The spatial-temporal distribution of NPP along NECT and its response to climatic change were also analyzed. Results showed that the change tendency of NPP spatial distribution in NECT is quite similar to that of precipitation and their spatial correlation coefficient is up to 0.84 (P.01). The inter-annual variation of NPP in NECT is mainly affected by the change of the aestival NPP every year, which accounts for 67.6% of the inter-annual increase in NPP and their spatial correlation coefficient is 0.95 (P.01). The NPP in NECT is mainly cumulated between May and September, which accounts for 89.8% of the annual NPP. The NPP in summer accounts for 65.9% of the annual NPP and is the lowest in winter. Recent climate changes have enhanced plant growth in NECT. The mean NPP increased 14.3% from 1980s to 1990s. The inter-annual linear trend of NPP is 4.6 gCm^(-2)a^(-1), and the relative trend is 1.17%, which owns mainly to the increasing temperature.

结果表明：(1)NECT样带植被NPP的空间变化趋势同降水量的空间变化十分相似，由东到西逐渐降低，二者在空间上的相关性达到了0.84 (P.01)，说明NECT样带的植被NPP在空间分布上主要受水分趋动：(2)NECT样带植被NPP的年际变化主要是由各年份夏季NPP的变化造成的，夏季对NECT样带植被NPP的年际增长贡献率最大(67.6%)，二者之间的相关性达到了0.95 (P.01)；(3)NECT样带的植被NPP积累期主要发生在5-9月份，这5个月的NPP占了全年NPP总量的89.8%，整个夏季（6-8月份）的NPP占了全年的65.9%，冬季（12-2月份）的NPP最低，基本为0；(4)近19年来的气候变化促进了NECT样带的植被生长，从1980年代到1990年代，NPP显著增加，年代际相对增长率为14.3%，平均年际绝对增长趋势为4.6 gCm^(-2)a^(-1)，相对增长趋势为1.17%，这主要是由温度升高引起的。

On the basis of dual porosity theory,the well test interpretation model which considers the variation of krg versus the volume of liquid is also established and resolved by the implicit method numerically.

摘要通过分析凝析气藏的相图，建立了凝析液饱和度随压力降的变化规律，并回归得出了相应的公式；同时通过对气体压缩因子、黏度随压力、温度的变化，建立了这些参数和无因次压力的关系；在双重介质地层假设的基础上，建立了在试井过程中凝析气相对渗透率随凝析液饱和度变化的凝析气藏试井解释数学模型，采用隐式迭代的方法进行了求解并进行了参数敏感性分析；结果表明：凝析液的饱和度对凝析气藏试井的压力及压力导数曲线有着很大的影响，早期由于凝析液的析出，阻碍了气藏的流动，导致压力及压力导数曲线上升；在凝析液饱和度达到峰值之后，随着凝析液的挥发，凝析气的相对渗透率逐渐恢复，压力及压力导数曲线又回归到正常的径向流位置；由于裂缝和基岩之间的压力差，使得裂缝弹性储容比在测试过程中发生变化，进而影响了压力及压力导数；窜流系数和裂缝弹性储容比的变化决定了窜流段发生的早晚和程度；而基岩中气体黏度的变化使得窜流的发生稍微滞后。

Results There was no obvious change in the ulstrasonographic characteristics and the pathology of the control group.The diameters,internal echo,the continuity of internal linear echo and epineurium changed correpondingly with time of compression in different model groups.

结果声像图表现：对照组与卡压前正常神经未见明显改变，各卡压组高频超声下均可观察到相应声像图变化，随卡压时间的延长，卡压两端内径逐渐增粗，内部回声逐渐减低，内部线性回声连续性差，神经外膜逐渐增厚。

Because of the regional difference of soil and climatic conditions, the division of 4 stages of soil moisture circulation is not all the same between different areas; the soil moisture dynamics between different dry farming areas in the Yellow River Basin is contrasted in this report. The results indicate that soil moisture increases gradually from dry semi-arid area to semi-arid area, dry semi-humid area and semi-humid area, and the high value district generally appears during soil moisture resuming period in rainy season or soil melting period. While the low value district appears at the stage of fast evaporation in spring or slow evaporation in autumn; in views of vertical changes of soil moisture, it is showed that the variation range of upper lays is larger than that of lower among the different dry farming areas in the Yellow River Basin.

