无裂缝的

Probably the most problematic situations are the naturally fractured formations where the operator may face total loss with no mud return in the annular.

大概是最有问题的情况下，是自然形成的裂缝所在的营办商可面对全损无泥回报，在环形。

As they drew nearer, however, his face shone through the gloom, hairless, snakelike, with slits for nostrils and gleaming red eyes whose pupils were vertical.

当他们接近后，他的脸愈发阴沉，无毛、蛇状，有着裂缝般的鼻孔和闪着红色的眼睛，瞳孔竖直。

Branchlets not virgate, gray-brown or dark brown, scabrous, with longitudinally arranged slits, not shiny; leaf blade leathery, spatulate or rhombic-elliptic, apex truncate or acute, adaxially glabrous or midvein sparsely puberulent, abaxially with ± dist

小枝不棒状，灰棕色或者暗褐色，粗糙，带有纵向安排的裂缝，不发亮；叶片革质，匙形或菱形椭圆形，先端截形或锐尖，中脉疏生微柔毛的正面无毛或，背面具多少dist 42 R。 rosthornii 小冻绿树

Sessile spikelet 3–4 mm; lower glume obliquely ovate, with 6–8, prominent, riblike veins separated by deep slits, slits interrupted by tubercle-based hairs along their length, margins narrowly winged toward apex; upper glume keeled toward apex, keel winged; lower floret reduced; upper lemma and palea subequal.

Exerting surrounding pressure can prevent crack growing in a uniaxially compressed concrete specimen. The behavior of concrete in which there is no crack propagation (called ideal state without damage growth) is researched in this paper.

通过对混凝土施加围压，使单轴受压混凝土的裂缝发展受到限制，从而研究混凝土在接近无裂纹发展状态下的受压性能。

It uses the latest manufacturing technology, the unique structural design, processing and end product was the cube, no tension and cracks, grain shape pretty well, can crusher feed size less than 500mm, not more than 350MPa compressive strength of the various coarse, medium and Fine materials granite, limestone, concrete, etc.

它采用最新的制造技术，独特的结构设计，加工成品呈立方体，无张力和裂缝，粒形相当好，能破碎进料粒度不超过500mm、抗压强度不超过350MPa的各种粗、中、细物料（花岗岩、石灰石、混凝土等），广泛应用于各种矿石破碎、铁路、高速公路、能源、水泥、化工、建筑等行业。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
