说明：  FMCW雷达进行SAR成像，该代码可观察距离徙动现象(FMCW radar is used for SAR imaging, and the code can observe the range migration)

说明：  无限制版，极影工作室的看家产品之一，交易两个货币兑进行对冲。经过实际测试，EURUSD和GBPUSD的盈利效果最好，AUDUSD和NZDUSD不是很好。按理说这两组关联都不错才对，可能是测试期间行情所致，因为无法回测双币以上ea，实盘模拟测试。(One of the Housekeeping Products of Polarshadow Studio is trading two currencies to hedge against each other. After actual testing, EURUSD and GBPUSD have the best profitability, while AUDUSD and NZDUSD are not very good. It is reasonable to say that the correlation between the two groups is good, which may be due to the market during the test period, because it is impossible to retest the EA above two coins, a real-time simulation test.)

用J2ME实现的俄罗斯方块，界面什么的都很好 ，应该有借鉴价值。-rissua block by J2ME,with good interface,should have value of study.

双重差分估计 双重差分模型（difference-in-difference，DID）近年来多用于计量经济学中对于公共政策或项目实施效果 的定量评估。 通常大范围的公共政策有别于普通科研性研究，难以保证对于政策实施组和对照组在样本分配上的完全随机。非随机分配政策实施组和对照组的试验称为自然试验（naturaltrial），此类试验存在较显著的特点，即不同组间样本在政策实施前可能存在事前差异，仅通过单一前后对比或横向对比的分析方法会忽略这种差异，继而导致对政策实施效果的有偏估计。(Quantitative evaluation of policy or project implementation effect. Generally, a wide range of public policies is different from general scientific research, and it is difficult to ensure that the sample allocation for the policy implementation group and the control group is completely random. The non-randomly assigned policy implementation group and the control group are called natural trials, which have significant characteristics, i.e. there may be prior differences between the different groups of samples before the implementation of the policy, and this difference will be ignored only through a single pre-and post-comparison or horizontal comparison analysis method, which leads to the policy. Biased estimation of implementation)
