• hau + wai
• hau + totoka
• wai + totoka.

Ki te nga matū e tauhohe ki ia atu kei roto i te āhua taua o te whakawhāititanga, kua karangatia e taua tauhohe ōrite. taea hoki e te iritihia te kupu i te Kariki, "gomos" - te taua, rite.

tauhohe ōrite me heterogeneous noa puta i roto i to tatou oraraa. Whakaaroa, mo te tauira, te rakau tauhohenga ngingiha. Wahie - he, i me te nui, he taonga matū o te take mai waro - cellulose. Te kore te feaa, te rakau - he taonga e te mea i roto i te āhua mārō. tahu ratou e tika ana ki te mahi o te hāora. Hāora - Ko te hau. Ka rite ki te hua, te tauhohenga ngingiha o te wahie i hanga waro, te hauhā me te wai. Ngingiha o te rakau kia rite ki tahu waipiro - he tauhohenga heterogeneous. Ka taea te kawea tauira ki mutu-.

1) te rino Rusting. Tuatahi, he tauhohenga matū, no te mea te hua o te taonga hou i hanga e o rino - waikura rino waihā (III). Tuarua, ko reira he tukanga heterogeneous, mai te rino - ko te totoka , me te wai, me te rangi hāora, e tae mai i raro i te rusting mana - he wai, me te hau te whakaatu i. Ka taea e tenei tukanga kia tuhituhia e te whai ake whārite tauhohe :
