It is embodied concretely:(1) With the adoption of grouting bolts, the cranny in wall rocks can be blocked up, the air can be isolated, the wall rocks can be prevented to be weatherized and make water, the strength of wall rocks can also be avoided to be lowered;(2) The lax broken wall rocks are commentated to a whole by liquid after they were grouted and the rock"s strength is increased, so the wall rocks become a part of the support structure by using itself and become a whole with the original rock, and the roadway is made to keep stable but not easy to be broken;(3) The spray layer wall are filled with liquid after grouting, the stress is avoided to be concentrated because the load could be evenly acted on the spray layer and the support;(4) The pressure acted on the plank can be delivered to the two sidepieces and then to the bottom by reinforcing the sidepiece; At the same time, the concentration degree of loads acted on the motherboard can be weaken because of the enlargement of the combination arch"s thickness, as result, the rock"s stress is lowered and the heaving is alleviated;(5) The common bolt is made to be fixed the whole length after grouting, the layers are connected to a integral whole and bear the weight of loads, so the support structure"s unity is increased.

具体体现在：(1)采用注浆锚杆注浆，可以利用浆液封堵围岩裂隙，隔绝空气，防止围岩风化，且能防止淋水和渗水，避免围岩被水浸湿而降低围岩的本身强度及造成的巷道变形。(2)注浆后浆液将松散破碎的围岩胶结成整体，提高了岩体强度，实现利用围岩本身作为支护结构的一部分，且与原岩形成一个整体，使巷道保持稳定而不易产生破坏；(3)注浆后使得喷层壁后充填密实，保证荷载能均匀地作用在喷层和支护上，避免出现应力集中点而首先破坏；(4)注浆后使作用在顶板上的压力能有效地传递到两帮，通过对帮的加固，又能把荷载传递到底板；同时由于组合拱厚度的加大，这样又能减小作用在底板上的荷载集中度，从而减小底板岩石中的应力，减轻底臌；(5)注浆加固后能使普通端锚锚杆实现全长锚固，它们共同将多层组合拱连成一体，共同承载，提高了支护结构的整体性。

High pressure jet grouting is one of these methods.

高压旋喷注浆是其中的技术方法之一。

If the injection period is extended long enough, the effects of isolated eddy cavities are neutralized.

如果喷注时期延续得足够长，隔开的涡流区的影响被抵消。

After the typical working characteristics of STIG cycle being illustrated, the performances of the air cooled STIG and ISTIG cycles are investigated, including the influence on the steam injection rate exerted by the recovery boiler's working limitation of pinch point temperature difference, the minium superheat temperature and the minium exit temperature.

分析STIG循环的典型工作特点，讨论采用空气冷却方式的STIG及ISTIG（采用中冷技术的STIG）循环的工作性能，尤其是余热锅炉节点温差、最低过热度、最低出口温度等限制因素对蒸汽喷注量的制约影响。

High transverse momentum partons which come from hard scattering will propagate in the strong interaction medium and interact with matter. These partons are expected to lose their energy in the medium by gluon bremsstrahlung, which is called Jet Quenching.In BNL/RHIC Runl (S_~(1/2)= 130GeV and Run2 (S_(NN~(1/2)= 200GeV, comparing the yield of leading particle in nucleus-nucleus collisions with nucleon-nucleon collision finds that charged and neutral pions are suppressed.

在相对论重离子碰撞中，末态高横动量强子产额的压低被认为是夸克胶子等粒子体已经生成的一个重要信号，在高能核-核碰撞过程中，硬散射发生在碰撞过程的初期，由硬散射过程形成的大横动量部分子将穿越强相互作用物质，这些硬部分子与热密物质发生强相互作用，经过韧致辐射而损失能量，我们把这种现象称为喷注淬火。
