For both series of heteroleptic tris rare earth compounds, the characteristic phthalocyanine dianion IR bands for Pc2- and O OPc2- at ca. 1329 and 1380 cm-1 attributed to the pyrrole stretching and the symmetric C-H bending of -CH3 groups in octyloxy side chains of OOPc rings together with some small contribution from the isoindole stretching vibrations,re specteively,are simultaneously found in their IR spectra.

在这两个不对称三明治型稀土配合物系列的红外光谱中发现了这样一种特性，即酞菁阴离子Pc~(2-)和OOPc~(2-)的特征波段在1329cm~(-1)和1380cm~(-1)之间，这是因为吡咯的伸缩振动和OOPc环中八烷氧基侧链上-CH_3基团的对称C-H的弯曲振动共同作用于吲哚环的伸缩振动。

We compared the effect of the number of weekly repetitions of a static stretching program on the flexibility, hamstring tightness and electromyographic activity of the hamstring and of the triceps surae muscles. Thirty-one healthy subjects with hamstring tightness, defined as the inability to perform total knee extension, and shortened triceps surae, defined by a tibiotarsal angle wider than 90 degrees during trunk flexion, were divided into three groups: G1 performed the stretching exercises once a week; G2, three times a week, and G3, five times a week.

我们比较每周重复静态牵张方案的次数对灵活性、腘绳肌紧张以及腘绳肌与小腿三头肌的肌电灵敏度的影响。31例腘绳肌紧张的健康受试者（腘绳肌紧张为无法进行全膝伸展和小腿三头肌缩短（躯干弯曲时胫附的角度大于90度））被分为3组：G1组，进行每周一次的牵张训练；G2组，进行每周三次的牵张训练；G3组，进行每周五次的牵张训练。

Seven polyimides were synthesized and their films were uniaxially stretched to observe the variation in their in-plane birefringence. The creep method of DMA was used instead in stretching the PI films. The preload force and isothermal temperature were the two controlled factors that were chosen on the basis of the lowest stretchable force and lowest temperature for each PI structure. The elongation ratio of a PI film was then decided by the stretching time.

在此是以DMA 的另一种试片拉伸方式-Creep模式，来取代之前的Stress Relaxation模式对PI薄膜试片进行拉伸实验，Creep模式是以最低的拉伸力量及最低的拉伸温度的前提下，选择Pre-load Force与Isothermal Temperature这二项为拉伸控制因素，在此状态下的PI薄膜拉伸比是取决於其拉伸的时间，此种拉伸模式将可得到较高的拉伸比，而高的拉伸比是获取较高薄膜双折射率的必要条件。

DSC results show that crystallinity of the geogrids ribs is different owing to various stretching technical factors, and that the crystallinity of the stretched sample is larger than the unstretched one. The crystallinities of the sample are similar at lower draw temperature and higher draw speed, which show that there is correlation among the stretching factors.

通过对试样肋条部位结构的DSC分析，发现拉伸工艺参数不同，肋条部位的结晶度不同，且拉伸后试样的结晶度均比未拉伸时有所提高；较低拉伸温度下与较高拉伸速率下试样的结晶度相近，表明各拉伸参数之间具有一定的关联性。

The model of 3-dimensional stretching vortex ring of turbulent elliptic jet in crossflow are discovered for the first time. It is pointed out that in the evolution of turbulent jet in crossflow the 3D vortex rings, which stretching, distorting, swing in transverse direction and twisting around the stream-wise, play the leading role in the large-scale coherent structures. The counter-rotating vortex pair observed in the literature is in fact the head of the 3-dimensional vortex ring.
