At first, this age-dating approach was used to estimate the age of G-dwarf stars with Th/Nd chronometry. Recently, it has been used to evaluate the age of halo field stars and globular cluster stars with the Th/Eu and U/Th chronometers.

Methods: The total polysaccharide was extracted with distilled water from mycelia of paecilomyces cicadae. The colorimetric MTT was used to analyze the proliferative activity of PBMC, U937 and K562 which were treated with PCPS of 7 concentrations respectively in vitro. ELISA was used to detect the content of hTNF-α, hIFN-γ from supernatant of culturing PBMC that was treated with PCPS for 44 h.

Typical bands were used to analyze relation with ecotypes and characters of fruits, indicating that there was no relation between typical bands and ecotypes, but some extent relation between bands and characters of fruits existed. If all cultivars were divided into freestone and clingstone, melting and nonmelting, both freestone (ratio shared total survey, 41/56=73.2%) and clingstone (ratio shared total survey, 33/79=41.8%) appeared in the loci of S_(167)-1050 bp linked marker raised by Warburton et al. It was apparently not strong linkage between the marker and the character, and exchange rate of genes was high. If combinations of S_(167)-850bp and S_(167)-1050bp or S_(167)-850bp and S_(167)-1400bp were used to distinguish characters of fruits, 6 freestone accessions without clingstone ones and 6 melting accessions without nonmelting ones displayed in the first combination of markers, 20 clingstone accessions and 2 semi-freestone ones without freestone ones appeared in the second combination of markers.

通过典型带对不同生态型、果实性状为类别进行分析，结果未发现有与生态型相吻合的特征带出现，而将供试所有品种按离核、粘核和溶质、不溶质划分归类，供试品种在Warburton等得到S_(167)-1050 bp处粘离核分子标记，出现既有离核(占供试离核41／56=73.2％)，又有粘核(占供试粘核33／79=41.8％)，可见此连锁标记连锁性不强，发生交换的机率较高，而S_(167)-850bp带和S_(167)-1050bp带同时出现时，该组包含6个离核，无粘核品种；6个溶质，而无不溶质。S_(167)-850bp和S_(167)-1400bp同时出现时，包含20个粘核品种和2个半离核品种。

Methods The rolling coacervation method was used to prepare the sustained-release pellets, and UV was used to determine the release rate.

Linear solvation energy relation was firstly introduced in the paper, and the method and step of gaining the special parameters of solvent and solute were introduced in detail, and these special parameters were used to selection and optimization of extractive agent in extractive distillation. The model of predicting activity coefficient at infinite dilution was established by linear solvation energy relation. By the above theory, several candidate solvents were selected to separate C5 fraction, and by experiment of vapor-liquid phase equilibrium at atmosphere pressure, the mixture of N-methyl-pyrrolidone including 4% water was used extractive agent of separating C5 fraction. Then binary vapor-liquid phase equilibrium of the some compound in C5 fraction and N-methyl-pyrolidone were determined at atmosphere pressure and correlated by NRTL equation. Isoprene being objective compound, experiments were operated in the laboratory-scale column; the processes were simulated by RadFrac model in ASPEN PLUS. And by the combination of experiment and simulation, the new process of separation of C5 was established.
