针对稀溶液的相平衡的特点，提出了适用于气液色谱法测定模型的稀溶液活度系数表达式。
In this paper expressions for activity coefficients of dilute solutions are derived, which are suitable for working equations for vapor liquid equilibrium measurements by gas chromatography.
这类聚合物的双叠氮交联剂组成的负型感光树脂具有高感度，高分辨率，稀碱水显影以及优良的抗蚀性能。
Some of the negative photopolymers composed of these polymers and bisazides can be developed in dilute aqueous base easily and clearly with excellent performance on photosensitivity and residual film.
这是值得反复来说的：全合成10w -30是基于100度粘度更高的30粘度级基础油，而矿物油10 W - 30是基于100度粘度更稀的10粘度级基础油。
This is worth repeating: the synthetic 10w-30 grade oil is based on a heavier 30 grade oil while the mineral based 10w-30 oil is based on a thinner 10 grade oil.
