| 1. | " for his contributions to the theory of electron transfer reactions in chemical systems 创立和发展了电子转移反应理论 |
| 2. | The laboratory study on displacement efficiency with microbial and chemical system 微生物与化学剂体系结合提高驱油效率的实验研究 |
| 3. | Any of the minimum number of substances required to specify completely the composition of all phases of a chemical system 组分:任一能完全区分各种化学系统所有构成成分所必需的最少量物质。 |
| 4. | Because of the chemical system ' s complication and largeness , there are many influence factors of chemical engineering process . it is hardly to establish completely and strict mechanism model 由于系统趋于复杂化和大型化,化工过程的影响因素很多,难以建立全面的、严格的机理模型,为此,我们提出了先用神经网络建模,再用遗传算法求解的优化方法。 |
| 5. | The extension of the mechanical high pressure measuring instrument in the chemical system of units to a top measuring value of 10 kbar is the result of consistent further development of the successful high pressure instrument programme 凭借着我们在高压仪器项目中断深入研发,我们可向客户提供更广量程适用于单元化学系统机械式高压测量仪器,最高可达千巴 |
| 6. | As the chemical system was an open one , itself was constantly developed , changed and perfected . on the other hand , it constantly exchange its aterials , energy and message with other systems . therefore , the chemical knowledge has closely relationship with other subjects 化学系统本身是一个开放系统,一方面它本身不断地变化、发展、完善,另一方面它与其它系统之间不断地交换物质、能量、信息,因此化学知识系统与其它学科知识系统之间是相互联系、相互渗透的。 |
| 7. | Furthermore , the exergy analysis considered both the physical exergy and the chemical exergy were used to analyse the chemical synthesis and the power generation . the results when methanol synthesis ratio was 0 . 9 to the equilibrium state were compared with the separate electrical and chemical systems and showed that polygeneration was 3 . 5 % more efficient and less polluted 由于多联产系统耦合了化工和发电的过程,本文在采用火用分析的方法时,分别考虑了物理火用和化学火用,计算结果将联产和分产进行了比较,得出在甲醇合成产率达到0 . 9时,联产效率较分产高3 . 5 % 。 |
| 8. | The device of industrial automation based on the embedded chip technology has a deep developing space . today many embedded controllers have been applied in the fields of industrial process control , numerical control machine , electrical power system , electrical network safety , electrical network device monitor , chemical system 基于嵌入式芯片技术的工业自动化设备具有很大的发展空间,目前已经大量的嵌入式微处理器应用于工业过程控制、数控机床、电力系统、电网安全、电网设备检测、石油化工系统等领域。 |
| 9. | Due to its shortage in credibility , extensibility , and reusability , the traditional structure method in developing chemical system is hard to build a new model with exist ones . therefore , it is a developing trend using the object - oriented technology instead of the structure technology 传统的用结构化设计方法建立化工仿真系统,由于可靠性、可扩充性和可再用性较差,难以利用已有的模型产生新模型,因此,采用面向对象的方法取代原有的结构化方法开发计算机环境,已逐渐成为软件发展的趋势。 |
