The ordering parameters of GaInP are deduced from the polarization dependence {E||[110] and E||[1 0]} of the PR signals from the emitter regions. The ordering related piezoelectric fields are found to influence the electric field, as evaluated from the observed Franz-Keldysh oscillations, in the GaInP region. According to the experimental data of the as-grown GaInP/GaAs/GaAs samples, we find that for the same emitter doping level the emitter field in the more ordered materials is smaller than in the less ordered sample.

经由分析A系列样品的FKOs信号，估算出射极/基极区域的内建电场，加上极化实验的结果，可以估计磷化铟镓的有序程度；因为压电场的关系，发现当GaInP能隙越小时，内建电场也会跟著降低；温度变化实验，验证其内建电场会随著温度增加而变大，只是变化量不甚明显；利用Varshni及Bose-Einstein方程式来估计一些与温度相关的参数值，并与相关文献比较，其结果颇为相符。

Based on limiting the tensile strain at the bottom of the asphalt layer and the vertical compressive strain at the top of the subgrade, the suitability of layer thickness is checked by two criteria. One is controlling the maximum surface deflection under the design load, and the other is controlling the modulus ratio between adjacent unbound aggregate base and subbase layer.

该方法基于限制沥青层底的拉应变和路基顶面的压应变，采用两个准则来校核所设计的沥青层厚度的适宜性：一是控制设计荷载作用下的最大路表弯沉；二是控制相邻两个无结合料处治的集料层的模量比。

In the POPF model, wind farm is modeled by the probabilistic wind farm model considering the reactive power-slip characteristic, and the inequality constraints include not only the unit output constraints, the ratio constraints, the voltage constraints and the line current constraints but also the reactive compensation capacity constraints in wind farm and the system climbing capacity constraints per minute. By introducing the NCP function, the KKT conditions of POPF system are transformed equivalently. Based on the transformed nonsmooth nonlinear algebraic equations, the FOSMM is used to determine the POPF model expressed by the numerical characteristic of variables. The model includes nonsmooth functions, so it can be solved by a semismooth Newton-type method based on the subdifferential.

概率最优潮流模型中，风电场采用考虑无功功率—滑加热器差特性的风电概率模型，不等式约束中除了机组出力约束、有载调压变压器变比约束、电压约束和支路电流约束，也考虑了风电场无功补偿容量约束、系统的分钟级爬坡能力约束；使用非线性互补函数将概率最优潮流的KKT条件转化为一组包含有不光滑函数的非线性代数方程组，然后基于一次二阶矩法确定了以待求量的数字特征表示的POPF模型，由于该模型包含不光滑函数，因此采用基于次微分的半光滑牛顿型方加热器法求解。

The deformation of conductive particles in pure metal connected by anisotropically conductive adhesives has been investigated using finite element analysis. The results indicate that the increment in stresses of the conductive particles begins at the contact area toward the boundary through the centers of conductive particles when the reduction in height increases. When stress is over the yield strength, the similar behavior was observed. So the deformation of conductive particles is not uniform, which means that the deformation of conductive particles is the same as the stress does.

采用有限元模拟分析了各向异性导电胶连接的纯金属导电颗粒的变形过程，研究结果表明，随着压下量的增加，导电颗粒的应力增加由接触面开始，经中心区域向导电颗粒的周边扩展，大于屈服强度的应力变化与此相似，因此导电颗粒的变形是不均匀的，即导电颗粒的变形由接触面开始，经中心区域向周边区域进行。

Exhibiting angle unconformities or erosion unconformities in different part of the basin, these surfaces are obvious to be recognized on seismic profiles.T1 conformity, separating Eogene from Neogene, was formed during the whole basin uplifting and erosion by the end of Eogene.T1 unconformity denuded unbearing strata differently, and the deeper and thickest erosion lies on the southern margin of the basin, which reflects the activity of southern Jiangnan paleo-terrene. In conclusion, the major erosion belts extending along NW direction reflects NE-SW compression and slipping caused the Eogene basin uplift and strengthen the earlier NW direction extending low convex, and formed the NW direction extending depress and erosion belts.

When the timing is off, you can get collapses on the upper wingtip as well as the lower one. I've seen cravatted wings spiraling down after doing off-timed wing-overs, so be careful and build up your wing-over height gradually. First, get the timing right in small wing-overs. When you feel confident, use more weight shift and brake input to build up your wing-overs. Keep practicing!

如果时机掌握的不好，伞可的两侧都有可能塌陷；我曾经见过由摆荡动作时机掌握的不好导致卷夹然后螺旋下坠的，所以摆荡的幅度要逐渐增加；首先要在小幅度摆荡中将各个动作的时机掌握好，练习熟练，信心增强之后在多压重心，增加刹车量将摆荡的幅度作大。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
