According to the basic theory of the soil mechanics and the comparison of two different experimental methods with different test instruments-electric heat drying cabinet and microwave oven, the water content of 30 groups of cohesive soil and 30 groups of cohsionless soil are tested.

根据土工试验的基本原理，采用微波炉和电热干燥箱两种不同仪器，进行两种不同试验方法的比较，完成了30组粘性土试样和30组砂性土试样含水率的测试。

These were raised underinducing condition to test if any morphology and structure changes. Twenty two Arabidopsismutants had various changes in morphology and anatomical structures. Twenty mutants hadlow germination rate from 10% to 60%, of which 2 had survival rates at 0% and 50%. Fivemutants occurred structure changes in the hypocotyls or stem. One of these lines, namedarris-stem, showed some unique changes: slower growth rate in comparison with the wildtype from germination to florescence; serrated margin of leaf blades, spiral rosette; morebranch in the bottom part of the stem, shorter nodes, twisted stem and branch. There were oneor several arrises along the stem. Across sections of the arrises showed one or several compactcells lumps which were round, made up of several layers of cells, looked like vascular-bundle.

在诱导条件下，这些突变体表现出不同的形态和结构的变化，共有22个表型和结构发生变化。20个突变系发芽率或存活率较低，发芽率由10％—60％，其中2个突变系存活率分别为0％和50％。5个突变系在茎或下胚轴的结构上发生变化，其中一个突变系arris-stem发生如下表型变化：从真叶出现至开花结实的整个生长期，生长速度要明显比野生型拟南芥缓慢；叶缘有明显锯齿，莲座叶呈螺旋状排列；茎的基部有较多侧枝，侧枝间距明显缩短，茎有明显扭曲；突变体茎侧面有1至数条棱形突起，内部存在一至数个排列紧密的细胞团，由多层细胞呈环形排列，细胞壁明显加厚，内部存在管状分子，推测为维管组织。

Lastly, the comparison of those PVDF hollow fibers membrane before and after modification has been studied by separately applied them to practically oil water (with confected concentration of 60mg/L) separation test, the decrease of water flux was measured, according to the results, grafted hollow fiber membrane showed better antipollution capability, it indicated that this method is practicable and effective.

最后，将改性前后的中空纤维膜分别应用于油水(自配浓度为60mg/L)分离试验，测定膜通量的衰减，数据表明改性后的PVDF中空纤维膜表面的抗污染能力有很大程度的提高，这说明用表面化学接枝改性的方法可以改善疏水的PVDF膜表面，该方法是切实可行的。

Correlations between defections measured by three different test devices have been established through deflections comparison and analysis...

通过数据分析与计算，得出了三种弯沉检测设备之间的相关系数和转换公式。

The finite element model included two types of main element: beam element for concrete and truss element for internal unbonded or external tendon. The end nodes of main elements were connected with internal constraints named MPC in ABAQUS. Spring elements with very large stiffness were set up at the place of the deviators of externally prestressed beams, or along the span with relatively little space of unbonded internally prestressed beams. The modified Riks method is utilized to trace the entire structural response of beams prestressed with unbonded tendon from zero to ultimate loads. The reliability of the analysis model is verified by analytical results of typical test beams in comparison with experimental ones.

该有限元模型由两类主单元组成，即混凝土梁单元和体内无粘结或体外预应力筋桁架单元；主单元的端部节点用ABAQUS的内在约束MPC连接；在体外预应力梁的转向块处，或沿体内无粘结预应力梁全跨并以比较小的间隔设置刚度足够大的弹簧单元。

The parameters of forging process and overheating temperature of 2214 forgings are determined through the comparison and test.

According to the comparison of test results of the new unit and the old one, it can meet the precision requirements. Moreover the temperature can be above 700℃, which can offer the high temperature circumstance demanded by catalytic pyrolysis, and overcome the shortcoming of temperature below 600℃offered by the old unit. The gas is collected by water displacement, and the resistant can be largely minished by extending the pipe diameter.
