A method of drop hammer impact sensitivity test for big-bill explosive was developed.

设计建立了一种炸药大药片撞击感度试验方法，落锤质量为20 kg、落高度为0~15 m，对规格20 mm×5 mm、重约2.8 g的大药片进行撞击感度测试。

The genetic analysis was carried out for 8 characters on 9 energy cane parents and their 20 combination crosses with the NCII mating design. The results showed that the inheritance of stalk biomass, brix weight, available stalk numbers and weight per stalk was subject to both additive gene effect and non-additive genes effect, but mainly controlled by non-additive genes. The inheritance of plant height, stalk diameter and brix was subject to both additive gene effect. The broad sense heritability (HB2) of stalk biomass and brix was over 50%, and those of brix weight were 33.7% at the seedling stage 54.4% at its ratooning stage, respectively , which means that the selection would be done better at the early stage in the sugarcane breeding program.

利用遗传交配设计对能源甘蔗9个亲本组配的20个组合、8个性状进行遗传分析，结果表明：地上部鲜重、锤重、丛有效茎数和丛重的遗传既受基因的加性效应也受基因的非加性效应所控制，但以非加性效应为主；株高、茎径和锤度的遗传主要是受基因的加性效应控制，地上部鲜重和锤度实生苗新植和宿根的H_B~2都在50％以上，而锤重的H_B~2分别为33.7％和54.4％，而且锤重和地上部鲜重母本gca方差都大于父本gca方差，说明能源甘蔗育种中母本选择的重要性。

Hydraulic hammer model in the figure, you may re-express or bucket excavator machine capacity, but also may indicate that the weight of hydraulic hammer, or drill rod diameter, or hydraulic hammer impact energy.

液压锤型号中的数字，可能表示挖掘机机重或斗容，也可能表示液压锤重量，或钎杆直径，或液压锤冲击能。

Suber-water pumps heavy hammer safety valve lever occurred. 1769 butterfly emerged.

电动闸阀1681年出现了杠杆重锤式安全阀。1769年出现了蝶阀。

There is the use of heavy hammer, as set by self-operated pressure control valve.

另有一种采用重锤作为设定的自力式压力控制阀。

History gives no single person credit for the key invention that made these clocks possible: a mechanism called the verge escapement that uses a notched wheel powered by a weight or a pendulum and checked by a set of teeth.

具体的发明人已经不可考证。它叫边缘擒纵机构。它由重锤或者钟摆驱动一个有刻度的轮子，轮子上有齿和刻度一一对应。

The bell weighs 13.8 tonnes , with a striking hammer weighing 203.2kg.

大笨钟重13.8吨，摆锤重203.2公斤，钟声间间隔为5秒钟。

The instrument includes a weight suspended in a spring connected to a registering needle which notes the vibration on a strip of celluloid.

这种仪器有一个重锤悬在与记录针联接的弹簧下面。记录针在一条电影胶片上记录振动。

The lever-type safety valve to prevent the heavy hammer to have their own mobile devices and limit leverage Pilot-Operated Safety Relief Valve deviant lead frame, spring-loaded safety valve should be to enhance grip and to prevent casual screw adjustment screw moving device.

杠杆式安全阀要有防止重锤自行移动的装置和限制杠杆越轨的导架，弹簧式安全阀要有提升手把和防止随便拧动调整螺钉的装置。
