查询词典 osmotic

The osmotic coefficients and saturated vapor pressures have been calculated at the different temperatures .The experimental values of the osmotic coefficients for the Li_2SO_4-H_2O system were consistent with the values in the references. The results revealed the rules of the changing in osmotic coefficients and saturated vapor pressures with ion strengths and the molality fractions of Li_2B_4O_7 at different temperatures. The isopiestic equilibrium molalities were correlated by using the modified and the extended Zdanovskii rules for non-ideal mixtures, and obey well the Zdanovskii rules. The ion interaction parameters of Pitzer model have been determined by using the two methods for Li_2SO_4-Li_2B_4O_7-H_2O at 298.15K system.

The eco-physiological characteristics of drought endurance of Pinus sylvestris var.mongolica were studied under different climatic regions, soil water and leaf water condition.Furthemore,the response and adaptability of trees to water stress was done.The below showed the results. 1 The parameters of drought endurance of P. sylvestris var. mongolica was measure and studied by PV technology in the subhumid, semiarid and arid regions The results indicated the osmotic potentials at water saturation condition and at the initial loss turgor decreased as the climatic drought degree increased,and related linearly with the climatic moisture index.It was proved that the drought endurance of P. sylvetris var. mongolica was varible and the elevation of the osmotic adjust capability was a main way to the adaptation of trees to the drought climatic environment.

本文研究了樟子松(Pinus sylvestris var.mongolica)的主要耐旱生理生态特征在不同地区、不同土壤水分状况和叶水分状况下的变化，进而研究了樟子松对水分胁迫的反应和适应，结果如下： 1 应用 PV 技术对半湿润区、半干旱区和干旱区樟子松耐旱性指标测定研究指出，水饱和总体渗透势和初始失膨点总体渗透势随着气候干旱程度增加而增加，与气候湿度指标呈直线相关，证明了樟子松属于耐旱性可变的树种，渗透调节能力增加是其对干旱气候适应的主要途径。

Leaf turgor loss point osmotic potential and saturation osmotic potential during the dry season were both significantly lower in all the three species, indicating a strong osmotic adjustment in adaptive to seasonal drought.

Before fissuration, osmotic adjustment occurred by the addition of solute to cells and decreasing the loss of water in the body, so that it could maintain normal turgor pressure during drought. After fissurate growth, turgor pressure was maintained by higher cell and tissue elasticity lower ε(superscript max and by osmotic adjustment for normal plant development in dry conditions and to avoid dehydration under water stress during the drought period, but it also became more sensitive to water stress. The ability to maintain turgor pressure varied from strong to weak during the period before, during and after fissuration. Fissurate growth decreased the ability of P. mongolica to maintain turgor pressure and led to changes in walls related to drought tolerance.

结果表明：1未劈裂绵刺主要通过增加细胞内溶质，减少细胞内的水分丧失来进行渗透调节，从而在干旱胁迫下能够维持正常的膨压。2己劈裂绵刺通过渗透调节和高的组织弹性两条途径来共同保持膨压，以抵抗不良的生存环境；同时对环境水分胁迫具有较高的敏感性。33种状态绵刺保持膨压的能力由强到弱依次为：未劈裂绵刺、正在劈裂绵刺、已劈裂绵刺。4劈裂的发生导致绵刺保持膨压能力的降低，同时耐旱方式和途径发生了变化。

NaCl and iso-osmotic PEG had inhibitory effect on the germination of two halophytic seeds, and the inhibitory level of PEG was greater than that of iso-osmotic NaCl. Inhibitory effects of NaCl and water stress mainly showed lowering the seed germination rate, delaying initial time of seed germination and extending the time of seed germination.
