变化点

Baidu is to participate in search result artificially, and concern price of key word contest serve, so the first page is to basically be done not have, the money that who makes is much, who discharges the first page, whose click charge to go out more every time, who most, so Chinese crystal net basically is a platoon in the first page or coping of the 2nd page, the rank is between 8-20, change is not big, popularize a business as each that day unexpectedly of price cost gone, arrived in the evening, basically discharge in 8-10 of the first page

百度是人工参与搜索结果，并且有关键字竞价服务，所以第一页是基本上没有了，谁交的钱多，谁就排第一页，谁的每次点击费用出得多，谁就最一位，所以中国水晶网基本上是排在第一页或第二页顶部，排名在8-20之间，变化不大，随着各推广企业当日竟价费用的用完，到了晚上，基本上排在第一页8-10位

本文对大连夏季室外凉亭下的环境特征和人的热舒适性做了主观问卷调查研究，通过对428个有效样本的研究与分析，回归得到了人体热舒适投票值TCV与人体平均温度和周围空气温度之间的关系式，在满足该式的条件下，人体平均温度在35.7~36.5℃之间，空气温度在25.5~30.4℃之间变化，且空气相对湿度保持在40%~60%，风速在0~1.5m/s之间波动，人体都可以达到热舒适状态，并发现人们在室外自然环境下往往感觉吹风不足，这点正好与传统空调中人们易产生吹风感的抱怨相反，从而为适当提高送风速度与温度，节约空调能耗奠定了基础。

In laboratory testing, coupons were immersed in brine continuously and intermittently to simulate the corrosion of the high strength steel wire in concrete crossbeam of bridge, the parameters about corrosion details of concrete coupons at different times were monitored by electrochemical impedance spectroscopy.

在实验室内进行钢丝全浸和对水泥试样间浸试验，利用电化学阻抗谱监测水泥试样中钢丝的腐蚀参数变化，并用极化曲线初步评定了阻锈剂对钢丝点蚀的影响作用；在大桥现场，用电化学方法快速检测了钢丝的瞬时腐蚀电流。

With the increase of vibration frequency, the variation process of Jacobi matrix eigenvalue was calculated. According to the position of eigenvalue crossing the unit circle in the complex plane, the stability of fixed point of the map was discussed and the route from periodic motion to chaos via period-doubling bifurcation was received.

以振动频率为控制参数，计算得到映射Jacobi矩阵特征值的变化曲线，根据其穿越复平面单位圆的位置，分析了映射不动点的稳定性，获得了碰撞运动通过典型的倍周期分岔通向混沌的过程。

The results showed that net photosynthetic rate P(subscript n, transpiration rate T(subscript r, stomatal conductance G(subscript s, intracellular concentration of CO2 C(subscript i, water use efficiency of cultivars and the light saturation point in leaves of 5 cultivars were different and had obvious differences, and the light compensation point was similar. Diurnal change of net photosynthetic rate among cultivars were different, three cultivars showed twin-peaked curve with an obvious midday-depress, others showed single peak curves.

结果表明：不同品种的净光合速率P(下标 n、蒸腾速率T(下标 r、气孔导度G(下标 s、胞间CO2浓度C(下标 i、水分利用率和光饱和点之间的差异明显，各品种的光补偿点均较低；净光合速率的日变化也存在明显的品种间差异，有3个品种呈&中午降低型&的双峰曲线，2个品种呈单峰曲线。

For example,"the principle and application of multi-balance heat change" is about saving energy;"Questioning about the function of swimming bladder" is about biology;"the research of the formation thunder and the method of lightning energy" is about meteorology;"several hypothesis of the formation and change about the earth magnetic phenomenon" is about astronomy.

Formulas of magnetic field with surface current density and that with point current density are presented.

给出了面电流分布下2维磁场的计算公式，较点电流分布下的磁场公式更能细致准确地反映出磁场的变化。

Methods: 90 Sprague-Dawley rats were randomly divided into 3 groups: control group, emotional stress group and footshock group.

90只SD大鼠，随机分为3组：空白对照组、足部电击组和情绪应激组，采用反转录－聚合酶链作用技术，检测应激后不同时间点三叉神经节中CGRP mRNA水平的变化。

With the change point theory, we analyzed the change of the stock market, and draw some meaningful conclusions.

我们运用变点理论对这一变化进行了实证分析，得出了一些有意义的结论。

The complexity of bodywork decides variety of it's error. The station and primary factor which cause error is inconstant change and using correlation analysis can find out the primary factor. With an project given, the theory of correlation analysis for dimension variation of bodywork is discussed through correlation analysis and the layer structure of the bodywork,the state in which the error happened can be found out. How to use eigenva...

车体装焊的复杂性决定了误差产生的多因素性，车体制造过程中产生误差的工位和主要因素是不断变化的，采用相关性分析方法从众多的误差根源中准确地发现最主要的误差源；结合工程实践，论述了车体尺寸波动的相关性分析方法的原理，根据测量点的相关性分析和车体焊接工艺的层次结构，可准确地找到产生车体尺寸误差的工位；讨论了如何利用相关系数矩阵的特征值和相应的特征向量判断尺寸波动的模式，指出测量数据的波动主要按最大特征值所对应的特征向量方式波动，引起这种波动的原因是车体误差产生的主要原因，应重点采取措施加以控制；提出了应用计算机进行相关性分析的解决方案。

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。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
