At 4 wk, the cells in the liver bud migrated into the domain of transversum mesenchyme, where endothelial cells began to form vascular structures, and branched to form a number of hepatic cords.

结果：3wk时靠近肝芽的间充质中的血管内皮细胞多，而肝芽内未见血管内皮细胞及造血细胞：4wk时，肝索形成处可见较多正在形成的新生血管增多，肝索间开始出现少量的造血细胞：5wk时肝索间出现原始的肝血窦结构，血窦内造血细胞的数量较4wk明显增多。

Trehalase plays an important role in glycogen accumulation in the formarion of diapaused eggs. At the beginning of diapause, glycogen phosphorylase is the key enzyme to glycogen decomposition and the formation of sorbitol and glycerol, whereas at the stage of diapause termination, NAD-sorbitol dehydrogenase is the key enzyme to sorbitol decomposition and glycogen re-synthesis.

在滞育卵形成过程中，海藻糖酶对糖原的积累起着重要的作用；在滞育开始时，糖原的分解与山梨醇、甘油的形成，糖原磷酸化酶是关键酶；在滞育解除时，山梨醇的分解与糖原的再生成时山梨醇脱氢酶(NAD-sorbito1 dehydrogenase)是关键酶。

The thermal property studies indicate that the mass loss of compound B was 54.39% at 242.2~750℃, and when the temperature was 1000℃, there was 25.11% char residue left, which showed that the title compound has a good thermal stability and char forming capability. Using acetonitrile as the solvent instead of trichloromethane or 1, 2-dichloethane gave higher yield. During the synthesis, the yield was very low when triethylamine was used as acid acceptor alone, and when a little amount of 4-dimethylaminopyridine was added at the same time, the yield could be 81%.

结果表明，所合成的化合物B的结构与预期的结构一致；热性能研究表明，化合物B在242.2~750℃质量损失为54.39%，1000℃时仍有25.11%的炭残渣，显示出优异的热稳定性和成炭性；在相同反应条件下，用乙腈作为溶剂的反应产率比使用氯仿和二氯乙烷为溶剂的高，并且在合成过程中，单独使用三乙胺作为缚酸剂时产率很低，而当同时加入少量4-二甲氨基吡啶时，产率可达81%。

Accordance with volume of biogas actually using requirement so that actualize supporting facilities, it can keep the pressure contant of biogas using for long time, the floating cover upside of body be pressurized, when the floating cover biogas digester fermenting to produce biogas will drive the soft PVC floating cover rising up with biogas storage, if user make use of biogas in case of biogas stove which the biogas pressure will be drop below in conjunction with floating cover will synchronous drop, when the floating cover has full of biogas which supernumerary of biogas automatic overflow to outside from bottom side of floating cover, it can not be appear with over high pressure thereby cause the tympanites of floating cove burst or biogas pipe burst and never has such phenomenon happen, the floating cove type biogas digester has reliable safe security.

根据沼气实际使用需求用量来做相应配置，可以保持长期在恒压状态沼气气压，浮罩顶部是密封的，当浮罩式沼气池发酵时所产生的沼气使浮罩上升并储存沼气，如果用户在用沼气炉灶用气时沼气压力将随之下降的同时浮罩也随着气压的下降而降低，当浮罩充满沼气时多余的沼气会自动从浮罩底部溢出，不会出现因气压过高造成鼓池、爆裂或爆管现象发生。浮罩式沼气池具有非常可靠的安全保障。

Multiple linear regression is the simplest way to build the relationship between the several explanatory variables and response variable. However, MLR often causes the estimated regression coefficients unstable or even unaccessible when the number of explanatory variables is more than that of objects. Especially, the explanatory variables are highly intercorrelated which called multi-collinear data. Therefore, many methods have been developed to analyze multi-collinear data, such as variable selection methods, ridge regression, principal components regression and partial least squares regression.

当要同时建立多个解释变数与反应变数间的关系时，最简单的方式是以复回归来处理，但是当解释变数数目远多於样本数，或者变数之间具有高度相关性时，会使得回归系数的估计变得不稳定甚至无法求得，这样的资料又称为共线性资料，在面临这样的资料时可以利用变数选取的方式降低资料组的维度，或者以脊回归、主成分回归及净最小平方回归等方法来灭种共线性的干扰。

God from all eternity did, by the most wise and holy counsel of his own will, freely and unchangeably ordain whatever comes to pass: Eph 1:11 Ro 11:33 Heb 6:17 Ro 9:15,18 , yet so, as thereby neither is God the author of sin, Jas 1:13,17 1Jo 1:5 , nor is violence offered to the will of the creatures, nor is the liberty or contingency of second causes taken away, but rather established.

Ac 2：23 Mt 17：12 Ac 4：27，28 Joh 19：11 Pr 16：33 1 ）神从永恒那样，由最明智的和神圣的律师，他自己的意志，自由和unchangeably阿拉维无论说到通过：弗1时11滚装11时33以弗所书6时17滚装9：15，18 ，但这么，从而既不是上帝的作者单仲偕， 1990年1：13，17 1jo 1：5 ，也不是暴力提供给会的动物，也不是自由的或应急的第二个原因带走，而是确立。

Interest state must be kept up to date at all times - whenever a downloader doesn't have something they currently would ask a peer for in unchoked, they must express lack of interest, despite being choked.

当某个peer需要下载某个文件块时，它应该向状态时unchoked的peer明确表示它需要的文件块，同时忽视那些状态时choked的peer。

Results The patients with the serum potassium concentration over 4.1 mmol/L accounted for 19.4 % in the group A, 37.7 % in the group B, 94.9 % in the group C at the aorta unclamped.

结果 方法1组在主动脉开放时血清钾＞4.1mmol/L者19.4%，方法2组主动脉开放时血清钾＞4.1 mmol/L者为37.7%者，方法3组主动脉开放时血清钾＞4.1 mmol/L者94.9%。

Rats in the treatment group were injected with 10 μL of human insulin of rapid gene synthesis （1 ×10%5 U/L）immediately after unclamped the bulldog clamp and reperfusion, while rats in the sham-operation group and control group were injected with normal saline at the same volume.

分别于全脑缺血再灌注1，3，5d，假手术组（1只／时相点）、缺血对照组（6只／时相点）、胰岛素治疗组（6只／时相点）大鼠断头取脑，行免疫组化染色，光镜下观察海马CA1区神经元酪氨酸羟化酶和多巴胺-β-羟化酶表达的变化。

"In fact, one way to think about that when we're on the International Space Station and all the lights are on when we look outside, it's very much like trying to look at the stars when you're in Boise. You can see some, but then if you go up high in the mountains, up to McCall, and you have all the lights out, that's what it will be like once we undock from station and we can turn all our shuttle lights out, and also for the station folks they can turn all their lights out."

事实上，有一种情况是我们可以想到的：在灯火辉煌的国际空间站向外看时可看到一些星星，这与你在博伊西费劲看到的是相类似的，，但是当你在山上一直往上爬，爬至与McCall一样高时，你就会忽略所有的灯光，这与我们一旦驶离空间站时所有梭子灯灭掉的情况是一样的，并且对于空间站的人来说，他们也可以把他们的灯都熄灭。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down
