步幅

In this paper, much energy has been placed on phosphate concretion re search which host in black shales of Dou Shantuo Fm. and Nu Titang Fm、 Research contents include mineralogy, petrology and geochemistry character istics of phosphate concretions. Element distributive characteristics are ana lysed using Synchrotron Radiation techniques. Additionally, sulfur isotopes of francolite and their significance are discussed in this paper. The results are as following

本文开展了晚震旦世陡山沱组以及早寒武世牛蹄塘组两套黑色页岩中磷结核的研究，对产于这两套黑色页岩中磷结核的矿物组成、地球化学等方面开展了研究，首次运用了同步幅射X-荧光探针对结核内元素的分析特征进行了分析，同时还测定了磷的硫同位素并讨论了其意义，所得出的结果简述如下

Without hurrying, the steps are lengthened to the utmost as a result of great impulsion from the hindquarters.

在不急促的情况下，来自於后躯强有力的前进气势，使步幅最大限度地伸长。

Further analysis revealed that the sum of stride length and vertebral rotation was greater for the vaginally orgasmic women.

进一步分析表明，有阴道性高潮经历的女性，其步幅大小和脊柱扭转程度较大。

If they can just keep this last stride into the final oxer.

如果他们可以将最后的步幅调整到最后的栏

How Do I Wear My Pedometer and Set My Stride Length?

我如何穿我的计步器和设置我的步幅？

The train leaves promptly at 7:30, and he has to pick up the pace to get there.

火车及时地离开在7：30，并且他必须拾起步幅到那儿。

From time to time, I would pick up the pace and go ahead of some of the them.

常常，我会拾起步幅走到一些人前面。

The finding reveales that the last stride of run-up, the distance between the prop foot and the ball, the back swing range of the thigh as well as the folding range of the shunk which can be used as standards to test of instep inner edge place-kick kill play an important role in the teaching and training of football. These standards are easy to operate and can bring about a striking effects.

与传统的教学定义相比较，助跑最后一步步幅、支撑脚与球的距离及大腿后摆幅度、小腿折叠幅度在足球教学与训练中有其独特的价值，完全可以作为评价脚背内侧踢球技术专项水平的指标，且方法简单、效果显著、可操作性强。

Finally, it has been proved that a step learning function, which satisfies the condition of LMS algorithm, could make network weight converge with probability 1 to the feature vector.

并证明了SOFM网络的学习存在一表征特征矢量的稳定解，最后证明了一个满足LMS随机逼近收敛算法条件的步幅函数可使网络权值以概率1收敛于特征矢量。

After comparing with previously report, conclusion was as follow: when players use take-off spike movement by single-foot, the strides should increase progressively after observing the ball's direction, and raise the height of jump by getting faster horizontal and vertical velocity of body gravity. In order to avoid increasing the time of take-off, the body gravity is inadvisable to drop so much. In air motion period, player's movement of arm swing will influences the time of spike, if we emphasize the quick offensive, it should reduce the movement of arm swing to decrease the time of spike. When spiking, the joint of elbow should flex by a little range to make forearm powerful.

经由本实验结果与过去研究比较后得到以下结论：选手在执行单脚起跳扣球动作时，助跑的步幅宜在观察球的动向后，采取递增的方式助跑，并加快身体重心水平速度及垂直速度，以提高起跳高度；起跳期起跳脚踏入瞬间身体重心不宜大幅度的下降，以避免增加起跳所花费的时间，影响扣球的节奏及战术的执行；空中动作期时，选手的挥臂动作会影响击球时间，若要强调快速的进攻节奏，宜减少扣球的挥臂动作，以降低完成扣球所需的时间；而击球瞬间肘关节宜保持小幅度的弯曲，以发挥前臂的力量和速度。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
