zemax源码： This DLL models a standard ZEMAX surface type, either plane, sphere, or conic The surface also demonstrates a user-defined apodization filter The filter is defined as part of the real ray trace, case 5 The filter can be used at the stop to produce x-y Gaussian apodization similar to the Gaussian pupil apodization in ZEMAX but separate in x and y. The amplitude apodization is of the form EXP[-(Gx(x/R)^2 + Gy(y/R)^2)] The transmission is of the form EXP[-2(Gx(x/R)^2 + Gy(y/R)^2)] where x^2 + y^2 = r^2 R = semi-diameter The tranmitted intensity is maximum in the center. T is set to 0 if semi-diameter < 1e-10 to avoid division by zero.

SYN Flood是当前最盛行的DoS（拒尽服务进攻）与DDoS（散布式拒尽服务进攻）的方法之一，这是一种利用TCP协议缺点，发送大批伪造的TCP连接请求，从而使得被进攻方资源耗尽（CPU满负荷或内存不足）的进攻方法。(SYN Flood is one of the most popular DoS (refuse to do service attack) and DDoS (Distributed refuse to do service attack), which is a Use the TCP protocol shortcomings, sending a large number of forged TCP connection requests, making the offensive resource exhaustion (CPU full load or memory) Offensive....)
