来到瑞芳镇水湳洞的「黄金瀑布」,这座位在公路旁背倚无耳茶壶山的层叠瀑布,因含有丰富的黄铁矿与硫砷铜矿,让地表呈金黄色,也是形成阴阳海的主要水源,当奔腾的瀑水流泄而下时就像是一座堆满金矿的瀑布般,耀眼动人,一幕清澈的水帘直冲金黄色的地表让人一时兴起玩水念头,不过由於这里的水质含有大量重金属物质,为了自身安全,还是三思而后行,黄金瀑布位於本山六坑口下方的自强桥畔及长仁矿区,因为早期在上游采铜矿,山泉水与雨水渗入,矿砂沉积溪床,又有菌类附着滋生、地势落差较大所以形成金黄色的瀑布奇观,黄金瀑布是金瓜石当地很有特色的一个景点,平时也很容易遇到来此地拍摄婚纱的新人。

Through the knowledge of the urban societies, this case study puts the New Caoya Urban Squatter Settlements back in the Story of the urbanization and the housing policy, discuss its historic and social formation, breaks the public opinion's prejudice, puts in light the ill-assorted sharing of the country resources and the unequal development of the cities.At the same time, this research introduces the formation and the structure of the New Caoya Urban Squatter Settlements - it comes at first from the urban development bringing a need of workers, the population migrates massively from the countryside to the city, the study shows more clearly the bad regulation of the housing policy. In the time, the authorities, to relieve the tension of the consumption, let the Squatter Settlements form. With the evolution of the urbanization, it became a choice of extra housing. Today the New Caoya Squatter Settlements play still an important role among the low incomes families.

ABSTRACT Aiming at problems of trans-vector controller in a vehicle-carried induction motor such as variable rotor and stator resistance following motor temperature, and their inductance varying with flux saturation degrees. Firstly, CSI and VSI are introduced, for CSI, it can hold the advantages both FOC and DTC using stator flux directional, PI parameter and simulation are also introduced. Secondly, equations of IM in the synchronous rotary frame and its static counterpart, as figuring in the saturation condition of magnetic field, are dealt in this paper and the simulation results are presented. Thereafter, the parameter designing of PI trans-vector controller is processed, which features the non-linear model. In practical realization, as neglecting the dynamical change of motor inductance, this paper employs online modification of inductance parameters, according to the flux saturation, then transforms the non-linear equations into linear ones, and so compacts the structure of controller. Thirdly, in view of the maximum torque output is extraordinary requisite when Electrical Vehicle start up, accelerate, and overtake, this paper issues the maximum torque when both inverter and battery capacity is corporeally definite. Fourthly, on-line differentiating and analyzing both rotor's time constants and its flux by using the expanding order reduction and discrete Kalman filter equation are fathomed, in order to realize high-performance trans-vector algorithm, and also the simulation results are presented. Fifthly, the close-loop regenerative brake system, when the EV's torque is set constant, is deduced; at the same time, unification of electric drive model and brake model is executed. Combined with maximum charge current demands, the mathematical model for online yielding torque as a demand.
