Third, the fact that most of the Lao Tse interpreters then were Confucianists points to the main role Confucianists played in the continuation of Laoist school then.

第三，明代注《老》者中，以儒者为多，《老子》书似乎正在逐渐淡出道门人士的视野，儒者成为延续老学学脉的主力。

The results show that the frequency characteristic corresponds with vortex structures; the detail and approximate characteristics of signal are reflected by wavelet coefficient at different scales; the coefficient map of continuous wavelet transformation reveals the self-similarity of the signal.

采用傅里叶变换和小波变换技术，实现了混合层密度脉动信号的频谱与多分辨率分析，结果表明：信号的频域特性与流场的涡结构相对应，不同层面的离散小波系数反映了不同尺度下信号与图像的细节和平滑近似特征，连续小波变换系数图定性的反映了信号的自相似特征。

At the same time, this paper set up a three-dimensional model, then analyzed and calculated of conducting cylinder heat transmission through software MATLAB and COSMOS. A mathematic model initial injection pulse-width is set up according to the quality's continuousness and the energy conservation law.

根据气体状态方程和能量守恒定律分析建立了基本喷油脉宽的数学模型，并运用在国产125ml摩托车汽油发动机上，仿真得出此发动机电控汽油喷射系统的初始喷油MAP图。

Onlyadjusting outside resistance and the capacitance value, not only it may obtain the contravariant frequency which we need, moreover it may adjust the dead time, like this wemay realize to adjust the pulse width neatly.

调节外接电阻和电容值，不但可以获得所需的逆变频率，而且可以调节死区时间，这样可以实现对脉宽、周期的灵活调节。

We use integrated chip TL494 are the master control chips, by the MOSFET tube constitution inversion electric circuit, has realized the contravariant system's pulse-duration modulation.

我们采用集成芯片TL494为主控芯片，以MOSFET管构成逆变电路，实现了逆变系统的脉宽调制。

The main circuit adopts the threephase bipolarity contravariant bridge circuit composed of power bipolar-transistor.

其逆变器依据正弦波脉宽调制技术，主电路采用三相双极性逆变桥式电路，逆变管采用电力场效应晶体管。
