永8复杂断块油藏水平井地质优化设计

永8块为复杂断块油藏，若全部采用直井开发，不但井网密度大、开采时间长，而且直井防砂后产量低，开发效益不明显。水平井开发的可行性论证认为，出砂的复杂断块油藏适合用水平井开发；水平段应与大断层保持一定的距离且位于正韵律油层的中上部。采用直井和水平井相组合的布井方式，可充分发挥直井钻遇油层层数多和水平井与油层接触面积大、产量高的优势，从而提高复杂断块油藏的开发效果。

Neuroticism and depressive symptoms among spouse caregivers: Do health behaviors mediate this relationship?

This study examined the mediating role of health behaviors in the relationship between neuroticism and depressive symptoms among spouse caregivers. Path analysis was used to test a model of the caregiver stress process among 233 caregivers of people with dementia. Results indicate that neuroticism has a significant direct effect on depressive symptoms and also indirectly influences depressive symptoms through health behaviors and perceived stress. When individual health behaviors were examined in the path model, only physical activity served a significant mediating role. These findings suggest that neuroticism may lead to depressive symptoms among caregivers partly through declines in physical activity.

柴达木盆地断裂系统特征与油气勘探战略方向

基底断裂格局决定了盆地构造演化和沉积发育,导致了北缘、中部和昆北3个各具特色的断裂构造系统。北缘断裂构造系统平面上以反S展布、剖面上以一系列北倾南冲的逆冲断层带及其所控制的同沉积构造呈阶梯向南下掉为特点,受北部祁连山构造应力系统的作用;南部昆北断裂构造系统发育压陷断槽和断阶带,受南部昆仑山构造应力系统的作用;中部断裂构造系统以两断夹一隆的冲起构造为特色,同时受祁连山和昆仑山构造应力的共同作用。断裂对油气藏的形成和分布有重要的控制作用,表现在对烃源岩、储集条件、圈闭形成及油气运聚等方面。依据断裂控烃特征并针对柴达木盆地的具体情况,柴达木盆地油气勘探应迅速转移到盆地腹地即中部断裂构造系统区,尤其是鄂博梁Ⅱ号一伊克雅乌汝、鸭湖—台吉乃尔构造带和中南隆起区,有望取得重大突破。

Physicochemical and Functional Properties of Freeze-Dried and Oven Dried Corn Gluten Meals

The physicochemical and functional properties of convection oven- and freeze-dried gluten meals of two corn varieties were evaluated. The physicochemical properties (water solubility index, water absorption index, Hunter color parameters, and bulk density) and functional properties (water absorption, oil absorption, least gelation concentration, protein solubility, and emulsification properties) of convection-oven and freeze-dried corn gluten meals were compared with each other and soy flour. Freeze-dried corn gluten meals was observed to have lower bulk density (0.244-0.263 kg/m³) and was lighter in color (high L and ΔE) compared to their counterpart convection oven-dried gluten meals. Freeze-dried gluten meals from both corn varieties showed significantly higher oil absorption, water absorption, pH, emulsification, and protein solubility compared to oven-dried corn gluten meals. The gluten meals from both corn varieties had lower water absorption and bulk density but higher oil absorption than soy flour, suggesting the hydrophobic nature of corn proteins. Corn gluten meals formed thin (pourable) emulsions compared to soy flour emulsions, which were thick salad dressing type. Freeze- and convection oven-dried corn gluten meals showed significantly lower protein solubility measured at different pH than soy flour.     

FeBP非晶态合金超细微粒的合成及其对PH3分解的催化作用

用化学还原法合成了FeBP非晶态合金超细微粒，用电感耦合等离子体光谱（ICP）、X射线粉末衍射（XRD）、透射电子显微镜（TEM）和差热分析（DSC）等手段对其进行了物性表征，并用微型催化反应装置考察了其对PH3分解的催化作用，结果表明，非晶态合金FeBP对PH3的分解具有良好的催化作用，能使PH3的分解温度从800℃以上降到500℃左右。490℃时分解率超过90％，540℃时达100％。     

Feasibility study of absolute activity measurement with metallic magnetic microcalorimeters

We report on a feasibility study on precise determination of mass-specific activity of low-energy emitting radioisotopes. Conventional methods of activity measurement suffer from source self-absorption and a strong decrease in detection efficiency for low-energy electrons and photons. We propose a new method based on metallic magnetic microcalorimeters with the source embedded in the detector target in a 4π geometry. First results with a ⁵⁵Fe source show that electrons and photons are detected with a detection efficiency close to unity and with little loss of energy for electrons. The aim of this study is to provide standards of activity with very low uncertainties in the framework of radiation metrology.     

Effects of Surface Concentration on Drying Behavior of Carbohydrate Solutions

As the surface properties of the drying materials are very important not only for the drying rate but also for the quality change during drying, the effects of surface concentration on the drying behavior of liquid foods (sugar solutions) were investigated by isothermal drying experiments and by numerical calculation experiments. The isothermal drying experiments with gelled sugar solution systems (sucrose and maltodextrin) were carried out at various relative humidity (RH) values (RH = 0 to 84%). Separate experiments were carried out for determination of the desorption isotherms.

The isothermal drying curves of sugar solutions at RH = 0 to 51% were very similar. Numerical simulations also showed that the drying curves of these sugars at the surface concentration = 0 and 0.1 are almost the same, although the concentration distributions are different.

When a small amount of gelatin was added to sugar solutions, the drying rate decreased remarkably as the gelatin might form a thin film (skin) near the surface, and consequently the retention of ethanol increased.
