有保证的

This opening is for supplying fresh air for you to burn wood (even though some fireplace comes with built-in fresh air vents).

即使有些壁炉本身已经安装有能供应新鲜空气的风口，使用它们时最好也能打开门窗，以保证为壁炉燃烧木头时提供足够的新鲜空气。

While by introducing the spherical simplex UT, a better-behaved sigma point selection strategy, the number of sigma points required to the same transformation accuracy can be dramatically reduced, and accordingly, the computation burden can be avoided.

在有陀螺模式下，设计了基于误差修正罗德里格参数的SUKF姿态估计算法，在计算过程中同时能够保证四元数始终归一化。在无陀螺模式，基于MRPs的姿态表示和卫星刚体动力学方程，实现了SUKF姿态估计算法。

First of all, you need a really good rear brake -- you should have 100% braking power with just 1 finger.

首先你得有一副好的后刹----必须保证只用一个手指就能达到100%的刹车力。

In comparison with bugle shaped nozzle, bifurcated nozzle downward jet angle 45°, cow-nose nozzle and three-hole nozzle, in all, the last two are better than the former and bifurcated nozzle downward jet angle 45 is better than bugle shaped nozzle; Cow-nose nozzle is helpful for guaranteeing the product's quality, in order to protect jet flow from eroding the strand at narrow face, gain uniform temperature distribution at cross section and decrease heat flux, adding the block's width to 100 mm. Three-hole nozzle is advantageous to increase flux and casting speed, but should avoid weak shell thickness in the center broad. In the real production, setting the SEN's immersed depth or plugging the hole at the bottom can adjust the flow and temperature distribution in the mold.

对比喇叭形水口，双侧孔水口(45°)，牛鼻子水口和三孔水口，总的说来后两者优于前两者；而双侧孔水口(45°)又优于喇叭形水口；牛鼻子水口和三孔水口比较各有特点，前者对保证铸坯质量有利，为防止流股对窄面的冲击，增加挡块宽度到100 mm，可使结晶器横截面上温度分布更加均匀，降低窄面热负荷；后者对增加流量，提高拉速非常有利，但要防止中孔射流过强导致铸坯中心坯壳变薄，在实际生产中可通过控制水口浸入深度或塞住浸入式水口的底孔来调节结晶器中的流动与温度分布状态。

These may be antiquarians, annalists, naturalists; they may be learned in the law; they may be versed in statistics; they are most useful in their own place; I should shrink from speaking disrespectfully of them; still, there is nothing in such attainments to guarantee the absence of narrowness of mind.

这些人可能是古玩收藏家，编年史撰写者，博物学家。他们可能通晓法律，精通统计，他们是他们自己行业非常有用的人才。对他们有所不尊，我心里有怯；但是无法保证他们的思想不会流于狭隘。

It is critically important to keep Scorpions alive until you have access to Avatars.

直到你有权限造圣灵之前非常重要的是一定要保证蝎子的存活。

Avenir managing director Andy Tow added: Our clients may be familiar with the structure - guaranteed per connection payouts above target, weekly awards and a grand final award - but we hope they'll agree we've outdone ourselves with what's on offer.

&精工总经理安迪丝束说：&我们的客户可能是熟悉的结构-保证每个连接支付上述目标，每周奖和总决赛奖-但我们希望他们会同意我们已经超越自己，有什么问题提供。

Research on local scour during settling of steel caissons is an important topic for design and construction of large-scaled bridge piers.

钢沉井下沉过程中局部冲刷的研究是同类桥墩设计和施工十分关心的重要课题，它对保证钢沉井安全有效施工、桥梁设计中施工期桥墩最大冲深、失稳和安全计算有重要参考价值。
