1. In low dosses, its pharmacological effects resemble those of propranolol.
小剂量时其药理作用与心得安相似
2. Then, flecked mattesses were extended on the dosses. Arms and toes wearing ratty socks could be seen everywhere in the porch.
之后，铺位上纷纷铺起污迹斑斑的列车床垫，走廊里顿时到处都是胳膊和露在外面、穿着破袜子的脚丫子。
3. Afterwards, flecked mattesses were extended on the dosses. At once arms and toes wearing ratty socks exposed could be seen everywhere in the passage.
之后，铺位上纷纷铺起污迹斑斑的列车床垫，走廊里顿时到处都是胳膊和露在外面、穿着破袜子的脚丫子。
4. In the chamber, narrow space is left between the dosses below and above, every inch of which has been taken up by Russian workers and clamorous Turkomen.
车厢单间内，上下铺位间的空间狭窄，上面全都挤满了俄罗斯工人和成群唧喳不停的土库曼人。
5. The YW(subscript 25G) train corn partments were studied, and passengers and several kinds of barriers (including desks, racks, dosses, seats) were taken into account for airflow. The k-ε turbulence model was applied for numerical simulation of indoor fluid flow and age of air, and the air exchange efficiency was obtained.
笔者以YW(下标 25G)型空调硬卧列车车厢为研究对象，在物理模型中考虑了旅客以及车厢内各障碍物（包括边桌、行李架、床铺、折座）等对流场的影响，采用k-ε湍流模型及数值模拟的方法，对硬卧车厢内流场及空气龄的分布变化规律进行研究，从而得到车厢内的换气效率。
