The results show that proper RRA heat treatment can improve SCC properties with retention of the high strength of T6 level. After preaging at 100℃for 24 h, retrogression at 200℃for 7 min, and reaging at 100℃for 24 h, the ultimate tensile strength, yield strength and elongation of the alloy are 795 MPa, 767 MPa and 9.1%, respectively. Meanwhile the failure time of the alloy applied to tensile strength of 210MPa in 3.0%NaCl+0.5%H2O2corrosion condition is longer than 720 h. The corresponding TEM observation shows that after retrogression for 7 min and re-aging treatment, the microstructure of grain boundary is similar to that treated in the T73 condition with coarsen and isolated distribution, and the microstructure inside grain is similar to that treated in the T6 condition with small and homogeneous distribution.

At present under the socialist market economy condition, completes the enterprise staff thought political work the key is the Central Party Committee 17 big spirits in every sense of the term implementations basic unit Since the specially reform and open policy, has had many head of undertaking, deceives both superiors and subordinates works for one's own interests under the guise of working for the public, thought the present does not have the movement, in the waist the animal pen axe, the fan which in the hand takes, often on greatly sends the arms, teaches whips the staff, often on to the authority coerces the staff, simply not staff when the person looked, the wages casually decides, bully softly, is hard feared, pays out the wages not to have the pay list, wants to give how many to give how many, Sunday does not let the staff rest, does not pay adds the spot to spend If you offer an opinion to him, regards you is the thorn in one's side, the thorn in the side, does everything possible to carry on retaliates you, and direct descendant wilfully tolerates using the hand in authority to oneself, to give the green light to something, to holds the different political view greatly to open killing They use in the hand two "magic weapon" to benefit as the third party in a dispute, deceive both superiors and subordinates flatter the higher authority, exploits power, violates the country head of undertaking the cadre relative about to forbid in this enterprise to be engaged in production management the stipulation Also uses in the hand the authority private full center pouch, is greedy, does everything possible to concoct pretexts makes the forged account, high keeps off the office supplies with the government money purchase modern age to converge the oneself to have, makes the forged account to reimburse the beach person cost, digs national the corner of a wall Then receives using the duty gives the sales commission,包产 outside the package exits the enterprise outside, fishes for the wealth, even allies the annual bonus, violates the country and the enterprise stipulated, then 参股using the duty manages the enterprise But greatly gives the discount in the staff benefit treatment aspect, in 工资分 is joined to greatly makes the issue, drills the national policy spatial, borrows the wage reform is the excuse, seeks the benefit for own clique, borrows the work then to provide the special sedan car for the enterprise basic unit leadership, all expenses completely are responsible by the unit, to become not to pay the solid private sedan car The party and the country stressed repeatedly that, strictly prohibits the leading cadre to exploit power, but such stipulation into head of undertaking cadre's neglected advice, really it may be said in has the policy, gets down has the countermeasure If the country does not carry on effective supervising and managing to the enterprise, does not carry on the strengthened management, gets down for a long time, they can depend on right and not the improper income become the millionaires and surely the wealthy man, the state asset can massively drain, but government's policy can become a mere scrap of paper, loses it in common people's prestige Let these clothes eating insects embezzle national the property, thus causes the enterprise to move towards goes out of business, such example is too numerous to cite individually The working class is the national master, such formulation until now is does not have the question, but present working class's actual condition how?

目前在社会主义市场经济条件下，做好企业职工思想政治工作的关键是把党中央十七大精神不折不扣的贯彻到基层。特别是改革开放以来，有不少的企业领导，欺上瞒下假公济私，认为现在没有运动，腰里苄着斧子，手里拿的扇子，动不动就大发干戈，训策职工，动不动就以权力要挟职工，简直不把职工当人看，工资随便定，欺出软，硬出怕，发工资没有工资单，想给多少给多少，星期天不让职工休息，不付加斑费。如果你给他提意见，就视你为眼中钉，肉中刺，想方设法进行报复你，利用手中的权力对自己和嫡系任意纵容，大开绿灯，对持不同政见者大开杀界。他们用手中的两件"法宝"渔翁得利，欺上瞒下讨好上级，以权谋私，违反国家关于企业领导干部亲属禁止在本企业从事生产经营活动的规定。还利用手中的权力私饱中囊，多吃多占，想方设法巧立名目做假帐，用公款购买现代高挡办公用品归为己有，做假帐报销滩人成本，挖国家的墙角。利用职务之便收授回扣，把企业外包产品外包出去，从中捞取钱财，甚至加盟人股，违反国家和企业规定，利用职务之便参股办企业。而在职工福利待遇方面大打折扣，在工资分配上大做文章，钻国家政策的空，借工资改革为借口，为自己的小集团谋利益，借工作之便为企业基层的领导配备专门的小轿车，一切费用全部由单位负责，成为名不付实的私家小轿车。党和国家一再强调，严禁领导干部以权谋私，而这样的规定成为企业领导干部的耳旁风，真可谓上上有政策，下有对策。如果国家对企业不进行有效监管，不进行强化管理，长期下去，他们会靠正当和不正当的收入成为百万富翁和千万富翁，国有资产就会大量流失，而政府的政策就会成为一纸空文，失去其在老百姓中的信誉。让那些蛀虫侵吞国家的财产，从而使企业走向倒闭，这样的例子不胜枚举。工人阶级是国家的主人，这样的提法至今是没有问题的，可是现在的工人阶级的实际状况又如何呢？

