For reasons of backward compatibility, when a local variable declaration specifies var as the type and a type named var is in scope, the declaration refers to that type; however, a warning is generated to call attention to the ambiguity.

由于向后兼容性的原因，当一个本地变量声明标示为 var 作为类型并且在范围内已经有了一个 var 的类型，那么声明指向的是该类型；然而，编译器会产生该种混淆的警告。

When a local variable declaration specifies var as the type and no type named var is in scope, the declaration is an implicitly typed local variable declaration.

当一个本地变量声明标示为var作为类型并且没有var类型名称在范围内，那么这个声明被视作隐式类型化的本地变量声明。

In view of the peaked and fat-tailed characteristics of financial return data distribution and its effect of clustering fluctuation and especially the "leverage effect" of fluctuation on VaR estimates and some efficiencies when estimating VaR with various assumptions of return data distribution,a semi-parameter approach based on EGARCH-VaR model is developed.

在综合考虑了金融收益数据分布的尖峰厚尾特征及其波动集群性，尤其是其波动的&杠杆效应&对VaR估计的影响以及各种假定收益率分布在计算风险价值时存在不足的基础上，提出了基于EGARCH-VaR的半参数方法，并且与正态分布和t分布假设下的GARCH模型的VaR计量方法进行比较，通过实证分析，并利用后验测试，表明基于EGARCH-VaR的半参数方法对风险价值的测度优于正态分布和t分布假设下GARCH模型的VaR计量方法。
