The calculated results show that the enhancement factor increases with the increase of absorbability of particles.

计算结果表明：增强因子随微粒吸附容量的增大显著增加；微粒距离气液界面越远，微粒吸附能力对气液传质的增强越小；在相同粒径与微粒距离气液界面距离的条件下，增强因子随微粒在气液停留时间的增加而增加，但是当停留时间超过一定值后，随着停留时间的增加，增强因子下降；粒径增大，增强因子减小。

Correlation between spin angular momentum s and background angular momentums of planets;2. In the paper the principle of optical rotation due to the transfer of spin angular momentum from light to particles was discussed by analyzing the interaction between the beam of light and birefringent crystal particles, and then an optical tweezers was formed on nanometer optical tweezers system with a linearly polarized light beam (He-Ne laser 633 nm, 10 mW).

The experiments show that the PS and PSD of particles produced by SAA process can be controlled by adjusting process parameters, and among them, the pressure of the saturator used has the most effect on the PS and PSD, while the temperature of the saturator has the least effect. When using ethanol as solvent, the optimum operating conditions of using SAA process to produce erythromycin micro-particles from erythromycin-ethanol-CO2 system were found as follows. The pressure and temperature of the saturator are 10.5MPa and 70℃, respectively, the inlet flow rate and the concentration of inlet solution of the precipitator are 9 mLmin^(-1) and 15mgmL^(-1), respectively.

实验结果表明：选用乙醇做溶剂可制备出粒径在1~3μm的红霉素超细微粒，大部分微粒形态呈完整的球形；各影响因素对微粒粒径及粒径分布均有不同程度的影响，其中混合器压力对微粒粒径及粒径分布的影响最明显，混合器温度的影响最小，微粒粒径及粒径分布可通过改变操作参数进行控制；在本研究范围内，最优操作条件为混合器压力10.5MPa，混合器温度70℃，溶液浓度15mgmin^(1)，进液速度9mLmin^(1)。

Methods: 1 HA particles were put into two kinds of solutions, which contained HA or Brushite microparticles, respectively. After vibrating for different time, the number of the microparticles attached to HA particles was measured and compared. 2 The solution containing HA microparticles was painted on the surfaces of exposed dentinal tubules to investigate the sealing effect of HA microparticles on dentinal tubules using ESM.
