查询词典 duration

The method of measuring interest rate risk including duration,modified duration and convexity,is investigated.

文章对目前广泛应用的利率风险度量方法包括久期、修正久期和凸度进行了深入分析。

The explanation is quite simple. The duration of the fixed-rate coupon bond is the weighted average of the duration of the floater and inverse floater.

原因很简单，固定息票率债券的存续期是浮动利率证券的存续期和逆向浮动利率证券的存续期的加权平均数。

There seem to be certain cross action between infection duration and co-culture duration.

感染时间和共培养时间之间似乎存在一定的交互作用。

It is major work to present the tectonic time duration system of the strain rate method, which is an original exploration.(1) Principle: Its basis is the stress and strain rule depending on strain capacity in steady-state stress field, but not the radioactive decay law depending on radiation dose in invariable radiation field. This can be simplified as a process of differential stress-strain rate-strain capacity-time duration calculating.

工作重点是梳理出应变速率法构造时限定年系统，属原创性探索：①原理：不是基于放射性核素衰变规律，而是基于应力应变规律；不取决于恒定辐射场的辐射剂量，而取决于稳态应变场的应变量，可简括为差异应力-应变速率-应变值量-计算时限的求索过程。

Theywere temperature sensitivity,physiological vernalization requirement,photoperiodsensitivity,intrinsic earliness and filling duration(growing degree-day),reflecting thegenetic characters of different cultivars in thermal effectiveness,vernalization,photoperiod response,minimum flowering time and filling duration.

阶段发育模型引入温度敏感性、生理春化时间、光周期敏感性、基本早熟性和灌浆持续期五个遗传参数，分别体现了不同品种小麦在热效应、春化作用、光周期反应、最早开花时间以及灌浆期长短这五个方面的遗传特性。

Lock Duration 13.3.1.2 锁的持续时间 125 All locks acquired by statements within a transaction are held for the duration of the transaction, preventing destructive interference including dirty reads, lost updates, and destructive DDL operations from concurrent transactions.

事务内各语句获得的锁在事务执行期内有效，以防止事务间破坏性的相互干扰，例如：脏读取，无效地更新，以及其他并发事务中具有破坏性的 DDL 操作。

The discrete choice of parking location and the continuous choice of parking duration take place at the same time and are influenced by many common variables. Therefore, treating parking duration as an exogenous variable in parking location choice model would result in inconsistent estimates.

其中包含了间断性选择与连续性选择，此二选择决策系同时发生，且受到许多共同变数的影响，视停车延时为停车区位选择的外生变数，将使得模式校估所得的参数值产生偏误。

The experimental results show: the flattop phenomenon on the diode voltage pulse was very apparent for using the carbon fiber cathode, that is to say, the pulse duration of the diode voltage was widened; moreover, under the condition of the same power of microwave, the pulse duration of the out-put microwave was prolonged by about 30%; the peak power of the microwave was enhanced by 3dB.

通过在装置上做的两种阴极的对比实验，结果显示：碳纤维阴极的使用，改善了电子束质量，使辐射微波的脉宽增加了30%以上，辐射主瓣方向上的功率密度提高了3dB以上，频谱分布较纯净，实现了微波的高效输出。

Hence, the duration of the inverse floater exceeds the duration of the underlying fixed-rate bond.

因此，逆向浮动利率证券的存续期就大于其基础的固定利率债券的存续期。

Results from whole-cell patch clamp showed: 1 BmK Ⅰ(α-like neurotoxin) was found to prolong the duration of action potential and promote the amplitude of action potential. The effects could be attributed to the selective action of BmK Ⅰ on the TTX-S Na〓 channel: slowing the inactivation process of Na〓 channel, increasing the amplitude of peak Na〓 currents; 2 BmK abT, a new-type neurotoxin with higher sequence homology to β-type scorpion neurotoxin, was found to slow the inactivation process of Na〓 channel and prolong the duration of action potential in DRG neurons.

全细胞膜片钳研究发现：1）类α型哺乳动物毒素BmK Ⅰ可延长部分DRG神经元全细胞动作电位的时程，增加动作电位的幅度，这些效应可归咎于BmK Ⅰ选择性地作用于DRG神经元TTX—S钠通道，延缓TTX—S钠电流的失活化相，峰钠电流幅度增加；2）BmK abT，一个与β型毒素同源性较高的新型蝎毒素可抑制DRG神经元全细胞钠电流失活化过程，使动作电位时程增加。
