tetra-的參考例句
1.The styrene-acrylic emulsion modified by double hydroxyl tetra-coordinated silicon was prepared by free radical emulsion polymerization. 通過乳液聚合方法，制備了雙羥基四配位硅改性苯丙乳液；
2.The optimum proportion for preparation of excellent emulsion was 2% content of emulsion agent, 40% content of solid, 2% content of double hydroxyl-tetra-coordinate silicon. 並得出2%含量的雙羥基四配位硅改性2%乳化劑、40%固含量的苯丙乳液性能最佳。
3.High dispersion of tetra-coordinated titanium is achieved by means of adjusting optimal combination of titanium and silicon atoms, hence the activity of the materials can be improved. 通過硅鈦原子的合理匹配可以達到四配位鈦的高度分散，從而提高催化活性。硅烷化處理增加材料表面的疏水性，能夠大幅度提高活性和選擇性。
