Objective To investigate the property of the endometrium ion transport in the normal estruation and ovariectomize rats. Methods The basic electrophysiological property of the endometrium was carried out by mean of the short circuit current （Isc） recording with the rats. Results The baseline Lsc and the transepithelial resistance （Rte） were different between the estruation and ovariectomized groups. Apical application of Na＋ channel blocker, amiloride （10 μmol/L）, or CFTR Cl- channel agonist, forskolin （10 μmol/L） did not significantly affect the Lc in the two groups. However, the 1sc in the model group was more sensitive to the CFTR Cl- channel blocker （glibenclamide, 1 mmol/L, apical） decreased about 27.0% （P〈0.05, n=6）, no remarkably changes in the estruation rats. While apical application CA CC CI-channel blocker, DIDS （4, 4 ＇-diisothiocyanostilbene- 2,2 ＇-disulfonic, 100 μmol/L）, the Isc was much more sensitive, percentage almost to 36.52% （P〈0.01） in the model group than that in the control Furthermore, basolateral application of bumetanide （100μmol/L）, a blocker of Na＋-K＋-2Cl- cotransport, didn＇t significantly reduce the Lc in the two groups. Conclusion The baseline Lsc and membrane resistance in the ovariectomize group is much higher than that in the normal estruation group, and the endometrial epithelium CI- secretion may be mediated by predominantly calcium-dependent CI- channels （CACC） and activating adenylate cyclase and apical cAMP-dependent Cl- channels （CFTR） in the model group with minor contributions in the control. Furthermore, the endometrial epithelium responses to different stimulants exists difference in the control and model group a likely mechanism for the ovary hormone.

In order to obtain higher conversion efficiency and to reduce production cost for hydrogenated amorphous silicon/crystalline silicon(a-Si:H/c-Si) based heterojunction solar cells, an a-Si:H/c-Si heterojunction with localized p–n structure(HACL) is designed. A numerical simulation is performed with the ATLAS program. The effect of the a-Si:H layer on the performance of the HIT(heterojunction with intrinsic thin film) solar cell is investigated. The performance improvement mechanism for the HACL cell is explored. The potential performance of the HACL solar cell is compared with those of the HIT and HACD(heterojunction of amorphous silicon and crystalline silicon with diffused junction) solar *** simulated results indicate that the a-Si:H layer can bring about much absorption loss. The conversion efficiency and the short-circuit current density of the HACL cell can reach 28.18% and 43.06 m A/cm^2, respectively, and are higher than those of the HIT and HACD solar cells. The great improvement are attributed to(1) decrease of optical absorption loss of a-Si:H and(2) decrease of photocarrier recombination for the HACL cell. The double-side local junction is very suitable for the bifacial solar cells. For an HACL cell with n-type or p-type c-Si base, all n-type or p-type c-Si passivating layers are feasible for convenience of the double-side diffusion process. Moreover, the HACL structure can reduce the consumption of rare materials since the transparent conductive oxide(TCO) can be free in this structure. It is concluded that the HACL solar cell is a promising structure for high efficiency and low cost.

A series of organic photovoltaic (PV) cells in which the electron acceptor and donor are gadolinium (dibenzoylmethanato)_3(bathophenanthroline) [Gd(DBM)_3bath] and N,N′-diphenyl-N,N′bis(3-methylphenyl)-1,1′-diphenyl-4,4′-diamine [TPD], respectively, were fabricated. Although TPD acts as an active layer in the bilayered cells, insertion of a Gd-complex film between TPD and the alloy cathode is necessary for efficient carrier photogeneration. Open-circuit voltage of 3.2 V was obtained due to efficient exciton dissociation near the interface between Gd(DBM)_3bath and TPD. By incorporating an ultrathin mixed layer of Gd-complex and TPD, external quantum efficiency is improved significantly. Photovoltaic performance of the devices has a common origin, exciplex formation, which results in broadband emission during both photoluminescent and the electroluminescent processes.

A data acquisition system based on LabVIEW is designed and implemented, and electro-discharge(ED) fine truing of metal-bonded fine-grain diamond wheel based on real-time monitoring is researched. Real-time monitoring not only makes efficient impulse specification of ED truing easily obtained, but also is good for timely identifying no-load, avoiding short circuit and arc discharge phenomena and then for obtaining normal machining state. ED fine truing of the fine-grain wheel includes two steps: rough truing for high efficiency and fine truing for high precision. Final ED truing precision and efficiency not only depend on electric process specification, but also is concerned with electrode shape, insulated performance of operating fluid and vertical feed quantity value and frequency. Experiments indicate that ED fine truing based on real-time monitoring can improve the truing precision and efficiency. Average machining efficiency of W10 wheel is about 0.95 μm/min; the final run-out by ED truing is less than 2 μm.

AIM To assess whether higher sensitivity of colonic epithelium to hypoxia at the serosal side is associated with oxygen transfer *** Rats were fed either with normal chow or a lowsodium diet. Tissues were mounted as flat sheets in a modified, airtight Ussing chamber with oxygen meters in each hemichamber. Mucosal samples from normal diet animals were studied under control conditions, in low-chloride solution and after adding chloride secretion inhibitors and chloride secretagogues. Samples from sodium-deprived rats were studied before and after ouabain addition. In separate experiments, the correlation between short-circuit current and oxygen consumption was analyzed. Finally, hypoxia was induced in one hemichamber to assess the relationship between its oxygen content and the oxygen pressure differencebetween both hemichambers. RESULTS In all studied conditions, oxygen consumption was larger in the serosal hemichamber than in the mucosal one(P = 0.0025 to P short-circuit current showed significant correlation with both total oxygen consumption(r = 0.765; P = 0.009) in normoxia and oxygen consumption in the serosal hemichamber(r = 0.754; P = 0.011) during mucosal hypoxia, but not with oxygen consumption in the mucosal hemichamber. When hypoxia was induced in the mucosal hemichamber, an oxygen pressure difference of 13 k Pa with the serosal hemichamber was enough to keep its oxygen content constant. However, when hypoxia was induced in the serosal hemichamber, the oxygen pressure difference with the mucosal hemichamber necessary to keep its oxygen content constant was 40 k Pa(P short-circuit current. This may be partly due to a rectifying behavior of transepithelial oxygen transfer.
