The cold light fair instrument principle is to lie a wave-length the high strength between the 480-520 nanometers is only blue, through more than 12000 roots, the total length more than 1 mile fiber-optic conductions, again pass 2 slices Be plated the optical mirror slice of film processing by 30 many times, separate place the whole harmful purple outside and only with infrared ray, irradiation go to daubery on the special fair on the tooth, in the shortest time inside make fair through tooth essence small tube and many in the last years the deposition oxidize revivification function in the tooth surface and the deep dye creation and make the tooth returned to before having not yet dye of pure.

冷光美白仪原理是将波长介于480-520nanometer之间的高强度蓝光，经由12000多根、总长度超过一英哩的光纤传导，再通过两片经30多次镀膜处理的光学镜片，隔处了一切有害的紫外光与红外线，照射到涂抹在牙齿上的特殊美白剂上，在最短的时间内使美白剂透过牙本质小管与多年来沉积在牙齿表面及深层的色素产生氧化还原作用，使牙齿回到未经染色前的洁白。

A series of compounds have been synthesized and characterized by means of DCC method, aqueous solution reaction conditions and hydrothermal reaction conditions.

实验结果表明，修饰后的电极在酸性水溶液中有非常好的稳定性，上百次的连续扫描和长时间在空气中的放置，对电极的氧化还原性质没有明显的影响。

Guanosine monophosphate reductase catalyzes the NADPH-dependent reductive deamination of Guanosine monophosphate to inosine monophosphate .

鸟苷酸还原酶(guanosine monophosphate reductase，GMPR)(EC 1.6.6.8)主要催化鸟嘌呤核苷酸向次黄嘌呤核苷酸的转化：GMP+NADPH+2〓→IMP+〓+NADP〓。

Due to the intense decalescence that most of heat was supplied to gasification, it is the reason of high ash fusibility temperature that there is hardly any Ca and Fe can be deoxidized in gasification.

在气化反应的过程中，由于气化反应为强吸热过程，大部分热量提供给煤炭气化反应，导致Ca与Fe元素的还原反应进行缓慢，灰熔融温度比较高。

Thereafter, the sequential process would involve a solid/liquid separation, reduced sulphuric acid leaching, counter current decantation, solvent extraction of the copper and cobalt and their electro-winning to produce high purity copper and cobalt cathode metal.

后续程序还包括固液分离，简化的硫酸过滤处理，逆流移注（这个词翻译可能不准，请自己调整），铜和钴的溶媒萃取和电解来生产/还原出高纯度的阴极金属铜和钴。

The results that the ultrasonic intensity have a direct ratio to the currents at electrode, when using this methods in the reduction of 〓 at Pt microelectrode, shown the manner of ultrasonic effect on the mass transfer on the electrode surface. And the inverse ratio relationship of current amplitudes to the separation of horn-electrode shown the decay law of ultrasonic intensity with distance.

将这一方法应用于铂电极上铁氰化钾还原反应体系中的研究结果表明，超声功率与电极反应电流幅值信号呈正比的关系，反映了超声能量对电极表面传质过程的影响程度的对应关系；电流信号幅值与超声作用距离的反比例关系则反映了超声振动能量随其辐射距离增大而衰减的规律性。
