As a result, high sensitivity spin valves can be achieved by choosing underlayer material with proper surface free energy. Moreover, a new type of double exchange-biased SV with two ferromagnetic layers exchange biased in opposite directions by two antiferromagnetic layers are proposed. Since the modified SV expanding the switching window of antiparallel state, it causes fabricating the SV more flexible, and especially for the SVs, in which enough large exchange coupling can`t be realized at some fabricating conditions.

Two IF peaks correspond well with two resistance peaks. Combing the results of electric and magnetic measurements, we think the high temperature IF peak corresponds to a transition from paramagnetic rhombohedral to ferromagnetic rhombohedral, and we can explain it with mechanism of double exchange. Whereas the low temperature IF peak is complicated, at which no apparent magnetic transition appears. We interpret it as a combination of a lattice distortion caused by a phase transition from ferromagnetic rhombohedral to ferromagnetic orthorhombic and a phase separation separating out an ordered ferromagnetic insulator polar phase at low temperature.
两个电阻峰与内耗峰出现的位置有较好的对应关系，结合磁化率测量的结果，我们定性的解释高温电阻峰起因于顺磁斜方相到铁磁斜方相的转变，是由磁性转变所引起的，符合双交换机制；而低温电阻峰情况较为复杂，无明显磁性转变，不能用双交换机制解释，被理解为由两方面的因素所致：即从铁磁斜方相到铁磁正方相的转变所引起的点阵畸变；低温下相分离所产生的铁磁绝缘体极化子有序相的综合结果。

Seven grapevine cultivars originated from different regions, i. e.'Carbernet Sauvignon'and'Queen of Vineyard'(two members of the Western Europe Cultivars Group), 'Rizamat'(a member of the East Cultivars Group), 'Red Double Taste'(a hybridized cultivar from Vitis vinifera L. and V. labrusca L.), '1103Paulsen', 'Red Globe'and'Autumn Royal'(two new hybridized cultivars between cultivars groups which were warmly planted in recent years) were selected. After different drought stress, a combined measurement of gas exchange and chlorophyll fluorescence was conducted to evaluate the effects of drought stress to photoinhibition, as well as the role of photorespiration and xanthophyll cycle in photoprotective mechanism. After photorespiration and xanthophyll cycle were separately inhibited, the complementary effect of these two photoprotective pathways was discussed. Detached leaves of different grapevine cultivars, i. e.'Cabernet Sauvignon', 'Cabernet Franc', 'Merlot', and a rootstock, '1103Paulsen'were selected as materials, and photoinhibition degree, photorespiration activity as well as its photoprotective function under drought stress were studied. The results are as follows: 1. Under the same drought stress treatment, different photoinhibition degrees formed in different grapevine cultivars.

Gaomiaozi bentonite has high Na~+-monmorillonite content and liquid limit, great cation exchange capability and specific surface area, which is character by low permeability, high dilatability and good heat conductivity. For high suction, water content does not change so clearly with suction, so there is no significant difference of soil-water properties between unconfined and confined conditions. For lower suction, water content under unconfined conditions will change sharply with decrease of suction while under confined conditions it changes smoothly. The dilatability of bentonite under unconfined conditions is mainly from the swell of inter-aggregate pores, which leads to the forming of aggregates. Under unconfined conditions, pores distribution in bentonite becomes uniform. Under unconfined conditions, volume change behavior can be explained by diffuse double layer theory with a dry density of 1.7g/cm~3, but the prediction error will increase when suction decreases.
内蒙古高庙子钠膨润土蒙脱石含量较高，阳离子交换容量和比表面积较大，液限较高，具有低渗透性、高膨胀性和良好的导热性能；高吸力范围内，含水量随吸力的变化不大，自由和侧限状态下土水特征无明显不同；在低吸力范围内，自由状态下含水量随吸力的降低产生突变，侧限状态下含水量随吸力的降低变化较为平缓；自由状态下膨润土的膨胀主要来自于集合体间孔隙的膨胀，从而形成了明显的集合体结构体特征；侧限状态下，膨润土的孔隙出现了均质分布特征；双电层理论能较好地解释干密度为1.7g/cm~3的高压实高庙子膨润土在自由膨胀条件下的体变特征，但随着吸力的减小，两者之间的误差有增大的趋势。