In the past literature to explore the permanence of such system, the author always assumed the intraspecies density-dependent coefficients of all the species in the system have positive infimum. Obviously, such assumption is far from reasonable in the more superior ecological environment.

以往文献在探讨此类生态系统的持久性时均假设系统内所有种群内部密度制约项系数的下确界恒正，显然此假设在较为优越的生态环境下是不尽合理的。

Lithologies are mostly sand and carbonate rocks, caps are mud rock, shale and magmatite. Entrap types are anticline, fault block rebuilt by breaking and the screened entrap diapered rock mass. The composition is CO_2, N_2, CH_4, C_2H_6 and He etc. It is magma air source body and its geologic fashions are intrusion and buried volcanic conduit. The relations between gas reservoirs and gas source bodies have three types: magma intrusion-breaking-communicated gas reservoir, magma intrusion-contacted CO_2 reservoir and buried volcanic conduit-contacted gas reservoir. The CO_2 migration in magma intrusion is consisted of fusing and crystallizing phases;it in volcanic conduit is consisted of near-surface effusion and crystallizing phases.The buoyancy of CO_2 in water far more than migration resistance in breaking or chink, CO_2 is easy float upward, the floating can results in differentiation of different density gases and concentration of sealed gas. The gas in sand reservoir firstly migrate into the higher porosity and coefficient of permeability sand, and along with the pressure going up it migrate into the lower. In magma intrusion-breaking-reservoir migration, CO_2 firstly migrate into watered breaking, began gravity differentiation and concentrate, the gas pressure time and again go up, CO_2 migrate into reservoir and concentrate under expansibility as the pressure reach upward a given extend. The CO_2 in reservoir experience four breaking modes: chemistry deposition, dissolution, diffusion and mechanic breaking, the pressure balance can be broken by faulting and the CO_2 will further migrate and form new reservoir.

济阳坳陷已发现的八里泊、阳25、平方王、平南、高青、花17 CO_2气藏主要储集层位有奥陶系、中生界、沙四段、沙三段、沙一段、馆陶组和明化镇组，储集层岩性以砂岩和碳酸盐岩为主，盖层以泥质岩、页岩和岩浆岩为主。；圈闭类型主要为受断裂改造的背斜、断块及刺穿岩体遮挡圈闭。；气体成分主要有CO_2、N_2、CH_4、C_2H_6、He等。；主要气源体为岩浆气源体，气源体的主要地质形式为侵入体和埋藏的火山通道。；气藏和气源体的空间关系有岩浆侵入体一断裂一气藏沟通型、岩浆侵入体-CO_2气储集层接触型和埋藏火山通道-气储集层接触型三种类型。；岩浆侵入体CO_2气运移分为熔融运移阶段和结晶运移阶段，火山通道中CO_2气运移分成近地表喷发阶段和结晶运移阶段。；断裂中，CO_2在水中的浮力远大于运移阻力，CO_2气容易上浮，CO_2在断裂中的易浮性导致不同密度气体的分异和走向上封闭的断裂气体相对富集。；气体在砂岩储集层运移聚集具有选择性，会优先进入孔隙度和渗透率较高的砂岩，随着压力增加，才会进入孔隙度和渗透率较低的砂岩；在岩浆气源体-断裂-储集层空间输导格架下，CO_2气在膨胀力的驱动下，首先进入含水的断裂并重力分异而聚集，气体压力会不断增高，当压力增至一定程度，CO_2气会向高孔隙度、渗透率的储集层运移并聚集。；在岩浆气源体-储集层接触空间输导格架下，CO_2气受膨胀力的驱动直接向储集层运移并聚集。；成藏的CO_2气会经历化学沉淀、溶解、扩散和机械破坏四种破坏方式，会受断裂切割而打破压力平衡，沿断裂进一步运移和聚集成藏。
