We found out one kind of new orange-red long afterglow material La2O2S: Eu3+, Mg, Zr.2 In the phosphor Gd2O2S, Mg, Ti which was prepared by high-temperature solid-state method, the orange afterglow phenomenon can be seen after illuminated with UV light.3 Using the high-temperature solid-state method, Gadolinium oxysulfide phosphors doped with rare earth ions were synthesized. We can observe the red or orange phosphorescence in Gd2O2S doped with Eu3+, Sm3+, Tm3+, Yb3+, Dy3+, Er3+, Nd3+or Ho3+. This is a new result of the long afterglow phosphors research.4 Using the microwave radiation method, the new Sm3+ doped gadolinium oxysulfide phosphor, which has the orange-red long afterglow emission after illuminated with UV light or visible light, was synthesized for the first time.5 In fluorescent materials YOX doped with europium ions, the long afterglow phenomenon wasnt observed but the blue luminescence of Eu2+ and red luminescence of Eu3+ are simultaneously examined. This is a new result of the valence stability and change of Eu2+ in yttrium oxyhalide .We systematically studied the effects of the host, addition agents and reaction atmosphere on the valence change and fluorescence property of europium ions.

Result The fiber color was controlled by 4 pairs of genes at least. Whether the long fiber and linter were brown was controlled by a pair of dominant genes separately, the type of its fiber color was controlled by 2 pairs of minor genes at least, showing different types such as light brown and brown approaching white. The long fiber in F2 generation had 3 phenotypes altogether of brown long fiber and brown linter, white long fiber and white linter, white long fiber and brown linter, showing there was interaction among genes and the expression of dominant gene in brown long fiber inhibited the expression of recessive gene of linter color.

The human entire history process, has experienced approximately the primitive migration time, settles down primitively the time, competes barbarically the time, the rank smell of blood exploration time, the knowledge explosion time, the technical restriction time, the belief confused time, then is the humanity finally unifies the return time, in each time, between the humanity both cooperates mutually and opposes mutually, in which migration time, between the humanity struggles the mortality coefficient is 1%, namely in 100 individual deaths has one is because between humanity's conflict indirect or creates directly!

While the tissue spaces surrounding a few blood vessels wasAl and Fg positive,no Al or Fg positive cells were observed.In antemortem injurygroup,diffuse subarachnoid hemorrhage,cerebral edema,swelling or pyknotic neu-rons could be observed.The axons showed irregular swelling and disconnection at1~3h,marked swelling and disconnection at 6h,and retraction ball at 15h whichwas more remarkable at 24h after injury.The space between myelin sheaths andaxons was increased at 3~6h after injury.Tortuous and wavelike myelin sheathswhich adhered on axons incompletely,or even peeled off could be found from 15hto 24h after injury.Perinuclear lysis of Nissl bodies began at 24h after injury.Thenumber of GFAP positive cells in cerebrum and brain-stem increased significantlyfollowed by decrease,and then increased again,but the time courses of the changesin different areas of brain were not same.Al and Fg positive neural cells,mainlysurrounded blood vessels,with diffuse or peripherally distributed positive matter incytoplasm could be observed at 0.5h after injury.The number of Al or Fg positivecells and the intensity of immunoreaction increased with the time of injury.The areaof SYN positivity in medulla oblongata and pons decreased notably 3~6h afterinjury,then return to normal levels and continued to 24h after injury.

Today originally must lead the daughter to visit the university schoolmates to take the thing, but just he once more has the matter to find, temporarily goes to the far east department stores to buy the thing, while convenient leads the wife July the glass tableware birthday gift, this is the 2nd daughter comes here, this time comes human tide not on, possibly crosses the weather after the typhoon not good to have the correlation, but this time feels the daughter temperament compared to an on impetuousness, so long as the cart in has not moved can call, so that I do not stop push on the aisle push, so long as gives the shopping opportunity the wife, wholly absorbed looks after the mood restless daughter, Finally the wife or could not control, bought lovable clothes to put on to the daughter, only was hoped she did not want to be long too quickly.
今天原本要带女儿找大学同学拿东西,不过刚好他再次有事找不到,临时去板桥远东百货逛街买东西,顺便领老婆7月份的玻璃餐具生日礼物,这是第2次带柏妘来这里,这次来人潮没有上次多,可能跟台风过后天气不佳有相关,不过这次感觉女儿脾气比上次浮躁,只要推车没有在动就会叫,以致我不停地在走道上推来推去,只要把购物的机会让给老婆,专心地照顾心情不安的女儿,最后老婆还是控制不了,买了一件可爱的衣服给女儿穿,只是希望她不要长得太快。
