Thus the sample size can be increased, and the nugget effect and detection limits can be decreased compared with normal Carius tube technique. This new technique is capable of digesting 12 g samples in a 75 mL Carius tube with 35 mL aqua regia at 320℃, and Re and all the PGEs can be measured.

由此可以加大取样量，降低铂族元素测定过程中的块金效应及检出限，使超低含量铂族元素的测定成为可能。12g样品在75mL卡洛斯管中用35mL王水于320℃溶解15h，基本上可以使各种地质样品中的铂族元素矿物完全溶解。

The invention provides a fuel cell carbon platinum-carried compound catalyst with small amount of platinum and high catalytic activity, and a preparation method thereof.

本发明提供了一种铂用量少且具高催化活性的燃料电池碳载铂复合催化剂及其制备方法。

objective:to study the effect of tuting oral liquid on treating cisplatin-induced pigeon'vomiting.methods:the animal model was designed by injecting the chemical medicine cisplatin in pigeon's abdomen, vomiting reaction was observed by the vomiting times and delitescence.

目的：观察吐停口服液对顺铂所致家鸽呕吐的作用。方法：采用家鸽腹腔注射顺铂法制造呕吐模型，观察家鸽呕吐次数、呕吐潜伏期。

Nonplatinum cytotoxic doublets are acceptable for patients with contraindications to platinum therapy.

对于铂类药物有使用禁忌的患者则推荐使用两种非铂类细胞毒性药物联合方案。

Meanwhile, heating power of the rear face heater was also one of the main factors that affected bubbles incipience and diameters.

结果表明，微通道内不稳定性流动沸腾的振动流态，是铂膜上形成各种泡并以不同方式脱离铂膜的原因；背面加热膜的功率大小也是影响铂膜长泡以及汽泡大小的主要因素之一。

According to the mineralization of Cu-Ni and Pt-Pd deposit, Cu-Ni sulphides were formed by liquation in the late phase of fractional crystallization of magma chamber, and the Pt-Pd mineralization mainly occurred on the process of fluid action after diagenetic stage.

就铜镍和铂钯矿化而言，铜镍硫化物形成于岩浆房分离结晶晚期的熔离作用，而铂钯矿化则主要在成岩期后流体作用阶段形成。

In the coming days, Pullman will step up its pace to pass high quality to more people.

三亚亚龙湾铂尔曼度假酒店为铂尔曼全面登陆亚洲酒店市场拉开了序幕，在接下来的日子里，铂尔曼会加紧步伐，将自己的高品质传递给更多的人。

On the basis of ascertaining that phosphomolybdic acid modified platinum electrode has higher catalytic activity to methanol oxidation , three kinds of transition metal substituted phosphomolybdic acids were synthesized, and the IR spectrum indicated that the compounds still kept Keggin structure.

在证实了磷钼酸修饰铂电极对甲醇氧化具有较高活性的基础上，合成了3种过渡金属取代的磷钼酸，通过红外光谱测试仍为Keggin结构，并制备了过渡金属取代磷钼酸修饰铂电极，研究了修饰铂电极在硫酸溶液中的电化学行为及对甲醇的催化氧化作用。

Also the performance of this modified electrode was compared with sodium molybdate modified platinum electrode. The cyclic voltammetry tests show that phosphomolybdic acid modified platinum electrode can increase the catalytic activity for methanol oxidation and it is almost the same as the mono-molybdate (Na2MoO4) modified Pt electrode does. This promote effect mainly comes from the transformation of different valency of molybdenum.

通过循环伏安和计时电流法研究了该修饰电极对甲醇氧化的电催化活性和抗中间产物的毒化作用，并比较了该修饰电极与其单酸盐(Na2MoO4)修饰铂电极的性能，测试结果表明：磷钼酸修饰铂电极能够提高对甲醇氧化反应的催化活性，基本上同其单酸盐Na2MoO4修饰铂电极的催化活性相当，并且这种促进作用主要是由Mo原子价态变化引起的。

PGE analyses for the picrites of the middle Devonian Beitashan Formation at the south margin of Altai Mountains show that the PGE concentrations are within a narrow range, and their primitive mantle normalized PGE patterns resemble those from Grenada picrites, Lesser Antilles Arc in Atlantic, which is characterized by the enrichment of PPGE although the PGE contents of the researched picrites are higher than the latter, and lower than those from large igneous provinces.

本研究对新疆阿尔泰山南缘中泥盆世北塔山组地层中的苦橄岩的铂族元素进行了分析，结果表明：其铂族元素的含量总体变化不大，其原始地幔标准化曲线总体上和已经报道的大西洋Lesser Antilles岛弧的Grenada苦橄岩相似，均以富集把组铂族元素为特征，但总体含量比后者高，而比大火成岩省的苦橄岩低。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.

万寿菊对土壤要求不严，以肥沃。排水良好的砂质壤土为好。

He unstepped the mast and furled the sail and tied it.
