| 1 | Grain Size Distribution and Interfacial Heat Transfer Coefficient during Solidification of Magnesium Alloys Using High Pressure Die Casting Process显示文摘The objective of this study is to predict grain size and heat transfer coefficient at the metal–die interface during high pressure die casting process and solidification of the magnesium alloy AM60. Multiple runs of the commercial casting simulation package, ProCAST^(TM), were used to model the mold filling and solidification events employing a range of interfacial heat transfer coefficient values. The simulation results were used to estimate the centerline cooling curve at various locations through the casting. The centerline cooling curves, together with the die temperature and the thermodynamic properties of the alloy, were then used as inputs to compute the solution to the Stefan problem of a moving phase boundary,thereby providing the through-thickness cooling curves at each chosen location of the casting. Finally, the local cooling rate was used to calculate the resulting grain size via previously established relationships.The effects of die temperature, filling time and heat transfer coefficient on the grain structure in skin region and core region were quantitatively characterized. It was observed that the grain size of skin region strongly depends on above three factors whereas the grain size of core region shows dependence on the interfacial heat transfer coefficient and thickness of the samples. The grain size distribution from surface to center was estimated from the relationship between grain size and the predicted cooling rate.The prediction of grain size matches well with experimental results. A comparison of the predicted and experimentally determined grain size profiles enables the determination of the apparent interfacial heat transfer coefficient for different locations. | P.

| 2 | EFFECT OF REVERT RECYCLE TIMES ON MICROSTRUCTURE AND FATIGUE PROPERTIES IN COBALT-BASE SUPERALLOY K640S显示文摘Effect of revert cycles on microstructure and fatigue properties of cast cobalt base superalloy K640S has been investigated. The results show that: at 70 times of cool heat cycles, there were microcracks found in seven times revert and ten times revert. With the increasing of thermal fatigue cycles, the crack of revert grows a little faster than virgin. When the cycle time reaches 200, the crack length for both virgin and reverts have been as long as 2mm. The low cycle fatigue life has no remarkable change, with the increase of revert cycles at 815℃, 360MPa ,0 5Hz. With the times of cycles increasing, it is found that the content of impurity and gas in alloy change a little, and there is no obvious change for dendrite microstructure. | T.L. Wang 1,2) , J.T.

| 5 | Integration of Known Transcription Factor Binding Site Information and Gene Expression Data to Advance from Co-Expression to Co-Regulation显示文摘The common approach to find co-regulated genes is to cluster genes based on gene expression. However, due to the limited information present in any dataset, genes in the same cluster might be co-expressed but not necessarily co-regulated. In this paper, we propose to integrate known transcription factor binding site information and gene expression data into a single clustering scheme. This scheme will find clusters of co-regulated genes that are not only expressed similarly under the measured conditions, but also share a regulatory structure that may explain their common regulation. We demonstrate the utility of this approach on a microarray dataset of yeast grown under different nutrient and oxygen limitations. Our integrated clustering method not only unravels many regulatory modules that are consistent with current biological knowledge, but also provides a more profound understanding of the underlying process. The added value of our approach, compared with the clustering solely based on gene expression, is its ability to uncover clusters of genes that are involved in more specific biological processes and are evidently regulated by a set of transcription factors. | Maarten Clements Eugene P. van Someren Theo A.

| 8 | 中国某些铁陨石的化学分类显示文摘Based on structural observations and the concentrations of Cr, Co, Ni, Cu, Ga, Ge,As, Sb, Re, Ir and Au by neutron-activation analysis we have classified 14 Chinese iron meteorites. Thirteen are members of the large groups IAB, IIICD, IIICD,IIIAB and IVA.Leshan is an ungrouped iron meteorite that falls within the IIE field on some elementNi diagrams, but is distinctly outside this .fiel on plots of Cu, W, and Ir vs. Ni; it is very similar in Composition to Techado,another ungrouped iron. The high Cu content of Leshan is consistent with other evidence indicating that Cu is a valuable parameter for classifying, iron meteorites. IIICD Dongling appears not to be a new meteorite, but to be paired with Nantan; Dongling was recovered about 50 km from the location of the Nantan shower. Yungning is highly oxidized; we assign it to group LAB but cannot rule out IIICD. IVA-An Longchang has many characteristics of IVA irons, but has been remelted, prebably in a terrestrial setting, Five irons belong to group IVA, a remarkably large number. Three are identical in Composition, and we suspect that the two from Hubei, Guanghua and Huangling, are paired. Thus this set of 14 irons ineludes 12 independent fall. | 王道德 D.J.麦尔文 J.T.沃森 | 1983 | 地球化学1983，12，2： | 3 |

| 11 | HIGH STRAIN RATE SUPERPLASTICITY OF A AIN PARTICULATE REINFORCED 6061Al COMPOSITE显示文摘The superplasticity of AINp/6061Al composite, fabricated by powder metallurgy method and hot-rolled after extrusion, was investigated. The AINp/6061Al composite exhibits an m-value of 0.49 and a maximum elongation of 438% in the strain rates ranging hem 10-2-100s-1 and at temperatures from 823K to 893K. Diffirential scanning calorimeter was used to ascertain the possibility of any partial melting in the vicinity of optimum superplastic temperature. These results suggested that liquid phase existed where maximum elongation was obtained. | L.H. Han, J.T. Niu and D.M.

