The principles structure types and developments of saw sensors are introduced as well as applications in physical and chemical area 介绍了saw传感器的基本原理、主要结构类型和国内外的发展状况,并阐述了saw传感器在物理和化学领域中的应用。
A variable of a structure type contains the structure s data , rather than containing a reference to the data as a class type does 结构是“值类型” ,而类是“引用类型” 。结构类型的变量包含此结构的数据,而不是像类类型那样包含对数据的引用。
There is a close relationship between two data structure types . in this case , one of the two often maintains a pointer initialized to the address of the second one 二种数据结构类型之间有紧密的关系。在这情况,其中一个经常会维持一个指针到第二个类型的住址去设定初值。
The study shows that the products of quasicrystal materials mainly consists of a - ( ti , zr ) solid - solution , i - phase , and c14 - laves phase with the mgzn2 structure type 通过研究我们发现合成产物主要是由准晶i -相、 ( ti zr )固熔体相及具有mgzn2晶体结构的laves相所组成。
According to different structure types this paper reviews the progress of all kinds of organocatalyst in catalytic feature , mechanism and application to asymmetric synthesis 摘要根据不同结构类型综述了近几年来各种有机催化剂的特点、机理及其在不对称合成中的应用研究进展。
Since the end of 1990s , spatial truss structure of concrete filled steel tube , which is new structure type for bridge , has been applied gradually in bridge engineering 自上世纪90年代末以来,钢管混凝土空间桁架结构作为一种新的桥梁结构型式,正逐渐在桥梁工程中得到应用。
In the paper , the structure type of torpedo turbine engine and the three - speed system states of work gas were researched . the work process of torpedo turbine engine was analyzed 本文对鱼雷涡轮机结构类型、鱼雷涡轮机的三速制工况进行了计算研究,对涡轮发动机的工作过程进行了分析。
Relational databases can represent nested data structures by using structured types or tables with foreign keys but it is difficult to search these structures for objects at an unknown depth of nesting 关系数据库可以通过使用结构化类型或带有外键的表,表示嵌套数据结构,但要为不知道其嵌套深度的对象搜索该结构是很困难的。
There are two lining structure types which are frequently used in engineering presently , one is the reinforced concrete lining , another is the steel lining encircled by concrete 摘要目前工程上比较常用的水电站调压井衬砌结构型式有两种,一种结构型式是钢筋混凝土衬砌结构型式,另一种结构型式是钢衬加回填混凝土衬砌结构型式。
It ' s also difficult to prepare magnetic polymer film using structure type polymers due . a new generation film is available which is called organic - inorganic nanostructure magnetic composite film 一方面,传统的无机磁粉-聚合物膜难以具备高性能;另一方面,由于合成的困难性,直接利用结构型高分子制备磁性聚合物膜现阶段还难以实现。
