What form tremendous contrast with afore-mentioned opinion on public affairs is, yo ever stated the company already was planning to finish work of generation lead plane before Yves Guillemot of green jade president two days, strive for heavy dice to bet expected affection to be in overtones again, the power that proves dynastic changes once more comes from only possibly suffer from not all small or petty proprietor and beggarly estate, like EA this kind of landlord moneybags that insists green hill to be not loosened is only too anxious to all one's life so generation lead plane.

与上述言论形成巨大反差的是，育碧总裁Yves Guillemot前两天曾表示公司已在规划下一代主机作品，争取重掷骰子再赌一把的期盼之情溢于言表，再度证明改朝换代的动力只可能来自患不均的小业主和赤贫阶层，像EA这种咬定青山不放松的地主老财巴不得一辈子就这么一代主机。

KIR bind corresponding HLA-Ⅰmay hame four results followed:1、When inhibitory KIR bind HLA-Ⅰand there has no activatory KIR bind it,cell isn\'t dissolve because inhibitory signal access was done;2、When activatory KIR bind corresponding HLA-Ⅰand there has no inhibitory KIR bind it,form activate signal,lead cell dissolve.3、If activatory or inhibitory receptor both bind HLA-Ⅰ,both signal access is make done,when activatory signal play the main role,NK cell still actived,lead target cell dissolve.4、If activatory or inhibitory receptor both bind HLA-Ⅰ,both signal access is make done,when inhibitory signal play the main role,or both signal access don\'t play,NK cell do not make effect.this is NK cell recognice nomal tissue.

与活化型KIR受体相比，抑制型KIR受体与HLA-Ⅰ类抗原结合的亲和性更强，当抑制型和活化型KIR受体识别和结合同一HLA-Ⅰ类抗原分子时，以抑制作用为主。KIR与相应HLA-Ⅰ结合后可能产生以下4种情况：①当抑制型KIR与HLA-Ⅰ结合而无活化型KIR与HLA-Ⅰ相互作用时，因抑制信号通路启动而不产生细胞溶解；②当活化型KIR与靶细胞表面的相应HLA-Ⅰ结合同时无抑制型KIR与HLA-Ⅰ的相互作用时，形成刺激信号通路，导致靶细胞溶解。

Also re-estimate le- ad battery's operating environment and also find out the common in between different lead battery fac- tory, position, gender, and employee's blood lead and hemachrome concentration, liver function expo- nent.

本研究将以变异数分析研究血中铅浓度在不同工厂别、作业别、性别间、工作月数是否达显著差异，并了解在不同作业类别间，何类别之员工血中铅浓度最高。

For leting drop quality fuel plenty of normal heptane have no lead tetraethyl ,Therefore be unlikely there not be the lead pollution .

这样：既没有多余的空气，混合相当充分、又不存在高温，更没有燃烧中相对的压缩，所以不可能产生不完全燃烧的CO、HC、PM和氮氧化物。

The method comprises:(1) weighing lead acetate hexahydrate and thioacetamide, and preparing aqueous solutions respectively, so that the concentration ratio of Pd2+ to S is 1:(1-4);(2) adding acetic acid into thioacetamide solution to adjust the pH value to 2-4;(3) adding poly surfactant into lead acetate solution, ultrasonicating to mix uniformly and obtain a colorless and transparent sol;(4) mixing the sol and thioacetamide solution;(5) placing the mixed solution in a sealed container, irradiating by 2.5 MeV and 40 mA electron accelerator with irradiation dose of 25-40 Mrad;(6) washing the product, centrifuging for separation, and drying to obtain black PdS nanoparticles.

本发明方法的工艺过程如下：首先称取一定量的六水合醋酸铅和硫代乙酰胺，各自配制成水溶液，其浓度比为使其中的铅离子浓度与硫原子浓度的比例为1∶1～1∶4；在硫代乙酰胺溶液中加入适量醋酸调节其pH值至2～4；醋酸铅溶液中加入少量表面活性剂聚乙烯醇，然后超声振荡，混合均匀，制成无色透明溶胶；随后将溶胶与上述的硫代乙酰胺溶液混合；将该混合液置于密闭容器中，并将其放置于2.5MeV、40mA的电子加速器产生的电子束辐照下进行辐照处理，其辐照剂量为25～40Mrad；然后将反应生成物清洗，并用高速离心机离心分离，然后干燥，最终得到黑色纳米硫化铅颗粒。
