查询词典 ejection

Let the impact loads be transformed into simulated dynamic loads by the use of dynamic load coefficient ,taking this as a foundation the structural optimization mathematical model of ejection seat was established by applying the variable density method.

运用动载系数将冲击载荷转化为拟动态载荷，在此基础上用变密度法建立了弹射座椅结构优化数学模型，提出了冲击载荷作用下弹射座椅的结构优化设计方法，并进行结构优化设计实例计算，得到了能够满足冲击力作用的优化结构。

This is necessary, as the pulverized propellant, which is used as the ejection charge, does not ignite readily, as black powder does.

这是有必要的，作为煤粉推进剂，这是用来作为弹射负责，不容易点燃，黑色粉末是否。

Nevertheless, the forward ejection concept was not forgotten, and in around 2003 Kel-tec initiated development of an accurate, semi-automatic rifle with long barrel and compact bullpup layout.

然而，向前弹出的概念没有忘记，在2003年左右凯尔，过渡时期发起了一个准确的发展，半自动步枪长桶和紧凑型小斗犬布局。

It must be noted that at the present time the only fully ambidextrous bullpup rifle with forward ejection is the Belgian FN F2000 assault rifle and its civilian derivative FS2000 , both available only in 5,56mm /.223 caliber.

必须指出，在目前唯一完全灵巧向前弹出小斗犬与步枪是比利时的新生力量F2000突击步枪及其文职衍生 FS2000，都只有在5，56毫米/ 0.223口径可用。

Despite the bullpup design, ejection is possible only to the right side, so firing from the left shoulder is seems to be impossible or art least dangerous for the shooter. Type 05 submachine guns are fitted with open sights and with proprietary scope mounts at the top of carrying handle; JS submachine guns have no open sights and fitted with Picatinny rail at the top of the receiver which can accept various types of sighting equipment.

尽管小斗犬的设计，才有可能排出的右侧，因此，从左肩射击的说法，似乎是不可能的，艺术最危险的射手。05型冲锋枪装有开放的景点和具有自主范围的顶部支架携带处理； JS冲锋枪没有开放的景点和与皮卡汀尼在接收器，可以接受各种设备发现铁路上方安装。

Through the computer simulation,analyzing the effects of pitch angle,roll angle,roll angle rate,sink rate,angle of attack and side angle on the track of ejection and save life height .

为提供弹射座椅多模态控制输入参数选择的理论依据，通过计算机仿真，比较分析了俯仰角、滚转角、滚转角速度、下沉率、迎角、侧滑角等弹射启动时飞机状态参数对弹射轨迹和安全救生高度的影响。

But Pemba's short-order ejection is a rarity .

但是Pemba这种快速驱逐是罕见的。

According to our present broadcasting situation,the thesis proposes using new technology to update and reform the present HFC. It also suggests broadcasting using self-advantage and arranging EPON in order to win the supermarket.

论文从我国广电的现状出发，结合实际，积极倡导采用新技术更新、改造我国现有的HFC网络；倡导广电现阶段利用自身优势，部署EPON网络来赢取市场。

A new general kinetic equation was derived in which the effect of the removal of condensation water was taken into account completely, and was applied to the polyesterification kinetic study of AA/HPHP and AA/NPG. It was found that the reaction order of self-catalyzed polyesterification was not constant. For these polyesterifications, the reaction order was 2.5 at a low temperature, while 3.0 at a high temperature.

考虑缩合水的排除对反应体系的影响，用体积浓度单位推导出一个新的聚酯反应总包动力学方程，并应用到AA/HPHP和AA/NPG两个聚酯化反应的动力学研究中，研究发现，自催化聚酯反应的反应级数并不是固定值，对于AA/HPHP和AA/NPG两个聚酯化反应而言，低温时反应级数为2.5，高温时反应级数为3.0。
