For low permeability oilfields, radial flow straight-line portion should not appear in producer measuring data during shut-in build up tests. A practical method to interpret formation parameters based on well testing data at early fillup period has been established With the application of this kind of method, ideal interpretation results can be obtained when the measure pressure data lie above and under semilog straight-line portion, and the formation parameters can be interpreted more reliably.

对于低渗透油田，在通常的关井压力恢复测试中，油井测压资料不能出现径向流直线段，针对这种情况建立了一种用早期续流段试井资料解释地层参数的实用方法，通过计算续流量利用褶积分析方法解释早期试井资料，可对实测压力数据点落在半对数直线段上方和下方的两种情况都收到较理想的解释效果，能解释出比较可靠的地层参数。

Fan appears top be on more of the time than with the M912X we tested. Slightly annoying but seems have a noticeable effect on reducing heat build up.

ABSTRACT In order to study the thermally activated characteristics of plastic deformation and the effect of alloying element on the thermal activation of structural steels, the properties of plastic deformation for 20g and 13Ni3CrMoV steels have been examined in the temperature of 77—473K and strain rate of 〓. The experimental phenomena show that the effective stress of plastic deformation decreases with the increase of alloying elements content (namely solute solution softening) and the frequency factor deceases with the increase of effective stress.

本文以13Ni3CrMoV钢焊接结构的动态断裂破坏为背景，通过系统测试20g和13Ni3CrMoV钢的动态屈服特性，分析比较了结构钢的形变热激活特点，从频率因子〓随有效应力σ〓增大而下降和合金固溶软化的实验现象出发，在位错以弯折方式克服晶格Peierls位垒的基础上，提出了溶质原子与螺型位错热激活弯折相互作用的物理模型和σ〓-T分段线性关系的形变热激活理论假设，并借助计算机数值模拟，分析探讨了合金固溶软化的微观机制。

A number of calculation examples, including past experiments, our experiments, thick slabs experiments, thin slab experiments, single slab experiments and doweled slabs experiments, are given. By comparing test values with calculating values, some significative conclusions are drawn. The superiority of generalized conforming element for thick-thin slab on foundation is pointed out. The average ranges of foundation parameters are given according to these experiments.

6利用有限元程序进行正分析，用遗传算法进行反分析，识别地基的基本参数，实现地基参数的原位测试；给出大量算例，包括前人的试验和本文的试验、薄板与厚板、单板与接缝板，通过计算值与实测值的比较，得出一些较有意义的结论；阐明了双参数地基上广义协调厚薄板通用元的优越性并给出了试验场地地基参数的平均取值范围。

CNTs/PTFE and CNTs/epoxy composite materials were used as field-emission cathode and the two electrode configurations were encapsuled into a static vacuum system respectively.

通过对比测试，研究了两种复合材料阴极在静态真空系统中的场发射特性，比较了两者在不同场发射电流密度时的电流稳定性，以及随着封装后时间的增长对静态真空系统场发射性能的影响。

If a specially appionted solvent is used in esterifying reaction, APG to solvent will be 1 to 0.6-0.7. And then, the final yield is more than 70％,and its properties indicate that it is a better anion surfactant. Such can pave the new way for the application of APG.

若酯化反应选一合适的溶剂，则APG：溶剂为1∶0.6-0.7时，阴离子活性物含量可达70％以上，测试其性能，表明为比较优良的阴离子表面活性剂，这样就为APG的应用开辟了新途径。

In this way, comparison with experiments on fluxed pellets from those tests can be performed.
