对于定义域为[0,1]的函数f(x),如果同时满足一下三条:1.对任意的x∈[0,1],总有f(x)>=0;2.f(1)=1;3.若x1>=0,x2>=0,x1+x2<=1,都有f(x1+x2)>=f(x1)+(x2)成立,则称函数f(x)为理想函数。
这意味着在理想的情况下,您仅需要运行选择器一次,并且能够轻松地将所有函数连接在一起,或缓存结果供以后使用。
This means that under ideal situations, you might only need to run the selection once, with the ability to daisy-chain your functions together, or cache the results for future use.
而其内置的字符串操纵函数(包括正则表达式),以及程序上的特性和方便性使它成为创建简单“脚本”程序的理想语言。
And its built-in string manipulation functions (including regular expressions), as well as procedural and convenience features make it the ideal language for creating simple "scripting" programs.
理想情况下,这两个函数的使用应该限于对界面的拖放,因为这种情况下单击不会有合适的替代。
Ideally, the use of these two functions should be limited to dragging and dropping interfaces, where the click would not make a suitable replacement.
So that you could see that for the ideal gas, u would not be a function of volume, but only of temperature.
所以我们可以看到对理想气体,内能不依赖于体积,而仅仅是温度的函数。
So for an ideal gas, we saw that u was only a function of temperature.
对于理想气体,我们知道内能只是温度的函数。
Pressure has dropped out of the picture completely here. So there is no p dependence here.
理想气体的H只是温度的函数,这对于真实气体来说是。
