In addition, all these core modules conformably used the ACE interface while using thread operations, UDP communication, timer and other APIs closely related to the operating system, which improved the portability of code and solved the problem of cross-platform development of distributed system. Reliability guarantee layer and resource management module completed object-oriented interface design by using OMG's IDL language, which ensured the openness of the distributed system.
另外，所有核心模块在使用到线程操作、UDP通信和定时器等与操作系统密切相关的API时，统一使用了ACE的接口，提高了代码的可移植性，解决了分布式系统的跨平台开发问题；可靠性保证层和资源管理模块使用OMG的IDL语言完成面向对象的接口设计，保证了分布式系统的开放性。
The biotranformation of ginsenosides Rh〓 and Re afforded compounds xyz11 and sywz22 which was linked with one more glucosyl moiety compared with the substrates, respectively. The transformation of ginsenoside Rh〓 to xyz11 was repeated by the incubation of UDP-glucose with the cell-free extracts of B.
对人参皂苷Rh〓和Re的转化产物进行了分离和结构鉴定，得到两个新化合物XYZ11和SYWZ22，与原底物比较，他们都是在底物上增加了一个葡萄糖基，Rh〓用菌体的粗酶提取物进行反应也实现了同样的生物转化。
UDP is a connectionless protocol and, as such, it can be easily spoofed.

When possible, administrators should use the ip helper-address command to relay broadcast requests for these key UDP services.
因此如果可能的话，所有的管理人员将会选择使用ip helper-address的命令，将重要的UTP服务的广播要求从路由器转送出去。
To solve the real-time and non-determinism problems, this article introduces a switched CSMA/CD- Master/slave hybrid protocol on Ethernet bus used for control applications.
针对控制应用实时性和确定性要求，提出一种面向控制应用的总线以太网CSMA/ CD- Master/ Slave切换混合协议，并在其上构建了UDP/ IP协议。
This is unnecessary if the underlying protocol provides a packet length as in UDP.
这是不必要的如果底层协议提供封包长度，比如UDP
By default, statistics are shown for TCP, UDP and IP; the -p option may be used to specify a subset of the default.
