常見例句雙語(yǔ)例句So the idea of spherical coordinate is you're going to polar coordinates again in the rz plane.所以說(shuō)球坐標(biāo)系,其實(shí)就是在rz平面再建立一個(gè)極坐標(biāo)。In this paper, the general solution for plane problem of elastic mechanics in polar coordinate system is deduced by separate variable method.用分離變量法推導(dǎo)出極坐標(biāo)彈性力學(xué)平面問(wèn)題的一般解，給出了問(wèn)題的解答全貌，為解決各種具體問(wèn)題提供了理論基礎(chǔ)。And cylindrical coordinates only mean that we are, instead of x, y and z, y we are replacing x and y by the polar coordinate in the x, y plane, r so the angle theta and the distance r.柱坐標(biāo)系就是，用平面上的極坐標(biāo)替換x和，即角θ和距離。 返回 polar coordinate plane
