与石有关的

The LREE enrichment may partly be caused by the presence of microscale LREE-bearing mineral inclusions (such as apatite, monazite or epidote) in the zircons.

对于具有普遍提高的LREE、Th、U、HREE和HFSE含量的海绵状变质锆石，不可能仅仅与常见的热液流体有关。

Cholesterol gallstones formed in C57L mice and fatty livers developed in AKR mice. Conclusions Biliary cholesterol hypersecretion is the key pathophysiological defect of gallstone formation, lith genes have effects on biliary cholesterol hypersecretion and susceptibility to cholesterol gallstone formation in C57L mice. Lithogenic bile is formed at the canalicular membrane and precedes the development of cholesterol gallstones. It is most likely that cholesterol and bile acid hyposecretion make the AKR strain susceptible to the development of fatty livers and resistant to gallstone formation.

结论胆道胆固醇的高分泌是胆囊胆固醇结石形成的主要病理生理基础，结石基因决定了C57L鼠肝内胆汁中胆固醇的高分泌和胆囊胆固醇结石的易患性，成石胆汁形成在肝内胆管，先于胆囊结石的形成；肝内胆汁中胆固醇和胆酸的低分泌可能与AKR鼠脂肪肝的发生和胆囊结石的免患性有关。

Due to the insufficiency of KEYNES and invest-output methods, the authors analyze the increasing of national economy resulting from highway investment multiplicator, propose a theory of calculating highway investment multiplicator based on the original definition of investment multiplicator, and obtain an improved method to calculate th.

为了完善利用公路建设投资乘数计算公路投资对国民经济拉动效益的方法，针对目前利用凯恩斯乘数与投入产出法计算公路建设投资效益的不足，通过公路建设过程中投资乘数作用引起国民经济成倍增长的机理分析，提出从投资乘数的原始定义出发计算公路建设投资乘数的原理，推导了计算公路投资乘数时公路建设投资引起的边际消费的改进算法，并通过京石高速公路有关资料验证了该方法的效果；发展了基于投资乘数计算原理、现有公路工程投资测算、投入产出矩阵组合基础之上的应用方法，克服了常用算法用全社会的消费倾向代替公路投资消费倾向的不足。

Using p-T pseudosections with contours of H20-contents, the medium-low pressure metamorphism for pelite from the Altai orogen was documented. We proposed that the andalusite-type metamorphic zones in Altai were related to the uplifting of kyanite-type zones and are characteristic of isomorphic transformation between aluminosilicates. Generally, it is difficult for the low-pressure metamorphic assemblages to reach an equilibrium state.

利用p-T视剖面图和饱和水含量等值线的行为研究阿尔泰造山带泥质岩石的中低压变质作用发现，阿尔泰地区红柱石型变质带的发生与蓝晶石型变质带的抬升有关，主要发生铝硅酸盐矿物之间的同质多相转变，低压变质矿物组合未能达到热力学平衡状态。

The effectiveness is related to the quality of natural zeolite and other mineral admixtures.

抑制效果与沸石的品质及其他掺合料的品质有关。

Results show that Pb enrichment factors varied from 1.0～1.8 in the cultural layers, and were not quite high. However, with the history going on from the Dawenkou Culture to the Longshan Culture, the Pb enrichment factor displayed an obvious rising trend, which indicated that the Pb in the cultural layers was probably associated with the development of metallurgic activities in the middle stage of the primitive society. From 5 050 cal a BP to 4 000 cal a BP, China underwent Stone Age, Chalcolithic Age and Bronze Age in sequence. Pb dust in the atmosphere increased with intensifying utilization of copper resources, which was probably the main cause of the rising enrichment factor in the cultural layers.

但是随着时间的推移，从大汶口文化到龙山文化，Pb的富集系数有明显逐步上升的趋势，表明遗址剖面中的Pb很可能与原始社会中期发展起来的冶金活动有关。5 050～4 000 cal a BP间，中国先后经历了石器时代、铜石并用时代，到最后进入青铜时代，这个过程中铜资源利用越来越多导致产生的大气粉尘铅越来越多，很可能是YC1剖面中Pb富集系数逐步增长的主要原因。

Moreover, it is easier to control the temperature in the jacketed stirred tank than in the fluidized bed.

而通常结垢问题都发生高温系统，如热交换器等，且本实验室之前在探讨有关磁场对结垢的影响方面，都是在常温下进行，所以本实验将就此重要的变数-温度进行讨论，又由於实验在搅拌槽中进行会比在流化床中进行更容易控制温度，故本实验将在搅拌槽中，探讨磁场与温度对文石成长速率的影响。

Most phytobezoar formation is related to the patient ingestion of persimmon, especially those with previous gastric surgery, autonomic neuropathy or delayed gastric emptying time.

大多数植物性粪石的生成与患者食用柿子有关；尤其是以那些曾经接受过胃部手术或患有系统性疾病合并自主神经病变及胃排空时间延长的患者为然。

Editor: Taiwan ' s stone businessmen have more money, richer international trade and production experience. That ' s why in the later development the Taiwan ' s stone enterprises in mainland reduce at quantity and scale? Do you think it has something to do with Taiwan ' s traders only utilizing the manufacture advantage of the mainland but leaving China mainland this important market aside?

编者：台湾石商有着较为雄厚的资本、丰富的国际贸易和生产经验，但是在后来的发展过程中，台湾在大陆的石材企业无论在数量和规模上都在相对减少，这是否与大部分台商是以出口市场为主，仅仅利用了大陆的制造优势，而忽略了大陆也是全球重要的市场的因素有关？

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
