This research was conducted in degraded rangeland at the southwestern edge of the Mu Us sandland, Yanchi county, Ningxia, the soil seedbank features and its relation to vegetation was analyzed using similarity analysis and ordination method, the results show that seeds within soil distribute mainly in 0~5 cm soil layer, less seeds in 6~15 cm soil layer in exclosed and non-exclosed rangeland, for seeds in exclosed soil, species richness and diversity index H are higher, while D is lower, exclosure measure, generally speaking, can increase plant species and amount of vegetation and seeds in soil, some annual plants, mesophytes and halophytes appears in the soil or surface.

以毛乌素沙地西南缘宁夏盐池县的退化草场为研究对象，采用相似性分析和排序方法对封育和未封育草场土壤种子库的特征及其与地上植被间关系进行了研究，结果表明无论封育区还是未封育区，土壤种子库中的种子主要分布于0~5cm的土层，6~15cm土层的种子数很少；封育区土壤种子库的物种丰富度大于未封育区，物种多样性则表现为H 值较大，而D值较小，总体上看封育措施可以提高地上植被和土壤中种子的种类和数量，一些一年生植物、中生植物和盐生植物开始出现在地面或土壤种子库中。

Objective To investigate the change of 24 h absorption, distribution and excretion of brick-tea fluoride in rats.

目的 观察砖茶氟在大鼠体内24 h吸收、分布及排泄的动态变化。

The results showed that the mutant contained high trehalose content and high cell survival rate kept even after 4 h 18 %vol alcohol treatment (no respiration deficiency existed), which indicated that high trehalose content could protect cells membrane and prevent DNA loss of mitochondria and exosmosis of intracellular materials.

结果表明，中性海藻糖酶缺失突变株细胞海藻糖含量较高，用18 %vol的酒精处理4 h后仍可保持高的细胞存活率，并且无呼吸缺陷型的出现，说明高海藻糖含量可以保护细胞膜，防止线粒体DNA丢失和胞内物质的外渗，与酵母的酒精耐性之间存在一定的关系。

The values of ΔH° and ΔG° indicate that the adsorption is a spontaneous exothermic process.

其ΔH°和ΔG°值表明该吸附反应是自发进行的放热反应

Methods Three-dimensional gels of type I collagen containing rabbit keratocytes were incubated in the presence of different concentrations of exotoxin A (0.1,1.0,10 mg·L-1),cultivated for 24 h at 37℃, the change of keratocytes in morphology was observed under the light microscope,and the amount of lactate dehydrogenase was measured by enzyme linked immunosorbent assay.

含兔角膜基质细胞（1×105·mL-1）三维胶原凝胶表面添加提纯的不同浓度绿脓杆菌外毒素A（0.1、1.0和10 mg·L-1）后，放入无血清MEM培养液中37℃培养24 h，采用光学显微镜观察培养的兔角膜基质细胞形态学变化，采用酶联免疫吸附法检测损伤的兔角膜基质细胞释放的乳酸脱氢酶含量。

Result: The inductivity of leaves was the highest about 87.5%, followed with the stem section and leafstalk; The inductivity of nutrient medium such as MS, B5 callus was higher than the ones like H, SH and the White callus amended one; It was found that low-grade Phvalue benefits the growth of callus. The experiment result showed that different pH showed little difference in quality. The best condition of culture was 25 ℃in temperature. Conclusion: The best culture condition for callus was the leaves as explantation.

结果：叶片的诱导率最高，为87.5%；茎段次之，叶柄较差；培养基MS，B5愈伤组织诱导率较高，达到了80%以上，高于培养基H，SH和改良White的愈伤组织诱导率；偏低的pH对愈伤组织生长有利，出愈率高，但从愈伤组织生长质量方面看，不同pH差异不明显；愈伤组织诱导最适温度为25 ℃。

We found that the permeability ratio and GMI ratio depend on external magnetic field, peaking at a transverse anisotropic field of H=0.4 kA/m.

并发现有效磁导率比随外磁场的变化，在各向异性场H≈0.4kA/m处出现了峰值，GMI效应也在此磁场的位置处出现峰值。

Baernstein[2] gave the conclusion by using Koebe function as the extremal function , Glenn Schober[6] studied the classes such as S, P, K, S* of H and represented these functions with integral formulations. Wang Jian[3] and others investigated the integral mean values. Our work is continuation of their work.

Baernstein首先在单位圆上讨论给出了以Koebe函数作为极值函数的结论，Glenn Schober对H中一些函数子类如S、P、K、S~*等作了研究，将这些子类上的函数用积分表达出来，王键结合Baernstein~*函数的定义及Glenn Schober的结论，定义了对称集的概念并得出了一些函数类在其上的积分平均。
