Heart failure gratified the function is not complete , it is to show the case that has circumfluence of blood of right amount vein falls , because the heart is long - term bear is overweight or heart myapathies caustic makes force of cardiac muscle systole drops , heart cannot enough blood satisfies eduction constituent metabolization need so that all round constituent perfusion inadequacy and pulmonary circulation or blood of systematic circulation yu , a series of clinical symptoms that appear thereby and body are asked for , say for heart failure 心力衰竭又称心功能不全,是指有适量静脉血回流的情况下,由于心脏长期负荷过重或心肌病损使心肌收缩力下降,心脏不能排出足够血液满足组织代谢需要以至于四周组织灌注不足和肺循环或体循环瘀血,从而出现的一系列临床症状和体征,称之为心力衰竭。
Main working principal is that the bottom scraper with low rotate speed impels materials to form circumfluence in the basin of machine , the impeller of rotor rotating with medium speed can not only add wallop to sand , but also can add shear force to the sand with scraper so that the sand can touch and scrub each other fast ; wind blasting is set to cool the hot sand , remove dust and strip the membrane so that fast speed of regeneration and top - grade used sand can be gained 主要工作原理是低速转动的底刮板推动物料在机盆内形成环流,中速转动的转子叶片既对砂子施以冲击力,又与刮板配合对砂子施以剪切力,使砂粒间快速接触和强烈摩擦,围圈设风带鼓风使热砂沸腾冷却除尘脱膜,从而达到再生速度快,回用砂质量好的目的。
The normal analytic technique was adopted to mensurate the basical nutrients such as total n , total p , total k , available n , available p , available k , organic matter , ph and so on . meanwhile , various techniques were employed to mensurate the soil dissoluble carbon , finally the technique of water saturating - h2so4 - agso4 - circumfluence - feso4 titration was used in this experiment 测定土壤的基本养分状况全氮、全磷、全钾、速效氮、速效磷、速效钾、有机质、 ph等采用常规分析法,对土壤可溶性碳的测定方法进行了多方面的探索,最后采用水提? h _ 2so _ 4 - ag _ 2so _ 4回流? feso _ 4滴定这一方法。
It shows that the adjacent synthetic jet flow field is affected by the phase - difference , amplitude and frequency of two actuators , and the synthetic jet is asymmetric and turning when they are working differently . the main reasons result with the asymmetry and the interaction between the two adjacent synthetic jets , leading to the formation of " low pressure closed circumfluence region " , which is also called entrainment field , and the synthetic jet turns to the region where the pressure is lower and the vorticity magnitude is higher 当两相邻激励器处于不同工作状态同时工作时,合成射流将发生偏转,其主要机理是由于两激励器吸入和排出流体流动不同,使得两列旋涡对不对称,在两列旋涡对之间存在“卷吸场”和压强梯度,从而引起旋涡对向低压侧和强涡量区偏转。
Our conlusion is : during the coruse of the nov in el - nino year ( start from the westerly anomalous ) to apr of next year , it is just the intensity of east asian monsoon that influents the sst variety in kuroshio region . the heat flux is the bridge links the two facts . and the gene which affects winter monsoon is the pea circumfluence 分析还显示影响黑潮海温异常的主要机制有:由赤道中太平洋西风异常而产生的pea遥相关、夏季太阳辐射的加强、低纬向高纬暖水输送的增加及黑潮自身海表水的辐合。
About the transducer between rotor and power source , the paper uses a cycloconverters , comprising 36 thyristors , and analyzes the control of circumfluence , the method of cosine crossing , the producing of trigger pulse , zero current detecting , commutating logic control and its mathematical model 对双馈电机转子侧所接变频器类型,本文也进行了对比分析,对选用的循环变流器的原理还作了进一步的分析,包括环流控制方法、余弦交截法原理、触发脉冲产生、零电流检测和换向逻辑控制等部分,并给出了其数学模型。
But the platform has some problems as follows : first , the seawater quality of the sea where the oil field is located is so special that it is difficult to make the treated seawater achieve the injection index . second , the supply of seawater injection of the oil field is more than the demand , and the surplus is drained directly to the sea by circumfluence that makes seawater resources , energy resources and medicament for seawater treatment waste . and third , it is very difficult for the pumps to realize constant pressure injection because there is no distributing room for seawater injection in the sea 但目前该平台所存在的问题是:由于油田所处海域海水水质特殊,使得处理后的海水难以达到入注指标;再者,目前的油田注水供大于需,经水处理工艺处理后的海水,其多余部分采取回流措施排海,造成水源、能源和水处理药剂的浪费;此外,由于海上注水无配水间分水,造成注水泵机组不能实现平稳增压注水。
