Different from the routine trapeziform curve of frequency converting speed system, the motor's speed was adjusted according to exponential curve , and soft braking was realized by detent unit contained in the power module, enhancing the fluency and stability when running.

自动门的运行速度曲线与常用的梯形变频调速曲线不同，采用S形曲线对电机进行调速控制，以及采用自带缓冲制动单元的功率模块实现柔性制动，增强了自动门运行的稳定性和平滑性。

One of the great discoveries of the study is that the MSC can be used to analyze and describe the complex reactions that both phase transformation and sintering happened at same time. In addition, using both our five-parameter S-curve fitting and German's three-parameter curve fitting lead to very similar results and values of Qa. Most importantly, we cannot find satisfactory data to support the hypothesis that Qa varies linearly either with particle diameter or with initial porosity of the samples.

在利用主导烧结曲线模型分析六组实验数据过程中，发现主导烧结曲线具有拟合烧结与相变同时发生之能力，此拟合曲线中包含了四个反应，包括anatase与anatase的烧结、anatase与rutile的烧结、rutile与rutile的烧结还有anatase的相变，此四种不同的反应竟然可以只由一条主导烧结曲线描述其变化，是本研究重要的发现。

Modern ways of controlling acceleration and deceleration can be divided into the trapezoidal speed curve and the S-shaped speed curve.

通过对梯形速度曲线与S形速度曲线的比较，可知S形速度曲线在减小冲击和振动方面更具有优势。

Results indicated that according to the different newly increased cultivated land rate, land consolidation projects on the district or county level could be divided into four categories: land consolidation, cland consolidation and exploitation, land development and consolidation, land development. While according to the investment per unit area on newly increased cultivated land, it could also be divided into four categories: high investment, reasonable investment, partial low investment and low investment. Correlating curve type among the investment per unit area in newly increased cultivated land, average annual growth rate of GDP and average annual growth rate of per capita GDP was a compound one. Correlations among newly increased cultivated land investment per unit area and annual growth rate of per capita GDP, annual growth rate of per capita GDP and other economic development indexes showed an "S" changing tendency curve.

Experiments were carried out to verify the static model. Experimental results show that the experimental curve matched well with the simulated curve, and there was certain error between them (maximal static error is 0.035 rad). The error cause was analyzed. Then the experiments were carried out to measure the dynamic performances of the side-sway joint. Experimental results show that the step response time of the joint was about 2 s steady value's tolerance zone ?
