Then we searched through the transition metals to see if we could do better than osmium, to get an expansion of less than 10 percent.

凯恩说：于是我们仔细搜索了所有过渡金属以确认是否有比锇更好的过渡金属，从而使膨胀系数少于10%。

"We found that if we combine boron with osmium, we push the osmium atoms apart by only 10 percent from where they were in osmium metal, which is very good; you want to push them apart as little as possible," Kaner said.

我们发现，如果我们把硼和锇结合在一起，我们只能使锇金属中锇原子的分隔距离扩大10%，这已经非常不错了；如果你想尽可能地缩小原子之间的分隔距离，就需要寻找更好的过渡金属。

The acidic composition can be prepared by mixing a monovalent or polyvalent cation and an organic acid in the presence of a strong oxyacid, wherein the resultant acidic composition is less corrosive to a ferrous metal than a solution of a mineral acid having the same acidic pH value as that of the acidic composition, and where in the acid composition is more biocidal than a mixture of the organic acid and a metal salt of the organic acid which mixture has the same acid normality value as that of the acidic composition.

所述酸性组合物可以在一种强羟基酸存在时，通过混合单价或多价阳离子和有机酸来制备，其中与具有相同的酸性pH值的无机酸溶液相比，所形成的酸性组合物对含铁金属的腐蚀性更小，并且与具有相同酸当量值的有机酸与有机酸金属盐的混合物相比，所述的酸组合物具有更强的杀生物作用。

In the concentration of 0~1 mol?L^(-1), the chemical shift of 17O-NMR δ(H2^17O in aqueous solutions of alkali chloride, alkaline earth chloride, sodium halide or some common oxysalt were measured.

在小於1mol？L^(-1)的浓度范围內，测试了硷金属、硷土金属氯化物、卤化钠及其它常见含氧酸盐溶液的17O-NMR化学位移δ

Results The percentage of produced metallo-β-lactamase, lossed outer membrane OprinD2 and active efflux system in P A resistance to carbapenem are 29.8%, 31.9% and 31.9%, produced other β-lactamase is 6.4%, Conclusion Metallo-β-lactamase production is one of the main mechanisms in PA resistance to carbapinem, the result of correct detection in laboratory can not only promote the rational application of antimicrobial agents but also prevent the spread of bacterial resistance

结果 产金属酶、D2缺失、外排泵出分别占29.8%、31.9%、31.9%，产其他β-内酰胺酶占6.4%。结论产金属酶是PA耐碳青酶烯类抗菌药物最主要机制之一，准确的实验室检测不仅可以帮助临床合理选用抗菌药物并可减少细菌耐药性的传播。

Historical research has been carried out to rediscover lost metals of the highest standard and finest finish, from 958 Britannia silver to paktong, a re-discovered metal derived from an 18th-century Chinese candlestick, to Tula steel not used in furniture since the reign of Catherine the Great.

历史的研究已经进行了重新找回失去金属的最高标准，最好的成绩，来自958不列颠白银paktong ，重新发现的金属源于18世纪的中国烛台，以图拉钢没有用的家具，因为统治叶卡捷琳娜大帝。

Zinc was recognized in Europe as a separate metal in the 16th century when Agricola (1490 – 1555) observed that a metal called "zincum" was produced in Slesia and Paracelsus (1493 – 1541) stated clearly that "zincum" was a new metal.

锌作为一种单独的金属在欧洲被认知是始於16 世纪，当阿格里科拉Agricola (1490-1555)观察到一种叫作"zincum"的金属在Slesia生产的时候

There is a dielectric film between the two parallel-plate of the tunable capacitor. The dielectric film severs to prevent contact between them.

这种结构包括两层可动金属板，下层金属板上覆盖一层薄的绝缘层，防止两层金属膜发生接触粘连。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
