Plane waves are absolutely stable against small modulations in self-defocusing media, the dark spatial solitons exist only in the form localized dark hole on the plane wave background.

在自散焦介质中，平面波的传播对小的调制扰动是绝对稳定的，暗空间孤子正是作为平面波背景上的一种局域暗迹而存在的。

SS-JM series colloid mill can accord to users' special requirement offer the one multi-functional but idling type operation. The machine is sealed and has not kept in touch with the medium definitely. Machinery seal can use longevity long of new generation hygiene grade and colloid rub (the patent for invention of China) and has developed another kind of closed colloid rub. Its all closed circulated backset current system makes the supplies carry on the multi-functional grind, emulsification, homogeneous, crush, disperse, and stir, processing that mix in the airtight environment.

SS-JM系列胶体磨擅长于可根据用户的特殊要求提供多功能的可空转式运作，机封与介质绝无接触，机械密封使用寿更长的新一代卫生级可空转式胶体磨，以及研制了另一种封闭式胶体磨其全封闭式内循环回流系统，使物料在密闭的环境中进行多功能研磨、乳化、均质、粉碎、分散、搅拌、混合的加工。

In a commercial nursery using the peat moss-plug system, these three strains also showed their ability to promote seedling growth following either seed bacterization or peat moss drenching, and their populations in peat moss maintained at high levels (except strain RS65 for 30 min seed soaking ) within 21 days after seeding. The above 14 strains that were capable of promoting tomato growth were tested for their ability to control bacterial wilt of tomato.

自台湾中部不同地区数种作物分离得到之396株根栖细菌，被覆於番茄种子后，利用套袋塑胶培养皿之系统及含泥炭土栽培介质之穴盘系统於生长箱筛选，共有 14株菌株在重复筛选过程中均能提高种子发芽率及促进根生长之效果，其中RS4、RS65及RS70三菌株表现最佳，可增加根长度、茎长度、植株鲜重及乾重(RS65菌株除外)。

By the use of a dielectric polarization theory this paper analyzes the field charging states of a ball-shaped and a cuboid shaped particulate placed in an electrical precipitator field.

用电介质极化理论对置于电除尘器电场中的球形粒子、长方体粒子的场荷电情况进行了分析，然后分别导出各自条件下的场荷电方程。

As we have learned, had arrived to make sure activated carbon puts in smoothly 25 days among filter, total fleet of Heilongjiang province armed police is close 1000 officers and soldiers from 24 days 17 when to 25 days of before dawn 4 when, day and night endlessly, many tons of 1000 in crossing 16 filter anthracitic filter expects all Qing Dynasty goes out. 10 when make 30 minutes, the reporter sees, as a result of excessive overworked, a lot of people in them were leaning on baluster to be asleep.

据了解，为了保证25日活性炭顺利投放到过滤池当中，黑龙江省武警总队近千名官兵从24日17时至25日凌晨4时，昼夜不休，将16个过滤池中的1000多吨无烟煤滤料(主要分为以进水过滤的粒状材料与物理分离的过滤介质两大类)全部清出。10时30分许，记者看到，由于过度劳累，他们中的很多人都倚着栏杆睡着了。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
