歧伯對曰：診法常以平旦，陰氣未動，陽氣未散，飲食未進，經脉未盛，絡脉調匀，氣血未亂，故乃可診有過之脉。
岐伯对曰：诊法常以平旦，阴气未动，阳气未散，饮食未进，经脉未盛，络脉调匀，气血未乱，故乃可诊有过之脉。
qí bó duì yuē: zhěn fǎ cháng yǐ píng dàn, yīn qì wèi dòng, yáng qì wèi sàn, yǐn shí wèi jìn, jīng mài wèi shèng, luò mài tiáo yún, qì xuè wèi luàn, gù nǎi kě zhěn yǒu guò zhī mài.
Qibo replies: Diagnosis is regularly done at dawn. The yin qi has not yet stirred, the yang qi has not yet dispersed, food and drink have not yet been taken, the conduit vessels are not yet full, the network vessels are evenly regulated, and the qi and blood are not yet disordered — therefore one can examine the pulse for what is amiss.
「診法常以平旦」為本篇第一義：必於陰陽未動、飲食未進之時取脈，而後「有過之脉」可診。此與後世診前令病人安坐片刻同一意，惟本篇著之為法。
故曰：陰中有陰，陽中有陽。平旦至日中，天之陽，陽中之陽也；日中至黃昏，天之陽，陽中之陰也；合夜至雞鳴，天之陰，陰中之陰也；雞鳴至平旦，天之陰，陰中之陽也。
故曰：阴中有阴，阳中有阳。平旦至日中，天之阳，阳中之阳也；日中至黄昏，天之阳，阳中之阴也；合夜至鸡鸣，天之阴，阴中之阴也；鸡鸣至平旦，天之阴，阴中之阳也。
gù yuē: yīn zhōng yǒu yīn, yáng zhōng yǒu yáng. píng dàn zhì rì zhōng, tiān zhī yáng, yáng zhōng zhī yáng yě; rì zhōng zhì huáng hūn, tiān zhī yáng, yáng zhōng zhī yīn yě; hé yè zhì jī míng, tiān zhī yīn, yīn zhōng zhī yīn yě; jī míng zhì píng dàn, tiān zhī yīn, yīn zhōng zhī yáng yě.
Thus it is said: within yin there is yin, within yang there is yang. From dawn to midday is the yang of heaven — the yang within yang. From midday to dusk is the yang of heaven — the yin within yang. From nightfall to cockcrow is the yin of heaven — the yin within yin. From cockcrow to dawn is the yin of heaven — the yang within yin.
「平旦至日中」——以一日分四時：平旦至日中為陽中之陽，日中至黃昏為陽中之陰，合夜至雞鳴為陰中之陰，雞鳴至平旦為陰中之陽；**「平旦」本篇2見**
故陽氣者，一日而主外，平旦人氣生，日中而陽氣隆，日西而陽氣已虚，氣門乃閉。是故暮而收拒，無擾筋骨，無見霧露。反此三時，形乃困薄。
故阳气者，一日而主外，平旦人气生，日中而阳气隆，日西而阳气已虚，气门乃闭。是故暮而收拒，无扰筋骨，无见雾露。反此三时，形乃困薄。
Gù yáng qì zhě, yī rì ér zhǔ wài, píng dàn rén qì shēng, rì zhōng ér yáng qì lóng, rì xī ér yáng qì yǐ xū, qì mén nǎi bì. shì gù mù ér shōu jù, wú rǎo jīn gǔ, wú jiàn wù lù. fǎn cǐ sān shí, xíng nǎi kùn bó.
The yang qi governs the outside through the day: at daybreak the human qi is born, at midday the yang qi is at its height, and at sunset it is already empty, so the gate of qi closes. Hence at dusk one gathers in and refuses the outside, disturbing neither sinew nor bone and meeting neither mist nor dew. To go against these three times of day leaves the form worn and thin.
「平旦人氣生」——平旦謂旦明之時；本篇以一日分三時，平旦、日中、日西，人氣與陽氣相為消長；**「平旦」本篇1見**
是故寒熱病者，以平旦死。熱中及熱病者，以日中死。病風者，以日夕死。病水者，以夜半死。其脉乍疏乍數，乍遲乍疾者，日乘四季死。

Shì gù hán rè bìng zhě, yǐ píng dàn sǐ. Rè zhōng jí rè bìng zhě, yǐ rì zhōng sǐ. Bìng fēng zhě, yǐ rì xī sǐ. Bìng shuǐ zhě, yǐ yè bàn sǐ. Qí mài zhà shū zhà shuò, zhà chí zhà jí zhě, rì chéng sì jì sǐ.
Thus cold-heat disease kills at daybreak; internal heat and heat disease kill at noon; wind disease kills at sunset; water disease kills at midnight. One whose pulse is now scattered, now rapid, now slow, now hurried dies on a day that mounts the four quarters of the year.
