CL imaging has identified two types of zircon that are metamorphically new growth and recrystallized detrital grains, respectively.

文章摘要：大别-苏鲁造山带大理岩中榴辉岩包体的锆石有两种类型，为变质增生锆石和变质重结晶的残留碎屑锆石。

The diffusion of ethanethiol in MFI and MOR was investigated by Molecular Dynamics.

采用分子动力学方法模拟计算了乙硫醇分子在MFI和MOR两种拓扑结构沸石中的动力学性质，比较了乙硫醇不同负载量和沸石晶格原子刚性和柔性两种状态下乙硫醇分子在沸石孔道中扩散系数的大小。

TiO2/sepiolite and TiCVzeolite with high photocatalytic activity have been prepared using sepiolite and zeolite minerals as carrier and the industrial metatitanic acid and the industrial sulfate titanium liquid as the raw materials for the first time.

首次采用工业偏钛酸、工业浓钛液为原料，天然海泡石、沸石为载体，制备出具有光催化活性的复合材料；沉积在海泡石或沸石表面的TiO_2粒子晶型为锐钛型；制成的TiO_2／海泡石、TiO_2／沸石复合物比表面积分别达到255m~2／g、161m~2／g； 2。

Magnesia alumina spinel brick is based on high-purity magnesia and synthetic magnesia alumina spinel with major crystal phase of periclase and spinel. By intensively mixed, double-face pressed and fired at high temperature. Being completely chrome free, it is the ideal refractory for the transitional zone of cement kiln characterized by superior thermal shock resistance, good anti-erosion capacity, and lower thermal conductivity.

此次展会为您展出的水泥回转窑用镁铝尖晶石砖以高纯镁砂和合成镁铝尖晶石砂为主要原料，主晶相为方镁石和尖晶石，经过强力混练，双面加压，高温烧成等工艺制成，是水泥窑过渡带的标准耐火材料，具有无铬污染，热震稳定性好，耐磨损，抗侵蚀性强，热导率低等特点。

First, organic pillared montmorillonite were prepared in which three kinds of organic quaternary ammonium salts were used as pillaring agent. Physiochemical properties of organic pillared montmorillonites were characterized by XRD, FT-IR, TG-DTA. Furthermore their characters that have been testified are excellence.

首先用三种有机季胺盐作为柱撑剂制各出有机柱撑蒙脱石，并通过XRD、FT-ZR、TG-DTA等测试手段对其进行了表征，并且对制备的有机柱撑蒙脱石进行了性能测试，证明其性能优良，说明利用干法制备有机柱撑蒙脱石是切实可行的。

Objective To compare the therapeutic effects of laparoscopy and open ureterolithotomy in the treatment of ureterastone and investigate the management pringciples of retroperi to neal laparoscopic ureterolithotomy.

目的 比较腹腔镜输尿管上段切开取石术与开放性输尿管上段切开取石术的疗效，并探讨腹腔镜经腹膜后途径行输尿管上段切开取石术的处理要点。

The contents of other metal elements Na, Mg, K, Al, Mn and Pb in lagenal otoliths were not significantly different from those in utricular and saccular otoliths.

瓶状囊耳石中其它金属元素Na、Mg、K、Al、Mn、Pb的含量与球囊和椭圆囊耳石相比无显著性差异，但Zn、Ba、Cu的含量低于球囊耳石。

The contents of other metal elements Na, Mg, K, Al, Mn and Pb in lagenal otoliths were not significantly different from those in utricular and saccular otoliths.

瓶状囊耳石中其它金属元素Na、Mg、K、Al、Mn、Pb的含量与球囊和椭圆囊耳石相比无显著性差异，但Zn、Ba、Cu的含量略低于球囊耳石。

The contents of metal elements Zn, Ba and Cu in lagenal otoliths were lower than those in saccular otoliths. Conclusion The contents of magnetic elements in lagenal otoliths of homing pigeons are not much higher than those in utricular and saccular otoliths, which does not support the hypothesis that birds depend on high contents of Fe and Zn in lagenal otoliths for sensation of geomagnetic information.

结果表明成年信鸽瓶状囊耳石中磁性元素的含量极低而且不比内耳球囊和椭圆囊耳石更丰富，从而不支持信鸽因其瓶状囊耳石中含有较高的Fe、Zn等元素而能够感受地球磁场这一假说。

Two Xylaria strains isolated from the stem of Dendrobium fimbiratum and leaf of Dendrobium brymerianum were identificated by morphology and molecular biology.

对石斛内生炭角菌进行鉴定及活性成分初步研究。从流苏石斛的茎和长苏石斛的叶片中分离出两株炭角菌，将其编号为lsjz和csyz。

I will endeavour to find you some assistance.

我尽力帮你找人帮忙。

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