由于各区域之间土壤、气候条件的差异，各地土壤水分循环4个阶段的划分也不尽相同；黄河流域不同旱作类型区土壤水分动态变化比较结果表明：就季节变化而言(来源：A70b0B0bC论文网www.abclunwen.com)，由半干旱偏旱区→半干旱区→半湿润偏旱区→半湿润区土壤水分含量呈逐渐增加的变化趋势，而且高值区一般出现在雨季恢复阶段或春季土壤融冻返浆时期；而低值区均出现在春季大量蒸发阶段或秋季缓慢蒸发阶段；就垂直变化而言，黄河流域不同旱作类型区土壤水分垂直变化的趋势均表现为上层变化幅度较下层大。

Simultaneously, the total extractible myoglobin decreased and the proportion of metmyoglobin increased significantly when the pressure above 400MPa. Beef discoloration after pressure processing may result from oxidation of ferrous myoglobin to ferric metmyoglobin, globin denaturation and structural changes. At 40℃, the changes of beef color was similar to that of room temperature's. When the temperature rise to 60℃, most of muscle proteins denatured, a small quantity of native myoglobin could not affect the color of beef significantly. Therefore, protein denaturation was attributed to the main cause of discoloration in beef muscle after pressurization at 60℃.

压力处理导致色泽变化的直接原因可能是由于二价铁的肌红蛋白氧化成三价铁的高铁肌红蛋白、球蛋白的变性及结构的变化所致。40℃时的压力处理，色泽的变化规律与室温下相似，只是色泽变化的程度更为剧烈，蛋白质变性在色泽变化中起到的作用逐渐加强。60℃下的压力处理，绝大部分蛋白质发生变性，少量未变性的肌红蛋白对色泽不会产生明显的影响，此温度的压力处理，蛋白质变性是造成肌肉失去红色的主要原因。

With distance from the lake,the Aerxiaote lake vegetation happened converse succession.From outside to inside,the structure of plant community was gradually simple,biological diversity was shrinking and halophytic vegetation had decreasing tendencies.From outside to inside,there were Aneurolepidium dasystachys,Phragmites australis,Suaeda salsa L.community.Succession tendency was from wetland and typical grassland vegetation to salinization and desertization vegetation.

阿尔肖特湖边的植被随着距湖面距离及地形的不同，植被发生逆向次生演替，自外向内具有植物群落结构逐渐简单，生物多样性逐渐降低、盐生植物逐渐增加有规律性变化趋势；植被由外至内依次形成了赖草、芦苇、白刺和盐地碱蓬群落梯度，其演替趋势是由湿地和典型草原植被向盐碱化和荒漠化植被过渡。

From Imperata cylindrical community to bare land,species of plants changed greatly, the importance value of annual herbaceous plants increased gradually and the importance value of perennial herbaceous plants went down gradually. The number of companion species went down gradually, the species richness and plant diversity index reduced. Community structure was from complex to simple.

从白茅群落到光板地，植物的种类发生了较大变化，一年生草本植物的重要值逐渐升高，多年生草本植物的重要值逐渐降低，群落中伴生种的数量逐渐降低，物种丰富度及多样性指数减少，群落结构由复杂到简单。

Nigrum and S. melongena seedlings presented a different rule. The leaf SOD activities of S. nigrum increased under low Cd (≤50 μM) and then decreased, POD and CAT increased continuously. However, SOD activities of S. melongena gradually decreased, POD activities increased and the CAT presented the rule of drop-rise-drop. SOD, POD, and CAT in the leaves of S. nigrum plaved an important role against Cd stress.

龙葵叶片SOD活性随镉胁迫程度的增加先增高后降低，POD和CAT活性基本上表现为逐渐上升趋势，而茄子叶片中SOD活性逐渐下降，POD逐渐上升，CAT呈先降后升又降的变化规律，龙葵体内的3种抗氧化酶对镉胁迫起到较强的抗氧化保护作用。
