It was suggested that aging did not only influence diastolic filling period, but also influence STI. 3. With increasing age, whether at rest or during exercice, fractional shortening of minor semiaxis, mean velocity of circumferential fiber shortening, cardiac index and ejection fraction did not change, but immediately post pacing, PEP prolonged and PEP/ LVET increased in elderly group and did not change in young group. It was suggested that STI was sensitivity in detecting systolic function of LV. 4. There was a good correlation between aging and decreased compliance and diastolic function of left ventricle which was manifested by a reduction of early diastolic peak folw velocity, time-velocity integral of early diastole, 1/3 filling fraction (1/3FF)(r=-0.958,-0.875 and -0.937, P＜0.01～0.001) and a significant compansatory increase in peak flow velocity of atrial contraction, time-velocity integral of atrial contraction, the ratio between APFV and EPFV and the ratio of ATVI and Total TVI (r=0.958, 0.956, 0.966 and 0.986, P＜0.001) and the prolongation of Dec T and RFP with increasing age. It was particularly true for the subgroups above the age of 50 years.

静息状态下收缩时间间期与年龄无相关性，负荷后即刻，老年组射血前期延长(P＜0.05)，射血前期与射血期比值加大(P＜0.05)，青年组无变化，提示年龄因素亦影响STI，但由于静息状态下得到代偿，STI变化往往表现不明显。3、静息及负荷状态左室短轴缩短率、平均周径缩短率、心指数及射血分数均不随年龄增长而变化，而负荷后即刻老年组PEF延长，PEP/LVET加大，提示STI是检测左室收缩功能的敏感指标。4、随年龄增长，心房收缩期充盈峰值流速、流速积分、充盈分数及心房收缩期与舒张早期充盈峰值流速之比值显著增高(r＝0.958、0.956、0.986及0.966，P均＜0.001)，舒张早期充盈峰值流速及流速积分、1/3充盈分数(1/3FF)下降(r＝-0.958、-0.875及-0.937，P＜0.01～0.001)。

Moreover, their contraction scale,contraction velocity and relaxation speed were significantly reduced in a dose-dependent manner.

The basic view of the model that the intense subduction of the Indian plate beneath tbe Eurasian plate would result in inhomogeneity of the fabric and deformation of the lithosphere and repeated alternations of normal transformation from collision to contraction to stretching and reverse transformation from stretching to contraction.

其基本观点是强调由于印度板块向欧亚板块的强烈俯冲造成岩石圈组构和变形的不均一性及岩石圈中存在的碰撞→收缩→伸展的正向转变和由伸展→收缩的逆向转变的反复交替。

So RTR75 at the second fatigued contraction was reduced after 5 or 10 min of recovery, but no significant difference after 60 min of recovery. During intermittent tetanic contraction RTR75 was increased to be 2.9 times of normal in unloaded soleus.

但是，这些方法大部分是在非完整肌纤维或细胞上进行观测，受诸多测试因素的影响，有时不能反映在体肌纤维SR钙转运的实际功能。

The studies show that the nonlinear concrete model has great effects on the dynamic open displacement of contraction joints subjected to intense earthquake because of the nonlinear softening and local damage and cracking. This is very important to the performance of the water-tight in contraction joints.

研究表明，由于在地震过程中的混凝土非线性软化以及局部损伤开裂的影响，非线性拱坝横缝的开度及分布与采用线弹性砼本构关系计算结果有明显的不同，这对于横缝止水的设置具有重要影响。

Owing to the improvement of the biological technique, the unprecedented progress to the research of the muscular contraction property under different biochemistry conditions and the mechanism of the flagella and cilia"s bending have been made.

由于近年来生物技术的不断提高，使得对肌肉在各种生化状态下收缩性质、鞭毛和纤毛的拍击机制的研究取得了较大进展，本文拟对肌肉收缩过程中ATP浓度变化规律和鞭毛拍击的特征做一些理论研究。

In fundic strips, ghrelin and GHRP-6 could decrease the on-response induced relaxation and increase off-response induced contraction of the muscle, with the effect of Ghrelin obviously stronger than that of GHRP-6.L-NNA could increase the effects of Ghrelin and GHRP-6-induced muscle contraction, and L-AA could decrease their effects.

在胃底部，Ghrelin和GHRP-6可使开电刺激诱导的平滑肌舒张活动减弱，断电刺激诱导的肌条收缩活动增强，且Ghrelin作用明显强于GHRP-6.L-NNA可显著增强Ghrelin和GHRP-6的促平滑肌收缩效应，但L-AA可显著减弱该作用。
