In August,there are obvious changes among different treatments under soil water stressconditions. Vs, and Vs/Va obviously raised while Va reduced, and tissue water contentalso changed. Comparing with that in July, water content of leaves in differenttreatments in August decreased by 18.06%, 2.57%, 4.82% and 9.94%, respectively.In August and September, diurnal average Tr under different treatments (light,medium, heavy and no soil water stress conditions ) are 80.90 mmolh_2Om~(-2)s~(-1)、76.37mmolh_2Om~(-2)s~(-1)、65.46 mmolh_2Om~(-2)s~(-1)、42.11 mmolh_2Om~(-2)s~(-1) and 40.60mmolh_2Om~(-2)s~(-1)、33.92 mmolh_2Om~(-2)s~(-1)、30.44 mmolh_2Om~(-2)s~(-1)、23.29 mmolh_2Om~(-2)s~(-1),respectively. It shows that the Tr of Atriplex canescens leaves takes a tendency ofdeclining under long-term soil water stress conditions.

Just as I had set my Mast and Sail, and the Boat began to stretch away, I saw even by the Clearness of the Water, some Alteration of the Current was near; for where the Current was so strong, the Water was foul; but perceiving the Water clear, I found the Current abate, and presently I found to the East, at about half a Mile, a Breach of the Sea upon some Rocks; these Rocks I found caus'd the Current to part again, and as the main Stress of it ran away more Southerly, leaving the Rocks to the North-East; so the other return'd by the Repulse of the Rocks, and made a strong Eddy, which run back again to the North-West, with a very sharp Stream.
我刚竖起桅杆张好帜,船就开始向前行驶了。我发现四周水色较清,知道那股急流在附近改变了方向。因为,水急水则浊,水缓水则清,我知道那股急流在这儿已成了强弩之末了。不久我果然发现,在半海里以外,海水打在一些礁石上,浪花四溅。那些礁石把这股急流分成两股,主要的一股继续流向南方,另一股被礁石挡回,形成一股强烈的回流,向西北流回来,水流湍急。

The theories proposed by Wilson (1994) were adopted to describe the fundamental behaviors of temperature and variation of suction of soil. The Darcy's law and Pick's law described the flows and evaporation of water respectively. Some proposed assumptions including the characteristic curve of volumetric water content and hydraulic conductivity were only related to the suction of unsaturated soil. The coefficient of latent heat for water was a linear function of temperature; and the heat conductivity was calculated according to the equation proposed by De Vries.
对于土体的温度和吸力变化特征,采用Wilson提出的理论加以描述,在此理论中,分别利用Darcy和Fick定律描述水和蒸汽的流动规律,土水特征曲线和水力传导系数假定仅仅相关于非饱和土吸力,水的潜热系数是温度的线性函数,温度传导系数采用De Vries建议方程加以计算。

The previous researches have been done experiments mostly in the Water tank. In order to simulate turbulence of flow in river and research its characteristics, the characteristics of turbulence are studied by experiments in the water channel with ADV technique. The research results indicate that R.M.S. velocity linearly relates to the oscillating-grid frequency; R.M.S. velocity decays by power exponent relates to the distance from the grid midplane; and the relationship between the geometrical factors and the free movement space of water is direct proportion.
