A 50-year Porites lutea core from Nansha Islands (9°33′N, 112°54′E) was analyzed for δ〓O and δ〓C for two aims. First, we hope to find and set up some formula between δ〓O and environmental parameters, such as thermometer readings, so that we can reconstruct historical environment of this area. Second, we hope to understand the climate changing process during the past fifty years of this area and its relation to the global change.

本文以南沙群岛永暑礁的滨珊瑚Porites lutea为研究对象，通过质谱分析，研究珊瑚月分辨率δ〓O、δ〓C记录的环境信息，旨在为进一步重建南沙群岛过去高分辨率的环境变化提供一个类似于温度计的标尺；还重建了永暑礁器测时期以前40年高分辨率的环境变化过程，旨在了解南沙群岛气候变化过程及其与全球变化的关系。

Results: The cultured chondrocytes were polygonal cells. There were many rough endoplasmic reticula and mitochondria in cytoplasm, and a lot of secretory vesicles under cell membrane and in the cytoplasm. When cultured for 10 days, some small and white nodules were formed on the bottom of the culture dished, and volcanic-mouth-like structures were formed when cultured for 20 days. Both these nodules and structures contained GAG-positive substances were demonstrated by safranine-O staining.

RESULTS: The respiratory control rate and P/O ratio decreased gradually as rectal temperature increased. When Tr rosed to ＞42℃, RCR and P/O ratio decreased by 31.4% and 11.05%( P ＜0.05) respectively.RCR decrease resulted mainly from the effect of respiratory state Ⅳ.

结果：热应激大鼠心肌线粒体呼吸控制率(respiratory control ratio， RCR)及氧化磷酸化效率均随动物直肠温度的升高逐步显著降低，当大鼠直肠温度超过42℃时，RCR与P/O分别较对照下降31.4%，11.05%。

And 5. 4～8. 5‰, respectively. Nonequilibrium oxygen isotope fractionation between rock-forming minerals and the low H〓O content indicate that depletion in D-〓O of the A-type granites from eastern China is the result of magma degassing and subsolid interaction between meteoric water and rocks.

主要造岩矿物对氧同位素不平衡分馏和全岩低水含量特征指示中国东部A型花岗岩D-〓O亏损主要受岩浆去气作用和岩浆期后大气降水亚固态交换的制约。

In contrast to the granular shape papillaes around the stomata and less density of trichoma on costal zones in tetraploidies of O. officinalis, the triangle and overarching shape papillaes, and denser trachoma were observed in diploidies.

在O。 officinalis中，四倍体有粒状气孔器外围乳突和脉带表皮毛较少，二倍体细胞型具有三角形拱状排列的气孔器外围乳突和较密集的脉带表皮毛；而在O。

The cause of hard agglomerate formation and its effect on sinterability were investigated. The water-washed ZrO〓-Y〓O〓 powders were found to be greatly made up of hard agglomerates. The ethanolwashed powders also contained a few of hard agglomerates because of uneffective dehydration. Beside, ethanol volatilizes in advance of water during drying because ethanol has a lower boiling point than water, so steric effects of ethanol won't act. However, nearly no hard agglomerate formed in the azeotropic distilled powders, because of effective dehydration and higher boiling point for n-butanol.

研究指出，水洗工艺所得ZrO〓-Y〓O〓粉末几乎完全由硬团聚组成；乙醇洗涤工艺的脱水效果不是很好，并且由于乙醇的沸点比水低，以致在干燥过程中残留乙醇比水先挥发，乙醇的空间位阻效应不能有效地发挥作用，因此，仍然可以导致产生一定量的硬团聚；而共沸蒸馏工艺的脱水效果最佳，且正丁醇的沸点比水高，干燥时残留正丁醇比水后挥发，从而正丁醇的空间位阻效应可有效地发挥作用，因此避免了在煅烧过程中形成Zr-O-Zr键，即共沸蒸馏粉末中不含硬团聚。

It was found that the central metal ion is located at the symmetric center of the molecule. Four oxygen atoms from two H2O molecules and two 〔C6H4(CO2)2〕2- groups are coordinated with copper ion to form a similar planar square coordination configuration. There is one only unidentate coordination bond between O(1) in 〔C6H4(CO2)2〕2- and Cu2+.

结构分析发现，中心金属离子位于分子的对称中心位置，铜离子与来自2个水分子和2个邻苯二甲酸根中的4个氧原子形成近似正方形平面配位，邻苯二甲酸根是以1个O(1)与Cu2+离子形成单齿配体，O(2)和Cu2+之间没有形成配位键。

Results show that the wear rate of O'-Sialon-ZrO2-SiC is much less than that of stainless steel at the testing condition, and main wear mechanism of the unlubricated friction is adhesive wear .

研究表明，在实验条件下，O′－Sialon－ZrO2－SiC复合材料的磨损率远低于不锈钢的磨损率，O′-Sialon-ZrO2－SiC／不锈钢摩擦副间的磨损机制主要是粘着磨损。

Apparent different thermal behaviors between micro-PS and o-PS were observed during DSC scan: micro-PS displayed an irregular exotherm aboveglass transition and an exotherm of about 6.4 J/g at around 157 ℃ during the firstscan, and only one glass transition similar to o-PS was shown in the subsequent scan.

具体表现为两者在热行为方面的差异：第一次DSC扫描过程中，micro-PS出现两个放热峰，第一个不规则且与玻璃化转变重叠，第二个在157 ℃；而第二次DSC扫描则仅表现出与o-PS一样的玻璃化转变。

Among them the red blood cells of O type were agglutinated best and the HA titers reached 213.The virus contents of artificial infected rabbits had been determined for different visceral organs.
