The results show that the density of gritstone is decreased gradually as the temperature increasing; so that it can be ignored; the longitudinal wave velocity is linearly decreased when the temperature increasing, and decrease rate of it follows the law of conic; R is one temperature point, which makes the law of tensile strength of gritstone after high temperature follows the law of parabola; and the maximal tensile strength appears when the operative temperature is R. After the temperature is higher than 700 ℃, tensile strength is small and change range is small when the temperature is increased.

结果表明，高温后粗砂岩的密度随试验温度的升高减小幅度很小，几乎可忽略不记；高温后试件中纵波波速的传播随温度升高基本呈线性降低，而减小率呈二次曲线规律变化；存在一个温度点R，使高温后试件的抗拉强度呈开口向下抛物线关系变化，且在R温度作用后试件抗拉强度达到最大；当试验温度大于700 ℃后，试件的抗拉强度变得很小，且当温度升高时变化幅度也很小。

In presence of non- cancer suspicious patients, serum MMP-2 activity in chronic hepatitis is contrary to decrease at lowest among them. The level of MMP-9 similarly low compare with normal control. Therefore found out that the process from chronic hepatitis to hepatoma, a variation of MMP-2 is earlier to decrease and then to rise. Although there is no great variation but lower in MMP-9 compare to normal control.

肝癌病人的血清中MMP-9及MMP-2两者的变化与正常人相比差距最易观察，当比较所有非癌症病人血清时，慢性肝炎病人血清MMP-2活性表现相反的下降，而且是其中最低的，因此可以看出由慢性肝炎到肝癌的过程MMP-2的变化是先下降再升高，MMP-9虽然没有大变化，相较於正常人却都偏低。

Using the changing rate of maximum feed-rate as a threshold,the surface of the part is divided into different areas according to the values of normal curvature radius.Then the feed-rate is adjusted by constant velocities of cutter contact,thus the adaptive variation of feed-rate can be reached.An example is given to prove the ra...

以最大工作进给速度的变化比率为阈值，把零件表面的法曲率半径划分为不同的区域；在不同的曲率区域内，分别以恒定的刀触点速度对进给速度进行修正，修正后的进给速度随着零件表面曲率的变化而自适应变化；实例表明该方法具有合理性和有效性。

Under the condition that the maximum index change at the core-cladding interface and absorption coefficient were constant, the numerical results indicated that the reflectivity of cross-mode coupling peak between LP_ 01 and LP_ 11 modes varies parabolically with the saturation length of index change.

仿真结果表明，在纤芯和包层边界的最大光致折射率变化量和纤芯吸收因子不变的情况下，随着纤芯折射率变化的饱和长度的增大，LP01和LP11模间的互耦合反射峰呈抛物线形变化，当饱和长度增大到一定值后，互耦合反射峰随饱和长度的增大而逐渐减小并最终消失；同阶LP模的自耦合反射峰随饱和长度的增大而增大。

The main conclusions indicated that NDVI values seemed to be turning up in the area during recent 22 years (1982—2003). That suggested the vegetation cover was improved in Guizhou. The NDVI increased in the spring and autumn and decreased in the summer and winter. The spring made the largest vegetation contribution in all seasons. Vegetation cover was different from the area and the variation was positive in the central area but negative around the edges of Guizhou.

结果表明：22年来，研究区植被覆盖呈增加趋势，表明贵州省植被生态环境向好的方向发展；贵州省平均植被覆盖在春季和秋季呈上升趋势，夏季和冬季呈下降趋势，其中春季对植被覆盖总变化量的贡献最大；植被覆盖程度增减因区域不同而异，变化程度呈增加的区域主要位于贵州省的中部地区；变化程度呈减小的区域分布在贵州省的四周边缘。

The seasonal variation of the upper layer heat content is controlled jointly by both the dynamic process and the net heat flux from the sea surface, and it can be mainly attributed to the air-sea interaction.

由动力过程和海表净热通量共同控制，2种作用都有明显的季节变化特征，并且随区域的变化两者贡献有所变化；西南季风爆发前，上层海洋热含量最大值的出现，是之前几个月动力作用和海表净热通量共同加热的结果。

The result of variance of analysis showed that the germination capacity of treatment in 15,18,19,23,24,were all higher than 85 percent.15 treatment was best from single direction of germination capacity and 18 and 23 were best both from germination capacity and sparing irrigation ,namely when holard was 20%-25%,irrigation was 60m~3/hm~2.(2) Pn showed single peak curve at different holard and irrigation.

不同土壤含水量及不同坐水量处理时，光合速率在整个生育时期呈单峰曲线变化，不同土壤含水量处理均在抽雄期达到最大值，土壤含水量较高时，光合速率较高，变化迅速，土壤含水量较低时，光合速率也较低，变化缓慢。

The protease activity in foregut was higher than that of midgut in an acidic condition at pH 5.0-5.8, while in an alkalescence condition at pH 7.0-8.6, the protease activity was higher in midgut than that in foregut. The lipase activity of foregut was high and stable in two pH ranges: 4.2-5.0 and 6.2-7.0, and that of midgut was high at pH 3.8, while the lipase lost enzyme activity at pH over 9.0. The amylase activity was high and stable at pH 6.6-7.4 in both foregut and midgut. The cellulase activity of foregut and midgut was high and stable at pH 6.2-7.4 and 5.4-7.0 respectively.
