突变压力

It is well known that the properties of water in the critical region may show anomalies in many of its physical properties.

实验说明：地球内部流体性质由深到浅不断变化，如水的密度、介电常数等物理参数随温度压力而改变，在临界态出现突变。

These skew reflect mainly those in protein coding sequences, which are driven by asymmetric mutation pressures during replication and transcription (notably asymmetric cytosine deamination) plus subsequent selection for preferred structures, signals, amino acid or codons.

这些不对称性主要反应在蛋白质编码序列上，并且主要是受到复制与转录期间复制双股之间的不对称突变压力加上之后为了偏好的结构、信号、胺基酸或转录子的筛选所驱使。

If average values before or after catastrophe point when the pressure at both ends reduces exceed the threshold value, judging that there is leak and positioning: calculating approximate wavelet transformation coefficient of pressure data at both ends, initializing searching interval, calculating a signal time delay value corresponding to approximate wavelet transformation coefficient in the searching interval from maximal scale N; converting the time delay value under scale N to that under N-1 by geometric proportion relation; updating the searching interval, repeating above processes until the scale is 0 and positioning based on the time delay value.

若两端压力下降突变点前后的均值变化均超过阈值，判定有泄漏并进行定位：计算两端压力数据的近似小波变换系数，初始化搜索区间，从最大尺度N开始在搜索区间内计算对应近似小波变换系数的信号时延值，利用等比关系将尺度N下的时延估计值转换为N-1下时延估计值，以该值更新搜索区间，重复以上过程至尺度为0，以此时延估计值进行定位。

Abrupt fluid contacts indicate a permeable reservoir;gradational ones indicate a low permeability with a high capillary pressure.

突变的流体界面表层储层具有很好的渗透率，而渐变的流体界面表明储层的渗透率较差，且储层的毛细压力较高。

In oil data analysis, for the existence of noise and the effort of singularity points, indention distribution is appeared, and normal analysis work is affected.

在油井压力测试数据中，由于噪声的存在和某些突变点的影响，使得数据呈现锯齿状分布，影响了正常数据分析工作。

Structural matter drops to hit water with fixed rate phut from certain height, inchoate and main the structure that attacks water process in the light of phut is answered begin research, and press mutation of field of force and Xing Bo to wait to study however to entering the underwater after water less, and add with each passing day as large bridge and marine project much, the construction in these projects and the phenomenon that phut of large construction content also appeared to hit water in use process, like Guangdong 9 rivers big bridge is bumped to break down after collapsing, large area bridge floor falls into surface to wait, the meeting such as mutation of field of pressure of the underwater after this kind of phut hits water and Xing Bo is right all round structural products gives birth to certain influence, evaluate this kind of influence to have real project sense to construction and design.

结构物从一定高度落下以一定速度砰击水面，早期主要针对砰击入水过程的结构响应开展探究，而对入水后水下压力场突变和兴波等却探究较少，而随着大型桥梁和海洋工程日渐增多，在这些工程的施工和使用过程中也出现了大型结构物砰击入水的现象，如广东九江大桥被撞垮塌后大面积桥面落入水面等，这种砰击入水后水下压力场突变和兴波等会对四周结构物产生一定影响，评价这种影响对施工和设计具有现实的工程意义。

When applied to a certain type of turbo engine, the result showed that the proposed model has high resolution for locations of pressure signal singularities, which are caused by stall air mass in the compressor; this method can be used in the early detection of surge signal.

对某型涡喷发动机压力测量信号的分析结果表明，该方法对由失速气团造成的压力信号突变具有较强的分辨力，可以用于发动机喘振的早期检测。

To test the influence of trehalose accumulation on response to freeze stress, we constructed all single and double gene disruption mutants of the trehalase genes ATH1, NTH1 and NTH2 and examined the changes of their trehalose accumulations and their freeze tolerance.

为了检测冷冻压力下海藻糖积累的作用，我们构建了海藻糖酶基因ATH1、NTH1和NTH2的各种单基因突变株和双基因突变株，并对突变株的海藻糖积累情况和耐冷冻能力进行了检测。

By contrast, in liquid transients, pressures and flow pattern undergo smooth transitions and transient effects are small.

与气量突变相比，液量突变引起的压力和流型变化较平缓，瞬态效应小。

Stock supply will slightly reduce the pressure, first in the slowdown in the pace of IPO; Second, the size of non-market conditions as a result of the mutation may temporarily slow down the reduction of the original plan, but the long term, to limit the sale of shares of further standardize and improve the stock supply is still bound by the pressure of the most important impact on the market is still very critical; Third, some state-owned listed companies to buy back shares to reduce the absolute number of shares.

股票供应量将略有减少压力，在首次公开招股的速度下滑影响，第一，第二，大小非作为市场条件突变的结果可能会暂时放慢了原计划减少，但是从长远来看，限制了进一步规范和改善供应出售股份的股票仍是由市场上最重要的冲击压力的约束仍然是非常关键的；第三，一些国有控股上市公司回购股票减少股票的绝对数量。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
