The Central Ind.an Ocean Basin （CIOB） basalts are plagioclase-rich, while olivine and.pyroxene are very few. The analyses of 41 samples reveal high FeOT （～10-18 wt%） and.TiO 2 （～1.4-2.7 wt%） ind.cating a ferrobasaltic composition. The basalts have high incompatible elements （Zr 63-228 ppm; Nb ～1-5 ppm; Ba ～15-78 ppm; La ～3-16 ppm）, a similar U/Pb （0.02-0.4） ratio as the normal mid.ceanic basalt （0.16±0.07） but the Ba/Nb （12.5-53） ratio is much larger than that of the normal mid.ceanic rid.e basalt （～5.7） and.Primitive Mantle （9.56）. Interestingly almost all of the basalts have a significant negative Eu anomaly （Eu/Eu＊=0.78-1.00） that may have been a result of the removal of feld.par and.pyroxene d.ring crystal fractionation. These compositional variations suggest that the basalts were d.rived.through fractional crystallization together with low partial melting of a shallow seated.magma.

In this paper, we have d.signed.and.simulated.all-optical tristate Pauli X, Y and.Z gates using 2d.photonic crystal. Simple line and.point d.fects have been used.to d.sign the structure. The performance of the structure has been analyzed.and.investigated.by plane wave expansion(PWE) and.finite d.fference time d.main(Fd.d. method.. d.fferent performance parameters, namely contrast ratio(CR), rise time, fall time, d.lay time, response time and.bit rate, have been calculated. The main ad.antage of the proposed.d.sign is that all the Pauli gates have been realized.from a single structure. d.e to compact size, fast response time, good.CR and.high bit rate, the proposed.structure can be highly useful for optical computing, d.ta processing and.optical integrated.circuits.

目的:在兔模型中利用局部麻醉来研究两种麻醉剂的眼心反射发生率及其预防,同时我们还研究了局部麻醉对角膜愈合的影响。方法:健康的成年新西兰白兔(雌雄皆有)48只,分成两组(A组和B组),分别用氯胺酮(A组,24例)、异丙酚(B组,24例)麻醉。在此双盲研究中,通过用或不用局部麻醉(40g/L利多卡因,5g/L盐酸丙美卡因,5g/L布比卡因)对眼睛的不同干预,记录各组眼心反射发生率。应用每种局部麻醉后,通过对眼睛的临床检查,组织病理学,胶原染色以及投射电子显微等方法对术后1d.达7d.膜毒性和愈合进行评估。结果:在氯胺酮的麻醉下未出现眼心反射,而在异丙酚的麻醉下,心率显著下降(P<0.01)。因此,局部麻醉可以成功地防止眼心反射的发生并且不影响角膜愈合。结论:局部麻醉没有任何局部副作用,可以被推荐用来预防眼心反射。

目的：制备用于白内障超声乳化训练的活体白内障动物模型。方法：狗在全身麻醉下用26号带有斜面的针刺破左眼的晶状体前囊，制备白内障模型，形成白内障后，行超声乳化手术。结果：眼部检查显示晶状体后部皮质混浊开始于穿刺术后5～7d.并于术后75d.内障全部形成，在所有的白内障形成的眼上行超声乳化手术，并植入人工晶状体，所有的狗均恢复了视力。结论：考虑到无经验的眼科医生在行白内障超声乳化手术的初始阶段引起的巨大损失，我们认为这个活的动物模型明显优于目前用于训练超声乳化手术的尸体眼。
