形容词 adj.
  1. Having the form of a line; straight or roughly straight; following a direct course.
    — The route taken does not have to be a perfectly straight line, just so long as it is linear and is followed consistently for each transect taken.
  2. Of or relating to lines.
  3. Made, or designed to be used, in a step-by-step, sequential manner.
    — a linear medium
  4. Long and narrow, with nearly parallel sides.
  5. (of polynomials or polynomial equations); Having degree one; that is, being of the form a_1x_1+a_2x_2+⋯+a_nx_n+b, where each x_i is a variable. See also Linear polynomials on Wikipedia.Wikipedia
    — 4x#43;5y#43;#92;frac#123;1#125;#123;2#125;z is a linear polynomial, but 4xy#43;#92;frac#123;1#125;#123;2#125;z and 4x#43;z² are not.
  6. (of polynomials or polynomial equations); Involving only linear polynomials. See also Linear equation on Wikipedia.Wikipedia
    — The graph of the linear equation y#61;ax#43;b is a straight line with slope a and y-intercept b
  7. (of functions or maps); An additive, homogeneous mapping; that is, a function f:V→W is linear if it distributes over vector addition (f( mathbf v+ mathbf w)=f( mathbf v)+f( mathbf w)) and respects scalar multiplication (f(c mathbf v)=cf( mathbf v)). If V and W are vector spaces over a field K, f may also be called a K-linear map. See also linear map on Wikipedia.Wikipedia
    — The map f#58;#92;mathbb#123;R#125;³#92;to#92;mathbb#123;R#125;² taking (x,y,z)#92;mapsto(x#43;y#43;z,x-y#43;3z) is a linear map.
  8. (of functions or maps); A module homomorphism; that is, a group homomorphism that commutes with scalar multiplication. See also Module homomorphism on Wikipedia.Wikipedia
  9. A type of length measurement involving only one spatial dimension (as opposed to area or volume).
    — a linear meter
  10. Delivered or delivering on a fixed schedule, as opposed to on-demand.
    — linear TV, linear content, linear video, linear radio
