针对喷雾液滴在靶标上接触角测量的重现性不佳等问题，以玻璃和石蜡模拟靶标表面，研究了去离子水在亲水和疏水靶标表面上液滴体积和测量时间对接触角测量的影响，结果表明：液滴体积越大接触角越小，这种趋势在亲水表面比疏水表面上更突出，测量时体积可分别选择在0.5~1μl和1~5μl；液滴滴下30-50s后与固体表面基本达到平衡，对接触角测量的准确度影响较小。

The analysis result shows that the remaining oil of this area is characterized as: Remaining oil is mainly distributed in thin tabulated beds and untabulated beds with low permeability. Remaining oil scatters widely. Complexity exists in the contact between remaining oil and water flooded layers and zones. Vertically, the remaining oil layers in adjusting area alternates with water breakthrough layers, between them the barrier beds is thin. Horizontally, because of the plane heterogeneity, the relatively good intervals are flooded, so that the remaining oil only exists in margin oil layer owing to faultiness of injection-production; remaining oil is enclosed by waterflooded zone, therefore, it is so complex relationships between remaining oil and waterflooded layers and zones that high requirements are made in the choice of completion optimization.

通过研究分析，研究区二类油层剩余油具有以下特点：(1)剩余油以表内薄差层和表外层为主，渗透能力低；(2)剩余油比较零散；(3)剩余油与水淹层和水淹带的接触具有复杂性；调整区剩余油从纵向上看，剩余油层与见水层相间分布，隔层小；从平面上看，由于油层平面的非均质性，相对较好部位已水淹，只在油层的边边角角部位由于注采不完善等因素存在剩余油，剩余油被水淹带包围，所以目前剩余油与水淹层和水淹带的接触相当复杂，这对完井方式的选择提出更高的要求。

Basic characteristics and prevailing genetic models of Chondrites have been introduced and commented. Unusu-al features of Chondrites from the Lower-Middle Ordovi-cian transition have been reported in the west-central Utah, USA. They include that tiny Chondrites -were cut by other trace fossils associated with them and formed in softground, and that Chondrites were the earliest or shallowest tiering in the complex ichnofabrics.

介绍和评述Chondrites的基本特征和流行的成因解释，记述最近发现于美国犹他州中西部北美下-中奥陶统之交层型剖面上的Chondrites遗迹组构的不寻常特征和属性：细小的Chondrites被所有与之共生的遗迹化石交切，形成于水与沉积物界面附近缺氧的早期软底质中，Chondrites是形成最早和最浅的遗迹阶层。

瀑水跌落在水潭中低凹的石面上，石面被瀑水猛烈地冲击，反射出丹砂一般的红光。

A broad expanse of the river was turned to blood;1 in the middle distance the red hue brightened into gold, through which a solitary log came floating black and conspicuous;2 in one place a long, slanting mark lay sparkling upon the water; in another the surface was broken by boiling, tumbling rings, that were as many-tinted as an opal; where the ruddy flush was faintest, was a smooth spot that was covered with graceful circles and radiating lines, ever so delicately traced; the shore on our left was densely wooded, and the somber shadow that fell from this forest was broken in one place by a long, ruffled trail that shone like silver; and high above the forest wall a clean-stemmed dead tree waved a single leafy bough that glowed like a flame in the unobstructed splendor that was flowing from the sun.

不远处红光闪成金黄；孤零零的一根原木在河中漂浮而来，呈一线醒目的黑色；河的一处，一条长长的斜影横落在水面上，闪闪烁烁；另一处，水面被翻滚的水波打碎，仿佛蛋白石放射的斑斓色彩；红彩最淡处是一片平静的水面，覆盖着优雅的环形和放射状的波纹，细腻如绘；河左岸是一片浓密的森林，一条长长的崎岖小径划破树林的一片荫翳，闪闪如银；一株光秃秃的枯树高耸于密林之上，仅剩的一杆青枝随风摇曳，像火焰闪耀在阳光洒下的一览无遗的壮美之中。

还记得自己刚开始船上生涯时所见过的那次辉煌的落日：宽阔的河面一片血红；不远处这红色明亮起来，变成金色，一根显眼的黑色圆森木从中漂过；这边，一根长长的浮标倾斜在水面上，熠熠闪光；那边，翻滚的波浪打破了宁静的水面，像猫眼石般色彩纷呈；微红的水流最缓和处，美丽的涟漪在平稳的水面上层层荡漾开去；左侧的河岸上丛林茂密；一条如银带般闪亮的小径从昏暗的树荫中蜿蜒而出，伸向远处；高高的密林之上有一根无枝无蔓的枯树，仅留有一根带叶的树枝在风中晃动，在太阳一泻千里的光辉里，它宛如燃烧的一团火；还有优美的波纹、水中的倒影、树木葱茏的高地、柔和的远景；放眼望去，由远及近，逐渐裉去的光线随波荡漾，每时每记得都以其新的奇妙着色为这条河添姿增彩。

The study of the mineralization degree ,water type and ion combination coefficient of the Pre-Tertiary formation water in Chaluhe fault depression,Yitong Basin,reveals that total mineralization degree of the water is relatively low,and NaHCO3 water type,while the formation water has obvious vertical mineralization zonation with a high metamorphic grade.

对伊通盆地岔路河断陷古近系地层水的矿化度、水型及变质系数、脱硫系数的研究表明，该区地层水总体为NaHCO3型水；总矿化度偏低；平面上，孤店斜坡的油气保存条件最差，梁家构造带最好，垂向上，具明显的垂向分带性，万昌组保存条件最差；变质程度高。

The morphological analysis and chemical characterization of the worn surfaces via scanning electron microscopy, laser scanning microscope, and X-ray photoelectron spectroscopy reveal that under titrimetric water lubrication, the hBN in Si3N4-hBN spalled off during the wearing tests and the spalled pits formed on the wearing surface of Si3N4-hBN, and then the debris dropped into the pits to react with water, thus a tribochemical film formed on the wearing surface. The formation of the tribochemical film facilitated smoothing the surfaces of Si3N4-hBN and Si3N4 to create a fine lubrication environment.

在滴定法水润滑条件下，磨屑不易被水带走，当Si3N4-hBN与Si3N4配副摩擦时，由于Si3N4-hBN摩擦面上hBN偏聚区域发生脆性断裂和剥落而形成剥落坑，磨屑在剥落坑中堆积并氧化、水解，反应产物富集于剥落坑中，进而在摩擦表面形成含B2O3和SiO2的摩擦化学反应膜，从而保护了Si3N4-hBN和Si3N4摩擦面，使其变得光滑，为发生流体润滑提供了条件。
