The sharpest angles are usually seen on the frontal glacis plate, both as it is the hull side most likely to be hit and because there is more room to slope in the longitudinal direction of a vehicle.

现今的轻装车辆都配备金属网片，也就是所谓的「横条护甲」，而一些主战坦克也会携带橡胶侧裙来保护它们相对脆弱的悬吊机件或前方下侧的装甲。

Stainless steel hopper, mounted on a turret valve with spring lock pin and with the following three positions: fully closed, fully open and discharge through a pipe at the front of the extruder.

不锈钢料斗下方有一个带弹簧锁拴的塔式筏，它共有三种状态：全关、全开、通过挤出机前方的管道快速下料。

Methods: The shape and formation of superior lumbar triangle were observed from the external surface of posterior abdominal wall. The grouping patterns and courses of subcostal nerve, iliohypogastric nerve and ilioinguinal nerve passing the front of superior lumbar triangle were also observed.

从腹后壁外面观察腰上三角的形态及构成，由其内面观察经过该三角前方的肋下神经、髂腹下神经和髂腹股沟神经的组合形式及走行，并分别测量其与第12肋下缘的距离。

The recoery rate was calculated as follows;(JOA score at follow up_preoperatie JOA score)/(17 _ preoperatie JOA score) _ 100,15 and the surgical outcomes were classified into four grades based on the calculated recoery rate; excellent: recoery rate 75% or higher, good: 50–75%, fair: 25–50%, and poor: lower than 25%. Ealuation was made on radiographic findings, including the range of motion and the jaw diameter (a measured line from the posteroinferior corner of the ertebral body to the anterior aspect of the subjacent lamina) at the adjacent leels in group A and the affected leels in group B and the spinal canal diameter at the C4 leel in both groups. The C4 leel was chosen for this measurement, because the spinal canal is usually narrowest at this leel.

恢复率如下计算；（随访JOA评分-术前JOA评分）/（17-术前JOA评分）*10015，按计算的恢复率将手术结果分4级；优：恢复率75%或更高，良：50-70%，中：25-50%，差：低于25%。X线片结果评价，包括活动范围和颌直径（从椎体下后角到下邻椎板前方的测量线）在A组相邻水平与B组受影响水平及两组C4水平椎管直径。C4作为该侧量的选择是因为通常在此平面椎管最为狭窄。

Vertebral column were excided through dorsal meso-incision. the removed vertebral column were put on ice as soon as possible and L1/2, L2/3, L3/4, L4/5, L5/6 intervertebral disc tissue were procured.

取下整个腰椎段脊柱迅速放在冰面上，用眼科剪刀、镊剥离椎间小关节和椎体前方的软组织，分别从L1椎体下缘和L2椎体上缘分离上、下软骨终板，取出L1/2椎间盘组织。

The M249 is gas-operated and air-cooled. It has a quick-change barrel, allowing the gunner to rapidly replace an overheated or jammed barrel. A folding bipod is attached near the front of the gun, though a M192 LGM tripod is also available. It can be fed from both linked ammunition and STANAG magazines, like those used in the M16 and M4. This allows the SAW gunner to use rifleman's magazines as an emergency source of ammunition in the event that he runs out of linked rounds. However, this will often cause malfunctions because the magazine spring has difficulty feeding rounds quickly enough to match the SAW's high cyclic rate.

M249采用气动、风冷原理，枪管可快速更换令机枪手在枪管故障或过热时无须浪费时间修理，机枪下前方装有折叠式两脚架，也可使用M192轻机枪的三脚架。M249采用弹链及STANAG弹匣双重供弹，机枪手在断链缺乏弹药等紧急情况时可向装备M16或M4步枪的步兵借用弹匣来射击，但以弹匣供弹时会因弹匣弹簧弹力太大而射速过高及可能出现故障。

Landing a 7lb Redfish -- again a perfect head on shot at 12 o'clock with the fish tailing away from the boat so had to land the fly in front of it without spooking it.

钓上了7lb红大马哈鱼--再一次完善地向在船头前方的抛投，在跟着它远离小船的同时，毛钩必须在它前面落下，无需惊吓它。

The distances between inferior margin of 12th rib and the 3 above-mentioned nerves were all measured. Results: The superior lumbar triangle was quadrilateral (55%), triangular (35%) or irregular (5%). If the 12th rib was too short, the upper border of the triangle would be the 11th rib (5%). Four grouping patterns of the 3 nerves were found in front of the triangle, and the average distance between inferior margin of 12th rib and the 3 nerves was (16.92±6.32)mm,(59.49±14.97)mm and (112.49±17.15)mm, respectively.

结果：腰上三角的形态可为四边形(55%)、三角形(35%)和不规则形(10%)，该三角的上界可完全由第11肋(5%)构成；肋下神经、髂腹下神经和髂腹股沟神在腰上三角前方有4种不同的组合形式，三神经与第12肋下缘的平均距离分别为(16.92±6.32)mm、(59.49±14.97)mm、(112.49±17.15)mm。

Just then he saw a man-of-war bird with his long black wings circling in the sky ahead of him. He made a quick drop, slanting down on his back-swept wings, and then circled again.

就在这个时候，他看见一只军舰鸟，展开那长长的黑色翅膀，在他前方的天空中盘旋，突然之间，它将翅膀向后一收，倾身直往下伏冲，然后又开始盘旋。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
