In the Large Helical Device （LHD）, two different divertor configurations, i.e. helical divertor （HD） and local island divertor （LID）, are utilized to control the edge plasma. The HD with two X-points is an intrinsic divertor for heliotron devices, accompanied with a relatively.thick ergodic lay.r outside the confinement region. Edge and divertor plasma behavior from low density.to high density.regimes is presented, referring to the divertor detachment. The effect of the ergodic lay.r on the edge transport is also discussed. On the other hand, the LID is an advanced divertor concept which realizes a high pumping efficiency.by.the combination of an externally.induced magnetic island and a closed pumping sy.tem. Experimental results to confirm the fundamental divertor performance of the LID are presented.

The results on high power injection with the ueutral bean, injection （NBI） sy.tem for the Large Helical Device （LHD） are reported. The sy.tem consists of three beam-lines with two hy.rogen negative ion （H^- ion） sources installed in each beam-line. In order to improve the injection power, a new beam accelerator with a multi-slot grounded grid （MSGG） has been developed and applied to one beam-line. Using the accelerator, a maximum power of 5.7 MW was achieved in 2003 and 2004, and the maximum energy.of 189 keV was reached. The power and energy.exceeded the design values of the individual beam-line for LHD. The other beam-lines also increased their injection power up to about 4 MW, and the total injection power of 13.1 MW was achieved with three beam-llnes in 2003. Although the accelerator had an advantage in high power beam injection, extracted beams expand in the short side direction of the ground-grid slot. The disadvantage has been resolved by.modify.ng the aperture shapes of the steering grid.

The mechanical properties of the Mg97Znly. extruded alloy.containing the long-period stacking ordered phase, the so-called LPSO-phase, with a volume fraction of 24%-25%, were examined by.compression tests and cy.lic tension-compression deformation tests. The plastic behavior of the extruded alloy. with compositions of Mg99.2Zn0.2y..6 and Mg89Zn4y. （molar fraction, %）, which were almost the same compositions of Mg matrix phase and LPSO phase in Mg97Zn1y. Mg/LPSO two-phase alloy. respectively. were also prepared. By.comparing their mechanical properties, the strengthening mechanisms operating in the Mg97Zn1 y. extruded alloy.were discussed. Existence of the LPSO-phase strongly.enhanced the refinement of Mg matrix grain size during extrusion, which led to a large increment of the strength of alloy. In addition, the LPSO-phases, which were aligned along the extrusion direction in Mg97Zn1y. extruded alloy. acted as hardening phases, just like reinforced fibers.

利用一个紧凑的铯沉积系统对用于大型螺旋装置-中性束注入（LHD-NBI）系统的1/3比例氢负离子源的内表面进行直接的沉积，试验了在3-200mg范围内小的、很确定的铯量的沉积，在纯氢运行模式和有铯模式下都进行了负离子的引出和加速。对等离子体室单纯的3-30mg的铯沉积使H∧-产额暂时增高2-5倍，但是在几个放电脉冲之内该产额又降低到原先的稳态值。在3-5h/60次放电间隔之内连续两次的30mg沉积，产生了类似的H∧-的瞬时增长，但达到很大的H∧-产额的稳态值。在20-120h/150-270次放电的间隔内，更大量的0.1-0.1gGs的沉积，在一个长的运行周期（2-5d）内改善了H∧-产额。对等离子体室各个壁的定向的Cs沉积表明了近似同样的H∧-的增加。对被水泄漏污染的表面沉积0.13gGs产生了与单一30mg铯沉积时相类似的H∧-的瞬时增加和H∧-的稳态水平，用铯等离子体的0.1g沉积得到了用相同量的铯原子沉积时获得的H∧-产额的一半。与在相同的放电功率下12根灯丝运行相比，在8根灯丝的放电运行期间记录到更高的稳态H∧-流值和更小的H∧-产生速率。

众所周知,共析点的锌—铝二元合金,具有较高的阻尼(减震)性,但因其强度低而未被应用。作者开发了压铸用的锌—铝合金,其商标为Cosmal—Z,或称科斯马耳锌—铝合金。由于在此合金中添加了硅、铜和锰,提高了强度,但又不降低其固有的高阻尼性。这些合金中,ZM—11含Al 22%,ZM—3含Al 40%和超利斯马耳含Al 60%。ZM—1在室温时、ZM—3在高达100℃时、以及超科斯马耳在高达150℃时,均有很高的强度和振动阻尼特性。此外,这些合金在压铸时有很好的铸造性能,与现有的铝压铸合金相比,用科斯马耳高阻尼性合金生产薄壁压铸件是可能的。

AIM： To clarify.the clinicopathological significance of laminin-5 y. （LNγ2） and 133 （LNI33） chains and MMP7 expression in biliary.tract cancer. METHODS： We analy.ed the association between immunohistochemically.detected LNγ2, LNβ3, and MMP7 expression in biliary.tract cancer and clinicopathological characteristics. Activity.of MMP7 was analy.ed by.casein zy.ography. An in vitro invasion assay.after treatment with MMP7-specific siRNA was performed. RESULTS： LNγ2 expression was predominantly.observed in carcinoma cells at the invasive front. LNγ2 expression was seen in 57% of patients with biliary.tract cancer, and was associated with depth of invasion, histologic ty.e, and advanced stage. The expression pattern of LNβ3 was classified Into two ty.es： invasive front dominant ty.e （38%） and diffuse ty.e （28%）.The invasive front dominant ty.e was associated with histologic ty.e and advanced stage. MMP7 positivity.was correlated with LNγ2 or LNβ3 expression but not with clinicopathological characteristics. Active MMP7 detected by.casein zy.ography.was correlated with depth of invasion and advanced stage. Downregulation of MMP7 expression by.siRNA resulted in a significant decrease in biliary.tract cancer cell invasion in ***： Our results suggest that LNγ2 and LNβ3, in conjunction with MMP7, play.a key.role in the progression of biliary.tract cancer.
