However, the sparsity of the observational points used in the refraction method due to the restrictions imposed by the surface hypsography of the area-- one point per kilometre-- makes it possible only to give relatively accurate data for base rock velocities, but not for morphologic structure configurations.

但是，小折射方法受地表的地形起伏因素影响比较大，且观测密度也不够，每公里只有一个点，所以在该区只能较准确地给出基岩的速度信息，而无法准确地获得基岩的形态起伏数据。

However, owing to the much restricted hypsography of the surface for the refraction method and the insufficient surveying points --only one observational point a kilometre, we can only provide relatively true velocities of the base rock, but cannot obtain the accurate data of the morphologic-structural configuration.

但是，小折射方法受地表的地形起伏因素影响比较大，且观测密度也不够，每公里只有一个点，所以在该区只能较准确地给出基岩的速度信息，而无法准确地获得基岩的形态起伏数据。

When the hypsometer is used with static level gages, which are installed on the top and base of the dam, the altitude data transmission can be realized in real time.

若将传高仪与坝顶布设的静力水准仪和廊道内布设的静力水准仪相结合应用，则可达到实时自动传递高程的效果。

Auto-configuration and management of the system node on the base of communication has been implemented in the subject. On one hand, self-management of the system has been figured out. Not only variety in I/O ports but in bus nodes or modules, as long as keeping the data in the system configuration database in accordance with the physical conjunction, the software and hardware of the system need not to be calibrated by the operators.

本课题在实现通讯的基础上，实现了对系统节点的自动配置和管理，一方面实现了系统的自我管理，无论是IO点的变化还是总线节点、模块的变化，只要保持系统配置数据库中的数据与物理连接相一致，系统的软、硬件无需人为改动。

Methods of recording and mapping of ichnography of engineering geology and methods of making the vector and computer mapping of various initial data surveyed in different ways are introduced,horizontal base level of rock being taken as an example.

文中以岩质水平建基面为例，介绍了工程地质平面图图幅的编录测绘成图方法和利用不同方法测绘的各类初始数据进行矢量化计算机成图的方法。

In Chapter two, it was discussed the missing value imputation and the outliers detection which are the base work of data reduction.

数据归约两项重要的基础工作--缺失值填补和异常值探测是第二章探讨的内容。

If the defining query of a view is not explicit about which columns are referenced, for example, SELECT * FROM table , then the defining query is expanded when stored in the data dictionary to include all columns in the referenced base table at that time.

如果视图的定义查询中没有显式地说明引用哪些列，例如使用了 SELECT * FROM table 语句，那么 Oracle 在存储此定义查询时将引用基表中的全部列。

The conditions of low analysis phosphorous fertilizer＇ s manufacture, use and resources utilization were studied base on the inquisitional and statistical data.

传统的低浓度磷肥的产量从2000年的428万吨P2O5到2004年的468万吨P2O5基本稳定的情况下，在磷肥总产量中的比重从64.6%下降到46.0%。

The conditions of low analysis phosphorous fertilizer's manufacture, use and resources utilization were studied base on the inquisitional and statistical data. It shows that the inconsistency between the steady outputs of low analysis phosphorous fertilizer and the rapid demand of all kinds of nutrient for agricultural production can increase the market room of low analysis phosphorous fertilizer. It also indicates that the inconsistency between the phosphate demand of low analysis phosphorous fertilizer and the usability of phosphate rock can bring great development in future.

基于农户调查和统计数据，对我国低浓度磷肥的生产分布状况、使用状况、资源利用状况的分析表明，低浓度磷肥产量的徘徊不前与农业生产对中量元素需求增加的矛盾将拓展低浓度磷肥的市场空间；生产低浓度磷肥适用的磷矿品位与我国磷矿资源条件的吻合，使低浓度磷肥在未来有很大的发展空间。

Oracle uses integrity constraints to prevent invalid data entry into the base tables of the database.

Oracle 使用完整性约束防止用户向数据库的基表中插入无效数据。
