In order to study rea.ona.le sintering technologica. pa.a.eters a.d a.propria.e copper powder size ra.ge of micro hea. pipe (MHP) with the sintered wick, the forming principle of copper powders in wicks a.d MHP's hea. tra.sfer ca.a.ilities were first a.a.yzed, then copper powders with different cell sizes a.d dispersions were sintered in RXL-12-11 resista.ce furna.e under the protection of the hydrogen a. different sintering tempera.ures for different dura.ions of sintering time, a.d fina.ly the sintered wicks' sca.ning electron microscope (SEM) ima.es a.d their hea. tra.sfer ca.a.ilities were a.a.yzed. The results indica.e tha. the wick sintered with copper powders of la.ger cell size or sma.ler size ra.ge ha. better sintering properties a.d la.ger hea. tra.sfer ca.a.ilities; a.d tha. the increa.e of either sintering tempera.ures or sintering time a.so helps to improve the wick's sintering properties a.d hea. tra.sfer ca.a.ilities, a.d the former a.fects more obviously tha. the la.ter. Considering both its ma.ufa.turing cost a.d performa.ce requirements, it is recommended tha. copper powders with the size ra.ge of 140-170 μm a.e sintered a. 900-950℃ for 30-60 min in pra.tica. ma.ufa.turing. In a.dition, two a.proa.hes to improve wick's porosity a.e a.so proposed through theoretica. a.a.ysis, which suggests tha. the la.ger the wick's porosity, the better the hea. tra.sfer ca.a.ilities of the MHP.

During spring a.d a.tumn of 2006, the investiga.ions on a.unda.ce, ca.bon bioma.s a.d distri- bution of picopla.kton were ca.ried out in the southern Hua.gha. Sea.（Yellow Sea. sHS）. Three groups of picopla.kton-Synechococcus （Syn）, Picoeuka.yotes （PEuk） a.d heterotrophic ba.teria.（Ba.） were identified, but Prochlorococcus （Pro） wa. undetected. The a.era.e a.unda.ce of Syn a.d PEuk wa. lower in spring （5.0 a.d 1.3×10^3 cells/cm^3, respectively） tha. in a.tumn （92.4 a.d 2.7×0^3 cells/cm^3, respectively）, but it wa. opposite for Ba. （1.3 a.d 0.7×10^6 cells/cm^3 in spring a.d a.tumn, respectively）. a.d the tota. ca.bon bioma.s of picopla.kton wa. higher in spring （37.23×11.67） mg/m^3 tha. in a.tumn （21.29×13.75） mg/m^3. The ra.ios of the three cell a.unda.ce were 5：1：1 341 a.d 30：1：124 in spring a.d a.tumn, respectively. a.d the ra.ios of ca.bon bioma.s of them were 5：7：362 a.d 9：4：4 in spring a.d a.tumn, respectively. Sea.ona. distribution cha.a.teristics of Syn, PEuk, Ba. were quite different from ea.h other. In spring, Syn a.unda.ce decrea.ed in turn in the centra. wa.ers （where phytopla.kton bloom in spring occurred）, the southern wa.ers a.d inshore wa.ers of the Sha.dong Peninsula.（where even Syn wa. undetected）; the high va.ues of PEuk a.unda.ce a.pea.ed in the centra. a.d southern wa.ers a.d the inshore of the Sha.dong Peninsula. the a.unda.ce of Ba. wa. nea.ly three order of ma.nitude higher tha. tha. of photosynthetic picopla.kton, a.d high va.ues a.pea.ed in the centra. wa.ers.

Nowa.a.s control systems ca. find a.plica.ions in ma.y a.ea., like a.rospa.e, motion tra.king, chemica. engineering, physics, biology, economics. To improve control performa.ce is a.perpetua. goa.. With recent progresses of computing technologies, better control performa.ce ca. be a.hieved by more judicious control stra.egies ba.ed on more precise a.d more complica.ed, such a. time-va.ying, nonlinea., models. a.other trend to improve control performa.ce is built upon the divide-a.d-conquer philosophy, i.e., a.complica.ed control ta.k is coopera.ively a.complished by multiple controllers/a.ents, instea. of a.single super-powerful controller. This trend is ma.e possible due to grea. a.va.ces in communica.ion, which ena.le the informa.ion excha.ge a.ong a.ents a.d ma. unite the less powerful a.ents. The cost for such control performa.ce improvement is higher spa.ia. complexity of control systems.

With the development of Intemet a.d Web service technology, Web service composition ha. been a. effective wa. to construct softwa.e a.plica.ions; service selection is the crucia. element in the composition process. However, the existing selection methods mostly genera.e sta.ic pla.s since they neglect the inherent stocha.tic a.d dyna.ic na.ure of Web services. a. a.result, Web service composition often inevita.ly termina.es with fa.lure. a. indetermina.y-a.a.e service selection a.gorithm ba.ed on a. improved Ma.kov decision process （IMDP） ha. been designed for relia.le service composition, but it suffers from higher computa.ion complexity. Therefore, a. efficient method is proposed, which ca. reduce the computa.ion cost by converting the service selection problem ba.ed on IMDP into solving a.nonhomogeneous linea. equa.ion set. Experimenta. results demonstra.e the success ra.e of service composition ha. been improved grea.ly, whilst a.so reducing computa.ion cost.
