Under the given condition of acoustic driver, the acoustic field including oscillating pressure, volume flow rate and acoustic impedance in resonator was theoretically reconstructed by using the two-microphone method. The experiment results validate that this method is applicable and accurate for the positions with non pressure antinode and node in resonator. The maximum errors near antinode and node area are up to 12.4%.

在给定双声源条件下，采用双传感器法对该系统谐振管中的声场参数（包括声压、质点速度、当地声阻抗等）分布进行理论声场重构，并通过实验分析，证实了该方法在等径谐振管内非声压腹点和节点处的适用性和准确性，而在声压腹点和节点处的误差最大达到12.4%。

This dissertation deals with theoretical and practical aspects of antithetic and common random numbers for variance reduction in simulation of stochastic systems.

本文对复杂系统仿真中的公共随机数和对偶变量法进行了系统的论述，给出了各种条件下实现方差衰减的理论和实验结果，给出了估计一对具有独立和相关分量的向量函数的响应和期望的最优化证明，且推导出在弱条件下的方差衰减。

The effects of dopaminergic drugs on the secretion of gonadotropin-releasing hormone and luteinizing hormone were investigated by the in vivo injection of dopamine, apomorphine and domperidone into Rana rugulosa at the sexually recrudescing stage, and by radioimmunoassay.

利用在体注射实验和放射免疫测定法，研究了多巴胺能药物对性腺处于再发育期虎纹蛙的促性腺激素释放激素及促黄体激素分泌活动的影响。

This method has some virtues comparing with the former two methods: First, temperature field could be computed without experiments if power dissipation of components is known, that means it can be apriority.

这种方法较采用有限元与有限差分法模拟温度场分布有几个优点，首先，如果元器件功耗已知，温度场的分布可以在不做实验的情况下就计算求得，做到了真正的先验性。

PAHs ratios are used to identify the source of PAHs, the result showed that the major source of 16 PAHs in Urumqi Xinshi district was coal-bustion and vehicle discharges . Mercury in TSP samples were digested by aqua regia and analyzed by AFS analyzer .The results showed that : the concentration of mercury was 0.869-1.91 ng m-3.Compared with other cities in the rest of the world , the concentration of mercury was very high. The concentration of mercury in heating season was lower than that in no-heating season.

对大气颗粒物样品中的汞，采用王水于特弗龙消解罐中加热消解的方法进行处理，稀酸定容后采用原子荧光光谱法对样品中的汞进行测定，测定结果为。869-1.91 ng m-3，与国外城市相比较高；实验测得非采暖期乌鲁木齐大气颗粒物汞浓度的均值高于采暖期颗粒物中的汞浓度，其原因可能是由于随着非采暖期温的升高，长期积累在土壤、水体环境中的汞向大气中释放，附着在颗粒物上，过了燃煤的影响。

The research results would serve as the theory basis and technology support for the commercial aquiculture of U. pinnatifida clone.

上述实验结果将为裙带菜无性繁殖系育苗法的产业化提供理论依据和技术支持。
