Crysalline shape and behavior were investigated by polarizing microscope and wide angle X-ray diffraction spectrum.The results show that the value of impact strength is maximum while tensile strength,flexural strength,modulus and vicat softening temperature are least when the content of β form nucleator is 0.05 phr.

结果表明，当β成核剂的含量在0.05份时，冲击强度达到最大值，而拉伸强度、弯曲强度、模量、维卡软化温度等达到最小值；当β成核剂含量为0.05份以下时，随着β成核剂含量增加，PP中β晶结晶度大幅度上升，同时α晶结晶度大幅度下降；增加β成核剂用量至大于0.10份时，β晶结晶度略为下降，而α晶结晶度上升，但总结晶度随着β成核剂含量增加呈现上升趋势。

The change of frequency, draws the conclusion through observing fish's respiratory rate and coughing: Luo is not the respiratory rate of fish and bright cloud porgy, drop with increase of Cu2+ density, cough frequency increases with increase of Cu2+density; Respiratory rate and frequency of coughing of black carp, appear downward trend after rising with Cu2+ increase of density first.

通过观察鱼呼吸频率和咳嗽频率的变化，得出结论：罗非鱼和彩云鲷的呼吸频率，随着Cu2+浓度的增加而下降，咳嗽频率随着Cu2+浓度的增加而增加；鲫鱼的呼吸频率和咳嗽频率，随着Cu2+浓度的增加都呈现先上升后下降的趋势。

The effects of volatile prices were evident in Exxon's 66 per cent drop in net income to $3.95bn, the steepest fall in profits for more than a decade, and Shell's 70 per cent decline in post-tax profit to $3.24bn.

价格波动造成的影响显而易见：埃克森的净利润下降66%，至39.5亿美元，为十几年来的最大利润降幅；壳牌的税后利润下降70%，至32.4亿美元。

In addition, the number of synaptic sites that express detectable levels of GABARs was decreased by approximately 50% after activity blockade, although there was no reduction in the total number of presynaptic contacts.

另外，突触点的数量表示，在活动阻闭后GABARs可见的水准下降了约50%，虽然突触前接触的总数没有下降。

Macro-control on the healthy development of real estate trend is relatively good, investment growth trend, there have also been a decline , to reduce market supply, there will be a very interesting price scissors: the rate of decline in investment, supply reduction, demand continued to maintain levels.

宏观调控的健康发展房地产的趋势是比较好的，投资增长的趋势，也有一下降，减少市场供给，将有一个非常有趣的剪刀差：的下降速度的投资，减少供应，需求继续保持的水平。

Until recently, the convergence of the Rosen"s arithmetic has been proved. The projection gradient method is the generalization of Steepest decent method to constraint problem. So it does have a faster convergence speed that the fastest decent method . To solve the problem, many researchers have generalizat the well-developed optimization with unconstraint to the Rosen"s gradient method. The conjugate gradient method is one of success to solve the problem.

投影梯度法是最速下降法对约束问题的推广，因此没有较快的收敛速度，为了解决这个问题很多中外学者把发展得比较成熟的无约束最优化算法作类似的推广，其中共轭梯度方法是近年发展的很成熟的方法，它具有计算简单，算法结构好，计算量少，具有良好的收敛性等优点，而Rosen投影梯度法的提出使寻找下降方向变得简单。

From thermal analysis, weight loss occurs pronouncedly at temperatures above 300 oC in air and the residual weight increases with the reaction temperature. The particle size decreases with the increasing ethanol concentration., while the BET surface area decreases when the concentration of water is increased. Pore size measured from the as-synthesized particles is about 2.7 - 4 nm and this becomes slightly smaller after calcination which is about 3 - 5 nm.

TG/DTA中温度上升至约300 oC时，重量开始明显失重，随著合成反应温度上升，最终残留量由1~3%提高为约5~7%，动态光散射粒径分析发现随著乙醇含量增加，煅烧前与煅烧后的粒径尺寸均有下降趋势，随著水含量的增加，比表面积值随著下降，煅烧后的壳层孔隙尺寸约为3~5nm，煅烧前的壳层孔隙尺寸为2.7~4 nm，煅烧后的孔隙度会略为上升。

Later, when unemployment falls,the demands on the public purse fall with it.

其后，当失业率下降时，对公共资金的需求就会随之下降。

In the model of photochemically induced brain ischemia, the putrescine content of cortex increased markedly.

在光化学诱导脑缺血6h和12h时，脑皮质腐胺含量明显增高，精脒和精胺呈下降趋势，在缺血12h时下降显著。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
