...the only thing comparable is the ion temperature (best temperature achieved is about 50 times that in the core of the sun), but density is really really low. We are talking near vacuum here.
Also, "为了探索和平使用热核聚变能源的方式，中国从1990年开始兴建托卡马克实验装置。历时三年建成的中国第一台超导托卡马克装置──ＨＴ－7，使中国成为继俄、法、日之后第四个拥有同类实验装置的国家。"...is pure bullshit. Both the UK and the US were operating large-scale (largest in the world) tokamaks since the 80's. In fact, JET (UK) and TFTR (US) were two of the first tokamaks in the world to use tritium to produce significant amount of fusion power.
It's reaaaaly curious why these well-known facts weren't mentioned.
BTW, in case people don't know, Q=1 has already been achieved. The next generation reactor, ITER, is shooting for Q=10. For a self-sustaining reactor, we really want Q=infinity for "ignition", but that's probably still a few decades away.
