It was also found that the protecting effect of erodents on the coating surface does exist. The protecting effect will be more evident if using erosion efficiency of unit mass erodent of sand in the slurry to describe the erosivity of erodent. Besides a model is proposed to explain the protection process. The wear mechanism of the coating is the co-operation of ploughing, cracking and ablation.

对涂层的SEM分析可知，除冲蚀粒子在涂层表面的犁沟作用，冲蚀磨损的结果造成涂层的表面生成了系列针孔，其中的一部分为溶剂挥发所至，另外还存在由增强颗粒的剥落和裂纹的扩展造成的涂层剥落产生的孔洞，这将可能为水的吸收和扩散造成有利条件，使复合涂层亚表层产生内应力。

Because a speech signal is produced by the interactions between the glottal flow derivative and human vocal tract, we assume that the speaker identity information is included in the glottal flow derivative waveform, in this thesis we setup some experiments to verify the assumption.

由於语音讯号的产生是由声门来源波型与人体口腔交互作用产生，而我们假设声门来源波型包含大部分语者生物特徵，进而以本论文中的实验加以验证。

As the results, the ultra-thin films of 500SN and hexadecane exhibited nonlinear shearing response, which was different from that of the Newtonian fluids in their bulk state.

结果表明：在超薄膜润滑条件下，5 0 0 SN和十六烷均表现出明显的非牛顿剪切响应，即剪切稀释现象；摩擦力幅值随剪切速度的增大急剧上升到最大值，然后下降至某一固定值附近并产生波动；剪切挤压下的临界膜厚小于静态挤压的临界膜厚，剪切运动对吸附层有序结构产生破坏作用

Duffing equation has parameter and initial value sensitivity. It can generate chaotic state by adjusting the parameter and initial value, and it also can generate intermissive chaotic state, if the ideal signal and the measured signal applied to the system simultaneously. The actual measured signal can be measured by using this state.

Duffing方程具有参数敏感性和初值敏感性，通过调节Duffing方程的参数和初值可以产生混沌现象，且被测信号和理想信号如果共同作用在Duffing方程上，可以产生有规律间歇混沌现象，利用这种现象就可以实现周期信号的频率测量。

The biased magnetomotive forces generated by the permanent magnets were superimposed on the coil control magneto-motive forces to act on the rotor, making the solenoid produce bidirectional output torques proportional to the coil excitation currents.

永磁体产生的偏置磁通与线圈产生的控制磁通形成差动磁场作用于衔铁转子，使电磁铁输出与控制电流成比例的双向转矩。

The results indicated that sclerotia was an important sign and a necessary stage in the formation of the fruit body;light,temperature and humidity were the key factors;"Beiqi"residue can stimulate the forming of the sclerotia and the fruit body;the most suitable culture areas for Morchella were poplar forest land and apple orchard;and woodash and poplar-root soil can promote the forming of the fruit body.

结果表明，菌核是羊肚菌子实体产生的重要标志和重要阶段；光照、温度和湿度是子实体形成的关键因子；北芪渣对菌核和子实体的形成有刺激作用；人工栽培适宜在杨树林地和苹果园进行；草木灰和杨树根土可促进羊肚菌子实体的产生。

Seen from clinical effect, haemodynamics and general condition both better in rats treated with dexamethasone than rats treated with saline. We had a presumption on these grounds that the sum of negativity myodynamia generated byβ3-AR up-regulation andα1-AR down-regulation possibly less than positive myodynamia generated byβ1-AR up-regulation. 5 For patients with DCHF, adding prednisone to the usual care resulted in significant relief of the congestive symptoms, which was accompanied with a potent diuresis with time and an improvement in renal function.

从临床效果来看，地塞米松治疗的心衰大鼠在血流动力学及一般状况上，都明显优于注射生理盐水的心衰大鼠，据此推测，β3受体上调和α1受体下调产生的负性肌力之和可能弱于β1受体上调产生的正性肌力。5对于失代偿的充血性心力衰竭病人，在心衰常规治疗基础上加用强的松这种糖皮质激素能显著缓解充血症状，并伴随着强有力的利尿和改善肾功能的作用。

Under the loads of upside soil and vehicles, those pipelines buried in soft soil are prone to produce longitudinal bending and overlarge deformation, these two influences will cause pipelines to lose stability and to produce breaks in the weakest parts, which will lead to leakage and even blowout. These accidents will influence normal operation of national economy and peoples daily lives, and bring serious economic and social damages.

埋在软土地基中的管道，受上部覆土荷载及车辆荷载的作用，容易产生纵向弯曲以及过大的变形，致使管道失稳，在最薄弱处产生破裂而导致渗漏甚至爆管事故，影响国民经济和日常生活的正常进行，会带来严重的经济和社会损失。

Mosquitoes captured and the egg positive traps were counted and recorded every day. Results Comparing with the control group, yeast-generated CO2 could take a strong attraction to mosquitoes in the field (P.05), but had an adverse effect in laboratory. P. maximum infusion, tyre infusion and L-lactic acid dilution could not attract Aedes albopictus to oviposit in Mosq-ovitrap. The colour change of Mosq-ovitrap could not raise its attractant ability to mosquitoes, on the contrary, increase the probability of mosquito escaping from Mosq-ovitrap.

结果 实验室和现场的结果显示，酵母发酵产生的CO2在室内实验中没有增强诱蚊诱卵器的诱蚊效果，而在现场实验中却产生较好的诱蚊作用，实验组的诱蚊指数和诱蚊密度指数与对照组比较差异均有统计学意义(P.05)；大黍叶、轮胎浸出液和乳酸稀释液在试验中未显示出吸引白纹伊蚊雌蚊产卵的能力；在改变诱蚊诱卵器杯身颜色的试验中，杯身上2/3变为黑色并不能提高它的诱蚊和诱卵能力，反而增加成蚊逃逸的概率。

Therefore, there're only single charged parent ions of the sample gas molecule under the condition of photons' irradiation effect, and no fragment ions produced. Consequently, the mass spectra obtained from photoionization is very simple, and the sample gas can be detected without preseparation.

样品气体分子在光子的照射作用下只产生单电荷母离子，不产生碎片离子，以该电离方式获得的质谱图非常简单，因此气体样品不需分离即可进行检测。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
