Presents the design of longitudinal control for ASTOVL lift-fan aircraft, a multi-variable, strong-coupling, complicated nonlinear system to make the system nonlinear offset and decouple, and the method used for linear system in designing the system to gain expectant flying qualities and the combination of aerodynamic control surfaces with thrust vectors to delay the control surfaces getting into saturation, and the minimum N-norm generalized inverse theorem of weighted generalized inverse adopted to apportion the moments commands, which make the control surfaces gain appropriate deflection and the simulation results to verify the dynamic inverse control laws designed really make the system nonlinear offset and decouple; when one command is given, only this output will response, and others do not response; when all commands are given together, the responses will be just the linear superpose of the response of each command, therefore the operation of the pilot will be simplified greatly.

摘 要： ASTOVL升力风扇飞机是多变量、强耦合、复杂的非线性系统，采用非线性动态逆理论设计控制律以实现系统的非线性对消及解耦，然后，采用线性系统的设计方法对系统进行设计，以使系统获得期望的飞行品质。同时，考虑到ASTOVL升力风扇飞机是由气动舵面和推力矢量融合作用的，为了延缓各舵面进入饱和的时间，采用加权广义逆中的极小N-范数广义逆定理分配力矩指令，从而使各舵面达到适当的偏转角。并将所设计的控制律进行了仿真，结果验证了所设计的动态逆控制律使系统实现了非线性对消和解耦，单个指令作用时，只有该项响应，其余不受影响；所有指令作用时，其结果就等于单个指令作用时的线性叠加，这样使驾驶员的操纵大大简化而易于控制，从而大大降低了飞行事故率。

In set 1 (n=6), After 30-min suffusion of GLB, the vasodilator effect of diazoxide (3*10/sup -4/M, an opener of K/sup +//sub /channels) was abolished, whereas the vasodilator effect of sodium nitroprusside (3*10/sup -6/M, an exogenous nitric oxide donor) remained the same.

於第一组的6只动物中验证GLB的作用专一性，经过30分钟的GLB作用，3*10/sup -4/M的Diazoxide(为K/sup +//sub ATP/的活化剂)的作用近乎完全被抑剂，而3*10/sup -6/M的Sodium nitroprusside(为外来一氧化氮的供给剂)的作用不受影响。

As the guests one by one pack, pay, and depart, and the seats at the table-d'hote shrink pitifully at each succeeding meal; as suites of rooms are closed, carpets taken up, and waiters sent away; those boarders who are staying on, en pension, until the next year's full re-opening, cannot help being somewhat affected by all these flittings and farewells, this eager discussion of plans, routes, and fresh quarters, this daily shrinkage in the stream of comradeship.

旅客们一个又一个收拾行装，结帐离店，公共餐厅里每开过一顿饭，坐椅就撤去一批，怪凄凉的。一套套房间关闭了，地毯卷起来了，侍者辞退了。而那些长住的客人，则留下等待来年饭店全面开业。他们眼瞅着大批旅伴飞走的飞走，告别的告别，热烈地谈论着下一步的计划、路线和新居，眼瞅着伙伴的人数日渐削减，心情难免不受影响。

The biggest advantages of this fashion is that when single-phasegrouded, three-phase line voltage symmetry was not damaged, so electricity userswill not be affected.

这种接地方式最大的优点是：当发生单相接地时，三相线电压的对称性没有被破坏，所以用户有电不受影响，可维持一定长的时间，这对电网结构比较薄弱，自动化水平比较低的配电网是至关重要的。

This platinum process was highly praised by Alfred Stieglitz and other pictorial photographers in the early years of the twentieth century.

在1873年发明。与银盐法不同，铂钯元素不受光的影响，印像过程依据的是一定量的铁盐合成在紫外光的作用下按照曝光的时间和强度而改变。

That adding the little metallic ion hardening agent not only improves the content of microelement and nourishment, but also shortens the cooking time, reduces the filming temperature, and improves the productivity and filming speed. The bean curd sheet rolls keeps the brightness and toughness.

其中添加少量的金属离子型营养强化剂，不仅增加了腐竹中微量元素的含量，提高了腐竹的营养，而且缩短了煮浆时间，降低了成膜温度，提高了腐竹的产率和成膜速率，所得腐竹品质更加均一，腐竹的光泽和韧性基本不受影响。

Unlike silver salt, platinum compounds are not affected by light; the process depends on the fact that the composition of certain iron salts is altered by the action of ultraviolet light in proportion to the length and intensity of exposure.

Practice lifting your shoulder and chest as your arms pull so that your shoulders are clear of the water.

练习当你向外推胳膊的时候抬起你的肩膀和胸部，这样你的肩膀就可以不受水的阻力的影响了。

It was observed as follows:(1)The body temperatureof the cord transectedanimals fell in a good agreement with ambient temperature.It appears thatthe fall in B.T.is one of the main causes inducing ulceration.(2)Administrationof epinephine decreased ulceration and prevented the fall in B.T.both in a dose-dependent manner.(3)Cord transection induced ulcer formation was markedlyattenuated by adrenalectomy and exacerbated aga...

结果表明：(1)脊髓横断动物的体温随环境温度而下降，体温的下降可能是诱发溃疡的重要原因之一；(2)注射肾上腺素可减轻溃疡和防止体温下降，且两者均呈剂-效关系；(3)切除肾上腺可使脊髓横断诱发的溃疡明显减轻，如补充注射地塞米松则可使之重新加重，但体温的下降在以上情况下均不受影响；(4)脊髓横断后胃粘膜泌酸和内分泌功能的改变可能与溃疡生成有关。

The enlargement test of pumpkin polysaccharide preparation technology showed little change in the monosaccharide composition, the yield and the hypoglycaemic activity of PCE-C, and thus ensured the feasibility of extraction technology and the reliability of the PCE-C product.

活性南瓜多糖制取工艺的放大试验表明，提取工艺的放大后，产品PCE-C的单糖组成、得率及其降血糖活性均不受影响，从而肯定了提取工艺的可行性和产品PCE-C的可靠性。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
