The function mechanism among the minerals and floatation drugs had been studied with the way of IR and academic calculation, which pointed out that absorption of G-4 on the surface of phosphorite belonged to physical and chemical types, but the chemical one was in the highest flight. Absorption of amine collector named GE-609 on the surface of quartz belonged to electrostatic and physical type. Distilled water could hardly wash the GE-609 down from the surface of quartz. Leading component of S-721 was the concentrated compound of naphthol sulfonic acid and formaldehyde. The compound had a stronger affinity to the Mg~(2+) on surface of dolomite than the Ca2+ on surface of phosphorite, which is the essential reason in the separation of phosphorite and dolomite. The leading components of soluble glass in function were HSiO3 hydronium and F^SiC^ colloid granule.

通过红外光谱测定以及理论计算的方法研究了选矿药剂与矿物间的作用机理，研究表明：脂肪酸捕收剂G-4对胶磷矿的捕收作用是以化学吸附为主、化学吸附与物理吸附共同作用的结果；胺类阳离子捕收剂GE-609在石英表面的吸附属于静电物理吸附，但很难用水洗的方法使GE-609从石英表面脱附；S-721主要成分为萘酚磺酸与甲醛的缩合物，萘酚磺酸与甲醛的缩合物对白云石表面Mg~(2+)的吸附明显强于对胶磷矿表面Ca~(2+)的吸附，这是胶磷矿与白云石分离的根本原因；水玻璃溶液中对石英起抑制作用的主要组分是HSiO_3~-和H_2SiO_3胶粒，水玻璃除对石英起抑制作用外，对矿浆还具有一定的分散作用。

Its dispersive mechanism was studied briefly with infrared spectrography. The effects of different pH value and SAF dosage on the sedimentation behavior of SiC in the slurry were studied using 10﹪ polyvinyl alcohol water solution as a medium.

通过红外光谱，简要分析了SAF的分散机理，并以含10﹪聚乙烯醇水溶液作为分散介质，研究了不同用量SAF和不同pH值对体系沉降性的影响。

At this annealed condition, the C atoms were easily incorporated into the substitutional sites and no SiC phase was formed.

傅立叶变换红外光谱和RBS研究结果表明，SPE生长的SiGeC薄膜具有较好的外延质量。

When TEOS reacted with moderate water, the β－ SiC with the size of about 15～ 20 nm could be synthesized under both of the acid and basic conditions.

适量水与TEOS反应时，无论是在酸碱条件下都能得到粒径为15～20nm左右的β－SiC粉。

Based on the thermionic emission theory, a simple method to extract parameters of 4H-SiC SBD is given in this study.

目前对这两个参数没有很好的提取方法，严重妨碍着对器件特性的分析和模型的建立。

Three of a kind Sic Bo betting is situated on the top in the center of the board and this lets you guess that all 3 dice will end on the same number.

一类骰投注博三是在位于板中心的顶部，这可以让你猜骰子将所有3月底前在相同的号码。

By adopting the strategy that the different components of the residuals and the noise are approximated by uncorrelated random variables after the SIC,the complexity of the algorithm can be greatly reduced as the matrix inversion for MMSE is not necessary.

该算法通过将软干扰消除后的残余干扰和噪声的各分量近似为不相关的随机变量，使得在MMSE滤波时不必矩阵求逆，从而大大降低了计算复杂度。
