| 1. | Solid state nuclear track dosemeter for personal neutron monitoring 个人中子监测用固态核径迹剂量计 |
| 2. | Programmable logic device is introduced into this design of neutron monitor device 在中子监测仪的设计过程中引入了可编程器件。 |
| 3. | However , neutron monitor device at present is not portable for working at outdoors 目前,国内虽有厂家生产,但设备过于笨重,不适合野外操作。 |
| 4. | For the need of monitoring the neutron generator , a kind of neutron monitor device is designed and developed , which is very suitable for our application and scientific searching 为此自行设计研发出了中子监测仪,很好地满足了科研和应用的需要。该中子监测仪引入了液晶显示器进行显示。 |
| 5. | In the design of neutron monitor device , a part of circuit is programmed into a chip , which improves the performance of neutron monitor device and reduces the area of pcb greatly 在中子监测仪的设计中,由于部分电路集成到同一个芯片内,使得中子监测仪工作性能大大提高,同时电路板的面积也大大减小。 |
| 6. | The working principles and characteristics of signal collection circuit , liquid - crystal display ( lcd ) , programmable logic device and mcu controlling circuit of neutron monitor device are discussed 论述了中子监测仪中的信号采集电路、液晶显示器的使用、可编程器件以及单片机控制电路的工作原理和特点。 |
| 7. | Neutron monitor device monitors whether the neutron generator is working in stable state , so that the workers on the spot can adjust neutron generator appropriately for working in order 中子监测仪用来监测中子发生器是否工作于稳定状态,以便现场的工作人员能够对中子发生器进行合适的调整,使其正常工作。 |
| 8. | Neutron monitor device uses mcu ( micro control unit ) as the control unit . mcu is the control center , and it controls lcd , programmable logic device , keyboard and communication with computer . it makes this system work harmony and fluently 单片机是系统的控制中枢,通过单片机来实现对系统的液晶显示器、可编程器件、键盘以及与计算机通讯的控制,使得整个系统能够协调、通畅的工作。 |
| 9. | This paper analyzed the data obtained at mcmurdo and thule neutron monitor ( nm ) stations and at guangzhou muon monitor station during the cme event in march 1991 . the results show that in this event when the cme structure passed the earth , it was shifted to the earth ' s southern hemisphere and the strongest magnetic structure associated with the cme passing the earth at about 2000ut , march 24 . 1991 我们利用mcmurdo和thule两个台站的银河宇宙线强度的观测数据和广州多方向介子探测器记录的宇宙线强度的数据分析了1991年3月cme的特征,注意到cme是一定程度地偏向地球的南半球,并给出了cme中最强的磁场结构到达磁层的时间为1991年3月24日2000ut左右,这是过去没有注意到的一个特征。 |
