Isotherms of benzothiophene on the activated carbon were separately measured at different temperature, and then the variation of the adsorption of benzothiophene on the activated carbon was discussed with the help of the hard and soft acid and base principle.

结果表明，活性炭表面负载Ag^＋、Ni^2＋、Cu^2＋或Zn^2＋离子，可提高活性炭吸附苯并噻吩硫化物的能力，而活性炭表面负载Fe^3＋或Co^3＋离子，反而降低了活性炭吸附苯并噻吩硫化物的能力，这主要是活性炭表面的酸碱性质发生变化。

This results in a higher possibility for the components to enter the unstable demixing gap after the rapid phase separation of the system has taken place.Therefore,a bicontinuous structure is easily formed for CA membrane. For the systems of ScCO_2/toluene/PSt and ScCO_2/solvent/PVB,the increase of temperature or decrease of pressure leads to the binodal curves shifting toward the polymer/solvent axes,and thus results in the decrease of miscibility gap.The membrane toplayers of ScCO_2/solvent/PVB systems are dominated by the equilibrium thermodynamics,while the formation of membranes sublayers is the result of the combination of the equilibrium thermodynamics and membrane formation kinetics.

以下时由双节线、旋节线之间构成的亚稳互溶分相区很窄，使得该体系在快速分相后其组成变化进入旋节线内不稳分相区的可能性极高，从而易导致CA膜形成双连续结构；温度升高或压力减小均可导致ScCO_2/甲苯/PSt与ScCO_2/溶剂/PVB两种铸膜体系的双节线向聚合物/溶剂轴一侧靠近，均相区减小；ScCO_2/溶剂/PVB体系的膜表面结构形成主要受平衡热力学过程的控制，而膜的截面结构是其平衡热力学与扩散动力学共同作用的结果。

Results: One case of type A1 (type Weinberg-A), one case of type A2 (type Weinberg-B) and one case of type A3 (abnormal origin of brachiocephalic artery) could be visualized clearly and directly by MSCTA. Morphology of PFAA and its flow disturbance could be seen on echocardiogram in cases of type Al and type A2, although the other case of type A3 was miss diagnosed due to ignoring the suprasternal views.

结果：3例PFAA包括新分型A1型（Weinberg-A型）、新分型A2型（Weinberg-B型）和A3型各1例，螺旋CT血管造影可清晰显示3例PFAA的空间结构及病理解剖，超声心动图能显示2例A1型和A2型的结构及血流动力学变化，1例A3型超声漏诊。

The effect of Zea mays and Bromus riparius on soil and water loss were studied,the experiment was conducted to plant crop and grass in runoff-plots on the 15 degree slope naturally,the bare slop is CK,then the runoff and soil erosion amount and the biological characteristics of corn and meadow bromes termly were measured,and difference of soil and water loss prevention effect on the slop land were determined.The results showed that soil and water loss became less after both corn and meadow brome planting.And the leaf area and the coverage of meadow brome higher than corn,which was benefit for less soil and water loss at the rain season early.Meanwhile,roots of corn and meadow brome mainly distributed in 0-10 cm soil layer,and the root biomass of meadow brome was 2.88 times than that of corn.

试验在自然降雨条件下，在15°坡地设置作物与牧草径流试验小区，以裸地为对照，在每次降雨之后用全深剖面采样器取样，测量其径流量和土壤侵蚀量，定期测定玉米和草地雀麦的生物学特性，研究玉米与草地雀麦生物学特性变化及其坡地水土流失防治效果的差异，探索植物种植对坡地水土流失的主要影响因素，结果表明：种植玉米与草地雀麦，对坡地水土流失均有一定防治作用，但是，与玉米相比，草地雀麦的叶面积指数和覆盖度可在雨季前达到较高水平，有利于早期坡地水土流失防治。

Pleural calcification was missed by chest film but found in 4 by CT. Pleural effusion was noted in 3 by chest film and 4 by CT. HRCT is superior to conventional chest film in demonstrating the changes in the seconday pulmonary lobule such as focal emphysema, interlobular septa thickness and bronchiolar wall thickness.

胸部x光显示肋膜增厚者10例，CT18例，肋膜钙化者无，CT4例，肋膜积水者3例，CT4例，高解像力电脑断层检查更可显示次级肺小叶內的变化如局部气肿，小叶问隔增厚，小支气管壁增厚，这些均优於传统胸部x光片。

We observed changes of GV chromatin configurations in porcine, caprine and bovine oocytes from follicles of different sizes and degrees of atresia and during maturation in vivo and in vitro, using a new method for preparation of GV samples.

本项目发明了一种特殊的卵母细胞生发泡标本制备技术，能克服脂肪滴等对生发泡染色质构型观察的阻碍；经Hoechst或CMA3染色后可清楚地观察染色质构型的变化。

Their adsorption rate on the molecular sieve catalysts surface and the stability of their carbonium ions were then obtained based on the molecular simulation on these molecules from their dipole moment, 2-dimensional electrostatic potential energy contours and 3-dimensional electrostatic potential energy isosurface.

采用半经验的AM1量子化学计算方法和静态理论，分别考察了噻吩、 3 甲基噻吩和 2 ，5 二甲基噻吩分子结构特性的不同，从偶极矩、各自垂直于芳香环平面的二维电势能分布曲线和整个分子周围三维电势能分布情况等方面分析了它们在分子筛催化剂表面吸附速度的快慢和生成正碳离子稳定性的高低，进一步比较了噻吩及其衍生物所生成的正碳离子进一步反应的能量变化，从而可判断噻吩及其衍生物裂化脱硫速度的快慢，噻吩及其衍生物裂化脱硫的速度由大到小分别为：2 ，5 二甲基噻吩、 3 甲基噻吩、噻吩。
