一步

Using a critical realist perspective, our theory explains the process of change as a three-stage cycle in which the ostensive, performative, and material aspects of organizational elements interact differently in each stage.

用一个挑剔的现实主义观点，我们的理论解释了变革的过程作为一个三步循环在组织因素的实例，行为和物质方面，在每一步都有不同的交互影响。

It indicates that some of petroleum coke combustion agrees with one step model while other of petroleum coke combustion agrees with two steps model.

燃烧的热重分析结果表明，有些石油焦的燃烧符合一步反应模型，有些石油焦的燃烧符合明显的两步反应模型。

When you'll be clear about what you want to do, proceed to the next step.

弄清楚这步之后，看下一步。

Step 2: Click on the Create a restore point radio button and then click Next.

第2步：点击创建一个还原点单选按钮，然后单击下一步。

But the "two steps forward, one step back" cliché does not countenance such retrogression.

不过「进两步，退一步」的老调是不会容许这样的退步。

Firstly,"clean steel" areas are identified and the steel composition determined. In the second step, the average composition across the entire length of the scan is determined. In the final step, the average slag composition is determined by means of a difference calculation.

首先，辨别出"干净"的钢区域，测定出钢的成分；第二步，测定出扫描总长度范围内的平均成分；最后一步，通过差减法计算出炉渣的成分平均值。

As to system＇s uncertainty such as time varying characteristics, grey multiple step error correction method took the place of the conventional single step error correction method.

针对对象特性时变等不确定因素，该文以灰色多步误差预测校正替代原有算法的当前一步误差校正，可以更为有效的克服模型失配等因素的影响。

As to system s uncertainty such as time varying characteristics, grey multiple step error correction method took the place of the conventional single step error correction method. The new method could effectively overcome the bad influence of some factors such as model mismatch.

针对对象特性时变等不确定因素，该文以灰色多步误差预测校正替代原有算法的当前一步误差校正，可以更为有效的克服模型失配等因素的影响。

The synthesis of the pentacyclic skeleton of Et-743 and the construction of the five chiral centers thereof.1. The core pentacyclic skeleton of phthalascidin was constructed with L-dopa as the starting material via thirteen steps. First, two basic synthons, the C-1 functionalized tetrahydroisoquinoline compounds 8 and N-protected Z-dopa derivative 9, were prepared from L-dopa. They were coupled via amide bond to form the dipeptide compounds 10, which were the first key intermediates. Then the primary hydroxyl groups were transformed into the corresponding amino aldehydes 11 via Swern oxidation. Followed by the intramolecular Pictet-Spengler cyclization, the pentacyclic compounds 12 were synthesized.

五环骨架的构建及五个正确手性中心的确立：1.1我们以L-多巴为起始原料，经过多步官能团保护和转化合成了基本结构单元8然后和苯丙氨酸衍生物9，通过缩合反应生成酰胺中间体10，经Swern氧化得到醛化合物11，然后再次利用分子内改良的Pictet-Spengler反应一步构建c，d两环，得到五环骨架化合物12，最后，实现了21-位羰基向氰基的转化，得到了C-1位官能化的化合物14，化合物14不但具有和Et-743一致的五环骨架，而且分子中五个手性中心立体构型也与其完全相同：其中，3，位和13，位的手性中心由原料L-多巴带入，而1，位，11，位和21，位手性中心则通过不对称诱导而确立。

At first the definition of prediction values of system, network model, prediction model are given, then the stochastic approximation character of the system including simple system noise when identified by a network model using seriesparallel scheme is analyzed as well as the effect of noise on the model multi-step prediction is discussed.

首先对系统、网络模型、预报模型的各种预报值作了定义，然后针对只含简单系统噪声的系统讨论了在串-并联辨识方案下模型对系统一步预报的概率逼近特性，并分析了噪声对模型多步预报的影响。

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。
