在操作中

Because of fault in operation and the precision of instrument,the defect error and accidental error are involved in the procession of data collection,the defect error that are brought by mistakes of people and influence of outside is large,the contingency error that are inevitably and randomicity is little.

在采集数据过程中，由于某些操作或仪器原因，往往使数据中包含人为错误，或外界干扰产生的量值较大的"过失误差"以及不可避免的带随机性质且量值较小的"偶然误差"。

Beckmannia syzigachne had poor adaptability and competition ability in rape or wheat field with no-herbicide application in history, but would become dominant specie in water logged winter fallow, leading to yield loss of rape and wheat after a few years.

在实行正常农事操作的稻茬油麦田中，与其它主要杂草种群相比，其自然竞争力弱，难以成为群落的优势种。但其具有&喜湿性&的特点，在冬季常常积水的休闲田中，发生量可大幅度上升。

Information is stored in mass storage systems in large units called files. A typical file may consist of a complete text document, a photograph, a program, or a collection of data about the employees in a company. The physical properties of mass storage devices dictate that these files be stored and retrieved in multiple byte units. For example, each sector on a magnetic disk must be manipulated as one continuous string of bits. A block of data conforming to the physical characteristics of a storage device is called a physical record. Thus , a file stored in mass storage will typically consist of many physical records.

在大容积存储系统中，信息是以称为文件的大的单位存储的，一个典型的文件可以是一个全文本的资料，一张照片或一组关于公司员工的数值，大容积存储系统的物理特性表明，这些个文件是按照许多字节为单位存储的检索的，例如，磁盘上每个扇区必需作为一个持续的二进制位串进行操作，符合存储系统物理特性的数值块称为物理记录，因此储存安放在大容积存储系统中的文件通常包罗许多物理记录。

Busparallel expansion and pipeline technique are adopted to improve the average inputand output speed of recorder based on FLASH memory. 2 A concept of 'cluster' isintroduced. The using state message of each cluster is loaded in the spare area,following the target datum, to keep the pipeline sequence of multiple clusters' loading, which guarantee the average input speed of system. 3 Based on the using statemessage of every cluster, the Cluster Allocation Table established in memory enablethe system to manage the recorder flexibly in high speed, similar to a file managementsystem. 4 PowerPC 8245 based embedded system, along with Vxworks real-timeoperating system is introduced to make the system more easier to be applied to theprojects in the future.

本文所述的关键技术特点主要包括：采用了并行扩展以及流水线操作技术以提高基于FLASH芯片的存储区平均输入输出能力；引入了&簇&的概念，为了保证连续写入过程中的流水线顺序，系统向存储区加载每一簇有效数据后，紧接着还将向相应簇的空余区中加载该簇的使用状态信息；根据所有簇的使用状态信息在系统内存中建立&簇分配表&，可以支持系统快速灵活地管理存储区，即，类文件化的数据管理；采用基于PowerPC8245的嵌入式计算机硬件系统及基于Vxworks的嵌入式实时操作系统，提高了系统的整体性能及系统研发的延续性。

To eliminate the disturbance of the noise (particularly the pulse noise and salt-and-pepper noise influence which causes by equipment and transmission) in image processing, a smooth operation is needed. In this paper we have analyzed several smooth operation methods and improve median filter method by a directional way to reduce the detail loss of smoothing process.

为在图像处理过程中去除噪声的干扰（尤其是由设备和传输引起的脉冲噪声和椒盐噪声的影响），首先对图像进行平滑操作，本文对常用的几种平滑滤波方法进行了分析，选择使用中值滤波方法，并使用边缘的方向信息对其进行了改进，以减少平滑过程中的细节损失。

If only on the K line combinations to judge the short-term direction of the operation, will inevitably face more uncertainty risks, but also tried to Rs easily formed the habit of a strong rise in the often away prematurely in the hands of profit-chips, in the mining market rebound due to the strong efforts to weak difficult to grasp , it is easy bearing.

如果仅仅依靠日K线的组合来判断短线的操作方向，难免会面临较多的不确定性风险，同时也容易形成追涨杀跌的习惯，在强势的行情中往往会过早抛掉手中的获利筹码，在弱市行情中又由于反弹力度时强时弱难以掌握，很容易被套。

The cars used machine dog digital simulation processing system following features : digital interface design and development of the system platform is based on environment through programming to achieve connectivity and the use of the interface between the basic attributes to achieve a blank map, parts map reached parts of the simulation processes shaped the cutlery trails simulation, achieving linear simulation for basic processing and operation will be completed on the digital processing used digital simulation commands conservation functions.

Based on the idea of type systems, this paper reengineers a new set of type expressions and a type system for machine code of Intel/x86s infrastructure Although machine language program is a binary untyped code, types of its registers and memory exist implicitly in semantics of instructions The type inferring algorithm built on type systems can statically infer safety of the machine code The machine language discussed includes some of important characters, such as jumps, function call, return, and so on, and shows that the approach can be applied to type checking for low level code of other infrastructures

根据类型系统思想，为Intel/x86体系结构的机器语言重新定义了类型表达式并建立一套类型系统机器语言代码虽然是一种无类型的二进制编码，但其类型信息被隐含在指令的操作语义中，利用建立在类型系统基础之上的类型推理算法可以静态地推理机器代码的安全性由于所讨论的机器语言包含了跳转、函数调用和返回等主要指令，因此，这种静态检查方法可广泛应用于其他体系结构的低级语言代码的检查中

It was suggested that the raw waste liquid A was conditioned with hydrogen chloride to pH 4, then dosage of ferric chloride as 1200 mg/L for the rapid mixing 1 minute and slow mixing for 30 minutes, then after further settled in the clarifier for at least 1 ~ 2 hours, the effluent was treated by the oxidation with chloric acid for no more than 10 minuts in the dosage of 50 g/L or the correspond ORP value of 334 mV.

处理废液A在实厂操作流程中建议最先以降低pH值至4，在利用1，200mg/L氯化铁做为混凝剂，经由1分钟快混(100rpm)及30分钟慢混(10rpm)后，藉由混凝沉淀去除废液中之胶体，再使用50g/L氯酸钠作为氧化剂，反应时间为5分钟，氧化残余之COD，再利用ORP值为是否达334mV，藉以判断COD是否达终点。
