This paper makes further research on the error,caused by use of a single step or a variable step of Runge Kutta to solve the Euler equation of quaternion method, find that the large error results from cumulated error with single step, and when using the variable step,the cumulative error is less.

结果表明，定步长时有很大的累积误差，单位四元数的"单位"性不能得到满足，而变步长有明显的改观，对一般的飞行模拟状态，都能得到较好的模拟结果，可以在实际中使用。

So, others support the cursorial hypothesis (eg, Burgers and Chiappe 1999 ) and suggest that these ancestors used their long, powerful legs to run fast with their arms outstretched, and were at some point lifted up by air currents and carried into flapping flight.

因此，其他支持cursorial假说（例如，汉堡和chiappe 1999年）和表明，这些祖先用他们的长期，强大的腿跑得快，与他们的武器outstretched ，并在一些点，取消了由气流和进行到扑飞行。
