I think the trailing function It is also very commonly used in many particle effects or spline animations, although it is not used very often. In fact, I also want to know whether this trailing motion blur is difficult to achieve at the software development level (this is just a personal curiosity about technology)

Motion blur on normal particles works fine in Octane; it's just this particular way you are creating them with the Tracer that doesn't blur. The C4D Tracer generator completely recreates elements afresh every single frame, so there is no motion in the resulting elements. In comparison, here is a shot of your scene with cubes assigned to the particles instead of a Tracer and they blur as you would expect. Be aware that the Octane Live Viewer doesn't always have all the information it needs to render proper motion blur for individual frames. To check that motion blur is behaving the way you want, it's best to render a couple frames in the Picture Viewer.

The curved path animation produced by the particles is a video effect that I occasionally use. But I can only use c4d's path tracing to identify these curved animation paths, but I can't give them dynamic blur. It is impossible to achieve a better picture effect.

No, the translation is doing a very good job! There's nothing at all offensive in your writing.
Since the C4D Tracer tool is specifically what you want, I think the option of turning the Tracer paths into geometry using Sweep and a small profile, then applying an opacity gradient texture to that Sweep geometry is your best bet; something like the attached screen grab. In this case I used luminance in a dark environment, but you could use standard diffuse color with an illuminated environment just as well. Keep both your Sweep profile sides and number of Sweep isoparm subdivisions low to prevent things from bogging down with large numbers of particles.
Good luck!
