Optical coherence tomography (OCT) is a new imaging modality that provides cross -sectional tomographs of ocular structure in vivo. OCT system utilizes propagation of light through, and the time - of - flight delay of light reflected back from biological tissue to produce false - color images of microstructure. OCT has superior spatial resolution (10μm) than other optical imaging instruments, and maybe achieved at arbitrary penetration depth in transparent tissue with a noncontact, noninvasive measurement....

Optical coherence tomography (OCT) is a new imaging modality that provides cross -sectional tomographs of ocular structure in vivo. OCT system utilizes propagation of light through, and the time - of - flight delay of light reflected back from biological tissue to produce false - color images of microstructure. OCT has superior spatial resolution (10μm) than other optical imaging instruments, and maybe achieved at arbitrary penetration depth in transparent tissue with a noncontact, noninvasive measurement. Such features make OCT useful for the early diagnosis, differential diagnosis and more sensitive monitoring of a variety of ocular abnormalities including glaucoma, retinal and anterior eye diseases. Eye Science 1998:14 ; 116 - 120.

光学相干断层成像术(OCT)是近几年始用于临床的新型影象诊断技术。与超声成像等技术不同,它利用光波在生物组织的传播特性并检测反射光的时程延迟,构成组织横断面图象,以观察其微细结构并进行定量分析,纵向分辨力可高达10μm,并具有非接触性、非侵害性等特点。在眼科,它不仅能够对眼前节的结构进行成像,还可以对视网膜各层次结构进行清晰的显像,为多种眼内疾病、特别是青光眼的早期诊断和研究提供了一种新的有效途径。眼科学报1998;14:116—120。

The air\|hold and the ground\|delay time of the flight are an effectiveness index to evaluate the Air Navigation System. Up to now its calculating method is Monte\|Carlo statistical method generally. But longer time of the computation is the limitation of this method. In this paper, the flight and control procedure and the airspace structure of the airport terminal area are analyzed particularly by using the stochastic serve system theory, an operation model is established, and the calculating formula is educed finally. So the problem about the fast calculating method of flight delay is resolved successfully.

In this paper,the queue methodology has been used to establish the area traffic flow control model (ATFCM). The actual effects of area flow control made by Zhengzhou area control center have been simulated by ATFCM. The achievement show that the current area flow control method used by controllers will enhance flight delay among all related areas. Finally, the paper points out that all related areas reasonably selecting the time division and time separation should be considered to produce less flight...
