该方法将半解析函数作为插值函数，将缺口尖端附近的自由度通过位移场的扩展公式转化为一组广义坐标。

Plane strain, mode I quasi-static steady state crack growth is investigated utilizing the finite element method. It is once again established that TNT plasticity can significantly increase the stress level near the crack tip. The crack tip stress singularity is higher than or equal to the square-root singularity of elastic K field and is also independent of the plastic hardening exponent.

采用有限元方法研究了平面应变Ⅰ型准静态的稳态裂纹扩展，再次证实TNT非局部理论能够显著提高裂纹尖端附近的应力水平；裂尖应力场的奇异性超过或等于弹性K场平方根奇异性，而且与塑性硬化指数无关。

In 1950, therefore, Hiller abandoned the pressure-jet approach to tip propulsion and dedicated his company to experimentation with tip-mounted engines.

1950年，因此，希勒放弃了给小费推进压力喷射方法和专用他的公司与尖端式发动机试验。

The TTB-USA we used in our study is the production of IBI corporation, it has two electrode at the tip of a 7F catheter, its tip and ablation temperature can be controlled.

本实验应用的是一种新型的超声球囊导管(through the balloon ultrasound ablation system，TTB-USA)，它将一个换能器安放在7F电极导管顶端，外面用一弹性良好的球囊包裹，在造影的引导下，把带有球囊的导管顶端置放于需消融处，用稀释的造影剂充盈球囊，然后发放超声波产生一个环状损伤，达到阻断电传导的目的。

In conclusion, by consideration of viscosity effect of material at propagating crack-tip, it is established in the paper the unified continuous singular crack-tip field in linear-hardening material under the condition of incompressibility. The plastic shock is eliminated that exists in non-viscosity solutions. What's more, the dynamic and quasi-static solutions are united together when the Mach number approaches zero.

总之，通过考虑扩展裂纹尖端材料的粘性效应，本文建立了幂硬化材料在不可压缩条件下扩展裂纹尖端的统一的连续奇异性场，消除了无粘性解中存在的塑性激波，在马赫数趋于零时动态解和准静态解得到了统一。

You don't tip more than 10%at a restaurant,and if you do,you tip Chinese de livery guys/waiters more.

你不会给超过10%的小费，即使有也是给中国服务员。靠，我都是给15%的，给10%人家恨死你。

For the compressible materials, in order to satisfy the higher-order compatibility equation of the rate of deformation in the centered fan sector, which is a quite difficult problem unresolved in the previous studies, a particular term must be added to the expansions of the stress components in the regular logarithmic power series adopted by many researchers before. A higher-order near tip field with tangential velocity jump ahead of the crack tip is derived first, of which the dominant terms are the solution widely accepted.

对可压缩材料，本文首先采用非规则的对数幂级数渐近展开方法，克服了过去研究中存在的中心扇形区变形率协调方程的高次渐近式不能被满足的困难，并得到了一个切向速度在裂尖前方存在间断的高阶渐近解，该解的主项就是目前被广泛接受的关于可压缩材料的尖端场解。

The lateral friction of piles developed with small displacement mutably. At the same time, the tip resistance could not develop. So the tip resistance should be cautiously considered when the bearing capacity of extra long piles was designed.

桩侧摩阻力发挥所需位移较小且有突变性，桩端阻力则基本不能得到发挥，超长桩在承载力设计时应谨慎考虑桩端阻力。

The results showed that the number of chromosome, which was from the cultured seedlings of meristem tip and the rank seedlings of meristem tip, was not altered, both the number were 2n=16,the hereditary stability of callus and regeneration plant was poor; and the variation percentage of chromosome in callus was 43.4%, among which haploid accounted for 6.7%, triploid accounted for 2.5%,tetraploid accounted for 10%,pentaploid accounted for 4.2%,hexaploid accounted for 3.3%,septuploid accounted for 4.2%,octoploid accounted for 3.3%,dysploid accounted for 9.2%;the chromosome variation percentage of differentiation seedlings derived from callus was11.7%,among which haploid was 6.7%,triploid accounted for 1.7%,tetraploid was 3.3%.

结果表明，茎尖分生组织培养的幼苗及丛生苗遗传稳定，其染色体未发生倍性变异，均为2n=16；愈伤组织及其再生苗遗传稳定性较差，愈伤组织染色体数变异率为43.4%，其中单倍体占6.7%、三倍体占2.5%、四倍体占10%、五倍体占4.2%、六倍体占3.3%、七倍体占4.2%、八倍体占3.3%、非整倍体占9.2%；愈伤组织分化苗染色体变异率为11.7%，其中单倍体占6.7%，三倍体占1.7%，四倍体占3.3%。
