致密

According to various of the technical difficulties such as low drilling efficiency in hard rock and short service life of diamond drilling bit, analysis was made on the inherent links between blade-extruding of hot-pressing diamond and rock abrasiveness.

中文摘要：针对在坚硬致密岩石中钻进时效低和钻头使用寿命短的技术难题，分析了热压钻头的金刚石出刃与岩石研磨性等岩性之间的内在联系，认为钻头的胎体成分及其性能是关键，硬而带脆性的胎体性能有利于金刚石出刃，从而能提高钻进速度。

In order to solve the problem of low efficiency and short service life of hot pressed diamond bit when drilling in hard and compact formation, relations between diamond exposure of hot pressed bit and rock abrasiveness were analyzed in this paper. Research on matrix performances of hot-pressed diamond bit was firstly carried out.

针对在硬而致密岩石中钻进时效低的难题，本文分析了碳化钨基热压钻头的金刚石出刃与岩石研磨性等岩性之间的内在联系，认为钻头的胎体成分及其性能是关键，硬而带脆性的胎体性能有利于全刚石出刃，从而能提高钻进速度。

Stability properties and oscillation modes of accretion disks around compact objects are studied in this paper.

研究了环绕致密天体的吸积盘的稳定性质和振动模式。

It is suggested that pair production may play an important role in the X-ray emission region which is formed by the accretion of a compact object.

本文提出：在致密星的吸积所形成的 X 射线发射区中，电子对的产生起着重要的作用。

The fern Adiantum capillus-veneris has an unconventional photoreceptor, phytochrome 3 (phy3), which is a chimaera of the red/far-red light receptor phytochrome and phototropin.

光敏色素-3的生成，可能是在第三纪和侏罗纪之间致密森林出现时使得蕨类植物能够适应黑暗环境的一个关键演化步骤。

The fluence and frequency of laser was controlled precisely, which could melt and destroy the adiposis tissue without damage to the adjacent tissues. The histological study of treated adiposis tissues, post-operative reaction and clinical results were observed and studied. Results Local adipose tissues were melted and liquefied effectively by the laser. Compact fibrous tissues of cellulite were broken by the laser into loosen structure. The bleeding was lower than traditional method due to the coagulation of capillary vessels. The advantages of laser lipolysis included less edema, petechia and complications, which produced a rapid recovery and satisfactory results.

但该方法也存在疼痛、血管损伤、出血较多[1]等不足，此法主要是利用机械力插入负压吸引管，通过较强的负压将脂肪组织吸出体外，比较适用于大范围、厚层次和疏松的脂肪吸除，难以应用于小范围局限致密的脂肪组织，如面颈部和手臂部等，这些部位脂肪构成较特殊，包含有大量坚韧的呈网状交织的纤维结缔组织，质地较紧密，普通负压难以吸除，吸脂管插入和抽动阻力较大，如强行反复抽吸对组织创伤明显，因此，有必要寻找一种更加有效的治疗方法。

This paper reviews the forming reasons of extremely low permeability of tight sandstone gas reservoir,including congenital aggradation and acquired diagenesis.

论述了致密砂岩气藏特低渗形成的原因：即先天的沉积因素和后天的成岩作用等。

Its language is dense and the structure amorphous.

其语言是致密的结构非晶。

The person's skull, combine very fine and hard, physiologist and anatomist ran out the method of everything, it integrity cent come out, there is all no this kind of physical strength, afterwards someone invention a method, be some plant of seed's put be just want dissect of skull inside, make with the temperature and the degree of humidity to it it germination, a germination, these seed then with terrible of strength, can't separate the whole machine dint of skeleton, integrity separate.

人的头盖骨，结合得非常致密与坚固，生理学家和解剖学者用尽了一切的方法，要把它完整地分出来，都没有这种气力，后来有人发明了一个方法，就是把一些植物的种子放在要解剖的头盖骨里，给它以温度和湿度，使它发芽，一发芽，这些种子便以可怕的力量，将一切机械力所不能分开的骨骼，完整地分开了。

At present international admiral is in measure of 1 ～ 100nm inside exceed small grain and its compact aggregation, and the material that by accept Mi Weijing makes is appellative material of the rice that it is accept, its include a variety of pulverous material such as metal, metalloid, organic, inorganic and biology.

目前国际上将处于1～100nm尺度内的超微颗粒及其致密的聚集体，以及由纳米微晶所构成的材料通称为纳米材料，其包括金属、非金属、有机、无机和生物等多种粉末材料。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
