使转调

This abalone Xun Xun has managed to maintain the tradition of the original shape and tone, and increases the volume, the expansion of the range, and the chromatic scale to blow, it could be the transfer of musical instruments, ancient and mellow tone, low tragic, very Rich features.

这种九孔埙既保持了传统埙原有的外形和音色，又增大了音量，扩展了音域，能吹出音阶和半音，使它成为可以转调的乐器，而且音色古朴醇厚、低沉悲壮，极富特色。

In this system,the VVVF(variable voltage variable frequency) control method based on magnetic flux trajectory is applied.In the system,it is the target for the magnetic flux linkage polygon to be greatly approximate to the ideal magnetic flux circle.Considering such limitations as the low speed torque ripple,high speed real time and the working frequency of switching element,through the subsection synchronization control method by applying different numbers of magnetic flux linkage polygon for different frequency range,the perfect precision specifications for speed can be obtained.

系统采用基于磁通轨迹法的他控式变频调速方案，以磁链多边形尽量逼近理想磁通圆为目标，并考虑低速转矩脉动、高速实时性和开关元件的工作频率限制等约束条件，通过采用分段同步控制方式，在不同的频段采用不同的磁链多边形边数，使系统获得了优异的转速精度指标。

Based on the analysis of the stability of the nature tailless UAV, The control system of the tailless UAV is designed by using the classical control method and a time-based method is used that can tune up control law parameters automatically by virtue of optimizing.

为了使所设计的控制器参数较优，本文以滚转保持与控制模态为例，采用了一种带有时域约束的优化控制方法设计出这些回路的基本控制律参数，并针对各控制模态在频域内进行稳定性分析，证实了该调参方法在工程上可以得到很好的应用； 4。

It is important for AC timing field to combine the direct torque control and bushless double-fed motor.

把直接转矩控制技术应用到无刷双馈电机，可以使二者的优点得以结合，对于交流调速领域具有重要意义。

So the defocus quantity is calculated by detecting the image spot position offset and the front focus plane of the collimation lens can be adjusted on the first image of the theodolite.

该方法利用半反半透镜将准直物镜后的物光折转，采用双分离透镜将目标成像到CCD上，经视频驱动、放大电路、再经A/D转换后输入到微机进行图像信号处理，这样，通过检测像的偏移量求出离焦量的大小和方向，然后驱动调焦部件使准直镜的前焦点在经纬仪的第一像面上。

There is in folk music melody a phenomenon of "Five-Tone Multi-Gong Synthesis", in which the diao seems turning but really not so.

民间音乐旋律中存在着一种调似转非转的&五声性多宫综合&现象，这一现象的特点是在旋律发展过程中将不同宫的五声进行综合运用，使偏音具有它宫正声的意义。

The high smoothness, transfer and deposit real fine surface covering barely high density monlchamus layer, the little dot reproducibility; on the contrary, the ink layer that you want printed on the largening business card printing and membership card making pressure to the heel holdout, resulting in imprinted dot gain and deformation and other adverse effects, which in turn affect the image and color of normal again.

陡滑度矮，转印的不朱层名而且包围纸背的庞不小针孔，不朱层密度矮，小网不面表示性好；反之，则不朱层印不名，需增不小制卡和会员卡制作不不张辛，才能使不朱层不合座迁徙，造不败痕迹网不面增不小与变形等不良不败果，进而感化图像阶调与色彩的变态表示。

In recent years, the music workers carry out effective reforms to the traditional Hulusheng, developing a kind with ten pipes, changing the body with wood and adding a resonance box on the pipe, which not only expand the range to nearly two octaves, but also increase the volume, with the key characteristic of inflexion.

近年来，四川凉山的音乐工作者，对传统葫芦笙进行了较有成效的改革，研制出十管葫芦笙，笙斗改为木制，笙管上增加了共鸣筒，不仅使音域扩展到将近两个八度，还增大了音量，其最大特点是能够转调。

The development from simplex existence of three tuning systems to organic combination of three tuning systems is known as the twelve-tone-equal temperament with multi-frequency flexibility. The harmonious combinations between circle-of-fifths system and rhyme, just intonation and harmonic, and twelve-tone-equal temperament and inflexion, make up a new tuning system which takes full use of advantages of three tuning systems.

从三律的单一存在发展到现代三律的有机结合(即&复频弹性十二平均律&)，五度相生律与旋律美相映，纯律与和声美相映，平均律与转调美相映，复频弹性十二平均律综合三律之长，避其之短，构成一个新的律制，使三律融为一个自由变通的统一体，进入相对的自由王国。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
