本文以硫酸法钛白粉生产中产生的硫酸氧钛和工业品尿素为原料，采用均匀沉淀法制备了粒度分布窄，分散性好的纳米级TiO_2环境材料。

By way of eight experiments and statistical analysis of loads of overhead crane in actual usese, we have got that the lifing load is stationary, normal and homogeneous Poisson, and got distribution function of lifting load, the load spectrum factor, the rain-flow counting results of stresses and statistical results of location of the trolly, that will provide a large number of datas for reliabilitic design of overhead crane.

通过对八台桥式起重机现场使用载荷的实测试验与统计分析，得出桥式起重机吊重载荷的平稳性、正态性、齐次泊松性、幅值分布、载荷谱系数，以及应力的雨流计数结果、小车位移分布等，为桥式起重机可靠性设计提供了大量的统计数据。

And the results showed that the model constrained iteration inversion methods can get more veliable water contents and distribution from the indued volotage of surface NMR, and these results can be inverted by model constrained inversion from an initial homogeneous water content model.

对无噪音数据，平坦模型和光滑模型约束对反演的含水量分布影响不大；但当数据存在一定的噪音时，平坦模型约束将比光滑模型约束获得更为精确的含水层参数。

Comparison to the well-mixed greenhouse gases, aerosols are highly non-homogeneous in temporal and spatial distribution and have a short lifetime; it is difficult to observe directly. Therefore, more uncertainties about their effects are still existed in the research results.
