstruction underwent single detector row CT of the abdomen and pelvis at the time of admission. One patient underwent CT 4 days after conservative treatment. Four patients with low-grade obstruction underwent enteroclysis, which is particularly helpful in depicting and grading the severity of partial obstruction and demonstrating sites of incomplete obstruction.

除1例病人外所有其他临床和影像学表现怀疑急性肠梗阻的病人在住院时均进行了腹部和盆腔的单排CT扫描，一例病人在经过保守治疗4天后进行了CT扫描；4例轻度梗阻的病人进行了肠道造影，这非常有助于对部分性肠梗阻进行描述和程度分级并显示不完全梗阻的位置。

Objective: Introduced evaporative light-scattering detector instrument structure, characteristic, principle of work, application and so on.

目的：介绍蒸发光散射检测器的仪器构造，特点，工作原理，应用等。

Automatic control commissioning: When detector sends alarming signal to the fire control center, the solenoid valve at the terminal exhauster and pre-active alarming valve unit is turned on and get the fire sprinkling pump started up.

自动方式调试：探测器报警信号传至消防控制中心，联动打开末端排气装置和预作用报警阀组上的电磁阀，并联动启动消防喷淋泵。

The application of CMOS image sensors ADCS-2121 is used in full automatic portable sun photometer to introduce the application of CMOS image sensors in pointing of optical system, and compared with traditional method that choosing quarter sensor as facular detector.

结合CMOS图像传感器ADCS-2121在全自动便携式太阳辐射计中的应用介绍了CMOS图像传感器在光学系统定位中的具体应用，并与传统的采用四象限探测器作为光斑探测器进行了比较。

In view of the facts that traditional graphical construction has less pertinence to stray light and tracing different incidence angle rays is fatiguesome and more likely to omit some rays, we proposed a reverse ray-trace method based on the ray reversibility. According to the method, a dot-matrix source was set at the image plane. Each dot emitted rays to fully cover the system aperture. A detector surface, large enough to receive all possible rays from the source, was set at object plane.

针对传统作图法设计遮光罩的针对性不强，且追迹不同入射角的光线繁琐、容易遗漏的问题，本文提出一种逆向追迹法，依据光的可逆性，在像面处设置点阵面光源，每一点都发出充满系统孔径的光束，在物面设置足够大的探测面，使之有充足的余量记录所有到达物方的光线，利用该方法可以在探测面上直观地区分出非成像杂散光。

This one mode pays close attention to network credence foundation of the businessman very much.
