孤岛油田馆1+2砂层组湖相沉积的发现及其意义

分析胜利油区孤岛油田馆陶组上段连续取心井段的岩心,发现了存在浅水湖泊沉积的证据,据此认为馆1＋2砂层组属于浅水湖泊沉积,而非单一的河流相沉积.沉积期间,湖盆地形平坦、水体极浅,湖平面受气候影响频繁振荡式升降变化,沉积物表现为氧化、还原环境交替的红灰相间的细粒结构,湖泊沉积构造（如波状层理、浪成沙纹层理和波痕等）发育.根据岩性、沉积等特征,划分为水道、砂坪、混合坪、泥坪和沼泽等5种沉积微相类型,洪水期和枯水期各微相的发育特点和平面展布不同.馆1＋2砂层组属于湖相的观点为该区的勘探开发提供了新思路.图5参9     

The Intellectual Development of Science and Engineering Students. Part 2: Teaching to Promote Growth

As college students experience the challenges of their classes and extracurricular activities, they undergo a developmental progression in which they gradually relinquish their belief in the certainty of knowledge and the omniscience of authorities and take increasing responsibility for their own learning. At the highest developmental level normally seen in college students (which few attain before graduation), they display attitudes and thinking patterns resembling those of expert scientists and engineers, including habitually and skillfully gathering and analyzing evidence to support their judgments. This paper proposes an instructional model designed to provide a suitable balance of challenge and support to advance students to that level. The model components are (1) variety and choice of learning tasks; (2) explicit communication and explanation of expectations; (3) modeling, practice, and constructive feedback on high‐level tasks; (4) a student‐centered instructional environment; and (5) respect for students at all levels of development.

Occupational Factors and 5-Year Weight Change Among Men in a Danish National Cohort.

This study explored whether factors related to the work environment could predict changes in body mass index (BMI) and whether the effect of psychosocial factors was dependent on baseline BMI. The sample consisted of 1,980 male employees from the Danish National Work Environment Cohort Study. Changes in BMI between 1995 and 2000 were analyzed, by multiple regression, as a function of background variables and a series of occupational variables obtained in 1995. Age, baseline BMI, job insecurity, and psychological demands predicted changes in BMI. Job insecurity and high or low psychological demands increased the likelihood of weight gain among obese employees, whereas they increased the likelihood of weight loss among employees with a low BMI.

XC气田烃类渗漏的生态环境问题探讨

利用中子活化法对四川盆地XC气田的天然气进行分析，发现其中含有20多种金属元素。通过剖面和观察点的观察分析，发现XC气田烃类渗漏，尤其是天然气泄漏对生态环境造成了较大的负面影响：改变浅表生态环境，造成植物生长发育异常，农作牧减产；降低土壤pH值，增加金属元素的水溶态，从而增加植物对其的吸收消化；同时，植物还能从天然气中直接吸收消化一些金属元素。因此，天然气泄漏使农作物吸收消化过多的有毒有害金属，损害农产品品质，应当引起严重关注。
