The experiment study about the subcritical normalizing holding temperature effects the macrostructure and hardness of the 40SiMnCrNiMoA steel shows: When subcritical normalizing holding temperature is 760℃, the ferrite in the mixture phase structure is lumpish, the hardness of the steel is low (about HRC32), and when the holding temperature is over 800℃, the hardness of the steel is about HRC49, the ferrite in the mixture phase structure is in old critical range austenite grain boundaries, it is disadvantage for the steel strengthening. When the holding temperature is 780℃, the mixture phase structure is mixture phase structure including the strip ferrite、martensite and bainite, the ferrite is less than 20%wt, its grains are fine and even, the hardness of the steel is about HRC38, it is in the range of HRC35-40 which is the long-life drill rod needed.
亚温正火温度对40SiMnCrNiMoA的组织和硬度等性能的影响的实验研究表明,当亚温正火保温温度为760℃时,复合组织中的铁素体形态是块状,处理后的材料硬度相对较低(HRC32左右);而当采用大于800℃温度亚温正火处理,材料硬度为HRC49左右,组织中铁素体大部分较连续地存在于原奥氏体的晶界,对材料强化不利;当40SiMnCrNiMoA钢780℃亚温正火后,硬度为HRC38左右,在以往小钎杆较长寿命所需硬度范围HRC35-40内,而组织为细条状铁素体+以板条马氏体和条状无碳贝氏体为主的复合组织,晶粒细小均匀,铁素体体积含量少于20%。

In this paper, the theory, algorithm, and experiment of automatic object detection and tracking are studied in depth. It is firstly pointed out that the essential of Mean Shift method is a special Newton-Gaussian method. A new method named Fast Mean Shift is established to stretch the conservative step of Mean Shift method. The convergence and validity of this new method are proved in theory. And it is also proved that the convergence speed of Fast Mean Shift is faster than that of Mean Shift. The contrast experiments of searching the maximum possibility density of random of data sets in plane and 3D space are done. The results show that this new method can reduce the iterations greatly. A new object tracking method based on Fast Mean Shift is built to improve the object tracking performance, which is shown in the face tracking experiment with the tennis sequence provided by the Ohio State University, and the car tracking experiment with the car sequence provided by Kalsruhe University. The face trcking experiment with highly noised images show that the object tracking method based on Fast Mean Shift has strong anti-jamming ability. A new fast color object detection technology based on characteristic color is established, which use characteristic color distribution to compute the characteristic color vector of any area in an image quickly. With the high performance search method, the fast object detection is achieved. At last, using object tracker based on Fast Mean Shift and color object detector based on characteristic color with the Kalman filter, PID controller, searial communication and other technologies, automatic object detection and tracking system with control system is built. The availability and anti-jamming ability of this system are verified by some object detection and tracking tests in different scenes.

The technology of electric information is developing very fast and make much more and more electric products teem,which develop in the direction of handy and miniaturization,such as mordern times communication equipmen、handy electric product、luggable computer、electric car、moonlet,and so on.it is used at large that the power supply make use of storage battery.hower most of storage battery can but use appropriative chargers,that need long time in the electrification and can't judge the electrification parameter and spare electrification time.thus it need a have much function and handy intelligent charger device that is a far-ranging application different kinds and types.the text integrate upwards request that will introduce a device and system of intelligent charger base on singlechip.in the power supply loop,the transformer take the voltage from 220v to 12v,then the rectifier circuit take the voltage turn to 14v,it is by way of the voltage of electrification power supply.
内容提要:电子信息技术的快速发展使得各种各样的电子产品不断涌现,并朝着便携和小型轻量化的趋势发展,现代通讯设备、便携式电子产品、笔记本电脑、电动汽车、小卫星等普遍使用蓄电池作为电源,应用非常广泛。然而大多数设备中的蓄电池,只能使用专用的充电器,而且普通的充电器大多充电时间长,无法判断其充电参数和剩余的充电时间,那么就需要一种广泛应用于不同种类和型号的可知道其充电参数和剩余充电时间的多功能便携式通用智能充电设备。本文结合以上要求介绍一种基于单片机的通用智能充电器的设计。

Nowadays, in the field of education, technology neutralism is a generally accepted theory of technology value, and "Technology is a two-edged sword" is a classical description of it. But it is a pity that the theoretical base of neutralism has been widely opposed in the field of philosophy, so it isn't dependable at all.
当前,在教育领域,技术中性论是人们广为接受的技术价值理论,"技术是一把双刃剑"是其观点的经典表述,但遗憾的是,中性论的理论基础已经遭到了来自哲学界的广泛质疑,其观点根本靠不住。
