致密

The origin of tight sandstone reservoir is due to the cementation of quartz and crystallization of clay minerals from the pore water.

2砂岩储层致密的原因是石英的胶结作用和粘土矿物的沉淀。

Jadeite Jade, as a kind of Jade with high quality, has many excellent gemological characteristic, such as gorgeous and changefully color, the tightness and the hardness of its texture, beautiful luster and transparence, and good toughness. Those characteristics attribute to its petrological and mineralogical characteristics.

翡翠作为一种优质的玉石，具有很多优良的宝石学特征，如颜色的艳丽和丰富变化，质地坚硬致密，漂亮的光泽和透明度，良好的韧性等，这些特性都归因于其岩石、矿物学特征。

According to the geology and well test data of Neopaleozoic tight reservoir in Tabamiao region, we begin with the conventional log response characteristic analysis and extract the classification ratio parameters to visual identify and evaluate reservoir characteristic. That is the lithologic, electric and physical ratio parameters and gas synthetical characteristic exponent.

依据塔巴庙区块上古生界致密储层各种地质、试井成果等的资料，从常规测井响应特征分析入手，提取建立了一套直观识别评价储层特征的分类比值参数，即"四性"测井特征参数：岩性比值参数、电性比值参数、物性比值参数和含气综合特征指数。

The animal (whose name literally means "little Chincha") is named after the Chincha people of the Andes, who wore its soft and dense fur.

这种动物名称的字面意是"小chincha"是命名后， chincha人民的安第斯山脉，他们的毛皮致密且柔软。

Results indicated that the variation was significant from treatment to treatment. S-deficiency caused bulging chloroplasts, loosening and dishevelled grana lamella, reducing organelle, and damaged chondriosome in mesophyll cells of the leaves, and empty cells of the roots, while S-excess, however, led to densification, condensation and randomization of grana lamella of the chloroplasts of the leaves, and separation of cytoplasms from walls of the cells of the roots.

结果表明，受S素营养胁迫的水稻，其根系及叶片的超微结构均发生了显著的变化：低S胁迫会造成水稻叶片叶肉细胞内的叶绿体结构肿胀，基粒片层松驰、散乱，细胞器减少，线粒体结构被破坏，根系细胞内几乎没有内含物；S浓度高则会使叶片叶绿体基粒片层致密、浓缩，无规则化，根系细胞发生质壁分离。

This shift shall greatly benefit earth and mankind alike as many of such entities sit in a density of the old consensus thought-form, which is black, brown, gray, mucous yellow and green in color if viewed clairvoyantly.

这个变化会大大有助于地球和人类，因为很多这样的存有们坐落在旧一致实相致密的思想形态中，如果透视他们的话，是黑色、褐色、灰色、粘黄和粘绿的色彩。

"The pump casing shall be constructed of close-grained cast iron, aSTM a48, Class 30, and shall be of sufficient thickness to withstand all operating pressures and mechanical stresses."

泵壳结构应该采用符合美国材料试验协会aSTM a48级别30致密铸铁制造，应该具备足够的厚度，能够承受所有运行压力和机械应力。

Mixing, pouring and compacting of the green concrete so that the raw materials are distributed evenly throughout the mixture and do not bleed, and a close-grained texture for the concrete is achieved

环保混凝土的混合，浇筑压实，可以促使原材料均匀分布，不至于渗漏，使混凝土获得致密的晶体结构。–混凝土固化，使得靠近表层的部分达到特性。

Chromatin hetropycnote partly in spermatogonium, then become highly coacervate to form chromosome at the stage of spermatid and at last decondense at the stage of spermatozoon.

染色质在精原细胞中为部分异固缩，在精母细胞中高度凝聚为染色体，在精细胞及精子中为均匀非致密态。

It can also spare the building of cofferdam to drain off water in the cons- truction of wharves.

本文叙述在坡度呈35～40°的致密角砾凝灰岩海岸上，建造一座岸壁码头的实例。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
