AIM: Pristine investigation demonstrated that TJU103 could markedly decrease graft versus host disease incidence and intensity, and obviously prolonge life span after allogenetic haemopoietic stem cell transplantation in mice.

目的：前期研究表明，吲哚亚甲基异烟腙(简称TJU103)可以明显降低异基因造血干细胞移植小鼠移植物抗宿主病的发生率和程度，明显延长小鼠移植后的生存期。

Barrel is the key part of artillery. In shot process, propellent gas of high pressure and high temperature flows in the tube at a high rate of speed, which brings an upheaval to the temperature field of the composite barrel. As to the composite barrel with metal inner, its poor thermal conductivity is more likely to cause uneven temperature distribution and bigger temperature gradient, to produce improper deformation and to make the work temperature of metal inner rise, all of which will affect the life span of barrel.

身管是火炮的关键部件，在火炮发射过程中，高温、高压的火药燃气在身管内成脉冲式高速流动，使身管受到急剧的加热，引起身管壁内的温度急剧变化，而对于带金属内衬复合材料身管，由于复合材料导热性能较差，更容易引起非均匀温度分布以及较大的温度梯度，产生不合适的变形，也会使身管的金属内衬的工作温度升高，从而使得身管的寿命降低，同时身管的发热会引起其刚度的变化，增大射弹散布。

As the life span of human beings increasing, the number of people with senile pruritus has increased, too.

随着人口寿命的增加，老年皮肤瘙痒症的发病率也不断升高。

Memory quotient in unmedicated group showed no significant difference as compared with control group, but the digit span and visual reproduction subtest scores in TS group were signifi- cantly lower than those in control group.

未用药组的记忆商与对照组相比无显著差异，TS组的背数和视觉再生分测验量表分显著低于对照组，提示TS患儿总的记忆功能正常，但其记忆模式中的瞬时记忆和短时记忆可能存在一定的缺陷。

分析了各腔长度的变化对类TM0102π/3模式及其频率、各腔纵向场分量Ez大小及Ez径向分布的影响。

The researchers determined that over a span of 46 million years, rafflesia's flowers evolved a 79-fold increase in size before assuming a slower evolutionary pace.

研究者们认为在长达4600万年的时间中，大花草花的尺寸增长了79倍，之后才以一较慢的速度进化。

Through over-all stability analysis, the influence of height-span ratio, rafter slope to the stability and the effective factors of gable portal frames are also presented in this paper.

通过对门式刚架的整体稳定分析，研究了刚架的高跨比、斜梁坡度对结构的稳定和计算长度系数的影响。

Steel through truss bridge is widely applied in railroading, certainly technology is maturely,but there are some difficulty in hight road,such as long transverse span, sphalt concrete surfacing of orthotropic steel deck plates.

虽然钢桁架桥在铁路工程中较多采用，技术已较成熟，但在公路桥梁中因其横向跨度大、正交异性板钢桥面铺装层问题较难处理。

His teaching began at the Massachusetts Institute of Technology, but William Rainey Harper lured him to the new SPAN
