Results Pit and fissure filling has effectively prevented the further development of caries. In test group no case developed intermediate caries from superficial caries. On the other hand the proportion of the intermediate caries in control group was 32.94%.

The influence of fissure filling was considered in the interface model to simulate the opening increase of cracks.

在接触面模型中考虑裂缝填充物的影响，模拟填充物引起的裂缝开度逐年递增；

Finally, some problems needed for further study are put forward, including the regularity of fissure deformation and fracture under shear loads, the influences of shear loads on fissure permeability under different normal loads, constitutive relationship of fissured rock mass, etc.

指出了需要进一步研究的问题：剪切荷载作用下裂隙变形和破坏规律；不同法向荷载作用下剪切荷载对裂隙渗透性的影响；

Rock mass is discontinuous because of the movement and development of the crust. The joint, fissure, fault fracture are the typical modes of this discontinuation.

岩体介质由于地壳的不断运动、发展，呈现出显著的不连续性，存在大量的节理、裂隙等不连续界面。

Through grouting experiments in a single fissure and fracture networks, the basic law controlling the grouting seepage through rock mass is analyzed, and the factors which may affect the process are also discussed.

通过单一裂隙岩体和裂隙网络岩体注浆渗流模拟实验，分析和总结了裂隙岩体注浆渗流中的一般规律，并讨论了影响注浆渗流工程的各种因素。

The mechanical property of N80 steel has increased obviously after adding corrosion inhibitor, where the ductility of N80 steel increased, and crack fissure of fracture surface decrease.

添加缓蚀剂后使N80试样的韧性有明显的增加，断口裂纹缝隙明显减小，力学性能有了明显的提高。

Opening point, opening angle and maximal tangential stress on ellipse edge are presented under uniaxial compression, biaxial compression and uniaxial compression with fissure water pressure respectively.

分别给出了单向压力、双向压力、单向压力与裂隙水压力共同作用3种情况下椭圆边缘开裂点的位置、开裂方向和最大切向拉应力值。

In addition, we also found one case of rare variants of the lateral fissure vein, 1 ( 1%). 2.

除此之外，我们还发现1种罕见变异类型的外侧裂静脉，占1%。