| 13 | STUDY ON THE PROPERTIES OF DIFFERENT ACTIVATED CARBON FIBERS AND THEIR ADSORPTION CHARACTERISTICS FOR FORMALDEHYDE显示文摘Porous structure and surface chemistry of activated carbon fibers obtained by different precursors and activation methods were investigated. Adsorption isotherms were characterized by nitrogen adsorption at 77K over a relative pressure range from 10-6 to 1. The regularization method according to Density Functional Theory (DFT) was employed to calculate the pore size distribution in the samples. Their specific surface areas were calculated by BET method, micro pore volume and micro porous specific surface area calculated by t-plot method and MPD by Horvath-Kawazoe equation. Micropore volume of rayon-based ACF was higher than that of other samples. The static and dynamic adsorption capacity for formaldehyde on different ACFs was determined. The results show that steam activated Rayon-based ACFs had higher adsorption capacity than that of steam and KOH activated PAN-ACFs. Breakthrough curves illustrated that Rayon-ACFs had longer breakthrough time, thus they possessed higher adsorption capacity for formaldehyde than that of PAN-A CFs. The entire sample had small adsorption capacity and short breakthrough time for water. Rayon-ACFs had excellent adsorption selectivity for formaldehyde than PAN-ACFs. And the samples with high surface areas had relatively high adsorption capacity for formaldehyde. Elemental content of different ACFs were performed. Rayon-based ACFs contained mare oxygen than PAN-ACFs, which may be attributed to their excellent adsorption capacity for formaldehyde. | H.Q. Rong, Z.Y. Ryu and J.T.

| 15 | THEORETICAL STUDY OF HEAT TRANSFER ENHANCEMENT IN PIPE WITH POROUS BODY显示文摘WT5”BZ]A theoretical investigation of the fluid flow and heat transfer in a pipe with porous body of high porosity twisted by metal wire was carried out. A theoretical model of a circular pipe with porous matrix attached at the channel wall and extended inward the centerline was set up. Through analyzing the flow in the porous matrix by the Brinkman-extended-Darcy equation and through including the effect of dispersion by adding the dispersion coefficient into the energy equation, the theoretical solutions of velocity distribution and temperature fields were obtained. Finally the effect of the properties of the porous matrix on the flow and heat transfer in the porous body was studied, which indicates that dispersion can really enhance the heat transfer in pipe.

| 19 | 肝细胞腺瘤相关的基因型-表现型:新的分类及与HCC的关系显示文摘Hepatocellular adenomas are benign tumors that can be difficult to diagnose.To refine their classification,we performed a comprehensive analysis of their genetic,pathological,and clinical features.A multicentric series of 96 liver tumors with a firm or possible diagnosis of hepatocellular adenoma was reviewed by liver pathologists.In all cases,the genes coding for hepatocyte nuclear factor 1α(HNF1α)and β-catenin were sequenced.No tumors were mutated in both HNF1αand β-catenin enabling tumors to be classified into 3 groups,according to genotype.Tumors with HNF1αmutations formed the most important group of adenomas(44 cases).They were phenotypically characterized by marked steatosis(P < 10-4),lack of cytological abnormalities(P < 10-6),and no inflammatory infiltrates(P < 10-4).In contrast,the group of tumors defined by β-catenin activation included 13 lesions with frequent cytological abnormalities and pseudo-glandular formation(P < 10-5).The third group of tumors without mutation was divided into two subgroups based on the presence of inflammatory infiltrates.The subgroup of tumors consisting of 17 inflammatory lesions,resembled telangiectatic focal nodular hyperplasias,with frequent cytological abnormalities(P = 10-3),ductular reaction(P < 10-2),and dystrophic vessels(P =.02).In this classification,hepatocellular carcinoma associated with adenoma or borderline lesions between carcinoma and adenoma is found in 46%of the β-catenin-mutated tumors whereas they are never observed in inflammatory lesions and are rarely found in HNF1αmutated tumors(P =.004).In conclusion,the molecular and pathological classification of hepatocellular adenomas permits the identification of strong genotype-phenotype correlations and suggests that adenomas with β-catenin activation have a higher risk of malignant transformation. | Zucman-Rossi J.
