On the basis of previously research, this paper re-probe into the mechanism of electro-chemist mechanical manufacturing process, making the rational technological parameter, and developing the manufacturing equipment. Through a lot of technology tests, get a lot of labratory data, accordingly, researched the surface feature of the electro-chemist manufacturing process, and deeply discussed its influence on the work piece feature. The last result is that: the electro-chemist mechanical manufacturing process can reduce the low-frequency component significantly, but on high-frequency component, it has little influence, having obviously positive pole flat effect. After manufacture, the tip parts on the surface of the work piece is cut off, there is micro "high land" shape, the parameter for surface roughness is reduced a lot, the surface outline of the work piece is negative, the bearing length rate is cliffy. Also the surface quality of the work piece is improved. This can help to avoid changing the shape, improve the feature of rub, gear and reduce the time to suit. This would also ensure the precision and result in a longer work piece life.

The Hilbert amplitude envelope of the stator current includes the low frequency of fault characteristic, thus it can reduce the signal length by resample the Hilbert amplitude envelope of the stator current by downsampling, which can avoid spectrum aliasing. Then it can reduce the computation time of the MUSIC Method for the spectrum analysis to the resampled signals for the given bandwidth. Meanwhile combining continuous subdivision Fourier transform and rotor slot harmonics based slip estimation it can in advance estimate the concrete values of the fault characteristic frequency, and then inquiry purposely the fault feature component information in the stator current spectrum in order to accomplish the broken rotor bar fault with high sensitivity and h reliability, which eliminates adverse effect of issuable false peaks to the fault detection and formed a novel scheme to detect broken rotor bar fault.

企业包袱沉重、机构人员臃肿、设备实力弱（2 1.5m3和2 1m3搅拌机组）等缺陷使省建混凝土公司在激烈的市场竞争中逐渐处于劣势。省建公司在南京市的工程本身就很少，这也使得混凝土公司全部对外经营，享受不到任何大树底下好乘凉的美妙感觉。

The inhibition substances in Sorbus pohuashanensisHedl fruit not only restrained the seeds of wheat, cabbage from germinating but also restrained height and root growth. After the seeds of wheat, chinese cabbage had been soaked in the water extraction of pulp, seed and decoated seed for 8h, the seed germination rates were 92% and 84%, 89% and 65%, 94% and 78%, lower than the control, especially the water extract of decoated seed; and the root length and seedlings height were lower than the control, especially the water extract of pulp, and decreased in sequence of soaking time from short to long. So the simplest and effective method to eliminate pulp soluble inhibiting substances is to wash fruits by flowing tap water soon after collection.

在几种浸泡时间中，浸泡8小时的去皮种子浸泡液对白菜、小麦种子发芽率的抑制作用最为明显，其发芽率分别为65%、89%，但随着浸泡时间的延长而降低；浸泡8h的果肉浸泡液对白菜和小麦幼苗高生长和根伸长的抑制作用最为明显，种子和去皮种子浸泡液(8h)的抑制作用对小麦和白菜的抑制作用次之，随着浸泡时间的延长，果肉浸泡液的抑制作用逐渐减弱，因而采收下来的果实及时净种是清除果肉水溶性抑制物质简单有效的方法。

Nothing is more destructive, either in regard to the health, or the vigilance and industry of the poor than the infamous liquor, the name of which, derived from Juniper in Dutch, is now by frequent use and the laconick spirit of the nation, from a word of middling length shrunk into a monosyllable, intoxicating gin, that charms the unactive, the desperate and crazy of either sex, and makes the starving sot behold his rags and nakedness with stupid indolence, or banter with in senseless laughter, and more insipid jests; it is a fiery lake that sets the brain in flame, burns up the entrails, and scorches every part within; and at the same time a Lethe of oblivion, in which the wretch immersed drowns his most pinching cares, and, with his reason all anxious reflections on brats that cry for food, hard winter's frosts, and horrid empty home.

没有什么比之&松子酒&这样一种臭名昭著的酒对于穷人们的健康、神经警觉和工作更为有害的东西了。这酒的名称原本来自荷兰语中对于桧类树木的称谓，现在，在一个崇尚简洁精神的国度里、通过经常性的使用，从一个中等长度的词汇压缩成了单音的、醉人的&松子酒&，迷惑着那些麻木绝望痴迷的男女，让饥饿的人带着愚昧的懒惰用袋子裹着裸体的身子干坐，或是无聊地说笑，讲着乏味的笑话活着；彷佛是个满是酒精的湖，把这些人的脑子点着了火，燃烧到肠子，烧到身体的各个部位；同时，忘神来了，把酒鬼们最后一点在意都淹没掉，一点良心都没有，不再焦虑地看着自己那些哭着要食物的儿郎，不再顾及冬天的霜冻和可怕空旷的家。
