查询词典 zero

The main purpose of this thesis is to research and develop three different kinds of battery chargers of resonant-switch converters. Starting with the zero voltage switch and the zero current switch converters, which employ the quasi-resonant converter technique, we gain the best parameters of the resonance components from the characteristic curve diagrams of these two converters. Then we design battery chargers based on these two structures and use them to experiment on lead-acid batteries.

中文摘要本论文之主要目的在於研制三种不同的共振开关式转换器蓄电池充电器，先探讨半共振式技术的零电压以及零电流转换器，利用这两种转换器的特性曲线图设计出共振元件最佳的参数值，以这两种架构作为蓄电池充电器，来对铅酸蓄电池做充电测试，经实验测得，零电压切换半共振式降压型转换器之充电器的开关在零电压的时候导通和截止。

It is not enough if we just only depend on static yield curve of zero-coupon bond which reflects the current term structure of interest rate and make it the lever for financial products with uncertain cash flow, especially the measurement of interest rate risk on financial products with random cash flow which is related to interest rate, but need to set yield curve of zero-coupon bond as dynamic models.

对非确定性现金流金融产品，特别是与利率相关的随机现金流的金融产品进行利率风险度量，单纯依赖反映现行利率期限结构的静态零息票债券收益率曲线作杠杆是不够的，而是需要把零息票债券收益率曲线建成动态模型。

Essentially, zero-coupon securities are bonds that have had their coupons stripped off: the broker removes the coupons and trades the remaining bond as a zero-coupon security.

从本质上来讲，零息债券是那种已没有息的券了。经纪人删除券及交易，其余的债券就是零息债券。

Zero-Coupon Securities In September, Berkshire issued $902.6 million principal amount of Zero-Coupon Convertible Subordinated Debentures, which are now listed on the New York Stock Exchange.

零息债券去年九月，伯克希尔发行了 9 亿美元的零息可转换次顺位债券，目前并已在纽约证券交易所挂牌交易，由所罗门公司负责本次的债券承销工作，提供了我们宝贵的建议与完美无缺的执行结果。

The pen would work under zero gravity conditions due to the pressurized ink inside, it would work under sub zero conditions, underwater, on glass and virtually any surface known to man.

Item (3) of Article 30, which provides:"In case the aerodrome elevation is comparatively high and if the pressure altimeter of an aircraft cannot be adjusted to the atmosphere pressure at the aerodrome elevation, the presumed zero altitude may be used", shall be revised as:"For an aerodrome that uses the atmosphere pressure at the aerodrome elevation, if the aerodrome elevation is comparatively high and where the pressure altimeter of an aircraft cannot be adjusted to the atmosphere pressure at the aerodrome elevation, the presumed zero altitude may be used".

Special morphisms such as monomorphisms, epimorphisms, sections, retractions, extremal monomorphisms, extremal epimorphisms, constant morphisms, coconstant morphisms, zero morphisms and special objects such as initial objects, terminal objects and zero objects are studied and their characterization is obtained.

较为系统地讨论了范畴Quant的性质，考察了范畴Quant中单态射、满态射、截节、收缩、极端单态射、极端满态射、常值态射、余常值态射、零态射等特殊态射和始对象、终对象等特殊对象，给出了它们的具体刻划，得到了范畴Quant是良幂的，余良幂点化范畴。
