降低速度

In real accidents one drops at relatively low speeds, often less than 10 m/s, because the broken hang glider or collapsed paraglider greatly slow the descent. Rapid deployment of an emergency parachute is indispensable especially for these low speeds.

在实际的事故当中，通常都是飞行员以一个相对较低的速度下坠，通常是低于10米每秒，这是因为坏掉的三角翼或者已经塌陷的主伞大大降低了下坠速度，所以备份伞必须要在这种低速情况下有效迅速的打开。

A kind of more effective viscosifier can improve the viscosity of acid solution, reducing the mass transfer velocity of hydronium H+ towards the rocks surface, thereby decrease the filtrate loss of acid solution and the reaction rate between acid and salt, lengthen the distance of acid penetration.

向酸液中加入良好的稠化剂能提高酸液粘度，降低氢离子向岩石壁面的传质速度，因而降低酸液滤失和酸盐反应速率，增加了酸液的有效作用距离，提高了酸化效果。

Vacuum was satisfied to the requirement of fresh-cut taro package and benefit to reduce water loss and to inhibit browning. The treatment of insufflate fresh-cut broccoli with 20mg·L-1 6-BA could delay chlorophyll reduction, inhibit ion leakage increasing and slow down the process of senescence. Fresh-cut broccoli packed with the atmosphere combination of 2.5%O2+7%CO2+90.5%N2 had high Vc and high chlorophyll content, and the senescence of the products was delayed certainly. The gas mixture of 5%O2+ 2%CO2+93%N2 could reduce the rate of respiration, chlorophyll decomposition, membrane breakdown and tissue senescence of pakchoi.

真空包装适合鲜切芋头，降低贮藏中鲜切芋头的水分损失，抑制鲜切芋头褐变发生；用20mg·L~(-1)6-BA喷洒鲜切青花菜可推迟叶绿素降解，抑制相对电导率的增加，延缓了衰老；2.5％O_2+7％CO_2+90.5％N_2MAP包装的鲜切青花菜Vc含量较高，叶绿素荧光值也较大，明显延缓了鲜切青花菜的衰老：5％O_2+2％CO_2+93％N_2混合气体抑制了青菜的呼吸作用，降低了叶绿素降解速度，减缓了细胞膜损伤及组织衰老程度。

Based on natural gas state equation and dynamic theory of natural gas migration, natural gas velocity of flow rate equation before and after temperature and pressure decreasing is fetched, and with which interface natural gas lengths in different reservoirs are calculated and the changing law of equivalent-length natural gas in migration is analyzed, whence it is discovered that migrating velocity of natural gas along tilting up reservoir is increasing inch by inch, along with temperature and pressure continuously decreasing.

由此发现，在运载层物性不变的情况下，天然气沿上倾地层向上倾方向运移的过程，是随地层温度和压力不断降低、其运移速度逐渐增大的过程，如果有后续气体的加入，会使气体长度增大，致使运移速度增加得更快。

为了阻止或降低磁黄铁矿的自然风化反应速度从而达到源头治理酸性矿山废水的目的，首先必须研究它在各种条件下的氧化机理、氧化产物和氧化速度。

Through the analysis of the experimental and numerical calculation values, hereinafter gives the description of the characteristics of the flow and heat transfer within the rotating blade cavity. Influenced by the inflow structure and the centrifugal force, the air flow rate on the top of the blade is bigger than that at the bottom, therefore, there exists radial component velocity which may make the buoyancy force weaken the heat transfer behavior of the blade.

通过实验和数值计算的结果的分析，发现气流在旋转叶片腔内的一些流动和换热特征：在进口流动结构影响和离心力的作用下，使得叶片顶部的气流流量大于底部的流量，因此流体存在径向分速度，可能是这种径向分速度造成浮升力对叶片的换热起降低的作用。
