Here, however, we can only dabble a bit in using this theme to discuss certain Chinese artists and their works. The artists under discussion have been chosen because they can open up the following issues regarding "things": what things are, how they appear, what relation their appearance has to art, and what the relationships are between things and man and things and society; all of these issues can fall under abstract thinking on thinghood and the specific presentation thereof.

但是在这里，我们只能尝试性地在这一主题下讨论一部分中国艺术家及他们的作品，而之所以选择这些艺术家，是因为他们的作品可以引发以下几个与&物&相关的问题：物是什么，物如何出场，这种出场与艺术有什么关系，物与人、物与社会的关系是什么，这些问题都可以归纳到对物性的抽象思考与具体呈现上。

Methods. PSF 1000 analyzer was used to measure retinal image quality for eye of 26 subjects (spherical ranged from –3.00 ~-6.00Ds, astigmatism ranged from –0.75~-3.00Dc) fitted with three forms of full correction in random order : unaided eye, with rigid gas permeable contact lenses and toric soft contact lenses. The modulation transfer function curve was observed, 12 points of the MTF curve ( equivalent 12 points of LogMar VA) was used for analysis. Results.

Because the top of concrete platform of the carbide furnace has big spans and it carries a heavy load,the scheme of the strengthening concrete with trifurcate beam is used in the structure.

电石炉本体上部钢筋混凝土平台因承受的荷载大、工艺要求的跨度大，采用了劲性混凝土三叉梁的方案，文章针对这一新型结构形式的施工，从方案选择、钢筋接头设置、钢结构制作、灌浆和安装，以及钢纤维混凝土等主要方面进行了介绍。

In this study, nonionic surfactant sorbitan trioleate (Span 85) was modified with Cibacron Blue F-3GA to become an affinity surfactant (CB-Span 85) and to form affinity-based reversed micelles while dissolved in hexane. Since the CB molecule possesses a specific conformation that mimics nicotinamide adenine dinucleotide, it can bind strongly and specifically to a wide range of nucleotide-dependent enzymes such as dehydrogenases and kinases. Moreover, high protein transfer efficiency in the reverse micelles can be easily achieved by controlling the ionic strength of the aqueous phase.

本实验使用非离子型界面活性剂Span 85与蓝色染料分子Cibacron Blue F-3GA结合，形成具有亲和性的界面活性剂 CB-Span 85，由於CB染料分子具有与NAD+相似的结构，可与含核苷酸部位的蛋白质具有亲和力，将CB-Span 85溶於有机溶剂形成反微胞相，可有效的提高反微胞的选择率，可以只控制离子强度来调节蛋白质进出反微胞的效率。

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。
