Response to Dersarkissian's comments on the structure of the Universe

We found that the structure of the Universe can be characterized by a set of actions ^s . This means that some discontinuous phenomena in the Universe can be considered as large-scale quantum effects. The behaviour of matter on a typical scale is determined by the behaviour of matter on other scales through the interactions.     

The evolution of quasars selected by slitless technique

In former works (Zhouet al., 1983, 1985), a quantitative method have been developed to take the selection effects in the identification of emission lines of quasars into account. It was proved that these selection effects may be the cause of the unevenness in the redshift distribution of quasars. The present work is a continuation and development of former works. We use results given by the surveys with same limit-apparent magnitude and choose the quasars whose absolute magnitudes are within a specific range as the analysing samples. Using the method given in the former papers we may find out the evolutionary parameter in an evolutionary law with form of (1+z) ^y from the best fitting between the calculative and observational redshift distribution. The result of analysis shows that the evolutionary law of quasars selected by slitless technique isp =p ₀(1 + z)^{6.5 ± 1} up toz=2.8. This result coincides with and generalizes the earlier result given by other authors.     

Emission line redshift distribution of QSOs

This paper is the second one of a series of papers on the redshift distribution of QSOs. In this paper, we shall study the influence of the selection effect in the identification of emission lines on the redshift distribution of QSOs more thoroughly than the previous paper (Zhouet al., 1983). If we assume that the QSO's redshift is cosmological, adopt the standard model, and consider the selection effect due to the redshift identification, the limiting apparent magnitude in the observation and the evolutionary effect of QSOs, we can compute the emission line redshift distribution for the so-called optically selected QSOs discovered by objective prism, grating prism technique alone, the QSOs discovered by positional methods or by colour technique and for whole QSOs, respectively (see Figures 6, 11, 12). The results of computation agree with the observations very well, especially for optically selected QSOs; the computational distribution has almost the same shape with the observational one. For this kind of the QSOs the computational distribution may give the positions and heights of all these observed peaks. The correlation coefficient between the calculated and observed distributions is larger than 0.95. It shows that (a) the peaks and dips in the redshift distribution of QSOs are mainly caused by the selection effect in the redshift identification, and (b) the redshift of QSOs is cosmological.

南海西部海域新生代构造古地理演化及其对油气勘探的意义

南海西部海域构造复杂,主要发育有北东—北东东向、北西向和近南北向3组深大断裂。其中,北西向断裂与板块汇聚、碰撞有关,多具走滑性质;北东—北东东向断裂具有与中国东部裂谷盆地相似的发育特点,呈张扭性质;近南北向断裂可能是南海在扩张活动期间于洋、陆壳过渡部位形成的走滑调节断裂,是洋盆扩张的西部边界。新生代里,南海经历了4次成盆事件与3期扩张活动,盆地经历了古新世—中始新世陆缘断陷、渐新世—早中新世扩展与中中新世以来的热沉降3个演化阶段。陆缘断陷阶段的充填系列主要是北东—北东东向与北西向的河流—冲积扇、湖泊沼泽等陆相沉积及火山岩等;盆地扩展阶段表现为中-小型断陷、断-坳陷逐渐复合与联合为大-中型坳陷,古地理格局逐渐由河流与湖沼陆相环境演变为滨海至浅海相的沉积环境;热沉降阶段的成盆活动逐渐减弱以至停止,地层表现超覆,盆地出现联合迹象。结合以往勘探与油气资源调查成果分析,认为南海西部海域陆架陆坡区发育的大-中型沉积盆地石油地质条件良好,蕴藏着丰富的油气资源,勘探潜力巨大。     

祁连山不同植被类型对积雪消融的影响

为研究祁连山植被对积雪消融的影响, 利用人工调查积雪深度逐日变化量和积雪盖度变化, 并结合空气雪面感热通量(SH)观测, 对祁连山水源林生态站排露沟流域海拔2 600～2 700 m青海云杉林、灌丛林、林缘、阳坡草地在2003-2007年的积雪消融进行了研究, 每年的观测从10月降雪开始到翌年5月积雪消融完结束, 共获取数据134 400个. 结果表明: 当SH<0时, 积雪消融停止;当SH>0时, 积雪消融开始;植被可以减缓积雪消融速率, 有植被的地方消融速率减慢, 反之则加快;不同植被消融速率大小顺序为草地>林缘>灌木林>乔木林;同一植被、不同坡向消融速率不同, 半阳坡云杉林＞半阴坡云杉林＞阴坡云杉林. 积雪含水率随气温升高而增大, 1月融化积雪占整个积雪的5%, 2月增大到28%, 大量积雪在3月消融, 占55%. 从坡位看, 下坡消融速率最大;在一个垂直带上, 低海拔消融速率大于高海拔. 温度是影响积雪消融的主要因子, 积雪消融速率随温度升高而增大, 反之则减小.     

胶东三甲金矿床流体包裹体特征

三甲金矿是胶东牟平-乳山金成矿带内重要的石英脉型金矿,金主要产于黄铁矿和多金属硫化物石英脉中。流体包裹体研究表明,三甲金矿蚀变岩石和各成矿阶段金矿石中的流体包裹体主要有三种类型：H2O-CO2包裹体、富CO2包裹体和H2O溶液包裹体。早期乳白色石英中主要赋存原生的H2O-CO2包裹体;成矿期黄铁矿石英脉和多金属硫化物石英脉中的富CO2包裹体主要为原生,随机分布,气液比变化较大,常与早期H2O溶液包裹体共生且均一温度接近,显示不混溶流体包裹体组合特征;在成矿晚期的石英和方解石中主要发育原生H2O溶液包裹体。显微测温结果显示,成矿前（第1阶段）H2O-CO2包裹体的完全均一温度（Tb．TOT,至液相）为280℃至416℃,成矿期（第Ⅱ和Ⅲ阶段）富CO2包裹体的完全均一温度为210—330℃,同期的H2O溶液包裹体均一温度为253～377℃,成矿后（第Ⅳ阶段）H2O溶液包裹体的均一温度为176—207℃。成矿流体为低盐度的CO2-H2O-NaCl型热液,成矿应力场转变导致的流体减压沸腾作用可能是三甲金矿金沉淀成矿的主要原因。
