Therefore, it's necessary for us to analyze and judge the dynamic characteristic of our country's investment cycle fluctuation action and the relationship between...

首先，我们采用时间序列的分解方法来描述和测度经济周期和投资周期；然后，我们采用相关分析方法来判断投资波动成分与经济周期成分之间的关联；最后，我们利用结构VAR模型来判断固定资产投资和实际产出之间的关系。文章最后根据上述实证得出结论，并给出相关政策建议。

Therefore, it's necessary for us to analyze and judge the dynamic characteristic of our country's investment cycle fluctuation action and the relationship between investment cycle and economic cycle.

首先，我们采用时间序列的分解方法来描述和测度经济周期和投资周期；然后，我们采用相关分析方法来判断投资波动成分与经济周期成分之间的关联；最后，我们利用结构VAR模型来判断固定资产投资和实际产出之间的关系。

After a brief review about the problems of bit rate control for MPEG video coding, two optimizations are proposed based on MPEG-2 Test Model 5 (TM5) algorithm:①An intelligent integral action is introduced for improving the control precision of bit rate;②After using DCT AC coefficients to define the measure of macroblock and picture coding difficulty, an improvement on target bits allocation is proposed for the decoded picture quality and conformance including scene change, which can ajust the target bits allocation adaptively by their measure.

文中首先对MPEG视频编码比特速率的控制问题作了简要回顾，然后针对MPEG-2测试模型5(TM5)算法进行了以下优化：①引入一种智能积分作用，有利于提高比特速率的控制精度；②采用DCT交流系数定义宏块和图象的编码难度测度，然后提出了优化的目标编码量分配策略，即根据编码难度测度自适应调整图象和宏块的目标编码量，这样有利于提高包括场景变化在内的图象解码质量及其一致性。

According to the peculiar character of waxy crude oil, the action mechanism of Pour Point Depressant is generalized and investigated in this paper, and it is different in different growth period of wax crystal, which is closely related to the chemical constitution according to different type of PPD.

本文首先针对含蜡原油的特殊性，对其添加降凝剂的降凝机理进行了总结与探讨，对影响管输加剂含蜡原油流变性的因素进行了较全面的分析。

I contact bran-new content,first of all I have to comprehend the principles of all procedures and the action of each variable in them,then find out the distinct manners of reserving variables between the flow procedure and the static stability procedures. It is the most difficult to authorize a connective procedure between the two procedures and link and debug the whole procedures.

我接触的是全新的内容，首先必须理解 QR 算法和各程序的原理及各程序中变量的意义，找出潮流程序和静态稳定程序存储变量的异同，编写潮流程序和静态稳定程序之间的接口程序以及连接、调试所有的程序是本毕业设计的难中之最。

First of all, based on the aid of AIS (Automatic Identification System), which can give us the target ship's accurate data and will implement in 2002, we study own ship's relative motion to target vessels, define DCPA and its sign, give mathematic model of collision avoidance, produce the optimal opportunity and action taking of collision avoidance, and obtain a graph of action-taking.

论文首先在2002年将要开始实施的船舶自动识别系统所能提供的准确目标船信息的基础上，研究本船相对于目标船的运动，定义DCPA的大小和符号，推导出船舶避碰数学模型，给出船舶最佳避让行动与时机，得出避让行动曲线图，并且明确最佳避让行动时机不是某个点，而是一个时间段。
