After adding different metal compounds (K2CO3, NaCl and Al2O3), the sludge ignition point had a certain drop and the characteristics combustion index are also changed, indicating the combustion performance of the sludge was improved. Different metal compounds behave different katalysis at different combustion stage. And K2CO3 performs stronger catalytic capacity than that of NaCl and Al2O3 in the whole process.

污泥添加不同金属化合物K2CO3、NaCl和Al2O3后，其着火点有一定的下降，对污泥的燃烧有促进作用；不同金属元素化合物的加入对污泥燃烧性能有一定的改善，并且在燃烧的不同阶段金属化合物表现出不同的催化能力，其中K2CO3的催化性能强于NaCl和Al2O3。

Under these conditions, the yield of cyclohexanone glycol ketal could be reach 90.4%, indicating that rare earth composite solid superacid SO4(superscript 2-)/ZrO2(superscript 3+) is a good catalyst for the synthesis of cyclohexanone glycol ketal.

在此条件下，缩酮收率可达90.4%，说明稀土复合固体超强酸SO4(上标 2-)/ZrO2/Gd(上标 3+)是一种合成环己酮乙二醇缩酮的优良催化剂。

Based on the findings in the comparative study of immune parameters between Chinese shrimp Fenneropenaeus chinensis and Kuruma prawn Marsupenaeus japonicus, this thesis firstly carry on the researches of iNOS activity in shrimps, and find it a reliable parameter for indicating the disease resistance ability in shrimps. The results here could offer a sound scientific basis for the better understanding of the mechanism of shrimp disease resistance ability to WSSV infection, as well as the development of countermeasures for the disease control in shrimp culture industry.

本文在系统比较两种对虾感染WSSV病毒过程中抗病力指标变化的基础上，优选出与WSSV感染直接相关的抗病力指标，并首次对对虾的一氧化氮合成酶进行了系统的研究，所得到的结果为深入了解对虾对白班综合症病毒的抗病力机制，并建立和发展相应的病害防御措施提供了科学依据。

It can be concluded that WSSV infection can stimulate the iNOS synthesis in shrimps. However, the enzyme activity decreased sharply after the proliferation of virus. Therefore, iNOS can be considered as a valuable index for indicating the health status of Chinese shrimp F. chinensis and Kuruma prawn M. japonicus. In comparison with Chinese shrimp F. chinensis, the iNOS in the haemocytes of Kuruma prawn M.

我们通过NBT还原法和血细胞形态法在中国对虾和日本对虾血细胞中鉴定到了iNOS，并通过亚硝酸盐法和L-瓜氨酸法对比研究了感染WSSV后这两种对虾血细胞中iNOS的变化情况，结果显示：在WSSV感染初期，WSSV可以诱导中国对虾和日本对虾产生iNOS，且日本对虾比中国对虾的iNOS更容易被LPS所诱导。

The result showed that all the males copulated successfully with the females within one week, indicating the male fertility was not affected after gestational and lactational exposure to endosulfan.

出生后90-95天，将每组10只成年雄性仔鼠与另外健康成年雌鼠按1∶1同笼交配，每天查阴栓以判断雄性生育力，结果各组动物都在1周内成功交配。

The photopolymerization led to stable latices and they were obtained with neither coagulation during synthesis nor destabilization over time. It was found that the obtained MMA homopolymers exhibited relatively narrow molecular weight distributions(PDI=1.27—1.36), which was characterized by GPC. The plots of number-average molecular weight vs. conversion and ln([M0]/) vs. time were linear respectively, indicating that the reaction was a controlled/living free radical polymerization.

结果表明，该细乳液体系非常稳定，在整个聚合过程中即没有絮凝物产生，也没有沉淀析出，获得了良好的ln([M0]/)与时间、数均分子量与转化率之间的线性动力学关系，并且在整个聚合反应过程中MMA均聚物的分子量分布比较窄，其多分散性指数较低(PDI=1.27~1.36)，具有明显的活性聚合特征。

To check the abilities of Zn uptake and accumulation of duckweed (Lemna minor Linn.), experiments of growth, Zn accumulation and SOD activitial response to Zn in plant duckweed were performed with fresh plant in vivo. The results showed that growth of duckweed was affected by 5 mg/L Zn treatmenat in solution, indicating better resistance to Zn.

为探询浮萍对水体Zn的吸收富集能力，为水体Zn污染的植物修复提供依据，采用水培方法对浮萍的Zn的吸收富集特性及生物量、抗性进行分析，同时也对Zn处理条件下，浮萍体内SOD酶活性变化进行了测定。

From otoliths, the spawning times of these three species are all estimated to occur much later in the year than when small leptocephali are found at sea, indicating that ages appear to be underestimated.

从耳石来看，这三种鳗的产卵时间按照耳石推断出来都比实际发现柳叶鳗的时间要晚一些。

But the basic results had inercommunity that both the precipitation of last summer and relative moistuer from September to October in last year, indicating that the increment of Larix leptolepis associated with precipitation and groud temperature of spring closely in the area.

创新点在于：本研究依据15株日本落叶松解析木资料及10项气象因子资料，采用逐步回归及关联度分析法较系统地探讨了影响豫西日本落叶松生长的气象因子，为日本落叶松引种、栽培及抚育管理提供重要依据。
