According to the result of artificial rainfall, the character and factors affectedby soil, rainfall, chemicals, slope length, slope gradient and field mangment practices, for rainfall, runoff,infiltration, soil erosion and soil chemicals, such as NO_3~-, NH_4~+, PO_4~(3-), K~+ and Br~-, are investigated. Thedeterminate methods, influence factors and practical application of the mixing zone depth are also researched.The results can enrich the dynamics of soil, water and nutrient transport, evaluate the soil water and fertilizerefficiency, and theoretically benefit the research of agricultural NSP on loess hill slope. 1. According to the surface transport experiments of soil chemicals under the non-satuation soil and watererosion condiction, for adsorbed PO_4~(3-) and K~+, the time of sheet erosion and rill erosion initiation is coincidentthat of chemicals content in surface runoff climbs, and then their abundant export by surface runoff is urged.

When tractor runs in the shipside, due to low speed, do not need to climb and wait for a long time, the engine works in the low efficient field, that results in low utilization rate of fuel and higher emissions.

牵引车在集装箱码头的运行中由于具有速度低，不需要爬坡及怠速时间长等特点，这样使汽车发动机工作在低效区，导致燃油利用率低，排放高等问题。

By applying in seven spot, the directional control blasting technology by using slotted cartridgc has been confirmed that can increase the distance of hole in perimeter 50% on present basic, the ratio of half hole scar to 85%～95%, and the utilization ratlo of shot hole 10%.

通过在山东、山西、安徽、河南等省的七个矿区现场应用，证实了采用切缝药包定向断裂控制爆破技术，可使周边眼间距在现有基础上增加50％以上，周边眼的炸药单耗降低30～50％；循环炮眼数减少15～25％；炮眼利用率提高了10％以上；半眼痕率提高到85～95％；周边不平整度小于100mm，这一指标是目前国内外岩巷生产中最佳指标；每米岩巷掘进成本可降低200元以上，展现了定向断裂爆破技术广阔的应用前景。

A chemical method for refining silver nitrate from the waste water was given and the Ag-ntilization was raised from about 80% to more than 95%.

采用了化学方法从废水回收银盐，使银利用率从80％左右提高到95％以上。

As a parallel transmission technique with multi-carriers, Orthogonal Frequency Division Multiplexing is very suitable for high data rate transmission because it has the advantages of being robust to frequency selective fading, high spectrum efficiency and simple equalizer.

正交频分复用作为一种多载波并行传输技术，能够有效对抗多径信道的频率选择性衰落，同时具有较高的频谱利用率，接收端的均衡也很简单，非常适合于高速率数据传输。

In this paper, a CWE model of the distance education system is provided. In order to enhance the bandwidth utilization factor, a transfer method based on multi-channel is presented. Both the transmission of real-time media stream and time-stamp technologies are introduced to the system to ensure the requirement of real-time characteristic and synchronism, and a simple protocol based on RTP (Real-time Transfer Protocol) and UDP is designed. The method, event simulcast, is also brought forward to reduce the data redundancy and expand the collaboration scale of the system.

本文给出了远程教学的协同工作环境模型；设计中为了提高系统带宽利用率，采用一种更符合实际应用要求的"单播+广播"的有效通信方式；为了解决音视频同步问题，参考实时媒体流和时间戳同步技术，设计了一个基于用户数据报协议UDP和实时传输协议RTP的简单传输协议，实际应用中保证了数据的实时性和同步性；系统采用基于显示同播的事件同播方式，这样在一定程度上降低了数据冗余，同时扩大了系统的用户数量。

Our technology develops a single step method of producing biodiesel from the waste plant and animal oil by using DYD catalyst to carry out transesterification and esterification simultaneously.

本技术可使用不同酸价的油脂为原料，在常压下反应，反应转化率可达96%，油脂利用率100%，所获得的生物柴油产品的品质达到美国ASTM 6751标准。

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。
