使降低

The gaseous impurities in the alloys were well controlled with the sum of C, N and O less than 500wppm. For the first time it was found the strong interaction between Cr-Ti-CON, which reduces the mobility of Ti and CON, enhancing high-temperature strength and the aging-hardening property, and keeping the cold-work induced hardening at higher temperature. Aging-hardening could increase the tensile strength of V-4Cr-4Ti by 30% and could be utilized at 00 C for better economical performane of a vanadium structure. Hydrogen release will occur for the alloys tensile loaded at room temperature, which will affect the safety of a vanadium structure due to the resulting dimensional instability. For hydrogen embrittlement, impact toughness and fracture toughness of the alloy showed higher sensitivity than the tensile test elongation,so the toughness should be used as a new standard for the assessment of the embrittlement. Vanadium alloys were easily oxidized in air.

合金的气体杂质含量得到有效控制，C、N、O总量低于500wppm；首次发现Cr-Ti-CON之间的强相互作用，它使Ti、CON的高温可移动性降低，提高合金的高温强度、增强时效强化特性、使冷加工强化保持到更高温度；时效强化可使V-4Cr-4Ti的强度提高30%，可在低温（00C）下应用，提高构件的经济性；室温下，钒合金在拉应力的作用下，存在着氢释放，带来部件使用中的尺寸不稳定性，影响构件安全；氢脆是钒合金聚变应用的一个关键问题，合金的冲击韧性和断裂韧性表现出比拉伸延伸率更强的氢脆敏感性，应作为评价合金氢脆行为的新标准。

The article mainly analyzes how innovation affects the social welfare and makes some conclusions as follows: firstly, influences on the price and output of products of innovation by oneself are uncertain, but innovation can enhance social welfare when it reduces the product price or raises the price but diminishes the elasticity of inverse demand curve.

本文重点分析了企业创新对社会福利的影响，得出的主要结论如下：（1）独立创新对产品价格和产量的影响是不确定的，但当创新使产品价格下降或者创新使产品价格上升且使反需求曲线的弹性变小时，独立创新能够增加社会福利；（2）联合创新能够降低每个企业的成本，增加企业的研发开支、产量和利润，因而联合创新有利于社会福利；（3）在考虑了创新的溢出效应后，存在一个外溢比率的帕累托最优区间，但我们必须在创新激励与社会福利之间做出权衡。

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。
