In order to distinguish between the physical basis of the HH equations, in terms of the flow through the axon membrane of sodium and potassium ions, on the one hand, and the phenomena of excitation above a threshold value of stimulus, and propagation along the axon, on the other, it seemed that it would be useful to simplify their equations in order to isolate these properties from each other.

为了区分的物理基础的螺杆菌方程，从流经轴突膜的钠和钾离子，一方面，与上述现象的激励的阈值的刺激，并沿轴突传播另一方面，它似乎将是有益的简化方程，以孤立这些财产彼此。

A large amounts of imformation about the systerm's vibration characteristic are presented. Some dynamic behaviors caused by gyroscopic moment, oil while in bearing and unaligned shaft line are studied.

During dehydration, the tolerance of wampee axes to desiccation which was analyzed as germination percentage, vigour index, and rate of electrolyte leakage, and activities of antioxidant enzymes gradually decreased, the content of malondialdehyde , progressively increased.

黄皮种子离体胚轴在脱水过程中，胚轴的萌发率、活力指数、电解质渗漏速率，超氧化物歧化酶、过氧化物酶和过氧化氢酶活性逐渐降低，膜质过氧化产物MDA的含量不断增加。

When the undrawn films were annealed atthose temperatures, the morphologies in the lamellar crystals had change. WAXDand iR studies shown that the crystallinities incrcand, dimensions in (002) and(020) normals increased while that in (200) fold had slight decreases. The rela-tionship between the orientation of the drawn UHMWPE gel-films and the struc-ture changes and the optimum drawing temperature had been disscussed.

通过IR及X－ray衍射等方法研究发现，拉伸前用不同温度退火处理后，凝胶膜的片晶微结构产生明显变化，在对应于超高拉伸温度范围内，其结晶度增加，微晶的c和b轴方向尺寸变大，而a轴方向的尺寸减小，从理论上对这一变化过程作了考察，并讨论了超高拉伸取向性与这些结构变化的关系以及可超拉伸取向性的最佳温度范围。

By employing coordinate transformation, the overall generalized displacement vector relevant to the motion of pad and axle journal is converted into axle journal displacement vector in a local motion coordinate system, and the oil film force in a partial motion coordinate system is obtained by solving the dynamic characters of a fixed bush bearing.
