收缩效应

During VVI pacing, ventricular EAS was located at the right ventricular apex, thus resulting in an antidromic ventricular activation sequence from cardiac apex to base, as manifested by the delay and dispersion in phase, while the PS, FWHM and PSD were reduced as compared with those before VVI.

心室激动顺序和心室收缩同步性是维持正常心室功能的重要因素，在时间和空间上保持心室舒缩活动处于一个协调有序的工作状态，从而保证心室射血的力学效应，产生最佳的血流动力学效果。

Can increase the systolic function of heart and blood vessel flexibility, blood flow can change the dynamic effect.

科学的体育运动能增加心脏的收缩功能和血管的弹性，可以改变血流动力效应。

At the beginning, the domestic and external scholars studied it on the cattle, rat, lapin, fish , pig and cat etc , the result showed that the physiological effect of Coriaria lactone was similar to that of picrotoxinin , which effected nerve system , made the muscle and respiration exited and the vascular contracted , animated the heart restraint center so lead to the animal coma , startle , spasm etc symptom .

人们很早就认识到了它的毒性，最初国内外学者分别在牛、鼠、兔、蛙、鱼、猪和猫等动物上研究证明，马桑毒素的生理效应与苦毒素的生理效应极其相似，是通过作用于神经系统，产生肌肉兴奋，呼吸亢奋，血管收缩，激活心动抑制中心等从而导致抽搐、昏迷、惊厥、癫痫等症状。

METHODS: Both diastolic and systolic blood pressures repeated measures data, collected from 120 drug abusers after taking two kinds of medicine (Drug A: Xiaoyinfuzheng, Drug B: Kelening), were analyzed by multivariate random coefficients model. The fixed effect parameters matrix x of model coefficients were estimated by using least squares estimation method, the effects between treatment groups were compared and the variancecovariance matrices of random effect were also estimated.

对两种药物（A药：消瘾扶正胶囊，B药：可乐宁）治疗120例患者后的舒张压和收缩压重复观测数据进行多变量随机系数模型分析，对模型系数的固定效应参数矩阵ξ作最小二乘估计并进行组间比较，同时估计随机效应的方差协方差矩阵，分析方法用SAS/IML软件编程得以实现。

In contrast, the dilatory responses to the nitric oxide donor sodium nitroprusside and olume expansion were enhanced.

与此相反，对硝普纳的扩血管效应则提高。而此些收缩反应和扩血管效应能够被NO合成抑制剂N-硝基-L-精氨酸甲酯所纠正。

Cyperus extract has negative influence on uterine systole especially with tatenus, and the result suggests that Cyperus extract may inhibit oxytocin both via competitive inhibition and physical annihilation.

香附有明显的抑制子宫收缩的效应，并且对缩宫素的效应有直接切实的拮抗作用。缩宫素；香附；子宫平滑肌

The development of magnetic materials was extremely rapid during the 1990's,when magnetic alloys of the rare earth-3d iron group,such as rare earth permanent magnets,giant magnetostriction materials,giant magnetocaloric materials,magnetooptic materials,magnetic amorphous materials,and nanocrystalline magnetic materials,appeared one by one.

稀土-3d过渡族磁性合金材料，如稀土永磁、巨磁致收缩材料、巨磁热效应材料，磁光效应材料等，以及非晶，纳米微晶磁性材料相继问世。1988年巨磁电阻效应的发现已获广泛应用，如读出磁头、传感器以及磁随机存储器等，并发展成为自旋电子学的新学科。

Two critical problems have to be resolved before the itemizing of the load effect can be completed, that is,firstly the removal of temporary elements or restraints should be carried out .

为完成新公路桥规的各项检算，需在计算软件中把荷载效应进行分项，把恒载分为自重、预应力的一次力和二次力、收缩徐变效应。

Fifty six medicat- ed patients were randomly devided into two groups,half of them received the EMG as- sisted RT,the others were only treated by antihypertensive medicine.

肌电生物反馈和松弛训练在和药物共同应用时具有相加效应，产生的降压作用比较缓和，对收缩压的效应先于舒张压。
