不分离的

They can reach 72.04% and 84.5% separately(P.05). 2. The methods such as Percoll uncontinuous density gradient centrifugation, isolation according to the different adhesiveness can be used to isolate and purify rabbit SSC effectively. Spermatogonia mainly distribute between the gradient 27% to 35%(density between 1.0410g/ml to 1.0508g/ml).

Percoll 不连续密度梯度离心和差异粘附等方法可以有效的对兔精原细胞进行分离纯化，其中精原细胞主要分布于密度梯度为27%-35%(密度 1.0410g/ml~1.0508g/ml)的带间，此带中精原细胞的纯度平均达到 60.42%(P.01)。

Two molecular forms of Xenopus hatching enzyme, 60kD and 40kD molecules, was obtained during preparation and purification. Both of them were verified as the hatching enzyme molecules, using anti GST UVS.2 antibody as the probe. 60kD molecule was digested or autodigested easily into 40kD molecule during purification. It was indicated that 40kD molecule was probably derived from 60kD molecule with its two CUB repeats lost, and the two CUB repeats may play an important role in recognizing and/or modifying of the molecular structure of vitelline envelope.

在分离纯化非洲爪蟾孵化酶时，得到了60kD和40kD两种分子，用孵化酶的特异性抗GST-UVS.2抗体进行Western杂交的结果证明二者均为孵化酶分子。60kD分子很不稳定，在纯化过程中极易降解，40kD分子可能是由60kD分子经过降解或自身降解丢失了两个CUB重复区而形成的，而CUB重复区很可能在对受精膜分子结构的修饰或改造中具有重要作用。

Results17 fatty acids were identified in the seed of Zizyphus jujuba Mill, the contents of the identified fatty acids made up to 95.33%, the unsaturated fatty acids were 80.20% and saturated fatty acids were 15.13%.

结果由酸枣仁中分离鉴定出 17种脂肪酸，占脂肪酸总量的95.33 %，不饱和脂肪酸占脂肪酸总量的80.20 %，饱和脂肪酸占脂肪酸总量的15.13%。

It was isolated from the mosquito stomach HIV, found that absorption of the mosquito's blood after AIDS patients, HIV can survive in the mosquito stomach three to four days, but the amount of virus in mosquitoes can cause the number of HIV transmission is not clear, and the mosquitoes In a suction blood, at least three to four days no longer vampire bites, and some died soon; Some people also said: mosquitoes but the remnants of blood containing HIV will be transmitted to humans.

有人从蚊子胃内分离出HIV，发现蚊子吸了艾滋病病人的血之后，HIV可在蚊子胃内存活3~4天，但蚊子体内带毒量的多少才可引起HIV传播尚不清楚，而蚊子在吸一次血之后，至少3~4天不再叮咬吸血，有的很快死去了；又有人说：蚊子嘴上残留的血液含有HIV会传染给人。

Our proposed method, which is a kind of optimization approach in time domain, doesn't have taper effects that result from window filter band and attenuates artifacts.

该方法是一种时间域最小平方优化分离波场的方法，不存在其他滤波方法阈值滤波器边界的影响，减少了因镶边问题带来的假象。

There will be no sad good-byes , As our love blossoms sweeter.

当我们的爱情之花更加甜蜜的时候，我们的未来不会有分离。

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。

By the bio-assay directed fractionation of the volative constituents.dimethyl disulfide,allyl methyl trisulfide,allyl methyl sulfide and diallyl disulfide were found to increase the beating rate and beating amplitude in a standard medium,but the compund 2-pentanone without sulfide did not affect either of them.

从具有生物活性的挥发性提取物中分离得到的二甲基二硫、烯丙基甲基三硫、烯丙基甲基硫醚和二烯丙基二硫对培养心肌细胞心率和振幅均有不同程度的增强作用，而不含硫的2-戊酮则没有作用。

The stationary flexible chute system for concrete-conveying is more convenient than the common chute because of its flexible,adjustable and negative-pressure damping behaviours,the end of this flexible chute is uneasily blocked up,and the aggregate of conveyed concrete is quite few separated;good application prospect of this chute system is expected.

固定式软管溜筒系统由于具有柔软可伸缩性和负压阻尼的特点，与普通的钢管溜管系统相比，具有不堵管、终端骨料分离较小的特点，是一种具有应用前景的新型混凝土运输手段。

If you buy the album with glue, but you also do not want to stick paper cutting die can be used will be transparent cellophane paper-cut separation of the glue.

如果你买的是带粘胶的相册，但你又不愿意将剪纸粘死，可以用透明的玻璃纸将剪纸同粘胶分离。

I didn't watch TV last night, because it .
