作者： Xiaogang Wang yufei Zhao Xingchao lin China Institute of Water Resources and Hydropower Research Beijing100048China

Combining with empirical method, laboratory test and numerical simulation, a comprehensive system was presented to determine the mechanical parameters of jointed rock masses. The system has the following four functions: (1) Based on the field investigation of joints, the system can consider rock mass structures, by using network simulation technology. (2) Rock samples are conducted by numerical simulation with the input engineering mechanical parameters of rocks and joints obtained from laboratory tests. (3) The whole stress-strain curve of jointed rock masses under certain normal stress can be plotted from numerical simulation, and then the shear strength parameters of jointed rock masses can be obtained from the whole stress-strain curves under different normal stresses. (4) The statistical values of mechanical parameters of jointed rock masses can be determined according to numerical simulation. Based on the statistical values, combining with engineering experiences and geological investigations, the comprehensive mechanical parameters of jointed rock masses can be achieved finally. Several cases are presented to prove the engineering feasibility and suitability of this system.

分布式风电是一种新型风电,其优势在于充分利用用户周围的风能,降低输电成本同时提高供电可靠性。然而,由于靠近用户,分布式风场存在严重的噪声污染。以往的研究对噪声问题常采用降噪设备或者降低发电功率的方法处理,少有学者从优化风机布局的角度研究。对于分布式风场而言,布局优化十分关键且较复杂。因为分布式风场的经济性取决于布局设计,而布局设计又受风力波动、风机尾流损失以及电缆布线等复杂因素影响。因此,本研究结合噪声、风速分布、尾流损失、风机功率曲线以及缆线连接模型,以最大风场年经济效益为目标函数,采用遗传算法和斯坦纳树算法对风机位置分布和电缆布线进行优化,以期提高风场经济性的同时降低噪声影响。

Laser-based displays have attracted much attention owing to large-size screen and full-color gamut compared with other displays such as liquid crystal display and light emitting diode. However, there exists a phenomenon, speckle, limits the applications of laser display because of the high coherence of laser. In this work, we developed an electrically injected 6xx nm dual-emitter laser which combines the low-spatial coherence with the high-power. The output power of the dual-emitter laser exceeds 500 mW under 20?C pulse operation. The single emitter consists of D-shaped section used to obtain more independent spatial modes thus reduces coherence and a stripe area to obtain the high power. The radius of the D-shaped cavity is 500 μm and the length of stripe is 1000 μm. We used the standard photolithography and inductively coupled plasma (ICP) process to fabricate the device. The speckle contrast was measured to be 5%. It exhibits a great potential of reducing speckle from the source directly for laser display.
