The controller receives, analyzes and processes the command input by operator via the man-machine interface, to adjust and control the controllable light signal generator according to the analysis processing result and the spectrum result checked by the light checker, the controller outputs the adjustment and result via the man-machine interface to the operator, to output light signal for the result of adjustment and control on the controllable light signal generator, via the light coupler to be coupled partly and feedback to the light checker to be checked, thereby forming a closed-circuit, while the light signal coupled to the light output via the light coupler reaches user target spectrum demand.

本发明公开了一种实现光信噪比可调节的光信号源装置及控制方法，所述装置包括：控制器、人机接口、可控光信号发生器、光耦合器、光信号检测器、光信号输出口；控制器接收操作者输入给人机接口的指令并分析和处理，运用分析处理结果、并结合光检测器检测的光谱结果数据来调节和控制可控光信号发生器，控制器将调节过程和调节结果通过人机接口输出给操作者，对可控光信号发生器调节和控制的结果输出光信号通过光耦合器耦合一部分又反馈给光检测器检测，这样形成一个闭环控制，使得通过光耦合器耦合到光输出口的光信号达到用户目标光谱要求。

On the base of the advanced theories, research methods from home and abroad, intensive use of urban land on the connotation and extension have been defined, also the driving factors of intensive use land in Xinjiang have been analyzed. As the case of nineteen cities of the Xinjiang Uygur Autonomous Region, from the land input level, the extent of land use, land-use efficiency and land use in four areas of eco-environmental quality, the establishment of a level of intensive use of urban land evaluation system has been done in this ***. Using the methods of Principal component analysis, Spearman rank correlation coefficient and ArcGIS, calculate the principal city of the intensive use of urban land points between 2001-2006, the municipalities of urban Land Use Composite Index, build the three-dimensional display model of Intensive use level of urban land, then analyses the characteristics of spatial-temporal variance of the urban land intensively utilization. Finally, analysis propose measures and advices.

本文反在呼取海外外相闭实际和研讨方式的基本上，闭于城市土地集约当用的外涵及外延入行了界订，并闭于旧疆土地集约当用的驱动果荤入行了剖析，然后以旧疆19个从要城市为研讨区域，自土地投入火平、土地当用火平、土地当用效力和土地当用生态环境量量四个方里，树立了城市土地集约当用火平评价指本体解，采取从败开剖析法闭于旧疆2001—2006暮年城市土地集约当用火平入行了评价，盘算各从要市的城市土地集约当用得开，用秩相闭解数闭于所盘算出的各市的城市土地集约当用综开得开入行时光特征剖析；还帮ArcGIS软件，剖析旧疆城市土地集约当用火平的空间格局；自城市非工业己口、投入、产出取用地删加弹性三个方里剖析城市土地分体集约当用收铺趋背；最初降出了土地集约当用的闭于策建议。

The Middle Hymalaya Movement is the main stage of reverse faults--migration channels and traps development, and also in this stage the Leikoupo Formation petroleum system formed. The advantageous structural traps lie in low steep and low gentle structures in the broad--gentle synclines or in the north and south plunging areas of the high steep structural belts.

喜山中期运动是本区油气运移通道--断层以及圈闭发育的主要时期，也是雷口坡组成气系统形成的主要时期；其有利圈闭多发育于高陡构造带中宽缓向斜内部或高陡构造带南北两侧倾没消失部位的低陡和低缓构造。

Results indicated that under the conditionwhen there is lack of water in the soil, deep ploughing will lead to dec-rease yeild before sowing, deep ploughing will aggravate the dispellingof the soil water when the field is fallow in the summer.
