The heart rate, respiration, blood pressure and peripheral oxygen saturation (SpO2) of pre-anesthesia, post-anesthesia, during operation and after analepsia in every group were detected. The narcotism was evaluated by Ramsaymin grading method and the related adverse reactions such as cough, restlessness, harmful memory, and abdominal pain after operation were recorded.

选取在兰州大学第一医院普外二科ERCP诊疗中心行治疗性ERCP患者1 660例，分为静脉镇静、镇痛组（n=800）和常规镇静、镇痛组（n=860），观察各组患者麻醉前、麻醉后、术中、麻醉清醒后的心率、血压、呼吸和血氧饱和度的变化，并应用Ramsaymin分级法评估麻醉状态，记录患者术中呛咳、躁动、患者对手术过程有无不良记忆、术后腹痛等相关不良反应的发生。

The system is controlled by continuous review installation stock policies. This paper presents an improved approximated method that the leadtime demand of warehouse is approximated by the normal distribution, and the leadtimes demand of retailers are approximated based on negative binomial distribution.

论文给出改进的近似方法，即用正态分布近似分销中心提前期内需求的分布，用更符合实际的负二项分布近似零售商提前期内需求分布，从而建立了二级分销系统期望总成本近似模型。

Then, using the second-order central difference to discretize the time derivative of the displacement, and applying the quadrature formula to the mass matrix, a fully discrete lumped mass Morley element method i...

然后利用中心差分格式离散时间方向的二阶导数，再利用适当的求积公式得到薄板弯曲问题的集中质量Morley元全离散格式。

Effects of Coriolis force were analyzed with the three dimensional simulations and the following conclusions were drawn: The tangential component of Coriolis force induces cross stream secondary flow in the form of two-cell pattern,while the radial component of Coriolis force decelerates and accelerates the cent...

计算结果表明，切向哥氏力推动了通道截面内的双涡二次流，径向哥氏力则使得近侧壁流体加速和中心流体减速。换热计算结果从定性趋势上吻合公开文献中的实验现象，反映了旋转附加力的基本影响规律。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
