弓

Based on Bezier curve continuance of first－order and second－order derivative, the characteristic vector equation of two Bezier curve is presented in point of intersection. The algorithm is not only of high accuracy with all of the interpolated points being on the curve theoretically, but also of very high speed in the real－time interpolation processes. The interpolation velocity does not change and the segment tolerance of interpolation can be control by selecting the parameter in cerement rationally every time.

为保证两段Bezier曲线在连接点处一阶导数、二阶导数连续，导出了两段Bezier曲线特征向量应满足的关系方程，Bezier插补法不仅在理论上可使所有的插补点落在曲线上，而且实时插曲补速度高，每次插补时可合理地选择参数增量，能使插补速度保证不变，也可控制弓高误差。

Flower pull the basic moves, because is located in the mountains, high mountain坡陡, gradeability would move the high leg lift, body lean, downhill is restrained out of state knees, body slightly Yang, thus men dance to "play to跋, knee should be bent, step to stability,"women dance to" into to bow, back to D, feet outside the charge-off."

拉花的基本动作，因地处山区，山高坡陡，爬坡则要迈步高抬腿，身体前倾，下坡则是双膝出于拘谨状态，身体稍仰，因而男性舞步为"起要跋，膝要屈，踩要稳"，女性舞步为"进要弓，退要丁，脚外撇"。

It was luxuriously trimmed, with leather upholstery and chrome 'bows' in the headliner to simulate the ribs of a convertible top.

这是豪华修剪与真皮内饰和镀铬，'弓'在车顶来模拟一车顶的肋骨。

They washed their hands and took up the barley-meal to sprinkle over the victims, while Chryses lifted up his hands and prayed aloud on their behalf.

然后，他们洗过双手，抓起大麦。克鲁塞斯双臂高扬，用洪亮的声音朗朗作祷：听我说，银弓之神，卫护克鲁塞和

And the chub are not alone.

弓背鮭并不是唯一的受害者。

The humpback chub, for example, thrived in the rust-red waters of theColorado.

比如在科罗拉多红锈色的水中繁衍的弓背鮭。

Without the cloudy water the chub became vulnerable.

没有了浑浊的水，弓背鮭极易受攻击。

At first sight, itlooked as if the reason was that the chub were being eaten by trout introducedfor sport fishing in the mid-20th century.

初一看，好像是因为弓背鮭被20世纪中为了钓鱼运动而引入的鳟鱼大量吃掉了。

Steve Gloss, of the United States'Geological Survey, reckons that the chub'sdecline is the result of their losing their most valuable natural defence, theColorado's rusty sediment.

据美国地质勘探局的史蒂夫格劳斯估算，弓背鮭的减少是由于它们失去了它们最有价值的自然防卫——科罗拉多河里的红锈沉积物。

The chub were well adapted to the poor visibilitycreated by the thick, red water which gave the river its name, and depended onit to hide from predators.

弓背鮭非常适应浑浊红色的河水中的低可见度，并可以借以躲避天敌。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
