难以说明的

Based on＂The Data Bank System of the Standard Phonetic Features of Different Level in PSC＂, the thesis analyzes the variants of affricative versus fricative in syllables: z, c ,s - zh, ch, sh - j, q, x which are obscure in physiology; analyzes timbre phonetic variants aroused from the different match of seven main simple vowels and initials as well as the tonal patterns with the help of drawing the synthetic spectrograph and pitch spectrograph. So that the data can be offered to describe phonemes in 396 syllables in common use according to the acoustic analysis.

本文在"普通话水平测试各等级标准语言特征数据库系统"的支持下，通过制作396个常用音节语音样本的音高图和综合语图，考察在普通话教学和测试中从生理角度难以准确把握的一组仅有细微差异的塞擦音和擦音声母z、c、s-zh、ch、sh-j、q、x在音节拼合中的变体；考察7个主要单元音在与不同声母拼合构成的音节中音质上的变化模式；考察四个声调的变化形式，力图从语音声学物理特征角度的分析中为普通话常用音节音位语音规范度的描写提供客观的数据说明。

Because of the effect of catabolite repression and synergistic mechanism between pructs, the degradation of succinonitrile is promoted while the degradation of alkanes is inhibited in the mixed system of culture medium.

废水中烷烃质量浓度低，烷烃降解菌不能发挥其高效的降解作用，丁二腈质量浓度较大，降解效果明显，9h降解率可达到100%；腈纶废水经混合菌9h处理后，田氏去除率仅为29%，说明实际废水是个很复杂的体系，仅依靠个别高效菌株难以达到理想的整体处理效果，必须构建更多种类的具有协同作用的高效菌群，才能在实际应用中取得满意的结果。

It's true, as was just mentioned, that Davidson doesn't purport to offer a complete account of what determines the object of given responses. But we may well worry that the shared-cause requirement is so undiscriminating that it can seem motivated only if we elide, as Davidson sometimes seems to do, the difference between it and the requirement stated in terms of judgment.

如刚才提到的，Davidson并不试图提供一个对'什么规定了给出回应的对象'以完全说明，而我们可以恰当担心"对'被分享的原因'的必须"是如此难以识别出，以致仅当我们取消在它和根据判断所陈述的必须之间的区别时它才似乎是能被激发的，如Davidson有时似乎做的那样。

Explanation: Awkward and angular looking, Apollo 17's lunar module Challenger was designed for flight in the vacuum of space.

说明：难以操纵而且外表生硬，阿波罗17号的挑战者登月舱，是被设计来用于在真空空间飞行的。

Currently, the high occurrence of malversation among Chinese administrative staff is impossible to be prohibited due to the present deficient system structure and system arrangement, which allures the staff into corruption actions and meanwhile provides them with chances, with little probability of being discovered and punished.

当前中国的行政人员腐败现象之所以层出不穷、居高不下并难以禁绝，说明现行的制度结构和制度安排存在着重大缺陷，它诱使一些行政人员从事腐败活动并提供了相应的机会，而从事腐败活动被发现和受到制裁的机会很小。

For the ternary system results were in qualitative agreement with experimental values.

这说明使用简单的势能模型，难以准确计算这些物系的相行为。

Several studies indicate a worse outcome in patients who received fasciotomy compared with those who did not.7, 11 It is felt to be indicated only in a potentially viable extremity that is pulseless due to elevated intracompartmental pressure.18 Fasciotomy was felt to be useful in preventing cases of Volkman's ischemic contracture after the Tangshan earthquake.3 In Israel, fasciotomy was reserved as a treatment of last resort in cases refractory to the use of intravenous mannitol.7

几项研究表明，采用筋膜切开术的患者后果比未手术者更严重。这说明仅在可能的极端情况下筋膜间区压力升高才会导致无脉动现象。在唐山地震后，筋膜切开术对预防前臂缺血性肌挛缩有效。在以色列，筋膜切开术被做为难以采用静脉输注甘露醇病人最后的治疗方法。

Correlation analyses on the contents and ratios of endogenous hormones with selfing fertilities showed that selfing fertility was not determined only by one single hormone level, but partially affected by the joint action or balance of several hormones in Nongken58S original and untransformed regenerant controls under long-day. Our results did not support different already proposed hypotheses on one single hormone action in fertility expression of PSGMS rice.

1通过对因受环境低温影响而在长日条件下不育性部分逆转的原始材料和组培再生后代材料的自交结实率与内源激素水平及比值相关性分析表明，农垦58S育性转换并非取决于某种单一激素水平的改变，而可能与多种激素的共同作用和平衡关系有关，从而说明&众说纷纭&的单一激素作用的假说难以成立。

This opinion oppugns the basic jumping-off point of many technological innovative studies in China presently.

主要包括：1、论文指出，现阶段我国工业技术创新难以有大的进展或进步并不能说明中国工业企业不理性，而是刚好相反，这是企业理性的行为。

These results suggest that RBE3 is bound to starch granule due to its high affinity to starch in rice endosperms.

综合以上研究结果说明RBE3存在于水稻胚乳的淀粉之中是由于RBE3与淀粉葡聚糖链具有较高亲和性而难以和葡聚糖链解离，进而随着淀粉粒的增长而被其包裹。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
