不能分离的

After repeating 5 times, the result shows that the genome DNA can be extracted from the fresh specimens by the methods ,but fail to be extracted from the preserved specimens with the same methods through electrophoresis.

经 5次重复实验，结果表明，用两种方法均能从新鲜标本中获得较完整的DNA ，且DNA得率较高；而对于无水乙醇保存的标本，提取出的DNA用琼脂糖凝胶电泳检测不出DNA条带，说明标本在保存过程中DNA可能发生了变化，致使提取出的DNA量太少或未分离出DNA 。

The results show that quartz cannot react with oleic irons at pH=8-10, because it is difficult to combine with metallic irons. On the contrary, clinochlore can adsorb with oleic ions because there are enough active metallic positive ions between the minerals layers which can combine with clinochlore. The clinochlore can be hydrophobic, and so the separation can be realized finally. At pH=9, the clinochlore removal rate is the maximum, the purity of SiO2 is 99.86%, and the recovery of SiO2 is 35%.

结果表明：在pH为8~10的碱性溶液中，粉石英难与金属阳离子缔合，所以，不与油酸根离子结合；而斜绿泥石解离后层间存在活性金属阳离子，可与油酸根离子发生化学吸附产生疏水作用，因而使用反浮选的方法能有效地实现二者的分离：当pH为9时，斜绿泥石的去除率最高，粉石英的纯度达99.86%，回收率为35%。

Is better than that of using Na〓S merely and the profit per year is over 6, 000, 000 yuan. External potential-control flotation column and The Cu-Mo bulk concentrates flotation separation. With appropriate combination of the principle of sulphide flotation pulp electrochemistry and the technology of flotation column show the advantage over flotation equipment, External potential-control flotation column was studied successfully, laboratory potential-control flotation column was designed and its structural principle, the relationship of electrode structure and the activity of separation, the electrochemistry principle of potential-control flotation column also was investigated.

用具有较强电化学还原能力的无机物（如硫化钠、连二亚硫酸盐等）与能和硫化铜矿物表面发生选择性吸附的小分子有机化合物组合使用、成功地实现了混合精矿体系中黄铜矿的抑制、解决了德兴铜矿铜钼混合精矿浮选分离时、硫化钠用量大、生产成本高，生产指标不稳定的技术难题，研究结果表明，用组合抑制剂3.8kg/t可取代生产中硫化钠45kg/t的高用量，并获得优于单用硫化钠的好指标，年直接经济效益600万元以上。

Although I love the spread, but I know that sense of proportion, I am not bad.

虽然我喜欢分离，但我知道这种平衡的协调的感觉，我不坏（这里语法错的，although后哪能有but？

Shutdown, removed the row fan, fan struck by hand, the sense of rotation of the fan is very flexible, so use flat screwdriver inserted under the roots of the gap fanleaf bend to the will of the fan and fan-Block separation and jumped over the fan, the fan to see in the center of a small arc with several magnet surrounded a round shield-shaped, it is clear that this is the fan motor rotor, while the stator is fixed together with the fan-Block a micro-winding, if the fan and fan blocks together, the micro-coil is inserted to the internal rotor.

关机，将该排风扇拆下，用手拨动扇叶时，感觉扇叶的转动很不灵活，故用平头起子插入扇叶根部底下的缝隙内向上翘，将整个扇叶与扇座分离，翻过扇叶时，看到在扇叶的中心部位有一个用数条小弧形磁铁围成的圆罩形，显然，这就是该风扇电机的转子，而定子是与扇座固定在一起的一个微型绕组，若将扇叶与扇座组合在一起，则该微型绕组正好能插在转子的内部。

The optimal measuring conditions were investigated. The results indicated that the catalytic reaction to Pt and bromocresol purple was the first-order reaction. The apparent activation energy was 217.4kJ/mol and the maximum absorption wavelength of fading reaction was at 434 nm. The linear range of Pt was 0.16-4.0μg/L and the detection limit was 2.5×10^(-11)g/mL. Most of common ions had no interference with the determination, while ten multiples of Ru, Rh and Os had interference with the determination of Pt. Therefore.

选择了最佳测定条件，实验结果表明，催化反应对铂和溴甲酚紫为一级反应，反应的表观活化能为217.4kJ/mol，褪色反应的最大吸收波长为434nm，方法测定R哪的线性范围为0.16~4.0μg／L，检出限为2.5×10^(-11)g/mL，大多数常见离子不干扰测定，10倍以上的Ru，Rh和Os对测定有干扰，可在测定前分离除去。

For if goodness can only be in God, if it cannot exist separate from Him, if He can only bless and sanctify, not by a creaturely gift, but by Himself becoming the Blessing and Sanctification of the creature, then it is the highest degree of blindness to look for any goodness and happiness from anything but the immediate indwelling union and operation of the Deity in the life of the creature.

称永久代祷的人是宗教狂热者是何等毫无理由，至少在单单真实的从神获得启示的生命，是无法得到良善和喜乐，那就不可能同意此说，因为良善无法与神分离而单独存在，除非借他自己所变成有福而圣洁的人否则没人能有此种生命，惟有直接从内住的神得到启示，否则没有高级受造之物，可从其他地方找到良善和喜乐，根据永远的启示：动物怎样需要空气而高级受造物也怎样需要有良善、圣洁和喜乐的本性。

We detected the distribution of lipases in 35 Aeromonas isolates by PCR andphenotypic test using tributyrin as substrate. The positive rates were 100% and 83%,respectively. The lipase activity or associated genes could be detected in the two avirulentstrains, A. hydrophila W1 and A. hydrophila 4332. It suggested that lipase might not be animportant factor in pathogenic mechanism of A.

对本实验室保存的35株气单胞菌分离株进行了脂酶的表型检测和PCR检测，结果分别为83％和100％，特别是嗜水气单胞菌无毒株W1和Ah4332也能检测到脂酶活性或基因，表明脂酶在该菌的致病机制中不是决定性因子。

The results show that magnesium and aluminum theoretically can be thoroughly dissolved from the blast furnace slag by diluted sulfuric acid pretreatment on the blast furnace slag even if the ended concentration of sulfuric acid is 0.001mol/L, while the titanium basically could not be dissolved. Therefore it is theoretically indicated that the separation of the magnesium and aluminum from the slag with the least titanium loss by diluted sulfuric acid pretreatment is possible.

结果表明，采用稀硫酸对高炉渣进行预处理，当终酸浓度即使为0.001mol·l~(-1)时，镁、铝理论上也能全部被酸浸出，而钛在0.001 mol·l~(-1)的酸浓度条件下基本不被浸出，从而从理论上可以说明对高炉渣采用稀酸预处理可以很好的将炉渣中的镁、铝等杂质分离出来，而钛极少被浸出。

In this study, a Y-shaped asymmetric pairs of microelectrodes with a sudden expansion microchannel is used to separate and trap the micro particles in order to get the better inspection.

本研究设计一具不对称电极对的Y型渐扩微管道，先观察微粒子的分离状况，再针对微粒子进行撷取，以期能达到较佳的检测效果。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
