And so I could now make a plot x whereby I could have here x F and I could have here this force F, which I know because I know the masses.

现在我可以,画一张图,这里是,这是力，这个力我们知道,因为它就是重物质量。

youdao

Remember, partial f, partial x was obtained by y That means I am slicing the graph of f by a plane that is parallel to the x, z plane.

要记得，在这里的fx中,是作为常量保持不变的。，looking，at，the，situation，where，y，is，held，constant。,这是我用一个平行于xz坐标系的平面,横截了f，所得到的图形。

youdao

Well, the change in f is the value of f at the upper point here, which is x0+delta x, and minus its value at the lower point P, which is f of x0, divided by delta x.

f的变量就是f在上面的点时的值， x0+delta x，减去f在下面的点P时的值，x0，再除以delta x。

youdao

which is f , divided by the value of the x-axis here.

斜率，而f是p趋于0时pV的极限。

In addition, the revised deal gives the United States access to Japanese technology -- both that derived from transferred F-16 data and that arising from four FS-X development areas where the Japanese do not intend to -- or cannot -- obtain U.S. equipment or software.

CENTERFORSECURITYPOLICY: The FS-X Agreement

Independent Capability: Proponents contend that, given the fact that the Japanese have already designed the FS-X predecessor (the F-1) and have coproduced the F-4 and F-15 fighter aircraft with McDonnell-Douglas, the Japanese have an independent capability, with time, to design and produce the FS-X.

CENTERFORSECURITYPOLICY: The US-Japan FS-X Fighter Agreement: Assessing The Stakes

At the heart of the debate to date about the FS-X agreement have been various claims and counter-claims concerning the effect of the F-16 technology and manufacturing know-how the United States will supply Japan on the latter's competitive industrial position.
