查询词典 H-hour

You would also need to come up with a method for estimating H.

你也需要选择一种估算H值的方法。

Chapter 7 gives the H-stability of the eqilibrium point set first (theorem7.1), and the other two theorems (theorem7.2-7.3) provide an estimation result for the attractive region of different eqilibrium points.

首先给出了非凸梯度神经网络平衡点集合的H—稳(来源：AB29e6C论文网www.abclunwen.com)定性结果(定理7.1)，另外的两个定理(定理7.2—7.3)给出了不同平稳点的吸引域估计。

Some factors affecting the etherification, such as temperature, time and catalysts etc, were studied, and the relatively optimal reaction conditions were worked out molar ratio of reaction material/catalyst 1/1, T=100, t=1 h.

研究了影响醚化反应的一些因素，如温度、时间、催化剂等，并在此研究基础上得出了较佳的醚反应条件为：物料／催化剂的摩尔比为1/1，温度为100℃，时间为1 h。

At higher reaction temperature, Ir particles abstracted H atom from the adsorbed ethoxyl species and formed stable five-membered oxametallacycle intermediate (Ir-CH2CH2OO-Ce4+), which was helpful to the disruption of C-C bond and the reforming of CHx group.

高温时，Ir可能从-CH3基团中提取H原子，形成了Ir-CH2CH2OO-Ce4+结构，从而更有利于碳碳键的断裂和CHx物种的重整反应，提高氢气的产率。

At lower temperature, the interaction between the Ir particles and the adsorbed ethoxyl species is not strong enough to abstract H atom from the nearby CH3 group, and thus acetaldehyde acts as the key intermediate. Acetaldehyde can decompose to methane and CO and/or convert to acetone through decarbonylation.

低温时Ir粒子与吸附的乙氧基的相互作用的强度不足以从-CH3基团中提取H原子，此时乙醛是关键的反应中间物，乙醛可以裂解生成甲烷和一氧化碳或脱羰基生成丙酮。

Euchromatin Network was created by John H. Frenster of USA. It is designed to help researchers and others interested in the latest developments in our studies of this most active part of the genome within the cell nucleus including Ultrastructural Probes of Active DNA Sites, and the RNA Activators of DNA.

该网络由美国人约翰·H·弗兰斯特创建，旨在为动植物染色质研究人员及对该领域感兴趣者提供有关细胞核中基因组研究的最新信息，包括激活位点的超级探针、DNA的RNA激活子。

Value.h completely hides the evaluator for arithmetic expressions and at the same time specifies what we have to implement.

识别器完成了。value.h完全隐藏了数学表达式的求值程式，同时也指定了我们必须要实现的函数。

Result The optimum exaction technology conditions were as follows: 60% ethanol, solid-liquid ratio of 1:20, soaking for 24 h and ultrasonic time of 30 min.

结果］最佳提取工艺为60%的乙醇，固液比1：20，浸泡24 h，超声时间30 min。

This research was conducted in degraded rangeland at the southwestern edge of the Mu Us sandland, Yanchi county, Ningxia, the soil seedbank features and its relation to vegetation was analyzed using similarity analysis and ordination method, the results show that seeds within soil distribute mainly in 0~5 cm soil layer, less seeds in 6~15 cm soil layer in exclosed and non-exclosed rangeland, for seeds in exclosed soil, species richness and diversity index H are higher, while D is lower, exclosure measure, generally speaking, can increase plant species and amount of vegetation and seeds in soil, some annual plants, mesophytes and halophytes appears in the soil or surface.

以毛乌素沙地西南缘宁夏盐池县的退化草场为研究对象，采用相似性分析和排序方法对封育和未封育草场土壤种子库的特征及其与地上植被间关系进行了研究，结果表明无论封育区还是未封育区，土壤种子库中的种子主要分布于0~5cm的土层，6~15cm土层的种子数很少；封育区土壤种子库的物种丰富度大于未封育区，物种多样性则表现为H 值较大，而D值较小，总体上看封育措施可以提高地上植被和土壤中种子的种类和数量，一些一年生植物、中生植物和盐生植物开始出现在地面或土壤种子库中。

Objective To investigate the change of 24 h absorption, distribution and excretion of brick-tea fluoride in rats.

目的 观察砖茶氟在大鼠体内24 h吸收、分布及排泄的动态变化。
