[Objective] The paper was to explore the herbicidal activity of 41% flufenacet SC and its safety to soybean, wheat and maize. [Method]The herbicidal activity of 41% flufenacet SC on four species of weeds and its safety to three crops were determined by indoor bioactivity assay.[Result] 41% Flufenacet SC had good control effects against Amaranthus retroflexus, Descurainia Sophia, Bromus japonicus and Echinochloa crusgalli, with the ED90 of 154.1, 204.9, 273.1 and 140.9（a.i.） g/hm2, respectively. [Conclusion] The selectivity index of 41% flufenacet SC between the three crops tested and the two species of weeds was 6.63-9.24. The agent had good safety to soybean, wheat and maize.

Optoelectronic Date Acquisition System Based on FPGA

国防光电子论坛第二届新型探测技术及其应用研讨会

作者： Xin LI Chunyang LIU De song zhiguo TONG Xiangqing LIU School of Science Changchun University of Science and Technology

An optoelectronic date acquisition system is designed based on FPGA. FPGA chip that is EP1C3T144C8 of Cyclone devices from Altera corporation is used as the centre of logic control, XTP2046 chip is used as A/D converter,host computer that communicates with the date acquisition system through RS-232 serial communication interface are used as display device and photo resistance is used as photo sensor. We use Verilog HDL to write logic control code about FPGA. It is proved that timing sequence is correct through the simulation of Model Sim. Test results indicate that this system meets the design requirement, has fast response and stable operation by actual hardware circuit test.

作者： Yujia song Xijun Liu zhiguo Zhang Yao Xiao Pengde Liu

As one of the principal constituents of continental crust, some granitoids retain messages from the perceived crust–mantle interaction, which can be used as tracers of the geodynamic evolution and the continental growth process of orogens. However, the source and evolutionary trends of granitoids are still highly controversial. For example,

The Central Asian Orogenic Belt(CAOB), is the largest proliferative orogenic belt in the phanerozoic, located between Siberia and the Tarim north China plate. Its tectonic evolution is closely related to the evolution of the ancient Asian Ocean. The CAOB has an intimate connection with the evolution of Paleo-Asian Ocean(PAO) which experienced geodynamic processes like seamounts accretion, ridge-trench interaction,

由于知识产权在高科技产业中的重要地位,使得高科技产业的发展对知识产权的有效保护具有高度的依赖性。在知识产权保护的各种手段中最强有力的措施当然首推知识产权法律制度,但是,由于知识产权法自身的特别规定性和知识产权权利实现的特殊性困难,知识产权法律保护的有效性受到了一定限制。要实现知识产权的有效保护,必须克制对知识产权法律制度等外部因素的过分苛求,将注意力集中到高科技产业系统内部的自我保护问题上来,使知识产权的有效保护逐步通过一种内生性增长来实现。

基于电压源换流器和脉宽调制控制的柔性直流输电是一种新一代的高压直流输电技术,应用前景广阔。继上海南汇风电场柔性直流接入示范工程后,根据规划,2014年大连电网将投运世界上首个百万千瓦级柔性直流输电工程。为保障工程顺利实施,需详细分析大容量柔性直流接入对电网的影响。文中首先在国内广泛使用的电力系统机电暂态仿真程序中,开发了柔性直流输电系统模型与算法,并通过与电磁暂态计算的对比,验证了模型与算法的正确性。针对柔性直流接入后大连电网典型运行方式,研究了送受端交流电网故障以及直流控制方式和控制参数等对混联电网恢复特性的影响。研究结论为混联电网和交直流设备的安全稳定运行提供了技术支撑。
