Chapter 0218 Emergency Grant

Generally speaking, the difference between ammonite and nautilus shells is that the shell of ammonite is slightly thinner, the body tube is relatively simple, and the partition wall extends toward the shell opening.

In addition, the most important thing is that ammonite has complex sutures, while nautilus has no sutures. It is the line where the ammonite partition wall contacts the inner surface of the shell wall.

The sutures of other cephalopods are simple arcs or straight lines.

However, the sutures of ammonites are quite complex, so any description and classification of ammonites must be based on the discussion of sutures.

The part of the suture that bends toward the shell mouth becomes the saddle, and the part that bends in the opposite direction becomes the lobe.

Then they are named as abdominal saddle, ventral lobe, dorsal saddle and dorsal lobe according to their different positions in the shell circle. According to this, there are several types of sutures.

One, composed of some simple saddles and leaves, is called an ammonite suture, which is possessed by most Paleozoic ammonite animals.

Second, it consists of serrated or edging leaves and a round uninterrupted saddle, called an ammonite suture.

Odontozoites are classic examples of sutures with this type, and they were dominant in the Triassic of the Mesozoic Era.

Third, sutures consisting of leaves and saddles that are both edged and differentiated into many leaflets are called ammonite sutures, which mostly appeared in the Jurassic and Cretaceous.

There are several different schemes for the systematic classification of ammonites. The commonly used one is to divide the ammonite subclass into 9 orders:

It resembles an ammonoid order, with a posterior neck-type body tube ventrally and complete lateral lobes or the lateral lobes moved laterally during ontogeny to form more umbilical lobes, Devonian.

It is further divided into 4 suborders.

Baculolith suborder, the shell is straight or arcuate, spherical carcass, with ventral leaves, sometimes with full lateral leaves.

A suborder of ammonoids without edges, annular shell or convoluted shell, early umbilicus, full lateral leaves, Early-Middle Devonian.

Similar to the ancient ammonoid suborder, the umbilical lobe remained at the umbilical line or was displaced laterally during ontogeny, late Early Devonian to Late Devonian.

In the suborder Ammonoides, during the ontogeny process, the lateral and ventral lobes split to produce a series of costal lobes and occasional lobes, early in the Late Devonian.

Prismoidales, ventral quadrilateral tubes, ovoid carcass. During the ontogeny process, one to several lateral lobes in the suture were formed by the lateral saddle-sellar fissures, Middle Devonian-Permian.

It is further divided into 2 suborders.

The universal law of energy transformation and conservation is the concrete manifestation of all macroscopic processes involving thermal phenomena.

It is one of the basic laws of thermodynamics.

The first law of thermodynamics is a statement of the law of conservation and conversion of energy.

"But the fastest one is now ready to open the missile silo and will be launched in 1 minute! The missile is expected to intercept three unknown objects in the stratosphere!"

"Stratosphere? Can it really be intercepted?"

Hearing this, Zhou Wenwen couldn't help but frowned, retrieved the information, and thought about it carefully.

The stratosphere refers to the troposphere upward to around 55 kilometers above sea level.

This layer is the place where ozone is concentrated in the earth's atmosphere, especially in its lower part, that is, the ozone concentration is maximum at an altitude of 15 to 25 kilometers, so this layer is also called the ozone layer.

Since the ozone layer can absorb a large amount of solar radiation heat and greatly increase the air temperature, the biggest feature of this layer is that the temperature increases with height, and the temperature increases to a maximum value at the top.

Although there is very little water vapor in the stratosphere and weather phenomena are relatively rare, with the launch of weather rockets and satellites, it has been discovered that changes in airflow in this layer are closely related to weather changes in the troposphere and influence each other.

Zhou Wenwen was most concerned about Tony now, he asked.

"Does Tony already know? How is his current situation?"

Hearing this, the hunter quickly called up the satellite, tracked Tony's signal, and followed the data.

"Jarvis connected to the military networks of various countries. After discovering it for the first time, he notified Tony. Now the satellite has detected that he is flying to the Johnson Space Center in Houston."

"Johnson Space Center? Where is this?"

Hearing the unfamiliar geographical terms, Zhou Wenwen couldn't help but show a stunned expression. The hunter had no choice but to call up the data and replied.

"The Johnson Space Center is also the Lyndon B. Johnson Space Center, Lyndon B. Johnson Space Center, JSC. It is located on the west bank of Clear Lake in Texas, about 40 kilometers away from downtown Houston, covering an area of ​​4.38x107 square meters."

"There are more than 140 buildings of various sizes in the center, which house various equipment and facilities for aerospace activities and applied research."

"An agency under the Aeronautics and Space Administration at Johnson Space Center. It has been responsible for coordinating and managing manned space missions since 1961. Its mission control headquarters is located at Johnson Space Center."

(But all NASA manned missions since Gemini 1965 in 4 have not been directed from here. Previous Mercury missions were directed from Langley Research Center in Virginia.)

Hunter: "Currently Johnson Space Center is responsible for controlling space shuttle flights and the status of the International Space Station."

"In addition, the Johnson Space Center also has an astronaut training center. The entire facility covers an area of ​​655 hectares and has more than 1.4 employees."

"The center leads various research projects related to human exploration and development of space civilian programs, and its main service targets are the Aeronautics and Space Administration and some commercial organizations..."

"...Master, it's too long. Don't read it. Please help me get Tony on the phone."

Seeing that the hunter wanted to continue talking, Zhou Wenwen quickly interrupted the hunter and issued a new order, and the hunter naturally accepted the new order.

"Yes, master, the satellite line is being connected. The connection is completed."

As soon as Hunter connected the satellite line, Zhou Wenwen asked impatiently, but it took a while before Tony replied, and the noise was loud.

"Tony, where are you?"

Tony replied: "I'm on vacation....//--/-- Johnsonxdryfrxrf Center, where are you?"

"I am now in the sky above Qatar, preparing to use laser weapons (space-based weapons) to intercept. What about you, what are you going to do?"

Because space-based weapons require concealment, Zhou Wenwen did not mention space-based weapons directly in his words, but used laser weapons instead. Tony, who would understand that it was the space center that had interfered with the call, did not hesitate to launch the Mark 2 armored flight. Once in the air, I decided to continue the call.

"If you want to use a laser weapon, I'm afraid it won't be enough to fight three at once. And is your weapon powerful enough?"

The smart Tony heard the concealment in Zhou Wenwen's words, and directly asked the key to the matter. After hearing Tony's words, Zhou Wenwen, who lacked knowledge in this area, couldn't help being stuck for a while, and quickly changed the topic and said: " What are you doing in Hughes?"

"My Armor Mark 2 may not be able to fly up to the troposphere or even break through the tropopause. I learned this from Jarvis..."
