In this paper, incising blasting engineering in granite row stone exploitation as the research object, in order to analyze the fracturing mechanism principles of V-shaped notch blasting and the influence of blasting parameter changing to V-shaped notch blasting effect, the elastic-plastic isotropy and multi-notched hole of plane strain model is set up. Dynamical finite element analysis software ANSYS/LS-DYNA is applied to calculate dynamic stress distribution and its change rule of rock around notched holes and between two holes, and dynamic fracturing mechanism is analyzed with fracture mechanics theory.

High precision of data acquisition of accelerometers signal is achieved with V/F convertors.V/F convertors convert accelerometers analog signal into impulse which is transmitted to FPGA and converted digital signal.

为保证其高精度，采用了基于电压-频率转换的数据采集单元来完成加速度计信号的数字化。V/F转换器将加速度计输出的模拟信号转换为脉冲量，FPGA采集脉冲量并转换得到自标定模型所需数字量。

The serotype of 66 strains of Vibrio harveyi isolated from large yellow croaker(Pseudodciaena crocea Richardson) infected by vibriosis was tested in this study. The juvenile large yellow croakers, which cultured in the cage in Xiangshan Bay , were vaccinated with formalin killed V.harveyi of the virulent strains by immerse route , The results were summarized as follow.

本文研究了从患病大黄鱼体内分离66株哈维氏弧菌(Vibrio.harveyi)的血清学性状，并选取了其中的强毒菌株制备成福尔马林灭活的V.harveyi菌苗，对象山港网箱养殖大黄鱼进行了浸泡免疫试验，探讨了V.harveyi的浸泡免疫保护效果，得到了如下研究结果。

The results show that the surface layer of the air-exposed ZrVFe getter is covered with H20, CO2 and hydrocarbons, both Zr and V exist in the oxidized state, and vanadium oxide starts to reduce at 200℃. The activation results in the enrichment of Zr on the getter surface and the formation of the metallic carbides. H2O, CO2 and hydrocarbons sequentially desorb from the surface with the increase of temperature. H2 is the main gas which desorbs above 200℃ and O2 is not discovered. ZrO2 is reduced to near-metallic or metallic state because O in ZrO2 leaves the getter surface through diffusing into getter bulk.

结果表明：暴露于过大气的吸气剂表面覆盖着H2O、CO2及碳氢化合物等，Zr和V主要以氧化态存在；在吸气剂加热激活过程中，V的氧化物在200℃开始还原；激活过程导致表面近金属态Zr的富集以及部分金属碳化物的生成；随着温度的升高，H2O、CO2及碳氢化合物逐渐从吸气剂表面脱附，在200℃以上，主要脱附气体为H2，整个激活过程未发现O2；ZrO2还原为近金属态或金属态，主要是由于ZrO2中的O通过向吸气剂内部扩散而离开吸气剂表面所致。

The results as mentioned above showed that dopants were simultaneously substituted for V〓 and Pb〓.

上述测试结果显示掺杂离子对Pb〓和V〓是同时取代的，只是随着掺杂离子浓度增加，晶体中V〓浓度减小。

The dopings by Al and V had significant effects on the thermoelectric transport performances and could increase the thermoelectric properties of the CrSi_2 single crystal greatly.

Al或V置换掺杂对CrSi_2单晶的热电传输性能有重要的影响，在研究的温度范围内，Al或V置换掺杂会提高CrSi_2单晶的热电性能。

Results: Compared with control group, apoptosis cells increased from 0.5%to 10%(some even to 15%) after 24,48 and 72 h action of -300,-500 and -1 000 V electrets. After action of -500 V PTFE electrets for 48-72 h, fibroblast cells showed characteristic morphological features of apoptosis. These features included chromatin aggregation, nuclear and cytoplasmic condensation and partition of cytoplasm and nucleus into membrane bound-vesicles.
