The paper analyses the law of services spatial diffusion in chongqing city, which is the law of business services spatial diffusion base on contagious diffusion hierarchical diffusion and base on the law of stochastic diffusion along the axes, and, according these principle, revise the unit factors score of business services calculated by using traditional way
由於重慶市地形復雜，江河阻隔，因此山城城市職能除表現為傳染擴散規律外，更突出地表現為等級擴散和軸向隨機擴散規律。文章依據這些原理對採用傳統的方法得到的商服功能影響作用分進行修正，同時探討了結點數動態變化時城市職能的空間擴散規律。On the base of above it, this paper discuss the synthesis of optimum distributed arrays by nonuniform spacing in the sense of dolph - chebyshev. having derived the equations of optimum element distribution, we analyze the exponentially spaced array, which are optimum when the elements are isotropic and equally weighted, and the array by general raised cosine function. the formulate for estimating the sidelobe envelope, beamwidth of the array pattern and clean region width are obtained
推導了最佳陣元分佈方程，分別對陣元無方向性和等加權時的最佳分散式陣列? ?指數間隔陣列和採用廣義升餘弦加權的最佳分散式陣列進行了分析，推導了天線方向圖旁瓣包絡、波束寬度，干凈掃描區寬度的估計公式，給出了近軸旁瓣電平與陣列參數的關系。A switchable and spacing - tunable dual - wavelength linear cavity edfl is demonstrated experimentally using this kind of bragg grating for wavelength selection. it exploits the birefringence characteristic of the fbg induced by transverse strain. transverse strain loading on the fbg allows the wavelength spacing to be controlled while axial strain shifts both wavelengths together
2 .對軸向及側向應力共同作用下的光纖布拉格光柵的透射及反射光譜特性進行了理論及實驗研究，並首次把軸向及側向應力共同作用下的光纖光柵應用於光纖激光器進行波長選擇，得到了室溫下穩定工作的波長及波長間隔可調的可開關雙波長的摻鉺光纖激光器。Thereby measures for improvement are put forward : ( 1 ) adopting a small wheel to replace the steel ball of the ball type unit to ensure more reliable motion of the creeping device ; ( 2 ) applying expansible metallic ring replacing the step - by - step teeth on tooth type unit ; ( 3 ) fixing a sensor in the reversing device for obtaining the information of motion and wear of the creeping device
為此，提出改進措施： 1 .對球型步進式清蠟器採用帶穿軸的小輪代替鋼球，可使爬行器運動更可靠； 2 .對齒型步進式清蠟器，採用可脹緊金屬環代替步進齒，金屬環依靠抽油機的沖程力脹大后使爬行器固定，反沖程力使金屬環縮小； 3 .將傳感器裝在換向器內，根據信號的時間間隔判斷爬行器的運行速度及磨損等情況。Rolling bearings ; angular contact radial ball bearing ; double row, with spacer balls
