Those parent abalones of wild or artificial selection with good economic characters must be chosen in order to avoid close breeding.. correct breeding techniques must be adopted to obtain excellent germ cells and larvae. the survival rate and disease resistance of juvenile abalone can be remarkably increased once the further selecting and culturing are carried out. the rejuvenation is realized once a good breeding condition for the young and parent abalones is created, the adverse culturing condition and technical maloperation are reduced or eliminated. the survival rate of the breeding and young abalones increase about 28.9%-31.2%, the survival rate of the grown abalones is high up to 85%-90%.

When cooled, stock made from meat congeals because of the natural gelatin found in the meat. The stock can be clarified with egg whites , and then filled and flavored just before the aspic sets. Almost any type of food can be set into aspics. Most common are meat pieces, fruits , or vegetables . Aspics are usually served on cold plates so that the gel will not melt before being eaten. A meat jelly that includes cream is called a chaud-froid.
这是一款冷菜,常用作&头盘&,制作时需要准备好模具,清汤通常用来做基础汤底(为了让清汤更清澈,制作前我们可以先将蛋白与肉搅在一起,并打上劲儿,这样做出来的清汤会有浓郁的味道和透明度),把明胶放入基础汤中,融化后加入事先准备好的各种肉类和蔬菜(通常会把他们切成块或片),搅拌均匀后倒入准备好的模具中,然后放入冰箱冷藏即可。

SEM and XRD results showed that the bushiest ZnO nanoneedles can be obtained after using H_2O_2 pre-oxidization at the Zn/H_2O_2 ratio of 20mg/ml and themal oxidation at 650℃for 2h and ZnO nanoparticles at the Zn/H_2O_2 ratio of 2mg/ml, and the morphologies were evolved from nanoneedles to nanoparticles between the two Zn/H_2O_2 ratios.
SEM和XRD分析表明,当在预氧化阶段Zn/H_2O_2为20mg/ml时,650℃热氧化2h后纳米锌粉氧化成茂密针状ZnO,当Zn/H_2O_2为2mg/ml时,生成颗粒状ZnO,处于中间浓度时,针状结构依次减少;预氧化微米锌粉无论Zn/H_2O_2比例为多少,850℃热氧化8h后的产物都为栗状ZnO。

Then based on CWMS, we propose a new method to enhance the resolution of seismic traces. Firstly, we divide the seismic signal into proper segments by Gabor molecule-windows adaptive to the signal, where each segment is regarded stationary, and then transform it into the Gabor domain. Secondly, we deal with the amplitude spectrum for each segment to expand the frequency band of the spectrum in the Gabor domain. Finally, taking inverse Gabor transform on modified time-frequency coefficients, we get the high-resolution signal.
然后基于变子波模型,提出了一种新的提高地震记录分辨率的方法:第一步,用自适应于地震记录的Gabor分子窗把地震记录恰当地划分成若干片断,每段内信号近似平稳,然后将地震记录变换到时间-频率域;第二步,在变换域对每个分子窗内信号的振幅谱进行处理以拓宽频带;最后把处理后的时间-频率域函数反变换回时间域得到提高分辨率后的结果。
