需要

My colleague told me that before design I must know what is the client need. I modified again. But the client still not satisfied.I think it was cause of my lower work experience.I understood design is a serious matter after I observed my colleague. Design should consideration a lot. Design should not be precipitance.

同事告诉我需要先了解客户的需求才能自己再做设计，后来我修改了很多次都没能通过，原因是我的工作经验不足，无法做出迎合客户需求的设计，后来我观察同事们做设计的过程我才明白做设计不能太随便，需要很严谨，需要考虑很多，不能太鲁莽。

To boom and develop social science of philosophy , enhance the ability of administration and the cadre qualities, foster and carry out viewpoint of development, we must do well in prelection of Marxist theory.

讲好马克思主义理论课，是繁荣发展哲学社会科学的需要，是提高党的执政能力和干部素质的需要，也是树立和落实科学发展观的需要。

Only the LORD can make such; but we need such men in the church, and in the world, but specially in the pulpit.

Many researchers have devoted their work to the development of modal analysis extraction techniques in order to obtain more reliable identification of the modal parameters. There are many damping identification methods, but each one has different merit and defect. In order to find which one is the most reliable method with respect to certain characteristics, this thesis focus on how to identify structure's damping in time domain. The following works have been done in this thesis: 1. Investigate four modal analysis methods——the LSCE Method, the Ibrahim Time Domain Method, the Time Domain Collectivity Modal Parameter Method, the Rational Fraction Polynomial Method and improve on the ITD Method in arithmetic.

本文主要做了如下工作： 1、集中研究了四种常用的模态识别方法，即最小二乘复指数法、Ibrahim时域法、时域总体模态参数辨识法及有理分式多项式法，并对ITD法在算法上进行了一定的改进； 2、建立结构动力模型，利用这四种方法在具体条件下识别结构的阻尼，并绘制相应的图； 3、讨论不同的情况下，不同的识别方法对阻尼识别精确性的影响； 4、基于业已明确的阻尼识别的精确性，根据研究的需要，指出在实际的识别过程中，如何选择最佳的识别方法以及识别过程中需要注意的问题； 5、选择最为精确的阻尼识别方法，以导师李书进教授在日本京都大学防灾研究所强震反应实验室所做的一足尺木制结构房屋的动力测试实验为实测模型，识别其阻尼； 6、在本文的最后，尽作者所知，提出了一些需要改进的地方，并对未来的研究方向给出了作者的建议。

The founders of this school knew better...teenage years are something in which to invest, to respect or to trust, and we reassert that knowledge.

这个学校的奠基人懂得：青少年是需要投资、需要尊重、需要信任的，今天我们重申这一点。

Make a decision to relinquish the need to control, the need to be approved, and the need to judge.

作出决定，放弃控制的需要，被认可的需要，判断的需要。

Then I need to make sure I've got the symlink set up correctly in each runlevel where I want it to run, and if I happen to need it to execute between two scripts that are consecutively numbered, I need to do some symlink renumbering (e.g., if S10xxx and S11yyy exist, and I want zzzz to run between, I need to resymlink one of those files to squeeze zzzz between them).

然后，我必须确保在每个要运行这个服务的runlevel中正确地设置好符号链接。假如恰好这个服务需要在已经连续编号的两个脚本之间运行，我就需要做一些对符号链接重新编号的工作(例如，S10xxx和S11yyy已经存在，而我想让zzzz在它们之间运行，我就需要对前两者之一重新建立符号链接来把zzzz挤进去)。

The water storage function of condenser is the must not only for gathering and storing condensed water, various water repellence of thermal system, exhaust steam and chemical feedwater, but also for cushioning dramatically changing turboset flow during the operation, improving the stability of system regulation and ensuring the essential water-absorption pressure head of condensation pump.

凝汽器的蓄水作用既是汇集和贮存凝结水、热力系统中的各种疏水、排汽和化学补给水的需要，也是缓冲运行中机组流量急剧变化、提高系统调节稳定性的需要，并且是确保凝结水泵必要的吸水压头的需要。

Nutrition of each stage during reproductive cycle and reproductive performance of sows are intimately interrelated with each other.

要充分发挥高产仔母猪的遗传潜力，需要相当严格的饲养管理条件，其繁殖周期的每个阶段都要制定相应的营养需要和饲养管理标准，以满足其各种营养物质尤其是能量和蛋白质的需要。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
