查询词典 bed

Numerical Simulation of Flow Field in Pulsating Fluidized Bed Under special entry conditions, the CFD is used to simulate the three-dimension fluidized bed with different oscillation intensity and frequency in order to research the effect of sound oscillation on flow field in the fluidized bed. The results indicate that the sound oscillation can make the distribution of the flow field more uniform and can promote the heat and mass transfer.

脉动流化床流场模拟在特定的入口条件下，应用计算流体力学技术对三维流化床在不同振动强度、不同频率扰动作用下的流场进行模拟，得到声波扰动对流化床流场分布的影响，结果表明声波振动可以使流化床内的流场分布更加均匀，促进热质传递。

According to drawing up isopach map of salt in The Kuche depression and isobath map of the top and bottom of salt bed, preliminarily determined the relationship between zhe distribution of the structure and thickness variation of zhe salt bed: the salt bed is relatively thin in the pocket basin, but thick in both sides of the structure belt.

通过编制库车坳陷盐层等厚度图及盐层顶、底面等深度图，初步确定了盐相关构造分布与盐层厚度变化之间的关系：盐层厚度在袖珍盆地较薄，而在两侧构造带厚度较大，盐层厚度较大的地区大致围绕袖珍盆地呈半环带状分布。

Results After the beginning of the railroad medical security systems reform at the February of two thousand and four, the freedom of patients in the selecting hospital increased, the effectual demand of health service changed, and part railroader patients run away to other hospitals with more competitive ability so that railroad hospital bed efficiency index descend suddenly even lower than the lower control limit. After this, the hospital bed vacancy caused by the outflow of railroader patients was occupied by nearby patients in the radius of hospital service gradually and the railroad hospital bed efficiency ascended correspondingly.

结果 2004年2月铁路医疗保障制度启动，病人选择性就医的自由度加大，病人的卫生服务有效需求发生了转移，一部分铁路医保病人流向了有较强竞争力的其他医院，使得医院病床工作效率值骤然下降，低于病床工作效率控制下限；此后，铁路系统内病人外流造成的床位"空缺"逐渐被医院服务半径内的其他病人占用，医院病床工作效率逐渐缓慢回升，至2005年5月已接近医改前病床工作效率值平均水平。

He deposited the articles of clothing on a chair, removed his remaining articles of clothing, took from beneath the bolster at the head of the bed a folded long white nightshirt, inserted his head and arms into the proper apertures of the nightshirt, removed a pillow from the head to the foot of the bed, prepared the bedlinen accordingly and entered the bed.
