不定时

Programmers need to learn to think like security professionals, to some extent, so that their influence on the architecture of the software they develop will tend toward greater security; network administrators and architects need to learn such skills to ensure that their implementations of networking technologies will not create terrible security debacles waiting to happen; Web developers need to think like a security professional, with all the practical paranoia that entails, so that they will realize the ways publicly accessible Web applications and services can be abused and twisted to nefarious ends, and plan accordingly.

在一定程度上，程序员需要学会像安全专家那样思考，从而影响他们所开发的的软件结构，将倾向于更大的安全；网络管理员和构建师需要学习这种技能，以确保其实施的网络技术将不会产生定时的可怕安全事故。网页开发者需要像安全专家那样思考，利用所有必需的实际揣测，从而察觉到可公开访问的Web应用程序和服务可以被滥用和扭曲到相应的违法目的、计划的途径。

PET was first depolymerizd by using glycols into glycolizd monomers and oligomers.

PET一定时，DCPD的含量影响不饱和聚酯同苯乙烯的互溶性和固化过程。

The high library building and the clock tower gave the Guan family a lot of pressure, so the Guans launched a library association. In five years, the Guan family built a library along the west river of Chikan town facing the Situ's library.

高耸的司徒氏图书馆和定时响起的钟声对关氏家族形成很大压力，翌年关氏族人就成立了关氏图书馆筹建委员会，不到5年时间，关氏图书馆就矗立在赤坎上埠堤西河畔，与堤东的司徒氏图书馆遥首相望。

No claim for constructive total loss based upon the cost of recovery and/or repair of the Vessel shall be recoverable hereunder unless such cost would exceed the insured value in the insurance on hull and machinery In making this determination, only the cost relating to a single accident or sequence of damages arising from the same accident shall be taken into account

基于保险船舶的恢复和/或修理费用不能据此得到赔偿，除非此种费用已超过保险价值。在作此项决定时，仅应考虑与单一事故或由于同一事故引起的后续损害赔偿有关的费用。

Suntraps therefore are good at modifying local climates. This could be very useful in future years of climate instability.

避风面阳处因此成为调节在地气候的关键，特别是在未来的气候将变得极不稳定时。

In retiming registers are added at some points in a circuit and removed from others in such a way that the functional behavior of the circuit as a whole is preserved. By retimng we can optimize the speed, area or power of the circuit.

重定时在保证功能不变的前提下，通过移动时序元件的位置和改变时序元件的个数来优化同步时序电路的速度、面积和功耗。

Beacouse circuitry net list which is synthesized by synthesizer may not achieve the demand of the designer, the sequence circuit which is synthesized must be optimized under require of speed. Retiming is one of the important techniques of optimizing sequence circuit.

但是由于综合器综合得到的电路网表不一定能达到设计者的设计要求，所以需针对给定的速度要求，对综合得到的时序电路进行速度优化，其中针对时序逻辑的重定时优化技术，便是一种重要的优化技术。

Traditional concurrency control methods constrain the concurrency of transactions and are disadvantageous to satisfaction of Real-Time transactions' timing constraints. We develop a novel quasi-consistent serializable concurrency control strategy. The inconsistency brought by transactions to the system was restricted to an extent.

传统的并发控制策略限制了事务执行的并发度，对实时事务定时限制的满足是不利的，我们开发了一种适合于实时应用环境的新颖的&准一致性可串行化&并发控制方法，事务给系统带来的不一致程度被限定在一定范围内。

II floating roller DAncEr: tension, such as shown in Figure 2 it is an indirect way of tension, is essentially a kind of position control, when the tension, the tension on the Strip andcylinder forcing balance to roll in a central location.

浮辊式压力检测方法：（如图2所示）它是一种不直递的压力检测方法，本色上是一种场所把持，当压力安定时，料带上的压力与气缸息用力保持不均，使浮辊处于边际场所。

Comparison of different types of stem cutting in rooting induced and analysis the cDNA clones which may be associated with the occurrence of adventitious roots of P.euphratica,the model of ARF were initial establishment of exogenous IBA controlling endogenous IAA occurred threshold and equilibrium,that is,exogenous IBA receiving by receptor of stem cutting,and transfer into the cells,then turn into active IAA by the effects of the POD enzyme.

通过对胡杨3个不定根发生调控培养体系的比较和与胡杨不定根发生可能相关的差异基因的克隆分析，初步建立IBA调控胡杨不定根发生的内源IAA阈值和激素间平衡的模型，即外源IBA通过插穗受体接收，转入细胞内并在POD酶作用下转化成具有活性的IAA，当IAA的水甲在促根的阈值内并保持相对平稳时，则有利于生根；当IAA的浓度增高超过阈值且不稳定时，则抑制不定根的发生。

For a big chunk of credit-card losses; the number of filings (and thus charge-off rates) would be rising again, whether

年美国个人破产法的一个改动使得破产登记急速下降，而后引起了信用卡大规模的亏损。
