The main objective of this dissertation was to develop methodologies with capability of engineering application for simulating flow in fractured rock using discontinuum models. The study work includes three parts. In the first part, numerical methodology of three-dimensional discrete fracture network model casing on hybrid BEM-channel was presented, and the technique for improve the model's computing efficiency was also studied. Firstly in this part, computer simulation methodology based on the Baechermodel for generating network of discrete fractures was presented, which includes the follow details: probability distributions of fracture density,orientation, trace length, size, and aperture and estimation of their statistical parameters; stochastic models of fracture network; Monte-Carlo's simulation method; numerical simulation procedure and technicality.

The Periscope Drawtube will be bent because of the water resistance in sailing and this bend will cause the error of star measurement. Due to its especial structure, contactless measurement is the only way to measure its bend degree. First this paper introduces the method by linear array CCD based on structure and light path; Second it expatiates linear array CCD work principle and driving scheduling with example of TCD1501C and the driving circuit by CPLD. The output signal of linear array CCD includes common disturbance so the differential amplifier is needed. In order to make the signal adapt to computer processing, a threshold circuit with Schmitt characteristic and the data process following threshold are given. At last, some key problems in application are given.
