Because of special geometry structure of three-cone bit, the top of formation will form a tri-spine well bottom while drilling with three-cone bit the drill string. It is the tri-spine well bottom that leads to the axial harmonic of vibration when the bit revolves a round and the three concavo-convex heave of bit and formation result in one time (1×rpm),two time (2×rpm), three time (3×rpm) turning table speed.

高岩由于三牙轮钻头的特殊几何结构，钻进过程中在岩层顶部容易形成一个三脊状井底，正是这一三脊状井底，当钻头旋转一周时钻柱轴向三次凸凹变化，由此在轴向产生1倍、2倍和3倍及其更高次倍于转盘转速rpm的谐波振动。

From 2001 to 2005, spending on Internet content nearly tripled, according to the Online Publishers Assn.

在线出版协会说，从2001年到2005年，网络内容的消费支出将近翻了三倍。

In North Waziristan, for example, a 2006 agreement led to a tripling of cross-border infiltration.

达成 过。例如在北瓦齐里斯坦，2006年的一个协议导致了三倍的跨边界的

In November 1918, Marshal Foch had commanded three times more than Eisenhower did in November 1944, on a front of approximately the same length.

战线长度几乎相当的情况下，1918年11月福煦元帅指挥的人马三倍于1944年11月艾森豪威尔所指挥。

But that was enough to buy the gold in Fort Knox three times over, if America upheld its commitment to sell the metal at $35 an ounce. Britain's request to exchange dollars for gold on August 13th 1971 was the last straw.

但是，如果美国履行他的承诺以35美元一盎司的价格出售黄金的话，那些钱足以购买三倍的福特诺克斯堡的黄金。1971年8月13号英国要求用美元兑换黄金的请求是压倒骆驼的最后一根稻草。

The furthest along in development are the glucagon-like peptide-1 (GLP-1) drugs, which pack a triple whammy against the disease, stimulating insulin secretion, suppressing glucagon secretion, and inhibiting gastric emptying. The furthest along in its class is exenatide, a synthetic version of a GLP-1-like substance found in the saliva of the Gila monster. An open-label study reported at the meeting showed that about half of patients failing oral therapy achieved near-normal glycemic control when exenatide was added to their regimen.

最先进的研究是类高血糖因子胜-1（GLP-1）药物，这种药物对於疾病的药效高出三倍，可以刺激胰岛素分泌、抑制高血糖因子分泌和抑制胃清空，其中最先进的一类药物为exenatide，这是一种从希拉毒蜥的唾液所合成的类GLP-1物质，根据一项公开标示的研究显示，无法以口服治疗的患者中，有一半的患者在服用exenatide之后，其血糖接近正常值。

His study of Manchukuo, which had a population of 40 million and was three times the area of Japan, catalyzes a broader understanding of new global trends that characterized much of the twentieth century.

杜赞奇对拥有四千万的人口、面积为日本三倍的满洲国的研究，对於颇能描述二十世纪之特色的新全球趋势，激发出更宽阔的认识。

Ppmv, some three times lower than the California South Coast Air Quality Management District requirement.

浓度为5000 ppmv。出口SO2浓度低于15ppmv，较&加利福尼亚南部沿海空气质量管制区&要求低三倍左右。

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