能在K线当中看出来什么?

可见光辐射一般指太阳辐射光谱中 0.78~0.4微米波谱段的辐射,由红、橙、黄、绿、蓝、靛、紫等七色光组成。是绿色植物进行光合作用所必须的和有效的太阳辐射能。到达地表面上的可见光辐射随大气浑浊度、太阳高度、云量和天气状况而变化。可见光辐射约占总辐射的45~50% [5] 。

可见光 应用

可见光 遥感技术

可见光 通信技术

可见光通信技术一种利用LED快速响应特性实现无线高速数据传输的新型绿色信息技术。将数字信号调制到电力线上,通过安装在LED灯内的通信模块,让可见光快速闪烁,以实现信息的传输。这种快速闪烁达到300 Mbit/s,人眼对这种闪烁是感觉不到的二在接收端通过感光器件接收这种闪烁的灯光,解调出来就是发射端想传输的信息。作为物联网技术之一的可见光通信技术,是在不影响正常照明的前提下,在有照明需求的场合可使照明设备具备“无线路由器”、“能在K线当中看出来什么? 通信基站”、“网络接入点”甚至“GPS卫星”的功能 [7] 。

可见光 云图

卫星观测仪器在可见光波段感应地面和云面对太阳光的反射,并把它显示成一张平面图象,即为可见光云图。图像的黑白程度是表示地面和云面的反照率大小,白色表示反照率大,黑色表示反照率小。一般说来,云愈厚,其亮度较亮。如果太阳光的照明条件一样,对同样厚的云来说,水滴云比冰晶云要亮。如大厚块的云,尤其是积雨云,为浓白色;中等厚度的云(卷层云、高层云、雾、层云、积云等)为白色;大陆上薄而小块的云区(如晴天积云)为灰白色等 能在K线当中看出来什么? [8] 。

可见光 可见光灯

3、荧光灯:一种阴极低压汞蒸气的放电灯,利用放电释放的紫外线,通过荧光粉的反射转换成可见光,使用双螺旋或三螺旋的钨制灯丝,在灯丝表面涂上电子发射材料,组成发射极。玻璃管内填充氩气、氪气、氖气的混合气,以及汞齐,玻管内壁涂三基色荧光粉。其工作原理:镇流器产生脉冲电压,使灯丝预热,阴极上的电子发射材料被激活,从而产生电子,电子与灯管内的汞原子碰撞产生253.7nm和185nm的紫外线,其中主峰值为253.7nm,约占全部辐射能的70%~80%;次峰值为185nm,约占全部辐射能的10%。紫外线透过涂有荧光粉的玻璃管内壁折射出可见光。因为使用了三基色荧光粉且有紫外光成分,荧光灯光谱有多个细小的尖峰波形,且有压力约为0. 8Pa的汞蒸汽,在电场作用下放电,汞原子的价电子从原始状态被激发成为激发态。同时,又以激发态自发地返回到基态,将价电子转化为电磁辐射能,并辐射出353.7nm的紫外线,其他还有10%左右的85nm高频紫外线。玻璃管内壁荧光粉吸收为353.7nm的紫外线,把它转化为可见光。由于荧光灯所消耗的电能大多用于产生紫外线因而荧光灯的发光效率远远高于白炽灯和卤钨灯,是较为节能的照明光源。荧光灯工作时灯丝的温度在1160K左右,比白炽灯工作的温度2400~2900K低很多,所以它的使用寿命也大大延长,达到5000h以上。荧光灯的另一特点是显色性好,对色彩丰富的物品及环境有比较理想的照明效果,光衰小,因此,被广泛地应用 [9] 。

Using Tkinter in Jupyter Notebook

Tkinter is a Python library used for creating and developing GUI-based applications. It is completely open-source which works on Windows, Mac, Linux, and Ubuntu. In Windows operating system, we can install the Tkinter library using the command pip install tkinter. It will install all the other modules that come with Tkinter library. Tkinter can be installed on Jupyter notebook as well, by using the command pip install tkinter. We can run all the standard commands of Tkinter in Jupyter notebook.

Once we have installed Tkinter in Jupyter notebook, then we can verify the installation by typing the following command −

Now, after verifying the 能在K线当中看出来什么? installation, you are ready to write your Tkinter application code in Jupyter notebook. For example, type the following code in Jupyter notebook and run the code by pressing "Shift + Enter".

Example

Output

Running the above code will display a window that contains a button widget.

In the given output, when we press the Enter key, it will show the Label widgets with some text.

WPS小技巧—WPS如何与EndNote关联

WPS如何与EndNote关联

WPS如何与EndNote关联

第一种情况,我们需要下载安装最新版的WPS Office 2019,以及安装EndNote到电脑本地。这个时候,打开WPS文档,会发现菜单栏里已经有了EndNote X9的标识,说明软件已经自动关联了。如图

操作路径:打开WPS文字文档 > 菜单栏 > 开发工具 > COM加载项 ,把EndNote.WordAddin.Connect选中,点击确定。

如果没有这个选项,点击添加,找到EndNote Cwyw.dll文件加载,这个文件默认位于C:\Program Files (x86)\Common Files\ResearchSoft\Cwyw\19\EndNote Cwyw.dll。

Using Tkinter in Jupyter Notebook

I have just started using Tkinter and trying to create a simple 能在K线当中看出来什么? pop-up box in python. I have copy pasted a simple code from a website:

This code is taking really long time to run, it has been almost 5 minutes! Is it not possible to just run this snippet? Can anybody tell me how to use Tkinter?

I am using jupyter notebook and python version 2.7. I would request a solution for this version only.

What is the problem? Your code is running fine for me. It immediately displays a form with two fields, as expected.

There is no error in the script. It works fine. Do you want to know how to run this snippet? Copy paste code to your editor, save it, (sample.py), run it using python3 sample.py in terminal. And do you want a pop up from tkinter master or just 2 text boxes in tkinter?

@sky_bird. You did not mention you used Jupyter in your question. I thought the problem was the python/tkinter.

Your code runs fine, the problem is Jupyter. Try to run this with a normal interpreter and see what it does.

@sky_bird, request you to copy paste your code to the bottom of all functions and let root.mainloop() be the last line of the file. It should work
