沉积

This is attributed to the infuence of the difference in carbonate mineralogy in different sedimentary environments on the Sr distribution and also to the diagenetic environment which depends upon the sedimentary environment.

究其原因，一方面因不同沉积环境中碳酸盐矿物组分不同，影响了锶的分布；另一方面与沉积环境所决定的成岩环境有关。

Polyimide was patterned by direct laser writing, then the patterned polyimide was immersed in silver diammine solution for seeding. The silver particles were deposited in-situ at the irradiated areas on polyimide films, whose particle size was 150-300nm.

The UV and IR spectroscopic studies of the monomer films showed that the photoreaction ratio of monomer (about 50%) was higher than the corresponding photosensitive polymer (about 10%, PVCi). The polarized IR spectra proved that obvious anisotropic absorption was displayed in the irradiated photosensitive film. With polarizing microscopy method, we found that these kinds of photoalignment films exhibited good alignment ability, and the stability of the photoalignment film could reach about 100℃. 2 A photosensitive self-assembled monolayer was fabricated that contained photo-cycloadditable groups, such as, coumarin and cinnamate. The reaction process were detected by contact angle method because the IR absorption of monolayer was very weak. The photosensitive self-assembled monolayer promote uniform alignment of nematic liquid crystals by LPUV, and it thermal stability could reach about 130℃. 3 A cationic bolaform amphiphiles was synthesized that had two photosensitive double bonds, and can be polymerized by ultraviolet. A layer-by-layer self-assembled deposition film was prepared in aqueous solution by using this material and poly (sodium 4-styrenesulfonate). The UV-Vis. spectra proved that the multilayers film was uniform and layer-by-layer. When LPUV irradiated the film, the photopolymerizable double bond underwent [2+2] cycloaddition, and the production of the reaction distributed along the polarized direction of incident LPUV. Polarized UV-Vis. spectra indicated that the irradiated self-assembled multiplayer film was anisotropic, and the dichromic ration is about 0.09, it is higher than the spin-coating method of photosensitive polymer or monomer. We used this anisotropic film as alignment layer of nematic liquid crystals, and obtained a uniform and stability alignment result, the static contrast ratio is about 100, which is very close to application of liquid crystal device. This thesis is an instance that the photochemical material was used in the physics region of liquid crystals, the route that was from photosensitive monomer, self-assembled monolayer film to self-assembled multiplayer film was undergone, by this logical research method photoailgnment of liquid crystal was extended and consummated.

According to geologic settings, distribution regularities of ore deposit and major metallogenesis in metallogenic belts, it was thought that typical deposits in metallogenic belt of North of Eastern Kunlun is Kendekeke SEDEX-hydrothermal diplogenetic Co, Bi, Au deposit and Baiganhu hypothermal W, Sn deposit, that in metallogenic belt Middle of Eastern Kunlun is Wulonggou orogenic gold deposit, that in metallogenic belt South of Eastern Kunlun is Tuolugou SEDEX Co deposit, and that in metallogenic belt of A'nyemaqen-Bayan Har is Dachang orogenic gold deposit.

通过对各成矿带的地质背景、矿床分布规律和主要成矿作用进行研究，认为东昆北成矿带的典型矿床包括肯德可克热水喷流沉积-热液叠生改造型钴、铋、金矿床和白干湖高温热液型钨、锡矿床；东昆中成矿带的典型矿床是造山型五龙沟金矿床；东昆南成矿带的典型矿床是驼路沟热水喷流沉积型钴矿床；阿尼玛卿-巴颜喀拉成矿带的典型矿床是大场造山型金、锑矿床。

However, this does not disprove that short changes in intensity or direction of the Kuroshio ever occurred at certain short cooling events. The 10Be minimum during the Younger Dryas event may indicate that the Kuroshio had been once greatly weakened or even terminated in the Okinawa Trough area which could be related to the response of the Pacific Ocean to the Younger Dryas. The 10Be and 9Be in surface sediment show totally different distribution patterns. The 10Be distribution is dominated by the input from Kuroshio and its branch, the Yellow Sea Current, whereas 9Be is mainly influenced by terrestrial input of suspended materials from the Yellow River discharge and deposited in the fine-grain size sediment zone southwest of the island of Jeju. Both 10Be and 9Be distribution patterns are different from anthropogenic pollutants such as heavy metal Pb which is dominantly distributed closely to the coastal areas.

冰期时冲绳海槽北部10Be的沉积通量远远高于太平洋大洋海区，充分反映了黑潮的传送带作用和边缘海的聚焦沉积作用，并表明末次冰期时在千年尺度上黑潮仍流经冲绳海槽，且强度并未减弱。10Be的通量在新仙女木时降到整个岩芯所跨时期的最低点，甚至低于10Be的现代大气平均生产率，因此推测在新仙女木事件时，黑潮的变动特别大，有可能改向或断流。

Hitherto mankind has relied on fossil fuel for a major part of its energy supply. Obviously the reserve of fossil fuel is by no means unlimited and will eventually be exhausted after decades. Hence, so far as long-term viewpoint is concerned, it is of importance to utilize the abundant and elean solar energy as an alternative energy source. Stimulated by this objective, studies on the preparation of suitable thin semiconductor films of larger size using simpler methods have attracted increasing interests.

从应用角度看，目前人类利用的矿物燃料其储量终究有限，而太阳能广泛存在，作为一种新型的能源，就长远的现点而言，具有巨大的潜力和广阔的前景，近些年来，研究用简单的方法制备大面积的化合物半导体薄膜材料，越来越受到重视，我们采用电沉积的方法在Ni、Ti以及导电玻璃等基底上沉积了多种硫属化合物半导体材料。

It is made up of two excluding each other ichnocoenosis, namely epibenthic and endobenthic ichnocoenosis; The third one is quite monotony in fossil types, mainly of trails left behind by sediment-eating or detrital-eating animals grazing or feeding along the surfacial layer or on the surface of the sediments.

The former is mainly composed by endogenic traces, with rarely epigenic ones, which is typified by the development of domichnia such as Ophiomorpha, Thalassinoides, Granularia and Palaeophycus, it, in turn, can be divided into predepositional and postdepositional ichnocoenosis.
