The findings indicate that there are many micro-crannies developed in marlite, which can be seen under the Scanning Electron Microscope. The micro-crannies are the precondition of karstification process. Also, the calcium carbonate is dissolved through some chemical processes, and lots of mineral mud are carried away by mechanic erosion. The karstification process results in not only mineral component transformation, but also the rock mass structure alterations.

结果表明：微观下泥灰岩岩石中发育许多微小的裂隙，为溶蚀作用的进行提供了前提条件，另外泥灰岩中大量的泥质物随可溶岩的化学溶蚀过程发生了机械侵蚀作用：泥灰岩的溶蚀作用一方面引起矿物成分发生改变，另一方面导致岩石结构的变化。

The value changes for your program only, not for GDB itself. value may be any string; the values of environment variables are just strings, and any interpretation is supplied by your program itself. The value parameter is optional; if it is eliminated, the variable is set to a null value.

这个改变只针对你的程序，不影响 GDB 本身。value 可以是任何字符串，环境变量的值仅仅是字符串，任何解释都是你的程序自己的。value 参数是可选的，如果没有，变量会设为空值。

In experiments ,an injection of cytoplasm from dextral eggs changes the attern of sinistral eggs ,but an injection from sinistral eggs does not infl uence dextral eggs .

在实验中，用取自右旋卵子的细胞质进行的注射，可改变左旋卵子的模式；用取自左旋卵子的细胞质进行的注射却不能影响到右旋卵子。

Thirdly, the precipitation phenomena and pH-curves of the compressed COi-ethanol-water system with BSA or lysozyme were studied, and it was found that: BSA would precipitate when pH of solution decreased close to isoelectric point, and the precipitate would redissolve when pH decreased further.

蛋白质分子结构数据表明，乙醇还在一定程度上改变了蛋白质分子的表面结构，这影响到了蛋白质的缓冲能力等特性，从而乙醇对加压CO_2-乙醇-水-蛋白质多元体系的pH变化有降低的作用，这使体系可处理的蛋白质浓度较加压CO_2-水-蛋白质体系大幅度提高。

The FDA requires a full evaluation of a genetically engineered food crop when uncharacterized DNA sequences are used, or when food products may contain significantly altered nutrient levels, different compositions from substances currently found in foods, allergenic proteins, new antibiotic resistance markers, or levels of toxins significantly above those found naturally in edible varieties of the same species.

当使用不明特征DNA时或者当食物产品营养水平可能显著改变的、有不同于目前食品中组成成分的、有过敏原蛋白的、有新抗菌素抗体标记的或者毒素水平显著超出同物种可食用各品种中天然存在的这些情况出现时，食品药物管理局将要求完整评估一种基因工程处理过的粮食作物。

At first "the pensioners' line" was less productive. But the firm brought it up to the level of the rest of the factory by introducing 70 relatively small changes, such as new chairs, comfier shoes, magnifying lenses and adjustable tables.

首先，&领养老金生产线&的生产能力较低，，但是公司通过更换新椅子，更舒服的鞋子，放大镜和可调整的桌子等70个比较小的改变后，&领养老金生产线&的生产水平达到了其它生产线的水平。

As our inventions shift from the linear, predictable, causal attributes of the mechanical motor, to the crisscrossing, unpredictable, and fuzzy attributes of living systems, we need to shift our sense of what we expect from our machines.

由于我们的发明从机械动力线性的、可预见的、具有因果关系的属性，转向生命系统的纵横交错、不可预测、模糊不清的属性，我们也需要改变自己对机器的期望。

There are as many as 50 body parts, from your skin to your corneas, that can save or transform the life of a potential recipient, but for many families lost in grief, the idea of dismembering a loved one is more than they can bear.

结构分析：这句是由but 做连接词的两个分句。第一个分句中包含一个由 that 引导的定语从句修饰body parts；第二个分句的主语是the idea。句子译文：人身上有50中可捐献的器官，皮肤和角膜都包括在内。每种都可能救活一个人或改变他们的命运。

Through the topographical survey, literature research and analysis of the remote sensing images, we shall emphasize on the five factors of water conservancy, water flow, streams, water retaining and water utilization in the upper reaches of the river, which are interacted and interplayed.

研究结果表明，漓江为雨源性河流，降雨时空分配极不均匀，70%的降雨量集中在漓江上游区域，全年62.7%降雨量和降雨时间集中在四个月内(即4～7月)，最大的日降雨量可达415.8mm；降雨量最小的月份出现在12月至翌年1月，仅100～110mm，占全年降雨量的6%左右，由此直接影响流域河川径流季节性的变化，造成洪水期和枯水期现象，周期性水量的变化是不为人们意志改变的一种自然规律。

Through scheduling process analysis of periodic task, the waiting limit formula of each task in ready queue was obtained while guarantees its deadline. In addition, some properties, such as final preempting time was deduced and the necessary condition of periodic tasks preempting behavior was described quantitatively. Based on them, a micro scheduling preemption model for periodic tasks in ready queue was put forward, which decreased the number of preemptions and optimized system performance through changing the preempting sequences.

通过分析周期性任务的调度过程，得出在确保任务不错过截止期条件下，各个任务在就绪队列中可等待的最长期限计算公式，并根据公式推导出任务满足截止期的最后抢占时刻等属性，从而定量地刻画了周期性任务抢占行为发生的必要条件，提出了一套对周期性任务的就绪队列进行微调度的抢占模型，通过改变抢占关系来减少抢占次数、优化实时系统性能。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
