对高水头、大单宽流量、低佛氏数、小底坡长明流泄洪洞，在反弧段末端采用常规的掺气坎往往难以取得理想的掺气效果，同时，反弧段下游边墙易出现空蚀破坏。

Considering the theory of roadway support in soft rock, we proposed an active support mode based on study of rheology of weak adjacent rock, complex stress environment, and destabilization of original supports. Fully grouted bolt, extension grouted cable that can strengthen self-bearing capacity and entirety are used. Original support scheme and reinforcement scheme are simulated by means of FLAC(superscript 3D).

在分析硐室围岩岩性、软弱围岩流变、复杂应力环境及原支护结构失稳的基础上，结合软岩巷道围岩控制理论，提出了以全长锚固锚杆、锚索增强围岩整体性和自承载能力的主动支护，并以底板锚注加底拱返修加固。

Substrate limited fed batch cultures were used to study the growth, metabolism and antibody production of HB 58 hybridoma cells.

对底物限制的流加培养中杂交瘤细胞HB58的生长、代谢和单抗生成进行了研究。

At present, the Kaplan plan leading by International Seabed Authority has allied multi-country scientists to study the deep-sea polymetallic nodule areas that include the projects of meiofauna variation and gene flow.

目前在国际海底管理局主导下的Kaplan计划，已联合多国的相关科学家对结核区深海包括小型底栖动物和基因流变化等环境项目展开调查和研究工作。

Tantalus was the rich and mighty king of lydia.son ofzeus by a fairy maiden,he was greatly favored by the gods.he was invited to share wine and food with them at their banquets,and he was let into their secrets .but ever the latter end of joy is woe .either because he had stolen wine orgave away the secrets of zeus,or because he had become so proud as to test the gods by serving up the flesh of his son pelopsto them,he incurred the wrath of zeus and was hurled down to the everlasting darkness of tartarus .there he was made tostand up to his chin in a little lake,with clusters of luscious fruits hanging over and around his head.he strove eternally to drink the ever-evading water and to clutch at the delicious fruits which were ever tossed out of his reach by blasts of wind.thus he was doomed to endure endless burning thirst and bitter hunger in the world of the shades.the whole occurrence has given rise to the expression"tantalizing",meaning somethng inplain view but unattainable .

坦塔罗斯是罗底亚富有而又强大的国王。他是宙斯和一位仙女的儿子，深受众神喜爱。众神请他参加宴会，与他们共享美酒与美食，并且还让他了解他们的秘密。然而乐极生悲。或许是他偷了美酒、或者泄露了宙斯的秘密、或许是他太骄傲以至于献上自己儿子珀罗普斯的肉来检验神的智慧，他招致了宙斯的愤怒，被打入了永远黑暗的地狱中。在那里他被迫站定于一小湖中，水没至下颌，无数甜美的水果悬于头顶和四周。他从不间歇地努力喝水，但水总是从嘴边流走；他试图抓住那些美味的水果，但总是被阵阵来风吹离，使他无法得到。因而他注定要在阴间遭受炙渴和难以忍受的饥饿。&tantalizing&一词即由此而来，意思是在眼前却无法得到的某个东西。
