Based on minimum resolvable temperature difference channel width of thermal imaging systems and modulating transfer function channel width of photoelectronic imaging systems, a comparative research between the evaluation methods for the general performance of thermal imaging systems is studied through simulation and experiments for an actual thermal imaging system. Good agreement was drawn between the two methods for the general performance valuation of thermal imaging systems.

Gracilis were applied to investigate the effect of proplastid on adaptability, in which such structure was found to be important to the competitiveness during heterotrophic growth in the dark; 2 a new procedure for differential display technology was developed and used to study the influence of plastid on nuclear gene expression, with which it was shown that the loss of plastid could cause remarkable changes in expression of certain nuclear genes.

本文主要有两点突出之处：1）应用裸藻褪色突变株与野生型的生长竞争实验探讨了原质体对于裸藻的适应意义，发现在黑暗环境和异养生长条件下原质体对于细胞的生存竞争有重要作用；2）改进了一种差异显示技术并利用该技术来研究质体的有无对基因表达的影响，证明质体丢失可导致某些核基因表达的显著变化。

When high-intensity ultrasound acts on a liquid medi um, the cavitation can produce a high temperature above 5 000 K and a high press ure about 50 MPa at local sites, accompanied by a forceful impact wave and a jet with 400 km/h. The mechanical action can generate mechanical movement with high frequency whose acceleration can be 1 500 times of gravitational acceleration.

功率超声作用于液态媒质时，空化作用会在局部点产生 5 0 0 0K以上的高温和 50MPa左右的高压，并伴有强烈的冲击波和时速达 40 0km的射流，机械作用会产生高频变化的机械运动，加速度可达重力加速度的 1 50 0倍，这些独特的效应令其在化工领域中的应用越来越广泛。

The theory and application is explained in this paper. Software XMGREDIT5 matching ELCIRC is used to generate unstructured grid, and is considered fit for ocean but rivers. Tidal current is simulated and validated well, and sensitivity of current structure to bathymetry is visible. Affection of wind is qualitatively analyzed here. At the same time the model is improved on as required, like the tidal open boundary which could choose not only long period harmonic constant but also short period harmonic constant and tidal level, and multi-point results and flow field data could be exported effectively with binary results.

本文介绍了ELCIRC的理论及使用；基于其在Linux平台下的软件XMGREDIT5生成全三角形网格并评价其特性，认为XMGREDIT5较适合大范围海域而不适用于河道；应用ELCIRC模型计算了长江口的潮流场并进行验证，结果与实测资料吻合良好，且能较好地模拟出地形变化对水流结构的影响；文中对于风场的影响作了定性分析，同时根据实际需要对模型作了改进，如将仅支持长期资料调和常数的开边界条件改为可选择的短期调和常数边界和潮位边界，使二进制格式结果文件数据输出可以处理多点数据及流场等等。
