查询词典 difficult position

Deformation greatly promoted carbonitride isothermal precipitation and made C-curve shift leftwards. The position and shape of C-curve depended on the content of Nb and N to a great extent, C-curve shifted leftwards a little when N content increased and its nose temperature was raised with Nb content increased. 3 when cooling rate increased, start temperature and finish temperature of continuous cooling precipitation decreased, full precipitation became difficult to take place, the volume fraction of carbonitride precipitation decreased, molar fraction of Nb and C dissolved in austenite increased, and the precipitation grain was further refined. Deformation shorten precipitation start time during continuous cooling, raised precipitation start temperature, accelerated precipitation kinetics of carbonitrides.

计算表明：1在Fe—Nb—C系统中，随着温度的降低，析出相的平衡体积分数增加，溶解在奥氏体中的Nb、C的摩尔分数降低，析出相中C和Nb的原子分数的比值v增加；2变形大大促进了碳氮化物的等温析出，使C曲线左移，Nb和N的含量与C曲线的位置和形状有一定的关系，N含量的增加，使C曲线略有左移，而Nb的含量的增加使得C曲线的鼻子区上移；3随着冷却速率的增大，连续冷却析出的开始温度和结束温度均有所降低，并且析出变得越来越不充分，析出相体积分数明显减小，溶解在奥氏体中Nb和C的摩尔分数增大，析出相粒子被明显细化，变形大大缩短了CCP过程碳氮化物析出的开始时间，提高了析出的开始温度，促进了析出动力学。

Under certain trading conditions it may be difficult or impossible to liquidate a position.

Based on inverse equation, the forward solution model of position is presented in this thesis through method of successive approximation, for parallel robots possess characteristic of easy inverse solution and difficult direct solution. The method is proved to be highly effective by simulation example.

根据6-SPS并联机器人反解容易、正解较难的特点，本论文基于位置反解方程，通过杆长逐次逼近的思路建立了位置正解模型，并对该方法进行了实例验证。

It often happens that the parachute is too difficult, or even impossible, to extract from it's container (especially for less aggressive persons) because of too much Velcro, or deployment pins which are too long. In certain cases, if the pilot's in a spin, it's not even realistic to grab the handle of many parachute systems. After having mounted a parachute on a harness, it's vital to do a hang check to verify that the deployment handle is truly easy to grab and that the parachute can be pulled from the container with minimal effort and in any variety of pilots position and circumstances. Seems obvious, but almost no one actually does it!

而时常发生的情况是由于过多的尼龙搭扣，或者保险销过长导致备份伞很难，甚至是根本不可能从吊带里面抽出来（尤其是对于那些体力较差的飞行员）；在某些状况下，比如在螺旋当中，很多备份伞系统的备份伞手柄根本就不可能抓到；因此在安装好备份伞之后务必要做悬挂检查：将吊带吊起来，自己坐在上面模拟在各种飞行状态下是否能够轻易而迅速的抓住手柄将之抛出来；显然，没有多少人做过这个模拟。
