常常地

Very often the ego experiences a vague feeling of moral defeat and then behaves all the more defensively, defiantly, and self-righteously, thus setting up a vicious circle which only increases its feeling of inferiority.

自我常常会体验到一种含糊的道德挫败感，然后表现地更加防备对抗和自以为是，并因此导致了一个引起自卑感的恶性循环。

When she found her girl classmates all got boyfriends, having only her own shadow in her company, she felt really self-pitiful, she shed tears sometimes privately and lonely .

她见同班的女同学皆有了男友，惟独自己形影相吊（have only her own shadow in her company），便感到挺自卑，还常常悄悄地掉泪。

This happens more often in persons who have a low risk for the disease for which they are being tested.

这更多地常常发生在人谁拥有一个低风险的疾病，他们正在测试。

In the process of building and using the mass concrete structures, because of the effect of out-side condition and themselves, some faults will form in the structure, these faults will effect the bearing capability and endurance Using nondestructive testing method to test the concrete"s quality and diagnose its healthy, which has the significant sense in assessing the safety stability and research of the administering diseasesThis dissertation mostly researched the testing methods in the mass concrete structure, discussed the principles, methods, features, sphere of application of the ultrasonic testing in the mass concrete structure with faults, used dynamic FEM to simulate the testing process, discussed when the concrete structure with cracks is under the effect of the pulse, how the elastic waves propagate and what are their changing feature, Researched the principles of the first-arriving waves" phase when the cracks" depths are not same, obtained the relation between the inversion point and the cracks" depth, which has the direction sense in the application of projects,The second part of this dissertation is CT , which used the ultrasonic wave running through the tested-substance to get arriving-time of the ultrasonic wave, then inverse the image This dissertation drawed one CT program which can well present the different little cells ultrasonic wave velocity profiles of the substance, thereby to diagnose the quality of the part of the tested-substance, CT has the better using foreground..

在混凝土结构的施工及使用过程中，由于受其自身及外界各种因素的影响，常常会产生一些缺陷，对结构物的承载能力和耐久性造成严重影响，采用无损检测技术进行质量检测和健康诊断，这对混凝土结构开展安全、稳定性评估以及病害隐患治理研究具有重要意义。本论文主要针对大体积混凝土结构缺陷的检测方法展开研究工作，重点讨论了超声波法检测混凝土结构裂缝的基本原理和方法及其特点、适用范围，运用动力有限元数值模拟其检测过程，探讨了有裂缝缺陷的混凝土结构在脉冲荷载作用下弹性波的传播及其变化特征，研究了不同裂缝深度下首波相位变化规律，得出了反转临界点与裂缝深度之间的关系，这对实际工程应用具有指导意义。声波CT是一种新的无损检测技术，它是利用声波穿透被检测体获取声波接收时间，来进行计算机反演成像的技术。本文利用直射线法编制了层析成像程序，能较好地呈现被检测物体各微小单元的声波速度分布图像，从而对检测体的质量状况作出诊断评估，具有较好的应用发展前景。

In the faxless '60s, when TVs were still steam-driven and urgent correspondence was carried in the saddlebags of the Pony Express, news of Dylan's doings would often come limping along months after the event.

在信息传递不发达的60年代，电视系统还是蒸汽驱动，加急信件在驿马快递的包里递送，迪伦进展如何的消息常常在事件发生一个月后才跛行着到来（也可以说&断断续续地到来。&

Often it happens that when we wait in silence, life rushes back to fill those crevices in our souls.

常常，在我们在静默中等待的时候，生活却很突然地将那些旧伤涌上我们的心头。

Noise disturbs our sleep, prevents people from enjoying their time off work and too often leads to altercations when the police are called in.

噪音不但干扰大家的睡眠，使人们不能好好地享受下班后的时间，而且警察被叫来时还常常引起纠纷。

This limitation often leads to many protein crystallographers wasting significant time manually editing PDB files.

这个限制常常导致很多蛋白质晶体学家浪费重要的时间来手动地编辑PDB文件。

Ali Sina clearly ignores several facts contained within the Sirah itself; that the Prophet spared the Makkans who had tortured and killed his followers for two decades even after conquering them, that he spared all the hypocrites in Madinah undermining his authority (something the man Sina describes would not tolerate), that he had all too often freed prisoners of war freed for no material gain, that he explicitly forbade harming innocent civilians such as women, children, elderly and monks; that he always honoured his treaties even if they were extremely unfair to him (until the disbelievers broke them), that his stories are filled with instances where he spared men who were out to kill him, that as soon as someone became Muslim, he forgave all their past evils, betrayals and murders.

阿里新浪显然无视几个事实本身包含在希哈，那先知幸免 Makkans谁折磨和杀害了他的追随者，甚至二十年后，征服了他们，他不惜一切伪君子破坏他的权威在麦地那（东西的新浪人介绍不会容忍），他常常释放战俘获释无功利，他明确地禁止伤及无辜的平民，如妇女，儿童，老人和僧侣，他始终履行其条约，即使他们他极不公平的，他的故事充满情况下，他不惜在外面的人谁杀了他，表示只要有人成为穆斯林，他原谅了他们过去的所有罪恶，背叛和谋杀。

And so the young woman, sad and grieving, full of fear and forebodings, stopped asking questions, and sometimes at night she would piteously call out to him begging his to return; sometimes she would burst into tears over his absence, and in this painful state of waiting she remained without ever cheering up.

有时在夜里，她常常呼唤他，叫他快回来。有时由于他不在她身边，她竟哭出生来。这样苦苦地等待着，终日闷闷不乐。有一天夜里，她因为罗伦佐失踪哭的太久，竟然睡了过去。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
