有裂缝的

Bryophyte spores have three types of aperture, the trilete is original one, the monolete is the evolutionary character and the katalept is mostly common one.

苔藓孢子的萌发孔有3种类型：三裂缝为原始类型，单裂缝是进化性状，近极薄壁区是最常见的。

Most situation, you can use concrete silicone to caulk seal the cracks. When you have large cracks (over 10mm), you may wish to hire the professional to fix it.

大部分的情况下，你都可以使用混凝土专用的硅材料来填充这些裂缝，如果你有大裂缝（超过10毫米）的话，你应该聘请专业人士来处理。

Real estate experts, the general quality of the new premises cracks some common and not harm to the main structure, the maintenance could be solved; There are not easy to handle the cracks, some of the concrete itself may be limited, quality problems, and even reinforced their intensity and laying spacing problems may affect the useful life of housing, serious security problems will occur.

房产专家介绍，新房裂缝有些是一般的质量通病，不伤及到主体结构，维修就可以解决；还有的裂缝就不好说了，有的可能是混凝土本身的配比、质量有问题，甚至钢筋本身的强度和铺设的间距有问题，有可能影响房屋的使用年限，严重的会发生安全问题。

In type Ⅲ, the perispore is thin and the surface ornamentation is formed by the exospore.

孢子钝三角形，三裂缝，沿裂缝两侧各有一脊状隆起或瘤状纹饰；周壁薄，由外壁形成表面纹饰的基本轮廓；具赤道环、近极脊和远极脊。

The rocks consist predominantly of mudstone, evaporite, gypseous mudstone and glauberite dolostone. The reservoir spaces mainly include pores, cavities and fractures, with fractures predominating.

摘 要：江汉盆地潜江凹陷盐韵律发育，部分韵律层段存在有工业价值的油藏，岩性主要为泥岩、泥膏岩、含膏泥岩、钙芒硝质白云岩等，储集空间有孔隙、孔洞和裂缝，以裂缝为主。

If using humidly hardener, the surface can be humid, but there should not be any panice. b the surface should be fastness, compact and smooth, without any sand streak, floppy shell, crack, comb,bug holes. Using light blasting spray to clean the unevenness and incompact raffle, and getting the appropriate roughness, filling the crack with HF61-30 mixed with fine sand. C the surface must be clean, and have no oil stain.

如采用湿固化涂装，则表面可潮湿但不能有浮水。b水泥表面应坚固、密实、平整，不能有起砂、起壳、裂缝和蜂窝麻面等现象，可采用轻喷砂法除去水泥面上的不平整和不结实的杂物，并使其具有一定的粗糙度，对裂缝可使用HF61-30添加适量细砂填补。c表面必须清洁，须除去表面油污。

Optimalerror estimates in L2-norm and H1-norm are obtained.Model:The mathematical model for two phase incompressible flow innaturally fractured reserviors is[34]:Supposeis a bounded domain with smoothy boundary,the rock ispresented byΩi,the volume of the fissures is small,Ωm=Ω.In the fissures Ω:s(x,0)=s0,x∈Ωin the rock Ωi:where J=0,T.

模型：裂缝孔隙介质中油水两相不可压缩驱动问题的数学模型为[34]：设〓为具有光滑边界的有界凸域，其中多孔岩块以Ωi表示，Ωm＝∑Ωi，因裂缝体积很小，可以认为Ωm＝Ω。x在裂缝系统Ω上：〓s(x，0)＝s0，x∈Ω在任一岩块Ωi上：〓其中J＝0，T。

Comparing with former prediction methods, there are two progresses in it. First, the concept of fracture richness index is advanced and thus extend of fractures richness can be numerable.

与以前的预测方法相比，本次论文在以下两个方面有了改进：第一，提出了裂缝发育指标的概念，从而能够对裂缝发育程度进行量化。

But quite amount of cracks are found during the construction and operation in the PC box girder bridges, especially cracks in the anchorage zone and the inclined cracks in the box girder webs of the bridges, and some longitudinal cracks appear indeed in the deadweight phases,Moreover the variant Pre-stressed strand arrangements produce great influence for the inner inforce of the b

但目前在用预应力混凝土箱形梁的施工和运营过程中出现相当数量裂缝病害，尤其是箱梁锚固区裂缝、腹板斜裂缝，顶板纵向裂缝，有的甚至在未承受活载的自重阶段就出现裂缝，而不同的预应力布束方式对箱梁内力有很大的影响。

Although the theory believed, the cast-in-place concrete floor crack is a phenomenon which avoids with difficulty, but through the design, the construction and a series of strict technical management measure, reducing and avoiding the crack is completely feasible.in fact it also has quite many projects not to have the naked-eye obviously crack.

虽然理论认为，现浇混凝土楼板裂缝是难以避免的现象，但通过设计、施工等一系列严格的技术管理措施，减少和避免裂缝是完全可行的，实际上也有相当多的工程未发生肉眼可见的裂缝。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
