三次

With the international flows of factors, such as commodities, capital and labor force...etc., China economy depends on the world economy closer and closer and the problem of exterior equilibrium and internal equilibrium have emerged.

而 1994 年以来，货币政策和汇率政策出现了三次明显的冲突，这三次冲突的实质是独立货币政策(基础货币投放适度、人民币利率水平可控)和汇率政策的关系问题。

In the first part of the paper, we construct a family of 1 parameter cubic algebraic curves interpolating four given points and two tangent lines at the endpoints, and one can manipulate the shape of cubic algebraic curves by controlling the points or the tangent line directly.

该文提出的代数曲线的结构有两种，一种是插值平面上四点及两端点切线的三次代数曲线；另一种是插值两端点、两切线及两曲率的三次代数曲线。

In the last part of the paper, we construct a family of 2 parameter cubic algebraic curves interpolating two given endpoints and two given tangent lines and two given curvatures at these two endpoints with different initial cases in detail.

引 言三次参数曲线在计算机辅助几何设计与计算机图形学领域一直扮演着十分重要的角色，这主要是由于三次参数曲线是具有奇异性的次数最低的曲线，这些奇异性包括尖点、拐点和闭圈。

This is its third long-distance missile test; all flops.

这是朝鲜第三次远程导弹测试，三次都失败了。

Hideo Hashimoto came close with a strike from outside the area eight minutes after the hour mark before Gamba came close to snatching all three points in stoppage time but Zeng produced three close range reaction saves in quick succession to deny Lucas and substitute striker Ze Carlos.

Hideo Hashimoto在68分钟的时候得到了一次绝好的得分良机，刚把队也在伤停补时阶段连续获得全取三分的机会，但是曾诚连续的三次快速反应使得卢卡斯和替补前锋卡洛斯都无功而返

After graduating from karts, Hamilton made his mark in Formula Renault, finishing the 2002 British season in third place overall and taking three podium finishes from four starts in the EuroCup series the same year.

从卡丁赛事中毕业以后，汉密尔顿开始参加雷诺方程式的比赛，并在2002英国赛季中获得了总成绩的第三名，并在同一年的欧洲杯系列赛中四次参赛就三次登上了领奖台。

The curve of third harmonic sound pressure level(SPL3)is alsoa "periodic function".The period length is about"first resonancefrequency" of the tube Δf=f0=c0/(2L).The magnitude of SPL3 canbe predicted by Coppens theory(with one of the parameters modified).

三次谐波声压级变化曲线为一"准周期"函数，周期长度为驻波管的第一共振频率值Δf＝f0＝C0/2L，用Coppens所推导的"共振"时公式，计算三次谐波共振峰的量值，表明仍存在差异，只有经过参数修正才能所得结果。

For Hernandez, it was his third consecutive loss and it marked the second time in his last three starts that he has allowed six or more runs.

这是Hernandez今年第三次输的这麼难看。数据上显示，这是他最近的三场比赛，第二次被得了六分以上。

Ythagorean hodograph curves enjoy a number of remarkable properties, such as, its offset curves have exact rational representations; the arc length function of a Pythagorean hodograph curve is simply a polynomial function of the curve parameter; and the lower degree Pythagorean hodograph curves have intuitive geometrical interpretation.

H曲线具有诸如有精确的有理 Offset、弧长函数可由多项式函数表示以及几何解释优美等一系列优良性质。基于复分析方法，避免了实分析讨论中出现的复杂表示及繁琐计算，构造了满足给定 C1 Hermite插值条件且以C1拼接连续的三次 PH曲线偶。该曲线偶可灵活处理拐点，从而克服了一般三次 PH曲线因恒凸而无法处理拐点的缺陷。

Then they ran a third trial, this time with volunteers who ate normal kiwi fruit .

于是他们又进行了第三次试验，第三次试验是让志愿者使用普通的猕猴桃。

Do you know, i need you to come back

你知道吗，我需要你回来
