dilute base

基本解释

Will Yellow Dog now advertise itself as the choice of Mac users and thereby dilute its hard core fan base?
Yellow dog将会像现在这样子把自己打造成Mac用户的一个选择而因此冲淡自己的核心爱好者阵营吗（我觉得这里逻辑不对）？
The diacid could react with divinyl ether, such as 1,3-divinyloxyethoxybenzene, in solid film when baked above 80 ℃ and the film became insoluble in dilute base aqueous.
丙烯海松酸有大的脂环结构和良好的成膜性，在固体膜层中，它可以和二乙烯基醚，如1，3-二乙烯氧基乙氧基苯，在加热条件下（80℃以上）发生反应，产物在稀碱水中难溶。
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。
