The industrialization as a whole is underde- veloped,and developed slowly.

目前,我国农业高新技术产业化发展已取得了喜人的成绩,但与国外发这国家相比,还存在着很大的差距,我们的产业化整体水平还不是很高,发展速度缓慢。

But Germany,as one of the most important countries in Europe,whose democratic progress is very slow.

而作为欧洲大家庭的重要一员的德国,民主进程极其缓慢,魏玛共和国是德国民主化进程中所取得的阶段性成果,但存在15年后就被希特勒埋葬了。

However,housing loan has been developing slowly up to now.

随着经济的发展和人民生活水平的提高 ,住房消费成为城市居民的消费热点 ,为抓住这一契机 ,各家商业银行相继推出了个人住房贷款业务 ,但这一业务从推出到现在却发展缓慢。

The system parameters of the compound pendulum are calibrated in slow loading condition; and the maximal angle is measured in impact loading condition.

本文分析了编码器的基本特征,建立了一套以编码器为核心的复摆冲量测量系统,给出了编码器在冲量缓慢加载阶段复摆系统参数标定及冲击加载阶段最大摆角测量的应用结果。

In order to discuss the microstructure under slower cooling rate of as-cast AZ91D magnesium alloy,the slow solidification treatment was carried out.

为了探讨AZ91D镁合金在较慢凝固冷却速度下的组织,对其进行了缓慢凝固处理。

In this paper, AZ91D as-cast magnesium alloy was studied by OM, SEM, TEM ,XRD, EDS, which was treated by slow solidification, solution ageing and homogenizing annealing treatments.

为此,本文选择了具有代表性的AZ91D镁合金铸锭,对其进行缓慢凝固处理、固溶时效处理和均匀化退火处理,利用光学显微镜、扫描电子显微镜、透射电子显微镜等观察合金的显微组织,利用X射线衍射仪、X射线能谱仪定性和定量地分析合金及微区成分,并对合金的布氏硬度、微区的显微硬度及抗拉伸、抗压缩性能等进行测试,对合金凝固过程和脱溶析出过程进行分析,探讨这三种方法对消除偏析β相,改善二次β相的析出形态及力学性能的影响。
