The complicated oil field of karst cave and crack are controlled by limestone reservoir and the crevices-cave system, which have many characteristics such as vivid and great in style, irregular distribution, the limestone cave in crack and unhomogeneity of rock etc.

笔者力求充分利用各种开发生产的动态信息，探索研究和评价储层特征的方法及思路，主要研究成果如下：(1)结合塔河油田动静态分析和实践，将缝洞型碳酸盐岩油藏划分为三类组合模型：缝-洞系统、双裂缝系统和缝孔系统。

These are the square envelopes with slots of 10mm, 5mm and 0mm. The critical heating power of the two slotted square envelopes are both 21 Watts, but for the case of the unslotted envelope it is much smaller.

对圆内四边形开缝为10mm，5mm，0mm三种情形，实验结果表明在实验Ra范围内，存在振荡解，其中两种开缝情形下稳态解转变为振荡解的临界加热功率都是21W，而开缝为零的情形下临界加热功率则要小得多。

These buildings usually have no or less expansion joint, which leads to the length of whole structure oversteps the value our country Coad prescribed.

由于考虑到建筑上的美观性和结构上的整体性，这些建筑往往不设或少设温度伸缩缝，致使通长不设缝的结构长度远远超出了我国规范规定的伸缩缝限值。

Brick joints of arch and vault shall be staggered and control line shall be introduced from longitudinal joints to keep straightness of brick surface.

拱或拱顶应错缝砌筑，错缝砌筑的拱和拱顶，应沿纵向缝拉线砌筑，保持砖面平直。

In order to improve the low temperature performance of modified asphalt and mixture of bridge expansion joint s,and put it into use successfully in small and middle span bridges expansion joints in low temperature areas,authors modify the MEIJIA materials by adding thermoplastic elastomer and rubber.

为改善改性沥青桥梁伸缩缝材料的低温性能，使其在寒冷地区中小跨径桥梁上获得成功应用，通过添加热塑性橡胶类改性剂和橡胶类改性剂，对美佳改性沥青结合料进行二次改性，并通过对改性前后结合料和混合料低温性能的试验对比分析，重点研究了伸缩缝用改性沥青结合料和混合料的低温性能，通过实桥伸缩缝验证了研究成果的可行性。

In nearly two hundred years of history, the sewing machine from simple to mechanical braking, electric manual to advanced digital, computerized sewing machine, although the sewing machine technology development through innovation, but its basic principle, always is lines and lock chain type line mark for the most basic of sewing thread sewing, key elements of the fabrics is suture.

而在近两百年的缝机发展史中，从简单的手动到机械制动、电动，再发展到先进的数字化、电脑化缝机，虽然缝机技术经过了不断发展创新，但其基本工作原理变化不大，始终是以链式线迹和锁式线迹缝制为最基本的缝制方式，即线是缝合面料的关键要素。

Whether decorative seams or inserting zippers or velcro tape up to topstitching of closing seams - the lockstitsch machine 767-FAS-473-RAP-HP offers best conditions for all twin-needle operations on plain cut pieces.

无论是装饰线缝或是嵌入拉链或尼龙搭扣衬条，还是在拼缝上压明线- 767-FAS-473-RAP-HP锁式线迹缝纫机均为在大面积缝片上进行双针操作提供了最好的条件。

The general situation of hydraulic AGC techniques for copper cold rolling mill s is introduced, the direct measurement and closed loop control for mill gap are simply described, the natural rigidity of mill and the equivalent rigidity in gap control are analysed and compared, and at last the realization of a gap direct measurement AGC system is simply described as an example.

介绍了铜带冷轧机液压AGC技术的概况；简述了轧机辊缝直接测量和闭环控制，并对轧机自然刚度和辊缝控制的等效刚度作了分析比较；最后，作为实例，简要说明了一个辊缝直接测量AGC系统的实现。

Again, I maintain that we should use the flexural-tensile strain and the vertical shearing stress of the bottom of cover of the joint as the target for the design of the cover structure of asphalt on the old cement concrete. In addition, on the basis of much theoretical analysis, I preliminarily put forward to a designing methods to anchor the old cement concrete road by using dog irons made of iron bars and then covering it using asphalt concrete structure. Finally, through selecting the plan of the cover of the road to be experimented, and making a detailed introduction to the techniques of construction according to the result of theoretical analysis, I know that after anchoring the slabs close to each other with dog irons made of iron, and then cover them using asphalt cement concrete has an obvious effect on preventing and slowing down the reflection cracks in the bituminous concrete skin coat over the old road.

在大量分析的基础上提出了马钉锚固罩面结构中相邻两块水泥混凝土板接缝处的相对水平位移、相对垂直位移、接缝处沥青层底部的弯拉应变和剪应变的计算公式；再次，提出了采用接缝处罩面层底部的弯拉应变、垂直剪应变作为旧水泥混凝土路面上沥青混凝土罩面结构的设计指标，并在大量理论分析的基础上，初步提出了马钉锚固旧水泥混凝土板后沥青混凝土罩面结构的设计方法；最后，根据理论分析的结果，选定试验路的罩面方案，并对其施工工艺进行了详细的介绍，表明采用钢筋马钉锚固相邻混凝土板后，再进行沥青混凝土罩面的方法在防止或减缓罩面层反射裂缝方面具有明显的效果。
