Uniform motion can, however, never be realized; a stone thrown from a tower, a cart pushed along a road can never move absolutely uniformly because we cannot eliminate the influence of external forces.
可是匀速直线运动是永远不能实现的,从塔上抛下石子,在平路上推动车子都决不能绝对匀速地运动,因为我们不能完全消除外力的影响。

It shows that the FE method of tireanalysis under driving state and the method dealing with large slip frictionalcontact problems are correct and reliable. The properties of tires under steady cornering state are studied with FEmethod and experiment. Based on the presented contact solution algorithm, a FEmethod is carried out to analyze the properties of tire under steady corneringstate via imposing slip-rolling-constraints on tire bead nodes which contact therim, and the modules are programmed. The mechanical properties anddeformation of tire under pure steady cornering state and steadycornering-driving state are analyzed, and the results show good agreement withthe experimental data.

Methods Animals were randomly and equally divided into five groups: saline control group, positive drug control group, low-dose, medium-dose and high-dose crocetin group. Animals were anesthetized with urethane (1.2 g/kg), then followed by the perfusion of aconitine (10 μg/mL) through caudal vein in rats, or of ouabain (9 μg/mL) through external jugular vain in guinea pigs in a constant velocity of 0.1 mL/min, and the emergence time of ventricular fibrillation, ventricular extrasystole, ventricular tachycanlia and cardiac arrest were then detected and recorded. The recorded time was then translated to the cumulated amount of aconitine and ouabain. Experimental arrhythmia was induced by rapid injection of 4% CaCl2 (140 mg/kg), and the emergence time, persistence time, incidence and death of arrhythmia after the administration were observed.

I point out that mechanics does not provide adequate foundation for the description of all natural phenomena. We should have a new understanding that in the 'change of location' of the same event of inertial system there exist two different reference systems that are mutually in uniform rectilinear motion. This new understanding will avoid the puzzle brought about by physicists' obscure yet obdurate conception as to which of the two mutually uniformly moving reference systems is not related to the inertia reference system.
我指出力学为一切自然现象描述所提供的基础是不够充分的,重新认识惯性系的同一事件"位置的改变"存在着两个互相匀速直线移动着的两种不同参考系,可以避免物理学家们模糊、执着地认为惯性参考系究竟是用两个互相匀速移动着的参考系中哪一个无关所带来的困惑。
