查询词典 environment variable

If an external variable declaration does not include a declared type, the type and a matching value must be provided by the external environment at evaluation time.

如果一个外部变量声明不包含一个已声明类型，类型和匹配的值必须由外部环境在求值时提供。

If an external variable declaration also includes a declared type, the value provided by the external environment must match the declared type, using the matching rules in 2.4.4 SequenceType Matching (see 2.2.5 Consistency Constraints ).

如果外部变量声明也包含一个声明的类型，则由外部环境声明提供的值必须与声明的类型一致，此处应用2.4.4 SequenceType Matching中的匹配规则（参见2.2.5 Consistency Constraints）。

ABSTRACT Development of internal combustion engine has been directed by energy saving and environment protection for a long time. Because lean burn technique has great potential to improve fuel consumption and emissions, it has been paid much attention. Variable induction and twice injection [patent no. 98107693. 9] , which have been developed in recent years, have also shown good effect on engine performance.

能源与环境现已成为内燃机技术发展的主导因素，稀薄燃烧由于其能够很好地改善发动机燃油经济性和排放特性而受到广泛重视；可变进气、二次喷油[专利号：98107693.9]等近年来发展起来的技术也表现出良好地改善发动机性能的能力。

This paper described a experiment study of remote sensing systematic analysis on natural resource and environment Change monitoring. Main methods concern changed factor extraction through the brightness statistics, ratio and texture analysis; matching multi-temporal remote sensing data, normalized difference comparison,"brightness" and "greenness" difference analysis of principal components method by using image processing system; updating renewable natural resources changed map through overlaying or partly revising multi-temporal maps by using geographical information system; establishing mathematic model, such as: variable correlation regional regression and tendency surface analysis etc., for researching renewable natural resource change law.

本文叙述了有关资源环境动态遥感监测研究方面的初步探索性工作，主要包括利用图像处理系统，根据专题变化因素的光谱亮度统计进行密度、比值和纹理处理、不同时期遥感信息的复合处理和规一化差值及主成分分析法的"亮度"、"绿度"差值分析；利用地理信息系统，采用覆盖分析和局部更新法进行再生资源变化图件的快速更新，以及为研究再生资源动态变化规律，而进行的多变量相关、区域回归分析方法。

If the LC_ALL environment variable is defined and is not null, the value of LC_ALL shall be used.

若已定义 LC_ALL 环境变数且它不是空值，则使用 LC_ALL 的值。

The value changes for your program only, not for GDB itself. value may be any string; the values of environment variables are just strings, and any interpretation is supplied by your program itself. The value parameter is optional; if it is eliminated, the variable is set to a null value.

这个改变只针对你的程序，不影响 GDB 本身。value 可以是任何字符串，环境变量的值仅仅是字符串，任何解释都是你的程序自己的。value 参数是可选的，如果没有，变量会设为空值。

The regression coefficient inthe model of time series and environment variable is 0.93,and the confidence level is above 99%.

包含时间序列和环境变量的渔获量模型的回归系数为0.93，其置信水平达到99%以上。

These factors have low correlation with mobile terminal\'s velocity, position and environment\'s short time variable.

这些因素与终端的运动、所处的位置、无线信号的传播环境的短期变化关系不大。

The major purpose of the study will explore the effectiveness level of investment decision strategy variables (i.e., these variables are separated in five variable groups: macro economy, consumer, product, market, and risk assessment) affecting investment decision process by three types of risk-taking investors (i.e., risk averter, risk neutral and risk lover investors) in a major banking crisis environment.

本研究目的主要探讨金融风暴期间，三种不同类型的风险承受者(风险规避者、风险中立者、风险偏好者)是否改变投资决策的变数，分别为总体经济、投资者、产品、市场、风险评估的五项构面，对投资决策过程的影响权重。

Parameter PID control strategy fitting for variable velocities and loads was proposed, and the control system's model was established. The control strategy was simulated in MATLAB environment, and the results proved the tracking trajectory of three kinds of gaiting, i.e.

针对控制系统能够适应不同路况的要求，设计了一种适应负载、速度变化的变参数PID控制器，并建立了控制系统模型。
