四个

They are the deflection w, the rotations of the normal to the undeformed median surface Φx,Φy and the force function F. In the present paper these dependent functions are expressed as generalized double Fourier series with beam eigenfunctions as general terms.

本文中将这四个独立的函数表示为广义傅里叶级数，选用了两个变量分离的梁本征函数之积构成广义傅里叶级数的通项，通过梁本征函数中的待定常数使所选级数预先满足简支、固支或弹性支持边界条件。

On some RISC platforms, of course, you must have doubleword and quadword values aligned in this way.

In nine days, he'll be 21 years old, entering his fourth NBA season, which is exactly how long it took another Lakers high school draftee to win his first championship, a guy named Kobe Bryant.

9天之后，他将年满21岁，进入他在联盟的第四个赛季，准确的说，这也是另一个湖人球员高中毕业被选入 NBA 而赢得了自己的第一个总冠军的用时，那个年轻人的名字叫科比·布莱恩特。

In Dulwich four narrow rooms lead out from the first, echoing the Vasari corridor. As in Florence, the main source of illumination is daylight.

在佛罗伦萨，采光主要来自日光，因此从达利齐画廊四个屋子的第一个开始，到处渗透着瓦萨里画廊的气息。

Secondly, we choose the proportion of shares held by institutions as dependent variable, and we use log of the total asset, volatility, beta, Jensen Index, debt-to-asset ratio, dividend yield, turnover ratio, years listed in exchange and HS300 Index dummy as explanatory variables. Then we set up a multiple regression model. Finally, we use the cross-sectional data from the end of 2006 to the end of 2007Q3 to test the relationship between the explanatory variables and the proportion held by institutions.

具体方法如下：首先，在已有研究成果的基础上，对我国机构投资者的审慎性持股偏好提出了两个假设；其次，以机构持股占个股流通盘的比例为因变量，以公司的总资产对数值、波动率、贝塔值、Jensen指标、资产负债率、股息率、年度换手率、上市年限为解释变量，并在引入沪深300虚拟变量后，建立了多元线性回归模型；最后，采用我国证券市场迎来历史性大牛市、机构投资者发展最为迅猛的2006年末-2007年3季末的四个横截面数据，对各解释变量与机构持股比例之间的关系进行了实证检验。

The aim of the paper is to improve the reliability of HF generator, which is the key to decide the life of HF electrodeless light. At first, I collect and analyze the relative dates, and statistics fault models.

首先进行了与可靠性相关的数据收集与分析，对故障模式进行统计；然后从电路结构、环境应力及容差三个方面进行可靠性分析，从而为关键的可靠性设计提供了依据；接下来的可靠性设计，从电路设计、热设计、降额使用、筛选四个方面逐一解决了可靠性分析阶段发现的问题；最后，我将改良的发生器批量生产，并从中重新收集了可靠性数据进行计算，事实证明改良后高频无极灯的平均寿命已达到6万小时。

She said one reason as to why he chose Elisabeth, his fourth of seven children, was because of her resistance.

她说他选择伊丽莎白，他七个孩子中的第四个，原因之一就是她的抵抗。
