Another way of stating this same relationship is to say that the length of the string is equal to an integral number of half wavelengths.

这种关系的另一种描述是，线的长度应等于半波长的整数倍，即是线的两个固定端正好为驻波的波节。

Methods In 12 fresh and 4 old mallet fingers.the broken tendons were sutured with double metal neddle and double button Bunnell''s suture.Matress suture using3-0 nylon suture were added.The suture tension maintained the DIP joints in extension of 10～20 degrees.No external fixator was used.

对12例新鲜锤状指、4例陈旧锤状指，用Bunnell带双金属针双钮扣肌腱缝合线缝合肌腱断端，即利用缝合线本身张力固定远节指间关节于过伸10～20度位，断端用3-0无创尼龙针线行褥式缝合，术后不用外固定。

Taking cydid gear-pin rail chainless traction mechanism of MG375W as an example, make theoretical deduction for the profile and the kinematic characteristics of the cycloid gear , and make simulation analysis for some different engaging positions by computer.

以MG375W采煤机的摆线轮与销排无链牵引机构为例，进行了摆线轮齿廓特性及运动特性的理论推导，对不同的啮合工位进行了计算机模拟仿真分析，得出了中心距及节距发生变化引起啮合传动特性的变化规律。

Inflorescence terminal, composed of several to many racemes inserted digitately or along a short axis; racemes elongate with many spikelet pairs, hairy, fragile, sessile and pedicelled spikelets of a pair similar, pedicelled often slightly narrower, both fertile; rachis internodes linear, ciliate along angles; pedicels resembling internodes, usually slightly shorter and more slender.
