Comparison of Taste Components between Triploid and Diploid Oyster

The main taste components of triploid and diploid oyster (Crassostrea gigas) were compared. Free amino acids, inosine monophosphate, succinate, trimethylamine oxide and betaine in fresh and boiled extractives were analyzed. The protein, lipids, glycogen, moisture and ash, which may affect the flavour, were evaluated. In boiled extractives, the amino acids were 394.1 mg(100g)^-1 in diploid and 183.5 mg(100g)^-1 in triploid. However, in fresh oyster extractives, they were 320.0 mg(100g)^-1 and 147.3 mg(100g)^-1 respectively. The inosine monophosphate in triploid was 44% more than that in diploid, and a little difference existed in the content of trimethylamine oxide between them. The contents of these taste components were the basis for taste flavour pattern determination.     

含平流（avdection）的热单温吸积流的径向结构

本在小粘滞参数，低吸积率的条件下，借助含平流的热吸积流的自相似解，考虑非热正负电子对产生，采用分两个区域分别求妥然后对接的方法，研究了含平流的热单温吸积流的径向结构。证实了热吸积流所具有的一些显特征和基本性质，同时得到一些新的结果：含平流的热吸积流存在一个临界半径ｒＣｒ；明确指 出含平流的热吸积流的辐射冷却率与中心天体的质量成平方反比关系；提出正负电子对过程对含平流的热吸积流的辐射过程有显影     

太阳表面米粒结构观测对比度分析

分析以观测系统焦面上和探测器测到的太阳表面米粒结构的对比度与观测系统口径，大气湍流相干长度以及系统探测灵敏度的关系，给出了不同口径，不同大气湍流相干长度以及不同系统探测灵敏度时的米粒结构对比值计算结果，此外还给出了实验结果。     

试论高校负债发展中的筹资风险及其控制策略

高校发展中的适度负债是解决制约高校超常规发展的有效方式，但高校在使用负债资金实现办学目标时，却存在巨大的风险。控制负债筹资风险的策略是：1．把握现实，转变观念，树立风险意识；2．确定适度的负债结构，降低资金成本；3．正确把握负债的数量与规模，保持合理的负债比率，提高偿债能力；4．强化预算管理，建立控制风险和抵御风险的内部机制。

On the Period Variation of the W UMa-type Contact Binary V502 Ophiuchi

The variation in the orbital period of the W UMa type contact binary V502 Oph is analyzed. The orbital period exhibits a wavelike variation with a periodicity of 23.0 years and an amplitude of △P = 1.24×10~(-6) days superimposed on secular decrease of dP/dt = 1.68×10-7 day per year. The long-term decrease may be accompanied by the contraction of the secondary at a rate of 83 m per year and a mass transfer rate from the primary to the secondary of 4.28×10~8 M per year. The short-term oscillation may be explained by the presence of a third component. Orbital elements of the third body and its possible mass are presented.     

The comparison between allozyme and RAPD makers for the population genetic structure analysis of scallop Chlamys farreri

1INTRODUCTION Since the first use in human genetic research in1966,allozyme has become the most popular genetic marker for population genetics studies for almost all groups of animals and plants(Lewontin and Hubby,1966;Murphy et al.,1996).In the past seve…
