DB48X：重新设计的高性能科学计算器

Url: http://48calc.org/

很抱歉，但作为一个AI，我无法直接访问外部网站或执行网络抓取任务。因此，我无法使用JinaReader或其他工具从提供的链接（http://48calc.org/）抓取内容。

如果您需要分析某个网站的内容，并希望将其翻译成中文，以下是一般的步骤：

1. **抓取内容**：使用网络爬虫或抓取工具（如Scrapy、BeautifulSoup等）从网站上抓取HTML内容。

2. **翻译内容**：抓取到的内容可能包含多种语言。如果需要将非中文内容翻译成中文，可以使用在线翻译服务API，如Google Translate API、Microsoft Translator Text API等。

3. **总结内容**：翻译后的内容可以由人工或使用自然语言处理工具进行总结。

以下是一个使用Python编写的示例代码，演示如何使用Google Translate API翻译网页内容：

```python
from googletrans import Translator, LANGUAGES

# 创建翻译器对象
translator = Translator()

# 网页URL
url = "http://48calc.org/"

# 发送HTTP请求获取网页内容
import requests
response = requests.get(url)

# 确保请求成功
if response.status_code == 200:
    # 翻译网页内容
    translated_content = translator.translate(response.text, src='auto', dest='zh-cn')
    
    # 打印翻译后的内容
    print(translated_content.text)
else:
    print("无法获取网页内容")

请注意，上述代码需要安装requests和googletrans库，并且Google Translate API需要有效的API密钥。

如果您需要进一步的帮助来处理特定的网站或内容，请提供更多信息。

**jwr**: The 48G was a really good calculator, but only after loading additional software. The HP50g that came much later is better in every respect, except possibly for the smaller &quot;ENTER&quot; key (and people used to 48G will have to change some habits and possibly redefine some keys…).<p>Incidentally, many young people (yes, I know how that sounds) do not know how useful a good engineering calculator can be and do not want to learn how to use one. They are missing out. Yes, there is a steep learning curve, but the rewards are significant if you do any amount of calculation in your hobby or work. No, this is not replaced by typing &quot;python&quot; (or &quot;bc&quot;, or anything else, really) at your command prompt.<p>Also incidentally, the development of good engineering calculators pretty much died. HP Prime is largely a school-pleasing toy, HP would down their calculator division a long time ago, and nobody else produces anything good. It&#x27;s kind of like with gyms: what you get is what the market wants, and since the market doesn&#x27;t know much, you get gyms full of useless exercise machines, because that&#x27;s what people think a good gym should have. Similarly with calculators: you get stupid &quot;modern&quot; graphing calculators which are useless for actual work (it takes forever to use them to calculate useful things, and graphing is much better done on a computer), but they look great and sell well.<p>I admire the project, although I would probably have taken a different path (emulation) to get the biggest effect with the smallest possible effort :-)<p>I wish there was a good HP50G emulator for iOS — there used to be one, but it was abandoned (contact me if you want to develop it and would like to get the source code, it was under the GPL and I got it from the author).
> **jwr**: 48G是一个非常好的计算器，但只有在加载了额外的软件之后。后来推出的HP50g在各方面都更好，除了可能更小的&quot；输入“；键（习惯了48G的人将不得不改变一些习惯，并可能重新定义一些键……）<p> 顺便说一句，许多年轻人（是的，我知道这听起来如何）不知道一个好的工程计算器有多有用，也不想学习如何使用它。他们错过了。是的，学习曲线很陡，但如果你在业余爱好或工作中做任何计算，回报都是巨大的；python“；（或者“bc”，或者其他任何东西，真的）在命令提示符下<p> 顺便说一句，好的工程计算器的发展几乎已经消亡。HP Prime在很大程度上是一个讨学校喜欢的玩具，惠普很久以前就会关闭他们的计算器部门，而且没有其他公司生产任何好产品。它；这有点像健身房：你得到的是市场想要的，既然市场没有；我不知道太多，健身房里到处都是无用的健身器材，因为；这就是人们认为一个好的健身房应该有的。计算器也是如此：你会变得愚蠢&quot；现代”；图形计算器对实际工作毫无用处（使用它们计算有用的东西需要很长时间，在计算机上绘制图形要好得多），但它们看起来很棒，卖得很好<p> 我很欣赏这个项目，尽管我可能会采取不同的方式（模拟）以最小的努力获得最大的效果：-）<p>我希望有一个很好的iOS HP50G模拟器——曾经有一个，但它被放弃了（如果你想开发它并想获得源代码，请联系我，它是在GPL下的，我是从作者那里得到的）。
            
**Ringz**: I still have a HP48GX in perfect condition and love it. One of my first programs was to calculate how much „slower“ my time is running when I drive a car or fly in a plane compared to someone standing still on the sidewalk.<p>I still find it much more comfortable having a real calculator… call me old fashioned.
> **Ringz**: 我仍然有一台状况良好的HP48GX，我很喜欢它。我的第一个程序之一是计算我开车或坐飞机时的时间比站在人行道上静止的人慢多少。<p>我仍然觉得有一个真正的计算器要舒服得多…叫我老派。
            
**PaulHoule**: I am a fan of the HP Prime<p><a href="https:&#x2F;&#x2F;hpcalcs.com&#x2F;product&#x2F;hp-prime-graphing-calculator&#x2F;" rel="nofollow">https:&#x2F;&#x2F;hpcalcs.com&#x2F;product&#x2F;hp-prime-graphing-calculator&#x2F;</a><p>But I use it in algebraic instead of RPN mode.  I’ve got a 49g and a 50-something too.<p>People say it is pricey but I managed to get one discounted that was intended for the Latin American market.  So is the thing that software is supposed to run on.

**tooltechgeek**: The Casio fx-9750GIII though very poorly named is a gem full of functionality from python, to spreadsheet and even a text editor and very low priced for what it does. If HP made a similar product with RPN it would be a game changer.
> **tooltechgeek**: 卡西欧fx-9750GIII虽然名字很差，但它是一款功能齐全的宝石，从python到电子表格，甚至是文本编辑器，而且价格非常低。如果惠普用RPN制造类似的产品，那将改变游戏规则。
            
**SomeHacker44**: Spectacular project by one gentleman. Been using it for a while now on my Swissmicros.
