The primary forms of interest rate risk to which banks are typically exposed are:(1) repricing risk, which arises from timing differences in the maturity and repricing of bank assets, liabilities and off-balance sheet positions;(2) yield curve risk , which arises from changes in the slope and shape of the yield curve;(3) basis risk, which arises from imperfect correlation in the adjustment of the rates earned and paid on different instruments with otherwise similar repricing characteristics; and (4) optionality, which arises from the expressed or implied options imbedded in many bank assets, liabilities and off-balance sheet portfolios.

银行面对的利率风险主要表现为以下几种形式：（1）再定价风险，它产生于银行资产、负债和表外业务的期限不匹配和利率调整的幅度不一致；（2）收益曲线风险，它产生于收益曲线的斜率和形状发生的变化；（3）基本点风险，与再定价风险相似，它主要来自对不同金融工具收取和支付的利率不成比率的变动；（4）选择权，它产生于银行资产、负债、表外业务中存在的或明或暗的选择权。

I was now recover'd from my Surprize, and began to look round me, when I found the Cave was but very small, that is to say, it might be about twelve Foot over, but in no manner of Shape, either round or square, no Hands having ever been employ'd in making it, but those of meer Nature: I observ'd also, that there was a Place at the farther Side of it, that went in farther, but was so low, that it requir'd me to creep upon my Hands and Knees to go into it, and whither I went I knew not; so having no Candle, I gave it over for some Time; but resolv'd to come again the next Day, provided with Candles, and a Tinder-box, which I had made of the Lock of one of the Muskets, with some wild-fire in the Pan.

这时，我从惊恐中恢复过来，开始察看周围的情况。我发现洞不太大，周围不过十二英尺，但这完全是一个天然的洞穴，既不方，也不圆，不成什么形状，没有任何人工斧凿的痕迹。我又发现，在洞的尽头，还有一个更深的地方，但很低，只能俯下身子爬进去。至于这洞通向何处，我当然不得而知。当时我手头没有蜡烛，只好暂时不进去，但我决定第二天带上蜡烛和火绒盒进去。那火绒盒我是用一支短枪上的枪机做成的。另外，我还得带一盘火种。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
