采用压汞分析技术对秦岭多金属成矿带西成矿田洛坝铅锌矿床含矿层各岩系的物性特征进行了研究，结果表明含矿层各岩系物性特征具有孔隙度小、渗透率低、孔喉连通性差的特点，这一特征对洛坝大型矿床的形成是极为不利的。

The other technique was so called "Constraint Induced Movement Technique" to apply a shoe lift or wedge under the stronger limb, providing a compelled shift of the body weight onto the paretic limb to increased ability of weight bearing. This technique helps patients achieving symmetry of stance and weight bearing and overcoming the learned disuse mechanism. Therefore, the purpose of this study was to investigate the effect of 5° lateral wedge on non-paretic limb improving symmetry of stance and weight bearing for stroke patients.

另外有一种技巧和方法为强迫诱发运动，在健侧使用鞋垫，强迫病患把身体的重心移到患侧去，藉此增加患侧脚承载的能力，研究有使用加高型或外侧楔型的鞋垫，目的都是要使中风的病患能有较对称的站姿及两脚有较对称的重量承载比例，如此一来可以强迫患侧使用更多，进而克服学习废用机制，上述研究多为急性期病患的探讨且多是观察当下的影响及效果，因此我们想利用外侧楔型鞋垫的帮助，藉由在健侧脚较长时间的穿著，看看对於慢性中风病患的站姿控制所造成的影响。

Based on the load transmission mechanism of space truss, and referenced theanalysis of test materials, a formula for calculating the bearing capacity of reinforcedconcrete compression strut is introduced. By using the theory of plastic hinge-line, anupper limit solution of bent bearing capacity for four-pile cap, which coincidesprecisely with the practical measurements, is obtained. By utilizing the reaction ofthe soil under cap and by basing on the method of plastic ultimate analysis, an upperlimit solution of punching shear bearing capacity for pile cap is acquired, which. coincides precisely with the practical measurements, and the formula is similar to thecode.A brief discuss on cooperative work of strip beam of foundation and single rankof piles is made. Separately considering the pile-cap and the pile-group, thencoupling their matrix of rigidity, the inner force of pile-cap is solved by the numericalmethod under some reasonable supposition. In comparison with other method, thecalculating results are exact, reliable and convenient in using. The method provides apowerful tQol fOr further analysis and research on this kind of structure.
