The experiment results indicate that V-system is an effective tool used to reconstruct complicated geometric information with both continuous and discontinuous signals. This is the essential difference among V-system, the classical complete orthogonal system with continuous functions and Walsh and Haar system which include intense discontinuous functions.

Climatic gradients were based on data sets from 841 meteorological stations throughout China. Definitions for floristic distributional patterns were based upon the work of Prof. Z. Y. Wu. Most of these floristic distributional patterns were strongly correlated with the geographic gradients in climate, except for cosmopolitan, cultivated and invasive genera. Tropical genera form a large fraction of the total genera (ranging from 0.84% to 94.38% in the regional floras) with the highest proportion in southern Yunnan and Hainan Island. Tropical genera occur predominantly in southern China of 0° N latitude and decreased with increasing latitude, as would be expected. Interestingly, the disjunct Tropical Asia and Tropical America distribution were not restricted to southern latitudes. Temperate genera account for 5.1% to 98.83% of the total genera in regional floras with the highest proportion in the province of Xinjiang. Most of these genera followed geographic gradients in climate as expected (temperate genera conspicuously dominate the landscape at higher latitudes), except the East Asian and North American disjunct distribution, Eastern Asian distribution and Chinese endemic distribution. Generally, most plant genera demonstrated some correlation with climatic and geographic gradients. The most important gradients were those of annual air temperature and precipitation. A small fraction did not demonstrate significantly particular pattern:"Cosmopolitan","East Asian and North American disjunct","Eastern Asian" and "Chinese endemic" distributions. The North Temperate distribution had the highest correlation with mean annual air temperature and precipitation.

The research leads to following conclusions: A The age of the ferromanganese contacting with the upper phosphate layer is 14.9 Ma; B The crust had been grown continually without sedimentation interruption since 14.9 Ma, suggesting that it can be used to rebuild the environment of palaeo-ocean and palaeo-climate from 14.9 Ma to 0 Ma; C The sedimentation interruption between the ferromanganese and the upper phosphate layer lasted around 4 Ma; D Between 19 Ma and 22.7 Ma, great phosphatization event happened in this area, which might cause the sedimentation interruption from 22.7 Ma to 14.9 Ma; E The ferromanganese crust began to grow from 75 Ma.

according to the users′ actually demand for uninterruptible power supply for loads,the internal structure of digital generator is analysed and the reason for its uninterruptible function can′t be achieved.a design of the uninterrupted power supply system which transformed from the digital generator is proposed.the system uses the inverter of generators,ac through inverter for loads,at the same time,charges the battery as ac is normal.inverter the battery dc converters to ac for load,meanwhile,starting generator,when power failure.the system applies uninterruptible power for load,whether the ac is normal or abnormal,and design voltage and frequency stabilization,output zero-interrupted,battery charging and discharging management.without requiring purchase an uninterruptible power supply separately,this design can avoid duplication of investment and wasting of resources.

快速安全提高汽轮发电机转子检修质量。。。摘要：针对用户对负载供电不间断的实际需求，分析了数码发电机的内部结构及其不能实现供电的不间断性能的原因，提出一种由数码发电机改造组成的交流不间断供电系统的设计方法。该设计利用发电机内部的逆变器，在市电正常时，由市电经过逆变器给负载供电，同时给蓄电池充电；在市电断电时，一边启动发电机，一边由蓄电池的直流电通过逆变器转换成交流电供负载使用，实现无论市电正常还是异常，系统对负载提供不间断电源。设计对市电进行稳压、稳频、输出零切换、蓄电池的充放电管理等新功能。此设计无需单独购买不间断电源，避免重复投资和资源浪费。

The complexity of the 660km discontinuity beneath MDJ shows that the subducting slab materials are piled above the discontinuity, and the existence of this discontinuity beneath HIA shows that the effect of the subducting slab on the discontinuity is very weak.

The existences of these discontinuities show obvious regional characteristics that,(1) at the northern Izu-Bonin which is north to latitude of 33°, the SV-P converted phases following the phases from the 660km discontinuity are relatively weak,(2) at the southern part which is south to latitude of 29°, all phases are relatively strong, even some phases' amplitudes are comparative with those from the 660km discontinuity, and (3) at the part of Izu-Bonin between the latitude between 30°and 32°, all converted phases are relatively weak except the clear phases from the 660km discontinuity.

从各地震的波形叠加结果看，这些间断面的存在情况明显具有区域性特征：在北部，北纬33°以北在来自660km间断面的转换震相之后出现的SV-P转换震相相对较弱；在南部，北纬29°以南则各转换震相相对较强，有的幅度可以与来自660km间断面的转换震相的幅度相比；而北纬30°～32°之间除了来自660km间断面的转换震相存在比较清晰以外，后至的转换震相都相对较弱。
