Based on Stuart et al.'s electron density evolution equation, the electron density evolution process in fused silica film irradiated by short-pulse laser for τ∈[0.015] ps were studied by means of numerical method. The effects of initial electron density N and laser pulse width τ on laser threshold intensity I and damage threshold fluence. F were analyzed respectively.

基于STUART等人的电子密度演化方程，运用数值模拟方法，研究了脉宽为τ∈[0.01， 5]ps范围内单脉冲激光作用下熔融石英薄膜中电子密度演化过程；讨论了初始电子密度、激光脉冲宽度对阈值功率密度和阈值能量的影响；分析了初始电子密度、激光脉冲宽度对多光子离化及雪崩离化的影响。

The accumulated self-exciting dose for Na-24 is only 1.12 mGy during its average life-time for irradiation of total thermal neutron fluence of 3.6E12 nth/cm^2. Conclusions: Because of the self-exciting dose reduced from neutron activation can be neglected for gamma dose measurement in neutron and gamma mixed field, and the threshold of linear response is 2 Gy, the FWT-70-40 dosimeter not only can be used for high dose rate Co-60 irradiation field and the high energy electron beam for medical purpose, but also can be used for gamma dose measurement in an epithermal neutron beam for boron neutron capture therapy.

型号FWT-70-4OM）剂量计於BNCT高中子通量与剂量的中子、加马混合辐射场所产生的自激剂量，对加马剂量度量干扰可忽略，且对加马的最低剂量限值为2Gy，因此除可应用於钴60加马高剂量辐射场与放射治疗用高能量、高剂量电子射束的剂量度量外，亦可应用於BNCT照射治疗用高能量、高剂量的中子、加马混合辐射场的加马剂量度量。

The effects of initial electron density Ni and laser pulse width τ on damage threshold fluence Fth were analyzed respectively.

研究结果表明，对应于一定的脉宽，存在一个临界初始电子密度，当Ni低于这一临界密度时，Fth不受Ni影响；当Ni高于临界密度时，Fth随Ni增加而降低。

The effects of initial electron density Ni and laser pulse width τ on damage threshold fluence Fth were analyzed respectively. Both the nature of multi-photon ionization and the role of avalanche ionization were also discussed.

研究结果表明，对应于一定的脉宽，存在一个临界初始电子密度，当Ni低于这一临界密度时，Fth不受Ni影响；当Ni高于临界密度时，Fth随Ni增加而降低。

MPI may result in a sharp rise of threshold fluence Fth on \tau, and AI may lead to a mild increase or even a constant value of Fth on \tau. MPI serves the production of seed electrons for AI when the electron density for AI is approached or exceeded before the end of MPI.

MPI结束之前所离化的电子密度如果达到或者超过AI电子密度，则意味着MPI是产生种子电子的主要渠道，此时初始电子密度的影响可以忽略。
