全文共分四部分，第一部分论述了近代一些主要的阶级关注西北的言论和思想；第二部分对西北近代工矿业开发的三个最重要的阶段，即洋务运动时期、清末"新政"时期、抗日战争时期的开发过程做了梳理，并对每一个阶段的特点做了初步地概括，大致可以归纳为军事性、封建性、买办性以及国家垄断性等；第三部分对西北近代工矿业开发成效不高的原因做了论述，主要有四点：第一，小农业与家庭手工业紧密结合的自然经济占统治地位；第二，生产力水平低下，科学技术落后；第三，缺乏资金的积累和投入；第四，缺乏政府系统的政策支持和保障。

Low-level noise can cause higher probability of subjective annoyance. It"s very slightly to people"s health, sleeping and working about the low frequency noise. It was compared with the high frequency noise caused by traffic about sleep, work and rest.

研究结果表明：居住区低频低噪声引起的烦恼度不容忽视，在低频低噪声环境下仍能引起较高的烦恼概率；低频低噪声对人的睡眠、行为及主观生理不适感有影响；低频噪声烦恼度与中高频噪声烦恼度的研究结果在对睡眠、工作及休息上有差异。

But recently, the development of it has been slowed down because of problems, such as low speed, low level of service. So the bus traffic cannot develop swimmingly.

To simulation of weather patterns, the capability of stimulation to 850hPa is not as good as the one to 500hPa, which may be caused by underlying surface. In addition, the capability of stimulation to 48h is also not as good as the one to 36h. By analysis of result of stimulation to heavy rainfall happened on 8 July, 2003, we have found that rain belt location and its heavy rain core amounts in sensitivity run are preferably displayed by MM5V3. Analyses indicate this event was in close relationship with the southwest low vortex moving to east from the Tibetan Plateau and low-level jet in front of vortex and shear line.

模拟结果总体的TS评分、大雨以上准确率及暴雨以上准确率较MAPS模式都普遍更高；在对天气形势场的模拟能力方面，模式对850hPa上天气形势场的模拟效果不如500hPa上的模拟效果好，其可能原因是受下垫面的影响所致，并且总的看来，36小时的模拟效果优于48小时的模拟效果。

In the article, we analysised the rainstorm process using conventional information, encryption data, strength ,speed and wind profile data of Doppler radar, discussed the atmospheric circulation system in the westing process of the subtropical high; revealed the different reasons caused two heavy precipitation (more than 10 mm per hour) and the possibility of small and medium-scale system existed, displayed the vertical distribution of the wind field over the stations in the rainstorm process and the close relationship between the transmission., strengthen of the level air-jet and the heavy precipitation, and then proved that the heavy precipitation was caused by the transmission and strengthen of the low-level jet.

利用常规资料，加密观测资料，多普勒雷达强度、速度和风廓线资料等对本过程进行周密细致的分析。探讨了在副热带高压西进过程中与之相配合的大气环流形势和影响系统；揭示了造成两次强降水（1小时大于10 mm以上）的不同原因和中小尺度系统存在的可能性；展示了暴雨过程中测站上空垂直风场的分布特点以及风廓线高低空急流下传和加强与强降水的密切关系，证明了强降水的产生主要由低空急流的下传和加强引起的。

The results showed as followed:low level NO could keep Sertoli Cells' microtubule and cell viability normally,and high level NO could increase the activity of p-38MAPK of cells, decrease antioxygen ability and cell secretion and destroy the structure and distribution of microtubule.

结果表明，低浓度NO能维持支持细胞正常的骨架和活力，而高浓度NO能提高SC内p38MAPK的活性，降低抗氧化酶的活性和破坏细胞内微管的结构和分布，甚至细胞的分泌功能。

Bi-level refers to two levels. For sync, this means apulse having two voltage levels (a high and low level, relativelyspeaking), hence the name.

双电平指的就是两个电平，对于同步信号来说，顾名思义，这意味着一个脉冲包含了两个电平值（相对而言，就是一个高电平和一个低电平）。
