The method which is used to measure and compute moment, yield and turning angle by steel bar gauge is introduced in detail. According to the measuring results, the horizontal critical load of the testing pile is 120 kN. The steel bar gauge measuring results show that the largest moment is located in the depth from 2 m to 3 m under the horizontal load, it transfers to the deeper location with the increase of the horizontal load, and the bend distortion only occurs in the upper of 1/3 pile length.

结合实际工程详细地介绍了利用钢筋计测试水平荷载作用下桩身弯矩、挠度和转角分布的方法，根据桩顶位移和钢筋内力测试结果判定试验桩的水平临界荷载为120 kN；根据钢筋计测试结果可知，在水平荷载作用下，桩身最大弯矩截面位于在地面以下2～3 m处，且随着荷载的增大最大弯矩截面逐渐向深部转移；发生弯曲变形的部分主要是桩长1/3以上的桩体，而其下的桩体几乎不发生变形。

In the existing buckling analysis of drill stem in horizontal condition,the drill stem is thought of as an even rod with equal diameter and sticked on the below wall of well on the action of deadweight,so it was simplified as simply supported beam compressed axially and supported evenly along its length by well wall.

在现有的水平状态下钻柱屈曲研究中，一般把钻柱看作均匀的等直径杆，认为钻柱在其自重的作用下，紧贴下井壁，因而通常把水平状态下的钻柱简化为在整个长度上受到井壁均匀支承的轴向受压的简支梁。

The anastomosing occurred between the pleural superficial and the subpleural vascular networks on the capillary level or the precapillary level. The honeycomb vascular networks were also various in size and form at a low magnification. The venule connected with the pulmonary capillary networks directly at a high magnification. The single capillary networks were found in the alveolar septa. The longitudinal crests and dense round imprints of endothelial nuclei and the clear circular constrictions were found on the surface of the larger vessel in the lung parenchyma. The round imprints of endothelial nuclei also occurred on the subpleural venule and capillary.

The recoery rate was calculated as follows;(JOA score at follow up_preoperatie JOA score)/(17 _ preoperatie JOA score) _ 100,15 and the surgical outcomes were classified into four grades based on the calculated recoery rate; excellent: recoery rate 75% or higher, good: 50–75%, fair: 25–50%, and poor: lower than 25%. Ealuation was made on radiographic findings, including the range of motion and the jaw diameter (a measured line from the posteroinferior corner of the ertebral body to the anterior aspect of the subjacent lamina) at the adjacent leels in group A and the affected leels in group B and the spinal canal diameter at the C4 leel in both groups. The C4 leel was chosen for this measurement, because the spinal canal is usually narrowest at this leel.

第四章对尉犁绿洲系统近10年来的承压超载状况进行了分析，结果发现，自1991年以来，在小康、富裕与现代化等不同生活水平约束下，尉犁绿洲系统都处于超载状态，生态环境脆弱、经济发展水平低下、基础设施落后、人口素质低下与生活水平处于较低水平是尉犁绿洲系统处于超载状态的根本原因；但从整体看，尉犁绿洲系统的承载状况趋向好转，主要原因在于尉犁绿洲人口规模小、人均资源利用指标处于较高水平、水利设施条件进一步改善和绿洲居民预期寿命始终处于较高水平。

A 2D two phase horizontal fracture model was established when studying hydraulic fractures for the requirement of shallow reservoir stimulation in this block; and a 3D two phase model has been built for numerical simulation of a reservoir with five-spot pattern without considering vertical fracture flow. The impacts of horizontal fracture half length and flow conductivity on recovery factor and ultimate recovery factor are studied for some certain injection and production conditions. The parameters of hydraulic fracturing are optimized.

Applied with test of potted plant and measurement absorbency for study response of the contents of photosynthetic pigments of slash pine's half-sib under water stress. There are 7 families comparison with general slash pine. The contents of photosynthetic pigments are mensurated under feebleness water stress while soil water content is 55% to 60% and moderate water stress while soil water content is 35% to 40% and heavy water stress while soil water content is 20% to 25%. The test result indicate that either water grads or families of chlorophyll and chlorophyll a and chlorophyll b and Chla/Chlb and carotenoid and Caro/Chl are mighty notable difference. The Chl and Chla and Chlb and Chla/Chlb little drop from normal soil water to initial water stress. Then drop obvious with increased water stress. The Caro and Caro/Chl little drop firstly from normal soil water to initial water stress,then up in metaphase water stress,after drop in evening water stress. The Chl and Chla and Chlb and Chla/Chlb and Caro of slash pine'half-sib are over general slash pine. The Chl and Chla and Chlb and Chla/Chlb and Caro of 464 and 1027 are over average value of slash pine's half-sib under water stress. The Caro/Chl of 609 and 46 are over average value of slash pine's half-sib under water stress.
