一步

Step 3: In this, the final and most critical step, you need to tilt the main mirror to center its sweet spot in the focuser.

第3步，最后也是最关键的一步。你必须调整主镜的倾斜角度，使主镜的甜点处于调焦座的中央，光轴也要正。

We start with the alphabet, whether it's English or Hindi or whatever.

这是在修习佛法的前进阶段中的第一步，也是最重要的一步。

Imitation is the first and the most important step to study english.

模仿是学习英语第一步也是最重要的一步。

Based on the "one-stage identification", a "two-step compensation" method is put forward, which consists of a linear dynamic compensation subsystem and a nonlinear static correction subsystem.

在一步辨识的基础上，进一步提出基于Hammerstein模型的动态非线性两步补偿方法，包括动态线性补偿和静态非线性校正。

Fourth,the number of nearest neighbor points is an important parameter for the local prediction method,which has an important impact on the prediction accuracy and computation complexity of the local model.

实验结果表明用该方法选取邻近点的局域线性预测方法和局域支持向量机预测方法的一步和多步预测性能较好，在满足预测精度较高的条件下，计算量较小。5。

The results show that the surface microphotograph yielded in multiple-step machining with slow feeding and in one-step compound process is satisfactory, and there are fewer defects, lower deformation and thinner metamorphic layers; while that produced in other processes is quite rough, there are more defects and bigger deformation on the machined surface, and they are detrimental to assembly properties and fatigue life of fastening holes.

结果表明，钻扩铰多步慢进给工艺和一步复合制孔工艺所加工出的表面，平整、光滑、加工缺陷少、晶格变形小、变质层薄；而其它工艺条件下，孔表面微观形貌复杂、加工纹路紊乱、表面缺陷多、晶格畸变大，变质层厚，这些加工状况，对紧固孔的装配性能和疲劳寿命都有很大的影响。

In this section, we focused on the investigation of the condensation, Michael reaction of different aromatic aldehyde with different aryl substituted ketones under solvent-free and PTC conditions, obtained polysubstitutedcyclohexanol derivatives in mordent yield when using TBAB as the catalyst.

通过实验发现，TBAB对该反应具有良好的促进作用，使在液相中需十几个小时甚至几十个小时才能完成的反应，在无溶剂条件下几分钟就可完成，并且使液相中两步完成的反应，而在无溶剂条件下一步就可完成，且产率优良。

With the occurrence of H2/Pd-C and ethyl formic ester,the reduction of the nitro group and the formylation of the amino group could be finished in one step.

但是在甲酸乙酯存在下，用H2/Pd-C对Ⅶ的硝基进行还原，得到的Ⅷ中的氨基可当即被甲酰化，使由Ⅶ到Ⅳ的两步反应一步完成。

Now that you've learned the menu two-step, it is time for the toolbar one-step.

现在，你已经开始了菜单学习的两步，现在是时候到工具栏这一步了。

The methods of one-step prediction and multi-step prediction for deformation are also investigated.

重点讨论了变形序列的一步预测与多步预测的原理、计算方法和特点。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
