斜率

The dependence between the flexural strength and the size of Chinese fir dimension lumber was investigated.206 dimension lumbers were sorted into three test groups in terms of dynamical modulus of elasticity.

选取206根人工林杉木规格材，按照动态弹性模量配成3个测试组，研究了规格材测试跨度与其抗弯强度之间的依存性，并利用斜率法和形状参数法求得抗弯强度5%分位值和50%分位值的长度尺寸效应。

This paper establishes cubic spline function, analyzes subsection curve function and curve slope and curvature, at last decides to place the curve especial points which can be obtain easement curve length and other line parameters, such as the ZH point (end of line and beginning of transition curve), the HY point (end of transition curve and beginning of circular curve), the QZ point, the YH point (end of circular curve and beginning of transition curve), the HZ point (end of transition curve and beginning of line).

针对公路平面线形的8种组合类型，其线形元素特征则由最基本的直线、圆曲线、缓和曲线组成的特点，解析三次样条函数模型，得分段曲线函数、曲线斜率、曲率，从而确定曲线特征点（直缓ZH点、缓圆HY点、曲中QZ点、圆缓YH点、缓直HZ点）位置，进而得到曲线缓和曲线长度及其他线形参数。

When gas pressure is constant, delay decreases with the increase of laser energy and percent of self-breakdown voltage.

当激光能量一定时，延迟时间随充气压力的减小和电压的增加而减小，并且不同充气压力的延迟时间随电压变化的曲线斜率是随电压的增加而减小的。

Result: In first experiment, the results shows erector spinae of CLBP had positive correlation in the force-sEMG signal relationship on the testing of non-fatigue state of step extensions exercise; AEMG, MPF, IMPF increased with the load, but the Lempel-Ziv Complexity remain firm against the load. The second experiment of the research was that the mean values and the slopes of sEMG of the LBP were significantly different from healthy subjects during the isometric contractions of 20%MVC load intensity, except AEMG.

90秒静态负荷运动过程中，10％MVC运动强度时，慢性下背痛被试和健康被试AEMG、MPF、IMPF、复杂度的均值均没有显著性差异；20％MVC运动强度时，健康被试的MPF、IMPF、复杂度均值都低于LBP被试，对于10％MVC和20％MVC运动负荷强度时，慢性下背痛被试的AEMG、MPF、IMPF、和C的变化斜率都快于健康被试，除AEMG外，其余指标的变化率之间均有显著性差异；在两种负荷强度下的静态运动负荷实验中，左右侧腰部竖脊肌肌电信号特征无明显差别。

By calculating the neutron skin thickness of nuclei in the range of Z = 8 ~ 120, A = 5Z/3 ~ 3Z ,we find a linear relation between the neutron skin thickness and the isospin asymmetry degree δ:, which is in agreement with the result extracted from the measurements by antiproton annihilation method i.e.:.

我们发现中子皮厚度随对称能系数 a s 以及对称能在饱和密度附近的斜率L、曲率Ksym的增大呈现近似的线性增大的趋势，对称能越硬的核势确定的中子皮越厚。

Using the data from antiproton annihilation method, we get the ranges of the slope , curvature of the symmetry energy near the saturated densityand the symmetry energy coefficient as : L = 20 ~ 100MeV,Ksym =-256 ~ 70MeV, as = 30 ~ 35MeV.

以反质子湮灭法拟合的参考实验值作为标准，我们给出对称能系数，对称能在饱和密度附近的斜率和曲率的参考范围分别为：as = 30 ~ 35MeV ，L = 20 ~ 100MeV，Ksym =-256 ~ 70MeV。

However, for the delay model, there is a "hump" while the slopes to two asymptotes remain the same.

然而对於时间延滞模式，虽然两渐进线斜率不变，但中间有个突起。

Assessment of Gastric Sensitivity, Compliance and Accommodation: The stomachs were distended isobarically by barostat via a double-lumen polyvinyl tube with an adherent plastic bag, gastric sensitivity was measured by perception threshold and gastric compliance was calculated as the slop of the pressure-volume curve.

胃敏感性、顺应性和容受性的检测：用barostat及双腔气囊导管对胃进行等压扩张，以患者的不适阈代表胃对扩张的敏感性，以压力-容量曲线的斜率反映胃顺应性；将气囊压力恒定为MDP+2mmHg，以进食前后胃内平均容量的差值来反映近端胃的容受性。7。

Considering higher rate of buid-up, we used a different method unlike the common continuos beam theory and three bending moment equations.

考虑到井眼有较大的造斜率，本文采用了与一般连续梁理论及三弯矩方程不同的方法。
