The results of DLVO theoretical calculations indicate that the total acting energy between the titanaugite and ilmenite particles at pH 5.9 is negative, showing as attraction, which causes the superfine titanaugite particles attach on the surface of ilmenite. At pH 8.5, because of large electrostatic repulsion energy, the total acting energy shows as strong repulsion, thus the superfine titanaugite particles can not attach on the surface of ilmenite.

DLVO理论计算结果表明：当pH=5.9时，两种矿物颗粒间的总相互作用能为负值，表现为相互吸引，微细粒级的钛辉石会在钛铁矿表面上粘附，使钛铁矿的回收率显著降低；当pH=8.5时，由于静电排斥能大，总相互作用能仍表现为较强的排斥力，微细粒钛辉石不能粘附在钛铁矿表面。

Two key advantages of functionalized carbon nanotubes are their strong ability to translocate through plasma membranes and low toxicity, allowing their application in drug and gene transfer system.

This is enough to make Fantasia better as an album and a statement of purpose than Free Yourself, but no matter how good tracks like "Uneligible" sound - and with its fuzz-toned instrumental breaks and skeletal beats, this track does sound pretty great — it's hard not to wish that there were hooks as memorable as the production.

就这点已足以使Fantasia质量优于且目的强于前专辑Free Yourself。像&Uneligible&这样的歌如此地好听——它柔和的曲调，精粹的乐队演奏和独敲的鼓点——的确让该曲非比寻常——你很难不期望该制作不给你难忘的印象。

Due to the fact that water molecule acquired energy from magnetic field and the molecule rotated faster after magnetization process, the growth speed of Escherichia-coli cultivated with magnetized water is faster than that cultivated by unmagnetized tri-distilled, which proved that magnetized water possesses stronger penetrability and solvency.

蛋白质水接触的几率也随之增加，所以磁化水对于蛋白质的结构将有一定的影响。由于磁化过的水水分子活动加快，并获得了高能量，使磁化水培养的大肠肝菌生长速率比普通三蒸水培养的大肠肝菌生长速率快，这就进一步证明了磁化水具有较强的渗透性和对可溶性物质的溶解能力。

However, the control performance of the PMSM drive is still influenced by uncertainties, which usually features parameter variations, external load disturbances, unmodelled and nonlinear dynamics. To achieve high-performance PMSM drive, which has great ability of adaptation and better performance against disturbances, advanced control schemes have to be developed to deal with these uncertainties.

然而，由于永磁同步电机驱动系统受电机参数变化、外部负载扰动、对象未建模和非线性动态等不确定性的影响，要获得高性能的永磁同步电机驱动系统，必须研究先进的控制策略以解决这些不确定性的影响，使系统具有较强的自适应能力和抗干扰能力。

The research which is the important part of the tunable erbium-doped fiber laser is composed of two main parts: 1. the gain part of the tunable erbium-doped fiber laser, which in fact is an erbium-doped fiber amplifier, its output characteristics are discussed both in theory and experiment, and the differences are also discussed between theory and experiment; 2. the saturated absorber part of the tunable erbium-doped fiber laser, also the part to narrow the line width of the fiber laser. The line-width narrowing mechanism in fiber laser induced by unpumped Er-doped fiber is presented from the aspect of coupling wave equation, and the main factor is considered as the standing wave induced by interference. The line-width is narrower when the standing wave is stronger, and the narrowing effect disappears with the disappearance of the standing wave. In the experiment, when adding a Faraday mirror in the laser cavity to remove the standing wave , the narrowing effect disappears. So the theory is proved by the result of the experiment.

本课题的研究内容是集成光学声光可调谐掺铒光纤激光器的重要组成部分，主要分两部分：1、声光可调谐掺铒光纤激光器中增益部分的研究，相当于对掺铒光纤放大器的研究，理论上对掺铒光纤放大器的输出特性进行分析，实验上实现了掺铒光纤放大器系统，并将实验数据与理论计算数据进行对比，分析了误差产生原因；2、声光可调谐掺铒光纤激光器中饱和吸收体部分的研究，即压窄光纤激光器输出线宽的研究，从耦合波方程出发，理论上解释了未泵浦掺铒光纤压窄光纤激光器线宽的原理，分析了影响该作用的主要因素是未泵浦掺铒光纤中相对传输的光干涉形成的驻波：驻波越强，压窄效果越好，相反当没有驻波时，没有压窄效果，在实验上通过在激光器腔内加入法拉第旋转镜使驻波消失，同时压窄效果消失，从而验证了理论分析的正确性。
