JHF donated RMB10000 to bayinhua school towards the construction of a large green house used in the school 's training program for local farmers .

建华捐赠了10000元人民币给白音花学校，为学校给当地农民办的职业培训项目建大棚用。

The program ( CXS ) compiled by author has been applied to design rotary bury component of JHF 130 straw chopper .

编制的CXS程序软件在JHF－130秸秆粉碎掩埋机旋耕掩埋部件的设计中得到应用。

JHF has two representative offices in China ( in Tianjin and Xining ) and is in the process of registration with the Ministry of Civil Affairs under the new NGO law .

在中国内地，建华有两个代表处（分别在天津和西宁），目前正在新的基金会管理条例下重新在民政部办理登记注册。

The influence of JH and JHF on the viscosity and gel time of the resin in RTM as well as the volume resistivity and flexural properties of FRP are studied .

本文研究了JHF和JH型抗静电剂对RTM专用树脂粘度、凝胶时间及RTM成型FRP制品的体积电阻率和弯曲性能的影响。

The results indicate that the flame-retardant and antistatic properties can simultaneously meet the corresponding national standards when JH and JHF are added up to the 1wt % and 3wt % , respectively .

当JH型和JHF型抗静电剂添加量分别为1wt%和3wt%时，FRP的抗静电、阻燃性能能够同时达到相关标准。但是，抗静电剂的加入进一步降低了该材料的弯曲性能。

Computer programmes are worked out in this paper . Using the programmes , the critical rotation rate of chopping drum of field straw chopper JH - 100 * IHF - 150 , JHF - 130 are calculated particularly and main factors , influencing critical rotation rate are analysed .
