不适应性

One measure, perhaps, of a book's worth, is its intergenerational pliancy: do new readers acquire it and interpret it afresh down through the ages?

衡量一本书的价值，也许正是其跨越时代的适应性：它难道不正是那种能让新的读者穿越若干世代不断从中获取营养并不断从中诠释出新意义的著作吗？

The advantages and limitations of every kind of methods for calculating the failure probability is reviewed. The frist order reliability method, the second order reliability method and many kinds of boundary method have achieved remarkable success and formed nature fields of reliability. However, the precision of these methods decrease as the increase of complexity of problem. The numrical methods are versatile, except numerical intergration is only adaptable to special problems which have small number variables and regular intergral domain. Particularly, the advanced variance reduction techniques own the following character: high precision and a small amount computation. But some questions remain to study in the future because only an initial work about these techniqes is developed.

全面评述了计算失效概率各种方法的优点和局限性，其中经典的解析法包括一次可靠性方法、二次可靠性方法、一阶边界法、Vanmarcke上边界、PENT上边界和Ditlevsen二阶窄边界法，这些方法对于多设计点、变量较多且相关、密度函数不是正态以及极限状态方程较复杂的情况，其计算精度较差；而已有的数值方法却是具有较好的通用性，其中除数值积分法只对变量较少、积分域较规则的特殊问题适用外，各种数值模拟方法均具有较广的适应性，特别是各种改进的方差减小技术，精度高、计算量小，但由于其处在研究的初级阶段，还有许多问题有待于解决。

This product works on the principle that the inertial vibrating riddler almost reaches resonance. It had a high rate of screening and big swing of the screening machine that it does not jam the screen sieve. It is also of great adaptability to materials. The main vibrating spring uses cutting rubber spring which has low noise, and a long life. It is sealed to prevent environmental pollution. The working efficiency is 3 times than that of the original frequency. It has a good anti-vibrating effect.

The optimal reconstruction windows of patients with stable HR(≤75 bpm and≥91 bpm) were concentrated in 71%,ranged from 65%-80%, and in 41%,ranged from 32%—50%,respectively.The prospectively ECG-gated DSCT coronary angiography can be used in patients with stable HR(≤75 bpm and≥91 bpm) in abstract.②To explore the clinical application of prospectively ECG-gated transverse DSCT coronary angiography.Methods Two hundreds patients[Body mass index:23-25 kg/m~2,122 patients(average HR≤75 bpm),78 patients(average HR≥91 bpm)]with suspected or known coronary artery disease underwent prospectively ECG-gated transverse DSCT coronary angiography,among them,30 patients underwent selectively coronary angiography,grouping them into 2 groups according to the average HR of scanning.Group A(17 cases,HR≤75 bpm),group B(13 cases, HR≥91 bpm),the DSCTA results were compared with SCAG.Then,calculate the accuracy of patients in each group and evaluate the agreement of accuracy between DSCTCA and SCAG by Kappa statistics.

方法回顾性分析200例行适应性前瞻性心电门控双源CT冠状动脉血管成像的患者(排除扫描过程中，屏气配合差，出现心律不齐的患者及行支架置入或搭桥术后复查的患者)，包括屏气时平均HR≤75 bpm患者122例，HR≥91 bpm患者78例；其中30例同期行选择性冠状动脉血管造影，按屏气时HR将其分为2组，A组17例：HR≤75 bpm，B组13例：HR≥91 bpm，分别与金标准SCAG对照，计算2组患者的阳性诊断准确率，应用SPSS 13.0统计学软件，利用Kappa检验比较每组患者的2种诊断方法诊断结果的一致性，利用两样本率x~2检验，比较2个心率组间的诊断准确率有无明显统计学差异，并计算此30例患者的平均有效辐射剂量。

So it could turn out that what now looks like European resilience may seem, in retrospect, to have been European sluggishness.

所以，当我们回顾时会发现，现在欧洲经济的强适应性乃是它的呆滞和不振了。

We use the single Fuzzy Control to control algorithms , adopt the traditional one-chip computer temperature control system, temperature of bed is it control to go on to smeltery electric heat, in order to is it work systematic dependability and security to improve, achieve the with high efficiency , high-standard goal.
