In order to application on high resolution of liquid crystal display, which must reduce differential error voltage in digital-to-analog converter circuit. So, how to reduce the offset voltage of buffer amplifier is important. In the second buffer amplifier circuit, to promote the open-loop gain to reduce offset voltage.

若要使液晶显示器的色彩深度能够大幅提升，就必须采用位元数较高的数位类比转换电路，也就表示其输出的每一灰阶类比电压值的差将会随著位元数的增加而变小，因此输出缓冲放大器的偏移电压就显的特别重要。

With increasing age, the activity of joint becomes less or pressed by gravity. For example, fatness will make cartilage atrophy, bruised and surfaces of joint will not be even, more seriously, cartilage will completely lose the function.

中文摘要摘要随著年纪的增加、生理性关节活动变小或重力的压迫，例如肥胖会使软骨退化、磨损、关节表面凹凸不平，严重时软骨会完全丧失，骨头与骨头直接接触会导致发炎、红肿、疼痛，甚至无法正常弯曲、移动。

The reason is that B group disturbed the crystallite structure and reduced crystallinte size.

原因是个基团B破坏了晶体结构使球晶的尺寸变小。

The resulting materials were characterized by x-ray diffraction, Fourier transform infrared spectroscopy, Nuclear magnetic resonance and Photoluminescence. Those spectra reveal that by adding SiO2 to YAG:Ce precursor, the lattice constant decreases while vacancies are generate due to the co-dopant ions (Si4+) replaces in the place of Al3+ sites of YAG:Ce system. YAG:Ce phosphors with Y3+ dodecahedral site replaced by Ce3+ and diffused effectively as an activator, as a result the photoluminescence intensity increased about ~20-30%.

研究成果显示，掺杂SiO2之YAG：Ce萤光粉经过高温热处理后，由X光绕射、红外线吸收光谱仪以及核磁共振可以得知，当SiO2添加量增加时，YAG：Ce晶格常数会因为Si4+取代Al3+的四面体晶格位置而变小，同时产生将YAG：Ce之铝离子空位缺陷，使活化中心更有效地在YAG：Ce主体中扩散取代Y3+的十二面体晶格位置，提高其发光性质约20~35%。

That leaves Wang at the mercy of his defense, specifically his infield defense.

这使的小王身后的防守变的很重要，尤其是内野。。。。。。

The soil cutting experiment indicates that the interior friction angle and the shear intensity of soil is reduced;and the maximum principal stress is decreased due to the vibration load;it induces the decrease of digging resistance.

从理论上研究了振动掘削岩土的减阻机理，土壤剪切试验结果表明，振动载荷能够使土壤的内摩擦角变小、抗剪强度下降、最大主应力值减小，从而导致挖掘阻力降低；对土壤在静态载荷和振动载荷作用下的失效过程进行了对比仿真实验研究，可知土壤在振动加载的条件下强度显著下降，并提前于相同条件的静态加载而破坏，同时跟踪X方向的载荷发现，振动掘削最大掘削阻力可降低50%。

A new method to identify _ amylase activity and its producing bacteria : the blue complex was formed by unspecific adsorption , after mixing starch and trypan _ blue . the adsorption weakened when the starch was hydrolyzed to small molecular by _ amylase , and the trypan _ blue was released inside the hydrolyed zone . the starch around the zone which was not hydrolyzed adsorbed free trypan - blue so that the colour of medium became bluer than that of place in hydrolyzed zone

快速鉴定并筛选-淀粉酶及其产生菌的新方法：锥虫蓝染料和淀粉由于静电非特异性吸附结合后使淀粉呈稳定的蓝色，当淀粉被淀粉酶水解后因分子变小吸附力减弱，而让锥虫蓝游离出来，游离的锥虫蓝被周围未水解的淀粉吸附而使颜色加深，淀粉水解区则形成无色、透明的水解圈。
