拐点

As for the inadequate contrast of infrared thermal imaging, as S curve mapping function is proposed to enhance target objectives and in the meantime suppress background clutters, which has the same range of domain with a variable interval and a non-symmetrical inflection point.

针对红外热成像对比度不足的问题，提出了一种S曲线映射函数，该函数具有定义域与值域区间一致、拐点非对称的特点，在目标图像增强的同时拟制了杂波背景。

Hence the following conclusion can be made:①Although an inflection point occrus on the cooling curve, it cannot be regarded as secondary recalescence, but might be called as pseudo-recalescence.

据此认为：①实验中所获得的冷却曲线，尽管再辉阶段出现温度变化拐点，但不能认为是"二次再辉"，姑且称作"伪再辉"。

And the ideal segmenting threshold should be at the point of the critical point between the peak and tails.

此算法以图像的累积直方图拐点为分割阈值，不受目标区面积大小的影响。

Semilethal temperature was determined by using Logistic equation fitting for inflection point value.

并用Logistic方程拟合求拐点值来估计其半致死温度，探讨其抗寒性。

This thesis,starting from working out the arrest points and the infl ection points of the function curves of the grey mathema tical model GM(1:1 )and its residual correction model and residual period model, derives the conditions for empliying these grey models to obtain a higher class of accuracy,thus enabling the user to decide which model should be used in the light of the state of given initial sequency data.

从求得灰色数学模型GM(1.1)及其残差指数修正模型和残差周期修正模型函数曲线的驻点与拐点入手，导出使用这些灰色模型取得较高精度的条件，让使用者可依据初始序列数据的态势决定采用哪种数学模型，并且在结果未揭示以前便可大体上估计到拟合精度是否令人满意。

However, with today's financial crunch is steep and high pressure to launch a series of land policy and now these "heretical" has been closed almost all of .8 31, all land must be linked into the trick shot; national moratorium on the approval of agricultural land to six months non-agricultural construction land; development zone approved by the investigation and stopped; not paid land transfer payments not only permit but even the land can not get pre-sale licenses are never expect; banks to stop lending or even the second set of residential land and house mortgage loans have been suspended …… it seems the real estate industry in China overnight back in 1993 to "liberate" before the macro-control period, what inflection point theory, and even the collapse of the winter will have on the spondee!

然而，今天的金融危机是陡峭的高压推出了一系列的土地政策，目前这些"邪教"已关闭几乎所有的0.8月31日，所有土地必须联系到把戏杆；国家暂停核准农业用地6个月非农业建设用地；开发区批准的调查和制止；没有支付土地出让金不仅允许，甚至土地不能获得预售许可证从未期望；银行停止贷款，甚至是第二套住宅用地和住房抵押贷款已经暂停……看来，房地产行业在中国一夜之间回到1993年的"解放"前的宏观调控时期，什么拐点理论，甚至崩溃的冬天将会对扬扬格！

August 31, all land must be linked into the trick shot; national moratorium for six months for approval of agricultural land to non-agricultural construction land; development zone approved by the investigation and stopped; not paid land transfer payments not only permit but even get pre-sale of land Permits are never expect; banks to stop lending or even the second set of residential land and house mortgage loans have been suspended …… it seems the real estate industry in China overnight back in 1993 to "liberate" before the macro-control period, what inflection point theory, and even the collapse of the winter will have on the spondee!

8月31日，所有土地必须联系到把戏杆；全国暂停半年审批农用土地向非农业建设用地；开发区批准的调查和制止；没有支付土地出让金不仅获得许可证但即使预售许可证的土地从来没有期望；银行停止贷款甚至第二套住宅用地和住房抵押贷款已经暂停……看来，房地产行业在中国一夜之间回到1993年的"解放"前的宏观调控时期，什么拐点理论，甚至崩溃的冬天将会对扬扬格！

Using Taylor Theorem,we generalize the second sufficient conditions for extreme point and inflection point,and give the classification for a large class of stationary point .

利用泰勒定理，推广了极值的第二充分条件和拐点的第二充分条件，并对某一大类驻点进行了分类。

This study has been interpreted to support the importance of ventilating at airway pressures below the upper inflection point.

该项研究被解读为支持了这样一种观点，即在气道之上拐点以下呼吸的重要性。

Results indicate: after compelling exposal, with the increase of low lighting level, the three reaction time curves have a same decline tendency, and there is an effective inflexion at 50 lx lighting level.

结果表明：在三种曝光强度下，随着视标照度水平的提高，受试者判别反应时曲线都呈先急后缓的下降趋势，并在视标照度为50 lx时出现一有效拐点。
