拐点

Flex point of the curve.

曲线的拐点。

The relationship between the apparent viscosity and temperature can be expressed by Arrhenius Equation. But there is a flex point during heating, and the viscous flow activation energy at the low temperature is greater than that at the high temperature.

液化残渣的黏度－温度关系符合Arrhenius关系式，但在升温过程中出现了拐点，低温段的黏流活化能比高温段的要大。

Just because the difference quality of the two has determined the necessity studying too;OP has flex point which can be used to judge AT in the course of sport ,and research proves that the means is more accurate;Research proves that no positive pertinency is between OP and HR,but the author believe it only accounts for lack of the quizzees;The better the enginery of human is,the higher the positive pertinency among VO2、OP and HR is.

也正因为二者的差异性决定了研究的必要性；氧脉搏在运动过程中存在拐点，可以判断无氧阈。

According to the migration law of each sintering zone, the temperature at the flexions can be obtained, which represents that the forefront of each sintering zone arrive at the sintering grate.

结合烧结过程各带的迁移情况，计算得出拐点所对应的各带前沿到达料层底部的温度。

The temperature curve of flue gas was fitted by the least square methods during the sintering process, and then 4 flexions of the temperature curve were calculated by solving a two-order derivative of the temperature curve.

提出利用最小二乘法拟合烧结废气温度曲线，求曲线方程的二阶导数计算出烧结废气温度的四个拐点。

Under the condition that the flux function has one inflection point, by the structure of weak entropy solution of the corresponding initial value problem and the boundary entropy condition developed by Bardos-Leroux-Nedelec, we give a construction method for the global weak entropy solution of the initial-boundary value problem arid clarify the solution structure nearby the boundary.

在流函数具有一个拐点的条件下，由相应的初始值问题弱熵解的结构和Bardos-Leroux-Nedelec提出的边界熵条件，给出初边值问题整体弱熵解的一个构造方法，澄清弱熵解在边界附近的结构。

A cusp catastrophe model is presented to describe the behavior of sliding along one deep incompetent structural plane of a gravity dam foundation, and the sufficient conditions leading to instability are discussed. It is found that the instability of sliding relies mainly on the stiffness ratio k, the homogeneity index of the medium m and the geometry-mechanic parameter ξ and that the reliability of the traditional limit analysis method is deficient.

通过建立的模型分析，发现坝基滑动失稳主要取决于软弱面上复杂弹脆性介质和应变软化介质在应变软化拐点处的刚度比k、材料的均匀性指标m及几何－力学参数ξ；并给出了发生突变失稳的充分力学判据，指出传统的刚体极限平衡分析法存在一定的缺陷。

The results showed that the respiration rate of J1Jm (Japan♀×Japan♂) and C1Jm (China♀×Japan♂) increased with increase in water temperature, but significantly decreased at over 18℃. The respiration rate in "Chinese red" and its half-sib families (C1Rh, J7Rh, RjRh) sharply decreased at 21℃, indicating that the "Chinese red" and its half-sib families adopted higher temperature. The changes in NH4-N excretion rate showed a similar tendency to the respiration during the experiment.

结果表明：J1Jm（皱纹盘鲍日本群体♀×日本群体♂）和C1Jm（皱纹盘鲍中国群体♀×日本群体♂）的耗氧率随水温的升高而上升，但超过18℃在21℃下耗氧率明显下降，RwRh与其半同胞家系(C1Rh、J7Rh、RjRh)的耗氧率拐点出现在21℃，说明&中国红&及其半同胞家系更适宜较高温度；各家系排氨率随温度升高的变化趋势与耗氧率基本相同。

The main elements are: core, limb, inflexion point, inter-limb angle, turn, hinge, crest line, trough line and axial surface.

褶皱要素是褶皱的基本组成部分，褶皱要素主要有：核、翼、拐点、翼间角、转折端、枢纽、脊线和槽线、轴面

Britain was ill-placed because it was running a sizeable deficit at what turned out to be the peak of the economic cycle.

原译：但英国已将自己置于了不利境地，因为在经济处于拐点的时刻英国的财政赤字依然相当庞大

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
