新型三级变速电动轮毂的研制

针对现有电动车不能适应复杂路况和动力轮转矩不够大的问题,通过在原有电动轮毂上加装机械变速箱来实现轮毂的三级变速,使新型轮毂获得更好的路况适应能力,并且可以根据需要换挡获得更快的速度或更大的转矩。本产品将机械变速箱集成在电动轮毂内,减小了新型三级变速电动轮毂的体积;单向飞轮的使用省去了离合器的使用,使变速过程变得简单易行,新型三级变速电动轮毂的动力性能得到了提高。     

浅谈高职软件专业C语言的教学方法

根据高职软件专业C语言教学中普遍存在的问题,如学生学习的积极性不高、编程思维欠缺、上机练习比较盲目等,本文结合教学和实际中运用C语言的一些体会对教学方法提出了一些建议,以更好地促进C语言教学。     

曲线渐近线类型的拓广

在现行中等、高等数学教材中曲线的渐近线通常仅限于直线型渐近线,对此本文用发散性思维,对曲线的渐近线的范围进行拓广,给出曲线的曲渐近线的概念,并由此得到几种曲渐近线。     

论高校日语听力互动教学课堂的开展

耐热木聚糖酶源细菌筛选、鉴定及酶学性质

利用木聚糖作为唯一碳源的基础盐培养,在50℃培养条件下,从新乡周围土样及腐殖质中筛选到1株产耐热β-木聚糖酶细菌,初步鉴定为巨大芽孢杆菌（Bacillus megaterium FLH-2）.该菌株在40~55℃生长良好,最适生长温度50℃.木聚糖酶粗酶性质研究表明：该酶最适pH和最适温度分别为6.0和65℃;在pH 5.0~9.0及温度30~75℃之间酶活相对稳定,分别处理30 min,相对酶活仍保持在80%以上.     

Real-time temperature control for high arch dam based on decision support system

It is important and difficult to control the temperature of mass concrete structure during high arch dam construction.A new method with decision support system is presented for temperature control and crack prevention.It is a database system with functions of data storage,information inquiry,data analysis,early warning and resource sharing.Monitoring information during construction can be digitized via this system,and the intelligent analysis and dynamic control of concrete temperature can be conducted.This method has been applied in the construction of the Dagangshan Arch Dam in China and has proven to be very convenient.Based on the decision support of this system and the dynamic adjustment of construction measures,the concrete temperature of this project is well-controlled.     

CFD simulation of micro-particle trapping under water tweezers

In early research, capture and manipulation of particles were mainly achieved by means of light, electricity and plasma in micro-fabficaton and micro-assembly. A new method is proposed using micro-water jet to form water tweezers to capture solid particles and implement position control of micro-particles. This paper analyzes the basic prin- ciple of water tweezers, and the discrete element method and smoothed particle hydrodynamics method are employed to establish a solid-liquid coupling model used in analyzing the trapping mechanism. A flow field model is set up to simulate dynamic characteristic of water tweezers based on computa- tional fluid dynamics （CFD）. Selection of boundary conditions, initial guess, solver control and convergence strategies of the model are discussed. Velocity and pressure of streamline are predicted and discussed under certain input conditions. Simu- lation results demonstrate that it is an efficiently theoretical method to eventually trap solid particles by water tweezers.     

民国时期目录著作新编出版研究

民国时期编制的目录著作的数量,应不低于1500种。2000年后,文献整理机构及学者收集整理并汇编出版了20余种大型影印文献,收录的原版目录著作超过700种。文章对新版文献的出版概况进行了详细梳理,总结出版现状和问题,提出相应的对策,并分析出版趋势,以期对民国时期目录著作的进一步出版整理有所裨益。
