High internal phase ratio (HIPR) aqueous Janus emulsions of two immiscible oils, silicone oil (SO) and a vegetable oil (VO), were prepared using a vibration mixer. The simple HIPR Janus emulsions, (VO + SO)/W, were found at weight fractions of the aqueous phase in excess of 0.3, while at a corresponding fraction of 0.1, a triple emulsion was obtained with the Janus emulsion forming a drop inside the vegetable oil to give a double Janus emulsion, (VO + SO)/W/VO, which in turn formed drops in the silicone oil resulting in a triple Janus emulsion (VO + SO)/W/VO/SO. Increasing the aqueous-phase fraction from 0.1 to 0.3 consequently meant an inversion, of which one intermediate stage was observed: a more complex configuration, e.g., one in which large SO drops with highly distorted VO drops attached were dispersed in a regular aqueous emulsion with spherical Janus (VO + SO) drops. A preliminary investigation was made into the destabilization process of the triple emulsions.
高内相比（HIPR）水包二相非均相 Janus 乳液由两种不混溶的油，硅油（SO）和植物油（VO），使用振动混合器制备。在水相重量分数超过 0.3 的情况下，发现了简单的 HIPR Janus 乳液（VO+SO）/W，而在相应的分数为 0.1 的情况下，得到了具有 Janus 乳液形成植物油内液滴的三重乳液，从而形成双 Janus 乳液（VO+SO）/W/VO，其转而在硅油中形成液滴，从而得到三重 Janus 乳液（VO+SO）/W/VO/SO。从 0.1 到 0.3 增加水相分数意味着反转，其中观察到一个中间阶段：更复杂的配置，例如，具有附着的高度变形 VO 液滴的大 SO 液滴分散在具有球形 Janus（VO+SO）液滴的规则水乳液中。对三重乳液的失稳过程进行了初步研究。
