Because of the fuel-rich propellant's high heat value and combustion temperature, the common stainless steel crucible and oxygen bomb's parts are always burned in the combustion heat testing process. In order to realize the proper testing of combustion heat, some fireproof materials characteristics and their application in the combustion heat testing of fuel-rich propellant were studied. Those fireproof materials include acid washing asbestos, C/C compound materials, Al2O3 chinaware and tungsten crucible.

Nine kinds of compounds are synthesized with NTO〓, PA〓, TNR〓'used as acid radical, and CHZ, SCZ·HCl, AG·H〓CP〓 served as the materials. Among them eight kinds of compounds have been never reported in the literature and one has been prepared at home for the first time. The structures of these compounds are characterized by using the element analysis and the FT-IR measurements.

The results showed that during the 45 days experimental time the fresh weigh of Myriophyllum spicatum L, Hydrilla verticillata L and Cerato-phyllum demersum L were 0.92 g, 0.27 g, 1.11 g and 0.56 g, 0.41 g, 0.87 g in medium nutritional condition TN 1.86 mgL^(-1; TP0.087 mgL^(-1) and eutrophic condition TN 2.47 mgL^(-1; TP0.16 mgL^(-1), respectively. The largest single plant biomass of Myrio-phyllum spicatum L and Ceratophyllum demersum L in in middle nutritional condition were over 39% and 22% higher than those in eutrophicated condition, but that of Hydrilla verticillata L was less than 51%, which shown that Myriophyllum spicatum L and Ceratophyllum demersum L grow better than Hydrilla verticillata L in middle nutritional condition.

研究结果表明，在45 d的培养过程中，狐尾藻、轮叶黑藻和金鱼藻在中营养TN1.86 mgL^(-1； TP0.087 mgL^(-1)和富营养TN2.47 mgL^(-1； TP0.16 mgL^(-1)水平下的单株最大生物量分别是0.92、0.27、1.11、0.56、0.41和0.87 g，狐尾藻和金鱼藻在中营养水平下单株最大生物量分别较富营养水平下高出39%和22%，而黑藻在中营养水平下单株最大生物量较富营养水平下低了51%，表明狐尾藻和金鱼藻在中营养水平下的生长较黑藻好。

Visual carbon stars whose mid-infrared spectra are mainly dominated by photospheric continuum and show large excesses at 60um, represent a transition phase which follows an interruption of mass loss from the oxygen-rich phase and begins a new phase of the mass loss of carbon-rich material. Excesses at 60um in these stars are the emission from the residual of oxygen-rich material.

光学碳星的中红外能量主要来自光球，在60μm处存在超量发射，人们认为其演化阶段处在抛射富氧物质终止和新的富碳拱星壳层形成之间，其60μm超量发射就是富氧物质的残余效应。

Rhyolitic volcanic rocks are generally characterized by rich alkali, silicon, aluminum,and poor calcium, magnesium. They have relatively high Rb,Th and rather low Ba,Sr,Ti,P,and exhibit obviouslv negative europium anomaly (δEu=0.16~0.44).The εNd values of the rhyolitic volcanic rocks range from -5.93 to -2022.Basalts and rhyolites in different cycles show clear geochemical variance.

流纹质岩石总体具富碱、富硅、富铝，贫钙、贫镁特征，其Rb、Th等元素的含量较高，而Ba、Sr、Ti、P等元素含量则明显偏低，并具显著的铕负异常（εEu=0.16'0.44），岩石的εNd值变化于-5.93~~-2.22.I、II旋回玄武岩和流纹岩在地球化学特征上均具明显变异。
