论文通过模型试验和数值模拟计算,研究了狭窄沟谷地形、宽坦沟谷地形、岸坡设涵和坡脚设涵四种边界条件下的高填方涵洞土压力随填土高度变化的规律,研究结果表明,在各种边界条件下,高填方涵洞涵顶土压力变化规律相似,当填土达到一定高度后,仍有部分土压力传递到涵顶上,使高填方涵洞的土压力不随填土高度成线性增加,土压力呈非线性变化,高填方涵洞的土压力明显低于理论土压力σ=γH计算值。

The experimental results show that the mean particle size of griseofulvin precipitated by RESS is smaller than 1, 0μm, narrow distribution and 95% fine particles is smaller than 1. 0μm. Increase of the pre-expansion pressure, the extraction temperature, the expansion chamber temperature, the spraying distance, the concentration of cosolvent and decrease of the nozzle diameter resulted in decrease of the particle size under the operating condition studied. Enhancement of the pre-expansion temperature resulted in increase of the particles size. The SEM of GF shows that the shape of original is atactic and a wide size distribution, but the microparticles obtained by RESS is reverse. Similar melting points and XRD patterns were observed for the original material and the precipitates obtained by RESS.
实验结果表明,用含夹带剂的RESS法制备的灰黄霉素微粒的平均直径在1μm左右,且分布均匀,95%微粒在1μm以下,仅用CO〓作为超临界流体制备的微粒与上述方法制备的微粒的平均直径和分布相似,只是产量太低,而用机械法制备的微粒平均直径在3μm左右且分布较宽;不同的过程参数对沉析微粒尺寸有不同的影响,预膨胀压力、膨胀室温度、溶解温度以及夹带剂浓度的提高或增大,均可使沉析微粒的直径变小;预膨胀温度提高,所得微粒的直径变大;喷射距离的增加,沉析微粒的直径变小;喷嘴直径越小,由此制得的微粒的直径就越小;根据实验结果还可知道,通过理论计算的马赫盘处微粒的直径可以较好地估计出膨胀室中收集到的微粒的直径。

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。

Afterwards, the author demonstrates that it is necessary for China to put ecologization of science and technology innovations into practice by combining it with China"s socialism practice on the stage: On one hand, taking account of double challenges that we are facing from internal and overseas whipsaws, the necessity for China to protect environment as well as developing economy has been elaborated and pursuing ecological innovation of science and technology and develop recurrent economy has been thought to be the way of solving China"s environmental problems and enhance her manufacture"s competitive strength in the world. On the other hand, the author shows that it is possible for us to carry on ecologization of science and technology innovations since we have already had some advantages including academic basis in this field, the government"s attention, the evolution actuality of recurrent economy and consumers rouse.

The digital simulation of thedynamic processes under step load input and supply oil pressure fluctuation were carried on by MATLAB. Analysis of the dynamic characteristics was done with the changes of the supply pressure, load, structural parameters of spherical hydrostatic bearing and the effective bulk modulus of oil. The conclusions show that structural parameters of the spherical bearing and the effect bulk modulus of oil have significant influence to dynamic characteristics, but the elasticity deformation of interior supporting collet has very small influences on the output response characteristics of the suspension system. The collets deformation can be neglected on the project.

Because of the low efficiency of economy collectivization, collective property rights can"t last for a long time and central government has to communicate with community and peasants. Rural community collective property rights become subjective through balancing benefits by formal or informal trading. With the changes of political and economical environment, the contradiction of rural community property rights between fair and efficiency become more and more serious. Collective lands and collective enterprises advance to privatization gradually. There are two kinds of country collective property rights in the history of its evolution, one offer community common good and the other satisfy peasants" private demand. The collective property rights institution improvement brings efficiency because it privatizes the latter. Because of the limit of industrialization and civilization, land is still the last social welfare of peasants, so rural community must attain the collective property rights to control the pressure of population. Also community has to get money from collective economy.
本文分析的思路是;由于制度变迁的&路径依赖&,农村社区之间的利益分配边界在解放以后得以保持并在集体化过程中得到加强,为社区获得排他性集体产权奠定了基础;由于国家对农村经济的集体化效率极低而不可能长期维持,国家不得不与社区和农民对话,通过正式或非正式的交易平衡多方利益,社区集体产权获得实质性内容;随着政治、经济等环境的不断变化,社区集体产权公平与效率之间的矛盾同益明显,集体土地和集体企业逐渐朝私有化的方向发展;从农村社区集体产权制度变迁的历史来看,集体产权实际上包含两种形式:提供社区公共物品和满足社区农民个人需求,每一次集体产权的制度创新,都是使后者&私有化&而提高了集体经济的效率;但是,受我国工业化和城市化进程缓慢的制约,土地依然是农民最后的生存保障,农村社区必须保持对土地的集体产权以调节人口变化对土地的压力,社区组织行使职能也必须有一定的集体经济提供资金支持。

Traditional plastic injection molding machine relies on constant rate pump in oil supply, and each action in the process of plastic injection may have different requirements on speed and pressure. The surplus oil flows back to the oil tank through the proportioning valve in the way of flooding adjustment. In the whole process, the rotation speed of motor remains unchanged, so the oil volume is fixed as well. Furthermore, the action is intermittent, and not of full load, so a great amount of oil is wasted.
传统的注塑机是采用定量泵供油的,注塑过程的各个动作对速度、压力的要求也不一样,它是通过注塑机的比例阀采用溢流调节的方式将多余的油旁路流回油箱,在整个过程中,电机的转速是不变的,故供油量也是固定的,而由于执行动作是间隙性的,也并不可能是满负载的,因此定量供油就有很大的浪费空间。
