張載的哲學內涵浩瀚龐大，學界多有人認為張載所闡發者乃是以氣化為主的氣論哲學，但本文另持異議，不贊同張載哲學乃一氣論哲學。本文發端即列舉幾位當代詮釋張子哲學的知名學者，論其精妙與不足之處，總結以牟宗三先生的詮解乃最符合張載原意者。 以牟先生之講論為依據，綜合張載哲學之中心意旨乃在「參兩通一」之妙義，而參兩通一原則主要包含三個意義：兼體不累、參天兩地與性總合兩三層義理。總合這三個意思而界定參兩通一，發現此原則也適用在其他理學家的哲學論述，意即此原則是一普遍性原則，可當作儒家形上學之共法，由此原則而入，可以了解儒家形上學之意涵，本文特舉程顥、楊簡二人為證。

Zhang Zai's philosophy is very huge and complicated, a lot of people think that his philosophy is to talk about the manifestation of Chi, but I thought that cognition was incorrect. This article lists some scholars who interpret Zhang Zai's philosophy well-known at the beginning, but just Mou,Zong-San's interpretation is correct, that is the last conclusion. To base on Mr.Mou's explanation, we can synthesis a main idea is "partaking two harmoniously and leading to one". This principle applies to other Confucian scholars too, in other words, this principle is a universality principle, can regard as a common rule of the Confucianist metaphysics. To understand this rule is equal to know the Confucianist metaphysics too. In order to prove this point of view, this text especially bringing up Cheng Hao and Yang Jian two people.
