time-phase

An investigation was conducted on the hydrological underlying surface for rain-induced floods from Sanmenxia to Xiaolangdi in the mid-lower reaches of the Yellow River by means of the multiple time-phase, high-resolution remote sensing data of Landsat TM/ ETM~+.

以2002年4月18日LANDSAT TM/ETM+多时相、高分辨率遥感数据为主要数据源，对黄河三门峡至小浪底区间暴雨致洪水文下垫面进行调查。

Methods: The temperature of testis in rats was reduced to-10 ℃ to observe its morphological structure changes of testis germ cell, Leydig cell and Sertoli cell and detect the level of sexual hormone at different time-phase following temperature reduction.

方法：将大鼠睾丸温度降至-10℃，在降温后不同时段采用光镜、组织化学方法观察睾丸生精细胞、间质细胞、支持细胞的形态学变化，并测定血清性激素水平。

Secondly, according to the problem of getting information of phase from speckle fringes image, we make further researches on time-phase technology, and presented a preliminary idea about designing a phase shifter based on SCM.

其次，为了能够从散斑条纹图中提取出位相信息，对时间相移技术进行了深入的研究，并初步提出了一种基于单片机控制的相移器的设计思想。
