Thi. study i.vesti.ated the mi.rostructural characteri.ti.s, metallurgy, mi.rohardness, and tensi.e strength of AZ31 and AZ61 magnesi.m alloy weldments, fabri.ated i. a CO2 laser weldi.g process wi.h the adjustment of vari.us parameters. The results show that the AZ31 weldment contai.s equi.xed grai.s wi.hi. the fusi.n zone （FZ）. By contrast, the FZ of the AZ61 weldment contai.s refi.ed cellular grai.s and the parti.lly melted zone （PMZ） contai.s bulk grai.s. We i.fer that the di.ference i. alumi.um content between the two magne-si.m alloys results i. di.ferent supercooli.g rates and soli. grai. structures. For both weldments, the ulti.ate tensi.e strength （UTS） de-creases followi.g the CO2 laser weldi.g process. However, no si.ni.i.ant di.ference i. noted between the UTS of the two weldments, sug-gesti.g that tensi.e strength i. i.sensi.i.e to the Al content of the magnesi.m alloy. The CO2 laser weldi.g process i. shown to i.crease the mi.rohardness of both magnesi.m alloys. Furthermore, grai. refi.ement i. responsi.le for the maxi.um hardness i. the FZ of both weld-ments. The AZ61 weldment has a hi.her content of Al, resulti.g i. a greater grai. refi.ement.

Ai.： To assess the i.ci.ence of and ri.k factors for gallstone di.ease （GSD） among type 2 di.beti.s i. Ki.men, Tai.an. METHODS： A screeni.g program for GSD was performed by two speci.li.ts who employed real-ti.e abdomi.al ultrasound to exami.e the abdomi.al regi.n after pati.nts had fasted for at least ei.ht hours. Screeni.g, whi.h was conducted i. 2001, i.volved 848 pati.nts di.gnosed wi.h type 2 di.betes. After exclusi.n of 63 subjects wi.h prevalent GSD, 377 parti.i.ants wi.hout GSD were i.vi.ed i. 2002 for a second round of screeni.g. A total of 281 （74.5%） subjects were re-exami.ed. RESULTS： Among the 281 type 2 di.beti.s who had no GSD at the fi.st screeni.g, 10 had developed GSD by 2002. The i.ci.ence was 3.56% per year （95%Ci. 1.78% per year-6.24% per year）. Usi.g a Cox regressi.n model, age （RR = 1.07, 95% Ci. 1.00-1.14）, wai.t ci.cumference （RR = 1.12, 95% Ci. 1.01-1.29）, and ALT （RR = 1.13, 95%Ci. 1.01-1.26） appeared to be si.ni.i.antly correlated wi.h development of GSD. CONCLUSi.N： Older age i. a known ri.k factor for the development of GSD. Our study shows that greater wai.t ci.cumference and elevated ALT levels are also associ.ted wi.h the development of GSD among type 2 di.beti.s i. Ki.men.

Laboratory ani.als mai.tai.ed on a reduced calori. but nutri.i.nally adequate di.t have extended li.e spans and lowered i.ci.ences of spontaneous and chemi.ally i.duced cancers compared to ad li.i.um- fed counterparts. Many of the effects of di.tary restri.ti.n on laboratory ani.als have been suggested to be related to a decelerati.n of the agi.g process. The i.hi.i.i.n of age-related changes i. xenobi.ti. metaboli.i.g enzyme acti.i.i.s by di.tary restri.ti.n has previ.usly been reported. Alterati.ns of these enzyme acti.i.i.s may cause changes i. metaboli. acti.ati.n of carci.ogens and, therefore, carci.ogen-DNA bi.di.g. DNA-repai. capabi.i.y has also been reported to be enhanced i. di.t-restri.ted rats. Usi.g AFB1 as a model carci.ogen, we have studi.d i. vi.o and i. vi.ro hepati. AFB1 -DNA bi.di.g, demonstrati.g that di.tary restri.ti.n (60% of ad li.i.um consumpti.n) may decrease the metaboli. acti.ati.n of AFB1, and subsequently reduce AFB 1-DNA bi.di.g. Our preli.i.ary results obtai.ed from the AFB 1-DNA bi.di.g experi.ents i. i.olated hepatocytes suggest that the observed age-dependent reducti.n i. AFB 1-DNA bi.di.g whi.h may be attri.uted to a loss of metaboli. acti.ati.g capabi.i.y was delayed i. the di.t-restri.ted rats.

Thi. paper presents a small power generati.n system moti.ated by a coreless stator AFPM (Axi.l Flux Permanent Magnet) generator whi.h i. dri.en by the rooftop venti.ator. The generator consi.ts of di.cs for the rotor and the stator geometry. The stator di.c i. sandwi.hed between two rotor di.cs and the magnets i. the two opposi.e rotor di.cs may be placed N-S arrangements. Si.ce there i. no si.i.on steel i.si.e the coi.s, we should eli.i.ate the magneti. pulli.g force between the rotors and the stators. When the venti.ator rotates, the flux of the permanent magnet rotors part move across the ai. gap and i.duces the emf i. the coreless coi.s. After that, the ac voltage i. recti.i.d to dc voltage and fi.ally charged to the 12 V 5 Ahr battery for household appli.nces. To analyze the magneti. ci.cui., the fi.i.e element analysi. was used to si.ulate the magneti. flux densi.y i. the AFPM generator. The test i. operated i. electri.al machi.es laboratory and essenti.lly to determi.e the characteri.ti.s of prototype generator. Based on the experi.ents, the results of the output voltage can achi.ve 103 V wi.h no-load, and 20 V on 100 Ω resi.ti.e loads at the speed of 200 rpm. For the results after i.stalli.g the generator on the roof of a bui.di.g to charge the 12 V battery, the mi.i.um wi.d speed for enough chargi.g to battery i. at 10 rpm. Furthermore, the prototyped of the generator i. relati.ely small and cheap. After the fabri.ati.n and testi.g of the prototype, thi. system has been proved feasi.le for practi.al appli.ati.n.

水合物形成于相对低温高压环境,这种条件下对水合物形成后的流体中残留的甲烷浓度进行直接的原位观测非常困难。本文在高压透明腔体中成功合成了甲烷水合物,利用拉曼光谱技术在低温高压条件下对水合物形成过程中流体中残留的甲烷浓度的变化进行了原位观测,用拉曼峰面积比值法获得了三个温度、压力下水合物形成后的饱和甲烷浓度值。研究发现,水合物生长过程中,流体中的甲烷被不断消耗而浓度逐渐降低,温度对水合物形成后的流体中残留的饱和甲烷浓度影响很大,温度越低,残留的饱和甲烷浓度越小,与通常条件下甲烷在水中的溶解度随温度的降低而增加的趋势正好相反。
