OBJECTIVE: To evaluate the short-term safety and outcome of 2 different experimental applications of rasburicase 0.2 mg/kg in patients with tophaceous gout not treatable by allopurinol.

目的：评价别嘌呤醇治疗无效的白垩性痛风患者应用拉布立酶0.2毫克/公斤的2个不同实验的短期的安全性和疗效。

Field geological investigation, petrology and geochemistry study showed that three oil shale groups in Kazuo basin were developed in Member 1,2,3 of the Jiufotang Formation of Lower Cretaceous, the third oil shale group located in 3rd member have the greatest industrial significance. Oil shale always has the accompanying relationship with overlying sedimentary tuff or other tuffaceous strata.

野外地质调查和岩石学、地球化学研究表明：喀左盆地3个油页岩层群分别发育于下白垩统九佛堂组的一、二、三段，以位于三段的第三油页岩层群的工业意义最大；油页岩常与上覆沉凝灰岩或其它凝灰质岩石呈伴生关系。

Unground natural calcium phosphates, natural aluminium calcium phosphates and phosphatic chalk, excl.

The intrusion ages range from 183.1 Ma to 99.5 Ma(except one of 715.6 Ma), most of them about 150 Ma with isochron age of 132.1 Ma, placing them in early Jurassic to Cretaceous in age.

40Ar/~(36)Ar—40K/~(36)Ar等时线图解给出的等时年龄为132.1Ma，说明这些花岗岩在形成时代上属中侏罗到早白垩世。

As the northern boundary of the North Dabie complex unit, the motion of the Xiaotian-Mozitan fault in the Early Cretaceous can be used to understand evolution of the North Dabie complex unit during doming.

晓天－磨子潭断裂是北大别杂岩带的北部边界，其早白垩世构造活动型式可以为北大别带穹隆演化过程提供制约。

If the tectonic uplift is not considered, the relief of Dabie orogen will reach at least 3km in Late-Cretaceous. As to the value of the relief reduction factor in Dabie orogen at 90Ma, the largest value appeared in northeast region, followed consecutively by the core and southeast Tanlu fault zone, with the smalleast value appeared in northwest and southwest region. The results reflect the strong uplift difference between core and North Huaiyang flank in Dabie orogen during doming extension period. Relief in the core region and southeast Tanlu fault zone is higher than those in the peripheral regions, northwest and southwest flanks are more stable than other regions.

如果不考虑构造抬升，大别造山带在晚白垩世地形起伏至少可达3km.90Ma时大别造山带地形起伏变化率在空间上呈现如下特征：东北区块最大，热窿核部其次，东南郯庐断裂区块再次，西北、西南区块最小，反映大别造山带热窿伸展期，核部与北淮阳翼之间强烈差异隆升，核部地形和东南郯庐断裂区块起伏高于周边地区，西北、西南两个翼部比其他地区稳定。

And, as anyone who has studied chemistry at schoolknows, if youdrop chalk into acid it fizzes away to nothing.

并且，在学校做过化学实验的人都知道，如果你把白垩丢进酸性溶液里，它会嘶嘶作响直至溶解殆尽。

But the miniplate became even softer,still opaque and easy to break with some gabs on the surface six months later.The miniplate became into something like cheese,softer and exquisite twelve months later.

扫描电镜观察可见散在的比较表浅的小裂纹和凹槽；植入后6个月时，大体观察见接骨板表面已经变成白垩色，质硬，不透明，易折断，其上有裂纹。

Chalk or limestone soils, such as marls.

例如在白垩、或泥灰这种富含石灰石的土壤中生存的植物。

Here at the base of the chalk formation he neared the brood that oozed from it.

就在那个白垩质山岗的山根下面，他走近了那条由山根下涌出来的小河流。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
