The characteristic of BMS silica mesostructure and the effect of various synthesis factor (including ammonia/silica molar ratio, composition concentration variation, surfactant alkyl chain length, auxiliary organic molecules such as trimethylbenzene, catalyst structure and properties, solvent and cosolvent volume and its polarity, aging and drying conditions and postsynthesis hydrothermal treatment and so on) on the resultant BMS silica structure and properties were assessed using a series of analytical techniques such as XRD, SEM, TEM,〓Si MAS NMR, TG-DTA and N〓 adsorption measurements.
结果显示BMS二氧化硅分子筛是由大量封装胶束的纳米二氧化硅颗粒(约为20-40nm)堆积形成的聚集体,其双介孔分布中较小的介孔起因于颗粒内部表面活性剂模板形成的介孔,我们称之为骨架介孔。它类似于我们在MCM-41中看到的介孔,可通过改变表面活性剂胶束的尺寸而在2.56-3.65nm的范围内进行调节。

The fibrils of three levels,Which were macrofibrils of several tens micron in diameter,fibrils feW micron and microfibrils about 0.3 micron,were observed simultaneously with banded texture usingpolarized microscope.After annealing,fibrils in different levels relaxed to differentmorphology.Macrofibrils still oriented along shear direction,but fibrils relaxed to helical form,and microfibrils relaxed to waveform therefore the banded texture canbe seen.The smaller the diameter of fibrils was,the more easily the fibrils relaxed.Ori the other hand,the banded texture decoration of annealed unoriented filmsrevealed directly the distribution of directors within and out of domains and thevariation of directors on boundaries.
微纤分三个层次,即直径分别为数十微米的微纤束、数微米的微纤和0.3微米的亚微纤,退火后三个层次的微纤松弛成不同的形态,微纤束仍笔直沿剪切方向取向,微纤松弛成螺旋形,而亚微纤松弛成波浪形从而观察到条带织构:微纤直径越小越易松弛,另一方面,非取向态织构退火后由亚微纤形成的条带装饰结果直观地揭示了微区内外分子指向矢的分布和它们在边界上的变化。

Based on both the strong-weak model and the strong-strong model, the instability caused by ions in equilibrium is simulated, some useful results are obtained. The results include the relation between instability growth rate and neutralization factor, the relation between instability threshold and neutralization factor, and the incoherent tune shift, the tune spread, the ion cloud distribution, the ion loss mechanism, as well as the ion accumulation limitation in the storage ring. With this understanding, we have carried out theoretical and experimental study for some ion clearing methods and their effects for the HLS ring. The minimum static clearing voltage is determined through calculating beam electric field and measuring ion current.
