佛顶山钙铬榴石分布特征及其找矿意义

本区钙铬榴石含钙铝榴石分子，两者组成类质同像系列矿物，颜色和透明度随成分变化而变化。目前找到的钙铬榴石成翠绿色十分美丽。但是，透明者少，粒度均小于４ｍｍ，达不到宝石级标准。但埋于坡积层中的含钙铬榴石铬透辉石岩的转石风化强烈，钙铬榴石易于脱出，晶体保存完整，采选容易，是寻找宝石的理想地区。

Dehydration melting of solid amphibolite at 2.0 GPa: Effects of time and temperature

The dehydration melting of the natural rock at high pressure is important to investigating the magma formation in the earth’s interior. Since the 1970s, a lot of geological scientists have paid more atten- tion to the dehydration melting of the natural rock[1―5]. Previous experiments of dehydration melting and observations of fieldwork argued that the dehy- dration melting of the rock was probably the most important fashion for the melting of the lower crust rock[6―12]. The genesis of most …

The evolution of quasars selected by slitless technique

In former works (Zhouet al., 1983, 1985), a quantitative method have been developed to take the selection effects in the identification of emission lines of quasars into account. It was proved that these selection effects may be the cause of the unevenness in the redshift distribution of quasars. The present work is a continuation and development of former works. We use results given by the surveys with same limit-apparent magnitude and choose the quasars whose absolute magnitudes are within a specific range as the analysing samples. Using the method given in the former papers we may find out the evolutionary parameter in an evolutionary law with form of (1+z) ^y from the best fitting between the calculative and observational redshift distribution. The result of analysis shows that the evolutionary law of quasars selected by slitless technique isp =p ₀(1 + z)^{6.5 ± 1} up toz=2.8. This result coincides with and generalizes the earlier result given by other authors.     

少腹逐瘀丸联合扶阳罐治疗月经不调寒凝血瘀证30例临床观察

目的:研究少腹逐瘀丸联合扶阳罐治疗月经不调寒凝血瘀证的临床疗效。方法:将90 例月经不调寒凝血瘀证患者随机分为治疗组、对照1组、对照2组,每组各30 例。对照1组采用少腹逐瘀丸治疗,对照2组采用扶阳罐治疗,治疗组采用少腹逐瘀丸联合扶阳罐治疗,3组均治疗3个月经周期。比较3组治疗前后中医证候积分,血清性激素［促卵泡刺激素（FSH）、黄体生成素（LH)、催乳素（PRL）、雌二醇（E₂）、孕酮（P）］及血液流变学指标（全血高、中、低切黏度及血浆黏度水平）,评价临床疗效,并比较3组不良反应发生情况。结果：对照1组脱落3 例,对照2组脱落2 例。总有效率治疗组为93.33%（28/30）,对照1组为88.89%（24/27）,对照2组为82.14%（23/28）,治疗组与对照1、2组比较,差异均有统计学意义（P<0.05）;治疗后治疗组中医证候积分、血清性激素指标及血液流变学指标水平均优于对照1组,小腹刺痛、痛经、舌脉积分,血清性激素指标及血液流变学指标水平均优于对照2组,差异均有统计学意义（P<0.01或P<0.05）;治疗后对照1组痛经、舌脉积分,FSH、LH、P、E₂含量,血液流变学指标改善程度均优于对照2组（P<0.01或P<0.05）。不良反应发生率治疗组为3.33%（1/30）,对照1组为7.41%（2/27）,对照2组为0,3组比较,差异无统计学意义（P>0.05）。结论：少腹逐瘀丸联合扶阳罐治疗月经不调寒凝血瘀证疗效较佳,可促进月经恢复正常,调节性激素水平,改善血液流变状态。     

东海大规模赤潮危害影响的实验研究——对黑褐新糠虾和卤虫的毒性效应

The effects of Prorocentrum donghaiense,Karenia mikimotoi,Alexandrium catenella,the causative species of Harmful Algal Blooms in the East China Sea,on the survival and growth of Neomysis awatschensis and Artemia salina were investigated.And the toxicity of eleven strains of Alexandrium----A.lusitanicum(AL-1)、A.minutum(AM-1)、A.spp.(A-K)、A.tamarense(ATHK,ATCI02,ATCI03,AT5-1,AT5-3,AT-6)、A.affine(AS-1,AC-1) to the two above organisms were compared. The results showed that P.donghaiense and K.mikimotoi had no adverse effect on the survival and growth of N.awatschensis and A.salina at 96h.However,the survival rate of N.awatschensis and A.salina declined linearly with the increasing density of A.catenella,and the 96h LC₅₀ for N.awatschensis and A.salina was 4500 and 460 cells/mL,respectively, Five strains of Alexandrium----A.spp,A.lusitanicum (AL-1),A.tamarense(AT5-3,AT-6) and A.affine (AS-1)at the density of 4000cells/mL and 96h had no adverse impacts on N.awatschensis. But other six strains of Alexandrium a.Tamarense(AT5-1,ATHK,ATCI02,ATCI03),A.affine(AC-1) and A.minutum(AM-1)decreased the survival fate of N.awatschensis significantly. Two strains of Alexandrium----A.lusitanicum(AL-1) and A.tamarense(AT-6),at the density of 500cells/mL. had no adverse effects on A.salina in 96h;while the other Alexandrium strains all had adverse effeets on the survival of a.salina, A.salina could increase its length with the increasing density of P.donghaiense,K.mikimotoi and A.luxitanicum. The results indicate that P.donghaiense and K.mikimotoi have nio significant effect on the survival of crustaeean zoop lankton in a short period. But several Alexandrium specised/strains could influence the survival of crustacean zooplankton likely by non-PSP substances. A.salina is shown to be more sensitive than N.awatschensis as test organisms to harmful species.
