There were no visible morphological change in water hyacinth exposed to a mixture of ethion , dicofol , fenvalerate , fenpropathrin , deltamethrin , and cyhalothrin with the concentrations of 0 . 01 mg / l , 0 . 1 mg / l , and 1 mg / l , but the fresh biomasses were increased by 49 . 79 % , 40 . 34 % , and 83 . 88 % respectively compared to those planted in water solutions without pesticides 植物在5mg kg三氯杀螨醇及50mg kg和5mg kg乐果的环境中生长良好。动力学研究结果表明，植物对有机农药的净化过程符合一级动力学反应。凤眼莲对水溶液中有机农药的净化效率很高。
When the key sets of rod inserted into the key hole - hyacinth , it promotes the key to the push and pull the slider , key sets of poles anti - shedding pellets and control of the key defense shedding hole match , it can completely avoid the improper operation of the satellite will be key to pulling it off or broken , it will greatly enhance the chain - like soft - key life 当钥匙套杆插入葫芦型钥匙孔内时，推动钥匙上的推拉滑块，让钥匙套杆上的防脱落珠与钥匙控内的防脱落孔相吻合，彻底避免了因操作不当而将钥匙拧断或拉断，大大提高了链节式软钥匙的使用寿命。
Somewhere she was tender , tender with a tenderness of the growing hyacinths , something that has gone out of the celluloid women of today . but he would protect her with his heart for a little while . for a little while , before the insentient iron world and the mammon of mechanized greed did them both in , her as well as him 她有点什么温柔的东西，象滋长着的温柔的玉簪花似的温柔的东西，这东西是今日化学晶的妇女们所没有的了，但是他定要诚恳地把她保护一些时日，只一些时日，直至无情的铁世界和机械化的贪婪世界把她和他自己同时压倒。
The removal dynamics of pesticides by plants was corresponded with the first order kinetic reaction . the half lives of dimethoate , malathion , and methyl parathion with a concentration of 10 mg / l , ethion , dicofol , and cyhalothrin with a concentration of 1 mg / l in 250 ml planted with 10 - 11 g water hyacinth were 236 hrs , 77 hrs , 25 hrs , 65 hrs , 62hrs , and 80 hrs , and those in unplanted water solutions were 338 hrs , 274 hrs , 226 hrs , 236 hrs , 114 hrs , and 365 hrs respectively 浓度分别为10mg l的乐果、马拉硫磷和甲基对硫磷及ling l乙硫磷、三氯杀螨醇和三氟氯氰菊酯250ml在104凤眼莲培养液中的半衰期为236hr 、 77br 、 25hr 、 65hr 、 62hr和80hr ，而无凤眼莲对照培养液中的半衰期分别为338hr 、 274hr 、 226hr 、 236hr 、 114hr和365hr ，其降解速率分别提高了43
