Compared with the same wave problems with conventional Dirichlet boundary conditions, the absorbing boundary conditions can reduce the numerical reflection on boundaries and avoid solution distortion. In addition, the central differences method is economic in memory requirement and computing time compared with implicit integral method.

结果表明：该解法在空间上具有谱精度，在时间上达到二阶精度；与第一类边界条件相比，吸收边界有效地削弱了边界上的数值反射，避免了解的失真；使用中心差分的时间积分方法同隐式积分方法相比，适合波的传播特性，避免了矩阵求逆运算，并且占用的计算机内存小。

According to the designated discussant, Robert Eckel, MD, president of the American Heart Association and chairman of atherosclerosis at the University of Colorado at Denver Health Sciences Center, the TNT study shows that "lower is also better" for cerebrovascular events in patients with coronary heart disease.

美国心脏医学会总裁，同时也是科罗拉多大学丹佛健康科学中心，粥状动脉硬化研究主席Robert Eckel医师表示，TNT试验证实降低LDL－C不但对冠状动脉心血管疾病病患有益，对降低脑血管事件的发生率同样是有效的。

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%。

The expert reminds the information safety of center of Chinese finance attestation say, want silver-colored security of net of rational look upon, what at present domestic network silver cast off pair of Zhang date and password already is pure depend on, use the attestation method of double element, much element generally, Want to take significant step only, the bank on the net can be at ease use.

Pascal James Imperato, dean of the graduate program in public health at the State University of New York Downstate Medical Center in New York City and a former New York city health commissioner said," The fact that they were able to do this, and very efficiently, and get such good antibody response reinforces and reconfirms that, even for the annual flu virus, we need to move away from embryonated hens' eggs ".

博士帕斯卡尔詹姆斯imperato ，院长，研究生院计划在公共卫生方面，在纽州立大学医学中心downstate在纽约市和前纽约市卫生专员说："事实上，他们能够做到这一点，和非常有效，并取得这样的好抗体反应巩固和确，即使是每年的流感病毒，我们需要迁离蛋鸡鸡胚蛋"。
