Numerical simulations were done for a bistable latch valve of the system by FLUENT, and three groups of datum for different fluids were obtained with the same effective exit sectional area. Besides, a static mathematic model for the electromagnetic valve was established based on the obtained datum. Secondly, the motion of the valve spool was realized by UDF file in FLUENT. Three kinds of motions, uniform, acceleration and motion driven by the coupling effect of the liquid resistance and the electromagnetic force, were calculated and compared. The dynamic characteristic of the electromagnetic valve was obtained by analyzing the relationship of the mass flow rate of the inside flow field of the electromagnetic valve, the change of the drop pressure of the passageway of the valve, and motion time.

Healthy volunteers participated 6 experiments that were designed to test the sensory conflict theory of motion sickness, to observe the effect of the outside proprioceptive input on motion sickness and to make sure the influence of motion sickness susceptibility, automatic nerve activity and breed on experimental nausea and vomiting. The results were as follows: 1. Different intensity of visual and vestibular sensory conflict effected the onset of vection and rotation toleration time and the symptoms of nausea and vomiting, the more intensive of confliction, the more quickly onset of vection, the more short rotation toleration time, and the more serious symptoms of nausea and vomiting.

本研究针对上述问题设计了6个实验，以200名健康成年志愿者为被试，以转椅和转鼓作为诱发实验性晕动的装置，采用恶心评定量表、恶心问卷和晕动敏感史量表及自我运动错觉和旋转耐受时间为指标，旨在考察：（1）实验性恶心、呕吐症状的时间变化规律；（2）不同强度感觉冲突、不同体位因素对实验性恶心、呕吐的影响，验证晕动的理论假设；（3）晕动敏感史差异、人格因素、种族因素与实验性恶心、呕吐的关系。

The Chinese machines converted rotary motion into longitudinal motion, because they started with the water-wheel, whereas the European machines converted longitudinal into circular motion, but in all other respects they were identical.

中国机械把圆周运动转换成直线运动，因为一开始使用的就是水轮；反过来，欧洲机械则把直线运动转换成圆周运动；两者在其余各方面基本上完全一样。
