试验结果表明，甲基对硫磷在天然地表水中生物降解一级速率常数为：-0.053 d-1；在天然地表水沉积物中生物降解一级速率常数为：-0.295d-1；在地表水中生物降解半衰期为：13.1d；在地表水沉积物中生物降解半衰期为：2.3d。

The diagnostic of DT fuel plasma areal density in the direct-driven implosion experiments on SG-Ⅱ laser facility has been performed by measuring the number of recoil D and T produced by 14MeV neutron′s scattering. The particles of recoil D and T were detected by CR39 solid-state nuclear track detector.

在神光Ⅱ基频光直接驱动内爆实验中，利用CR39径迹探测器测量了DT靶丸释放出的 14MeV中子弹性散射后逃逸出燃料的反冲D核和反冲T核的数量，实现了激光聚变实验中燃料面密度〈ρR〉的诊断。

Having studied the digital down-conversionprocess of IF signal before the base band process which follows A/D conversion in wireless communication,the paper puts forward a new idea of utilizing the FPGA to realize multi-channel digital signal DDC.Through analyzing the features and performances of CIC filters,HB filters and multiphase-filter,we combine them with decimators and decimate the A/D data,thus reducing the digital signal rate and the load of DSP when processing the base band signal.

软件无线电技术是在通用的开放式无线电智能平台上，通过安装不同的软件来完成各种通信功能，其结构的基本特征之一就是使A/D变换尽量靠近射频端，目前的方案是在中频对模拟信号进行数字化，对中频数字信号进行下变频处理，使数字信号量降低到高速DSP能够处理的程度[1]。

MethodsSixty Wistar rats were divided into 2 groups randomly: normol group(n=12), and model group(n=48).The model rats were fed with high fat-sugar diet for 6 weeks, then fed with adenine(100 mg·kg-1·d-1) and ethambutol(250 mg·kg-1·d-1) for 2 weeks to induce the IR and hyperuricemia model.

方法选用 60只成年Wistar雄性大鼠，随机分成正常对照组（12只）和模型组（48只），模型组给予高脂高糖饲料餵养6周，6周后再用腺嘌呤〔100 mg/kg·d）〕加乙胺丁醇〔250 mg/〕灌胃2周，造成胰岛素抵抗并高尿酸血症的大鼠模型。
