截面积

But when the earthquake actions are relatively large, the calculation of steel areas As and As' is often controlled by the design values of a group of forces which are obtained when the earthquake actions join in the combination.

但是当地震作用较大时，钢筋截面积As、As＇的计算往往是由一组有地震作用参与组合时的内力设计值

本发明还提供了一种喷射装置，它能够通过双层充电和电荷分离而向要喷出的组合物液滴施加单一极性的电荷，该喷射装置具有一个喷头，该喷头制成为致动器中的插入件的形式，喷头具有一个孔腔，液体能够通过该孔腔从装置中排出，该孔腔具有一出口，该出口最好具有曲线周边，并且L/a比率至少为8，其中L是以mm为单位的确定孔腔出口的周长，a是以mm2为单位的孔腔出口的横截面积，该装置构造成使得液滴在至少每秒0.5克的流动速率以及具有至少＋／－1×100C/kg的电荷／质量比的状态下从喷头排出。

Where A is the nozzle cross-sectional area, v is the velocity of the flow.

如果是喷嘴的截面积， V是速度的流动。

Where A p is the flow area of the grain and A t is the throat cross-sectional area.

如果一个P是流量辖区内的粮食和一吨是喉咙截面积。

To prevent debris into the pump, the pump inlet filter set, filter pipe cross-sectional area larger than 3 to 4 times.

为防止杂物进人泵内，泵进口处设过滤器，过滤面积大于管路截面积的3一4倍。

For the purpose of this requirement, a wire crossing the imaginary plane more than once is treated as separate wires and the cross-sectional area of a wire having a non-circular cross-section shall be taken as the cross-sectional area of a circular wire having a diameter equal to the maximum width of the wire having the non-circular cross-section.

为了达 到这一要求，电线不仅一次通过这个假想面。计算横截面积时，散线或非圆截面的电线的横截面积等同于圆线的最大直径横截面积。

Methods Twenty-three cases of OSAS patients proved by polysomnography were examined with MRI. The cross-sectional area of retropalatal region, retroglossal region, epiglottal region and the lateral parapharyngeal fat pad of RP region was calculated. The thickness of bilateral and posterior pharyngeal wall and other indices were also measured. 30 nonsnoring age-matched normal subjects were selected as the control group. 15 patients underwent turbo field echo T1-weighted imaging during sleep. The images of RP, RG, and EPG were analyzed. Results In oSAS group, the cross sectional area of RP and RG regions was smaller than that of the control group.

应用MRI对23例经多导睡眠监测（polysomnography， pSG）确诊的OSAS患者及30例无打鼾的健康成人进行上气道检查，于轴面图像测量软腭后区（retropalatal region， RP区）、舌根后区（retroglossal region， RG区）和会厌区（epiglottal region， EPG区）的气道截面积，各区前后、左右径及其比值，各区咽侧壁、咽后壁软组织厚度，RP区咽旁间隙（lateral parapharyngeal fat pad，LPFP）截面积，于正中矢状面图像测量软腭厚度、长度及截面积，对两组各项检查指标进行统计学分析。

Methods:①Make clinical scale of the magnitude of the tongue and the palate to the group of the OSAHS and the normal control②Successive scanning of the upper airway at the states of the normal inspiration and under the Müller action on both normal controls and the OSAHS patients with multi-slice spiral computed tomography. The scope of scanning was from the roof of nasopharynx to the level of hypohyal, bonding multiplate volume reconstruction,using the image workstation to survey the cross section area, sagittal diameter, coronal diameter on the soft tissue thickness in the lateral pharyngealwall and posterior wall of the pharynx, and the postzone of soft palate, uvula palatine ,tongue and epiglottis.

采用高分辨率多排CT(multi-slice spiral computed tomography，MSCT)对正常人和OSAHS患者的上呼吸道分别在平静吸气状态下以及Müller动作下进行连续扫描，扫描范围从鼻咽顶部至舌骨下缘，图象进行三维重建，应用图像工作站测量正常人和OSAHS患者的软腭后区(retropalatal region，RP)、悬雍垂后区(uvula region，UV)、舌后区(retroglossal region，RG)和会厌后区(epiglottal region，EPG)气道横截面积(cross section area，CSA)、矢状径、冠状径、咽侧壁和咽后壁软组织厚度以及舌体大小(包括舌体长度、舌体最宽处的宽度、中纵切面面积，舌背高度)。

The other 10 central lumbar disc herniation case s were chosen as control group with low back pain and sciatic nerve pain but cauda equina symptom.All 31 cases were treated by operation.Method of imaging analy sis:the CT foraminal and ruptured areas were measured by MAS-l computerized ima ging analysis system,then the rates of foraminal and ruptured area were calcula t ed.

图像分析方法：将CT断层扫描图像在MAS-1图像分析系统上作图像分析，在486计算机上分别计算出同一层面椎管和突出物的面积，再算出突出物所占同一层面椎管面积的百分率；结果显示31例疗效均满意。21例梗阻型平均随访1.5年，根性症状完全消失，肛门、会阴部症状3／4消失，1／4明显缓解，图像分析结果：21例有马尾神经受损表现者，其突出物占同一椎管截面积60.4%～75.8%，平均66.7%。

of imaging analy sis:the CT foraminal and ruptured areas were measured by MAS-l computerized ima ging analysis system,then the rates of foraminal and ruptured area were calcula t ed.Results showed that the nerve root pain disappeared in 21 obstructive disc cases besides the symptom of anus perineum disappeared in 3／4 and alleviated in 1／4 cases within 1.5 years follow-up.
