According to evaluation of the thermal, hydraulic, environmental and mechanic characteristics and energy performance of building and VAV air-conditioning system, and evaluation of the control performance of local control loops using the simulator of VAV system, this paper presents five on-line supervisory control strategies for local control loops: on-line optimization of VAV supply air static pressure set-point, on-line optimization of AHU supply air temperature set-point, on-line optimization of on/off set of CAV sub-system, on-line optimization of outdoor air set-point and on-line optimization of chilled water secondary pump pressure set-point.

通过数字仿真器对建筑物及其变风量空调系统的热力、动力、环境和能耗等运行特性的模拟，以及对系统常规采用的下位机控制回路可控性和稳定性等控制特性的研究和分析，本文先从局部的角度开展了系统局部优化的研究。提出并在仿真器上分别实施了VAV送风静压设定的实时优化，AHU送风温度设定的实时优化，CAV子系统开／停的实时优化，新风量设定的实时优化以及二级泵冷媒水供水压差设定的实时优化。

In chapter three, the new concepts of the bifurcation point and asymptotic bifurcation point of compact continuous operators in Menger PN-spaces are introduced. Some sufficient conditions for the existence of the bifurcation point and asymptotic bifurcation point are obtained. And the problems on the intrinsic value and intrinsic element of compact continuous operators are studied in Menger PN-spaces. A series of theorems on the existence of the intrinsic value and intrinsic element are obtained.

第三章，在概率赋范线性空间中提出非线性算子的歧点和渐近歧点的新概念，获得了非线性算子存在歧点和渐近歧点的充分条件；讨论了Menger概率赋范线性空间中非线性算子的固有值和固有元问题，得到了非线性算子存在固有值和固有元的一系列充分条件。

During 3D seismic data acquisition in Berri Block of Saudi Arabia,GPS navigation system was used while shooting,and monitoring shot-point drift on the interface of GPS navigation system,to initially control shot point error. Then,the method was applied to control seismic data acquisition quality,to analyze and examine shot-point drift and receiver-point drift.

在沙特Berri工区三维地震数据采集过程中，首先在放炮时采用GPS导航系统，在导航系统监控软件界面上监测炮点偏移情况，初步控制炮点误差；然后利用基于最小偏移距分选方法对地震数据采集质量进行监控，并对炮点和检波点偏移误差进行分析和检查。

Traditional photogrammetry was based on forward intersection and resection using survey point, so collinear equation （object point, image point and center of projection lie in a line） was the kernel of the whole photogrammetry, and relative orientation and absolute orientation were based on ideology of coplanar corresponding image point.

传统摄影测量是基于测点的前方交会和后方交会，所以共线方程（即物点、像点与摄影中心位于一条直线上）是整个摄影测量的核心。

In the study of the relation of the tangent and the tangent point of conics,this paper will introduce a solution to the problem in seeking the tangent and the tangent point of conics,with mapping the tangent into tangent point or mapping the tangent point into tangent using mapping correspondence.
